DPF carrier carbon deposition cleaning device

Abstract

The invention provides a DPF carrier carbon deposition cleaning device, and relates to the technical field of engine aftertreatment maintenance. The DPF carrier carbon deposition cleaning device comprises a box body, a partition plate, a heating assembly and a directional air supply assembly, the partition plate, the heating assembly and the directional air supply assembly are arranged in the box body, the interior of the box body is divided into a first cavity and a second cavity by the partition plate, the heating assembly is arranged in the first cavity, and the directional air supply assembly is arranged in the second cavity; and according to the technical scheme that the box body is provided with a pipeline for communicating the first cavity with the second cavity, and the partition plate is provided with a through hole for communicating the first cavity with the second cavity, the DPF carrier carbon deposition cleaning device has the advantages that the carbon deposition removing effect is good, carbon deposition particles are concentrated, and secondary pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of engine post-treatment maintenance, in particular to a DPF-loaded volume carbon cleaning device. Background technique [0002] With the upgrading of diesel engine emission technology, the use of DPF (Diesel Particulate Filter) technology can filter out most of the soot and other PM particles (particulate matter, particulate matter) in the exhaust gas, effectively reducing PM emissions and meeting the National VI emissions regulatory requirements. However, with the increase of the engine running time, the soot accumulation in the DPF also increases, resulting in an increase in the exhaust back pressure, which affects the power and fuel economy of the engine. Therefore, when the soot accumulation reaches a certain quality, it is necessary to Regularly perform active regeneration to restore DPF function.

Problems solved by technology

However, with the increase of the engine running time, the soot accumulation in the DPF also increases, resulting in an increase in the exhaust back pressure, which affects the power and fuel economy of the engine. Therefore, when the soot accumulation reaches a certain quality, it is necessary to Periodic active regeneration to restore DPF function

[0003] In the prior art, there is no good solution for the clogging problem of the DPF carrier in the after-treatment of automobiles.

Generally, the temperature is only increased in the furnace, and then the carbon deposit particles inside the DPF carrier are blown out by hot air flow. The discharge of carbon deposit particles in the air is likely to cause secondary pollution.
