Abstract

The invention discloses an anti-freezing device of a closed cooling tower. 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...
