The company is specialized in the production of refrigeration equipment and presses mold heating equipment and other items, is available from the project planning, engineering design, construction, maintenance and refrigeration, control equipment manufacturing and other integrated services, Chuanhui cooling towers, cooling towers, cold water Tower of quality assurance, buy comfortable, at ease. Is the use of an air cooling tower with water contact cooling water device (directly or indirectly). Chuanhui cooling tower water as circulating coolant absorbs heat from the system and discharged to the atmosphere, thereby reducing the temperature of the air column, manufacturing equipment cooling water can be recycled. Applications Chuanhui cooling towers are mainly used in air conditioning cooling systems, refrigeration series, injection molding, leather, foam, power generation, steam turbine, aluminum processing, air compressors, industrial water cooling and other fields, the most widely used for air-conditioning cooling, freezing, plastic chemical industry. Specific division, as follows: A, air temperature adjustment categories: air-conditioning equipment, cold storage, refrigerator or the like; B, manufacturing and processing categories: food, medicine, metal casting, plastics, rubber, textiles, iron and steel plants, chemical industry, petrochemical products, etc.; C, the mechanical operation of the cooling categories: generators, turbines, compressors, hydraulic machines, engines; D, the role of other types of industries ...... Xinliang based cooling tower is to carry the waste heat of cooling water In the interior of the tower air heat exchange, so that heat is transferred to the air and scattered into the atmosphere. Cooling towers are generally constructed Chuanhui cooling tower generally consists of filler (also known as heat wood), water distribution systems, ventilation equipment, air distribution device (such as: air inlet shutters, wind deflector, wind torso), retaining (or close the water ), a sump (or sump), and the like, different combinations of the above-described structure portion may be configured to different types of cooling towers. Principle generic term "cooling tower" is used to describe a direct (open) and indirect (closed) cooling equipment. While most think of a "cooling tower as an open direct contact with the heat sink" indirect cooling tower, sometimes called "closed circuit cooling tower" is but also a cooling tower. A direct, or open cooling tower is sealed inside the structure as a means to distribute it in warm water to feed the labyrinth packing or "fill up." Padding provides a big expansion of aviation, the evaporation of water heated air and interfaces occur. Cooling water, because it is filled out by gravity through falls, and in direct contact with the air across it. In the cooling water, and then collected in a lower than it is from the whole process back to absorb more heat pump cold water basin fill. Heat and moist air leaving the filling full discharge point remote from the air inlet air enough to prevent them from being involved in the cooling tower back. Fill may include a plurality of, mainly vertical, water wet surface upon which the spread of (fill) or landscape elements create a lot of splash has a larger surface area of ??the droplets cascaded several levels film (splash). Indirect, or closed circuit cooling tower does not involve air, liquid, typically water or a glycol mixture in direct contact, it is cooled. The difference is that open cooling tower, indirectly owned by two separate fluid circuit cooling tower. An external circuit water is in the second track, which is outside the process tube bundle heat fluid circulation (closed coil) is connected to the closed circuit is cooled and returned. Air is drawn across the heat cascade water tube through the cycle, providing a similar open evaporative cooling tower. In the operation of the heat from the internal fluid circuit, through a coil pipe wall, an external circuit, and then evaporated by the heated air and some of the water, into the atmosphere. Indirect cooling tower operations, it is very similar to open cooling tower with one exception. This process is the coolant in a "closed" circuit, it is not directly exposed to the atmosphere or external circulating water. In counterflow cooling towers for air travel by filling up or control, directly opposite the water downward. Downward movement in the level of cross-flow cooling tower air moves through the fill water. Cooling tower also has a feature in which the aeronautical mobile means. Mechanical draft cooling tower fan on electricity to attract or forced air tower. High growth in the use of natural draft cooling tower exhaust chimney provides a draft of air buoyancy. Fan-assisted natural ventilation uses mechanical draft cooling towers to increase the influence of buoyancy. Many draft air wind generated by the cooling towers early. If the cooling water from the cooling tower return to reuse some of the water must be added to replace or constitution, that part of the flow of evaporation. Including clean water due to evaporation, minerals and other solid circulating water concentration of dissolved tends to increase, unless some of the dissolved solids control under such combat means available. Some water is lost with the exhaust gas being carried (drift) spray, but this is usually reduced to a very small amount of the bezel-like devices, called drift eliminators, collect droplets. It must be equal to the amount to make up for evaporation, blown down, total drift, such as wind and other water seepage blowout losses, to maintain a stable level. Glossary of useful terms often used in the cooling tower industry: Drift - Water being carried out with the exhaust gas cooling tower droplets. Drift droplets have the impurity concentration of the same water into the tower. Baffles reduce drift velocity usually similar devices, called drift eliminators, through air travel must leave the tower fill and spray zones. Blowout - wind blowing cooling towers, water droplets, usually at the air inlet opening. Water may also be lost, in the case of wind, through splashing or spraying. Such as wind screens, louvers, splash water diversion and deflection adjusting means to limit these losses. Plume - saturated gas stream leaving the cooling tower. Plume is visible when water vapor it contains condenses cool air contact, in