Working principle of cooling tower of medium frequency induction furnace
In the production of medium frequency induction furnace, it is necessary to cool down the medium frequency induction furnace. If the price cost is not considered, the cooling method of medium frequency induction furnace is better, and the cooling of closed cooling tower is used to cool down. However, in the technical exchange of IF induction furnace, many customers are not clear about the cooling principle of the cooling tower of the medium frequency induction furnace. Let’s discuss the cooling principle of closed cooling tower together.
The cooling tower of medium frequency induction furnace is actually a heat dissipation device, which makes the medium to be cooled in the tower cooling by the evaporation and heat dissipation of water. In order to make full use of water resources, reduce the load of urban water supply network, and to reduce the operating cost, the cooling water used for medium frequency induction furnace cooling is recycled by cooling tower. The cooling tower of medium frequency induction furnace uses natural ventilation or mechanical ventilation method to cool the hot water sprayed.
In the production of medium frequency induction furnace, cooling tower is widely used. The water in the cooling tower of medium frequency induction furnace is evenly sprayed on the cooler by spray nozzle. The cooling medium is heat exchange with water through the cooler. During this process, the medium is cooled. The water absorption temperature on the cooler surface flows to the packing layer, forming a uniform water film on the packing surface, which increases the contact surface between water and air and the contact time is prolonged, Water and air are fully heat exchanged.
There are two ways of air flow: one is to distribute the air evenly by the air inlet louvers of the cooling tower, and the natural suction force generated by the air duct will suck the air from the bottom to the upper; Another method is to install fans to make air flow, i.e. natural ventilation and mechanical ventilation. After the air is transferred through medium and water, the temperature increases and the water content increases, and it is discharged into the atmosphere when the tower top is near saturation state. At this time, the medium in the cooling tower of medium frequency induction furnace has been cooled. The water temperature drops after the heat transfer between the filler layer and air. The cooled water falls into the bottom water pan, which is recycled by the water pump to the water distribution system and then poured back to the cooler for cooling cycle.
