Abstract
The present invention transforms the method for producing vitriolate of tartar with ammonium sulfate and Repone K.Two kinds of raw materials under promoter effect through once transform, once cooling and once washing, can make two kinds of products of vitriolate of tartar and ammonium chloride potassium simultaneously.In the potassium product, KCE content reaches 50%, and chloride ion content meets import potash fertilizer index below 1.5%.1 ton of vitriolate of tartar of every production consumes 1.0 tons of Repone K and 0.9 ton of ammonium sulfate, simultaneously 0.8 ton of ammonium chloride potassium of by-product.Utilize present method to produce that the vitriolate of tartar tooling cost is low, facility investment is few, energy consumption is low, non-environmental-pollution.
Description
The invention belongs to technical field of inorganic chemical industry, is to be the method for feedstock production vitriolate of tartar with ammonium sulfate and Repone K.
With ammonium sulfate and Repone K is that raw material is produced vitriolate of tartar, the method of prior art is that ammonium sulfate and Repone K and wash water, mother liquor reaction are later obtained ammonium-potassium sulfate and mother liquor, ammonium-potassium sulfate obtains the product vitriolate of tartar through water washing, and unnecessary mother liquor obtains ammonium chloride potassium through dehydration by evaporation.There is the problem of following two aspects in this method, the one, because the vitriolate of tartar that obtains will be through water washing, cause system's mother liquor to expand, solution self can not be kept balance, need evaporation to remove unnecessary moisture content, cause energy consumption excessive, the 2nd, the product vitriolate of tartar quality that obtains through water washing is lower, does not reach the acceptable quality index.
The present invention adopts latest prescription and Klorvess Liquid to wash thick potassium sulfate process and ammonium chloride potassium technology is separated out in the mother liquor cooling, and system's closed cycle need not evaporated, and has fundamentally solved the excessive and product quality problem of energy consumption.
Technical process of the present invention is as follows:
At first ammonium sulfate, Repone K, ammonium mother liquor, potassium washing lotion and reaction promoter (cationic amine compound) are made thick vitriolate of tartar and clear liquor by proportioning (weight) reaction; Clear liquor obtains ammonium chloride potassium and ammonium mother liquor through refrigerated separation, and next recycles the latter; Thick vitriolate of tartar and Klorvess Liquid make wet vitriolate of tartar and potassium washing lotion by proportioning (weight) reaction, and next recycles the potassium washing lotion; Get the product vitriolate of tartar after the wet vitriolate of tartar drying.
The concrete processing condition of the present invention are as follows:
One, thick vitriolate of tartar of preparation and clear liquor
Press Repone K: ammonium sulfate: the ammonium mother liquor: the proportioning of potassium washing lotion=1: 0.5～1.2: 3.5～6: 0.5～2.5 (weight), Repone K per ton adds auxiliary agent (cationic amine compound) 10～200 grams, temperature of reaction is 60～100 ℃, and the reaction times is 0.1～10 hour.
Two, preparation ammonium chloride potassium and ammonium mother liquor
Separable ammonium chloride potassium and the ammonium mother liquor of making when clear liquor is cooled to-10～40 ℃.
Three, preparing product vitriolate of tartar
By thick vitriolate of tartar: the proportioning (weight) of Klorvess Liquid (concentration is 5～25%)=1: 0.5～2.5, under 0～40 ℃ temperature, washed 0.1～10 hour, can obtain wet vitriolate of tartar, wet vitriolate of tartar drying or seasoning promptly get the product vitriolate of tartar.
In the whole technological process of the present invention, the Repone K transformation efficiency reaches 80%, pays product ammonium chloride potassium total nutrient simultaneously and reaches 31%, concentration composite fertilizer requirement in meeting.In the potassium product, potassium oxide content reaches 50%, and chlorion meets import vitriolate of tartar index below 1.5%.One ton of vitriolate of tartar of every production consumes 1.0 tons in Repone K, and 0.9 ton in ammonium sulfate is paid simultaneously and produced 0.8 ton in ammonium chloride potassium.
The present invention than other method have that process procedure is few, flow process is simple, easy to operate, facility investment is few, energy consumption is low, free of contamination characteristics.

Take by weighing 20 milligrams in 450 gram ammonium mother liquors, 150 gram potassium washing lotions, 89 gram Repone K, 102 gram ammonium sulfate, auxiliary agent (cationic aliphatic amide), under 90 ℃ of temperature, mixed stirring reaction 30 minutes, separate obtaining thick vitriolate of tartar 107.5 grams, clear liquor 674.5 grams.Clear liquor is cooled to 30 ℃, obtains ammonium chloride potassium 79.4 grams, ammonium mother liquor 595.1 grams.
With adding 150 grams, 5% Klorvess Liquid in the thick vitriolate of tartar of 107.5 grams, under 30 ℃ temperature, stirred 20 minutes vitriolate of tartar 83.2 grams that must wet, potassium washing lotion 174.3 grams.The vitriolate of tartar that will wet is dried to such an extent that product vitriolate of tartar 79.4 restrains.
