Energy saving technology in industrial potassium nitrate production Appropriate chemical industry

there are three kinds of potassium nitrate production process of existing in our country, among them with ammonium nitrate and potassium chloride as the raw material of the ion exchange method is widely, and double decomposition of ammonium nitrate and potassium chloride method, another is nitrate and potassium chloride process.

potassium nitrate factory in double decomposition method, with several energy saving techniques, the double decomposition process has a very important role.

manufacturer direct heating dissolving potassium chloride, potassium nitrate to improve the production process, the steam directly into the mixture, bubbled into steam and potassium chloride mixture liquid heat transfer directly, after the high temperature steam heat into condensed water in the mixture liquid, it just part of the condensate can supplement dissolving potassium chloride required water, makes the mixture liquid temperature rising until boiling. If the demands of condensation water is not enough technology supplement water, can be added to join the condensed water from evaporating process of potassium nitrate, until the mixture meet the requirements of the process solution.

in the air cooling crystallization process stage, potassium nitrate manufacturers use air cooling crystallization process, through a special injection device will be dispersed into water or water membrane potassium nitrate solution, through the fan and the air distribution device will air evenly into the air cooling crystallizer, potassium nitrate solution and good contact with the air flow in the process, happened to spread heat and evaporation heat transfer. Evaporation heat transfer by evaporation of solution is to take away heat, cooling of potassium nitrate solution and precipitation with potassium nitrate crystals.

potassium nitrate manufacturer energy-saving renovation, also for the modification of ammonium nitrate solution, the ammonium nitrate instead of after the evaporation of the solution, the mother liquor directly after the separation of potassium nitrate evaporator evaporation concentration, adding ammonium nitrate solution and ammonium chloride precipitation cooling crystallization.

potassium nitrate manufacturers also to modify two effect evaporation process, the original of the two outer circulation evaporator to two downstream evaporation process, saving energy and reducing consumption obviously, and reduce the corrosion speed of equipment.
