Abstract

This invention belongs to a waste gas purification equipment of hydrocarbons, carbon monoxide, nitrogen oxides, fine dust particles contained in the waste gases of not entirely internal combustion engine, its characteristics are that, the waste gas through the first-level gas catalytic oxidation device and the second-level gas contacts exhaust filter acquire the purification treatment of twice catalytic oxidation, and then spray sprinkler pre-treat the remained waste gas with the dilute aqueous solution, then through the third catalytic oxidation and the repeat treating of purify separation, the waste gas of hydrocarbons, carbon monoxide, nitrogen oxides treatment rate reached more than 97%, the gas contained dust particles remove more than 99%, thus achieving stability and separation and the effective purification purposes.

Description

Technical field [0001] The invention belongs to an exhaust gas purifier for processing fuel-burning internal combustion engines, and the exhaust gas discharged due to incomplete combustion contains hydrocarbons, carbon monoxide, nitrogen oxides, and fine dust particles for purification treatment. Background technique [0002] At present, the exhaust gas purification devices and exhaust gas traps that contain hydrocarbons, carbon monoxide, nitrogen oxides, and fine dust particles in the exhaust gas from internal combustion engines processed at home and abroad due to incomplete combustion use metal and non-metal or It is composed of a cylindrical, elliptical, and other microporous honeycomb carrier made of a ceramic body, and is coated with a three-way catalyst on its surface. It is used to catalyze the oxidation of hydrocarbons, carbon monoxide, and nitrogen oxides, and at the same time. The exhaust gas discharged from the trap of incomplete combustion contains fine dust particles...
