Abstract

The invention discloses an infrared optimal regeneration temperature device for a soot particle filter of a diesel engine. The infrared optimal regeneration temperature device comprises a filtering regeneration bin, connecting pipelines are installed at the two ends of the filtering regeneration bin through connecting structures, each connecting structure comprises a connecting shell, an inner cavity is formed in each connecting shell, threaded holes are formed in the upper side and the lower side of each inner cavity, threaded rods are arranged in the threaded holes, a low-voltage heating element is installed in a filter regeneration cavity and at one side of an air outlet, and an infrared radiator is installed on the filter regeneration cavity. The infrared optimal regeneration temperature device has the advantages that the device is simple in structure and convenient to use, the electric energy utilization rate of infrared radiation heating of soot can be greatly increased, the regeneration time is short, the regeneration process is easy to optimize and control, the indexes of regeneration efficiency, regeneration temperature distribution, regeneration time and regeneration energy consumption are optimized at the same time, and meanwhile, replacement of a filtering device and installation and fixation of the connecting pipelines are facilitated.

Description

technical field [0001] The invention relates to the technical field of filtering soot particulates emitted by diesel engines, in particular to an infrared optimal regeneration temperature device for diesel soot particulate filters. Background technique [0002] At present, domestic and foreign soot particulate filter regeneration technologies include heavy load regeneration, catalytic regeneration, fuel injection combustion regeneration and electric heating regeneration. [0003] Among them, the method of large-load regeneration is relatively simple, but automobile diesel engines rarely work under such working conditions in actual use, and throttling reduces the power and economy of diesel engines to a large extent during the regeneration process, and due to Throttling increases the heat load of the cylinder head, piston, valve and other components, which has an adverse effect on the life of the diesel engine; when the metal oxides, the combustion products of the catalytic r...
