Integrated momentum exchanger capable of controlling vehicle exhaust pollution

Abstract

The invention provides an integrated momentum exchanger capable of controlling vehicle exhaust pollution. The integrated momentum exchanger is characterized by being formed by connecting multiple stages of integrated exchangers arranged in parallel, wherein an equal number of spray receiving pipes and diffusion pipes which are highly integrated on one mechanical processing plane as well as negative holes are arranged in each stage of exchanger, pressurizing tubes of three spray receiving pipes mounted in parallel are arranged between the first stage of exchanger and the fourth stage of exchanger, pressure adjusting pipes of three diffusion pipes mounted in parallel are arranged between the seventh stage of exchanger and the ninth stage of exchanger, one end of the first stage of exchanger is directly connected with an exhaust port of an engine of a motor vehicle, the other end of the first stage of exchanger is connected the second stage of exchanger, the second stage of exchanger is connected with the third stage of exchanger, the third stage of exchanger is connected with the fourth stage of exchanger, and connection is performed sequentially by the rule until the gas rectifying device is connected with a tail-end exhaust emission port. The pollution removal effect that a symptom of the problem is treated and the causes are treated is realized, and the integrated momentum exchanger can replace an exhausting and silencing system of an existing motor vehicle and becomes the best device and method for fundamentally treating exhaust pollution of the motor vehicle.

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 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 price. ...

AI Technical Summary

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
