Closed cooling tower of steam turbine

Release time：

The closed cooling tower of steam turbine is as follows:
Do you know the working principle of closed cooling tower?
Closed cooling tower is a device that uses the contact between water and air to evaporate waste heat formed in industry or refrigeration and air conditioning. Now, the Wuxi closed cooling tower manufacturer Jiahe Cooling Equipment will share with you the working principle of the lower closed cooling tower, the working principle of the closed cooling tower and the role of each stage?
Working process of closed cooling tower:
The cooling materials (softened water, oil or other liquids) are driven by the main circulating water pump and circulated in the middle of the equipment to be frozen in the heat exchanger (such as switching power supply, furnace body, etc.)., Then spray water evenly on the heat exchanger. A uniform water film is formed on the outer surface of the heat exchanger. The cold air enters the tower from the air inlet under the tower body and flows counter current with the spray water through the surface of the heat exchanger. In this process, there are two methods of heat exchange, namely, cold air. The heat conduction between the cooling medium and the sprayed water evaporates and absorbs heat. After heat absorption, saturated moist and hot air is discharged into the atmosphere through the fan, and the remaining spray flows into the water tank at the lower part of the tower. Transfer to painting system. In this way, the cooling medium in the heat exchanger is cooled.
1. Closed cooling tower circulating water system:
The cooling water system of the circulating system of the FRP cooling tower must have a certain residual kinetic energy (20% - 25%). During operation, these energies will be collected on a certain valve, and these energies will be wasted with the passage of time. The external turbine engines use the kinetic energy of overcapacity to convert them into reasonable mechanical equipment power energy, and then replace 100% of the closed cooling tower fan motor to save power engineering.
2. How external turbines achieve motor drive efficiency:
Understand the residual energy in the design of closed cooling tower circulating cooling water system. At the same time, the impeller design of the turbine is also critical. The remaining energy is mainly composed of the following six parts:
1) The margin value that must be considered in the design of circulating water system;
2) Potential energy utilization of heat exchange equipment;
3) Self regulation capability of turbine;
4) Kinetic energy conversion efficiency of circulating water system;
5) When the valve is not opened in place, the energy consumed by the valve.
6) The low flow rate can meet the system requirements through the combined diversion method.
3. Reconstruction of old closed cooling tower
The closed cooling tower and heat exchange equipment are circularly driven by the water pump. The external turbine uses back pressure energy to convert and drive the turbine to drive the fan. Generally, three closed cooling towers are used for energy-saving transformation. The actual usage is about 60%. Considering the change of manufacturing requirements, the way of environmental protection and energy conservation is: two towers for water turbine generator unit drivers and one tower for motor drivers. They keep it in summer.
4. New tower design of closed cooling tower
The external turbine cares about the return water working pressure or return water, so as to consider the role of the centrifugal fan of the booster driver. The law of environmental protection and energy conservation - what is the speed ratio of the centrifugal fan for the return water volume or working pressure transformation. The speed of the external turbine increases or decreases as the system flow increases or decreases. There are 3 external turbine closed cooling towers in the system, and 3 towers of the turbine outlet pipe are connected. The bypass valve is used to regulate the flow and facilitate maintenance.
The above is all about how the closed cooling tower works and the role played by each link. I hope to help everyone have a better understanding of the use of closed cooling towers.
