Dry and wet separation multi-air-inlet composite closed cooling tower and operation adjusting method thereof

Abstract

The invention discloses a dry and wet separation multi-air-inlet composite closed cooling tower and an operation adjusting method thereof, and belongs to the technical field of circulating water cooling. A tower body is divided into a left chamber and a right chamber by a partition plate disposed within a tower body cavity, the left chamber is provided with an air valve and a finned tube heat exchanger from top to bottom, the right chamber is provided with a water absorbing device, a spraying and discharging pipe, a light pipe heat exchanger, a filler and a water collecting tank from top to bottom, a first fan and a second fan are arranged at the top of the left chamber and the top of the right chamber respectively, and a first air inlet, a second air inlet and a third air inlet are arranged on the left side wall surface of the left chamber, the bottom of the left chamber and the right side wall surface of the right chamber. According to the tower, dry air cooling and evaporative cooling are separated, flexible switching and combination of dry air cooling and evaporative cooling under various air inlet working conditions can be achieved by controlling opening states of the different air inlets and the different fans according to changes of an outdoor environment temperature and a cooling heat dissipation load so as to achieve the maximum energy-saving and water-saving effect.

Description

technical field [0001] The invention belongs to the technical field of circulating water cooling, and relates to a closed cooling tower and an operation adjustment method, in particular to a method which separates dry air cooling and evaporative cooling, and can flexibly adjust the air intake state and dry air cooling. A dry-wet separation multi-inlet composite closed cooling tower combined with cooling and evaporative cooling and an operation adjustment method thereof. Background technique [0002] Closed cooling tower, as a kind of circulating water cooling and heat dissipation equipment, has been widely promoted in all walks of life because of its advantages of energy saving, water saving, and water quality is not easy to be polluted. Existing closed cooling towers generally spray water vertically downward from the upper part of the tower body, and the outdoor natural air is swept upwards vertically (counter-flow tower) or horizontally (cross-flow tower) under the action ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the air intake state of the current closed cooling tower is greatly affected by the outdoor environment, the heat dissipation capacity and cooling heat exchange efficiency of the cooling tower are low, and the dry air cooling and evaporative cooling coils are in the same area, which cannot be based on Due to deficiencies such as flexible adjustment of cooling and heat dissipation loads and operating conditions, a dry-wet separation multi-inlet composite closed cooling tower and its operation adjustment method are proposed. Using tunnel wind as the air intake of the cooling tower can reduce the intake air temperature and improve cooling. Efficiency, can be combined with other natural air intake to achieve flexible conversion and adjustment between different cooling modes, separate dry air cooling and evaporative cooling settings, and can turn on the number of fans and adjust the speed of fans and water pumps according to changes in the outdoor environment, thereby Change the air volume and spray water volume in real time to achieve maximum energy saving and water saving
