QDeo-roof fan smoke

Do - smoke derivation

PVC - Petrovkomplekt.

When the fire occurs and the fire begins, for people who are indoors are dangerous not only the fire itself, but also combustion products that are able to lead to complete disorientation and loss of consciousness. For this reason, it is important from the very first seconds to ensure the removal of smoke with the help of a special ventilation structure.

The fire occurs due to the careless handling of fire. The focus of fire can be in difficult places, so arriving firefighters can not immediately neutralize it. The main danger to the life of people represent combustion products and an increase in temperature. In order to protect the evacuation by fire system specialists, smoking roof fans were developed.

Types and characteristics

The root fan is one of the aggregates of the smoke removal system, which is designed to remove the hot gas mixture from the building. It is he who takes on the main heat blow and, thanks to his design, continues to work until the full elimination of fire. The temperature of the removed gas mixture can reach +900 ° C.

The root fans of smoke removal are three species, depending on the method of removing the gas mixture, the axial, diagonal and radial.

- One of the simplest in its design. It is a cylinder with blades in a protective casing. Rotating, the screw blades artificially reduce the pressure and thereby pull out gas mix. Appearance resembles a simple home fan.

The diagonal fan is an elongated drum, inside which one or more impellers are placed. The blades are sucking the hot air in the direction of the axis, and throw it out into the diagonal, hence the name. A plus of such an aggregate is its high performance and low noise.

The centrifugal or radial fan displays smoke from the room due to the special design of the blades. When working, such a fan misses the products of burning to the street due to centrifugal force created by curved blades. With a high air exchange, such a fan is sufficient, therefore it is established, as a rule, in industrial buildings.

Smoke dealers' roof fans are automatic and manual. Automatic devices Equipped with special sensors. They are triggered by increasing the temperature. Manual models Equipped with a special button for switching on.

Criterias of choice

Before choosing a roof fan, you must consider a number of criteria:

Build the design of the roof fan are produced in the factory. It helps to avoid the inaccuracies of the design that reduce aerodynamic characteristics. As a rule, the smoke removal fan model is chosen at the design stage. But if the fan has become unusable during operation, then it can be selected independently, according to the existing nomenclature.

In the designation of the fan BP-10-Du-2h / 600 (400) ° C-5.5 / 710, the letters indicate its appearance ("BP" - radial, "Du" - smoke removal). Cultural values \u200b\u200bin order determine its main parameters:

• "10" - wheel sizer;
• "2h" - the limit of fire resistance;
• "600 (400) ° C" - the temperature of the transferred gas mixture;
• "5.5 / 710" - engine characteristics Power and turnover.

Some manufacturers are added to the standard nomenclature direction of rotation of the wheel and the position of the housing in degrees.

Installation of devices

Installation of the fan is envy on the type and angle of inclination of the roof. To begin with, the hole is done and installed in it check valveIf necessary, the vibrating absorbing structure is mounted.

Then the pallet is fixed, and on top of the fan design itself. It is important to prevent skew when installed, since in such positions the fan will not work. After fixing, it is necessary to treat all the compounds with a special refractory sealant.

When choosing a roof fan of smoke removal, it is necessary to remember that it helps people will not poison and do not burn combustion products during a fire, so its choice must be thought out thoroughly. It should be powerful, compact, low noise. The design should be light and fire-resistant.

Recently on russian market Ventilation equipment There is a sharp increase in interest in air ventilation systems and to the main components of these systems - smoke fans. This is largely caused by the statement from May 1, 2009 new " Technical Regulations On the requirements of fire safety, "one of the arrangements of the rules of which is entirely devoted to fireproof requirements for heating, ventilation and air conditioning systems:" Rules of Rules 7.13130.2009 Heating, ventilation and air conditioning. Fire Requirements "

The production of fans of smoke removal is one of the main activities of the company internal technology. This article discusses the following issues:

Types of smoke farming fans

The main differences in smoke fans are the design of the housing and the type of impeller. The most common and sought-after fans in the Russian market are Roof radial fans and Radial fans with a spiral case .

