Description
The technical field is as follows:
the invention relates to a dispersing agent, in particular to a high-efficiency dispersing agent for special equipment.
Background art:
the existing equipment dispersing agent mainly aims at the dispersion of silt and hard scale in the system, and has poor effect on the dispersion of microorganism slime. Meanwhile, strong acid (such as sulfuric acid, nitric acid and the like) needs to be matched for use, so that the equipment is greatly damaged in the cleaning process, and the service life of the equipment can be even shortened.
The invention content is as follows:
the invention aims to solve the technical problem of providing the high-efficiency dispersing agent for special equipment, which has good cleaning effect on hard scale, silt and microorganism slime.
The technical scheme of the invention is that the invention provides a high-efficiency dispersing agent for special equipment, which comprises the following components in percentage by weight:
20-25% of trisodium phosphate;
10-12% of benzotriazole;
10-16% of an isopropenylphosphonic acid-acrylic acid copolymer;
47-60% of water.
Preferably, the composition comprises the following components in percentage by weight:
trisodium phosphate 22%;
10% of benzotriazole;
isopropenylphosphonic acid-acrylic acid copolymer, 15%;
and (4) 53 percent of water.
Further, the detergent is mixed with a high-efficiency special cleaning agent PH-101 according to the ratio of 3:1 for use.
Furthermore, the isopropenylphosphonic acid-acrylic acid copolymer is prepared by taking isopropenylphosphonic acid and acrylic acid as monomers for reaction, wherein the isopropenylphosphonic acid is prepared by taking phosphorus trichloride, acetone and glacial acetic acid as raw materials to synthesize the monomers, and the acrylic acid is prepared by oxidizing propylene by air under the action of a catalyst.
The invention has the beneficial effects that: the dispersant can be suitable for cleaning special equipment, and has good cleaning effect on hard scale, silt and microorganism slime.
The specific implementation mode is as follows:
the invention will be further illustrated with reference to specific embodiments:
the efficient dispersing agent for the special equipment comprises the following components in percentage by weight:
trisodium phosphate 22%;
10% of benzotriazole;
isopropenylphosphonic acid-acrylic acid copolymer, 15%;
and (4) 53 percent of water.
Wherein, trisodium phosphate forms phosphate radical and sodium ion in water, and the phosphate radical reacts with magnesium ion and calcium ion to generate loose water slag, thereby achieving the function of dispersing water scale. Mainly uses industrial soda ash for neutralizing and extracting phosphoric acid as a raw material to synthesize;
the benzotriazole is obtained by reacting phthalic triamine with sodium nitrite;
the isopropenylphosphonic acid-acrylic acid copolymer takes isopropenylphosphonic acid and acrylic acid as monomers to synthesize the isopropenylphosphonic acid-acrylic acid copolymer, and the copolymer has a good calcium ion scale inhibition effect and also has an excellent dispersion effect on iron oxide. The isopropenylphosphonic acid is a monomer synthesized by taking phosphorus trichloride, acetone and glacial acetic acid as raw materials, and acrylic acid is prepared by oxidizing propylene into acrylic acid by air under the action of a catalyst.
Laboratory data comparison of products of the same type
Tube source: the method is characterized in that a Ningbo certain combustion engine electrocoagulator scaling condensation copper pipe is used as an experimental sample, a soaking method (soaking liquid is prepared by matching cleaning agent and dispersing agent) is adopted for experiment, and finally, the weight reduction of a test tube is detected to determine the medicament effect.
Sample source: the commonly used method for matching the cleaning agent and the dispersing agent in the industry comprises the steps of adding the cleaning agent and the dispersing agent according to the mass ratio of 3:1, wherein the adding concentration is 600ppm and 200ppm respectively. The sample includes: a sample No. 1 (a high-efficiency special cleaning agent PH-101 and a high-efficiency special dispersing agent CRX-702); sample # 2 (nitric acid with polymaleic anhydride); sample # 3 (sulfuric acid and BTA); sample # 4 (sulfamic acid and urotropin).
The experimental method comprises the following steps: weighing a plurality of scaling test tubes respectively, adding four samples according to the fixed adding concentration, putting the samples into a reaction device, soaking for 48 hours, drying and weighing, and checking the dissolving effect. The test method refers to a descaling test in HG/T3778-2005 cooling water system chemical cleaning and pre-filming treatment technical rules. Because the condenser pipe is thinner, the test is carried out by adopting a pipeline direct soaking method.
The experimental results are as follows:
remarking: the standard corrosion rate is less than or equal to 0.5 g/(m)2·h)
And (4) experimental conclusion:
through the experimental data, the scale dissolution rate of the product is the same as that of a sulfuric acid formula, and compared with the use of concentrated sulfuric acid, the product has high safety and good safety performance for practical application.
The dispersing agent is used for acid cooler building of titanium white sulfuric acid plantThe high-efficiency special cleaning agent PH-101 is used for cleaning, the using effect is excellent, the temperature difference between the inlet and the outlet of the acid cooler is increased from the original 10 ℃ to more than 15 ℃, and the equipment cleaning loss rate is 18g/m2The following; a system condenser of a certain waste incineration power generation company is matched with a high-efficiency special cleaning agent PH-101 to be cleaned independently, the operation end difference of the system condenser can be controlled to be 10 ℃ under the same operation condition from 15 ℃ originally, and the vacuum degree is improved to 92% from 85% originally.
The dispersing agent obtains better test results in the actual use process, has excellent cleaning effect on special equipment, meets the cleaning requirements of most special equipment, and has better use effect when needing to be matched with the high-efficiency special cleaning agent PH-101. The special equipment referred to in the description comprises a condenser, an acid cooler, a plate heat exchanger and various heat exchange equipment.
