: The invention relates to the use of secondary energy resus and can be used in heat and power, chemical, petroleum and other industries of the national economy.

The purpose of the invention is to increase the efficiency of heat utilization and storage.

I The drawing shows the system of heat recovery and storage of heat, i The system of utilization and storage of heat does not contain successively; heat exchangers 1 and 2 connected along the gas flow with the inlet, outlet nozzles 3-6 of the heat transfer medium and located between them, adsorbing I nozzle 7, the last heat exchanger 2 along the I gas of the inlet and outlet nozzles 5 and 6 connected to I consumer 8 Heat. In the system, the heat accumulator 9, connected to the outlet branch pipe 6- I of the last one along the gases of the heat exchanger I, is installed to the heat consumer 8 and out; the inlet pipe 4 of the first along the way: the gases of the heat exchanger 1 connected I in turn with its inlet pipe I com 3 to the inlet and outlet pipe; chambers 4 and 6 of heat exchanger 2, both heat exchangers I and 2 being connected in the heat transfer medium in a countercurrent circuit with respect to the gas flow. On pipelines connecting the inlet and I outlets 5 and 6 with the inlet; pipe 3 and battery 9 is set; Control valves are 10-12. A valve 14 is also installed on the bypass line 13. At the exit of the latter along the gas path, the heat exchanger 2 in the I5 gas duct are fitted with separators 16, and in the lower part there is a sump 17.

After reaching a satisfactory adsorption, the adsorption of the tank 7 through water vapor re regeneration mode. To do this, valves 10 and 12 are turned on, and the valve is opened, resulting in a twisted coolant circulating a circuit in which heat 1 and 2 are connected, followed by this heated heat transfer fluid in the heat exchanger using two products of desorption vapors and a regenerating flow. Then the heat sinks to the heat exchanger 1, it is additionally heated — and p to the battery 9, and steam-gas is fed to the regeneration of the naspy layer of the nozzle 7. The condensate forming the heat exchanger 2 when cooled and absorbed from the nozzle 7 is separated from the gases in the separator 16, collecting and used in various processes like

The heat recovery and storage system works in the following way,

The heated vapor-gas stream, for example, combustion products, is directed to heat exchanger 1, where it is cooled by a circulating intermediate heat carrier. Then, the cooled gas-vapor stream is fed to the adsorbing unit nozzle 7, where moisture is adsorbed on the macroporous surface of the zeolite with the release of heat, resulting in the moisture content of the vapor-gas stream

The dried and heated gas streams are sent to the heat exchanger 2, where it is cooled by a heated coolant and through the duct 15 and the separator 16 is vented to the atmosphere or used for technological needs, for example, during the drying process. In this mode of adsorption of water vapor from the vapor-gas flow, the heating εm2 of coolant is directed to heat exchangers 1 and 2 in two parallel ways. When this control valves 10, 12, 19 are installed in the open position. When the system is in the heat accumulation mode, the valve 19 is closed and the valve 14 is opened. After reaching the state of dynamic saturation of the adsorbing nozzle 7, the water vapor is transferred to the regeneration mode. To do this, close the valves 10 and 12, and the valve 11 otkryshayut, resulting in a heated coolant circulates in a circuit in which the heat exchangers 1 and 2 are connected in series. In this case, the heated coolant is heated in the heat exchanger 2 by condensing water vapor desorption products and a regenerating vapor-gas stream.
