Description

Collection device of DPF cleaning machine

Technical Field

The utility model relates to a granule collection device, in particular to collection device of DPF cleaning machine.

Background

The diesel particulate filter refers to a device, abbreviated as DPF, installed in an exhaust system of a diesel vehicle for reducing Particulate Matter (PM) in exhaust gas by filtering. The DPF is capable of effectively purifying 70% to 90% of the particulates in the exhaust gas, and is one of the most effective and direct methods for purifying diesel particulate matter. Generally, a DPF is attached to an exhaust pipe of a diesel engine, PM particles are adsorbed and filtered by a filter element when exhaust gas passes through the DPF, but PM in the filter element increases with an increase in operation time, so that exhaust back pressure increases, and dynamic performance of the diesel engine is affected. Therefore, removal of PM from the filter element is referred to as regeneration of the DPF.

Wherein, the exhaust gas particle collecting device of DPF plays the subsequent treatment therein, prevents the effect of secondary pollution. A typical exhaust gas particulate collecting apparatus collects PM particulates by using a container or a collecting bag, and then performs a centralized process. However, such a collecting device is relatively primitive, and PM particles are easily adhered to the inner wall of the collecting device, and after a long time use, the effect of collecting particles by the collecting device is increasingly poor, and particle leakage is easily caused when the collecting port is in contact with the outside air, causing secondary pollution.
