Energy storage peak regulation tank heat storage system and heat storage method

Abstract

The invention relates to an energy storage peak regulation tank heat storage system and a heat storage method. Currently, the contradiction between high heating load and off-peak load regulation of apower grid at night in northern China is prominent, and a system capable of conveying heat energy on time according to quantity and temporarily storing the heat energy when a unit is in high load is urgently required. The system comprises an energy storage tank (9), a high-temperature outlet of the energy storage tank is connected with an expansion joint A (8), a shut-off valve D (7) and a flow meter A (6) in sequence, the flow meter A is connected with an adjusting valve (4) through a shut-off valve C (5), the adjusting valve is connected with a shut-off valve B (3) and a shut-off valve A (2)in sequence, the shut-off valve A is connected with a heat supply high-temperature water main pipe (1), a low-temperature inlet of the energy storage tank is connected with an expansion joint C (13),a shut-off valve F (14) and a flow meter B (15) in sequence, and the flow meter B is separately connected with a first energy storage booster pump (16), a second energy storage booster pump (17) anda third energy storage booster pump (18) through the shut-off valves. The system is used for the energy storage and peak regulation tank heat storage systems.

Description

technical field [0001] The invention relates to the technical field of high-efficiency energy utilization of urban heating units and peak-shaving and valley-filling, and in particular to an energy storage peak-shaving tank heat storage system and a heat storage method. Background technique [0002] The heat storage system of the energy storage peak shaving tank is an important component of the energy storage peak shaving system, which has a great impact on the overall performance of the energy storage peak shaving system. With the development of the economy and the improvement of people's living standards, the high load and The contradiction of power grid peak shaving is also becoming more and more prominent. There is an urgent need for a system that can transmit heat energy on time and in accordance with the amount and store it temporarily when the unit is under high load. At this stage, it is common to use the phase change latent heat of phase change materials to realize he...

Problems solved by technology

[0003] The object of the present invention is to provide a heat storage system and heat storage method of an energy storage peak regulation tank. The structure and method temporarily store the high temperature water for heating when the load of the heating unit is relatively high and the demand for heat users is relatively low. , as a supplementary heat source when the unit peaks load at night, it solves the problem that the high-temperature water for heating is injected into the energy storage tank in a timely manner and stored, and is used as a supplementary heat source for heating when needed
