[0017] Example 1
[0018] Such as figure 1 As shown, the existing diesel particulate trap includes a cavity. The cavity is divided into a plurality of intake air passages 4 and exhaust air passages 5 by a pipe wall 2. One end of the cavity 1 is provided with an air inlet 1, and the cavity The other end of the body 1 is a particle trap plate 6; the middle section of the tube wall 2 is provided with a number of air holes 3; the exhaust gas flow enters the air inlet channel 4 of the particle trap from the air inlet 1 of the cavity, and the gas part After entering the adjacent exhaust channel 5 through the air hole 3 on the pipe wall 2 and flowing out from the air outlet 7, the particulate matter continues to hit the particulate matter catching plate 6 at the bottom of the intake channel 4 due to inertia, thereby being trapped by the particulate matter The plate 6 traps; however, during work, the inevitable part of the particulate matter is adsorbed when passing through the pore 3 du...
