Abstract
The invention discloses a kind of coal yard wind-proof dust-suppression agent and preparation method thereof, coal yard wind-proof dust-suppression agent of the present invention is counted by weight, is prepared from by 37 parts of 0.1 0.8 parts of xanthans and maltodextrin, glycerine and propane diols, 0.5 4 parts of polyvinyl alcohol, 1.5 5.5 parts of diethylene glycol, 1.5 2 parts of sodium Diacetate, 10 0.5 1 parts of OP, 100 parts of water.Coal yard wind-proof dust-suppression agent of the present invention has good permeability, caking property, moisture-absorption water-retention, the erosion of wind-force can effectively be resisted by being sprayed on dump, with good anti-dust effect, while the features such as dust suppressant has nontoxic, pollution-free, degradable, easy to use.
Description
Technical field
The present invention relates to technical field of environment pollution control, more particularly to a kind of coal yard wind-proof dust-suppression agent and its preparation side
Method.
Background technology
The energy resource structure of China is based on coal.According to statistics, coal in China usage amount in 2010 reaches 3,000,000,000 tons, to 2020
Year is up to 4,000,000,000 tons, and coal is in the principal mode that recent decades are AND ENERGY RESOURCES CONSUMPTION IN CHINAs.But fire coal is in storing process（Coal
The fields such as ore deposit, harbour, industrial enterprise）In substantial amounts of airborne dust can be produced due to the erosion of wind-force, the environment of surrounding can not only be produced
Raw greatly pollution, and cause the waste of resource.
At present, it is main based on physical method for the Treatment process of coal yard airborne dust, administer airborne dust problem and use following two
The method of kind：1. sprinkle water method, the method for watering adds the water content of coal flow table face or dump surface coal, increases coal particle
Quality, therefore have certain dust suppression effect, but moisture is evaporated quickly, effective dust suppression is held time short, and water consumption is high,
Watering also results in the water content rise of coal, makes the reduction of its low heat valve, reduces the thermal efficiency of boiler, general effect is paid no attention to
Think；2. reach that dust suppression is acted on come wind or change come wind wind direction by building isolation, such as：Windbreak, closed coal bunker,
There is a certain effect to dust-proof, but cost of investment is big, easily several ten million or several hundred million.
Based on this, chemically develop a kind of coal yard wind-proof dust-suppression agent and be very important.
The content of the invention
Based on this, it is necessary to provide a kind of coal yard wind-proof dust-suppression agent.
A kind of coal yard wind-proof dust-suppression agent, is prepared from by the raw material of following parts by weight：
0.1-0.8 parts of xanthans and maltodextrin,
3-7 parts of glycerine and propane diols,
0.5-4 parts of polyvinyl alcohol,
1.5-5.5 parts of diethylene glycol,
1.5-2 parts of sodium Diacetate,
0.5-1 parts of OP-10,
100 parts of water.
In one of the embodiments, it is prepared from by the raw material of following parts by weight：
0.3-0.5 parts of xanthans and maltodextrin,
4-6 parts of glycerine and propane diols,
2-4 parts of polyvinyl alcohol,
2.5-4.5 parts of diethylene glycol,
1.7-1.9 parts of sodium Diacetate,
0.6-0.8 parts of OP-10,
100 parts of water.
In one of the embodiments, 1% solution viscosity of the xanthans is 2000-5000mPas, fineness>120
Mesh, xanthans and maltodextrin ratio are 3:1.
In one of the embodiments, described dust suppressant glycerine and propane diols ratio are 1:2.
In one of the embodiments, the degree of polymerization of described polyvinyl alcohol is 2300-2500, and preferred degree of polymerization is
2400。
The method for preparing the coal yard wind-proof dust-suppression agent, is comprised the steps of：
（1）, xanthans and maltodextrin be added to the water, the quick stirring and dissolving at 50 DEG C；
（2）, glycerine and propane diols be added to step（1）Mixture in and stir；
（3）, polyvinyl alcohol is added to the water, the stirring and dissolving at 90 DEG C adds it to step after cooling（2）It is mixed
In compound；
（4）Diethylene glycol, sodium Diacetate, OP-10 are added to step respectively（3）Mixture in, after stirring i.e.
Obtain coal yard wind-proof dust-suppression agent solution.
The principle and advantage of the present invention is as follows：
Coal-burning power plant's dump rise dirt main cause be：Dump outdoor storage, top layer coal sample is due to the effect of Exposure to Sunlight wind
Water content is extremely low, causes coal sample loose, is easy to generation airborne dust under corrosion function in wind.
Based on this principle：The present invention, as binding agent, makes dump top layer using highly viscous xanthans and maltodextrin
Coal sample one layer of duricrust of formation, there is very strong hygroscopicity can effectively be protected together with film forming agent polyvinyl alcohol for glycerine and propane diols
The moisture of top layer coal sample is held, OP-10 can improve the permeability of dust suppressant, and penetration depth of the increase dust suppressant in coal seam increases
Big crust thickness.Therefore xanthans, maltodextrin, glycerine, propane diols, several material mixings of polyvinyl alcohol are used, Ke Yiyou
The erosion for resisting to effect wind-force suppresses airborne dust.
In addition, the material that the present invention is selected has degradability, environmental pollution is not resulted in.
Further, present invention adds a certain amount of diethylene glycol, it is ensured that dust suppressant can be with -0 DEG C of low temperature -5 DEG C
Normally use.
Further, the present invention adds a certain amount of sodium Diacetate, it is ensured that dust suppressant can be preserved for a long time.
