Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a drop-type self-generating cooling device for a cooling tower. Background Art

[0002] Sludge treatment refers to the process of subjecting the sludge generated during sewage treatment to a series of treatments to reduce its volume, stabilize its properties, render it harmless, and maximize its resource utilization. The main steps in sludge treatment include concentration, conditioning, dehydration, stabilization, drying, or incineration. These treatment steps help reduce the impact of sludge on the environment and create conditions for its eventual disposal or resource recovery. The hot water generated by sludge treatment must be cooled in a cooling tower to facilitate subsequent water circulation. The height of the cooling tower is determined based on the heat exchange capacity. Its working principle is to use convection between the incoming wind and the water pouring down from above to remove the heat source. A portion of the water evaporates in the convection, carrying away the corresponding latent heat of evaporation, thereby lowering the water temperature.

[0003] At present, the hot water outlet of sludge treatment plants is located at a high place after sludge treatment. The hot water is then directly transported to the cooling tower through pipes for cooling. During the cooling process, the water flow is not fully utilized and thus flows away in vain, which causes a large amount of energy waste. At the same time, in order to increase the exhaust efficiency, some cooling towers will also add an electrically driven fan inside the cooling tower, which leads to a further increase in the operating energy consumption of the cooling tower and an increase in costs.

[0025] The diameters of the Chuanliu bin drainage pipe 13, the Chuanliu bin water inlet pipe 15 and the drop connection pipe 16 are 75~80mm, and the water volume is required to be full.

[0026] The height between the water source 20 and the flow chamber 14 is 5~15m.
