Liquid exhaust pipe cleaner

Abstract

The invention relates to a liquid exhaust pipe purifier. The shell is divided into two closed expansion chambers by an insulating partition perpendicular to the axis of the shell; Said housing is parallel and coaxial, elastic mesh cylinder; The airtight purification ring tube surrounded by said housing, partition and each said mesh cylinder is filled with purification liquid; each said purification ring The barrel communicates with the elastic cooling box; metal air guide pipes are respectively fixed on the air inlet end and the air outlet end, and metal air exchange pipes vertically penetrating through the partition board are fixed on the partition plate; the metal air guide pipe and the metal The ventilation tube is electrically connected to the positive pole of the high-voltage power supply, and the housing is electrically connected to the negative pole of the high-voltage power supply; the purifier has low manufacturing cost and small size, can efficiently purify harmful gases and impurities in the exhaust gas, and has an auxiliary noise reduction function, and It can reduce the temperature of the exhaust gas and prolong the service life of the exhaust pipe.

Description

technical field [0001] The invention relates to an automobile exhaust pipe fitting, in particular to a purifier. Background technique [0002] The purification devices commonly used in automobile exhaust systems mainly include three-way catalytic converters. Its carrier part is a porous ceramic material, and precious metals such as platinum, rhodium, and palladium are coated on its surface; CO, HC and NO in exhaust gas X and other harmful gases are decomposed into CO 2 、H 2 O, N 2 and O 2 and other harmless gases and discharged into the air; this kind of purifier has the following disadvantages: First, it needs to ensure a certain active temperature during use; when the temperature is too low, the catalytic efficiency drops sharply, and when the temperature is too high, it is easy to cause The aging of the catalyst is aggravated, which shortens the service life of the purifier; second, the cost of this purifier is relatively high; third, since the active temperature is ...
