Abstract
The invention relates to an industrial scale removal method, which comprises the following steps of: preparing 12.0 to 60.0 percent sodium hydrogen carbonate solution, wherein the volume of the sodium hydrogen carbonate solution is equal to 5.0 to 10.0 percent of the volume of a scale removed container; pouring the 12.0 to 60.0 percent sodium hydrogen carbonate solution into the scale removed utensil, fully filling the container with water, stirring the solution for at least 1 minute, heating the solution to the temperature of between 78 and 90 DEG C for the first time, and maintaining the temperature range for over 5 minutes; discharging the solution in the scale removed utensil, and cleaning the container by using clean water; adding anti-scale water into the scale removed utensil, heating the solution to the temperature of between 60 and 85 DEG C for the second time, and maintaining the temperature range for over 10 minutes; and cleaning the scale removed utensil by using the clean water. 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 scaling.
Background technology
The frequency of utilization of utensils such as the boiler in the industry 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 generation is 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 is not if edible rank promptly the scale remover that does not endanger to human body; It is worth more expensive, and the amount of using in the industry is very big again, so the cost of scale removal is just very big; In addition,, how long can produce a large amount of new incrustation scales again, will cause the pollution of environment simultaneously but crossed not even descale effect has reached.
Summary of the invention
In order to overcome the deficiency of prior art, the present invention provides a kind of method of industrial scaling, comprises 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 TR 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 TR above 10min;
5) clean by the scale removal utensil with clear water.
The staple of industry incrustation scale is throw outs such as lime carbonate and Marinco H, and sedimentary kind also has corresponding change according to the purposes difference of industry, and sodium hydrogencarbonate is sodium bicarbonate again, is a kind of weakly alkaline antiacid medicine, can dissolve above-mentioned throw out; Simultaneously; Sodium hydrogencarbonate also is the standing articles for use in kitchen, can be used as the starter of bread, and is edible; Throw outs such as sodium hydrogencarbonate and lime carbonate or Marinco H react; The material that produces can harmful to human yet health, therefore, realize that with sodium hydrogencarbonate scaling can guarantee security.
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, and described sodium hydrogencarbonate 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 by the incrustation scale of scale removal utensil the inside well; Stir 1min at least; Can stir sodium hydrogen carbonate solution, be heated to 78 ~ 90 ℃ first, and keep this TR 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 TR 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 ability 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 staple 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, also can directly use the high waste water of some starch content with starch; Such as steaming waste water behind the sweet potato etc., so more environmental protection.
In order further to realize the method for industrial scaling; Described sodium hydrogen carbonate solution concentration is configured to 25.0 ~ 56.0%; Said 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 scaling ability of component and concentration is stronger.
In order further to realize the method for industrial scaling; Described sodium hydrogen carbonate solution concentration is configured to 52.0%; Said 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 scaling, saidly be heated to 80 ~ 88 ℃ first, and keep this TR and reach 8min, increase heated and boiled between, guarantee to remove incrustation scale fully totally.
In order further to realize the method for industrial scaling, 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 hydrogencarbonate commonly used starting material as scaling, utilizes starch solution configuration antiscale water after the scale removal, utilizes certain density sodium hydrogencarbonate; 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.

Embodiment
Embodiment 1:
It is 3 tons boiler that dirt thickness is about 2.1mm, capacity, and the method concrete steps of industrial scaling below the employing are following:
1) configuration concentration is 52.0% sodium hydrogen carbonate solution 200L;
2) being that 52.0% sodium hydrogen carbonate solution is poured into by in the scale removal utensil with above-mentioned concentration, is 3 tons by the capacity of scale removal utensil, and topped up with water stirs 1.5min, is heated to 84 ℃ first, and keeps this TR and reach 8min;
3) will be cleaned with clear water by after the discharge of the solution in the scale removal utensil, clean as new by the scale removal utensil;
4) in by the scale removal utensil, adding concentration is 0.1% antiscale water, and said antiscale water conservancy disposes with the thick starch in the industry, is heated to 63 ℃, and keeps this TR and reach 19min;
