Mechanical cooling tower white smoke removing device

Abstract

The invention discloses a mechanical cooling tower white smoke removing device comprising a tower body. An exhaust port is arranged at the upper end of the tower body, a fan is arranged in the exhaustport, a defogger, a water distributing system, a heat exchange filler and an air intake grille are sequentially arranged on the portion, below the fan, in the tower body, the lower portion, below theair intake grille, at the bottom of the tower body is used as a circulating water tank, a plurality of water flow passages and a plurality of air flow passages adjacent to the plurality of water flowpassages are distributed inside the heat exchange filler alternately, the water distributing system includes a water distributing main pipe and a plurality of water distributing branch pipes, the water distributing main pipe is located at the position, above a packing layer and below the defogger, inside the tower body, and the water distributing main pipe communicates with and is connected witha minor water distributing machine arranged inside each water flow passage through the corresponding water distributing branch pipe. The mechanical cooling tower white smoke removing device has the advantages that heat of high-temperature circulating water is transferred and the circulating water is cooled by adopting an air-liquid indirect heat exchange mode, and only the air-liquid temperature changes during the heat exchange process, so that the water vapor evaporation amount of the high-temperature circulating water is greatly reduced during the heat exchange process, high temperature andlow humidity unsaturation emission of the air subjected to heat exchange is realized, the white smoke phenomenon of a mechanical cooling tower in winter is eliminated, and water resources are saved.

Description

technical field [0001] The invention relates to the field of resources and environmental protection, in particular to a white smoke elimination device for a mechanical cooling tower. Background technique [0002] The cooling tower is a device that uses ambient air as a circulating cold source to absorb and discharge heat from high-temperature circulating water into the atmosphere to reduce the temperature of circulating water; its cooling is to use high-temperature circulating water and air in countercurrent contact to exchange heat and cold to generate steam, steam The heat is taken away by volatilization to achieve the purpose of evaporative heat transfer, convective heat transfer and radiation heat transfer, etc., to dissipate the waste heat generated in industry or in refrigeration and air conditioning to reduce the water temperature, so as to ensure the normal operation of the system. With the continuous development of the cooling tower industry, in order to improve the...
