Description
Technical field
The present invention relates to a kind of automobile engine tail gas recycle device.
Background technique
The existing warm air air-conditioning that is used on the automobile mainly contains two kinds: a kind of is the warm air air-conditioning that utilizes motor to do work to obtain heat energy, this air conditioner structure complexity, and the useful work that needs consumption of engine, because the part power of motor is used for air condition compressor, make oil consumption increase, engine output reduces, thereby cause the configuration aspect of power source to produce some problems, operation of air conditioner makes automobile integral power decreased performance, particularly evident in some automobiles with small output volumn, in addition, the working medium of air-conditioning is in case leak, can work the mischief to environment, cause greenhouse effect; Another kind is the warm air air-conditioning of independent fuel oil, this air conditioner structure complexity, and need to consume extra fuel, waste energy, and products of combustion has pollution to environment.
At present, along with the continuous increase of automobile quantity, huge motor vehicle exhaust emission amount means huge energy dissipation, can reach 600 ℃～700 ℃ because the exhaust temperature of motor vehicle emission is the highest, and therefore the tail gas used heat that enters in the atmosphere is surprising completely.In addition, waste heat discharge also can cause thermo-pollution to environment in atmosphere.
So existing technology has the following disadvantages: the exhaust temperature height, waste energy, befouling environment.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes on the prior art, provides that a kind of exhaust temperature is low, the automobile engine tail gas recycle device of energy saving, protection environment.
The technical solution adopted in the present invention is: the present invention includes motor, waste pipe, offgas duct, baffler, it also comprises heat exchanger, water tank, hot water pump, at least one radiator, safety valve, the hot side of described heat exchanger is connected with described outlet pipe, described offgas duct respectively, by hot water pipe's composition circulation loop that is connected, described safety valve is arranged on the described hot water pipe successively for the cold side of described heat exchanger, described water tank, described hot water pump, described radiator.
The present invention also comprises filter, and described filter inserts the described outlet pipe between described heat exchanger and the described motor.
Described heat exchanger is plate type heat exchanger or tubular heat exchanger.
Each described radiator parallel connection.
The invention has the beneficial effects as follows: owing to the present invention includes heat exchanger, water tank, hot water pump, at least one radiator, safety valve, the hot side of described heat exchanger respectively with described outlet pipe, described offgas duct is connected, the cold side of described heat exchanger, described water tank, described hot water pump, described radiator is successively by hot water pipe's composition circulation loop that is connected, described safety valve is arranged on the described hot water pipe, after starting described hot water pump, water in the described water tank circulates in described hot water pipe, carrying out heat exchange with the high-temperature tail gas of motor discharge when the described heat exchanger, circulating water temperature is constantly raise, during through described radiator, high temperature circulation water dispels the heat by described radiator, be heat supply in the car, temperature reduces after high-temperature tail gas and the circulating water heat exchange, then through described offgas duct, be discharged in the atmosphere behind the described baffler, alleviated thermo-pollution to environment, in to car in the process of heat supply, the useful work that does not need consumption of engine, therefore save fuel oil, can not cause automobile integral power performance decrease yet, the problem that is short of power of having avoided automobile to occur owing to turning on the aircondition, in addition, the heat supply heating does not need environment is had the working medium of harm hidden danger in the car, the heat-transfer working medium that uses is water, do not pollute the environment, meet the current energy, the general trend of harmonious development, the energy crisis of especially present domestic anxiety and environmental issue, alleviated harm to environment, greenhouse effect have been reduced, simultaneously, the heat supply heating does not also need to consume extra fuel in the car, energy saving, and, the present invention can reequip on the basis of existing outlet pipe, install, maintenance, convenient disassembly is so the present invention is simple in structure, exhaust temperature is low, energy saving, the protection environment;
Because the present invention also comprises filter; described filter inserts the described outlet pipe between described heat exchanger and the described motor; described filter can be adorned water when not warming oneself; can also place other adsorbents such as active carbon, flocculating agent; be used for absorbing the refuses such as solid particle, carbon dioxide, water-soluble gas of tail gas, also can reduce the exhaust emissions temperature simultaneously, when not needing to warm oneself, also can alleviate thermo-pollution environment; so exhaust temperature of the present invention is low, the protection environment.
