Description

A kind of motor exhaust generator

Technical field

The utility model relates to a kind of device that utilizes the engine exhaust heat generating.

Background technique

At present, accounting for fuel oil total energy engine exhaust heat over half wastes substantially, similar techniques has outlet pipe directly to pass boiler, and heat exchange efficiency is low, promotes the steamer generating with boiler, its boiler and steamer are all very heavy, be not suitable for vehicle-mountedly, steamer not only weight, volume is very big, and extremely low with the low power efficient of exhaust heat-energy, therefore, this kind technology can't be applied so far.Oil electric mixed dynamic automobile batteries quantity is big, thereby the cost height, and it is short working time to fill once electricity, and the duration of charge is long, and charging place difficulty is looked for, the waste electric energy.

Summary of the invention

The technical problem that the utility model solves is:

Make full use of the engine exhaust heat generating, the engine exhaust heat that wastes is utilized.The present technique enmgine exhaust is received on the tail gas heat exchanger, very long heat exchanger coiled pipe is arranged in the tail gas heat exchanger, and from the tail gas heat exchanger engine exhaust pipe that comes out just to enter, structure unlike the prior art, the heat exchange efficiency height has solved the low problem of prior art heat exchange efficiency.Solved prior art weight, very big, the inefficient problem of volume, driven the mode of generator with micro turbine generator or pneumatic motor, weight, volume are little, and the efficient height is fit to vehicle-mounted.Present technique is used for the oil electric mixed dynamic automobile, the short time interval that can be in operation often charges, as long as engine start just can charge the battery, basically can realize self charging, need not plug-in outward charging modes, use exhaust heat-energy, do not increase fuel consumption, it is long to have solved the duration of charge, and charging place difficulty is looked for problem, the waste electric energy problem that waits charging difficult, has solved the problem of filling once electricity weak point working time.The present technique charging interval time is short, does not need the battery of big quantity, thereby has solved the high problem of hybrid power automobile battery cost.

The technical solution of the utility model is:

The tail gas coil pipe is fixed in the tail gas heat exchanger, end entrance and enmgine exhaust join under the tail gas coil pipe, the outlet of tail gas coil pipe upper end is joined with outlet pipe, tail gas heat exchanger bottom and intake pipe join, intake pipe and high-pressure water pump join, waste pipe branch is arranged on the intake pipe, and pressure exhaust valve and steam exhaust pipe are arranged at tail gas heat exchanger top, and a kind of is that tail gas heat exchanger is joined by steam tube and micro turbine generator.Another kind is that tail gas heat exchanger is joined by steam tube and pneumatic motor, and pneumatic motor joins by pto and generator shaft.The pressure exhaust valve can surpass the certain pressure exhaust and exhaust during water filling in the tail gas heat exchanger.Tail gas enters in the tail gas coil pipe, after the heating of the water around the tail gas coil pipe, flows out the tail gas coil pipe and enters engine exhaust pipe.Water in the tail gas heat exchanger absorbs exhaust gas heat and produces high-pressure water vapor, a kind of is that high-pressure water vapor enters acting generating in the micro turbine generator by steam tube, another kind is that high-pressure water vapor enters pneumatic motor by steam tube, promote the pneumatic motor running and drive generator for electricity generation, the electricity that sends can charge the battery or promote motor and produce power.Tail gas heat exchanger, steam tube, pneumatic motor etc. need the part of insulation, and skin will add the insulation layer.

The good effect of this model utility:

Engine exhaust heat is utilized, and has improved whole efficiency.Provide weight, volume little, the motor exhaust generator that efficient is high is fit to vehicle-mounted.Present technique is used for the oil electric mixed dynamic automobile, the short time interval that can be in operation often charges, basically can realize self charging, need not plug-in outward charging modes, use exhaust heat-energy, do not increase fuel consumption, because the charging interval time is short, do not need the battery of big quantity, thereby reduced the battery cost of hybrid vehicle.
