Cross-Flow Water Cooling Tower
1. The double inlet cooling tower is manufactured through adding a second coil pipe and PVC heat exchange layer to the single air blower system on the basis of one inlet design, so as to achieve better performance and lower energy consumption at the minimum flat area.
2. Double inlet evaporative condenser can reach the maximum industrial capacity with only one module, so the double inlet cooling tower is the ideal choice for large project;
3. Two way coil pipe can achieve the purpose of cooling different medium within a same tower.
Closed cooling tower combines the function of cooling tower and heat exchange together. It reduces the temperature of process fluid till it is close to air wet bulb temperature. When the system works, process fluid for cooling will flow inside of serpentiform coil of heat exchanger. The spray system is outside for moistening coil surface continually. The water spraying on the coil flows to PVC heat exchange layer with efficient cooling effect for cooling. Then, it falls on water collection tray for recycling
I. The main engine of closed cooling tower is composed of parts including shell, heat exchanger, fan, spray water pump, water collector, flume and pipe valve. Closed cooling tower combines the function of cooling tower and heat exchange together. It reduces the temperature of process fluid till it is close to air wet bulb temperature. When the system works, process fluid for cooling will flow inside of serpentiform coil of heat exchanger. The spray system is outside for moistening coil surface continually. The water spraying on the coil flows to PVC heat exchange layer with efficient cooling effect for cooling. Then, it falls on water collection tray for recycling. Meanwhile, the air is sucked and it passes the coil and PVC heat exchange layer so as to make some water evaporated. All moisture in airflow is collected by splash eliminator and then it is sent back to water collection tray. After that, it is evaporated and the heat is carried away from spray water. As a result, the coil and process fluid in the coil are cooled.
2. The new and unique coil design applies serpentiform coil and guarantees certain inclination angle. As a result, when the coil is not used, the medium water in the cooler can be discharged completely so that the coil cannot be frozen after shutdown in winter for users in the north and service life of cooler can be prolonged.
3. There is unique inclination, efficient dehydration and low win resistance dehydrator; this unique patent dehydrator design guarantees efficient dehydration (high evaporation and reduces consumption of spray water) on one hand. It can reduce wind resistance of fan and make the design become more reasonable on the other hand.
In order to guarantee long term and stable operation of closed cooling tower, our company follows perfect ISO9001 international quality assurance system procedure and CTI standard on each link of design, selection, production and purchased parts. We strictly follow all specifications and make products meet design and operation requirements finally.
1. Heart pars of closed cooling tower (cooling tower with deacidified copper tube)
The patented Ark cooler for the closed cooling tower is made of international standard T2 copper tube; all tubes are exposed copper tubes without fins to guarantee cooling effect. It is featured by strong corrosion resistance, small expansion and shrinkage coefficients and high heat transfer performance. Besides, it can resist high temperature environment, resist aging and prevent corrosion. Furthermore, it cannot be softened by organic matter; it cannot be permeated by harmful gas or liquid and it can kill bacteria. Its service life is long.
The international latest and unique coil design applies serpentiform coil and guarantees certain inclination angle. As a result, when the coil is not used, the medium water in the cooler can be discharged completely so that the coil cannot be frozen after shutdown in winter for users in the north and service life of cooler can be prolonged.
2. High strength design
The resistance to wind load of cooling tower body can reach 150Kgf/m2. It can bear the load of Level XII typhoon (wind speed is more than 240km/hour) completely. The resistance to seismic intensity reaches Level VIII.
3. Structure and materials
(1) Shell Galvanized steel sheet
(2) It has adopted the high strength bolt and can adapt to the bad working conditions and it is the ideal building materials of cooling tower to resist the changes of environmental conditions, in the meantime, it can resist the aging caused by the ultraviolet rays and it has strong corrosion resistance to guarantee the comprehensive service life of equipments
(3) The high-performance motor that is specially used for cooling tower shall be specially designed according to the special requirements of closed cooling tower environment proposed by Ark Company. It shall have the characteristics of easy replacement, dismantle, maintenance, long failure free operation, high efficiency, high protection class (IP55) and high insulation class (class F), etc. so as to make the cooling tower operate for long time with low energy consumption in the hot and humid condition of cooling tower.
(4) The precooling packing shall adopt the film packing, and the film flame retardant packing has large heat dissipation area, high thermal performance and it combines the functions of ventilation,and water collecting. It is easy in installation, packing and the installation, dismantle and washing will not destroy the packing so as to prolong its service life.
The PVC sheets are used as the raw materials of packing of Ark closed cooling tower since they have strong freezing resistance, excellent hydrophilicity, thermal performance and corrosion resistance. The packing sheets shall adopt the nonflammable material. It also shall have the best performance in rot resistance, attenuation resistance and biological violation.
It is equipped with efficient water collecting structure to guarantee that the operating drifting rate is no more than 0.001%.
The packing is put on the water tank of equipment in the suspension type for the convenience of dismantle and cleaning.
(5) The water distribution system of closed cooling tower has adopted the gravity natural pool water distribution, the service reservoir shall be flat and the holes shall be smooth, its depth of water shall be 200mm and has the advantages of prevention of blocking and the water distribution is even.
(6) Fan- special low noise fan for cooling tower of low speed and it has adopted the aluminum alloy materials with excellent corrosion resistance and it has good performance and can undertake higher static pressure. It is efficient, energy-saving, stable, and reliable and has the long failure free operation. The fan is designed to operate in low speed and the operation noise is low.
4. Convenience and safety of maintenance
(1) The tower body is equipped with access door, which can flexibly rotate and the spacious and safe maintenance walkway shall be set in the tower.
(2) The Hot-dip galvanized steel ladder shall be set outside the tower for the convenience for the maintenance and overhauling of upper parts of fan and cooling tower.
5. Environmental protection of cooling tower equipments
(1) Control of drifting water
The floating water of cooling tower is one important technical index of environment protection. Therefore, Ark closed cooling tower has adopted the film packing integrated water collector, the hot air will have changes of flow direction for many times in the water collection section according to the special structure of this part and most of the water drops carried in the air flow are captured and it will not affect the surrounding environment.
(2) Noise and vibration control
The special fan for closed cooling tower has the design of low speed operation to guarantee that the cooling tower can operate under the low noise conditions;
The special structure design of film packing can effectively enlarge the area of water film and reduce the noise of drop water. The bottom of packing immersed in the cold water tray and it is under the water level of cold water, the cooling water can consistently flow into the cold water tray in the film form to maximally avoid the voice of flow;
