Intergrated monentum exchager for preventing and treating motor vehicle emission pollution

Abstract

The invention provides a kind of integrate momentum exchanger for preventing the contamination of car tail gas. The character lies in: it is formed by connecting several grades of integral exchangers, each grade of exchanger is made up of receiving pipe, dispersing pipe and negative hole integrated on a mechanism processing flat with the same quantity, and there sets parallel fixed three pressure enhancing pipe of ejection receiving pipe between the first grade and the fourth grade, there sets three parallel pressure adjusting pipe of dispersant pipe between the seventh grade and the ninth grade, one end of the first grade exchanger connects with the air discharging outlet of the car engine, the other end is connected with the current adjusting device and the end tail gas discharging outlet; the invention can eliminate contamination entirely, it also can replace the current discharging and voice resisting system in car.

Description

Technical field [0001] The invention relates to a device for preventing and controlling air pollution, in particular to an integrated momentum exchanger for preventing and controlling motor vehicle tail gas pollution. Background technique [0002] In the prior art, and in order to prevent and control the air pollution caused by motor vehicle exhaust, in 1998, the hydrogen-powered No. 1 prototype vehicle (a fuel cell vehicle powered by hydrogen) was released. The operating principle of the car is the reverse reaction of water electrolysis reaction, through hydrogen (H 2 ) and oxygen (O 2 ) mixed and reacted under controlled conditions to generate the only product: water and electricity, driving the car with a maximum mileage of 400 kilometers and a maximum speed of 140 kilometers per hour. However, the popularization and application of the hydrogen-powered No. 1 fuel cell vehicle is full of difficulties, first of all, it is restricted by the transformation and high sales pr...

Problems solved by technology

If the EFI device fails, such as the oxygen sensor, the control switch, and the air supply valve are damaged, the three-way catalytic converter will be scrapped quickly and lose its function

At the same time, the honeycomb structure of the three-way catalytic purifier is prone to clogging, reaches saturation, and loses its purification effect. It should be replaced with a new purifier frequently, thereby increasing the burden on consumers (generally, the normal use cycle is within 90 days. )

The three-way catalytic converter can only reduce the emission concentration of CO, HC, and NOX in the exhaust of motor vehicles, but it cannot achieve the purpose of completely eradicating the pollution of exhaust from motor vehicles.

The disadvantages are: it affects the dynamic performance of motor vehicles, and it is dangerous when adding gas; the safety is reduced, the supporting and service facilities are not complete, and the scope of promotion is limited; the modification cost is high

However, the control effect on nitrogen hydride (NOX) is not perfect
