The invention discloses a continuous power generation device and method utilizing organic working medium pump-free circulation, and belongs to the technical field of medium and low temperature heat source power generation. The device and method are used for converting heat energy of a heat source within the range of 70-400 DEG C into power energy through power circulation. The device is jointly driven by flash evaporation jet force and gravity, and comprises a flash evaporation jet pipe bundle, a magnetic ball movement pipe bundle, a liquid storage tank, a linear power generator unit and a rotary power generator unit. After a low-boiling-point working medium in the flash evaporation jet pipe bundle is heated to boil, a lower magnetic ball plays a role of a check valve, kinetic energy generated by boiling expansion of the working medium drives an upper magnetic ball to cut a linear power generator winding to generate power; and meanwhile, a gas-liquid mixture pushes an impeller to rotate to drive the rotary power generator to generate power. When a low-boiling-point working medium in a heat transfer pipe is heated to be boiled, the boiling injection process is intermittent for a single heat transfer pipe, and the impeller can continuously rotate to generate power for the flash evaporation jet pipe bundle. Compared with a traditional organic Rankine cycle, pump work is saved, theadvantage of being high in efficiency is achieved, and the device and method can be applied to medium-low temperature waste heat power generation.
Description
technical field [0001] The invention belongs to the technical field of medium and low temperature heat source power generation, and in particular relates to a continuous power generation device and method using organic working medium without pump circulation. Background technique [0002] Thermal energy is the most widely used form of energy in the national economy and people's lives. In recent years, many scholars have done a lot of research on the utilization of various medium and low temperature thermal energy. There are many kinds of low-temperature energy sources with a huge total amount, including various industrial waste heat, solar energy, geothermal energy, biomass energy, ocean temperature difference energy and LNG cold energy, etc. With the vigorous advancement of energy conservation and emission reduction, there are relatively mature application technologies for medium and high temperature heat sources, such as industrial waste heat and solar concentrated heat. ...
