Waste gas filtering device

Abstract

The invention belongs to the technical field of waste gas filtering, and particularly relates to a waste gas filtering device. A blast blowing exhaust fan is arranged in a position of a gas inlet; waste gas is sucked into the gas suction pipeline through the blast blowing exhaust fan and is conveyed to a primary filtering chamber; the gas inlet speed is improved; the waste gas high passing quantity is reached; the waste gas filtering efficiency is improved; through the active carbon adsorption in a filtering screen, large particle substances in the waste gas are adsorbed and filtered; after the filtering, the waste gas is exhausted; water in a water box is conveyed to a water spraying pipe after being pressurized through a pressurization pump, and is upwards sprayed to adsorb small particle substances in the waste gas; a rotating spray head is arranged on the top of the water spraying pipe; the rotating spray head rotates at a high speed; the water becomes water mist to be scattered tothe periphery; the sufficient contact with the waste gas can be realized; the adsorption effect is enhanced; the primary filtering effect can be reached; the secondary adsorption sedimentation is performed on the dust particle materials; water in a functional water box is discharged; the discharged water is subjected to waste water treatment; then, secondary circulation use can be performed; theenvironment is protected; no pollutants are generated in the process; the waste gas filtering and purification efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of exhaust gas filtering, and in particular relates to an exhaust gas filtering device. Background technique [0002] Exhaust gas filter belongs to one of the products in the field of industrial environmental protection equipment. In the industrial age, the impact of exhaust gas emissions on the environment is becoming more and more serious, such as automobile exhaust, exhaust gas from boilers, etc. With the transformation of economic growth mode, it is urgent to improve working conditions, pay attention to the health of workers, and put forward new requirements for environmental protection. After organic waste gas enters the human body through the respiratory tract and skin, it can cause temporary or permanent damage to human respiratory, blood, liver and other systems and organs, especially polycyclic aromatic hydrocarbons can directly cause cancer in the human body. In addition to causing direct air pol...
