Embodiment 1

[0039] According to one or more embodiments of the present invention, with reference to Figure 1~Figure 3 As shown, the specific working process of the fog-eliminating cooling tower of the present invention is as follows (spring, autumn and winter), wherein the rotating baffle 145 is in the closed (horizontal) position, and the louvers 16 are opened.

[0040] The circulating hot water is evenly sprayed on the water-sprinkling filler 12 through the first sprayer 13, and the external dry and cold air, driven by the fan 21, enters from the air inlet (not shown in the figure) at the lower part of the tower body 1 and is sprayed. The water fill 12 flows upwards. The dry and cold air from the outside contacts with the circulating hot water sprayed by the first shower 13 above the water-spraying packing 12 in countercurrent, and transfers mass and heat on the surface of the water-spraying packing 12, and the circulating hot water is cooled and enters the bottom of the water-spraying...

Embodiment 2

[0044] In general, the anti-fog cooling tower needs to turn on the anti-fog function in spring, autumn and winter, and does not need anti-fog in summer. According to one or more embodiments of the present invention, with reference to Figure 2~Figure 4 Shown, the specific work process of the mist elimination cooling tower of the present invention in summer is as follows. Wherein the rotary shutter 145 is in the open position and the shutter 16 is closed.

[0045] The circulating hot water is evenly sprayed on the water-sprinkling filler 12 through the first sprayer 13, and the external dry and cold air, driven by the fan 21, enters from the air inlet (not shown in the figure) at the lower part of the tower body 1 and is sprayed. The water fill 12 flows upwards. The dry and cold air from the outside contacts with the circulating hot water sprayed by the first shower 13 above the water-spraying packing 12 in countercurrent, and transfers mass and heat on the surface of the wat...

Abstract

The invention discloses a fog dissipation filler. The fog dissipation filler is formed by arranging a plurality of heat exchange sheets, and a first channel and a second channel which are arranged atintervals and are in not communication with each other are formed among the multiple heat exchange sheets; each heat exchange sheet comprises a plurality of baffling surfaces, a flow guide groove anda liquid collecting groove; the flow guide grooves extend outwards from the junction of two vertically adjacent baffling surfaces, flow guide surfaces are formed at the lower parts of the flow guide grooves, and the flow guide surfaces are downwards deflected relative to the baffling surfaces below the flow guide surfaces; and the liquid collecting grooves are defined by the upper portions of theflow guide grooves and the baffling surfaces above the flow guide grooves, and a semi-closed flow guiding space is formed by the liquid collecting grooves and the flow guide grooves above the liquid collecting grooves. The invention further discloses a fog dissipation cooling tower. According to the fog dissipation cooling tower and the fog dissipation filler thereof, water mist in wet and hot aircan be captured more effectively through cooperation of the flow guide grooves, the flow guide surfaces and the liquid collecting grooves, and the demisting water-saving effect is improved.

Description

technical field [0001] The invention relates to the technical field of cooling towers, in particular to an anti-mist cooling tower and an anti-mist filler. Background technique [0002] In petroleum, chemical and other industries, circulating water cooling systems are widely built. Most circulating water cooling systems use open cooling towers as the main cooling equipment. The traditional open cooling tower uses filler to cool the circulating water. The circulating hot water from the process unit enters the cooling tower spray system and enters the filler from top to bottom. The filler is generally made of PVC sheet, and the water enters the filler to form water along the PVC sheet. The external dry and cold air enters the filler from bottom to top and exchanges heat with the water film. The water film evaporates and cools down. The air is heated and humidified to form hot and humid air. A fan is installed on the top of the cooling tower to discharge the hot and humid air ...
