Description

Technical Field

[0001] The utility model belongs to the technical field of industrial waste gas treatment, and particularly relates to a DPA paint mist box-type filter box. Background Technique

[0002] As is well known, the spray painting industry is used in many commodities, such as: machinery, automobiles, furniture and other industries. No matter which industry or what kind of spray painting industry, the organic waste gas generated contains paint mist. During the spray painting process in industrial production, a part of the paint will form paint mist waste gas. The paint mist particles in the paint mist waste gas are tiny, have high viscosity, and are easy to adhere to the surface of objects. Moreover, the paint mist waste gas contains a large amount of toluene, which will produce a pungent smell, cause serious adverse effects on the environment, and harm the health of workers. Therefore, the generated paint mist waste gas needs to be treated before being discharged.

[0003] It is known that the Chinese publicly authorized utility model: (Publication No.: CN214075610U) discloses a paint mist filter box, including a box body. An air inlet is provided on one side of the box body, and an air outlet is provided on the other side. A first filtering structure and a second filtering structure are provided in the box body. The first filtering structure and the second filtering structure have the same composition, and both include an upper roller, a lower roller and a filter screen. The two ends of the upper roller and the lower roller are fixedly connected to the box body. The upper roller is driven by a motor through a transmission structure. The filter screen is connected end to end and suspended on the upper roller and the lower roller, so that a double-layer filter screen screen is formed between the upper roller and the lower roller. A spray head is provided in the middle space of the double-layer filter screen screen. The spray head is connected to a shunt pipe. One end of the shunt pipe is fixedly connected to the box body, and the other end is connected to one end of the main pipe.

The utility model has the functions of simple structure, low cost, avoiding clogging of the filter cotton and having an automatic cleaning function, etc.

[0004] However, in the implementation of the related technology, it is found that the above-mentioned paint mist filter box has the following problems: In the prior art during use, it is not convenient to detect the air flow of the gas entering the filter box, resulting in difficulty in controlling and accelerating the gas flow rate according to the detected air flow, which easily causes dust in the gas with too slow flow rate to accumulate in the pipeline, thereby reducing the filtration efficiency. Therefore, a DPA paint mist box-type filter box is proposed. Content of the Utility Model
