Description

Coal grain disperse inhibitor mixed thing, preparation method and method of use
Technical field
The present invention relates to a kind of suppressor factor, particularly a kind of coal store or transfer process in prevent that diameter from being disperse the inhibitor mixed thing and the preparation method of phenomenon of the coal grain of 2.5-10 μ m (PM10), belongs to chemical field.
Background technology
In coal storage or transfer process, can produce the particle shape floating substance that is called the dust that disperses in the atmosphere.Store places such as place, coal crushing factory or briquette factory at coal and also can discharge this material.This coal particle that disperses swims in the air usually, is attached on the plant leaf, can bring to growth and development of plants and dislike influence; Invade in the human body through breathing, can be accumulated in the respiratory system, the PM for particulate matter of diameter can be blocked in people's nose outside more than 10 microns; The PM for particulate matter of diameter between 2.5 microns to 10 microns is deposited on the upper respiratory tract usually; Be attached in segmental bronchus and the lung, cause multiple disease, bring harmful effect to human body.
At present disperse the particle countermeasure for water spray or spread water, when temperature reduces, can freeze behind the water spray, can increase danger to the operating personnel on the contrary for the coal between this 2.5 microns to 10 microns; When temperature is higher, need continuous injection, not only can not stop dust fully, also contamination phenomenon may take place because the water evaporation is fast.
Summary of the invention
The object of the present invention is to provide coal store or transfer process in prevent that diameter from being the coal grain of 2.5-10 μ m (PM10) coal of the phenomenon inhibitor mixed thing that disperses that disperses.
The objective of the invention is to realize through following approach:
The coal grain inhibitor mixed thing that disperses, component and mass percent are:
If the content of macromolecular material is less than 0.2 weight %, the adherent coating effect will be small.Specifically, because small to the adherent coating effect of fine coal grain, will reduce the coal grain and disperse and prevent effect, the disperse dispersion stabilization of inhibitor solution of the coal grain that produces also can reduce, so poor effect.In addition, if content surpasses 15.0 weight %, the solution stickiness of manufacturing is too high and have the difficult problem of making, so this method also can not adopt.
If the interfacial activity agent content is less than 0.2 weight %, the emulsification dispersion effect will be small, and when its content surpassed 8.0 weight %, because bubble-related issues will reduce marketability, the divergent function of emulsification simultaneously effect also can play retroaction.
Preferably: the preferred 3.0-10.0% of described macromolecular material, the preferred 0.5-5.0% of described interfacial agent.
Preferably: described interfacial agent is the emulsifying agent or the dispersion agent of negatively charged ion and nonionic system, at least a for verivates such as polyoxyethylene, sorbitanic class, amides and amines.
Preferably: described interfacial agent is at least a of verivates such as sorbitanic monoleate, sorbitanic list dodecyl RATE, dimethyl dodecyl amine oxide, Oleum Cocois alkyl dimethyl amine oxide, coco-nut oil fatty acid diethylolamine and coco-nut oil fatty acid monoethanolamine.
Preferably: described macromolecular material is at least a of semi-synthetic fibre cellulosic material, wetting ability synthesized polymer material or natural macromolecular material;
Described semi-synthetic fibre cellulosic material is Vltra tears (HPMC);
Described wetting ability synthesized polymer material is at least a of CMC 99.5 (CMC), Xylo-Mucine (CMCNa), ECG-505 (CMCCa), methylcellulose gum (MC), hydroxypropylcellulose (HPC), ROHM, ZX-I;
Described natural macromolecular material is at least a of starch, Sudan Gum-arabic, sodium-alginate, DEXTRAN 500.000, guar gum, tracasol.
Preferably: described skimmer is ethanol, organo-siloxane, polyethers, silicon and ether grafting, contain at least a of amine, imines and amides.
Preferably: described developer is Marinco H (MgOH) 2, titanium oxide (TiO 2) or talcum (Talc) is at least a.
Preferably: described wetting agent is at least a of Ucar 35 (PG), butyleneglycol (BG), Sorbitol Powder, glycerine, polyoxyethylene glycol (PEG), sucrose.
The preparation method that the present invention also provides the coal grain to disperse the inhibitor mixed thing, its step is following:
In the aqueous solution, add interfacial agent, wetting agent, skimmer and developer, mix, stirred 15-90 minute along with mixing fully; Temperature increase is arrived 25-40 ℃; Gently splash into macromolecular material this moment, carries out high speed dispersion and stirring about 2-3 hour simultaneously, and stirring velocity is 240-600 rev/min; Room temperature cooling makes the inhibitor mixed thing that disperses of the white coal with stickiness.
The method of use that the present invention also provides the coal grain to disperse the inhibitor mixed thing, its step is following:
In the phenomenon of dispersing more coal taking place stores the field in one's power in the transfer scene; Store and shift on-the-spot operating condition according to coal; Through spraying, spray or spread the water mode and use the coal grain inhibitor mixed thing that disperses; Because factors such as viscosity, polarity and difference in specific gravity distance, mixture are coated the coal grain surface of dispersing and maybe will disperse, and prevent that fine coal grain from dispersing.
Beneficial effect of the present invention is:
1) coal grain of the present invention disperses, and the preparation method is simple for the inhibitor mixed thing, and is easy to operate;
2) macromolecular material that adopts among the present invention is at least a of synthon cellulosic material, wetting ability synthesized polymer material or natural macromolecular material; Carry out rational proportion with interfacial agent; The fine coal grain that can effectively adsorb 2.5-10 μ m (PM10); Prevent the fine coal grain phenomenon of dispersing, reach near resident's and operator's health the comfortable of operating environment and the protection effect with this.
