Automobile engine tail gas utilization device

Abstract

The invention relates to an automobile engine tail gas utilization device which comprises an exhaust pipe (8), wherein a heat exchanger (1) is arranged on the exhaust pipe (8) and is connected with the exhaust pipe (8); the heat exchanger (1) is communicated with a working medium storage box (2), a working medium pump (3) and heat dissipaters (4) in sequence through pipelines (9) to form a circulating loop; a dust fall device is arranged between the exhaust pipe (8) and the heat exchanger (1) and is communicated with a water pump (14), a filter (12) and the working medium storage box (2) through pipelines to form a circulating loop. By the technical scheme, heating in a compartment is realized by full use of waste heat in automobile tail gas; under a condition that an engine normally works, useful work of the engine does not need to be consumed, the whole dynamic performance of an automobile is not affected, the usability of the engine is higher, and energy does not need to be consumed; meanwhile, the tail gas is cleaned, and pollution caused by tail gas emission to the environment is alleviated.

Description

technical field [0001] The invention relates to the field of automobile tail gas utilization, in particular to an automobile engine tail gas treatment and utilization device. Background technique [0002] With the continuous increase of the number of automobiles, the amount of exhaust emissions from automobiles has also increased significantly. The temperature of the exhaust gas emitted by automobiles is as high as 600-700°C, which means that a large amount of heat energy is wasted in vain. At the same time, waste heat is discharged into the air, causing thermal pollution to the environment. . The heating air conditioner of the existing automobile mainly uses the engine to do work to obtain heat energy. This kind of air conditioner not only has a relatively complicated structure, but also needs to consume the useful work of the engine. Since the partial power of the engine is used for the air conditioner compressor, the fuel consumption increases and the engine output The r...
