The study of the evaporation system - potash manufacturer Appropriate chemical industry

potash application is very extensive in the industry, is one of important chemical raw material, widely used in chemical industry, light industry, glass shell of kinescope, pharmaceutical and food industries. Potassium carbonate manufacturers also study of evaporation system, developed is suitable for the evaporation process itself.

in theory, because in the countercurrent flow of waste heat utilization is more convenient, so three reverse flow more reasonable than three-way downstream. Potash manufacturer before the upstream and downstream the comparison calculation, think that the consumption of two kinds of process is very close, then potash manufacturer is found through long-term practice, found that using countercurrent evaporation of equipment corrosion rate is higher, so the potassium carbonate manufacturers to use three-way downstream process.

potash manufacturers adopt triple effect evaporation process of its downstream is focused on the choice of three evaporator, potash producer type of evaporator has central circular tube, hanging baskets, external heating, levin, membrane type and the falling film type. At present, the domestic potash manufacturer mainly adopts rising membrane type and & other L” Type. But after potash manufacturer's study found that these two kinds of evaporator has its own shortcomings, is not completely suitable for evaporation of the potassium carbonate solution. Some potash manufacturer USES the falling film evaporator, the effect of the evaporator is effect a bit better than the above two.

potash factory main consideration of the problem is in the process of production of energy saving and efficiency, are to be decided according to the actual situation, this would require the potash manufacturer long-term experience.
