Is there a relationship between the wind speed of the air shower and the dust removal effect of the air shower?
Is the wind speed of the air shower related to the dust removal effect of the air shower? The wind speed of the air shower is slightly different from the dust removal effect of the air shower, but there are many reasons for the dust removal effect of the air shower, such as the use of the site. According to the research results of the air shower room, when the wind speed of the air shower room can only be above 20m/s, the air shower dust removal efficiency can almost reach a larger value. The wind speed of the air shower can be adjusted to ≥22~25m/s. For dust of different particle sizes, under the same wind speed, the larger the particle size, the better the dust removal effect.
In practice, because the air shower is located between the clean area and the non-clean area, and it is used frequently, the resistance of the two-stage filter rises rapidly, so although the initial wind speed of most air showers exceeds 20m/ s, but after a period of use, the wind speed will decrease, and the dust removal efficiency will drop rapidly.
In addition, the wind speed mentioned by the air shower manufacturer usually refers to the wind speed at the outlet of the nozzle, and the wind speed on the surface of the human body or the goods is much lower.
Therefore, we suggest from a technical point of view: for the new air shower, the initial wind speed should not be lower than 25m/s, and better to exceed 28m/s in order to achieve the desired air shower effect.
