A device for increasing the heat storage temperature of a water tank

Abstract

The invention discloses a water tank heat storage temperature increasing device. The water tank heat storage temperature increasing device comprises a heat source, a heat storage water tank and a heatuser. The heat source communicate with the heat storage water tank through a heat storage pipeline. The heat source communicates with the heat user through a heat supply pipeline. The heat storage water tank communicates with the heat user through a heat storage heat supply pipeline. The upper end of the heat storage water tank is provided with a connecting pipeline. An open container is arrangedon the connecting pipeline. The open container communicates with the heat storage water tank through the connecting pipeline. The saturated pressure intensity and saturated temperature of water in the heat storage water tank are increased through the open container. According to the water tank heat storage temperature increasing device, the height of the liquid level of the water in the heat storage water tank is increased through the open container and the connecting pipeline, so that the pressure intensity of the water in the heat storage water tank is improved, and then the temperature ofthe water in the heat storage water tank is increased. On the one hand, the heat storage capacity of the heat storage water tank is improved in the heat storage process; and on the other hand, the water yielding temperature of the heat storage water tank can be increased in the heat supply process. Accordingly, the supply water temperature of a whole heating supply system is high.

Description

technical field [0001] The invention belongs to the technical field of heat supply and storage, and in particular relates to a device for increasing the heat storage temperature of a water tank. Background technique [0002] With the continuous development of heating technology, more and more attention has been paid to how to improve the overall efficiency of the heating system, and the role of the heat storage tank cannot be ignored.

Problems solved by technology

However, since the water surface is in direct contact with the oxygen in the air, the water tank and piping are easily corroded.

[0004] Moreover, the water surface of the heat storage tank is located inside the heat storage tank, so the saturation pressure of the water in the heat storage tank is low, resulting in a low saturation temperature of the water inside the heat storage tank. Therefore, in the heating system, the water storage The outlet water temperature of the hot water tank is low when heating, and the heat stored in the hot water tank is low when the heat is stored. Therefore, the open hot water tank seriously affects the economic benefits of the system operation.
