Carrying scraper tail gas purification system

This invention relates to a carry scraper tail gas clean-up system. A connecting pipe is orderly connected to a platinum purifier and a muffler at a tail gas outlet opening of a diesel motor in the carry scraper; after the tail gas is processed the oxidation catalysis with high temperature by the platinum purifier; the carbon monoxide, hydrocarbon and acetaldehyde are converted into harmless carbon dioxide and water, then the tail gas is de-noised through the muffler and at last is discharged to the work site. This invention adopts the platinum purifier and the muffler to purify the diesel motor tail gas, which can not only filtrate the grain in the tail gas, but also has higher converting effect to the CO and hydrocarbon; and this invention is able to effectively control the discharge of harmful composition in the diesel motor tail gas, reduce the work noise through the muffler, improve the underground work environment, ensure the health of the operator, improve the output power of the diesel motor, reduce t
