How to make a simple furniture spray booth

The feed wind speed is greater than 0.3m/s, but not greater than 06m/s; the noise is not greater than 75dB; the illumination in the workroom is not less than 500lu; the filtering and dust removal effect reaches above 98.

1. Determine the reasonable configuration form.

2. Determine a reasonable average air flow rate on the horizontal plane of the spray booth.

3. The air supply and exhaust systems should be properly matched to ensure a slight positive pressure in the spray painting room.

4. The lighting layout is reasonable.

5. The paint mist purification method is reasonable and cannot discharge seriously polluting gases into the atmosphere.

In addition, the elimination of static electricity must be considered during design; the lamps and switches selected must be explosion-proof to avoid danger when turned on. It must also comply with the relevant laws and regulations of our country. Such as GB3096 urban area environmental noise standards, GB7691 painting operation safety regulations, GBJ4 industrial enterprise three waste emission trial standards, GB14444-93 spray booth safety technical regulations, etc. Extended information

There is usually a pressure difference gauge installed before and after the filter. When the pressure difference reaches a certain value, the filter element should be replaced. The filter element is made of non-woven filter material.

Generally, the air is sucked from outside the factory building. The air suction outlet should be located in a place with less sand and dust when strong winds occur. It should be far away from the exhaust outlet of the spray painting room or on the upper side of the wind direction. The air suction outlet should be installed with a metal mesh or Fence to prevent inhaled birds.

In order to prevent the noise from the fan from being transmitted into the spray booth, a muffler should be installed in the air duct behind the fan. The size of the fan is determined based on the size of the spray paint room and the number of air changes. The air supply volume per unit hour is the product of the number of air changes per unit hour of the paint spray room and the indoor volume. Temperature, humidity and dust removal degree depend on the type of coating being sprayed, coating appearance quality requirements and the operator's working environment.
