Purifying method of carbon monoxide in automobile exhaust

Abstract

The invention relates to a purifying method of carbon monoxide in automobile exhaust. The method comprises the steps of obtaining an exhaust pressure value in an exhaust pipe outlet of an automobile engine; detecting the exhaust in an outlet of an automobile exhaust purifier when the exhaust pressure value reaches a preset value; judging if the emission of the carbon monoxide in the automobile exhaust exceeds a threshold value or not according to the detecting result; and if yes, opening a valve of a second automobile purifier, and discharging the automobile exhaust into the second automobile purifier for carbon monoxide treatment, wherein the automobile second purifier is filled with a carbon monoxide absorbing agent. Through the method, if the automobile exhaust is secondarily treated through the exhaust pressure value and the carbon monoxide emission is judged to prevent the exhaust from polluting the environment.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust control, in particular to a method for purifying carbon monoxide in automobile exhaust. Background technique [0002] Usually, when the car is driving on a relatively gentle road, the exhaust gas purifier installed inside the car can usually absorb the harmful gas well at one time, but when the road surface is uneven, such as mountain roads, the car engine needs to output larger power , At this time, the exhaust gas with more harmful gas content will be discharged, and it is difficult for the automobile exhaust gas purifier to absorb the harmful gas in the exhaust gas at once, which will cause environmental pollution. [0003] Moreover, some harmful gases in automobile exhaust can also cause harm to the human body. For example, carbon monoxide in automobile exhaust combines with hemoglobin in the blood 250 times faster than oxygen. Carbon monoxide enters the blood circulation through t...

Problems solved by technology

[0002] Usually, when the car is driving on a relatively gentle road, the exhaust gas purifier installed inside the car can usually absorb the harmful gas well at one time, but when the road surface is uneven, such as mountain roads, the car engine needs to output larger power , At this time, the tail gas with more harmful gas content will be discharged, and it is difficult for the automobile exhaust gas purifier to absorb the harmful gas in the tail gas at once, which will cause environmental pollution

[0003] Moreover, some harmful gases in automobile exhaust can also cause harm to the human body.

For example, carbon monoxide in automobile exhaust combines with hemoglobin in the blood 250 times faster than oxygen. Carbon monoxide enters the blood circulation through the respiratory tract and forms carboxyhemoglobin after affinity with hemoglobin, thereby weakening the function of blood to transport oxygen to various tissues and endangering The central nervous system can cause dysfunction in people's senses, reactions, understanding, memory, etc. In severe cases, it can endanger the blood circulation system and cause life-threatening

Therefore, inhaling even a small amount of carbon monoxide may cause terrible hypoxic damage to people
