Problems solved by technology

At present, the common point of various liquid pressure energy methods is that the permeable membrane is used to convert the liquid pressure energy, but the relatively large resistance characteristics of the permeable membrane itself, the problem of solute reverse osmosis, and compatibility problems greatly restrict the liquid pressure. Practical application of energy law

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a supergravity thermal power device. Background technique [0002] The thermodynamic cycle methods currently used are basically steam pressure methods, that is, high-pressure steam is obtained by high-temperature heat sources, and then high-pressure steam is used to generate power. This method can operate normally when the temperature of the heat source is high, but when it is widely used When the low-grade heat source is less than 80°C, due to the small vapor pressure difference formed, it is affected by shaft seal friction loss, high and low pressure sealing loss, disc friction loss, and hydraulic loss, resulting in a significant reduction in its effective output power and efficiency. . [0003] Another thermodynamic cycle method is the liquid pressure energy method, which converts heat energy into liquid pressure energy to drive the liquid turbine to do work. Its char...
