Motor vehicle tail gas degradation treatment equipment

Abstract

The invention relates to the technical field of automobile tail gas treatment, in particular to motor vehicle tail gas degradation treatment equipment which comprises an outer pipe and an inner pipe, the inner pipe is connected with a circular pipe connector, the outer pipe is rotationally connected with a first rotating shaft and a second rotating shaft, the first rotating shaft is connected with rotating fan blades, the rotating fan blades are connected with heat conduction pieces, and the first rotating shaft is connected with a first gear; the second rotating shaft is connected with eccentric discs and a second gear, the second gear is meshed with the first gear, the inner side of the inner pipe is connected with a buffer cylinder, the bottom of the buffer cylinder is connected with a first spring, the free end of the first spring is connected with a pressing plate, and the pressing plate is in abutting connection with the two eccentric discs; by the adoption of the technical scheme, the spraying amount of urea liquid can be changed in real time along with the exhaust speed of tail gas, meanwhile, the time for the tail gas to pass through the catalytic reduction device can meet the time needed by a catalytic reduction reaction, and the cleaning effect of the tail gas is enhanced.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust gas treatment, in particular to a vehicle exhaust gas degradation treatment device. Background technique [0002] At present, with the progress of the times, automobiles have become an indispensable part of people's lives. However, although the development of the automobile industry has brought great benefits to human beings, it has also polluted our living environment. Harmful gases, thus causing greater pollution to the atmosphere, especially in large and medium-sized cities, the number of car ownership is on a linear upward trend, and the emission of automobile exhaust has caused great harm to the health of urban residents, which is the main source of air pollution in modern cities. The main source is that in order to solve the above problem, various automobile exhaust gas treatment devices are operated. The principle of the existing exhaust gas treatment devices is mostly the use of...
