Description
Technical field
The invention belongs to device cleaning agent preparing technical field, and in particular to a kind of long-acting boiler detergent and preparation method thereof.
Background technology
Boiler is extremely important and increasing in industrial and agricultural production and human lives, and current China singly just has more than 30 ten thousand with regard to low-pressure boiler.Their efficiency is improved in order to by the process of effective boiler feed water and Water quality surveillance, to reach safety, economical operation, being engaged in the scientific worker in terms of boiler has carried out substantial amounts of work, achieve satisfied effect, it is and its main power is mainly processed in the stokehold of boiler water, more for what the work of antiscale in stove was done.It is also carried out improving with the medicine for strictly, processing boiler as protection water source and antipollution requirement are increasingly improved, it is non-chromate series to be turned to by past chromate series.
Existing clean the boiler method mainly has：Manual descaling method, mechanical descaling's method and chemical cleaning method, wherein chemical cleaning method effect are the most notable, and its dissolving situation according to incrustation scale in bronsted lowry acids and bases bronsted lowry can be divided into alkaline process scale removal and acid system scale removal.
What alkaline process scale removal was conventional has Method of Soda and sodium phosphate method.Method of Soda has effect to calcium sulfate incrustation scale and calcium silicates incrustation scale, but lime scale is not worked.Sodium phosphate method, while having certain effect to lime scale.It is but the shortcoming of alkaline process is that the scale removal time is long, and not thoroughly, particularly substantial amounts of in sodium phosphate method to have used phosphorous salts, as phosphorus can directly result in body eutrophication, so as to cause microorganism amount reproduction in water, the oxygen and nutrient substance in luxus consumption water, the ecological environment destroyed in water.Therefore the method is just gradually eliminated.
Acid system scale removal is mainly used in removing lime scale and mixing incrustation scale, but too big using acid amount, and perishable metal, and the scaling operation for being particularly related to a large amount of steel equipments to boiler, oil pipeline etc. limits very big.At present commonly used metal inhibitor is reducing or prevent metal parts to be corroded by acid.When using acid system scale removal, the concentration and the determination using inhibition dosage to acid should be calculated and prepare pickle according to the thickness of incrustation scale, quantity and chemical analysis etc. in boiler.
A kind of Chinese patent 201410435619.5, it is proposed that improved equipment scale remover, its synthesis material is：Four methylenephosphonic acid 6-10 parts of tetramethylenediamine, polyepoxy sodium succinate 3-7 parts, sodium gluconate 2-6 parts, Dexol 4-7 parts, sodium tripolyphosphate 2-5 parts, sodium nitrite 1-5 parts, sodium benzoate 2-6 parts, hydroxyethylidene diphosphonic acid acyl acetic acid 4-9 parts, vinyl bis-stearamides 5-9 part.The invention has the beneficial effects as follows, the equipment scale remover proposed by the invention effectively can be removed to equipment surface, internal rust deposite well, while long action time, being capable of protection equipment for a long time.But, the scale remover is substantial amounts of to have used the phosphorous raw material for having serious harm to water quality, soil, and country has put into effect relevant laws and regulations at present, has carried out strict restriction to the usage amount of phosphorous raw material in chemical industry.Therefore the method has not met requirement of the today's society to environmental protection, is not suitable for carrying out large-scale use.
The content of the invention
For the deficiencies in the prior art, the invention provides a kind of long-acting boiler detergent and preparation method thereof, the scale remover is replaced to the phosphorous raw material commonly used in traditional scale remover using the raw material of environmental protection, the pressure caused to environment during alleviating its preparation and use.The detergent also has long-acting defencive function simultaneously, prevents incrustation scale from assembling again.The maintenance period of the cost and equipment of scale removal operation is reduced, is particularly suitable for the scale removal operation of the equipment such as boiler, oil pipeline, with good economic worth and use value.
Long-acting boiler detergent provided by the present invention is made up of the raw material of following weight portion：
Sodium lauryl sulphate 15-18 parts, sulfamic acid 5-10 parts, dodecenylsuccinic acid 6-12 parts, lignin 6-9 parts, sodium gluconate 8-10 parts, vinyl bis-stearamides 4-9 part, aniline 3-6 parts, polyacrylamide 5-8 parts, ethylene glycol 10-20 parts, sodium carbonate 8-12 parts, water 200-300 parts.
The preparation process of long-acting boiler detergent provided by the present invention is：
（1）Weigh：Various raw materials are weighed according to the parts by weight for having preselected；
（2）Mixing：Sodium lauryl sulphate, sulfamic acid, dodecenylsuccinic acid, lignin, sodium gluconate are dissolved in the water of total weight part, 60-80 DEG C are stirred and heated to 500-800 rev/min of rotating speed, continue stirring 40-50 minutes after reaching assigned temperature.Surplus material is subsequently adding, continues stirring 20-30 minutes；
（3）Cooling：By step（2）Middle products therefrom is depressed as 0.5 standard atmosphere, is cooled to 30-40 DEG C, is kept 1-2 hours, is subsequently cooled to room temperature.Obtain final product required scale remover.
The invention has the beneficial effects as follows：Long-acting boiler detergent provided by the present invention has advantages below：（1）Green pollution-free, which produces, will not produce any harm to environment and human body using process；（2）Scale removal function admirable, can quickly remove the incrustation scale of boiler internal, and can form a protective layer in boiler inner wall after its use, delay the speed that incrustation scale is accumulated again, effectively reduce maintenance cost；（3）Cheap, composition is simple, simplifies, rationally in its material choice, and simple production process, convenience are suitable to large scale investment and use.
