Composite cooling tower

Abstract

The invention relates to the technical field of cooling, in particular to a composite cooling tower which comprises a spraying system, a water collecting tray, a fan and a vertical falling film heat exchanger, and the vertical falling film heat exchanger is vertically arranged below the spraying system. A heat exchange filler is arranged in the water collecting tray, and the heat exchange filler is arranged below the vertical falling film heat exchanger. A conveying water pipe is connected with a first pipeline, an inlet header is connected with the conveying water pipe through a first pipeline, and a first stop valve is arranged between the conveying water pipe and the inlet header; and an outlet header is connected with the water collecting tray through a second pipeline and a third pipeline, and a second stop valve and a third stop valve are correspondingly arranged on the second pipeline and the third pipeline respectively. According to the composite cooling tower, the functions of a closed cooling tower and an open cooling tower can be integrated under the condition that the size and the weight are basically unchanged, and the problems that in the prior art, cooling heat exchange equipment is single in function and low in cooling efficiency are solved.

Description

technical field [0001] The invention relates to the technical field of cooling, in particular to a composite cooling tower. Background technique [0002] The cooling tower is a kind of high-efficiency cooling equipment, including closed cooling tower and open cooling tower. It mainly uses the latent heat of evaporation of water to remove the heat of the process fluid to complete the cooling of the process fluid. The process fluid is usually circulating water; at the same time The recycling of spray water is realized. [0003] For closed cooling towers, the process fluid flows in the coil and conducts heat to the outside of the tube through the tube wall; at the same time, there is spray water outside the tube for spraying, forming a water film on the outer wall of the tube, under the action of air , Through spray evaporation, heat transfer and mass transfer heat exchange process occurs outside the tube, so as to realize heat transfer. [0004] The closed cooling tower can ...

AI Technical Summary

Problems solved by technology

[0009] 1. The cooling towers in the prior art have relatively single functions, and can only have one of the functions of closed cooling towers or open cooling towers, and are not suitable for use in areas with particularly large climate changes throughout the year

[0010] 2. Existing cooling towers use horizontal coils. When the spray water flow rate is large, the coils are easy to vibrate, and the collision noise is relatively large. Since the coils are mostly arranged in a triangular fork row, the air flows to a relatively large area. Small, large resistance, and easy scaling on the windward side, affecting the heat transfer effect
