Embodiment Construction

[0024] The device of the present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0025] As shown in Figure 1, when the exhaust gas discharged by the internal combustion engine due to incomplete combustion enters the exhaust gas inlet pipe 2 in the exhaust gas purifier housing 1, it passes through the first-stage exhaust gas catalytic oxidation device 3 to obtain preliminary catalytic oxidation. After the purification treatment, the waste gas flows through the second-stage exhaust gas filtration and contact device 4 for large-area contact and filtration to obtain further catalytic oxidation purification treatment. The exhaust gas after the secondary catalytic oxidation purification treatment will produce some turbulent flow, which is installed in the exhaust gas rectification channel 6 between the second-stage exhaust gas filtering contact device 4 and the third-stage exhaust gas purification and separation device 5, aft...

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 treating hydrocarbons, carbon monoxide, nitrogen oxides, and fine dust particles in the exhaust gas discharged from a fuel internal combustion engine due to incomplete combustion. Background technique [0002] At present, at home and abroad, the exhaust gas purification devices and exhaust gas collectors that deal with internal combustion engines that contain hydrocarbons, carbon monoxide, nitrogen oxides, and fine dust particles in the exhaust gas discharged due to incomplete combustion, use metal and non-metal or It is composed of a cylindrical, elliptical and other microporous honeycomb carrier made of ceramics, and a three-way catalyst is coated on its surface. It is used to catalyze the oxidation of hydrocarbons, carbon monoxide, and nitrogen oxides. It is also used for Captures the fine dust particles contained in the exhaust gas emitted by incomplete combustion. However, there is not yet a gr...
