Round countercurrent glass steel cooling tower adopts the countercurrent gas heat exchange technology, the use of high-quality filler modified polyvinyl chloride plate, with diffusion water area; by rotating the cloth of water, the water distribution uniformity, enhance the cooling effect. Changshu, Jiangsu zhe Xin anti-corrosion engineering company has made a partial improvement in the shape of this series of products, make it more reliable, durable, easy to assemble.
The round counter current type glass steel cooling tower has the advantages of high corrosion resistance, high strength, light weight, small volume, small occupation, beautiful appearance, convenient transportation, installation and maintenance. ZXN series cooling tower to absorb the advanced design and manufacturing technology of similar products in the United States and Japan, through the test of thermal performance of cooling tower, the test data of comprehensive treatment, according to GB7190-2008, according to calculations of the trapezoidal wave packing volumetric mass coefficient XV, height range to choose the best gas water ratio the best section, water load, gas load and high efficiency packing section. In order to determine the packing volume, and the shape and structure of fluid mechanics and aerodynamics design a comprehensive view of the tower, according to the test to estimate the ventilation resistance, reference fan characteristic curve and test data selection with the fan flow and noise requirements and matching motor. The cooling effect, energy consumption and noise to achieve an optimized system effect.
Structural characteristics of a circular countercurrent glass fiber reinforced plastic cooling tower:
1 towers: ZXN cooling tower body made of FRP composite materials. The surface coating layer is made of the imported raw materials, the color which contains UVS light stabilizer, anti ultraviolet radiation, the bright color, anti-aging, especially long and shiny. All steel parts are galvanized by derusting. Cut him a large number of injection molding components, corrosion resistance, high strength, light weight, good versatility and easy assembly..
2: cooling tower core packing film, heat dissipation area coefficient, the distribution of the surface water in the well water flowing through the relative surface disturbance, the ZXN cooling towers gain higher cooling performance.
3 Fan: the large chord, space warps, forward type blade cooling tower fan special. Low speed drive, the noise of the water, to prevent water droplets splashing. Corrosion resistance, good water permeability, durable. The wind speed is uniform, the dynamic pressure is low, the efficiency is high, the power consumption is low, the fan runs smoothly and the noise is low. When the seasonal change or the change of process condition, the method of changing the angle of blade installation can be adopted to meet the technological requirements and improve the efficiency of the device.
4 automatic water separator with rotary tube type water distribution, water diversion device is composed of a steel tube made of plastic or scaly alloy, durable, cloth with PVC plastic pipe, uniformly spread, low pressure, water loss.
5 low noise motor: the use of fully enclosed cooling tower motor, good waterproof performance, can be used safely in the cooling tower in the humid environment.
6 special silencer felt: special nylon acoustic materials, reduce noise. Jiangsu glass fiber reinforced plastic cooling tower
Performance parameters of circular countercurrent glass fiber reinforced plastic cooling tower:
ZXN series standard design conditions:
Inlet water temperature: t1=37
Temperature of the tower: t2=32
Wet bulb temperature: WBT=28
Dry bulb temperature: =38.1 degrees Celsius.
Atmospheric pressure: P=9.94*104Pa
Cooling tower circulating water turbidity is generally not more than 50mg/L, in the short term to allow no more than 100mg/L.
Round countercurrent cooling tower of glass fiber reinforced plastic piping installation instructions:
1 size should be selected according to the size of tubing over the tower body, excessive waste materials, small effect;
2 water pump and water outlet pipe are arranged below the water level should be the highest position disc during normal operation;
3 and two above the cooling tower, but only with a water pump, a water wheel need other connecting pipes, which is used with high water level;
4 pump head selection should meet the technical requirements;
5 when the water quantity exceeds 30% of the nominal amount of water, the water pipe size should be increased as appropriate;
6 according to customer requirements, in a certain range to adjust the outer nozzle layout.
Selection of appropriate round counter current type glass steel cooling tower installation site:
Ground load, the operating weight of reference cooling tower and the safety factor of design, check the bearing capacity of the installation site.
Environmental conditions:
1 cooling tower inlet between the end and the parallel building the shortest distance is not less than 1.5 times of the.
2 should not be installed in the substation, boiler and other places of heat source. Tower body should be far away from open flame.
3 should not be installed in the presence of corrosive gases, such as chimney beside the spa area.
The application scope of circular counter flow glass fiber reinforced plastic cooling tower is widely used in various sectors of the national economy, especially suitable for cooling water circulation system of air conditioning, refrigeration, air compressor station, heating furnace and condensation process.
Considerations for circular counter current type glass steel cooling tower:
1 the direction of the inlet and outlet pipe of the small counter flow tower can be arbitrarily selected in the horizontal position, but not the foundation of the collision. In the middle of the foundation, the load should be 25% of the operating weight, and the rest of the 75% by the external rectangle based on average, such as the installation of the roof should be taken into account the additional pressure caused by the load.
2 the connection point of the cooling tower and the water inlet and outlet pipe should be provided with a support to prevent excessive weight from pressing on the wall of the tower.
3 fan blades in the installation, before use should be adjusted to maintain the same angle. Method for near leaf area of 150 mm, and each leaf margin of two to make a mark, then by the bottom bracket were measured before and after each blade two edge distance to calculate the difference before and after the leaves this edge, through several adjustments to
