The external air hood of the dust removal equipment is introduced as follows:
The working principle of the external air hood is to use the suction effect of the hood to suck harmful substances into the hood at a certain distance from the suction port. The shape of the external air hood is basically similar to the shape of the umbrella hood. Therefore, it also Known as an umbrella cover, it is suitable for situations where the source of hazardous substances cannot be sealed or closed.
The invention has a simple structure and is convenient to manufacture. It can be divided into up-suction type, down-suction type, side-suction type, trough-side type, etc. (see Fig. 6). It is characterized by large exhaust volume, but is affected by the lateral airflow of the workshop Serious interference ...

What should you pay attention to when introducing the design of the external air hood of the dust removal equipment ?
When designing the outer gas collecting hood, factors such as the installation height of the process equipment and horizontal indoor airflow interference should be considered. If necessary, improvement measures such as enclosure, rotation, and lifting can be taken. The main issues that should be noted in the design are as follows.
Under the premise of not disturbing the operation of the process, the cover should be as close as possible to the source of pollution. This reduces interference with lateral airflow.
Add a flanged edge around the hood opening (to the vertical edge of the hood opening) to reduce exhaust volume.
The expansion angle of the hood (top cone angle of the umbrella hood) has a great influence on the speed distribution of the hood opening and the pressure loss in the hood. The design should be determined according to requirements.
When the size of the hood opening is too large to meet the above requirements, appropriate measures should be taken to ensure the air collection effect of the hood. The main measures include: ① Divide a large exhaust hood into several small exhaust hoods; (2) a baffle is installed in the hood; (3) a slit is set in the cover, and the wind speed of the slit is required to be above 10111/3, The wind speed in the static pressure box does not exceed 1/2 of the wind speed at the slit opening; (4) An air flow distribution plate is arranged at the cover opening.

In the production process of the factory, it is very important to handle the dust in the factory room. Vacuuming can effectively remove more smoke and dust pollution and speed up the production efficiency of the factory. Vacuuming can effectively ensure the neatness and sanitation of the factory processing, especially the dust removal equipment is very needed in the processing of food products. Only by properly using the dust collector equipment can the plant's production scale be increased. 为您提供更多的信息！ So at present, more and more enterprises choose industrial dust collector equipment.
