Abstract
The present invention provides a high-efficient boiler descaling agent, which is mainly prepared by the composition of plant raw materials, mineral raw materials and chemical industry raw materials. Compared with the existing chemical descaling agents, the high-efficient boiler descaling agent can be used during boiler operation. The high-efficient boiler descaling agent has the advantages of strong descaling capability and good effect for preventing scale and rust. The treated boiler water conforms to relevant standards, and energy consumption of the boilers is obviously reduced.
Description
The invention belongs to boiler chemical cleaning technical field, is about a kind of boiler detergent.
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, the method that adopts pickling is also arranged, but these methods not only descale effect is undesirable, perishable boiler, and needing stopping production to carry out, influence is produced.
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 that the plant class raw material of selecting to contain tannin, Liquiritigenin, starch is equipped with chemical industry class raw materials such as graphite, talcum powder mineral substance raw material and formaldehyde.
Wherein select the cyrtomium fortunei 25～50% that contains tannin for use, Radix Glycyrrhizae 0.1～1%, starch 10～30%, graphite 3～15%, talcum powder Mg
5(Si
14O
10) (OH)
23～15%, formaldehyde 0.5～2%, Chinese holly edge acid 2～7%, aniline 0.2～1%, hydrochloric acid 2～6%, sodium-chlor 2～10%, calcium oxide 1～3%, nickelous nitrate 1～3%, acetate 2～7%, through mixing, pulverizing, levigate, sieving is prepared into compound scale remover, and double antiscaling and antirust.
With the raw material in the foregoing description through mixing, pulverizing, levigate, sieve, pack, in mixing process, must mix stirring in strict accordance with working specification, have an accident with anti-burning.
In the above-described embodiments, because cyrtomium fortunei contains tannin, under comparatively high temps, meet acidic substance and be hydrolyzed, 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 destruction dirt layer structure loosened the dirt layer and come off; Liquiritigenin in the Radix Glycyrrhizae plays neutralizing effect; The dextrin of starch has adsorption, and the small-particle that suspends in the feedwater is condensed into the floc sedimentation of larger particles, deposits to be eliminated; The graphite major ingredient is a carbon, and chemical property is stablized, because the circulation of feedwater is taken graphite to furnace wall each position, dirt and intermetallic sticking power is reduced, and old dirt can come off voluntarily, softer difficult long-pending the knot on the furnace wall of new dirt; Formaldehyde, aniline etc. form thin film with metallic iron, play the boiler rust inhibition.
Boiler detergent of the present invention, be widely used in various boilers, compare with existing scale remover, have scale removal under situation about not stopping production, antiscale, antirust advantage and effect, through on probation, the scale removal ability is strong, antiscaling effect is good, nontoxic nothing erosion, and stove water meets GB1576-85 " low pressure boiler water quality standard ", the boiler vimala operation, energy consumption significantly descends.
Claims (1)
1, a kind of boiler detergent, principal character is to adopt to contain tannin, the plant class raw material that contains Liquiritigenin, starch, be equipped with graphite, talcum powder mineral substance raw material and chemical classes raw material, wherein: select the cyrtomium fortunei 25～50% that contains tannin for use, Radix Glycyrrhizae 0.1～1%, starch 10～30%, graphite 3～15%, talcum powder 3～15%, formaldehyde 0.5～2%, Chinese holly edge acid 2～7%, aniline 0.2～1%, hydrochloric acid 2～6%, sodium-chlor 2～10%, calcium oxide 1～3%, nickelous nitrate 1～3%, acetate 2～7%, through mixing, pulverizing, levigate, sieving is prepared from.
