Abstract
Inventia se refera la un procedeu si la o instalatie pentru cristalizarea izohidrica a clorurei de sodiu, cu care se poate produce sare comestibila de înalta calitate, cu granulatie grosiera, omogena si cu consumuri energetice reduse. Procesul de cristalizere se petrece la temperaturi mici (0-15 degree C), fara a se vaporiza o parte din apa de dizolvare. Instalatia consta dintr-un circuit al saramurii care este vehiculata de o pompa si care se satureaza într-un dizolvator, se purifica într-un schimbator de caldura, este racita suplimentar în altul, pentru a intra apoi într-un recipient de cristalizare cu pat fluidizat. Saramura din care se separa cristalele intra în schimbatorul de caldura în care se încalzeste în contracurent cu ceea calda care vine de la pompa de circulatie si apoi încalzirea este completata într-un alt schimbator mic alimentat de o sursa de caldura secundara. Transferul caldurii de la saramura care intra în cristalizator la cea care intra în dizolvator poate fi facuta si printr-o pompa de caldura, respectiv o masina frigorifica.The invention relates to a process and a plant for the crystallisation of isochloride of sodium chloride, which can produce high quality edible salt with coarse, homogeneous granulation and with low energy consumption. The crystallization process takes place at low temperatures (0-15 ° C), without vaporizing some of the dissolving water. The plant consists of a brine circuit which is circulated by a pump and is saturated in a dissolver, is purified in a heat exchanger, it is further cooled to another to then enter a bed crystallization vessel fluid. The brine from which the crystals are separated enters the heat exchanger in which it cools countercurrently with the warmth that comes from the circulation pump and then the heating is completed in another small heat exchanger powered by a secondary heat source. The transfer of heat from the brine entering the crystallizer to that which enters the dissolver can also be done by a heat pump, respectively a refrigerating machine.