Roof radial fans

Roof radial fans have a number of advantages over the rest.

Firstly , Fans are placed on the roof, the area of \u200b\u200bwhich is usually not used. This allows you to abandon the equipment of special premises to accommodate smoke fans, and, as a result, enlarge useful Square premises.

Secondly , Fans are placed on a mine from construction execution, which in many cases allows you to abandon the laying of the vertical duct. Also, an explicit advantage is that air emissions are made directly from the fan into the environment, and there is no need to use the air duct to remove the combustion products from the fan.

The design of the roofing fans of smoke removal is used in two types: fans with emissions to the side and emissions up. When choosing a fan body design, you must consider one of the requirements regulatory documentation: Emission to the atmosphere should be provided at a height of at least 2 m from the roof of combustible materials; The emission of combustion products is allowed at a smaller height when protecting the roof of non-combustible materials at a distance of at least 2 m from the edge of the outlet hole. The advantage of the fan with a release on the parties is its relatively low cost.

The advantage of the fan with emission up is a higher location of the burning product emission relative to the level of the roof. A mounting glass is used for mounting the roof fan of smoke removal. The top flange of the mounting glass is connected to the outer flange of the fan. The bottom of the mounting glass has various connecting dimensions depending on the design of the mine. Anyway, the lower part of the glass relies on the mine. The weight of the fan is transmitted through the mounting glass at the mine. There is standard the lineup Installation glasses, which is presented in the VKT product catalog. Also, depending on the design of the mines, our designers pick up glasses with individual connecting dimensions. In certain cases, the use of a warmed mounting glass is required. In this case, the glass body is covered with thermal insulation, and insulated air damper is placed inside the glass.

Radial fans with a spiral case

Sometimes the use of roof fans of smoke removal is not possible. In these cases applies Radial fan with spiral housing . The advantage of this fan is that it is possible to post it almost anywhere in the building or near the building, given the equipment placement standards. In addition, the air duct can be connected to this fan both at the inlet and the output. Given the fact that the fan is able to develop pressure up to 2000 Pa, the burning of combustion products from the fan is possible to produce quite long distances. Air ducts both on the suction side and on the discharge side should have a certain fire resistance. As a rule, the required fire resistance is achieved by coating the air ducts with flame retardant.

Calculation and selection of smoke fan

When calculating and selection of smoke removal fans, it should be considered that all the characteristics presented in the catalog correspond to the normal atmospheric pressure and air temperature of 20 o C. To recalculate the fan characteristics to the temperature of the removed smoke, the pressure is necessary to multiply to the coefficient 293 / (273 + T) where T is the temperature of the removed smoke in O C.

The company McTechnology produces fans from back curved blades. When selecting a fan for one working point, several fans are suitable for one operating point. As one of the options, select the fan that has less rated engine power, if this characteristic is relevant. IN otherwise It is recommended to take that fan, the size of which is less - in order to reduce its cost.

It is also necessary to remember that at different points of the working curve, the fan consumes different power, that is, the rated power of the engine depends on the characteristics of the network.

Principle of operation and control of the smoke fan

The principle of operation and control fan of smoke removal is quite simple. A control shield is used for the fan. The signal to turn on the fan comes to the control shield from the fire automation shield.

As a rule, the smoke removal fan is used only in the air ventilation, but can sometimes be used in systems of sociable ventilation. In this case, the frequency converter is used, which, when receiving a signal from the fire automation shield, increases the speed of rotation of the fan. This scheme is sufficiently beneficial because it allows you to abandon the additional system of sociable ventilation, using only smoke removal system.

The axial fan is usually located in the cylindrical body of the impeller (K), fixed on the motor shaft. Additionally, the input guide apparatus (VNA) and the hiding apparatus of the Ca can be used.

In our company, axial industrial fans are manufactured according to schemes to and k + sa.

In the axial fan, the movable medium passes along the axis of rotation of the impeller.

The main part axial fan It is an impeller, due to the rotation of which part of the drive energy is transmitted to the creation of a certain pressure and the speed of movement of the moving medium.

