Problems solved by technology

[0003] The purpose of the present invention is to overcome the heat insulation failure caused by the automatic sinking of the heat insulation board by gravity in the prior art, or the mixing of cold and hot fluids due to contact, which causes the temperature of the inlet fluid of the heating equipment to drop, or the heat storage device cannot be charged and released at the same time. Based on the disadvantages of carrying out other problems, a thermocline heat storage device that can be applied to liquid heat storage is proposed

Abstract

The invention discloses a thermocline heat storage device used for liquid heat storage. The thermocline heat storage device comprises a variable frequency motor (1), a hot fluid inlet (2), a hot fluid inlet valve (3), a heat insulation layer (4), a heat storage tank (5), a screw (6), a heat insulation plate (7), a cold fluid outlet valve (8), a cold fluid outlet (9), a cold fluid inlet (10), a cold fluid inlet valve (11), a screw bearing (12), a heat insulation plate sealing ring (13), a guide rod sealing ring (14), a guide rod (15), a reduction gear (16), a hot fluid outlet valve (17) and a hot fluid outlet (18), wherein the heat insulation layer (4) is arranged out of the heat storage tank (5); the screw (6) is connected with the heat insulation plate (7) through threads; the screw (6) drives the heat insulation plate (7) to move vertically through rotating; the heat storage tank (5) is divided into an upper cavity and a lower cavity through the heat insulation plate (7); and the heat insulation plate sealing ring (13) and the guide rod sealing ring (14) are used for preventing heat storage liquid to flow between the upper cavity and the lower cavity of the heat storage tank (5).

Description

technical field [0001] The invention relates to an energy storage heat supply device, in particular to a thermocline layer heat storage device for liquid heat storage. Background technique [0002] Heat storage technology is of great significance for discontinuous energy applications such as industrial waste heat and renewable energy. Compared with the traditional high-temperature and low-temperature double-body heat storage system, the single-body heat storage system using the thermocline principle has the advantage of lower cost. In order to ensure the inlet temperature of heat-using equipment, measures need to be taken to suppress the mixing and natural convection of high-temperature liquid and low-temperature liquid in the heat storage system. Chinese patent 201110196337.0 proposes a thermocline solar heat storage system with baffles. The outer surface of the heat storage tank is covered with an insulation layer, and there are multiple parallel thin baffles with low th...
