Background
With the improvement of life quality, automobiles become necessary tools for people to ride instead of walk, and although the automobiles bring convenience to life of people, the exhaust gas discharged by the automobiles causes great pollution to the atmosphere. Automobile exhaust contains carbon monoxide, nitrogen oxide and other solid particles which have adverse effects on human bodies.
The solid suspended particles have complex components and strong adsorption capacity, can adsorb various metal dust, strong carcinogens benzopyrene, pathogenic microorganisms and the like, can enter the lung of a human body along with respiration, and are retained at different parts of a respiratory tract in collision, diffusion, deposition and other modes to cause respiratory system diseases. And when the suspended particles accumulate to a critical concentration, they trigger the formation of malignant tumors. In addition, the suspended particles can directly contact skin and eyes to block hair follicles and sweat glands of the skin, so that dermatitis and eye conjunctivitis are caused, and even cornea injury is caused, so that the solid suspended particles in the automobile exhaust have great harm to human health, and a good particle treatment method for the particles in the automobile, especially the diesel engine automobile industry, does not exist at present.
In addition, with the increasing demands for environmental protection, more and more automobiles are equipped with exhaust gas catalytic converters and oxygen sensor devices, which are installed in the exhaust pipe of an engine to convert three exhaust gas harmful substances, CO, HC and NOx, discharged from the engine into harmless water, carbon dioxide and nitrogen through oxidation-reduction reactions, and thus are also called three-way catalytic converters. However, the three-way catalytic converter has strict requirements on operation, particularly on temperature, which cannot be too high or too low, and if the three-way catalytic converter is not used properly, the three-way catalytic converter can cause early failure and even damage of the catalytic converter.
The three-way catalytic converter has no catalytic capability at normal temperature, the catalyst has oxidation or reduction capability only by heating to a certain temperature, the ignition temperature of the catalytic converter is usually 250-350 ℃, and the normal working temperature is usually 350-700 ℃. However, the catalytic converter generates a large amount of heat during operation, the higher the heat, the higher the oxidation temperature, and when the temperature exceeds 850-.

As shown in fig. 10, the difference between the catalytic converter 1 and the embodiment 1, 2 or 3 is that the catalytic converter 1 in this embodiment includes a housing 11 and a catalyst carrier 12 disposed in the housing 11, a circulation cooling pipe 13 is disposed in the housing 11, the circulation cooling pipe 13 is spirally wound and fixed on the inner wall of the housing 11, and both ends of the circulation cooling pipe 13 extend out of the housing 11; still include the control unit and be connected with the control unit and be used for the water pump that supplies water to recirculated cooling pipe 13, still be equipped with heater 14 in the casing 11 and be used for detecting the temperature sensor 15 of the inside temperature of casing 11, heater 14 and temperature sensor 15 all are connected with the control unit.
The requirement for temperature control in the catalytic converter 1 is strict, and the temperature in the catalytic converter 1 is ensured to be kept within a required range by controlling the temperature in the catalytic converter in real time through the cooperation of the circulating cooling pipe 13, the heating wire 14 and the temperature sensor 15 in the embodiment, so that the catalytic efficiency of the catalyst is greatly improved. During operation, temperature sensor 15 detects the temperature in catalytic converter 1 in real time and sends the temperature signal who detects for the control unit, the control unit carries out the comparison with its interior predetermined temperature value according to the temperature signal who receives, if received temperature is less than when predetermined required temperature, then control heater 14 generates heat and improves the temperature, if when received temperature is higher than predetermined required temperature, then control the water pump and carry out the water-cooling to circulative cooling pipe 13 water supply, reduce the internal temperature of catalytic converter 1, through this kind of mode, can effective control catalytic converter 1 internal temperature, guarantee the high-efficient work of catalyst, and reduce the damage to catalytic converter 1 itself.
In summary, the above-mentioned embodiments are only preferred embodiments of the present invention, and all equivalent changes and modifications made in the claims of the present invention should be covered by the claims of the present invention.
