1. Product Description

SHNZK series concrete structure counter-flow mechanical-draft cooling tower (ZL 2010 2 0190641.5), a high-tech product developed by our company, gathers years of experience in designing and manufacturing large cooling towers, and integrates the latest technologies in the cooling tower industry at home and abroad,by optimizing the equipment components and the whole design, non-metallization of the internal parts of the tower, streamlining of air flow field, low energy consumption, ultra-low water loss and high quality mechanical ventilation equipment were used,thus dedicated to the owners of a set of beautiful appearance, reliable performance, all-weather operation, long life, low failure rate, low maintenance rate of the leading domestic level of cooling towers.

2. The technology principle

This tower breaks through the traditional design idea of cooling tower, removes the original counter-flow cooling tower's filling part, and makes a significant improvement on the water distribution part, so that the circulating water can form sufficiently small water droplets in the water distribution and water sprinkling area, and the normal water and gas heat exchange can be conducted under the condition of no filling, thus achieving the purpose of circulating water cooling.

3. Product Feature

 The counter-flow hollow cooling tower of SHNZK steel structure avoids the deterioration and damage of filling performance due to water quality, which is of great significance to the treatment of high temperature, high turbidity and easy scale formation of circulating water. It is also widely used in the treatment of circulating water at medium temperature.

 In order to increase the contact area between water and air as much as possible, the counter-current hollow cooling tower of NGZK steel structure adopts atomizing sprinkler head to make the droplet size of the water-sprinkling section less than 1mm, so as to achieve the purpose of heat exchange.

 Therefore, the NGZK cooling tower adopts the arced type drift eliminator. Due to its stable performance, the floating water situation of the hollow tower can be effectively controlled, which greatly affects the surrounding environment and extends the service life of the fan blade.

 The anti-flow hollow cooling tower of NGZK steel structure removes the filling part, which greatly reduces the resistance of the whole tower. The fan's power consumption also decreases correspondingly. The total power consumption ratio of the tower decreases obviously and the economic benefit is remarkable.

 NGZK steel structure counter-flow hollow cooling tower has a large diameter. Due to the technical requirements of spraying, the sprinkler head has 5-6 meters H2O pressure head. Therefore, it is not easy to clog the circulating water sprinkler head with high turbidity.It is suitable for treating the circulating water with high temperature, turbidity and easy scale, which is of great significance for the improvement of cooling tower equipment.

4. Technical Feature

★ Using China Academy of Building Research‘s PKPM software  to do structural design, safe and reliable, stable solid;

★ The process design adopts special software for cooling tower calculation optimization developed on the basis of a large number of experimental data and engineering practice, and is checked by American CTI software, so that the product can operate stably at the best working point and the thermal performance is reliable.;


 Professional process design software

1) Structure Parts

The cooling tower adopts large-span concrete frame structure, and the overall structure has been optimized. On the premise of meeting the standard requirements, the beam and column section is small, which has a significant effect on reducing the wind resistance in the tower body and improving the cooling effect of the tower body.The cast-in-place reinforced concrete frame structure makes the structure itself have good overall stiffness, so that it can effectively resist the influence of vibration during operation and the earthquake action in the seismic zone.

2) Performance

SHN series steel concrete structure counter-flow mechanical ventilation cooling tower has stable performance and high thermal efficiency, which fully meets the requirement of water cooling in industrial circulating water system.

3)Cooling tower anti-corrosion

Hot dipped zinc, UPVC, stainless steel, plastic, FRP and other anticorrosive materials are used in the main pipe, branch pipe, water distribution pipe suspension, nozzle, drift eliminator, fan stack and enclosure casing, and hot dipped zinc anticorrosive materials are used for the steel components in the tower.

4)  Water Distribution System

NGZK steel structure counter-flow hollow cooling tower adopts the pipe type automatic pressure stabilizing water distribution system spray, the pipe in the tower adopts steel band reinforced polyethylene pipe, and the water spray atomizing sprinkler nozzle adopts the opposite sprinkler nozzle.

The paired tangential water sprinkler head is a new type of sprinkler nozzle used in cooling tower pipe water distribution system developed by our company.The arrangement form is composed of two tangential water atomizing sprinkler nozzles, connecting parts and locking device. The sprinkler nozzles are arranged in pairs, and the effluent forms a pair of jet. The arrangement form makes the water droplets of effluent small enough and uniformly distributed.

Tangent water atomization nozzle adopt ABS material, the nozzle in absorbing the old tangent inlet centrifugal nozzle, on the basis of successful technology for nozzle inner cavity of the shell type line is improved, and a diversion cone is added, to make into the nozzle flow movement more rules, the flow field is more reasonable, each point in the flow in the nozzle cavity flow velocity and dynamic pressure, static pressure have more designables, so as to achieve under the condition of low water pressure has good atomization effect, namely the purpose of small water droplets size.
