Abstract
The invention provides a cleaning agent for cleaning calcium sulfate scale. The cleaning agent comprises the following components in percentage by weight: 10 to 30 percent of sodium citrate, 0.5 to 5 percent of dodecyl dimethyl benzyl ammonium chloride, 0.5 to 5 percent of sodium di-iso-octyl maleate sulfonate, 5 to 15 percent of absolute ethanol and 45 to 85 percent of reverse osmosis water. Thecleaning agent for the calcium sulfate scale is particularly used for removing insoluble calcium sulfate scale, can completely remove the scale, does not corrode metals, is nontoxic to human bodies and is efficient and safe, a medicament is a neutral solution, waste liquid can be safely discharged, and a phenomenon of hydrogen embrittlement can be avoided.
Description
Technical field
The invention belongs to the industrial circulating cooling water processing technology field, be specifically related to a kind of calcium sulfate scale washing agent.
Background technology
In suitability for industrialized production such as well mine salt exploitation conveying, sea water desaltination, oil-gas field development, boiler, usually run into the problem of fouling, the accumulation of dirt layer not only influences heat transfer efficiency, cause heat-energy losses, output reduces, and when increasing production cost, prolonged the production cycle, etching apparatus shortens service life of equipment, jeopardizes safety in production.Therefore, must regularly handle fouling.The kind of common dirt has carbonate deposit, sulfate scale, silicate scale, mixing incrustation scale, ferric oxide dirt, grease etc.At present, the calcium sulfate dirt also has no idea to clean up hill and dale, and the removing of calcium sulfate dirt is still carried out with sodium hydroxide solution long period of soaking or physical method, wastes time and energy, and this is a great problem that the puzzlement incrustation scale is handled always.
Mentioning a kind of calcium sulfate dirt neutral cleaners among the Chinese patent CN101955863A, is that 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid, fatty alcohol-polyoxyethylene ether, solubility promoter, non-ionic polyacrylamide are combined into.Descale effect for the calcium sulfate dirt is fine, but 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid can pollute environment when discharging for containing phosphorus product in the prescription.
The present invention is directed to the calcium sulfate dirt, having developed a kind of is principal constituent with the organic sequestering agent Trisodium Citrate, select that with sequestrant the tensio-active agent dodecyl benzyl dimethyl ammonium chloride of good synergistic effect and permeate agent sodium diethylhexyl sulfosuccinate to be arranged be auxiliary material for use, compositely make neutral calcium sulfate scale washing agent.
Summary of the invention
Technical purpose of the present invention is to overcome the cleaning difficult problem of calcium sulfate dirt, provide and be used for the novel detergent that the calcium sulfate incrustation scale cleans, in actual applications, no matter be boiler or industrial refrigeration cycle water system, can stop effectively or not stop and clean the calcium sulfate incrustation scale, and its descale effect be along with purity increase and the significantly increase of calcium sulfate dirt.Snaking is thorough, and corroding metal is not nontoxic to human body, and highly effective and safe does not produce the hydrogen embrittlement phenomenon, can directly discharge, and is free from environmental pollution.
The present invention removes a difficult problem for solving calcium sulfate, and the technical scheme that adopts provides a kind of chelating, infiltration dispersion agent, makes that the calcium sulphate crystal of structure scatter, and forms the fluffy tiny particle of a kind of white, so that it is with current beyond the discharge system.The raw material of chelating, infiltration dispersion agent is made up of Trisodium Citrate, sodium diethylhexyl sulfosuccinate, dodecyl benzyl dimethyl ammonium chloride, dehydrated alcohol and reverse osmosis water.Wherein the weight percent of each component is as follows:
Trisodium Citrate: 10%～30%;
Dodecyl benzyl dimethyl ammonium chloride: 0.5%～5%;
Sodium diethylhexyl sulfosuccinate: 0.5%～5%;
Dehydrated alcohol: 5%～15%;
Reverse osmosis water: 45%～85%.
Compared with prior art, positively effect of the present invention is:
(1) calcium sulfate there is special efficacy.
(2) the invention belongs to neutral prescription, snaking is thorough, and corroding metal is not nontoxic to human body, and highly effective and safe does not produce the hydrogen embrittlement phenomenon, can directly discharge, and is free from environmental pollution.
