Abstract

The invention discloses a high-temperature regeneration device of a particle trapping device. The high-temperature regeneration device of the particle trapping device comprises a furnace body with a heating cavity, a heating assembly located in the heating cavity, a gas supply assembly for supplying gas to the heating cavity and a control unit for controlling the gas supply of the gas supply assembly, wherein the heating cavity is provided with a gas inlet and a gas outlet; the gas supply assembly communicates with the gas inlet; a waste gas purification device is arranged at the gas outlet; the waste gas purification device comprises an oxygen supply assembly located outside the furnace body and a preheating pipeline; one end of the preheating pipeline communicates with the oxygen supply assembly; the other end of the preheating pipeline extends into the heating cavity and extends to the gas outlet; and the gas outlet is provided with an ignition device. By arranging the waste gas treatment device, oxygen is mixed with waste gas generated by the heating cavity, and then the mixture is ignited again through the ignition device, so that harmful gas, especially CO, in the waste gas is fully combusted, the waste gas is further purified, and the cleanliness of exhausted gas is improved.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a high-temperature regeneration device for a particle trapping device. Background technique [0002] With the continuous upgrading of my country's vehicle exhaust emission regulations, in order to meet the PM (particulate matter) emission standards in diesel vehicle exhaust emissions, more and more diesel engines and vehicles have begun to install particulate capture devices (Diesel Particulate Filter). Purification of PM in exhaust gas. Particulate Trap A ceramic filter installed in the exhaust system of a diesel engine that traps particulate emissions before they enter the atmosphere. Most of the particulate matter (soot) in diesel engine exhaust pollutants is composed of tiny particles of carbon or carbide (size less than 4-20 μm), and the particulate trapping device can filter more than 90% of these particulate matter. [0003] With the continuous popularization ...
