Magnetofluid multi-pass three-way catalyst cleaning system and cleaning method thereof

Abstract

The invention discloses a magnetofluid multi-pass three-way catalyst cleaning system, which comprises a cleaning machine and a permanent magnet rotary machine. The cleaning machine comprises a shell,and a steam generator, an air compressor, a cleaning fluid storage tank and a magnetofluid cleaning fluid storage tank arranged in the shell; the permanent magnet rotary machine is formed by a motor and permanent magnets arranged on the motor; a rotary shaft is connected onto the motor; and a plurality of lamellar permanent magnets are arranged on the rotary shaft. The invention further disclosesa method for cleaning a three-way catalyst through a magnetofluid. The method comprises four steps of cleaning through steam, cleaning through a cleaning fluid, cleaning through a magnetofluid cleaning fluid, and cleaning through steam. According to the system and the method provided by the invention, through multi-pass cleaning the three-way catalyst, stains can be specifically cleaned step by step, the operation can be carried out easily without complex processes, an automobile has no need to be started during a cleaning process, no exhaust gas is emitted, no oil consumption is lost, and stubborn carbon deposits in the three-way catalyst can be thoroughly cleaned.

Description

technical field [0001] The invention relates to the field of cleaning devices, in particular to a magnetic fluid multi-flow three-way catalytic converter cleaning system and a cleaning method thereof. technical background [0002] With the continuous increase of the number of motor vehicles, automobile exhaust in many cities has become the main source of air pollution. Carbon monoxide, hydrocarbons, nitrogen oxides, sulfur dioxide, lead, carbon particles and other impurity dust and other substances emitted by automobile exhaust have become the chief culprit for the aggravation of PM2.5 pollution and frequent occurrence of atmospheric smog in my country in recent years. The entire ecological environment is extremely harmful. The three-way catalytic converter is the most important external exhaust gas purification device installed in the exhaust system of the automobile. It can convert harmful gases such as CO, HC, and NOx emitted from the exhaust gas of the automobile into ha...

AI Technical Summary

Problems solved by technology

In China, low fuel grades, poor oil quality, high sulfur content in fuel, serious road congestion, and bad driving habits of drivers have caused chemical poisoning of three-way catalytic converters due to chemical complexes of sulfur, phosphorus, and carbon monoxide. , leading to the failure of the three-way catalyst

[0003] The catalyst of the three-way catalytic converter is generally made of rare metals such as platinum, rhodium, and palladium, and the price is very expensive.

Patent CN205926481 discloses a three-way catalytic converter cleaning machine, which includes a cleaning liquid storage tank and a gas generating device. The cleaning process is to spray the cleaning liquid into the three-way catalytic converter under the action of gas pressure. The cleaning process is simple, but only one The cleaning process is not thorough enough to clean the carbon deposit deep inside the three-way catalytic converter.
