Choosing the right evaporation form is a step to prevent plugging. Film evaporator such as falling film evaporator is not suitable for the occasion of crystal generation
1, the choice of evaporation form is a step to prevent plugging, falling film evaporator and other film evaporator is not suitable for the occasion of crystal production, if these occasions using falling film and other film evaporator, plugging is inevitable. Forced circulation evaporator or scraper evaporator should be used on occasions that are easy to produce crystals. Forced circulation evaporator is convenient to operate because of its large evaporation area.
2, that is, the setting of evaporation pipeline is also an important factor to reduce salt, in line with the principle of salt flow and deposition, to ensure that all crystallized salt is collected and discharged from the salt outlet.
