Ventilation and smoke exhaust of steel structure factory building

Steel structure factory buildings are generally naturally ventilated by roof fans and gas towers. The steel structure factory building does not have particularly high-power heating equipment, and the personnel are not very dense, and there is no peculiar smell or dust generation. The way of using roof fans and air towers is enough. But for some factories of hardware, casting and forging, clothing, plastics, electroplating, and electric welding, especially some factories that produce a lot of smoke and peculiar smell, natural ventilation can no longer discharge harmful gases. These gases accumulate in the mid-air of the factory building and form a smoke cloud, which will have a certain impact on the normal production of the factory building. The smog and high temperature weather will make employees feel very stuffy if there is no other ventilation equipment, which will affect production efficiency.

For a steel structure factory building with a large span, the best way to solve the ventilation and smoke exhaust problems is to install an exhaust fan with a large exhaust volume on the roof. Exhaust air to the outside constitutes indoor negative pressure and presses a large amount of fresh air into the workshop from the vicinity of the workshop to form air convection, so that the effect of ventilation and smoke exhaust is better.

Suggestions for ventilation and smoke exhaust in steel structure workshops are as follows:

1. Do not install wind balloons. A negative pressure fan with automatic exhaust is installed on the roof of the steel structure factory building, and a wind ball is installed, a part of the air will directly enter the steel structure factory building from the wind ball, and then be discharged by the negative pressure fan, which will form an air "short circuit" and cause Waste of resources.

2. If the workshop unit is to be designed in the steel structure factory building, it should be designed at both ends of the steel structure factory building, not on both sides. That is to say, the unit is best designed on the short side of the steel structure factory building. If it must be designed on the long side, the height of the workshop unit should not be too high to keep ventilation windows above the outer wall of the unit.

3. When planning automatic ventilation equipment, do not choose the traditional circular fan, but choose a square, large wind star negative pressure fan with rain-proof louvers. The square negative pressure fan is easy to install. The square, slightly lighter and thinner structure is very suitable for installation on the channel steel of the steel structure workshop.

4. It is necessary to reserve the hole for installing the fan. The weight of the fan is usually within 8kg, please consider the bearing problem. The general principle of the number of devices is: one fan is installed for every 100 square meters of factory buildings.

5. Choose a double herringbone air tower, which is easier to install and has a better ventilation and smoke exhaust effect. It is best to extend a part of the upper part of the air tower forward to keep out the rain.
