3 results about "Thermal regenerator" patented technology

A method includes using an isochoric displacement through a valved or ducted thermal regenerator to raise the pressure of a vaporized reactant or vaporized reactant constituent as a means to regeneratively capture waste exhaust heat from the product or product constituents of a previous endothermic dissociation of a previous charge of said reactant.

The invention discloses a solar-driven plateau salt lake lithium extraction system and an adjusting method thereof, and belongs to the field of salt lake brine lithium extraction multi-energy complementary technology and self-control adjustment. The lithium extraction system is optimally adjusted by optimally configuring osmotic pressure salinity gradient energy power generation, photovoltaic photo-thermal and hot water and electric energy of a solar heat collector. When illumination is weak at 6-8 o'clock in the morning, a concentrated magnesium solution obtained after adsorption and lithium extraction in the earlier stage serves as an osmotic pressure salinity gradient energy power generation system draw solution, brine is concentrated, power is generated, the solution in the NHHCOs regenerator is heated through electric energy, then the NHHCOs draw solution working mode is switched, and the problem of starting electric energy is solved. Illumination at 8-10 points is enhanced, brine is preheated through photovoltaic photo-thermal heat, hot water in a standby water tank is heated through electric energy, the evaporation-related hot water flow is adjusted according to the water temperature, and the response time is shortened. The illumination intensity is the strongest at 10-15 points, hot water of a solar heat collector provides a heat source for evaporation concentration and crystallization, and photovoltaic photo-thermal electric energy heats a standby water tank. Illumination of 15-18 points is weakened, the standby water tank and the heat storage water tank are combined for energy supply, and the operation time of the designed working condition is prolonged.

This invention discloses a helium phase change cycle cryogenic heat engine system based on the magnetocaloric effect. The system includes a vacuum insulated container, a liquid helium tank, a plunger pump, a cold source replacement countercurrent heat exchanger, a magnetocaloric regenerator assembly, a cryogenic helium temporary storage and transfer pipeline, an ambient heat energy countercurrent heat exchanger, an expander, a pressure stabilizing tank, and at least two cryogenic circulation pumps. The system includes a main working flow path, a low-pressure cold source flow path, and a cryogenic compensation flow path, forming a closed-loop helium working fluid phase change cycle. The beneficial effects of this invention are: (1) the cold and heat sources share the magnetic bed heat exchange channel, improving heat exchange efficiency; (2) the recovered cryogenic helium is used as a supplementary cold source, enabling the magnetocaloric material to work efficiently close to the Curie temperature; (3) the magnetic bed retains cryogenic helium to participate in the tail gas condensation, compensating for insufficient tail gas liquefaction rate; (4) the closed-loop stable operation continuously outputs mechanical energy and / or electrical energy. The superconducting magnetic source cooling can be replaced by other cryogenic liquids through heat exchange, thereby reducing the amount of liquid helium used.
