Abstract
The invention discloses special dust suppressor for a bin for calcined coke finished products and a preparation method for the special dust suppressor. The dust suppressor is prepared with raw materials including, by weight, from 2 to 9% of polyacrylate aqueous emulsion, from 0.15 to 0.5% of sodium polyacrylate, from 0.7 to 2.2% of modified starch, from 5 to 8% of emulsification dispersing agent, from 19 to 29% of mineral oil and from 52 to 68% of water, wherein the molecular weight of the polyacrylate aqueous emulsion ranges from 1000 to 1400, and cyclic acid, butyl acrylate, acrylamide, 2-acrylamide-2-methyl propanesulfonic acid and sodium acrylate are reacted to obtain the polyacrylate aqueous emulsion. When the special dust suppressor is atomized and sprayed on surfaces of calcined coke particles in the bin for calcined coke finished product and atomized and sprayed on polluted air, a similarly netted structure with high adhesion can be formed. Dust can be adhered with each other, accordingly, particle dispersion and drifting of the dust are effectively suppressed, and the special dust suppressor is a product capable of effectively suppressing particles of calcined coke dust.
Description
Technical field
The present invention relates to the dust-inhibitor in environment protection and labour hygiene field and preparation method thereof, particularly relate to and forge special-purpose dust-inhibitor of the burnt finished product bin in back and preparation method thereof.
Background technology
Airborne dust is to be dispersion medium with gas, solid-state trickle the dispersion coefficient that material is a disperse phase.The airborne dust formative factor mainly is: 1, and dust source is dry, surface particles is diminished and powdered; 2, dust source is in exposed and natural weathered state; 3, the extraneous no windproof retention device of dust source receives windage.Common dust mainly is made up of Industrial buildings dust, mineral microparticle, dust particle, biological residual karyomicrosome and domestic refuse dust etc. jointly.The dust emission of its generation is relevant with multiple factor, like size distribution, water cut, atmospheric moisture, wind speed, materials flow amount and drop etc.After dust produces, under driving, the air-flow in environment around the dirt source, diffuses to form dust pollution.Because the major cause of airborne dust is the fine particle in dirt source, have the attribute that suspends very easily aloft, thereby; To above-mentioned situation; The key of catching fine particle to meet factors vary such as outside air humidity, wind speed, materials flow amount, drop and suspending adopts technological means that the absorption of dust fine particle is bonded together, and effectively it is controlled; Make it no longer free, can stop and reduce airborne dust.
In industrial production, various powders are to use the most a kind of material forms, comprise coal coke, forge back Jiao etc.; But in its stacking and transportation; Because the effect of jolting of transportation means or the mobilization of air cause dust from flying, this has not only caused serious environmental pollution through regular meeting; Also can cause the serious waste of resource, even also can cause some production safety accidents.Forge the burnt finished product bin in back usually because the jolting and transfer the drop in the process of travelling belt, operation place air dust content is very high, pollutes very serious.The operating personnel wears special-purpose dust respirator usually; Avoiding dust infringement, but the visibility meter in operation place is very low, if therefore can develop a kind of dust-inhibitor; Its atomized spray is being forged burnt particle surface in back and atomized spray in air; Make forge the back burnt particle form a kind of metastable surface texture, airborne dust be adsorbed be deposited in forge the back burnt particle on, will address this problem to a great extent.
There are various dust-inhibitors to be developed now; Forge the actual needs that back coke powder dirt suppresses but all can not satisfy; If any the aqueous solution of volatile-resistant substance such as spent glycol, Ucar 35; This system can suppress slight airborne dust to a certain extent, can be applied in the environmental sanitation field, but its solid dirt effect is quite faint; What have utilizes the styrenic material, obtains the dust suppression of latex shape material through letex polymerization, and when this system was used for the dust suppression field, addition was bigger, therefore is restricted.It is main body that some other system is to use water miscible Z 150PH; Cooperate some tensio-active agents to constitute, this material toxicity is less, but when it uses; Can become the polymeric membrane of hard within a short period of time; This is comparatively suitable for the less powder body material of particle, and for the bigger material of particle, its effect that prevents airborne dust is very limited.
The invention provides a kind of system that is the main body with MO, acrysol; It is under the situation of very little addition; Forge back burnt particle surface and atomized spray in contaminated air the time when being atomized to be sprayed at; Can form a kind of reticulated structure, thereby satisfy the existing needs that airborne dust and dust suppressed when forging the burnt particulate transportation in back, transfer and stacking with fine adhesion property and strong viscosifying power.
Summary of the invention
The purpose of this invention is to provide a kind of special-purpose dust-inhibitor of the burnt finished product bin in back and preparation method thereof of forging.This dust-inhibitor atomized spray is in contaminated air; But active adsorption is forged the burnt small dust in back; After forging burnt particle top layer, back, form quasi-network structure simultaneously with certain cohesive force; It can get the dust granules interlocking better, and inspissated strengthens, thereby suppresses dust granules dispersion and migration.This thin film layer does not influence the functions of use of forging the burnt material in back, but has tangible absorption cohesive action and to the dust suppression effect of dust.
The special-purpose dust-inhibitor of the burnt finished product bin in back of forging of the present invention, process by the raw material of following weight per distribution ratio:
MO 19～29%;
Emulsifying dispersant 5～8%;
Acrysol (admittedly containing 40wt%-45wt%) 2～9%;
Treated starch 0.7～2.2%;
