Tail gas treatment system

Abstract

The invention discloses a tail gas treatment system which comprises a secondary combustion device, a smoke adsorption device, an afterheat utilization device, a first-stage exhaust gas recovery device, a second-stage exhaust gas recovery device, a washing solution device and a vapor adsorption device which are sequentially connected. By using the tail gas treatment system, heat in an exhaust gas can be effectively utilized, combustion and use of electric energy or non-regenerated energy are reduced, the environment is protected, and meanwhile, smoke and an acid gas in the exhaust gas can be effectively eliminated, so that the tail gas reaches the emission standard and is discharged.

Description

technical field [0001] The invention relates to a tail gas treatment system. Background technique [0002] Both flue gas and tail gas are combustion products, and there are a lot of smoke, dust, carbon monoxide, carbon dioxide, nitrogen dioxide, sulfur dioxide and other gases in both the flue gas and tail gas. If these gases are directly discharged into the air, they will harm the environment and The weight of the air causes serious pollution, causing a large amount of acid rain to fall. The existing way to treat waste gas is to use high-altitude discharge. This treatment method cannot fundamentally eliminate the air pollution caused by the discharge of waste gas. Contents of the invention [0003] The purpose of the present invention is to provide a zero-pollution waste discharge tail gas treatment system. [0004] The technical solution of the present invention is a tail gas treatment system, which includes a secondary combustion device, a smoke and dust adsorption devi...
