Problems solved by technology
When the outdoor temperature is lower than a certain level, and after a period of time, the water in the outdoor part of the cooling water tower inlet pipe will freeze into ice, causing the circulating cooling water system to fail to work normally.

The invention belongs to the technical field of industrial circulating cooling water, and in particular relates to a circulating cooling water system. Set up a bypass pipeline and a solenoid valve in the system, one end of the bypass pipeline is connected to the indoor part of the water inlet pipe of the cooling tower, the other end of the bypass pipeline leads to the hot water pool, and a solenoid valve is installed on the bypass pipeline, and the solenoid valve The power switch is connected in parallel with the power switch of the hot water pump. When the hot water pump is powered on, the solenoid valve is turned off at the same time; when the hot water pump is powered off, the solenoid valve is turned on at the same time; , the cooling water in the water inlet pipe of the cooling water tower all flows to the cooling water tower; when the hot water pump stops, the solenoid valve opens, and the cooling water in the outdoor part of the water inlet pipe of the cooling water tower flows back to the hot water pool through the bypass pipe. The invention effectively prevents freezing in the water inlet pipe of the cooling water tower.
Description
A circulating cooling water system technical field The invention belongs to the technical field of industrial circulating cooling water, and in particular relates to a circulating cooling water system. Background technique At present, the circulating cooling water system commonly used in factories generally consists of cold water pools, cold water pumps, hot water pools, hot water pumps and cooling water towers. The cooling water is pumped out from the cold water pool by the cooling pump, delivered to various cooling water equipment through the cooling water inlet pipe, and then flows back to the hot water pool through the cooling water return pipe after passing through the equipment. The hot water pump pumps out the hot water in the hot water pool and sends it to the cooling water tower through the water tower inlet pipe, where it is sprayed and cooled in the cooling water tower, and then flows back to the cold water pool through the water tower return pipe. In order to ...
