In order to fully utilize the heat energy of the exhaust pipe of the engine, the temperature difference power generation elements are arranged to cover the surface of the exhaust pipe of the engine to the maximum extent; the temperature difference power generation elements are connected in series or in parallel according to the requirements of an electric appliance; and the converted electric energy is directly supplied to the electric appliance and stored into an accumulator cell.
Description
Technical field
The present invention relates to a kind of method of engine exhaust pipe differential temperature electricity generating.
Background technology
Fuel oil or the fuel that gas engine consumed can not hundred-percently be converted into mechanical energy, and wherein quite a few emits as high-temperature tail gas, and temperature is up to 200-500 degree centigrade, and this part fuel can not do work and emit is a kind of waste.
Thermo-electric generation is a kind of novel generation mode, utilizes the Sai Beier effect heat energy can be converted into electric energy.This technology has been applied to measure temperature, radiation intensity, spacecraft electric power system.The present invention utilizes the engine exhaust pipe differential temperature electricity generating heat of tail gas can be converted into electric energy.
Summary of the invention
Purpose of the present invention is exactly to utilize thermo-electric generation that the exhaust heat-energy of engine emission is converted into electric energy, realizes the recycling of energy.
The object of the present invention is achieved like this:
The principle of institute of the present invention foundation is: electrons spread, when two kinds of different metallic conductors contact, will take place in the different free electron density differences that metal material had on contact-making surface.The speed of electrons spread relevant with the electron density of two conductors and and the temperature of contact zone be directly proportional.The present invention adopts the higher temperature-difference power generation module element of conversion efficiency of thermoelectric, presses thermo-electric generation size of component welding fixed card on the plane of the exhaust pipe of engine, inlays the thermo-electric generation element in fixed card.For making full use of the heat energy of the exhaust pipe of engine, the setting of thermo-electric generation element is the surface of covering engine blast pipe to greatest extent,, then the electric energy of conversion is directly supplied with electrical appliance or is stored in the storage battery thermo-electric generation element connected in series or parallel connection according to the electrical appliance demand.
This Blast Furnace Top Gas Recovery Turbine Unit (TRT) can be applicable on the exhaust pipe of engine of various discharging high-temperature tail gas such as automobile, tractor, motorcycle, internal combustion engine train, steamer, aircraft.Also can be applicable on the catalytic cleaner in the gas extraction system.
The present invention has the following advantages:
1. the engine exhaust pipe differential temperature electricity generating system adopts the solid-state thermo-electric generation element, does not have mechanical motion parts, and installation is simple, firm, stable working state.
2. engine exhaust pipe differential temperature electricity generating noiselessness is pollution-free, belongs to clean energy resource.
3. utilizing the motor exhaust generating is the effective measures of energy circulation utilization, energy-saving and emission-reduction, has stronger practical value.
Description of drawings:
Accompanying drawing is the structure chart of engine exhaust pipe differential temperature electricity generating.
Embodiment;
Embodiment according to structure shown in the drawings, according to thermo-electric generation size of component welding fixed card, inlays the thermo-electric generation element in fixed card on the plane of the exhaust pipe of engine.For making full use of the heat energy of the exhaust pipe of engine, the setting of thermo-electric generation element is the surface of covering engine blast pipe to greatest extent.When engine moves, the blast pipe surface temperature raises, cause the contact-making surface temperature of thermo-electric generation element to raise, the temperature remains within the normal range and the another side of thermo-electric generation element is because of ingress of air, caused thermo-electric generation element two sides bigger temperature difference to occur thus, temperature difference is ordered about the mobile and generation voltage of thermo-electric generation element internal free electron, makes heat energy change into electric energy.According to the electrical appliance demand, the connection of thermo-electric generation element connected in series can be produced high voltage, the parallel connection of thermo-electric generation element can be produced high electric current.The electric energy that transforms can directly be supplied with electric loading and use, and also can be stored in the storage battery standby.
