Closed-type cooling tower with small floating rate, closed-type circulating cold water tower

  China trlon air conditioner is a well-known manufacturer integrating R&D, manufacturing and sales of cooling towers. The cooling towers produced can be divided into round, square and combined cooling towers according to their appearance design; according to the specifications, they can be divided into standard, medium temperature, high temperature, water collection, low noise, ultra low noise, and ultra quiet cooling towers. Tower; According to the standard, it can be divided into cross-flow, counter-flow, mixed-flow, open, closed cooling towers, etc. The cooling tower manufactured by our company has beautiful appearance design, reliable product quality, "three guarantees for two years, lifetime maintenance", and credibility guarantee.2x0Cooling tower noise reduction treatment manufacturer

  Closed cooling towers are derived from evaporative coolers. In fact, they are originally a type of heat exchanger that closely combines the characteristics of water-cooled coolers and basic cooling towers. It is also a type of heat exchanger that is between water coolers and air coolers. Therefore, some manufacturers call it "evaporative air cooler". Nowadays, there are many types of this kind of refrigeration equipment. The same feature is spraying water outside the partition heat exchanger and forced natural ventilation. Heat is transferred from the wall surface of the refrigerated fluid in the partition wall heat exchanger to the outside of the wall. The spray water is transferred to the air through the forced convection of the spray water and the air, and the heat transfer of the spray water to the air is mainly composed of the latent heat of the spray water evaporation and the sensible heat exchange between the spray water and the air. . Because the refrigerated fluid circulates in the closed circulation system between the partition wall heat exchanger and the external process equipment, it is different from the general cooling tower where the refrigerated fluid directly contacts the air, so it is called "closed tower" and should be used accordingly.

  The name of the general cooling tower called "open tower" and "closed cooling tower" is more widely used when the refrigerated fluid is water, which is consistent with the cooling tower generally being a cold water tower; when the refrigerated fluid is not a water fluid At that time, it is suggested that the name "evaporative cooler" should still be used, and when the refrigerated fluid changes, it should be called "evaporative cooler".2x0Cooling tower noise reduction treatment manufacturer

  1. Structural characteristics of closed cooling tower2x0Cooling tower noise reduction treatment manufacturer

  The evaporative cooler is a new type of refrigeration equipment that organically combines the sprinkler tube cooler and the circulating system cooling tower, which combines the advantages of the two in one. The cooler adopts counter-flow structure, the key includes blower, axial flow fan, box shell, water collector, water distributor, refrigeration heat exchange pipe group, steel structure frame, wind window, water tank, circulating water pump, water tank float valve, etc. . The cooling pipes are used in series, the heat exchange area is large, and the equipment pressure is small. Compact structure and small footprint. Modular design, single unit use, can be increased or adjusted at will according to equipment production capacity.2x0Cooling tower noise reduction treatment manufacturer

  2. Working principle of closed cooling tower2x0Cooling tower noise reduction treatment manufacturer

  The heat transfer part of the equipment is the heat exchange tube group, and the fluid enters from the bottom end of the heat exchange tube group, and is distributed to each row of tubes through the header, and is discharged from the upper port after heat exchange. The cooling water is pumped to the water distributor at the upper end of the heat exchange tube group. The water distributor is equipped with high-efficiency plugging nozzles to evenly distribute the water to each group of pipes, and the water flows down in a film on the outer surface of the pipes. , And finally fall into the water tank through the filler layer at the upper end of the water tank to realize the adoption of the circulation system. When water flows through the cooler tube group, with the help of the evaporation of water, the latent heat of evaporation of water is used to cool the medium in the tube. At the same time, the fresh air introduced by the axial flow induced draft fan from the wind window around the lower side of the cooler takes away the timeliness of the water vapor, and exerts an advantage for the continuous evaporation of the water film.2x0Cooling tower noise reduction treatment manufacturer

  3. Technical characteristics of closed cooling tower2x0Cooling tower noise reduction treatment manufacturer

  3.1 Adopt counter-flow structure, heat exchange tube adopts serpentine structure, heat transfer tube number is large, heat transfer and air flow range is large, air obstruction is small, heat exchange efficiency is high; the indoor space of the cooler is effectively used, the structure is compact, and it occupies The total land area is small. It can still operate normally in winter when the temperature is low.2x0Cooling tower noise reduction treatment manufacturer

  3.2 The heat exchange tube is a red copper tube, which has obvious heat transfer effect, strong corrosion resistance, and long service life of machinery and equipment.2x0Cooling tower noise reduction treatment manufacturer

  4. Performance indicators and functions2x0Cooling tower noise reduction treatment manufacturer

  4.1 Obvious energy saving effect2x0Cooling tower noise reduction treatment manufacturer

  This cooler has low operating cost, and the cooling temperature changes with the wet bulb temperature. Compared with the shower type or sleeve type cooler, the heat transfer effect is significantly enhanced (the temperature difference between inlet and outlet reaches 60°C); because of the large number of heat transfer tubes, The heat transfer and air flow range is large, and the air obstruction is small (≤10kPa), which can significantly reduce the functional loss of the power equipment; the circulating water pump is assembled on the cooler itself, the pipeline steps are short, and the special anti-clogging nozzle is used, and the water distribution effect Obvious, small obstruction, low pump power, low power consumption; the cooler is a counter-current structure, high heat exchange efficiency, the necessary fan efficiency is low, and the power consumption is low. Compared with shower type or double-pipe type coolers and independently set circulating cooling towers, operating costs can be reduced by 40-50%.2x0Cooling tower noise reduction treatment manufacturer

  4.2 Reliable characteristics, high heat exchange efficiency2x0Cooling tower noise reduction treatment manufacturer

  The heat exchange tube adopts a row tube type, which will not cause blockage from the outside world. It is especially suitable for enterprise applications where the circulating water quality is weak, which is likely to cause corrosion and blockage of the tube heat exchanger. The characteristics are stable and reliable.2x0Cooling tower noise reduction treatment manufacturer

  4.3 Low project investment2x0Cooling tower noise reduction treatment manufacturer

  Because the evaporative cooler integrates heat exchangers, circulating cooling towers, and circulating water pumps, it saves on the purchase and construction of special cooling towers, circulating water pumps, pump rooms, circulating water pipelines, dosing equipment, heat exchangers and other machinery and equipment , Civil engineering and assembly costs. Save project investment by about 40-60%.2x0Cooling tower noise reduction treatment manufacturer

  4.4 Water saving2x0Cooling tower noise reduction treatment manufacturer

  The cooling function of the cooler is to use the latent heat of water evaporation, and the water consumption is small; the use of a low-impedance and high-efficiency water collector prevents the loss of cooling mist. The evaporation damage and discharge in the water cycle account for about 3-5% of the total water flow. If the water quality is good, the water damage is below 2%.2x0Cooling tower noise reduction treatment manufacturer

  4.5 Long service life2x0Cooling tower noise reduction treatment manufacturer

  Use high-quality carbon steel galvanized, reliable application and long life. The fan blades are made of stainless steel, which does not cause erosion.2x0Cooling tower noise reduction treatment manufacturer
