METHOD FOR OPERATION OF THE WATER TREATMENT PLANT AS PART OF THE COMPRESSED-AIR POWER STATION HEAT RECOVERY CIRCUIT Russian patent published in 2023 - IPC C02F1/42 F01K25/06 F01K3/00 

FIELD: power industry.

SUBSTANCE: invention is intended for generating electricity when covering a variable load of electricity consumption based on the technology of air energy storage and can be used in thermal power engineering. The objective of the claimed technical solution is to develop a method for operation of the water treatment plant as part of the compressed-air power station’s heat recovery circuit, which leads to the rejection of the purchase of table salt for the regeneration of softening filters, which generally leads to a reduction in the operating costs of this water treatment plant and an increase in the efficiency of the compressed-air power station. The essence of the claimed invention lies in the fact that the flow of salt brine from the ground tank of the constant pressure air accumulator is directed to regenerate the ion exchange resin of the softening filter of the water treatment plant, which is part of the compressed-air power station’s heat recovery circuit, while the flow of purchased table salt is excluded for the regeneration of the ion exchange resin of the softening filter of the water treatment plant, which is part of the compressed-air power station’s heat recovery circuit.

EFFECT: result is achieved due to the fact that the regeneration of the ion exchange resin of the softening filter of the water treatment plant, which is part of the compressed-air power station’s heat recovery circuit, is carried out when salt brine is supplied from the ground tank, which is part of the constant pressure air accumulator, where it is diluted with source water to the desired concentration and, further, is supplied for the regeneration of the ion exchange resin of the softening filter of the water treatment plant that is part of the compressed-air power station’s heat recovery circuit.
