Abstract

The invention discloses a coagulation device and a vehicle exhaust emission system, and relates to the technical field of vehicle exhaust treatment. The coagulation device comprises a shell and at least one coagulation unit. The shell is provided with a wind inlet and a wind outlet, and ducts communicating with the wind inlet and the wind outlet are formed. All the coagulation units are arranged in the ducts. Each coagulation unit comprises a plurality of sleeves which are sleeved and are in clearance fit with one another, and wind screens, wherein each sleeve extends in the gas flowing direction and is provided with openings in the two ends, a plurality of through holes run through the cylinder wall of each sleeve, channels are formed between the sleeve on the outermost layer and the shell, between every two adjacent sleeves and in the sleeve on the innermost layer correspondingly, wind inlet sides of at least part of channels correspond to the wind inlet, all the channels include thefirst channels and the second channels which are staggered, wind outlet sides of the second channels correspond to the wind outlet, and the wind screens are arranged on the wind outlet sides of the first channels and used for allowing the gas flow in the first channels to enter the second channels through the through holes.

Description

technical field [0001] The invention relates to the technical field of automobile tail gas treatment, in particular to a condensation device and a car tail gas discharge system. Background technique [0002] Automobile emissions are becoming more and more stringent, and the national 6 stage emission will include the number of particles in the emission control. The control of particle number emission has become a difficult problem for automobile emissions, especially for gasoline engines. The control of particles emitted by automobiles in off-machine purification mainly relies on particle traps. However, particle traps have a certain efficiency in capturing particles, especially the particle traps of gasoline engines, which are less efficient, mainly because too small particles cannot be trapped. [0003] The so-called coagulation is the process in which small particles merge into large particles through some mechanisms. The factors that promote particle coagulation include...
