Description

technical field [0001] The invention belongs to the field of energy utilization equipment, in particular to a thermal energy power system of a split flow polymerization chamber. Background technique [0002] Energy is an important material basis for the survival and development of human society. Throughout the history of the development of human society, every major progress of human civilization is accompanied by the improvement and replacement of energy. The development and utilization of energy has greatly promoted the development of the world economy and human society. [0003] However, with the continuous development and consumption of energy, non-renewable energy sources such as petroleum, coal mines, and natural gas are gradually reduced, and energy conservation and recycling are gradually being valued. In response to the national energy-saving strategy, more and more enterprises have begun to develop and use energy-saving equipment, and strengthen the utilization o...

Problems solved by technology

[0005] The existing thermal energy utilization equipment that uses gas expansion to do work, under ideal conditions, has the highest rate of thermal energy conversion, which is the Carnot cycle efficiency, that is, 1-T 0 / T 1 , where T 0 is the temperature of the cold source, T 1 It is a high-temperature heat source; but in the actual work process of thermal equipment, on the one hand, due to the gasification process of the circulating working fluid in the gasification device, the actual temperature of its gasification expansion has a large temperature difference with the temperature of the high-temperature heat source, and the actual temperature is lower than the temperature of the high-temperature heat source , whose theoretical T 1 On the other hand, because the actual condensation temperature of the circulating working fluid in the condenser is higher than the temperature of the low-temperature cold source, its theoretical T 0 increase, leading to a decrease in the maximum efficiency of thermal energy; in addition, due to the low absorption rate of the turbine for gas expansion work, its mechanical energy conversion efficiency is low; in addition, the circulating working fluid is prone to impurities, and the circulating working medium consumes a lot of energy

[0006] The specific problems caused by the above-mentioned deviations in existing thermal energy equipment include: 1. The thermal conductivity of the gasification device is poor, and the temperature requirements for high-temperature heat sources are high; 2. The pressure of the gasification device is unstable, and the temperature required for gasification is unstable , when the temperature required for gasification is greater than the temperature of the heat source, the medium cannot be vaporized; when the temperature required for gasification is lower than the temperature of the heat source, the gasification expansion temperature is low, the heat absorption is small, and the net work is small; 3. Condenser The pressure of the internal medium is unstable, and the temperature required for condensation is unstable. When the temperature required for condensation is lower than the temperature of the cold source, condensation cannot be achieved. When the temperature required for condensation is greater than the temperature of the cold source, the temperature after condensation is too low; 4. Condenser The internal condensation is not complete, and the gas-liquid mixed state is prone to appear, resulting in a relatively small gasification and expansion volume of the working fluid in the gasification device; 5. The existing turbine has a relatively small torque, large volume leakage, and low efficiency; 6. The thermal energy conversion efficiency of existing thermal energy equipment is low, and the thermal energy conversion efficiency is generally 10% to 30%; 7. The working medium is easy to deteriorate or appear impurities
