The invention relates to an energy storage tank, in particular to an energy storage tank with double water distributors, and belongs to the field of power equipment.
Background
At present, an energy storage tank is mostly applied to heat generated by absorbing the power on line through equipment such as an electric boiler when a thermal power plant stores electric power and adjusts the peak, and the heat is used for supplying heat to a heat network. In order to ensure that a thermocline in the energy storage tank is single and stable, when an energy storage tank system is designed to operate, the energy storage tank needs to completely finish hot water injection or discharge when in switching operation, and the energy storage tank is in discontinuous operation due to the fact that electric power peak shaving is executed in different time periods, namely heat storage and heat release of the energy storage tank are in discontinuous operation.
However, when the energy storage tank is applied to a heating project requiring twenty-four hours of continuous operation, namely when heat storage and heat release of the energy storage tank need to be switched rapidly, the original system needs to switch the heat storage and heat release operation by starting and stopping the heat storage pump and the heat release pump; frequent starting and stopping in a heating season will influence the safe and reliable operation of the pump, the service life of the pump set is shortened, and the energy storage tank stops operating during the switching period of starting and stopping of the heat storage pump and the heat release pump.

Principle of operation
The working principle of the invention is explained in conjunction with fig. 2 and 3

When the energy storage tank is in a heat storage state, the #1 valve is opened, the #2 valve is closed, the #3 valve is closed, and the #4 valve is opened. The low-temperature water passes through the valve No. 1 and is pumped out through the pump group, and the high-temperature water enters the energy storage tank through the valve No. 4 after being decompressed.
When the energy storage tank is in a heat release state, the #1 valve is closed, the #2 valve is opened, the #3 valve is opened, and the #4 valve is closed. The low-temperature water enters the energy storage tank through the No. 2 valve after being decompressed, and the high-temperature water is pumped out through the No. 3 valve to supply heat to the outside.
When the working state of the energy storage tank needs to be switched, the pump group does not need to be closed and then the valve action is carried out, and the working state switching of the energy storage tank can be completed by actuating the #1 valve, #2 valve, #3 valve and #5 valve, so that the switching is very convenient and easy to operate.
