Description
Technical field
The present invention relates to flue gases purification fields, and in particular to a kind of flue gas desulfurization oil removing antifoaming agent and its preparation side
Method.
Background technology
Flue gas desulfurization refer to from coal when combustion of fossil fuel when the flue gas that generates or other industrial waste gases in except desulfuration oxygen
Compound is the maximally efficient and main technological means of control of acid rain and sulfur dioxide pollution.Power-plant flue gas is in production process
Flue dust, sulfur dioxide and the nitrogen oxides of middle generation cause environmental pollution to surrounding area, according to environmental requirement, it is necessary to pollution
Equipment particularly power-plant flue gas administered.Country's means of flue gas desulfurization of power plant is mainly with limestone wet-process FGD sulfur removal technologies at present
Based on, but when boiler coal quality burns the throwing oil operation of insufficient or boiler oil gun, the suction in desulfurizer operational process can be caused
Tower slurries are received by oil pollution, and cause slurries blistering overflow, calcium carbonate granule is wrapped up by oil film, reduces the dissolving of calcium carbonate
Rate, a series of problems, such as so as to cause desulfuration efficiency is low, gypsum dehydration is difficult.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of flue gas desulfurization oil removing antifoaming agent and preparation method thereof.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of flue gas desulfurization oil removing antifoaming agent represents, the antifoaming agent is by polyoxyethylene mountain with weight percentage
Pears alcohol monoleate 10%~20%；Alkylphenol polyoxyethylene ether 10%~20%；Non-ionic 60%~80% group of antifoaming agent
Into.
Above-mentioned non-ionic antifoaming agent is ethylene oxide block aggretion type polyethers or propylene oxide block aggretion type polyethers.
The preparation method of above-mentioned flue gas desulfurization oil removing antifoaming agent, ethylene oxide Sorbitan Monooleate and alkyl phenol are gathered
Ethylene oxide ether is added in reaction kettle, is opened stirring, is heated to 60 DEG C, add non-ionic antifoaming agent, in 60 DEG C of constant temperature
Lower stirring 60 minutes, stops stirring, qualified through chemical examination after cooling, you can filling storage.
The operation principle of flue gas desulfurization oil removing antifoaming agent of the present invention is：Alkylphenol polyoxyethylene ether abbreviation 0P-10 is one kind
Emulsifier, polyoxyethylene sorbitan monooleate abbreviation Tween 80 are a kind of emulsifying solubiliser, 0P-10 and Tween 80 collaboration
Effect can resolve into the oil film for wrapping up calcium carbonate, slurries liquid level oil film and the oil film that is attached on desulfurizing tower and desulphurization plant wall
Very tiny drop and emulsion dispersion is constantly removed in slurries, while non-ionic antifoaming agent can quickly reduce slurries
Surface tension, and eliminate foam and inhibit foam for a long time and generate, so as to control liquid level in desulfurizing tower, prevent liquid in desulfurizing tower
Position virtual height, eliminates slurries overflow.
Flue gas desulfurization oil removing antifoaming agent oil removing of the present invention is thorough, and defoaming is rapid, the suds time is long, acid and alkali-resistance, high temperature resistant；Collection
Oil removing, defoaming and suds function can be widely applied in one in power plant's Wet Fgd By Limestone system.
Specific embodiment
A kind of flue gas desulfurization oil removing antifoaming agent represents, the antifoaming agent is by polyoxyethylene mountain with weight percentage
Pears alcohol monoleate 10%~20%；Alkylphenol polyoxyethylene ether 10%~20%；Non-ionic 60%~80% group of antifoaming agent
Into.Non-ionic antifoaming agent is ethylene oxide block aggretion type polyethers or propylene oxide block aggretion type polyethers.Flue gas of the present invention
Ethylene oxide Sorbitan Monooleate and alkylphenol polyoxyethylene ether are added in reaction by the preparation method of desulfurization oil removing antifoaming agent
In kettle, stirring is opened, 60 DEG C is heated to, adds non-ionic antifoaming agent, stirred 60 minutes under 60 DEG C of constant temperature, stopped
Stirring, it is qualified through chemical examination after cooling, you can filling storage.
The operation principle of flue gas desulfurization oil removing antifoaming agent of the present invention is：Alkylphenol polyoxyethylene ether abbreviation 0P-10 is one kind
Emulsifier, polyoxyethylene sorbitan monooleate abbreviation Tween 80 are a kind of emulsifying solubiliser, 0P-10 and Tween 80 collaboration
Effect can resolve into the oil film for wrapping up calcium carbonate, slurries liquid level oil film and the oil film that is attached on desulfurizing tower and desulphurization plant wall
Very tiny drop and emulsion dispersion is constantly removed in slurries, while non-ionic antifoaming agent can quickly reduce slurries
Surface tension, and eliminate foam and inhibit foam for a long time and generate, so as to control liquid level in desulfurizing tower, prevent liquid in desulfurizing tower
Position virtual height, eliminates slurries overflow.
