preparation example Construction

[0021] The preparation method of the described aluminum processing waste emulsion demulsifier consists of the following steps:

[0022] (1) Configuration of component A: Dissolve ferric chloride in water so that the mass concentration of ferric chloride is 18-21%, fill it into storage tank A for storage;

[0023] (2) Configuration of component B: Fill the hydrogen peroxide aqueous solution into storage tank B for storage;

[0024] (3) Configuration of Component C: Dissolve formic acid in the remaining water and package it in storage tank C for storage; the remaining water here is the total water consumption minus the water consumption in Component A.

[0025] (4) Compounding and mixing: Mix component A, component B and component C, and after stirring evenly, the demulsifier of aluminum processing waste emulsion can be obtained.

[0026] The raw materials of the present invention are all industrial-grade commercially available products, and the code name of the demulsifier of ...

Embodiment 1

[0032] A kind of demulsifier of aluminum processing waste emulsion, compounded by the raw materials of following percentage by weight: ferric trichloride 6%, formic acid 4%, hydrogen peroxide aqueous solution 10%, the rest is water; Wherein the mass concentration of hydrogen peroxide in hydrogen peroxide aqueous solution is 30%.

[0033] The preparation method of the described aluminum processing waste emulsion demulsifier consists of the following steps:

[0035] (2) Configuration of component B: Fill hydrogen peroxide solution into storage tank B for storage;

[0036] (3) Configuration of component C: Dissolve formic acid in the remaining water, pack it into storage tank C for storage;

[0037] (4) Compounding and mixing: Mix component A, component B and component C according to the...

Embodiment 2

[0040] The difference with Example 1 is:

[0041] A kind of demulsifier of aluminum processing waste emulsion, compounded by the following raw materials in weight percentage: 6% ferric chloride, 4.5% formic acid, 9% hydrogen peroxide solution, and the rest is water; wherein the mass concentration of hydrogen peroxide in the hydrogen peroxide solution is 28%.

[0042] The mixing ratio of component A, component B and component C is 1:1:1.

Abstract

The invention discloses an aluminum processing waste emulsion demulsifier and a preparation method thereof. The aluminum processing waste emulsion demulsifier is formed by compounding of the followingraw materials by weight percentage: 6-7 of ferric trichloride, 9-11 of a hydrogen peroxide aqueous solution, 4-5 of formic acid, and the balance water. Specifically, the mass concentration of the hydrogen peroxide aqueous solution is 28-32%. The aluminum processing waste emulsion demulsifier provided by the invention has the advantages that: 1. among the raw material components, on the one hand,hydrogen peroxide reacts with formic acid to generate high activity hydroxyl; and on the other hand, under the catalysis of ferric trichloride, hydrogen peroxide itself decomposes to generate a largenumber of -OH, H- and HO2- high activity free radicals, the high activity hydroxyl or free radicals reduce the content of long-carbon chain organic matters, thereby greatly reducing the viscosity andsurface tension, emulsified oil is precipitated from water without the formation of oil sludge; and 2. also in the raw material components, the ferric hydroxide precipitate formed by reaction of ferric trichloride and hydrogen peroxide has a coacervation effect on suspended impurities in the waste emulsion, the sludge is basically free of oil and is directly dehydrated, and the sludge amount is about 0.3% of the waste emulsion treatment amount.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to an aluminum processing waste emulsion demulsifier and a preparation method thereof. Background technique [0002] The emulsion is mainly composed of mineral oil, vegetable oil, animal oil, surfactants, additives and water. It mainly plays the role of lubrication, cooling and anti-oxidation in the process of aluminum processing. After being used to a certain extent, it will deteriorate and become waste emulsion. With the rapid development of the aluminum deep processing industry, the discharge of waste emulsion is increasing day by day, which brings great pressure to environmental protection. The COD in the waste emulsion is usually as high as tens of thousands or even hundreds of thousands, and its main pollutants are mineral oil, animal and vegetable oil. After the waste emulsion enters the water, the oily substance floats on the water surface to form an oil...
