Improved closed cooling tower

Abstract

The invention discloses an improved closed cooling tower, which comprises a tower body. The improved closed cooling tower is characterized in that a fan is arranged at the top of the tower body; the fan is connected with a deceleration device; a water retainer is arranged at the lower end of the fan; a water distribution pipe is arranged at the lower end of the water retainer; the water distribution pipe is connected with a water inlet pipe; a plurality of water spraying taps are arranged at the lower end of the water distribution pipe; a packing layer is arranged at the lower ends of the water spraying taps; a plurality of blowing fans are arranged on an inner wall between the water spraying taps and the packing layer; a plurality of air inlets are arranged on the inner wall of the tower body at the lower end of the packing layer; a water collecting groove is arranged at the bottom of the tower body; the water collecting groove is connected with a water outlet pipe; and a filter screen is arranged between the water collecting groove and the air inlets. The improved closed cooling tower has the advantages that the blowing fans are added; circulating water can be cooled in time and quickly; the cooling speed is improved; the filter screen can filter out impurities in the circulating water; and convenience and quickness are brought to production and operation.

Description

technical field [0001] The invention relates to a cooling tower, in particular to an improved closed cooling tower. Background technique [0002] The function of the cooling tower is to exchange heat between the circulating water carrying the temperature and the material in the tower, so as to achieve the purpose of cooling the circulating water. Generally, the packing layer is used in the cooling tower to cool down. Due to the limited performance of the packing layer itself, it There is a certain upper limit of temperature tolerance, so the packing layer in the tower needs to be replaced frequently, which increases the operating cost. Since the circulating water in the tower is continuously cooling cycle, the temperature is relatively high, and the air and packing layer alone cannot be reached in time. The purpose of cooling, and the circulating water is easy to be contaminated with impurities after passing through the packing layer, which brings difficulties to production....
