High purity industrial potassium nitrate industrial potassium nitrate is an important inorganic chemical raw materials, belonging to the control products, the general appearance of white particles or crystalline powder. In order to prevent the material loss of high purity industrial potassium nitrate_industrial potassium nitrate caused by droplets entrained by air flow, potassium nitrate manufacturers adopt reasonable liquid distribution device and wind speed in air cooling crystallization device. In addition, a liquid catching device is added to control the supersaturation of the solution and accelerate the convective diffusion of the solution during the air-cooled crystallization process, so as to precipitate high-purity industrial potassium nitrate-industrial potassium nitrate crystalline products with large grains.

At the same time, potassium nitrate manufacturers adopt a two-effect evaporation process, changing the original two external circulation evaporators to a two-effect forward-flow evaporation process. During the evaporation process, the steam from the boiler enters the first-effect evaporator for heating and evaporation, and then enters the second-effect evaporator for second-stage steam heating. After the steam and condensate from the preheater are separated by the steam-water separator, the condensate enters the condenser for condensation, and then the vacuum system is vacuumed to maintain the negative pressure in the second-effect evaporator.
The use of energy-saving technology in the process of producing high-purity industrial potassium nitrate by potassium nitrate manufacturers is to use air as the cooling medium without the use of cooling water and steam, thus reducing the loss of energy. There are also large air volume and small power axial flow fans, low power consumption, and potassium nitrate manufacturers using two-effect evaporation process, energy-saving effect is very significant, the corrosion of equipment has also reduced a lot. The use of energy-saving technology greatly reduces the production cost of high-purity industrial potassium nitrate and industrial potassium nitrate, and improves the competitiveness of enterprises.
