What standards are the performance of air shower nozzles based on?

 Air showers are indispensable purification equipment in industrial production. The clean air blown out by nozzles can remove dust, hair, dander, and other debris attached to the surfaces of people and objects entering the clean room, creating a clean production environment. Air shower nozzles are very important. Many users often make some mistakes when choosing. Today, Zhongjing Purification will introduce the design of air shower nozzles.

 The nozzle of the air shower is an accessory that most air shower users should pay attention to. The design of nozzles for supporting air showers in clean rooms (clean rooms and clean workshops) needs to consider the following elements:

1. Material

The nozzles of air showers are generally made of stainless steel and should comply with the regulations of GB11253. Its corrosion resistance is suitable for various cleaning agents and objects. The common nozzles on the market are stainless steel nozzles, followed by plastic nozzles. When using aluminum profiles, they must comply with the regulations of GB5237.

2. Shape

Nozzles typically come in flat and round openings. Flat openings can provide even airflow distribution, and circular openings can create a strong wind stimulation effect. Choose the appropriate nozzle shape according to different application requirements and object shapes. Generally speaking, spherical nozzles are often used.

3. Size and flow

The size and flow rate of the nozzle are determined based on the size of the air shower room, blowing requirements, and economy. Air shower nozzle outlet diameter: 30mm, wind speed ≥ 25m/s to ensure precise control of air volume in the air shower room. Larger nozzle size and flow can provide stronger wind power and blowing effect, but at the same time consume more energy.

4. Quantity and layout

Determine the appropriate sprinkler nozzles and layout according to the size and usage scenario of the air shower room. The number and arrangement of nozzles should be able to cover the surface of the object being sprayed. Technical parameters of air shower nozzles: single air shower: 12, double air shower: 24, multi-person air shower: 36, the height of the nozzle is 70-170cm, which is exactly the human body buttocks and above, this part is also dusty areas.

5. Position and angle

The position and angle of the nozzle have an important impact on the blowing effect. The nozzle should be positioned on the surface and at an appropriate angle to ensure that the airflow covers the entire surface and carries away dust or dirt. The nozzle is usually designed to rotate 360 ​​degrees to meet the blowing requirements of different scenarios. Although there are no nozzles at the bottom and higher parts, the nozzle angle can be adjusted so that no dead corners can be achieved.

 The above are the design specifications and requirements for air shower nozzles. An air shower made with good accessories is very important in our actual operation, otherwise, the air shower produced cannot truly achieve the purification effect. To maintain the hygiene and cleanliness of the air shower room, the nozzles also need to be regularly maintained and cleaned to prevent clogging and bacterial growth, and to ensure that people and objects entering the clean room can achieve the perfect effect of thorough dust removal.
