What are the working principles, characteristics and precautions of the closed cooling tower

  We all know that a closed cooling tower is a combination of a cooler and a wet cooling tower, and it is an evaporative cooling tower. It is suitable for various cooling systems that require high circulating water quality, and is widely used in power, chemical, steel, food and many industrial sectors. Next, what China trlon air conditioner first introduces is what is the operating principle of the closed cooling tower? What are the characteristics? What are the precautions when using? Let's take a look!nU9Cooling tower noise reduction treatment manufacturer

  The principle of closed cooling tower:

  The closed cooling tower uses the principle of absorbing heat when water evaporates to cool the cooled liquid. The spray water (cooling water) is stored at the bottom of the cooling tower, and the working fluid (softened water or other liquid) is closed and circulated in the radiating coil of the closed cooling tower. The spray water is pumped by the spray system through the water distribution system and the spray The nozzle is showered on the surface of the coil, a part of the water is evaporated, and the heat is absorbed, thereby lowering the temperature of the working fluid in the pipe. The water in the hot air and the untranspired water are intercepted by the baffle and flow through the PVC heat exchange layer, and the PVC heat exchange The water in the layer is cooled by the air flowing through, the temperature drops, falls into the bottom water pan, is recirculated to the water distribution system by the water pump, and then poured back onto the coil, thus performing cyclic cooling.nU9Cooling tower noise reduction treatment manufacturer

  Features of closed cooling tower:

  1. Improve production power, soften water circulation, no scaling, no blockage, and no loss;nU9Cooling tower noise reduction treatment manufacturer

  2. Extend the life of the equipment, ensure the reliable and stable operation of the equipment, reduce failures, and eliminate accidents;nU9Cooling tower noise reduction treatment manufacturer

  3. Fully closed circulation, no impurities entering, no medium transpiration, no pollution;nU9Cooling tower noise reduction treatment manufacturer

  4. Increase the utilization factor of the plant, eliminate the need for a pool, reduce the land occupation, and save space;nU9Cooling tower noise reduction treatment manufacturer

  5. Small footprint, convenient equipment, movement and placement, and compact structure;nU9Cooling tower noise reduction treatment manufacturer

  6. Convenient operation, stable operation and high degree of automation;nU9Cooling tower noise reduction treatment manufacturer

  7. Save operating costs, actively switch multiple modes, and intelligently control;nU9Cooling tower noise reduction treatment manufacturer

  8. It has a wide range of uses, and can directly cool the medium that does not corrode the heat exchanger; ☆The operating cost of the whole life is low, the initial investment is high, and the operation and protection cost is low.nU9Cooling tower noise reduction treatment manufacturer

  Precautions for the use of closed cooling towers:

  1. Check before operation, such as the basic dimensions of the tower, the elevation of the main components, the control equipment, anti-freezing measures, the hydraulic tightness of the pipes and pools, the end of the motor, current and voltage; the condition of the fan-the level of the blades , The size and difference of the angle of the equipment, the size and difference of the gap between the tip of the blade and the inner wall of the air duct, whether there is debris in the water distribution system, whether the nozzle equipment is firm, the belt tightness of the reducer, the lubricating oil level of the gear reducer, etc. Wait.nU9Cooling tower noise reduction treatment manufacturer

  2. The management staff and cooling towers should be managed by special personnel, and their staff should be professionally trained and hold a qualification certificate. There should be corresponding operating procedures, viewing records, diaries, etc.nU9Cooling tower noise reduction treatment manufacturer

  3. Static balance experiment should be done after tower protection, fan overhaul or blade replacement. After the equipment, check from the beginning according to the check method before operation; check the motor and reducer as above; check the water distribution system as above. Check if the packing is in place, clean and clean.nU9Cooling tower noise reduction treatment manufacturer

  4. The tower's anti-icing measures can stop part of the cooling tower fans; the fans can be reversed at low speed; all or part of the hot water directly enters the pool without passing through the cooling tower; design component area water distribution.nU9Cooling tower noise reduction treatment manufacturer
