Special paint spray room cleaning device for effectively purifying and preventing clogging

Abstract

The invention relates to a special paint spray room cleaning device for effectively purifying and preventing clogging, and the special paint spray room cleaning device comprises a vertical purification tower. The vertical purification tower comprises a cone-shaped air inlet chamber, a purification chamber and an air outlet chamber from bottom to top in turn, the cone-shaped air inlet chamber is internally provided with a conical air diffusion plate, a cooling component, an air inlet pipe and a condensation discharge pipe. The purifying room is internally provided with an upper fixed plate, a lower fixed plate, an inner purifying layer and an outer purifying layer. One side of the air outlet chamber is connected with an air outlet pipe. The invention provides a special purifying device forpaint spraying room which can effectively purify and prevent blockage. The special paint spray room cleaning device is specially used for waste gas treatment in a paint spraying room after paint spraying treatment, can improve the effect of waste gas treatment and effectively purify organic solvents in waste gas. At the same time, the special paint spray room cleaning device can avoid blockage ofan adsorbent by the waste gas, has good adsorption and purification effect, fast speed, high adsorbent utilization rate, and large overall treatment capacity.

Description

technical field [0001] The invention relates to the field of waste gas purification and treatment devices after painting, in particular to a special purification device for a paint spray booth that can effectively purify and prevent clogging. Background technique [0002] For the organic waste gas generated during the painting process (mainly including organic solvents such as esters, alcohols, benzene, and ketones, and volatile organic compounds such as xylene, toluene, ethylbenzene, styrene, and formaldehyde), adsorption methods are usually used in the prior art And combustion method treatment, among which the adsorption method is mainly used in the purification treatment of organic waste gas or organic solvents discharged from chemical production such as paint, plastic, coating, rubber and so on. In the prior art, activated carbon is used for adsorption, but after the activated carbon has been adsorbed for a period of time, it needs to be regenerated, and the paint mist i...

AI Technical Summary

Problems solved by technology

The existing adsorption treatment device has the following problems when it is used as a purification spraying exhaust gas: 1. Since the exhaust gas in the spray painting room enters through an intake pipe, the distribution of the exhaust gas in the clean room is uneven, and the exhaust gas content in some parts is high , leading to the position with high waste gas content, the adsorption capacity of the adsorbent is large, the adsorbent is easy to lose the adsorption effect, the local position of waste gas content is low, resulting in unsaturated adsorption of the adsorbent, the processing capacity of the entire purification device is low, and the utilization rate of the adsorbent Low; contains a large amount of paint mist and organic solvents, the adsorbent is easy to block, and the service life of the exhaust gas treatment device is shortened; 2. It is difficult to effectively purify the organic matter in the exhaust gas in the spray booth, and the exhaust gas after treatment is difficult to meet the emission standards. 3 1. After the adsorbent has been used for a period of time, the adsorbent needs to be replaced regularly. The replacement of the adsorbent in the prior art is very cumbersome, and the replacement of the adsorbent is frequently changed, which is seriously time-consuming and laborious; the raw material cost of activated carbon is high, and the regeneration technology is not perfect. , the regeneration cost of activated carbon is high
