preparation example Construction

[0020] The preparation method of the seamless steel pipe waste emulsion demulsifier consists of the following steps:

[0021] (1) Configuration of component A: add acetic acid into water to make the mass concentration of acetic acid 28-32%, fill the aqueous solution of acetic acid into storage tank A for storage;

[0022] (2) Configuration of component B: add hydrogen peroxide to the remaining water, fill the aqueous solution of hydrogen peroxide into storage tank B for storage; here, the remaining water is the amount of water in the above raw material formula minus step (1) The amount of water used to mix with acetic acid.

[0023] (3) Compounding and mixing: Mix component A and component B, and after stirring evenly, the demulsifier for waste emulsion of seamless steel pipe can be obtained.

[0024] The mixing mass ratio of component A and component B in the step (3) is 1:1.

Abstract

The invention discloses a seamless steel pipe waste emulsion demulsifier and a preparation method thereof, which is compounded from the following raw materials in weight percentage: 10-12% of acetic acid, 14-16% of hydrogen peroxide, and the rest is water. The advantages of the present invention are: 1. In the raw material components, on the one hand, hydrogen peroxide reacts with acetic acid to generate peracetic acid, which has a highly active hydroxyl group; on the other hand, iron filings and iron oxides in the waste emulsion It reacts with sulfuric acid that adjusts pH to generate divalent and trivalent iron ions, which act as catalysts. Hydrogen peroxide itself decomposes to produce a large number of OH, H, HO2 ▪ highly active free radicals, and these highly active hydroxyl groups or free radicals make long carbon The chain organic content is reduced, thereby greatly reducing the viscosity and surface tension of the emulsified organic components, and the emulsified oil is separated from the water. Due to the loss of viscosity, the oil does not combine with the suspended impurities in the waste emulsion, and no sludge will be formed; 2. Moreover, hydrogen peroxide reacts with ferrous ions to form ferric hydroxide precipitation, which has a coagulation effect on the suspended impurities in the waste emulsion.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a seamless steel pipe waste emulsion demulsifier and a preparation method thereof. Background technique [0002] The emulsion in the process of seamless steel pipe processing mainly plays the role of lubrication, cooling, and anti-oxidation. After being used to a certain extent, it will deteriorate and become waste emulsion. The discharge of waste emulsion in the steel industry has brought considerable pressure to environmental protection. The oil content in the waste emulsion is usually as high as tens of thousands or hundreds of thousands. After entering the water, it will cause the death of aquatic organisms due to lack of oxygen, deteriorate the water quality, and cause environmental pollution. [0003] The waste emulsion of seamless steel pipe is different from the waste emulsion of aluminum processing. The main pollutant mineral oil content in the waste...
