Mechanical atomization evaporation systems are suitable for evaporation ponds and drying ponds, and are particularly ideal for areas in Northwest China with dry climates, low rainfall, and abundant sunshine. Using mechanical atomization evaporation systems to improve evaporation efficiency in evaporation ponds, achieving zero wastewater discharge, has become one of the important solutions for zero discharge due to its low processing cost, speed, and ease of maintenance.

 

 

The Hezhonghonke ParKwater mechanical atomization evaporation system consists of five major systems: filtration, water supply, meteorology, control, and evaporation, to achieve the rapid evaporation treatment of concentrated brine. The concentrated brine is sent to the atomization evaporation system via the water supply system for atomization and evaporation, aided by the meteorological system, filtration system, and control system for automatic adjustment and operation. After being broken down by the atomization evaporation system, the concentrated brine forms 100-400um droplets, which rapidly disperse into the air and evaporate quickly due to sunlight (temperature, humidity), and wind, achieving the purpose of treating the concentrated brine in the evaporation pond. Compared with ordinary evaporation ponds, its evaporation rate is increased by about 10-14 times.

Shatter-type mechanical atomization evaporator impeller

 

The working principle of the shatter-type mechanical atomization evaporator is to use specially designed high-speed rotating blades to repeatedly break up the liquid pumped by the water pump. The water droplets are simultaneously thrown into the air by the high-speed rotation of the impeller, and the evaporation is completed during the process of the water droplets falling.

 

 

Suitable for sites with poor water quality and harsh environments.

 

Through a comparison of centralized atomization evaporators, for high-salt wastewater in evaporation ponds, shatter-type mechanical atomization evaporators are more suitable because the concentrated brine in evaporation ponds has a serious tendency to scale, and evaporation ponds are located in open, windy areas in Northwest China with high suspended solids content. If the atomization evaporator spray nozzle diameter is too small, it easily causes scaling and blockage. At the same time, the environment around the evaporation pond is harsh, and the equipment used on site requires a higher protection level and should be easy to maintain.
With the application of mechanical atomization evaporators, because the water mist will inevitably drift, the impact of the drift process on the surroundings also needs to be determined.

 

 

 

 

 

 

The mechanical atomization evaporation device is equipped with a highly automated meteorological system, which can automatically adjust the atomization according to the weather conditions. Traditional thinking always hopes that the evaporation rate is as high as possible, but this will lead to drift, directly affecting the surrounding ecological environment. Therefore, our process idea is to maintain a stable balance point to achieve excellent evaporation results. For example, with the same variables (external meteorological factors), an evaporation rate of 60% can be achieved at a flow rate of 10 m³/h, instead of 100% at a flow rate of 5 m³/h, unless other variables cause changes. Therefore, this balance point is controlled by the meteorological system. We need to control the drift while ensuring a correspondingly high evaporation rate, so a necessary automatic control system is a favorable measure to minimize environmental impact.

According to the general standards of the US Nuclear Regulatory Commission, the salt deposition rate at a distance of 800m is 1-2 kg/ha.month, which will not have any impact. The actual drift distance of the mechanical atomization evaporator is far less than this standard, so for devices with control measures, it will be a perfect process.

 

 

 

 

 

 

With its advantages of low energy consumption, reliable operation, and high processing efficiency, this system has been widely used in the field of zero discharge of industrial wastewater, successfully helping customers solve problems such as full evaporation ponds and overflow.
The ParKwater mechanical atomization evaporator technology for treating high-salt wastewater has been included in the "2015 Recommended List of Advanced Pollution Prevention and Control Demonstration Technologies" by the Ministry of Environmental Protection of China.
