Description

Technical Field

[0001] The utility model relates to the technical field of industry-related aspects, in particular to environmental protection equipment for removing dust from industrial waste gas. Background Art

[0002] Industry is a social material production department that exploits natural resources and processes various raw materials. Industry is the product of the development of social division of labor. After several development stages such as handicrafts and machinery industry, it is the main component of the secondary industry and is divided into light industry and heavy industry. In 2014, China's total industrial output value reached 4 trillion US dollars, surpassing the United States to become the world's number one industrial producer. A large amount of waste gas will be emitted in the process of industrial processing, so dust removal equipment is needed when the waste gas needs to be dusted. In recent years, with the rapid development of the economy, the number of metallurgical steelmaking electric furnaces and boilers fueled by raw coal has increased a lot. The atmospheric pollutants emitted by these furnaces have caused great harm to the surrounding environment, so the technology of removing particulate matter from dust-containing gases to reduce their emissions into the atmosphere is becoming more and more important.

The utility model can be set through the locking mechanism. The operator only needs to squeeze the top of the pressing block and make the squeezing pad disengage from the inside of the movable cover to release the fixation of the movable cover, thereby achieving the effect of easy opening of the movable cover. However, during the use of the environmental protection device for dust removal, if the dust removal equipment is used for a long time, a lot of dust will accumulate inside, thereby affecting the dust removal effect. Therefore, it is necessary to clean the inside of the dust removal device regularly. The above text only describes how to release the fixation of the movable cover, and does not say what the role of releasing the fixation of the movable cover is, nor does it explain how to disassemble and clean the dust collector inside the dust removal equipment, etc. Therefore, it is necessary to propose an environmental protection device for industrial waste gas dust removal.
