Glass fiber reinforced plastic cooling tower in our country for more than 40 years of development history, industrial recycling water began to appear FRP cooling tower. Nowadays, there are hundreds of glass fiber reinforced plastic cooling towers in China, which have become an important pillar of industrial recycled water and water saving. According to statistics, at present, domestic running tens of thousands of glass steel cooling tower has been facing the requirement of low carbon energy saving, the ongoing technological progress of tower crane itself in many enterprises, the development of energy-saving cooling tower, cooling tower, reducing water lift device to carry out the design of water Taneibu etc..
Glass fiber reinforced plastic dome for natural ventilation cooling tower top air outlet, the height of 3~5 meters, 5~10 meters in diameter, belong to large special-shaped structure. It is made of glass fiber reinforced plastic material, with light weight, high strength, easy installation, corrosion resistance and good diversion effect. The cooling tower, air outlet and guide cover of the domestic cooling tower are all glass fiber reinforced plastics. At present, China's wastewater and sewage emissions increased by 18 tons per year, statistics show that by the end of 2011, China's wastewater discharge has exceeded 640 tons.
With the great demand of water treatment industry for hydraulic glass fiber reinforced plastic products, the products of domestic FRP pipe equipment enterprises are continuously upgraded and basically meet the domestic demand. Large diameter glass fiber reinforced plastic sand pipe has made great contribution to the construction of groundwater network in China during the past 10 years. The water supply and drainage pipe with a diameter of 1 meters or more, highlights the advantages of glass fiber reinforced plastic sand pipe in cost performance, and gradually replaces the concrete tube, ductile iron pipe and steel pipe. In recent years, domestic large glass fiber reinforced plastic water supply and drainage pipelines have formed industrial clusters, and water supply and drainage pipelines have entered overseas markets. At present, the industrial water consumption has increased, and the traditional water treatment methods for wastewater and sewage have been unable to meet the requirements of modern urban water, industrial water and purified water. The adoption of reverse osmosis membrane separation technology abroad is the trend of the times. The treated water has been up to the standard of water purification. Glass fiber reinforced plastic pressure vessel for reverse osmosis water treatment is the key equipment of high performance water treatment technology after the introduction of membrane water treatment technology in China in recent years. This equipment, according to the American ASME standard, is a pressure resistant and fatigue resistant epoxy FRP pressure vessel.
At present, the reverse osmosis water treatment equipment has six major producing areas in China: Jiangsu, South of Jiangsu, Hebei, Hengshui, Dongguan, Shenzhen, Guangdong, Beijing, Shanghai and Harbin. FRP cooling tower is divided into the following major parts: steel skeleton; glass fiber reinforced plastic shell; cooling tower motor / reducer; cooling tower fan; cooling tower water filling; cooling tower water distribution system; cooling tower water collector. The quality of parts has been passed, such as steel skeleton: the material is good or bad, the choice is good, and the choice is cheap. The same angle steel, 3 and 4 prices are different, even the same type of steel, as well as material thickness of the sub - made, product quality is also different; glass fiber reinforced plastic shell: the same resin, the use of different, different prices. Glass steel shell thickness is different, quality is different, the price is different. Glass steel shell thickness is thin, cheap and expensive. The cooling tower has been assembled, but in the course of transportation, the cooling tower motors collapse. The reason why FRP cannot bear the weight of the cooling tower is that the FRP shell is thin and the strengthening is not strengthened.
