The closed cooling tower adopts a closed circulation system to process the liquid with residual heat energy engineering, achieving the actual refrigeration effect of the liquid and flowing gas in the closed circulation system. Compared with open cooling towers, cooling towers have the characteristics of good thermal performance, high processing quality, and high refrigeration efficiency.
In a closed cooling tower, there are many components, and the heat exchanger electromagnetic coil is one of them. There are four common types of aluminum profiles: red copper, stainless steel plate, titanium metal, and aluminum alloy profiles, which have different characteristics. However, regardless of which type of electromagnetic coil is used, strict quality management must be carried out. Each electromagnetic coil is installed in the electromagnetic coil group after strict testing; The assembled electromagnetic coil must be inspected to ensure there are no leaks.
At present, closed cooling towers use electromagnetic induction heating method. The softened water caused by induction heating equipment is immediately introduced into the cooling tower and flows with the copper pipes of the air conditioner, so that the heat is digested and absorbed. The top fan comes out of the tower to lower the temperature required for cooling the circulating water.
For enclosed cooling towers, choosing this water circulation system has significant advantages, namely that the softened water enclosed circulation system does not come into contact with gas, prevents stains and blockages, ensures high refrigeration efficiency, and extends the service life of mechanical equipment,
In addition to induction heating equipment, a dedicated axial flow fan should be installed vertically in a closed cooling tower to achieve the specified exhaust volume and air pressure of the cooling tower. Centrifugal fans are usually installed at the top of the cooling tower, and their rolling bearings are fixed inside the cooling tower; The structure, centrifugal fan, and rolling bearings should be connected with hot-dip galvanized screws and equipped with vibration reduction, which has a good effect.
All water circulation systems of closed cooling towers include water filters, spray circulation pumps, spray water supply pipelines and nozzles, embedded centrifugal pumps, etc. The drainage network adopts a circular layout, forming a ring network with the drainage person in charge above the refrigeration electromagnetic coil, so that the pressure of the sprinkler system is symmetrical.
The water storage tank is located at the bottom of the shell under the enclosed cooling tower. The main structure of the stainless steel sink is tightly integrated with the shell structure, and the stainless steel sink and shell cannot be fixed with hot-dip galvanized anchor bolts. This type of water storage tank is made of aluminum plated and galvanized sheet, with a reasonable volume of not less than 4%, which meets the refrigeration requirements.
