Solar energy photo-thermal engine

Abstract

The invention relates to a solar energy photo-thermal engine. A solar energy thermal collector is utilized for being manufactured into an engine air cylinder structure. Due to vacuum heat insulating, the heat loss is small, most heat can be used for doing work to be converted into kinetic energy, in combination with electromagnetic ejectors, water achieves the atomizing effect, then when encountering a high-temperature cylinder body, the water is fast vaporized and swelled to push a piston to do work externally, a connecting rod drives a crankshaft to operate, in order to increase power, more solar energy air cylinders can be adopted for being coaxial with the crankshaft through the connecting rod, by means of cooperation with an electronic circuit, the water ejecting time sequence, the water ejecting amount and the atomizing effect of each electromagnetic ejector are controlled, the output force effect of each cylinder is maximum, and practicality of the solar energy photo-thermal engine is enhanced.

Description

technical field [0001] The invention relates to a thermal engine, especially a solar photothermal engine. Background technique [0002] At present, solar thermal power stations generally adopt the separation of the heat collecting field and the engine equipment. The high-temperature and high-pressure steam can only be transported to the engine equipment by the steam pipeline, and then generate electricity through the generator. The disadvantage is that the steam pipeline is too long and there is secondary heat loss. And the cost is high, high temperature and high pressure transmission has the risk of explosion; the engine equipment of solar thermal power generation usually uses steam turbine or Stirling engine as the device for converting heat energy into kinetic energy, because the two heat engines are difficult to deal with heat loss, so the heat loss is too high Large, only a small part of heat energy is converted into kinetic energy, so the efficiency of actual applicati...

[0002] At present, solar thermal power stations generally adopt the separation of the heat collecting field and the engine equipment. The high-temperature and high-pressure steam can only be transported to the engine equipment by the steam pipeline, and then generate electricity through the generator. The disadvantage is that the steam pipeline is too long and there is secondary heat loss. And the cost is high, high temperature and high pressure transmission has the risk of explosion; the engine equipment of solar thermal power generation usually uses steam turbine or Stirling engine as the device for converting heat energy into kinetic energy, because the two heat engines are difficult to deal with heat loss, so the heat loss is too high Large, only a small part of heat energy is converted into kinetic energy, so the efficiency of actual application is not high, especially the Stirling engine has a huge requirement on temperature difference, it is difficult to improve its efficiency; moreover, the solar thermal field needs to heat a large amount of water to generate A small amount of high-temperature and high-pressure steam, that is to say, most of the water in the heating is only used for convection and heat conduction, and the steam generation efficiency is not high, which directly affects the performance of the engine
