The invention discloses a particulate trap capable of improving the regeneration efficiency. The particulate trap capable of improving the regeneration efficiency comprises a shell and a diesel particulate filter (DPF) element arranged in the shell, wherein a tail gas inlet is formed in the front end of the shell; a tail gas outlet is formed in the rear end of the shell; and a spoiler for enablinga tail gas to produce eddy currents is arranged on the tail gas inlet of the shell, and comprises a rotary shaft and multiple blades arranged on the rotary shaft along a circumferential direction. According to the particulate trap capable of improving the regeneration efficiency, the spoiler is arranged on the tail gas inlet, so that the tail gas can produce the eddy currents in different scaleswhen entering so as to fully contact the outer edge of the DPF element, the particulate can be combusted thoroughly, and the regeneration efficiency is greatly improved.
Description
technical field [0001] The invention relates to the technical field of diesel engine tail gas treatment, in particular to a particle trap capable of improving regeneration efficiency. Background technique [0002] The particle catcher is installed in the exhaust system of a diesel vehicle. Its function is to capture particles through a filter device mixed on the surface and inside, and can effectively purify more than 90% of the particles in the exhaust. During the working process of the particulate filter, regeneration is also involved. The regeneration efficiency directly affects the exhaust back pressure of the diesel engine, and affects the power and economy of the engine. [0003] At present, during the regeneration process of particulate traps on the market, due to the influence of factors such as structure and regeneration temperature, the outer edge of the DPF filter element of the particulate trap cannot fully contact with the high-temperature exhaust gas, so that t...
