Abstract

The invention discloses an automatic deashing device for a diesel particle catcher. The automatic deashing device comprises a first electric control valve (1), a second electric control valve (3), anash collecting box (4), a third electric control valve (5), a fourth electromagnetic valve (8), a first three-way pipeline (9), a second three-way pipeline (10), a third three-way pipeline (11) and afourth three-way pipeline (12). The first three-way pipeline is connected to the first electric control valve, a first flange (2) and the second electric control valve, and the second three-way pipeline is connected to the fourth electromagnetic valve, a second flange (6) and the third electric control valve; and the third three-way pipeline is connected to the fourth electromagnetic valve and thefirst electric control valve, the third end of the third three-way pipeline is the air inlet end, the fourth three-way pipeline is connected to the second electric control valve, the ash connecting box and the third electric control valve, and the third end of the fourth three-way pipeline is the air outlet end. The automatic deashing device disclosed by the invention can eliminate ash accumulated in a DPF carrier and collect the ash in the ash collecting box automatically, the accuracy of regeneration control is guaranteed, the regeneration cost is saved, and the automatic deashing device isconvenient to use.

Description

technical field [0001] The invention relates to the technical field of post-treatment of diesel engine exhaust, in particular to an automatic ash removal device for a diesel particle trap. Background technique [0002] With the rapid development of the transportation industry, the number of diesel vehicles is increasing, which has brought many conveniences to mankind. However, apart from convenience, its serious exhaust emissions also threaten the human living environment and their own health. [0003] Due to the uniqueness of the diesel engine's combustion method, the combustion products mainly include hydrocarbons (HC), carbon monoxide (CO), soot (C) and nitrogen oxides (NOx). With the increasingly stringent emission regulations, the requirements for the limits of the above-mentioned emissions are becoming more and more stringent. Therefore, in order to meet the requirements of the regulations, the off-machine after-treatment technology has been widely promoted. In order...
