Anti-freezing apparatus for air cooling tower system of indirect air cooling unit

Abstract

The invention provides an anti-freezing apparatus for an air cooling tower system of an indirect air cooling unit. The anti-freezing apparatus comprises an air cooler, an air cooling tower, a radiator and a draining valve, wherein one end of the air cooler is connected with the air cooling tower, the joint of the end of the air cooler and the air cooling tower is provided with a first valve, the other end of the air cooler is connected with the air cooling tower, the joint of the other end of the air cooler and the air cooling tower is provided with a second valve, the air cooler is connected with a self-circulating pump and a cold water circulating pump, the self-circulating pump and the cold water circulating pump are connected in parallel, the self-circulating pump is arranged between and connected with the air cooler and the second valve, the radiator is connected with the air cooler, the air cooling tower is connected with the draining valve, and the air cooling tower is composed of a fan, a spraying device and a water tank. According to the invention, through arrangement of the self-circulating pump, the cold water circulating pump, a drainage pump and a radiating pump, the air cooler and the air cooling tower are prevented from frost damage according to different indoor and outdoor temperatures and different operation modes, so stable and reliable working is guaranteed all the year round.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to an antifreeze device for an air cooling tower system of an indirect air cooling unit. Background technique [0002] Units 7 and 8 of the fourth phase of Taiyuan Second Thermal Power Plant are 2×200MW air-cooled units. At that time, as the air-cooled units in my country had just started, and during the freezing winter period, the radiator leakage of the fourth-phase air-cooled tower was relatively serious. According to statistics, from 1994 to 1994 In February 2009, 5,174 and 6,101 air-cooling towers of units 7 and 8 leaked respectively, and the number of leaking tubes from the radiator of tower 7 accounted for 11.73% of the total number of tubes, and the number of leaking tubes from the radiator of tower 8 accounted for 16.1% of the total number of tubes , 1,601 severely deformed tubes (not leaking) of the radiator of tower No. 7, and 1,697 severely deformed tubes ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide an antifreeze device for the air-cooling tower system of the indirect air-cooling unit, so as to solve the problem that the radiator of the air-cooling tower in the prior art leaks more seriously and causes a large amount of economic losses
