Abstract
The invention discloses a waterproofing binder of coal. The waterproofing binder is prepared from the following steps of mixing high molecular cellulose which is over 0.05% of total weight of the coal to be processed with water until the high molecular cellulose is completely dissolved; adding oils which are difficultly or slightly dissolved into water and are over 0.5% of total weight of the coal to be processed, and evenly stirring. The prepared waterproofing binder is added to the coal to be processed at the ratio of 5-10% of total weight of the coal to be processed. The waterproofing binder disclosed by the invention is simple in preparation method, low in material cost and production cost, and widely available to different varieties of coal.
Description
Technical field
The present invention relates to the coal processing and utilization field, especially relate to a kind of binding agent that blocks water that is applicable to each coal.
Background technology
The existing coal binding agent that blocks water mainly contains two large classes, one class is inorganic salts, such as silicate, wilkinite, aluminium dihydrogen phosphate etc., add in the coal and can increase ash, reduce the unit thermal value of coal, and be alkalescence more, use in brown coal or other low-disintegration coals can with low-disintegration coal in humic acid play untoward reaction, affect the intensity of coal and reduce fugitive constituent and the unit thermal value; Another kind of is organic, such as xylogen, Mierocrystalline cellulose, and polyvinyl alcohol or starch paste compound, this class material interpolation cost height has cohesive action but block-water effect is bad.
Summary of the invention
For the above-mentioned problems in the prior art, goal of the invention provides a kind of binding agent that blocks water of coal.This binder making method that blocks water is simple, material cost and production cost are low, generally is applicable to each coal.
The present invention solves the technical scheme that its technical problem takes:
A kind of binding agent that blocks water of coal, this binding agent that blocks water is by high molecular cellulose, and is insoluble or to be slightly soluble in oils and the water of water formulated by following weight percent; Described high molecular cellulose is more than 5/10000ths of coal gross weight to be processed, and described oils insoluble or that be slightly soluble in water is more than 5/1000ths of coal gross weight to be processed, and surplus is water.
Further, the gross weight of the described binding agent that blocks water is 5～10% of coal gross weight to be processed.
Further, the binding agent that blocks water is prepared according to the following steps: high molecular cellulose and water mix and blend with 5/10000ths above ratios of coal gross weight to be processed dissolve fully to high molecular cellulose; Add again coal gross weight to be processed 5/1000ths above ratios indissoluble or be slightly soluble in the oils of water, stirring gets final product.
Further, the viscosity unit of described high molecular cellulose is greater than 800mPa.s.
Further, high molecular cellulose and water mix and blend under 50 ℃～60 ℃ water temperature.
Compared with prior art, the invention has the beneficial effects as follows:
The binding agent that blocks water of coal of the present invention adopts insoluble or is slightly soluble in the oils of water, and this oils has viscosity, and water-repellancy is also arranged, and usually will could spread out in coal particle with a large amount of oil, reaches waterproof effect.The present invention utilizes macromolecular fibre usually to prolong molecular chain, and oil fully is diluted in a large amount of aqueous solution, does not separate not discontinue, just can evenly add a large amount of coal particle surface to a small amount of oil, can reach the effect of the bonding that blocks water with very little cost.The oils wide material sources that the present invention adopts, available petroleum products, industrial waste oil, food waste oil (sewer oil), coal tar wet goods.Especially utilize aforesaid method fully dilution of food waste oil (sewer oil), not only be easy to detect, observe its various compositions and characteristic, and making the binding agent that blocks water according to technical solution of the present invention, also is to ward off in addition an environmental protection, energy-conservation new way for the recycling of food waste oil (sewer oil).

Embodiment
A kind of binding agent that blocks water of coal, this binding agent that blocks water as coal upgrading special use is by high molecular cellulose, and is insoluble or to be slightly soluble in oils and the water of water formulated by following weight percent.Described high molecular cellulose is more than 5/10000ths of coal gross weight to be processed, and described oils insoluble or that be slightly soluble in water is more than 5/1000ths of coal gross weight to be processed, and surplus is water.The water yield that blocks water in the binding agent is added and too much can be increased coal moisture content to be processed or increase the oven dry burden.
The preparation steps of the above-mentioned binding agent that blocks water and use as follows:
One, high molecular cellulose and the water mix and blend with 5/10000ths above ratios of coal gross weight to be processed dissolves fully to high molecular cellulose.The viscosity unit of described high molecular cellulose should be greater than 800mPa.s.High molecular cellulose and water are preferably in that mix and blend dissolves fully to Mierocrystalline cellulose under 50 ℃～60 ℃ the water temperature.Described high molecular cellulose consumption gets final product greater than 5/10000ths of coal gross weight to be processed, and consumption is larger, and bond effect is better, but cost is higher.
Two, add again coal gross weight to be processed 5/1000ths above ratios indissoluble or be slightly soluble in the oils of water, stirring gets final product.Described indissoluble or be slightly soluble in the oils wide material sources of water, available petroleum products, industrial waste oil, food waste oil (sewer oil), coal tar wet goods.Indissoluble or the oils addition that is slightly soluble in water are just producing effect more than 5/1000ths of coal gross weight to be processed, and addition is larger, and effect is better, but cost raises.
Three, the above-mentioned binding agent that blocks water that makes is sprayed at equably coal to be processed surface, or mixes afterwards with coal to be processed and fully to stir with stirrer.For powdery coal to be processed, but die mould after the stirring, but granulation also can be dried cold conditions or hot all can gaining in strength and waterproof effect.The described binding agent that blocks water is that 5～10% ratios take its gross weight as coal gross weight to be processed are added in the coal to be processed.
