Fujianxin XWL air-cooled mist eliminator equipment is an environmentally friendly product developed by the company for the treatment of atmospheric white feathers. The purpose is to improve visual pollution, promote the low-cost compliance of particulate matter, sulfur dioxide, and nitrogen oxide emissions, and even achieve ultra-low near-zero emissions. At the same time, realize the green transformation and development of industrial enterprises such as power, steel, coking and so on.

       The dry-wet combined air cooling tower is a closed cooling device that has both dry-cooling "water-saving" characteristics and wet-cooling "high-efficiency" characteristics. It mainly uses dry-air cooling to achieve water saving. When the ambient temperature is high, it is supplemented by Partial wet cooling, with a small amount of water consumption to achieve lower cooling water temperature requirements. The dry-wet combined air cooling tower takes a critical water spray temperature point as the design boundary condition, organically combines dry air cooling and wet air cooling, and separately calculates and calculates the equipment investment, floor space, and water consumption of dry and wet cooling to achieve water saving. The optimized combination with investment has been widely used in industrial production in water-scarce areas such as Northwest China and North China.

       The plate preheater is a heat exchanger that uses hot blast stove flue gas to preheat blast furnace gas and combustion air. The blast furnace gas and combustion air after heat exchange enter the hot blast stove for combustion, which can increase the combustion temperature by 120～200℃, which can save the hot blast stove fuel, increase the air supply temperature, reduce the blast furnace coke ratio, and improve the strength of iron making. The plate preheater has a high economic value, and the investment cost of the equipment is recovered in about 3 to 5 months.

       The basic principle of the tube (or plate) evaporative air cooler is to use the evaporation of the water film on the outer surface of the tube bundle (or plate bundle) to strengthen the heat dissipation of the outer surface of the tube bundle (or plate bundle), thereby reducing the temperature of the hot fluid in the tube bundle (or plate bundle) the goal of.

       Air compressors are very important equipment in modern industrial production, and are widely used in air separation oxygen production, metallurgy, petrochemical, pharmaceutical, food, paper, glass and other industries. In order to obtain gas with different pressure levels, the compressor is often divided into several stages, and the gas pressure is increased step by step. In order to achieve isothermal compression between the stages, the interstage cooler must be used to reduce the temperature. The gas temperature can generally be reduced from 170°C-140°C to 40°C, and the heat exchange medium is generally water/gas exchange.

       The detachable plate heat exchanger is a new type of high-efficiency heat exchanger made by stacking a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat exchange is performed through half plates. Compared with the conventional shell and tube heat exchanger, under the same flow resistance and pump power consumption, its heat transfer coefficient is much higher, and there is a tendency to replace the shell and tube heat exchanger in the applicable range. The plate heat exchanger is a heat exchanger made by pressing a thin metal plate into a heat exchange plate with a certain corrugated shape, which is then stacked and fastened with plywood and bolts. The working fluid flows through the narrow and tortuous channel formed between the two plates. The hot and cold fluids pass through the flow channel in sequence, with an interlayer plate in the middle to separate the fluid and heat exchange through this plate.
