Mixed gas separation, mass storage, pressure rise and energy storage device and method and utility system

Abstract

The invention belongs to the field of energy storage, and discloses a mixed gas separation, mass storage, pressure rise and energy storage device and a method and a utility system, and a heat exchange pressure equalizer. The separation of mixed gas, the pressure rise, the energy storage, the heat exchange and the conversion of gas and liquid are finished in one device, so that the equipment is simplified, the efficiency is improved, and the heat energy is reduced; the cold energy is lost; the energy storage and the energy release can be separately or synchronously performed, so that the emission of carbon dioxide is reduced; and a nitrogen oxide, a sulfur oxide, heavy metal [pm 2.5] and the like are collected for storage and utilization to change harmful substances to useful substances. The invention discloses a gas (air and smoke) condensation, separation and energy storage power station, a wind-electricity plant air separation and energy storage power station, a photovoltaic power generation plant air separation and energy storage power station, a solar heat power air energy storage power station, a wind-electricity solar heat power complementary air energy storage power station, a nuclear power air separation and energy storage power station, a ire coal combustion biomass power generation plane smoke separation and energy storage power station, a gas power generation smoke separation and energy storage power station and an industrial kiln smoke separation and energy storage power station.

Description

technical field [0001] The invention belongs to the field of energy storage, especially the field of gas condensation separation, energy storage, power generation or power drive. Background technique [0002] Mixed gases such as air; natural gas; gas; oilfield gas; flue gas; coal gas; shale gas; coal-to-hydrogen; natural gas-to-hydrogen; The method and technology, the commonly used condensation separation technology, often consumes more energy and needs energy-saving improvement. [0003] Due to the volatility of wind power and solar power, coal power and nuclear power require energy storage devices due to frequent changes in power loads. Pumped water and livestock power stations are the earliest mature technical solutions adopted by countries all over the world. The power station has high requirements on geological conditions and water quality conditions, and it will occupy a large amount of land and relocate people, so site selection is very difficult. Battery energy sto...

AI Technical Summary

Problems solved by technology

However, there are relatively few qualified rock caves, which limits the promotion of this technology.

Twenty megapascals; thirty megapascals; forty megapascals, high-pressure tank air energy storage technology, liquefied air energy storage technology, supercritical air energy storage technology, still in the experimental or demonstration stage, not yet commercialized or the prospect is unknown

CO2 gas is collected separately, which consumes a lot of energy, and the investment and operation costs are very high

This brings difficulties to the construction of gas and oil power stations in water-scarce areas
