The anti-freezing device comprises a cooling tower radiator coil tube, and further comprises a cooling water circulating device, an anti-freezing solution circulating device and a purging device, wherein the cooling tower radiator coil tube is connected with the cooling water circulating device through a circulating water pipeline, the cooling tower radiator coil tube is connected with the anti-freezing solution circulating device through an anti-freezing solution pipeline, the purging device is connected with the cooling water circulating device through an anti-freezing solution pipeline, and the purging device is connected with the circulating water pipeline and the anti-freezing solution pipeline through purging pipelines. According to the invention, the anti-freezing requirement of a copper coil pipe in the closed cooling tower in winter can be effectively met.

Description

technical field [0001] The invention relates to an antifreeze device, in particular to an antifreeze device for a closed cooling tower. Background technique [0002] The circulating water cooling tower is divided into open type and closed type according to the heat dissipation structure. It is to dissipate heat from the hot water generated after the cold water passes through the cooling equipment through the internal mechanism of the water tower, so as to achieve the purpose of recycling again. [0003] The cooling tower mentioned this time is a closed cooling tower, and its working principle is mainly: hot water is generated by heat exchange through the equipment heat exchanger and other mechanisms, and enters the closed copper coil in the cooling tower for internal circulation. The secondary side circulating water circulation system draws the circulating water in the tower pool through the water pump and sprays it from the top of the tower down to the copper coil, and then...

Problems solved by technology

Problems with this solution: Take the cooling circulating water used for engine testing as an example, when the antifreeze is added at a ratio of 30%, it is an example to prevent the cold winter at minus 15°C

The circulating water used to cool the equipment pool exceeds 100 tons, and at least 30 tons of antifreeze are used, which results in high operating costs; it affects the humidification accuracy of the engine test intake air conditioner (it needs to circulate bad water to maintain the engine intake humidity); the circulating water uses lossy replenishment There will be dilution, and the proportion of antifreeze is difficult to guarantee; the water containing antifreeze in the maintenance and cleaning pool is directly discharged, causing environmental pollution
