The specific implementation method is as follows:

[0031] As Figures 1 to 4 shown, a large water beam circulating water cooling device includes a cooling pipeline 2 and a circulating water cooling component. The cooling pipeline 2 is inserted into the inside of the large water beam 1.

By arranging a circulating water cooling component on the large water beam 1, the cooling water in the circulating water tank 7 can be pumped by the circulating water pump 13 into the cooling pipeline 2 inside the large water beam 1 for rapid water cooling. After fully absorbing heat, the cooling water can flow back into the steam drum 9 through the return water pump 16 for the separation of water and steam. Then, the steam can be discharged, and the water returns to the circulating water tank 7 for circulation, greatly improving the cooling efficiency of the large water beam 1 and avoiding the problem of low cooling efficiency of natural circulation. The steam drum is a cylindrical pressure vessel in a water tube boiler used for steam-water separation and steam purification, forming a water circulation loop and storing boiler water.

[0041] Working principle: By setting a circulating water cooling component on the large water beam, the circulating water pump can extract the cooling water in the circulating water tank into the cooling pipeline inside the large water beam for rapid water cooling. After fully absorbing heat, the cooling water can flow back into the steam drum through the return water pump for water-steam separation. Then, the steam can be discharged, and the water returns to the circulating water tank for circulation, greatly improving the cooling efficiency of the large water beam and avoiding the problem of low cooling efficiency of natural circulation. By setting a return water flow meter on the return water pipeline and a circulating flow meter between the steam drum and the circulating water tank, the circulating water volume during the circulating cooling process can be monitored, facilitating the replenishment of cooling water and bringing convenience to the management of staff. By setting a reinforcing sleeve outside the cooling pipeline and the return water pipeline, the pipeline strength can be improved, enhancing the compressive resistance and anti-breakage ability. By setting a high-temperature resistant inner pipe inside the cooling pipeline and the return water pipeline, the high-temperature resistance performance of the pipeline can be further improved, enhancing the service life.
