Description

Sewage filtering mechanism of particle filter

Technical Field

The utility model belongs to the technical field of particle filters, and particularly relates to a sewage filtering mechanism of a particle filter.

Background

The exhaust system of the diesel vehicle comprises an exhaust pipe and a particle filter arranged in the exhaust pipe, when tail gas in the exhaust pipe passes through the particle filter, particles and greasy dirt in the tail gas are adsorbed and filtered by the particle filter, wherein the particle filter is required to regularly suck hot water into the particle filter through a cleaning mechanism after adsorbing the greasy dirt and the particles for a long time, the hot water dissolves urea crystals in the particle filter and cleans small particles in the particle filter, and then the hot water passing through the particle filter is filtered through a sewage filtering structure.

However, as urea crystals are dissolved in hot water, the sewage filtering mechanism can only filter small particle impurities in sewage, but can not filter urea in the hot water, and urea can be condensed in the sewage filtering mechanism after the hot water is cooled, so that the sewage filtering mechanism is blocked.
