Large Industrial Cooling Tower
Introduction:
The large industrial cooling towers are used in industries to dissipate excess heat from processes that require cooling. They are typically used in power plants, chemical plants, large manufacturing facilities, and HVAC systems for commercial buildings.
​
Models:
-
MRG-E Steel structure series industrial cooling tower
-
MRG-S Concrete structure series industrial cooling tower
-
MRG-FRP FRP structure series industrial cooling tower

Features:
1. Optimized cooling tower pneumatics technology
The internal components of cooling towers are limited by their processing or construction technology, and most of them have square cross-sections. When airflow contacts them, will easily form the eddies and separations, resulting in
large local wind pressure losses. The many local pressure losses causes the resistance of the tower to remain high. "Full-channel flow lined cooling tower technology" is based on the "blade" theory in fluid mechanics. Through the [Cooling Tower Optimization and Analysis System] software, the role of each component in the cooling tower is carefully analyzed, and each component is optimized and selected according to its function, the face velocity and contact surface of each component are treated differently, thereby ensure the optimization of each component and the most advanced of each tower.

2. Kinetic energy recovery fan stack
The fan stack adopts kinetic energy recovery type, and the kinetic energy recovery rate is 30%. The flange connection between the fan stack plates has high rigidity and low height, which accord to the principle of air flow diffusion and has strong wind pressure resistance. The fan stack is equipped with quick-opening inspection door, and the outer surface does not crack and fade. Its surface gel coat adopts imported gel coat, which can resist long-term UV radiation. The fan stack adopts reinforced design, and the wind pressure resistance of the fan stack is not less than 0.6KN/m², which can afford the
attack of typhoons. The fan stack is assembled under the tower and hoisted as a whole, with high rigidity, high strength, stable operation and no vibration.

3. Low resistance and high efficiency water drift eliminator
The water drift eliminator is made of U-PVC material and machine-formed. After forming, the filling thickness≥0.8mm, the water drift loss is≤0.001%, and the oxygen index is ≥30. It will not crack or break at the lowest average month temperature of -23.5℃, and will not soften and deform at an air temperature of 70℃. It has the characteristics of high water collection efficiency, small air flow resistance, high strength, no deformation, easy installation and maintenance, and anti-flaming. The height of the water drift eliminator is minimized during design, so the water drift eliminator is in stable flow field with low air flow velocity, which improves the water collection efficiency and reduces the resistance of the water drift eliminator itself.

4. Water distribution system
Adopt the three-disc nozzle, which use ABS integrated injection molding, has good rigidity and strength, and distributes water evenly when the water density changes greatly in the counter current tower. In the calculation of water distribution uniformity, adopt the mutual conversion theory of dynamic and static pressure, and the simultaneous calculation theory of
along-the-line loss and local loss, and the relationship between the uneven coefficient of single nozzle and the layout method is optimized, so that the total uneven coefficient of water distribution does not exceed 0.3, and the maximum and minimum flow errors of single nozzle do not exceed 5%.
​
5. Convenient and safe maintenance platform inside the tower
There is a maintenance manhole on the top of the tower, a quick-opening door on the fan stack, and a fan maintenance platform. The platform is centered on the fan reducer that requires the most maintenance in the tower. The passage is
connected to the fan stack door and equipped with safety handrail that meet safety standards.
​
6. High-strength panel
FRP panel with strict anti-seepage treatment and reasonable wall flow prevention measures to ensure the beauty and service life of the panel. The reinforcement is the hollow structure with crisscross arrangement to increase the ring stiffness and strength of the component. The basic wind pressure value of the design is 60Kg/m².
​
7. High thermal performance water filling
Adopts trapezoidal wave water-spraying filling. Match the thermal performance and resistance characteristics of this filling type and the best adaptability range make it the first choice for counter current mechanical cooling towers. The filling has large hole diameter and more suitable for the characteristics of poor water quality and high oil content in oil refining circulating water. The water-spraying filling material is U-PVC, and not add recycled materials. The filling is anti-flame, and its oxygen index is not less than 40. The filling is bonded into blocks, and the bonding rate is not less than95%. The final tensile bonding strength of the adhesive is not less than 3.3Mpa. The flat compressive strength of the filling block at room temperature is ≥3000N/m².
​
8. Safe, reliable and energy-saving fan and motor
The fan is produced by famous China manufacturer, with high efficiency, low noise, low vibration and stable operation. It uses FRP blades with adjustable blade angles and reinforced fan adjustment support. The motor is from China famous brand motor manufacturer with protection IP55. It uses the low-noise&energy-saving motor with good sealing and waterproof performance, high temperature resistance and low noise. The reducer has the characteristics of high precision, small size, light weight, large load-bearing capacity, low temperature rise, stable transmission, low noise, low vibration and long service life. The fan support should be equipped with the steel base with epoxy coal tar paint for anti-corrosion.

9. Cooling tower with full safety
Structural design is the core of cooling tower safety. The determination of load is the basis for frame design. This should not only consider the net weight of components, but also the load during operation (wet weight of fillings etc. - water film weight) and the variable load after a period operation (scaling etc permanent loads). The live load on the top of the tower must be considered in the variable load. On the other hand, the necessary margin in processing capacity also is an important guarantee to ensure the safe operation of the device. In terms of parameter selection, The cooling tower not only meets the safety factor required by the specification, but also combines the [Cooling Tower Optimization and Analysis System] software to analyze and determine the rationality and scientifically of the selection for various coefficients to ensure give users satisfied designs and reliable products.
