Air circularly filtering device

Abstract

The invention relates to an air circularly filtering device. The air circularly filtering device comprises a shell, an air inlet and an air outlet, wherein the air outlet is formed in the upper end of the shell; the air inlet is formed in the left end of the shell; a filtering net is arranged in the shell, and is arranged above the air inlet; baffle plates are arranged above the filtering net, and are staggered on the inner side wall of the shell; a waste material collecting box is arranged at the lower end of the shell, and is arranged below the air inlet; a first fixing block is arranged at the left end of the waste material collecting box; a first fixing groove corresponding to the fist fixing block is formed in the lower half section of the side wall of the shell; elastic brackets are arranged at the upper end and the lower end of the right side of the waste material collecting box; second fixing blocks are arranged on the elastic brackets; second fixing grooves corresponding to the second fixing blocks are formed in the lower half section of the side wall of the shell. After the filtering net in the air circularly filtering device filters air for the first time, the air flows through the staggered baffle plates, and adsorbing blocks on the baffle plates adsorb harmful substances in the air, so that the air filtering efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of environmental treatment, in particular to an air circulation filter device. Background technique [0002] Air, the "living gas" that we breathe every day, covers the surface of the earth in layers. It is transparent, colorless and odorless. It is mainly composed of nitrogen and oxygen, and has an important impact on human survival and production. With the development of industry, a large amount of tail gas will be produced in the process of industrial production. The tail gas in industrial production contains a lot of impurities and harmful substances (such as sulfur dioxide, oxygen, nitrous oxide, methane and dust, etc.), which will not only pollute the environment , and the exhaust gas with impurities will have a certain impact on people's health. If the exhaust gas produced is not directly discharged after treatment, it will cause harm to people's health and it is difficult to meet people's living need...

With the development of industry, a large amount of tail gas will be produced in the process of industrial production. The tail gas in industrial production contains a lot of impurities and harmful substances (such as sulfur dioxide, oxygen, nitrous oxide, methane and dust, etc.), which will not only pollute the environment , and the exhaust gas with impurities will have a certain impact on people's health. If the exhaust gas produced is not directly discharged after treatment, it will cause harm to people's bodies and it is difficult to meet people's living needs.
