Abstract

The invention relates to a bell-type furnace cooling water waste heat utilization method and system. The bell-type furnace cooling water is conveyed into a non-pressure water return pool; the bell-type furnace cooling water in the non-pressure water return pool is conveyed to the bell-type furnace inner cover through a water return pump and used for cooling the bell-type furnace inner cover; conveying to a bell-type furnace platform for cooling the bell-type furnace platform; and the air is conveyed to the air-conditioning terminal unit for air-conditioning heating. Meanwhile, the inner cover of the bell-type furnace, the non-pressure water return pool and the water return pump form a heating circulation system; the bell-type furnace coil base, the non-pressure water return pool, the water return pump, the circulating water cooling tower, the circulating water collecting pool and the circulating water supply pump form a water supplementing circulating system. The non-pressure water return pool, the water return pump, the air-conditioning water heating water pipe, the air-conditioning terminal unit and the air-conditioning water return pipe form a heating circulating system; according to the invention, the waste heat of the cooling water of the bell-type furnace is recycled, and resources are saved.

Description

technical field [0001] The invention belongs to the technical field of bell-type furnaces, and in particular relates to a method and system for utilizing the waste heat of cooling water of a bell-type furnace. Background technique [0002] At present, due to the high temperature of the water after cooling in the bell-type furnace, the water after cooling in the bell-type furnace is usually transported to the non-pressure return water tank, and then sent to the cooling tower of the circulating water station through the return water pump for cooling, and then flows into the circulating water collection tank by itself. , the water in the circulating sump is pressurized by the circulating water supply pump and sent back to the bell-type furnace for cooling of the bell-type furnace. However, in this way, the heat energy in the cooling water of the bell-type furnace is not utilized, resulting in heat loss. At the same time, the central air conditioner needs to be turned on in wint...
