Why evaporate? Evaporation is considered an alternative process to reverse osmosis or chemical desalination in wastewater treatment. One type is natural evaporation ponds (with a slow evaporation rate and large evaporation area), and the other is mechanical evaporation. Natural evaporation is usually limited by site constraints or the cost of evaporation ponds, as well as the expenses associated with environmental cleanup and vegetation damage. Mechanical evaporation can **increase the evaporation rate; for the same pond area, the evaporation rate under mechanical evaporation is more than 16 times that of conventional evaporation ponds. Mechanical evaporators are compact in structure, operate efficiently and stably, and are easy to install and transport. Mechanical evaporation is a low-cost and efficient evaporation method under existing evaporative pond conditions, or it is an evaporation method that can **reduce the area required for new evaporative ponds. Mechanical evaporation – fogging evaporators are used in the treatment of industrial wastewater. High-speed rotating blades propel water mist with a particle size of 20–100 μm into the air, creating a fog layer that facilitates evaporation under natural weather conditions. In this utility model, the evaporator for use in evaporation ponds features an electric motor mounted on a floating platform via support columns; a fan blade is attached to the motor’s power output shaft. A pressure booster pump is fixed below the floating platform, and a water spraying device is mounted on the outer wall of the motor. The pressure booster pump is connected to the water spraying device through pipes, with the outlet of the spraying device located below the fan blade. The beneficial effects of this practical new design are as follows: 1. A pressure-enhancing water pump is used for supplying water, and the outlet of the water spraying device is located below the fan blades; thanks to the action of these blades, the water comes into contact with the surrounding environment for a longer period of time, resulting in an effective evaporation effect. 2. It has advantages such as low project investment, simple operation and management, easy installation and disassembly, and reduced land use, which can fully compensate for the shortcomings of natural evaporation ponds. 3. Installed on the evaporation pond, it enhances evaporation; it can increase the evaporation efficiency by 14 to 30 times, and the area of the evaporation pond required to evaporate the same amount of wastewater can be reduced to 1/10 of the original size. Product features: Evaporation pond sprayers are divided into two types: 1. Vertical sprayers: Installed along the shore of the evaporation pond to atomize and evaporate wastewater. a. Power: 22.5 KW; water evaporation rate: approximately 3 m3 per hour. b. It has high power, a long range, and mature technology. c. 380V mains power; the equipment can be pulled around, enabling flexible and convenient installation. d. Cost-effective. 2. Floating evaporator: The equipment is installed on a floating boat and placed on the surface of the evaporation pond to carry out atomized evaporation. a. Power: 13.2 KW; water evaporation rate: approximately 3 m3 per hour. b. It has low power consumption and strong continuous operation capability; all seals of the equipment are maintenance-free, allowing the device to operate continuously for 10,000 hours without interruption under normal conditions, with maintenance required only once a year. c. The high-speed rotating impeller breaks the water into small droplets with a particle size of 100 μm, forming a mist; evaporation occurs under natural weather conditions, resulting in high evaporation efficiency. d. Installed on the surface of the evaporation pond, at the location where the pond sprayer is placed, to ensure that all unevaporated liquids or pollutants are kept within acceptable limits. Evaporative sprayer systems are used in many fields, including the medical and chemical industries, the petrochemical industry, as well as mining, the food industry, wood processing, the power industry, and urban sewage treatment plants. Achieve centralized PLC control, wireless network monitoring, and remote control. All the equipment is fabricated from national standard 304 stainless steel, which prevents the buildup of dirt on the equipment over time. The equipment models DN20-DN250 cater to various pipeline sizes. The valves are high-pressure butterfly valves available on the market, ensuring long service life and stability. The control system for the automatic valves is based on Siemens PLC systems from Germany, allowing for scheduled backwashing and backwashing based on pressure differences, thus meeting the requirements of different environments. The filter element is made of stainless steel, offering excellent corrosion resistance. Its pores are evenly distributed, providing precise filtering accuracy; it can deliver consistent surface filtration performance for particles ranging from 2 to 200 microns ； It has excellent corrosion resistance, high-temperature resistance, pressure resistance, and wear resistance ； The barrel-shaped filter element provides uniform filtration force, a large filtration area, and a high capacity for filtering water; it can be rinsed repeatedly and thus has a long service life ； The filter element is removable and can be replaced; various filter elements are available for use in different environments and industries, such as coal mines, the chemical industry, power plants, and others ； The standards for process execution are as follows: GB150-98 \"Steel Pressure Vessels\", GB/1900-2000 \"Quality Management Systems\", GB/13306 \"Labels\", GB50221-95 \"Quality Inspection and Evaluation Standards for Steel Structure Projects\", and GB98688 \"Basic Forms and Dimensions of Grooves for Submerged Arc Welding Seams\". The manufacturing processes are carried out in strict accordance with these established standards. Before each product leaves the factory, it undergoes a pressure test at a pressure 1.5 times higher than that used in actual operation, thereby ensuring product quality and laying a solid foundation for the company’s reputation and customer satisfaction.
