Pressure-bearing heat accumulation tank capable of containing heat accumulation material

Abstract

The invention provides the technical scheme of a pressure-bearing heat accumulation tank capable of containing a heat accumulation material. According to the scheme, the pressure-bearing heat accumulation tank comprises a heat accumulation tank body, a tower plate, heat accumulation plates, a lower water inlet and outlet pipe and an upper water inlet and outlet pipe. The heat accumulation plates contain the heat accumulation material. According to the pressure-bearing design, the heat accumulation temperature of the heat accumulation tank can be raised to 100 DEG C or above. According to the structure, as the heat accumulation capacity of the heat accumulation material in the heat accumulation plates is dozens of times higher than that of hot water, the heat accumulation capacity can be improved when the temperature of heat accumulation water after the heat accumulation tank bears pressure. Accordingly, the amount of heat accumulation water can be reduced, the number or volume of heat accumulation tanks can be reduced, and then the occupied area and volume of the heat accumulation tanks can be reduced.

Description

[0001] Technical field: [0002] The invention relates to a heat supply device, in particular to a heat storage device for a heat supply system. [0003] Background technique: [0004] In the prior art heating equipment, the heat storage tank is equipped with hot water for heat storage. Due to the limitation of the specific heat of water and the temperature difference, the heat storage capacity is small. In order to meet a certain heat storage capacity, a large amount of hot water is usually used to To meet the needs, a large number of heat storage tanks and a larger floor area are also required. Patent No. 201611033975.X authorized by the Patent Office of the State Intellectual Property Office, including "insulation tank body, hot water inlet and outlet pipes, cold water inlet and outlet pipes, upper detachable water distribution tray and lower detachable water distribution tray, insulation tank body The top of the top is equipped with a safety valve vent and a steam inlet to...