The impeller consists of a sleeve and blades placed evenly around the circumference in a certain way. The blades are performed by bulk or sheet and can be swivel or fixed.

The hiding apparatus (CA) is used to convert dynamic pressure associated with the flux twisting speed behind the impeller, in static. At the same time, static pressure and static efficiency increase without increasing power consumption. In some designs, the Ca performs additionally and the functions of the power node, where the motor or bearing unit can be placed.

Fans Roof axial Supply Types of CKOP and VKP-K
The roofing fans are used in the system of air ventilation ventilation (PD) and installed on roofing buildings and structures.
Fans supply outdoor air in the premises provided by P.P. 7.14 CP Rules 7.13.130 "Heating, ventilation and air conditioning. Fire safety requirements, "ensuring the disadvantage of ways to evacuate people in case of fire.
The use of fans simplifies ventilation system, saves space technical premises and regulates P.P. 7.17 SP 7.13.130.

VKOP
CKOP type fans - simple and economical option roofing installation Supply ventilation.
The CPOP can be installed on the air duct or prepared root base. In the absence of a prepared foundation, the CCOP is recommended to be installed on the roof on a glass of a mounting type of a QMS or SMET using an adapter type in a SMC.

The VKP-K fan is a complete installation of the airfield with the execution options for any project requirements.

Installations such as an efforts are used in aircraft ventilation systems (PD) and installed on roofing buildings and structures.
When installing installation without air ducts on the suction side, an input confusion type of the KS-W-in with a protective grid is used.
To reduce dynamic pressure at the output from the installation, it is recommended to use the output diffuser of the DV-C. type.

Vof-D.
A fan axial torch for smoke pulp systems in a fire is made based on a standard axial fan for smoke removal systems during a fire of type of type 13-284.
The fan is installed vertically on a special adapter for a subsequent installation on a standard glass of the QMS or SMET type.
Around the fan is a casing in the form of an octahedron and truncated octal pyramids in the upper and lower parts of the housing.
The air outlet from the fan is closed with a petal check valve that fully protects against atmospheric influences.
The use of such casing determines modern design The fan provides when working the ejector effect, which actually increases air performance.
Application In the design of the axial fan, its field of parameters complements the roof radial fans and provides ample opportunities for the selection of fans.

VKP-S.
The fan of the roof axial trimmed type PCP-C is primarily used in the systems of the supply of anti-ventilation (PD). The fan can be used both as a regular trimmed roof.
The fan consists of a typical axial fan different performancesinstalled on a special adapter for the subsequent installation on a standard glass of the type of SMP or SCM.
Around the fan is a casing in the form of an octahedron and truncated octal pyramids in the upper and lower parts of the housing. In the casing are located rectangular holes With protective nets for air intake.

The use of the VKP-C fan in a pair with a fan of the QPF creates on the roof of the building a harmonious pair of industrial installations created in one style and having a modern design.

IN TO
The roof axial fan is manufactured based on the standard axial fan in 13-284.
To improve operational characteristics, the fan is equipped with a confusion and diffuser. The fan is installed vertically and has an umbrella to protect against atmospheric precipitation. A small grid in the umbrella is guaranteed to protect the air channel from foreign objects. To install the fan on the roof, it is convenient to use a standard glass of the type of a QMS or a SMC with the corresponding adapter in a QMS.

EKO-K.
Fan roof axial with valve (based on in-13-284).
The fan has a built-in check valve that prevents the penetration of atmospheric air and precipitation to the serviced ventilation channel When the fan is turned off.

ECFo is made in various versions:
01 - with outer casing, providing additional protection of the fan body and valve, as well as improving performance features due to the ejection effect;
02 - a simplified version, applied during installation in cramped conditions;
03 - Completed with an umbrella for additional protection against atmospheric precipitation.

The Fans of the EAS and ECFO-K, thanks to another field of parameters, complement the range of radial-type roof fans.

To reduce the levels of vibration transmitted from fans to base and attached air ducts, use of different types Vibration insulators and flexible inserts.
