Description
The utility model relates to a kind of Mechanical-power-producing mechanism that utilizes the natural temperature difference as power.
Along with progress of science and technology, people are except multiple nature such as research water energy, solar energy energy problem, to utilizing thermal gradient energy also to carry out many researchs, particularly high temperature difference generates electricity, provides aspects such as production, life power and refrigeration, heat supply in utilizing geothermal water field, underground hot dry rock, underground hot steam field etc., and technological scheme is ripe.But in the technology of utilizing the low temperature difference as the energy, also do not obtain desirable effect, this mainly is a mechanical structure problem of failing to solve well working medium conversion between high temperature heat source and the low-temperature cold store, the thermal efficiency is too low, so just make between the high low heat about △ T=10-50 ℃ thermal gradient energy also profit do not use, for example many local, summer, the temperature and the phreatic temperature difference had 10-15 ℃, and winter, the temperature difference of ice and snow and water can reach 10-20 ℃.So, this part thermal gradient energy is used, will bring profound significance to solving a part of energy problem.
The purpose of this utility model provide a kind of can utilize in nature in low temperature difference heat, as temperature and water temperature, ice and snow and water temperature, industrial waste heat are the energy, are transformed into the thermal gradient energy motivation of dynamic power, refrigeration, drive machines.
The utility model is realized in following mode: design two heat reservoirs of high low temperature, the inside charges into easy liquefaction working medium such as ammonia, fluorine Lyons, chloroethanes, normal butane, isobutane, carbon dioxide etc., the high temperature heat reservoir is called " heat exchanger ", the low temperature heat reservoir is called " condenser ", heat reservoir is incubated well as far as possible, in order to avoid heat and the extraneous heat of handing over, but if when utilizing the atmospheric temperature and the phreatic temperature difference, then heat exchanger will be open in the atmosphere in a large number or place the pond approaching with temperature, so that two heat reservoirs have the bigger temperature difference.The gas motor is equipped with in gasifying pipe outlet at high temperature heat reservoir (heat exchanger), a rotor pump is equipped with in low temperature heat reservoir (condenser) outlet, the mounting point that also is provided with internally piloted valve heat exchanger and condenser in the Mechanical-power-producing mechanism determines according to environment of living in, as when utilizing underground heat, hot spring or ground water temperature and ground ice and snow thermal gradient energy, heat exchanger is installed in the below of condenser; And when utilizing the temperature difference of the high temperature of underground water and ground of low temperature, heat exchanger is installed in the top of condenser.No matter but rotor pump all should be installed in the extreme lower position of whole thermal gradient energy motivation under what environment, make the working medium after the liquefaction can flow to rotor pump automatically.The working procedure of thermal gradient energy motivation of the present utility model is as follows: inject working medium inside after heat exchanger is evacuated, because temperature is higher in the high temperature heat reservoir, working medium is very easily gasification inside, and formation pressurized gas, this gas leads to the gas motor through changing valve, promote the piston start of gas motor, low-pressure air current behind the workmanship changing valve of flowing through arrives condenser, and under the low temperature of condenser, be condensed into liquid, the working medium of liquefaction flows to rotor pump through changing valve again, rotor pump is delivered to the high temperature heat reservoir after working medium is pressurizeed, to keep normal periodic duty.
The effect of changing valve is to flow to conversion in order to adapt to the working medium that can in time adjust in heat exchanger and the condenser when thermal environment changes, as temperature height in summer, when ground water temperature hangs down, heat exchanger is above condenser, and winter, the ice and snow temperature was lower than ground water temperature, heat exchanger is then below condenser, and in order to keep the normal operation of gas motor and rotor pump, that just need utilize changing valve is used for adjusting Working medium gas and flow direction.
The utility model mainly promotes a kind of device that gas motor (turbine engine) workmanship designs according to the gas pressure that some easy liquefied material such as the above-mentioned ammonia of mentioning, fluorine Lyons, chloroethanes, normal butane, isobutane, carbon dioxide etc. produce when certain temperature gasification, this device can not only use steam field, the hydrothermal field of the higher temperature difference (general more than △ T=50 °), also can be with below △ T=50 °, even the temperature difference heat energy of the different heat sources about △ T=10 ° changes merit into, the promotion machine works.
