Abstract
High efficiency boiler scale remover provided by the invention, mainly be composited by plant class raw material and mineral substance raw material and chemical industry class raw material, compare with existing chemical detergent, can under the state of boiler operatiopn, use, the scale removal ability is strong, antiscale, favorable rust preventing effect, treated feedwater meets related standards, and the boiler energy consumption significantly descends.
Description
The invention belongs to boiler chemical cleaning technology.
At present, the chemical cleaning method of boiler for example adopts medicaments such as adding phosphoric acid trisodium, sodium hydroxide, yellow soda ash or tannin extract in boiler, and the method that adopts pickling is also arranged.But these methods not only need stop production and carry out, and influence is produced, and descale effect is undesirable, perishable boiler.
The objective of the invention is to develop a kind of new compound scale remover, not only have good descaling and antiscaling rust-proof effect, and accomplish boiler scale removal, do not influence boiler for producing while moving.
Technical scheme of the present invention is: select to contain materials such as tannin, Liquiritigenin, starch and have neutralization, adsorbing plant class raw material, be equipped with mineral substance raw material and chemical industry class raw material, through certain processing technique, be prepared into compound scale remover, and double antiscale, antirust.
One embodiment of the present of invention are: select cyrtomium fortunei 25-50%, Radix Glycyrrhizae 0.1-1%, plant class raw materials such as starch 10-30%; Mineral substance raw material graphite 3～15%, talcum powder Mg5(Si
14O

23-15%; Chemical industry class raw material formaldehyde 0.5-2%, Chinese holly edge acid 2-7%, acetate 2-7%, aniline 0.2-1%, hydrochloric acid 2-6%, sodium-chlor 2-10%, calcium oxide 1-3%, nickelous nitrate 1-3% etc., through mixing, pulverizing, levigate, sieve, pack.In mixing process, must mix stirring in strict accordance with certain method, have an accident with anti-burning.
In above-mentioned example, cyrtomium fortunei contains tannin, meets acidic substance and be hydrolyzed under higher temperatures, produce gallate, bisgallia acid and ellagic acid, calcium, magnesium plasma in same organic acid, mineral acid and the dirt layer form calcium, magnesium salts, and the structure of destruction dirt layer is loosened the dirt layer and come off.Liquiritigenin plays neutralizing effect in the Radix Glycyrrhizae.The dextrin of starch has adsorption, and it is condensed into the floc sedimentation of larger particles with the small-particle that suspends in the feedwater, deposits to be eliminated.The graphite major ingredient is a carbon, chemical property is stable, because the circulation of stove water is taken graphite to boiler inner wall each one, dirt and intermetallic sticking power are reduced, old dirt can come off voluntarily, the softer difficult long-pending furnace wall of tying of new dirt, formaldehyde, aniline and some other organic acid and metallic iron form thin film, play the boiler rust inhibition.
Boiler detergent of the present invention is widely used in the scale removal in situation about not stopping production of various boilers, antiscale, antirust. Through on probation, the scale removal ability is strong, and antiscaling effect is good, nontoxic nothing erosion, and stove water meets GB1576-85 " low-pressure boiler water standard ", the boiler vimala operation, energy consumption significantly descends.
Through online information retrieval from world patent document index database WPI, its result is from 1963-1987 in 25 years in May, the patent documentation of the technology contents of no scale remover of the present invention.
Claims (2)
1, a kind of boiler detergent, its principal character is to adopt the plant class raw material contain tannin, Liquiritigenin, starch and mineral substance raw material, chemical industry class raw material, be prepared from through mixed, pulverizing, levigate, operation such as sieve, have good scale removal, antiscale, rust inhibition.
2,, it is characterized in that said plant class raw material is 25～50% cyrtomium fortunei, 0.1～1% Radix Glycyrrhizae, 10～30% starch according to the boiler detergent of claim 1; The mineral substance raw material is 3～15% graphite, 3～15% talcum powder; Chemical industry class raw material is 0.5～2% formaldehyde, 2～7% Chinese holly edge acid, 0.2～1% aniline, 2～6% hydrochloric acid, 2～10% sodium-chlor, 1～3% calcium oxide, 1～3 nickelous nitrate, 2～7% acetate etc.
