Pipeline type phase change heat reservoir with replaceable heat storage units and working method of pipeline type phase change heat reservoir

Abstract

The invention provides a pipeline type phase change heat reservoir with replaceable heat storage units and a working method of the pipeline type phase change heat reservoir. The pipeline type phase change heat reservoir is used for solving the technical problems that an existing heat reservoir is high in cost, complex in structure and difficult to operate.The heat storage and release device is installed in a conveying pipeline of a heat supply network and comprises a receiving control unit, a heat storage and release unit, a heat storage and release valve assembly and an induction unit, and the receiving control unit is connected with the heat storage and release unit, the heat storage and release valve assembly and the induction unit through control lines.The heat storage and release unit is arranged in the conveying pipeline and connected with the conveying pipeline through a movable connecting assembly.A replaceable phase change heat storage structure is adopted, conversion between the conveying pipeline and the heat storage device is achieved, the idle conveying pipeline is reused, the construction cost is reduced, the heat storage and heat release modes are flexible, network end energy storage peak regulation can be achieved, phase change heat storage is adopted, the heat storage amount is large, in addition, the heat storage device can be directly buried conveniently, the occupied ground space is reduced, and the construction cost is reduced.The placement cost is low.

Description

technical field [0001] The invention relates to the technical field of heat storage equipment, in particular to a pipe-type phase-change heat storage with a replaceable heat storage unit and a working method thereof. Background technique [0002] At present, there are two aspects of energy efficiency in my country. On the one hand, a large amount of industrial waste heat is wasted due to ineffective utilization. On the other hand, many heat users rely on their own boilers to generate heat energy, resulting in a great waste of energy. With the continuous advancement of urban heating and cleaning work in my country, the proportion of natural gas heating has increased year by year, and the heating cost has also shown a trend of increasing year by year. Compared with coal-fired and natural gas heating, industrial waste heat heating has obvious energy-saving benefits, and the cost of heat sources is much lower. The level of recycling technology is difficult to be efficiently uti...
