What about the evaporative crystallization process of sodium nitrate?

What about the evaporative crystallization process of sodium nitrate? Xiaobian believes that it is feasible to design a targeted design of the evaporative crystallization scheme of sodium nitrate according to the water quality.

Sodium nitrate evaporation crystallizer system is used to concentrate crystallization and separation of sodium nitrate solution with a preliminary design feed concentration of about 3 to 5% to obtain the required performance indicators of sodium nitrate products.

The design of the sodium nitrate crystallization process should take into account the parameters of the sodium nitrate solution, the parameters of the crystallization solution and the content of sodium nitrate in the solution, the process route of sodium nitrate evaporation crystallization, the evaporator design, and at the same time consider energy-saving measures to reduce the disposable steam consumption, taking into account the water quality of the sodium nitrate evaporation crystallizer and product recovery.

Sodium nitrate using evaporation crystallization process for the selection of the following points:

Sodium nitrate evaporative crystallization process to sodium nitrate wastewater evaporation crystallization, wastewater as raw material, evaporation crystallization after drying to obtain high purity sodium nitrate products.

Evaporator selection:

The process adopts a two-effect forced circulation evaporator, and the design processing capacity is considered at 110%.

The process route is through the process of double-effect forced circulation evaporator, flash crystallization, drying, and packaging to obtain industrial sodium nitrate products.

Sodium nitrate evaporation crystallization process route:

The solution enters the evaporator, the evaporation concentration adopts the two-effect process, the solution is first transported by the pump to the condensate preheater, and then enters the two-effect evaporator, the concentrated slurry concentrated by the two-effect evaporator enters the one-effect evaporator, and the concentrated slurry concentrated by the one-effect evaporator enters the crystallization pool to cool the crystallization. After the one-effect evaporation, the steam enters the two-effect evaporator as a heating heat source, and the concentrated slurry concentrated by the two-effect evaporator is discharged and recovered, and the condensate pump is discharged after the two-effect condensate.

The above is the introduction of the sodium nitrate evaporation crystallization process, the processing amount is different, the design of the evaporation crystallization equipment is slightly different, according to the amount of sodium nitrate solution and the composition of sodium nitrate in the solution for the design process.
