Requirements for inlet water temperature of closed cooling tower

Requirements for inlet water temperature, lost cooling water volume and temperature adjustment method of closed cooling tower
The water loss of the closed cooling tower is the key parameter for water saving operation. The amount of water loss in the cooling water depends on the amount of water loss in the cooling water. The water loss of the cooling tower includes volatilization loss, wind blowing loss and sewage treatment loss. Volatilization loss is unavoidable; The wind blowing loss means that there are water droplets in the cyclone discharged from the closed cooling tower that are slightly blown out of the tower by the wind; In addition, the waste water treatment loss of the closed cooling tower is to prevent the water from being carried away by the cooling reservoir due to the solid solubility from generating scale.
You should know that the cooling water volume of closed cooling tower can be adjusted, which is mainly reflected in the fact that the cooling tower with given model and specification has the characteristics that the difference between inlet and outlet water temperature will not change when the pressure changes during operation. Therefore, the cooling water volume of the tower can be increased by increasing the power supply working pressure, and the water volume of the tower can be adjusted by changing the nozzle diameter.
In addition, the closed cooling tower is also a kind of conditioning treatment system. It absorbs the equipment temperature of industrial production according to the digestion of industrial production cooling water, and dissipates the heat into the gas after touching the gas, so as to reduce the cooling water temperature. According to the hot and cold double flow hydrodynamics, the cooling block touches the cooling water based on the temperature difference and volatilizes the water into the air to achieve its own cooling effect.
When the closed cooling tower is in operation, each pipeline step shall be kept smooth without blocking. If blocking occurs, it shall be removed immediately to keep the cooling tower flowing smoothly, which can have cooling effect, and can increase the service life of machinery and equipment.
How to Solve the Problem of Excessively High Outlet Water Temperature of Closed Cooling Tower
When finalizing the design scheme of the closed cooling tower, the design standards are carried out for the inlet and outlet temperature, water volume in the circulating system, cooling capacity and other index values. Under the standard of standardized working conditions, each task index value of the cooling tower shall meet or exceed the design specification. If the outlet temperature of the cooling tower is too high, it must be diagnosed systematically and adjusted immediately. Next, the network editor will give you a detailed introduction to the expertise in these areas - how to solve the problem of high water outlet temperature of closed cooling tower
1、 Excessive water volume of circulating system
The excessive water volume in the circulating system will be caused by the expansion of the server load, as well as improper adjustment of the gate valve. Too much water in the circulating system will reduce the heating characteristics of the cooling tower system software, reduce the temperature of the cooling tower, and reduce the cooling performance.
The problem of excessive water flow in the circulating system caused by excessive server load should be handled according to the relativity between the replacement and the required tonnage, cooling capacity and other performance indicators. If the water volume of the circulating system is too high due to improper adjustment of the gate valve, adjust the gate valve to the appropriate water volume immediately.
2、 Part of the outlet of the water distribution pipe is blocked
A part of the outlet of the tap water pipe in the closed cooling tower is blocked, causing bias flow. Blocking and bias flow will harm the water outlet rate and water distribution quality, reduce the actual effect of water steam heat exchanger, and cause excessive outlet temperature.
By eliminating the blockage in the water distribution pipe (equipped with a stainless steel sink), the hydrodynamics in the water distribution pipe can be smooth, and the water distribution speed and actual effect can be restored.
3、 Gas inlet and outlet blocked or short circuited
The gas in and out of the closed cooling tower is blocked or short circuited, causing abnormal air inlet and outlet conditions, which may endanger the actual aerodynamic effect of the tower body and the energy discharge, resulting in excessive outlet temperature. If there is a problem of poor gas inlet and outlet, quickly find out the cause and repair the smooth gas inlet and outlet flow path.
