Abstract
The invention discloses a process for producing potassium chloride with a purity above 99 percent. The process comprises the following steps: taking 50 grams of potassium chloride with a purity below98 percent; mixing the potassium chloride with water to obtain saturated potassium chloride solution; arranging a filter tank of a filter sieve on the outlet of a pump; removing insoluble substance ofwater to obtain potassium chloride mother liquor; cooling and crystallizing the mother liquor in a cooling tank; drying the mother liquor by a drying machine to obtain potassium chloride crystal; anddrying the potassium chloride crystal to obtain potassium chloride with a purity above 99 percent.
Description
Technical field
The present invention designs the production technique that a kind of purity is 99% above Repone K
Background technology
High purity chlorination potassium is the important source material of medicine and foodstuff additive, the content requirement of its Repone K reaches more than 99%, the most of manufacturing enterprise of China continues to use traditional thermosol cold crystallization technology always at present, the heat energy consumption of this explained hereafter Repone K is big, equipment corrosion is serious, need import equipment, so the cost height of product.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, it is 99% above Repone K production technique that a kind of purity is provided.
Technical scheme of the present invention is: a kind of purity is the production technique of 99% above Repone K, get purity and be Repone K 50 grams below 98%, add water mix obtain saturated potassium chloride solution after, through add the hay tank of filter sieve at pump outlet, remove the insolubles that anhydrates and obtain the Repone K mother liquor, after mother liquor carried out crystallisation by cooling by cooling tank, dry by drier and obtain potassium chloride, obtaining purity through oven dry at last is 99% above Repone K.
The present invention has the following advantages: pollution-free, rate of recovery height has reduced product cost.
Specific embodiment
Embodiment: a kind of purity is the production technique of 99% above Repone K, get purity and be Repone K 50 grams below 98%, add water mix obtain saturated potassium chloride solution after, through add the hay tank of filter sieve at pump outlet, remove the insolubles that anhydrates and obtain the Repone K mother liquor, after mother liquor carried out crystallisation by cooling by cooling tank, dry by drier and obtain potassium chloride, obtaining purity through oven dry at last is 99% above Repone K.
Claims (1)
