Embodiment 1

[0013] An air dust removal system for a paint spray booth, comprising an exhaust fan 2, a moisture filter device 3, and a bag filter 1, the exhaust fan 2 is connected to the air inlet of the moisture filter device 3, and the bag filter 1 is connected to the moisture filter device 3 air outlets.

[0014] The exhaust fan 2 draws the air in the spray booth into the moisture filter device 3, and after dehumidification, it passes through the bag filter 1 for dust removal.

[0015] In the present invention, the moisture filtering device 3 is composed of a ceramic tube, a sponge filler arranged in the ceramic tube, and an electric heating wire wound outside the ceramic tube, and a dehumidification valve 4 is opened on the top of the ceramic tube. An air inlet valve 5 and an air outlet valve 6 are respectively arranged on the air inlet and the air outlet of the moisture filtering device 3 .

[0016] After running for a period of time, when the sea surface filling is saturated with mo...

Abstract

The invention discloses an air cleaning system for a painting room. The air cleaning system comprises an exhaust fan, a water filtering device and a bag-type dust filter, wherein the exhaust fan is connected to an air inlet of the water filtering device; the bag-type dust filter is connected to an air outlet of the water filtering device. According to the air cleaning system, the water filtering device is arranged at the front end of the bag-type dust filter, and dust is filtered through the bag-type dust filter after water in air is absorbed, so that the air cleaning system has the advantages of high treatment capacity and low treatment cost.

Description

technical field [0001] The invention belongs to the field of environmental protection equipment, and in particular relates to an air dust removal system for a spray booth. Background technique [0002] When painting, the air in the spray booth contains a large amount of dust, which is very harmful to the human body. It is necessary to ventilate through the exhaust pipe to purify the air in the spray booth. Existing ventilation equipment generally directly adopts the exhaust fan to carry out forced convection of the air, which leads to the direct discharge of harmful dust into the atmosphere and causes environmental pollution. [0003] The bag filter has a large processing capacity and is widely used in industry as a dust removal device. However, the bag filter can only be used to deal with dry air. If there is heavy moisture in the air, the dust will adhere to the bag and the dust removal effect will be seriously reduced. . Contents of the invention [0004] The purpose ...
