The raw materials are simple, the price is low, the scale removal effect is good, the speed of generating new scales is greatly retarded, and the method is safe and practical.
Description
Technical field
The present invention relates to a kind of method of scale removal, particularly a kind of method of industrial scale removal.
Background technology
The frequency of utilization of industrial utensils such as boiler is very high, and these utensils are difficult to avoid producing incrustation scale or other throw out, and incrustation scale and other throw outs are in case produce, be difficult to clean totally with clear water, and the scale remover of buying on the market, composition is more, costs an arm and a leg, the certain shortcoming of ubiquity on descale effect, if edible rank promptly the scale remover that does not endanger to human body, its value is more expensive, the amount of industrial use is very big again, so the cost of scale removal is just very big; In addition,, a large amount of new incrustation scales can be do not produced how long again, the pollution of environment will be caused simultaneously but cross even descale effect has reached.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of method of industrial scale removal, comprise the steps:
1) configuration concentration is 12.0 ~ 60.0% sodium hydrogen carbonate solution, and described sodium hydrogen carbonate solution volume equals by 5.0 ~ 10.0% of scale removal vessel volume;
2) be that 12.0 ~ 60.0% sodium hydrogen carbonate solution is poured into by in the scale removal utensil with above-mentioned concentration, topped up with water stirs 1min at least, is heated to 78 ~ 90 ℃ first, and keeps this temperature range and surpass 5min;
3) will be cleaned with clear water by after the discharge of the solution in the scale removal utensil;
4) in by the scale removal utensil, add antiscale water, be heated to 60 ~ 85 ℃, and keep this temperature range above 10min;
5) clean by the scale removal utensil with clear water.
The main component of industry incrustation scale is throw outs such as lime carbonate and magnesium hydroxide, and sedimentary kind also has corresponding change according to the purposes difference of industry, and sodium bicarbonate is sodium bicarbonate again, is a kind of weakly alkaline antiacid medicine, can dissolve above-mentioned throw out; Simultaneously, sodium bicarbonate also is the standing articles for use in kitchen, can be used as the starter of bread, edible, throw outs such as sodium bicarbonate and lime carbonate or magnesium hydroxide react, the material that produces can harmful to human yet health, therefore, realize that with sodium bicarbonate scale removal can guarantee security.
Configuration concentration is 12.0 ~ 60.0% sodium hydrogen carbonate solution, described sodium hydrogen carbonate solution volume equals by 5.0 ~ 10.0% of scale removal vessel volume, described sodium bicarbonate is not as can not influencing complete water-soluble the inside yet, described sodium hydrogen carbonate solution is poured into by in the scale removal utensil, topped up with water, the sodium hydrogen carbonate solution of this ratio can be removed well by the incrustation scale of scale removal utensil the inside, stir 1min at least, can stir sodium hydrogen carbonate solution, be heated to 78 ~ 90 ℃ first, and keep this temperature range above 5min, when can quicken to remove incrustation scale, also can make the better effects if of removing incrustation scale; After above-mentioned sodium hydrogen carbonate solution poured out, clean, give by the scale removal utensil to add antiscale water, be heated to 60 ~ 85 ℃, and keep this temperature range and surpass 10min with clear water; , this method can also be slowed down the speed that is produced new incrustation scale by the scale removal utensil except the energy scale removal, that is to say, utilizes method of the present invention can realize having slowed down the speed that is produced new incrustation scale by the scale removal utensil to a great extent after the scale removal.
Described scale removal water main component is a starch solution, can utilize the very high materials of starch content such as Ipomoea batatas or potato to blend and dispose afterwards, can directly dispose solution with starch, also can be directly with the high waste water of some starch content, such as steaming waste water behind the sweet potato etc., so more environmental protection.
In order further to realize the method for industrial scale removal, described sodium hydrogen carbonate solution concentration is configured to 25.0 ~ 56.0%, described concentration is that the volume of 25.0 ~ 56.0% sodium hydrogen carbonate solution equals by scale removal vessel volume 6.0 ~ 8.5%, and so the sodium hydrogen carbonate solution scale removal ability of component and concentration is stronger.
In order further to realize the method for industrial scale removal, described sodium hydrogen carbonate solution concentration is configured to 52.0%, described concentration is that 52.0% sodium hydrogen carbonate solution volume equals by scale removal vessel volume 7.0%, so the sodium hydrogen carbonate solution of component and concentration is suitable for removing the incrustation scale of thickness less than 2.5mm most, can remove incrustation scale fully totally.
In order further to realize the method for industrial scale removal, describedly be heated to 80 ~ 88 ℃ first, and keep this temperature range and reach 8min, increase heated and boiled between, guarantee incrustation scale is removed totally fully.
In order further to realize the method for industrial scale removal, described antiscale water is 0.08 ~ 0.25% starch solution, and so the antiscale water of concentration can further slow down the speed that is produced incrustation scale by the scale removal utensil.
The present invention adopts sodium bicarbonate commonly used starting material as scale removal, utilize starch solution configuration antiscale water after the scale removal, utilize certain density sodium bicarbonate, and follow the purpose that certain step and method realize removing incrustation scale, raw material is simple, and is cheap, features high scale-removing effect, can also slow down the generation speed of new dirt greatly, safe and practical.
