Circulating water emptying and collecting device of closed cooling tower

Abstract

The embodiment of the invention provides a circulating water emptying and collecting device of a closed cooling tower, and relates to the field of closed cooling towers. The circulating water emptying and collecting device of the closed cooling tower comprises a cooling tower box body assembly and a cold area pipe assembly. A fan injects air into a layered S-shaped cold area pipe and a first U-shaped communicating pipe, circulating water in the layered S-shaped cold area pipe and the first U-shaped communicating pipe is discharged through a first water discharging pipe under the action of gravity and air pressure till the layered S-shaped cold area pipe and the first U-shaped communicating pipe have no circulating water and are filled with air, the situations that due to condensation of the circulating water, the layered S-shaped cold area pipe and first U-shaped communicating pipe are blocked, and normal use of the closed cooling tower is affected are reduced, when most filtering holes in the outer wall of a filtering piece are blocked by pollutants, a sweeping piece is opened, the pollutants on the outer wall of the filtering piece are swept off through the sweeping piece, air inlet is smooth, and meanwhile, manual cleaning is reduced.

Description

technical field [0001] The present application relates to the technical field of closed cooling towers, in particular, to a collection device for emptying circulating water of closed cooling towers. Background technique [0002] The closed cooling tower in the related art is composed of a box body and a closed cooling pipe arranged inside the box body. The heat exchange is carried out through the circulating water in the cooling pipe, and the heat dissipation of the circulating water is carried out by the fan on the box body, thereby realizing The purpose of cooling and cooling, but in severe cold areas or seasons, after the closed cooling tower is closed, the circulating water in the closed cooling pipe is easy to condense, which will cause pipeline blockage and affect the use, and the closed cooling tower box In order to reduce foreign matter at the tuyere, a filter is installed. After a long time of use, foreign matter will easily block the filter and affect the air intak...
