Cooling tower manufacturers talk about the principle and characteristic of evaporative cooling tower

Is the use of water and air cooling tower manufacturer contact, dispersed by evaporation industry or a kind of waste heat generated in refrigeration and air conditioning equipment. The basic principle is: dry ( Low enthalpy) The air after a fan twitch, since the ventilation network into the cooling tower; Saturated steam partial pressure of high temperature water molecules to flow in the low pressure air, hot and humid, High enthalpy) Water from the spray water system into the tower. When water droplets and air contact, on the one hand, due to the direct heat transfer of air and, on the other hand because of the water vapor pressure difference between surface and air, evaporation under the action of pressure, go to the latent heat of evaporation, to take away the quantity of heat of water evaporation heat transfer, so as to achieve the purpose of the cooling. The working process of the cooling tower: the working process of the circular counterflow cooling tower as an example: hot water through independent room pump with certain pressure through pipes, horizontal throat, curved pipes, center of circulation water pressure to the cooling tower water system, water by sowing holes on the pipe evenly spread on packing; Dry low Han value under the action of fan, air into the tower by into the wind at the bottom of the network, formed when hot water flows through the filler surface water film and air to heat, high humidity yoake value out of the hot air from the top, cooling water into the basin, the outlet pipe into the host. In general, into the tower air is dry, low wet bulb temperature of air, water and air obviously exists between the concentration of water molecules and the kinetic pressure difference, when the fan operation, under the action of static pressure inside the tower, the water molecules to evaporate in the air, to become water vapor molecules, the average kinetic energy of the rest of the water molecules will be reduced, thus make the temperature of the circulating water drop. Can be seen from the above analysis, the evaporation cooling and the temperature of the air ( Usually said the dry bulb temperature) Below or above the water temperature has nothing to do, as long as the water molecules can continuously evaporate into the air, the water temperature will be lower. But the evaporation of water into the air will not go on endlessly. When the unsaturated air contact with water, the water molecules to evaporate in the air, but when the air reaches saturation of the contact surface of water and water molecules evaporation not to go out, but in a state of dynamic balance. The evaporated water molecules number is equal to the return from the air with the number of water molecules in the water, water temperature remains constant. Thus it can be seen that, the air is dry contact with water evaporation, the easier it is for the water temperature is easy to reduce. The applicable scope of the < br /> cooling tower < br /> industrial production process of waste heat or cooling process, generally use cooling water to guide will go. Is the role of cooling tower with cooling water of waste heat to heat the air inside the tower, the waste heat to the air and into the atmosphere. For example, within the power plant, boiler heating water into high temperature and high pressure steam, driving steam turbine power generator, the steam turbine exhaust steam after work into the condenser, condenses into water and cooling water to heat exchange, reoccupy water pump back to the boiler circulation use. The process of steam exhaust waste heat to the cooling water, the water temperature, flood waste heat of cooling water, will heat transfer to air in the cooling tower, an evaporative cooling tower from the ram the atmosphere environment. Cooling tower scope of application: mainly used in air conditioning cooling system, frozen series, injection molding, tanning, foaming, electricity, steam turbine, aluminum processing, air compressor, industrial water cooling, and other fields, used more for air conditioning cooling, refrigeration, plastic chemical industry. < br /> < br /> structure in order to save energy and large cooling towers use natural ventilation cooling tower, it consists of ventilator, herringbone column, ring, water spray device and core material. < br /> ventilator for reinforced concrete hyperbolic rotating shell, has good structural mechanics and fluid mechanics properties. Shell bottom edge supported in equidistance V or X to oblique pillars, to form air inlet of cooling tower. Based on load by the oblique pillars to shell. Basis make it cant take more circular foundation under tension by inclined pillar was part of the ring, also can make separation of single foundation or pile foundation. < br /> ventilator throat diameter is small, when calculating the evaporative cooling tower pressure stable shell, shell and thin wall, the diameter increased gradually upward air outlet diffuser, the tower has a rigid ring, below the throat by double curved shape gradually expand, also corresponding section of the shell wall thickening, form a certain stiffness of ring beam. Ventilator also can be combined to make truncated cone shell or conical shell, wood or steel frame outsourcing sheeting or asbestos cement guard polygon tower drum. Germany in ShiMeiHao plant of a height of 146 meters of the structure of cable network is adopted in dry cooling tower, tower drum outsourcing aluminum sheeting, outsourcing aluminum sheeting, has good seismic and wind resistance. < br /> < br /> < br /> < br>
Most people who see a in operation for the first time are amazed at how well the water cooling tower is managed.
