Problems solved by technology

[0004] The present invention provides a defoamer for leachate and a preparation method thereof, which can effectively solve the problem that the amount of defoamer used to treat leachate is relatively large, but the defoamer has high activity cost and weak dispersion ability. The effect of defoaming cannot be exerted to a large extent, resulting in the problem that the activity of defoaming agent is not high and the use effect is reduced

Abstract

The invention discloses a defoaming agent for leachate, which comprises an active component with foam breaking capacity, an emulsifier for emulsifying the defoaming agent, a carrier for helping the active component to disperse, an emulsifying aid for helping emulsification and a solvent for helping dissolution, and the raw materials of the active component comprise higher alcohol, glycerol and epoxypropane. The emulsifier comprises the following raw materials: nonylphenol polyoxyethylene ether and polyethylene glycol distearate, the carrier comprises the following raw materials: organic hydrocarbon and aromatic hydrocarbon, a proper amount of glycerol and epoxypropane are added into the active components of the defoaming agent, and the dispersity of the defoaming agent in liquid is improved through the dispersing performance of the glycerol, the epoxypropane improves the activity of the high-carbon alcohol, so that the high-carbon alcohol can be quickly and uniformly dispersed in the to-be-treated liquid after being added into the to-be-treated liquid, foam in the to-be-treated liquid is broken, the activity of the high-carbon alcohol is improved, defoaming can be performed more quickly, the defoaming time is saved, and the defoaming efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of defoamers, in particular to a defoamer for leachate and a preparation method thereof. Background technique [0002] Higher carbon alcohols are linear molecules with strong hydrophobicity and weak hydrophilicity. They are effective defoamers in water systems. They are tested in aqueous solutions of anionic, cationic and nonionic surfactants. It is proposed that the defoaming effect of alcohols is different from that in The solubility in the foaming liquid is related to the degree of diffusion. C7-C9 alcohols are the most effective defoamers. C12-C22 high-carbon alcohols are prepared with the help of appropriate emulsifiers with a particle size of 4-9um and a content of 20-50%. The water emulsion is the defoamer of the water system, and some esters, such as phenylethyl alcohol oleate and lauryl phenylacetate, have defoaming effects in penicillin fermentation, and the latter can also be used as precursors; ...
