FRP cooling tower
The glass fiber reinforced plastic cooling tower adopts countercurrent gas heat exchange technology, and the filler is made of high quality modified poly (ethylene chloride) wave plate to diffuse the water area. Jiangsu anticorrosion engineering company has made some improvement on the design of this series of products, making it more reliable, durable and easy to assemble.
Advantages of FRP cooling towers
Corrosion resistance, high strength, light weight, small size, small footprint, beautiful and durable, and transportation, installation and maintenance are more convenient. 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. So that the cooling effect, energy consumption and noise to achieve an optimized system effect.
Structural characteristics of glass fiber reinforced plastic cooling tower
1 tower body: ZXN cooling tower body made of FRP composite material. 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 treated by the hot dip galvanizing. He used a large number of injection molding components, corrosion resistance, high strength, light weight, good versatility and easy assembly..
2 core packing: heat dissipation film, heat dissipation coefficient, water flow distribution in the plate surface is good, water vapor flow over the surface when the board is too large, so that the ZXN cooling tower to obtain higher heat dissipation.
3 Fan: the large chord, space warps, forward type blade cooling tower fan special. Low speed drive, out of the water noise, to prevent splashing water droplets. Good corrosion resistance, water permeability and durability. The wind speed is uniform, the driving force is low, the efficiency is high, the power consumption is low, the fan runs smoothly and the noise is low. When the seasons change or the process conditions change, the method of changing the blade installation angle can be adopted to meet the technical requirements and improve the equipment efficiency.
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 special motor, good waterproof performance, can be safely used in the cooling tower moist environment.
6 special silencer: special nylon silencing material to reduce noise. Jiangsu FRP cooling tower manufacturers
Performance parameters of glass fiber reinforced plastic cooling tower
ZXN series standard design conditions:
Inlet water temperature: t1=37
Tower water temperature: t2=32 C
Wet bulb temperature: WBT=28
Dry bulb temperature: =38.1
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.
Specification for installation of FRP cooling towers
1 the size of the pipe should be selected according to the size of the tower body, excessive waste of materials, too little impact;
2 pump and outlet pipe installation should be lower than the normal operation of the water level of the water table;
3 more than two cooling towers and use, but only with a pump, the water plate needs to be equipped with a connecting pipe, so that the water tower with the same water level;
4 pump head selection should meet the technical requirements;
5 more than 30% of the nominal amount of water intake should be considered when the size of the water pipe;
6 according to customer requirements, within a certain range of adjustment of the outer pipe layout.
FRP cooling tower installation site
Bearing capacity of the cooling tower and the safety factor of the 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 substations, boilers and other heat sources. Keep away from fire.
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 cooling tower is widely used in various sectors of the national economy. It is especially suitable for the cooling water circulation system of air conditioning, refrigeration, air compressor station, heating furnace and condensation process.
FRP cooling tower notes
1 the direction of the inlet and outlet pipe of the small counter current tower can be selected at any level, but not in the collision. In the middle of the foundation, the load should be 25% of the running weight, the rest of the average by the periphery of the base on the basis of the average, such as the installation of the roof should be considered additional pressure caused by the load.
2 cooling tower and the inlet and outlet pipe should be connected to the stent, to prevent excessive weight pressure on the tower wall.
3 fan blades should be adjusted before installation and use. 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 the height reached consistent is qualified.
4 motor wiring to seal the junction box, and note that the current test value does not exceed the motor load current.
