A cooling tower device and control method with functions of replenishing water and anti-scaling

Abstract

The invention provides a cooling tower device with water replenishment and anti-scaling functions. The cooling tower device includes a cooling water system, a rainwater collection and purification system, a control device, a water cooling unit, a temperature sensor and a fire water tank system; the cooling water system and The water-cooling unit is connected to the water-cooled unit for heat exchange; the rainwater collection and purification system is connected to the fire-fighting water tank system for supplying water to the fire-fighting water tank system; the fire-fighting water system is connected to the cooling water system for cooling water The system cools down; the temperature sensor is used to detect the temperature of the cooling water exchanging heat from the water cooling unit, and send a signal to the control device, which controls the operation of the entire system. The invention has the advantages that the scaling problem of the cooling tower can be alleviated, the heat exchange efficiency can be improved, and the operating cost can be reduced;

Description

technical field [0001] The invention relates to the technical field of cooling water, in particular to a cooling tower device and a control method with functions of water replenishment and scale prevention. Background technique [0002] With the continuous development of the economy and society, people have higher and higher requirements for the comfort of indoor space, which makes the central air conditioner that cooperates with the water-cooled unit and the cooling tower more and more popular. Therefore, the cooling tower has also been used on a large scale. At the same time, the fire water tank is an essential device for fire fighting. In the process of using the existing cooling tower and fire water tank, there are the following problems: [0003] (1) The packing structure of the cooling tower is easy to scale. Studies have shown that the cooling water will heat up after heat exchange in the water-cooled unit, and the higher the temperature of the cooling water enterin...

AI Technical Summary

Problems solved by technology

Therefore, when the temperature of the water entering the cooling tower in the cooling water system is too high, it is not only easy to scale, but also reduces the heat exchange efficiency of the cooling tower, which in turn affects the operation effect of the entire air conditioning system, resulting in a large loss of operating costs

[0004] (2) The fire water tank will be used except when there is a fire, and the rest of the time does not work, so the fire water is generally static and non-flowing, which makes it easy to generate scale on the wall and bottom of the fire water tank, which leads to inconvenient cleaning and blockage in the later stage pipeline

[0005] (3) When the cooling tower is working, a large amount of water will be taken away by the heat exchange process between the air and the cooling water, which makes the cooling water system often need to replenish water, and the existing method is usually to replenish water through a large amount of tap water, resulting in waste of water

For example, the application date is: 2016.3.21, and the application number is: 201620219012.8. The Chinese utility model patent discloses a cooling tower filler descaling device, which can realize the self-cleaning of the cooling tower and avoid the ash accumulation caused by the cooling tower filler. The efficiency of the heat exchanger decreases, but the problem of replenishing water is not taken into account; another example, the Chinese utility model patent with the application date: 2013.12.03 and the application number: 201320788410.8 discloses a cold storage system for fire water tanks used in chilled water systems. Although the cold storage capacity of the fire water tank is utilized, the scaling problem of the fire water tank is not considered

[0007] Although the above-mentioned technologies can improve certain aspects of the problem, they have not fundamentally and comprehensively solved the above problems
