Description
Technical Field
The invention relates to a composite potassium fulvic acid boiler scale remover and a recycling method
Background
Sodium humate, as a component of industrial boiler detergents, has quality requirements in the coal department standard MT/T747. Patent application No. 201310494632.3 discloses a technology for producing sodium humate by using lignite, weathered coal or peat as main raw materials, which comprises a boiler water treatment agent. Considering the aromaticity, molecular weight and condensation limit of fulvic acid, more carboxyl-containing functional groups have better effect, and the application No. 201811209342.9 patent of a green low-phosphorus environment-friendly boiler treatment agent with scale inhibition, descaling, corrosion prevention and oxygen removal uses sodium fulvate to replace sodium humate and uses a phosphorus-containing ethylene diamine tetramethylene phosphonic acid pentasodium compound to enhance the descaling effect, and the performance is stable, but the proportion of the phosphorus-containing compound accounts for 5-30%. Phosphorus elements and compounds are nutrients of soil, fertilizers and the like, algae are inundated due to the fact that water is rich in phosphorus and is not treated, and calcium absorption can be influenced due to excessive phosphorus components ingested by human bodies. Therefore, phosphorus-free products are used in the washing powder and the detergent of the current daily necessities. The phosphorus-free boiler scale remover proposed by Donglian et al is composed of EDTA, soluble barium salt, buffering agent, corrosion inhibitor, reducing agent and hydrochloric acid. Under the action of hydrochloric acid, rust, silicate and carbonate can be dissolved, and the barium salt contained in the descaling agent can dissolve compact calcium sulfate and magnesium sulfate scale, but the problem of recycling water after descaling is not mentioned.
Disclosure of Invention
The composite potassium fulvate boiler scale remover disclosed by the invention is good in scale removal effect, free of phosphorus and capable of being recycled. The compound potassium fulvate boiler scale remover and the recycling method thereof comprise 5-25 parts of potassium fulvate, 10-30 parts of sulfomethylated lignin, 3-10 parts of sodium aspartate, 2-10 parts of urea stearate (R-CO (NH2)2) and 25-80 parts of soft water. The sulfomethylation is carried out by adopting crushed cotton stalks of 200 meshes in 0.5-1.5% HCL, acidifying for 2 hours at 25-35 ℃, and reacting for 3:1 NaSO3 and H2SO4, and preparing sulfomethylated lignin at the temperature of 60-80 ℃ by using a reaction mixture of 1:1 part of urea, 2-15 parts of potassium stearate, sodium aspartate purchased from a company and self-made soft water are matched to prepare the composite scale inhibitor at the temperature of 30-50 ℃. The method comprises the following steps of 1: 2 mass ratio of fulvic acid to potassium carbonate to prepare fulvic acid potassium, wherein the compound fulvic acid potassium is shown as the following formula, and dissolves calcium carbonate, magnesium carbonate and the like in boiler scale,
FA- (COOH)4+2K2CO3 → FA- (COOK)4+2CO2 ═ 2H 2O; FA- (COOK)4+2CaCO3 → FA- (COO)4Ca2+2K2CO3FA- (COOK)4+2MgCO3 → FA- (COO)4Mg2+2K2CO3, urea and potassium stearate are adopted to adjust the pH value 9-11, so that the combined calcium humate, magnesium humate and the like are depolymerized into potassium humate while forming fulvate-urea stearate (FA- (OH) m (COOH) n + R-CO (NH2)2 → FA- (OH) m (COOH) n.R-CO (NH2) 2.
And the potassium fulvate boiler scale remover can be repeatedly recycled, has no harmful heavy metal ions after detection, and can be used as a component of a soil conditioner after being diluted by 3000 times of 1000-fold.
EXAMPLE 1 production of composite Potassium Fulvate Scale remover

The method of claim 1, wherein the pH value is adjusted to 9-11 by using urea and potassium stearate, and the bound calcium fulvate, magnesium fulvate and the like are depolymerized into potassium fulvate while forming fulvic acid-urea stearate (FA- (OH) m (COOH) n + R-CO (NH2)2 → FA- (OH) m (COOH) n.R-CO (NH2) 2.
5. The method of claim 1, wherein the potassium fulvate is recycled in the fulvic acid production line of Xinjiang, which is a member of agro-ecological technologies, Ltd, by subsequent microfiltration with ceramic membrane and nanofiltration with PEG membrane.
6. The process as claimed in claim 1, wherein the potassium fulvate boiler scale remover is recycled, has no harmful heavy metal ions after being detected, and can be used as a raw material of a soil conditioner after being diluted by 3000 times of 1000 times.
