Tail gas purifying device capable of generating electricity through automobile tail gas waste heat temperature difference

Abstract

The invention discloses a tail gas purifying device capable of generating electricity through automobile tail gas waste heat temperature difference. The tail gas purifying device comprises a purifierbox body, a three-way catalyst, a temperature difference electricity generating device, a filter device, an electric precipitation device, a pressure rising and releasing converter and a storage battery. The three-way catalyst is arranged inside the front end of the purifier box body. The temperature difference electricity generating device is arranged outside the purifier box body, is close to the three-way catalyst end and is connected with the storage battery through the pressure rising and releasing converter. The filter device is arranged in the purifier box body and located at the rear end of the temperature difference electricity generating device. The electric precipitation device is located at the rear end inside the purifier box body and connected with the storage battery. The tail gas purifier utilizes the automobile tail gas temperature difference to generate the electricity, the effects of energy saving and emission reduction are achieved, the tail gas utilization efficiency can be effectively improved, meanwhile, exhaust pollution can be reduced, and the environment can be improved.

Description

technical field [0001] The invention belongs to the technical field of automobile tail gas treatment, in particular to an tail gas purifier which utilizes waste heat temperature difference of automobile tail gas to generate electricity. Background technique [0002] With the development of China's automobile industry, the energy consumption of traditional fuel vehicles is increasing day by day, and the energy saving and emission reduction of automobiles and the control of exhaust pollution have always been the focus of attention. At present, most exhaust gas purification devices purify automobile exhaust through adsorption devices, chemical solutions or research on new catalysts. The adsorption device cannot purify the fine particles in the automobile exhaust, and has poor compatibility with the engine exhaust system. The chemical solution is corrosive, it is troublesome to replace, the device takes up a lot of space on the chassis, and the vehicle layout is difficult. Som...
