In some embodiments, a liquid level sensor is also provided in the spray tower 200.
According to the water vapor recycling system provided by the embodiment of the invention, the cooling water in the spray tower 200 can be detected through the liquid level sensor, when the storage amount of the cooling water in the spray tower is lower than a set value through spraying, the liquid level sensor sends a switching signal to the controller (not shown), and the controller controls the external water source (not shown) to inject water into the spray tower 200.
Specifically, according to the water vapor recycling system of the embodiment of the present invention, in the slag flushing process of the slag flushing tank 100, the first sealing cover 6 and the second sealing cover 7 above the slag flushing tank are located at the sealing positions, the cooling water in the spray tower 200 enters the slag flushing tank 100 for slag flushing, during the slag flushing process, a large amount of water vapor generated in the slag flushing tank 100 is sucked into the spray tower 200 through the exhaust pipe 41 connected to the air draft device 4, the condensed water in the spray tower 200 is circulated by the circulation pump 400 to cool the water vapor sucked from the slag flushing tank 100, the condensed water vapor is stored in the spray tower 200, part of the uncondensed water vapor is further condensed into water through the demister 300 and stored in the spray tower 200, and the rest of the water vapor is discharged out of the spray tower 200 through the centrifugal fan 500. During the slag dragging process of the grab bucket 600, the closed cover adjacent to one side of the grab bucket 600 is partially moved away to one side of the slag flushing tank 100 away from the grab bucket 600 through the driving motor (namely, at least one of the first closed cover 6 or the second closed cover 7 is located at an open position), and after the slag dragging process of the grab bucket 600 is finished, the closed covers are reset (namely, the first closed cover 6 and the second closed cover 7 are located at closed positions).
The liquid level in the slag flushing tank 100 is reduced due to the dissipation of a large amount of water vapor; the level of liquid in the spray tower 200 rises due to the condensed water formed by the received water vapor in the spray tower 200. Due to the liquid level difference, the condensed water circulates by gravity and flows back to the slag flushing pool 100 through the overflow pipeline, and water is supplemented to the slag flushing pool 100. When the liquid level in the spray tower 200 is insufficient, the external cooling water source 700 can be used for supplementing water.
