Problems solved by technology

[0007] However, the common problems of existing thermal power generation equipment are: a. The temperature requirements for high-temperature heat sources are high, generally above 200°C, and the thermal energy conversion efficiency is low, and the thermal energy conversion efficiency is generally 15% to 35%; b. The heat displacement of the condensing device is large, and the waste of heat energy is large. The condensation speed through the natural condensation method is slow, and the active condensation method (fan air cooling or liquid pump water cooling) requires additional power consumption; c. The turbine is prone to leakage of working fluid Problems; d. Turbine speed is unstable, and it is prone to stuck problems; e. The heat collection effect of the heat collector is not good, and the external waste heat absorption rate is small; f. The gasification temperature of the working medium is unstable, and the condensation effect of the working medium is not good , the working medium is easy to deteriorate or appear impurities; g. The existing equipment is relatively large
[0008] On the other hand, in the process of oilfield exploitation, oil wells will discharge a large amount of methane-containing oilfield waste gas. In order to prevent methane in oil waste gas from being discharged to the outside world, pollute the ozone layer, and prevent excessive accumulation of methane gas near the oilfield exploitation area To cause an explosion, the common practice is to install a waste gas combustion device at the head of the oil well to burn off the combustible gas in the waste gas. This treatment method has caused a large waste of energy
[0009] In response to the above-mentioned energy waste problem, a small number of onshore oil fields will use petroleum gas recovery equipment to recover petroleum gas in oil field waste gas, but the existing petroleum gas recovery equipment requires a large space, complicated installation, and high energy consumption during operation. oil field is hardly applicable
