Abstract
The invention discloses a coal washing water treatment agent and a preparation method thereof. The coal washing water treatment agent is a uniform mixture of cationic starch, calcium chloride and water. The preparation method comprises the following steps of: taking 2.4 to 3.5Kg of cationic starch with the substituted ratio of 0.028 to 0.030 and water in an amount which is two times weight of the cationic starch, stirring in a container, and fully mixing uniformly to obtain starch milk; and adding 20 to 22Kg of calcium chloride into the starch milk, adding water until the mass is 100Kg, making the calcium chloride in the container completely dissolved with stirring, and making the starch form a paste at normal temperature in aqueous solution of calcium chloride to obtain the coal washing water treatment agent. The cationic starch, calcium chloride and water are taken as raw materials and low in prices; and during use, the coal washing water treatment agent can make suspended matters in coal washing water quickly flocculated and settled, and water content in a sedimentation is lower after the suspended matters in the coal washing water are settled.
Description
Technical field
The present invention relates to composition of a kind of coal washing water treating agent, particularly a kind of coal washing water treating agent and preparation method thereof.
Background technology
Contain a large amount of suspended substances in the coal washing water after the coal separation, the overwhelming majority is superfine coal dust in the suspended substance, also has particles such as mineral fine, and coal washing water needs treated isolating just can reach emission standard behind the suspended substance or recycle.Suspended substance in the coal washing water is superfine particle, is difficult to settle down, in order to make coal washing water can reach emission standard or to recycle, need coal washing water is dealt with, when handling coal washing water, need in coal washing water, to add treatment agent, superfine particle flocculation is precipitated, just can isolate suspended substance.In the prior art, the coal washing water treating agent major part is some inorganic salts polymkeric substance, and as polymerize aluminum chloride, poly-ferric chloride etc., coagulant aids generally is a polyacrylamide.These coal washing water treating agent prices are higher, and when handling coal washing water with these coal washing water treating agents, suspended substance sedimentation is slow in the coal washing water, makes the coal washing clarification of water time long, and behind the suspended substance flocculation sediment, water content is higher in the sediment in the coal washing water.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned deficiency, it is lower to propose a kind of price, and when handling coal washing water, suspended substance sedimentation is fast, in the coal washing water behind the suspended substance flocculation sediment, and coal washing water treating agent that water content is lower in the sediment and preparation method thereof.
The present invention is achieved using the following method.
Coal washing water treating agent is the uniform mixture of cationic starch, calcium chloride and water, cationic starch is that substitution value is 0.028 ~ 0.030 cationic starch in the coal washing water treating agent, in the coal washing water treating agent, the weight percentage of cationic starch is 2.4% ~ 3.5%, the weight percentage of calcium chloride is 20% ~ 22%, and all the other are water.
The preparation method of above-mentioned coal washing water treating agent has the following steps:
1. getting weight is cationic starch and a water of 2.4Kg ~ 3.5 Kg, and cationic starch is that substitution value is 0.028 ~ 0.030 cationic starch, and the weight of a water is two times of cationic starch weight,
2. above-mentioned cationic starch and water are placed in the container, under agitation even cationic starch and water thorough mixing, obtain starch milk;
3. getting weight is the calcium chloride of 20 Kg ~ 22 Kg;
4. above-mentioned calcium chloride is put into the starch milk of container;
5. add secondary water in container, making the gross weight of material in the container is 100 kilograms;
6. the calcium chloride in the container is dissolved fully, allow starch gelatinization under the normal temperature in calcium chloride water, obtain coal washing water treating agent.
During use, the present invention is added in the coal washing water, the suspended substance sedimentation in the coal washing water is got off.
The present invention is raw material with cationic starch, calcium chloride and water, and is cheap, during use, the suspended substance rapid flocculation in the coal washing water settled down, and after suspended substance sedimentation got off in the coal washing water, water content was lower in the sediment.
Below in conjunction with embodiment, the present invention is further described.
