Overview of Closed Cooling Towers

Uno Cooling Technology will give you an overview of closed cooling towers.

The complete set of closed cooling tower equipment consists of main engine, water tank, circulating water pump and electric control cabinet. The main engine is composed of shell, heat exchanger, fan, spray pump, water collector, water tank and pipeline valve and other components. During the working process of the closed cooling tower, the cooling medium (soft water, oil or other liquid) is driven by the main circulating pump to circulate between the heat exchanger and the equipment to be cooled, and the spray water is evenly sprayed on the heat exchanger. A uniform water film is formed on the outer surface of the heater, and the cold air enters the tower from the air inlet below the tower body, and flows through the surface of the heat exchanger countercurrent to the spray water.

There are two modes of operation for closed cooling towers. Air cooling, air cooling + spray. The switching of the two modes is automatically carried out by the electronic control system according to the requirements of the working conditions to achieve energy saving and consumption reduction. The main principle of the closed cooling tower is that the spray water evaporates on the outer wall of the coil to cool the cooling water flowing in the tube, and at the same time, the generated water vapor is taken away in time by the fan. A small part of the spray water evaporates, and the rest is collected by the chassis and recirculated. The higher temperature cooling water from the condenser is pressurized by the cooling water pump and sent to the cooling coil of the closed cooling tower.

On the other hand, the water in the cooling tower chassis is pumped into the spray coil by the pipeline pump, and sprayed on the outer surface of the cooling coil to vaporize and absorb the heat of the cooling water in the coil, so that the temperature of the cooling water can be reduced. At the same time, by the suction effect of the fan installed on the water baffle, the air flows through the cooling coil from bottom to top, and exchanges sensible heat and latent heat with the spray water, which not only strengthens the cooling coil The surface heat is released, and the water vapor formed by evaporation can also be taken away in time to accelerate the evaporation of water and improve the cooling effect.

Induction heating and metal smelting equipment for closed cooling towers, such as: high and medium frequency quenching equipment, medium frequency power supply and cooling of electric furnaces, induction diathermy furnaces, holding furnaces, etc. Cooling of circulating water for various reactors and condensers in the chemical industry. Cooling of large motors, diesel engines, rectifier equipment, electric welding equipment, hydraulic stations and continuous casting equipment, etc. Metal die-casting molds, injection molds and other large mold cooling. Cooling of industrial solutions, such as quenching liquid, electroplating liquid, etc.

The cooling medium of the closed cooling tower is fully closed and circulated, which can prevent the sundries from entering the cooling pipeline system and the evaporation loss of the cooling medium. Use soft water as cooling medium, no scaling, no clogging of pipelines, and less failures. It adopts the dual cooling method of air cooling and spray water evaporation and heat absorption, and the cooling efficiency is high. The device is small in size, takes up little space, is convenient to move and place, and does not need to build a pool. Using automatic intelligent control, the cooling mode can be automatically changed according to the requirements of the working conditions, and the operation is simple and reliable. Wide range of uses, can directly cool quenching fluid, oil, alcohol and other media that have no corrosive effect on the heat exchanger, the medium has no loss, and the composition is stable.
