A diesel engine exhaust particulate matter collection device

Abstract

The invention belongs to the field of mechanical design, and particularly relates to a diesel exhaust particle collecting device. The diesel exhaust particle collecting device comprises an air inlet,a connecting channel, a carbon emission V-shaped groove, an exhaust port and a carbon deposition port. The air inlet, the connecting channel, the exhaust port and the carbon deposition port are all cylinders, and the output end of the air inlet and the input end of the carbon deposition port are connected to the input end of the connecting channel of which the output end is connected to the exhaust port through the carbon emission V-shaped groove; the output end of the carbon deposition port is a movable opening, and can be opened for clearing carbon deposition; the carbon emission V-shaped groove is a V-shaped groove body with an included angle of 90 DEG - 120 DEG; and the included angle between the connecting channel and the air inlet is 20 DEG - 30 DEG. According to the diesel exhaust particle collecting device, diesel exhaust particles can be intercepted and collected fully, so that no carbon deposition is formed on the inner wall and the surface of a guide plate under the condition of fully intercepting the particles, and the carbon deposition is gathered to the carbon deposition port through the V-shaped groove, and is easy to clear.

Description

technical field [0001] The invention belongs to the field of mechanical design, and in particular relates to a diesel engine exhaust particle collection device. Background technique [0002] Diesel engines are widely used in construction machinery and agricultural machinery due to their large output torque, economical durability, etc., but their high exhaust particulate matter emissions cannot meet the increasingly stringent emission regulations. [0003] The main component of the particulates emitted by diesel engines is carbon, which can penetrate deep into the lungs and damage the self-purification of various channels in the lungs, thereby causing other compounds to play a carcinogenic role. Many organic substances, including polycyclic aromatic hydrocarbons, are adsorbed on these carbon particles, which have mutagenic and carcinogenic effects to varying degrees. [0004] In addition to being seriously harmful to the human body, it will also cause great pollution to the ...

AI Technical Summary

Problems solved by technology

[0008] The invention provides a diesel engine exhaust particle collection device, which solves the problem that the existing diesel engine exhaust treatment device cannot fully intercept the exhaust particulate matter, and the carbon deposit in the exhaust pipe is serious and difficult to clean.
