Yunuo Cooling Technology will introduce the closed cooling tower manufacturer to tell you what maintenance the closed cooling tower needs to do in winter.
During the actual combination process of the closed cooling tower, it will have some structures of its own. From the perspective of the framework, basically some of their amplitudes are defined at 0.14 mm. If viewed from the wind tunnel, the entire closed cooling tower will be The relevant processing is carried out through the material of FRP. This kinetic energy can better recover some wind or air pipes, and can also make full use of some theories of airflow harmony, and can be combined with the time or measurement data of this project. Some practical situations are used to adopt the elliptic curve in all aspects. In this case, whether it is a curve or some other straight line of natural wind profile, it can relatively better eliminate some phenomena flowing in the air. In this way, some vortex areas will be avoided, and there will be more negative pressure areas in the airway core, and even they will greatly reduce the original use area in the entire negative pressure area, and the wind speed of the outlet section will be significantly more uniform. Some.
For closed cooling tower manufacturers, when the circulating cooling system is used in the northern cold region, after a freezing accident occurs, it can cause production interruption, long repair and recovery time, and directly cause greater economic losses to users. Therefore, system antifreeze is an important If the closed cooling tower does not need to be operated in winter, the spray water and internal circulating water must be drained when it is shut down. The internal circulating water is recommended to be forced to be evacuated by compressed air, and the carbon steel tube heat exchanger is not recommended to be evacuated to prevent freezing.
The problem of anti-freezing of closed-circuit cooling towers in the case of year-round operation. If the closed-type cooling towers that operate all the year round are equipped with an electronic control system, the number of cooling towers may change due to the load change of the main system, so it is also necessary to consider anti-freezing. question. Unused equipment can be evacuated before winter to prevent freezing.
The antifreeze problem of the closed cooling tower is that the closed cooling tower has two parts: the spray water system and the internal circulating water system (softened water). The antifreeze problem of the spray water system is usually to add an electric heater in the water pool, which is generally turned on when the spray water is lower than 5°C, and stopped when the water is above 8°C. The temperature probe transmits the signal to the control cabinet to automatically control the start and stop of the electric heater. The power selection of the electric heater is determined according to the circulating water volume and the outside air temperature.
For the antifreeze of the internal circulating water system, ethylene glycol solution can be added or electric heating equipment can be added. The freezing point temperature of the ethylene glycol solution is required to be selected below the local ultra-low temperature. For larger cooling systems, it is possible to consider digging a pool to pour the spray water into it, which can save electricity costs due to electric heating operation, and can also put medicines in the pool to improve the quality of the spray water.
The above is the relevant content introduced by Uno Cooling Technology.
