Problems solved by technology

[0002] With the development of society, automobiles have gradually become a necessary means of transportation for every household. However, with the increase in the number of automobiles, the environmental pollution caused by automobile exhaust is becoming more and more serious. The temperature of automobile exhaust is usually very high. The surrounding environment causes heat pollution. Using waste heat recovery devices can reduce pollution and save energy. However, the exhaust heat utilization rate of waste heat recovery devices currently on the market is not very high.

Embodiment 2

[0034] A method for recovering exhaust waste heat of an automobile engine, comprising the exhaust waste heat recovery device of an automobile engine, further comprising the following steps:

[0035] S1: Cold water is installed in the water storage tank 3, and the exhaust gas discharged from the engine enters from one end of the air pipe 4. The filter layer 5 made of activated carbon in the air pipe 4 filters out the solid particles in the exhaust gas, and the air pipe 4 made of a copper tube absorbs the heat energy in the exhaust gas. pass it on;

[0036] S2: The multiple inner grooves 6 on the inner wall surface of the air pipe 4 increase the contact area with the exhaust gas, and the multiple outer grooves 7 on the outer wall surface increase the contact area between the air pipe 4 and the cold water, and a small part of the exhaust gas passes through the air guide pipe 9 from the air outlet 10 is discharged into the elastic air bag 11;

[0037] S3: the elastic airbag 11 ex...

Abstract

The invention discloses an automobile engine exhaust waste heat recoverer and method. The automobile engine exhaust waste heat recoverer comprises a shell, a heat insulation layer is arranged on the inner wall surface of the shell, a water storage tank is arranged on the inner side the heat insulation layer, and a gas pipe is arranged in the water storage tank. A filter layer is disposed at one end of the gas pipe, an inner groove is formed in the inner wall surface of the gas pipe, an outer groove is formed in the outer wall surface of the gas pipe, an opening is formed in the other end of the gas pipe, and a gas guiding tube is disposed at the top of the opening. A gas outlet is formed in one end of the gas guiding pipe, and an elastic gas bag is arranged at one end of the gas outlet. The automobile engine exhaust waste heat recoverer is provided with a gas limiting plate to facilitate filtering of fixed particles in the exhaust gas through the filter layer, the formation of a soot layer on the inner wall surface of the gas pipe to affect the heat conduction is prevented, the elastic gas bag is expanded to push out the gas limiting plate, the cross-sectional area of the gas pipeis reduced, the discharge rate is reduced, the exhaust gas stays in the gas pipe for a longer period of time, and the heat utilization rate of the automobile engine exhaust waste heat recoverer is integrally higher.

Description

technical field [0001] The invention relates to the technical field of vehicle engine tail gas emission purification technology and energy saving and consumption reduction technology, and in particular to a vehicle engine exhaust heat recovery device and method. Background technique [0002] With the development of society, automobiles have gradually become a necessary means of transportation for every household. However, with the increase in the number of automobiles, the environmental pollution caused by automobile exhaust is becoming more and more serious. The temperature of automobile exhaust is usually very high. The surrounding environment causes heat pollution, and the use of waste heat recovery devices can reduce pollution while saving energy. However, the exhaust heat utilization rate of waste heat recovery devices currently on the market is not very high. [0003] Therefore, it is necessary to invent a kind of automobile engine exhaust heat recovery device and meth...
