Referring to fig. 1-2, the invention discloses a preheating deicing ice cold accumulation tank, which comprises an ice accumulation tank 1 and a water return tank 2. An ice storage tank inlet 10 is formed in the upper portion of the ice storage tank 1, and the ice storage tank inlet 10 is used for injecting ice water. The bottom of the backwater pool 2 is provided with a backwater pool water inlet pipe 20, the backwater pool water inlet pipe 20 is connected with a water pump 21, and the water pump 21 injects backwater water 52 into the backwater pool 2 through the backwater pool water inlet pipe 20. The side wall of the water return tank 2 is provided with slots 22 with different heights. The water flowing back 52 with relatively high temperature injected from the water inlet pipe 20 of the water returning pond has relatively low density and can be quickly diffused upwards, so that the water flowing back 52 with relatively low temperature in other parts of the water returning pond 2 can be quickly subjected to heat exchange, and the temperature of the water returning 52 in the whole water returning pond 2 can be kept balanced.
The bottom surface of the water return tank 2 is arranged at a height higher than the ice layer 5 in the ice storage tank 1, a water return pipe 3 is connected between the top of the ice storage tank 1 and the water return tank 2, and the water return pipe 3 can be inserted into any slot 22. The water return pipe 3 enables the ice storage tank 1 to be communicated with the water return tank 2, and the water return 52 in the water return tank 2 can be freely injected into the ice storage tank 1. The water inlet height of the water return pipe 3 can be adjusted by the slot 22, when the temperature of the water return pipe 52 is relatively high, the insertion height of the water return pipe 3 can be properly reduced, and excessive water can be pumped out, so that the water quantity in the water return tank 2 is reduced, and after the water quantity is reduced, the heat exchange with the outside is reduced, so that the burden of the system can be reduced.
The end of the return pipe 3 extending into the ice bank 1 is provided with a flow limiting pipe 33, and the flow limiting pipe 33 is arranged in the vertical direction and is positioned at the center of the ice bank 1. The upper portion of the flow restriction pipe 33 is closed, and the lower portion is opened, and the flow direction of the return water 52 flowing through the flow restriction pipe 33 becomes vertically downward.