human breath fog on a cold day like saturated air. In some cases, cooling towers feathers may spray or jeopardize its surroundings icing. Please note that the water evaporative cooling process is "pure" water, in contrast to the drift in the proportion of very small droplets or water blown air intakes. Blow - circulating water flow is removed, in order to maintain an acceptable level, part of the amount dissolved solids and other impurities. Flowing through the wooden structure of the cooling tower water rinse leaching operations - loss of wood-preserving chemicals. Noise - Sound energy cooling tower emissions and heard (recorded) a given distance and direction. The sound is produced by the impact of declining water quality of the air by the fans of the movement, the movement of the fan blade structure, motors, gearboxes and drive belts. Type Features a cooling tower, countercurrent column 1, the water in the tower fillers, water top-down, bottom-up air, the two flows in the opposite kind of cooling tower. 2, good thermal performance counterflow cooling towers, three cooling sections: ① water distribution to filling the top of the space, the higher the temperature of this paragraph, so still heat to the air. ② packing water and air heat exchange section. ③ filler to a sump space segment watering, water is cooled in this section referred to as "tail effect." In northern China water temperature drop 1-2 ℃. In summary, the countercurrent tower than crossflow towers in the same situation, small packing volume is about 20% higher countercurrent heat exchange tower more reasonable cooling efficiency. 3, clogging water distribution system, water spray to keep clean and not aging filler, reflux little moisture, frost and ice action easier. Multiple designs can be combined winter temperature in the desired amount of water can be combined with a single operation or closed for all fans. 4, construction installation and maintenance easy, low-cost, commonly used in air conditioning and industrial large and medium-sized cooling circulating water. Second, the cross-flow tower l, water tower packing, the water from top to bottom, the flow of air from the tower horizontal flow in a vertical tower two orthogonal A cooling tower. Commonly used in noise demanding residential area, it is air-conditioning sector to use more cooling cycle tower. Advantages: energy saving, low water pressure, wind resistance, also configure the low-speed motor, no dripping noise and wind noise moving, packing and distribution convenient water system overhaul. 2, free to build a foundation with the shape of the building more than one place, respectively, to start single or multiple cooling tower according to the desired temperature. 3, should be noted: a frame to 40% more heat exchange to have more volume filler, filler easy to aging, easy to plug the hole with water, anti-icing is bad, great moisture reflux. Advantages of crossflow towers is the tower countercurrent shortcomings. Third, spray cooling tower without packing ventilation unique spray nozzle is installed in the cooling air inlet at the bottom of the upper part, there is no spin-spray overhead electrical supply and exhaust air in two ways. The hot water produced by the rotation of films in the cyclone formed in the nozzle of the spray fine mist, fog-like existence, also fall upward spray downstream countercurrent two cooling aging. Spray evenly without hollow phenomenon, the cooling effect is stable, low power consumption, leaching rate of 0.01%, no filler, low cost and long life, in line with national standards GB7190.1-1997. Use of metallurgy, food, chemical, high turbidity, temperature, corrosion cooling tower. Fourth, the closed cooling tower 1. Closed cooling tower is a variation and development of traditional cooling tower. It is actually a combination of a cooling tower structure of cooling tower, chiller and a wet cooling tower evaporation, it is a horizontal evaporative cooling towers, process fluid in the pipe flows outward through the air in the tube, the two mutual do not touch. After the bottom of the reservoir water extracted by the circulating pump inside, rushed tube uniformly sprayed down. It is not in contact with the process fluid or refrigerant and the hot water pipe outside air into a closed cooling tower, spray water through enhanced heat and mass transfer effects. 2. Closed cooling tower suitable for high quality requirements of a variety of circulating cooling systems, electric power, chemical, steel, food and many industrial sector applications. On the other hand, compared with the air-cooled heat exchangers, evaporative cooling Tully by latent heat of vaporization of water pipe under the side of the air-side heat and mass transfer significantly enhanced, but also has obvious advantages. Closed cooling tower (also called evaporative air cooler) placed in the tube heat exchanger tower, through the air, spraying water and recycled water heat exchange to ensure the circulation of the cooling effect. Because it is a closed loop, which can ensure the water quality from pollution, well protected and efficient operation of the main equipment to improve the service life. When the outside temperature is low, water spray system can be stopped, play water-saving effect. Push increasingly scarce national energy conservation policy implementation and water resources in recent years, closed cooling tower in iron and steel metallurgy, power electronics, machining, air conditioning systems and other industries has been widely used. Energy-efficient cooling towers northern winter temperatures often below freezing, run antifreeze closed cooling tower problems have become increasingly prominent, if not resolved, could be damaged by frost or cooling tower heat transfer tubes other components. Depending on the process characteristics, closed cooling tower and some winter run all day, and some part time run, some almost not. But we need to consider freezing problems. If the winter closed cooling tower need to run, stop, shall spray water and the inner loop water emptying. Chuanhui CJT series of cooling towers using three-dimensional structure tilted in the design of the heat exchanger to ensure smooth flow of water and emptying clean. Heat exchanger with a valve at the top of the structure, can pass into the air assisted evacuation if necessary. Closed cooling tower, also known as fluid coolers, evaporative coolers.
