Sodium nitrate factory technical transformation of the chloride ion solution - Appropriate chemical industry

sodium nitrate has been widely used in industry application, in the process of sodium nitrate factory production, the evaporation process is one of the most popular operating all kinds of chemical unit operation energy consumption, while sodium nitrate factory in the introduction of equipment, the energy recycling, but still there will be a part of the energy to be recycled.

sodium nitrate manufacturers to continuously improve equipment, recycling evaporation heat, outside circulation evaporator for raw material liquid evaporation concentration, achieve the goal of energy conservation and emissions reduction. Sodium nitrate factory outside in front of the back in use process to increase circulation evaporator, hydrophobic device respectively recycling evaporator export high grade and underused steam condensation water waste heat as heat source, evaporation and concentration, directly to the evaporator condensate recovery circuit is connected to the outside circulation heater on heat transfer, reduce the steam use, improve the product yield.

circulation evaporation and standard evaporator, outside circulation evaporator evaporation of the indoor no heating tube, but the heater as a heating of the evaporator section, which is the standard within the evaporator heating section to evaporation, outdoor evaporation condensation liquid feedstock preheating directly add to the heater.

sodium nitrate manufacturers recycling using external loop evaporation technology at the same time, realize the sodium nitrate solution of waste heat evaporating in addition to the purpose of the chloride ion. Chlorine ion in the concentrate, there are two sources: raw material liquid containing trace amounts of sodium chloride and the characteristics of the conversion process generates a trace of chloride.

sodium nitrate manufacturers to increase circulation evaporator outside, under the effect of evaporation heat to heat up, concentrate directly sent to the crystallization process or overflow liquid raw material storage tank back again after evaporation, the whole solution with chloride ions in the process of will as the outer loop two steam discharge evaporation system, reduce the content of chlorine ion solution, improve the quality of sodium nitrate products.
