Treatment equipment for coating waste gas

Abstract

The invention discloses treatment equipment for coating waste gas. The treatment equipment comprises an oxidizing chamber, and a first heat accumulation chamber, a second heat accumulation chamber and a third heat accumulation chamber which are communicated with the oxidizing chamber. The oxidizing chamber is provided with a heating device; each of the first heat accumulation chamber, the second heat accumulation chamber and the third heat accumulation chamber is provided with a gas inlet, a gas outlet and a hot gas inlet for suctioning hot gas; each of the first heat accumulation chamber, the second heat accumulation chamber and the third heat accumulation chamber is internally provided with a bottom heat accumulation layer, a middle heat accumulation layer and an upper heat accumulation layer; each gas outlet is connected with an air blower; the air blower is provided with an air outlet; and the air outlet is communicated with the hot air inlet through a pipeline. The treatment equipment for coating waste gas is simple in structure and low in maintenance cost; the heat accumulation chamber is reasonable in structure design and by the arrangement of multiple heat accumulation layers, heat is accumulated and stored stably and not liable to run away; and a filtering box is arranged in front of the heat accumulation chamber and use for filtering large-particle substances which can not be decomposed easily, piling and jamming of particle substances in the heat accumulation chamber are not liable to occur and then influences on the accumulation of heat are avoided.

Description

technical field [0001] The invention relates to a waste gas treatment device, in particular to a waste gas treatment device for treating the waste gas generated on spraying equipment. Background technique [0002] Air pollution sources are divided into industrial pollution sources, domestic pollution sources and traffic pollution sources. Industrial pollution sources involve a wide range of areas, and the composition of exhaust gas is complex. Especially in the painting industry, the exhaust gas from painting contains overspray paint mist, and the requirements for pretreatment of exhaust gas are very high in the process of treatment. [0003] At present, there are two types of treatment equipment for painting waste gas: dry type and wet type. The wet type treatment equipment currently mainly includes water curtains and absorption towers, etc., and waste liquid will be generated. Dry treatment equipment is currently mainly a filter composed of a single filter material. Becau...

AI Technical Summary

Problems solved by technology

Dry treatment equipment is currently mainly a filter composed of a single filter material. Because the organic waste gas generated by the spray booth in the painting industry contains oversprayed paint mist, the composition of the paint mist is complex, and the paint mist is easy to adhere to the filter material, resulting in Frequent replacement of filter materials and low removal efficiency of paint mist
