Problems solved by technology

[0004] During the transportation and storage of coal, a large amount of dust will be generated. The dust not only brings serious pollution to the environment, but also causes the loss of coal in the process of transportation and storage.

preparation example Construction

[0029] The present invention also provides a kind of preparation method of coal moisture-retaining and dust-suppressing agent, comprises the steps:

[0030] A. Mix 400-600 parts by weight of water and 1-3 parts by weight of alginic acid, and stir evenly to obtain liquid A;

[0031] B. Mix 400-600 parts by weight of water with 2-4 parts by weight of calcium lactate and stir evenly to obtain liquid B;

[0032] C. Mix 0.5-1.5 parts by weight of dispersant with 400-600 parts by weight of soybean oil and 50-150 parts by weight of glycerin, and stir evenly to obtain liquid C; preferably, the dispersant is T154 or dodecane Sodium phenyl sulfonate;

[0033] D. Mix the liquid C with the liquid B, stir evenly, then add the liquid A, and stir with a homogenizer for 1 to 2 hours after mixing to obtain a coal moisturizing and dust suppressing agent.

[0034] Since the moisturizing and dust suppressant needs to form a water-in-oil emulsion to function, it needs to be divided into liquids ...

Embodiment 1

[0041] A. Mix 5 tons of water and 20 kg of alginic acid evenly to obtain liquid A, and stir 5 tons of water and 30 kg of calcium lactate evenly to obtain liquid B;

[0042] B. Mix 10 kilograms of dispersant T154 with 5 tons of reclaimed bio-oil and 1 ton of glycerin to obtain liquid C;

[0043] C. Mix liquid C and liquid B, then add liquid A, after mixing, stir with a homogenizer for 1 to 2 hours to obtain a coal moisturizing and dust suppressing agent.

[0044] By adding the coal moisturizing and dust suppression agent in this example during transportation, under the same cargo compartment volume, the proportion of upgraded coal without adding dust suppressant is increased, reducing the loss of upgraded coal during transportation. Ton phenomenon and road loss.

Embodiment 2

[0046] A. Mix 4 tons of water and 10 kg of alginic acid evenly to obtain liquid A, and in addition, stir 4 tons of water and 20 kg of calcium lactate evenly to obtain liquid B;

[0047] B. Mix 5 kg of dispersant T154 with 4 tons of reclaimed bio-oil and 0.5 tons of glycerin to obtain liquid C;

[0048] C. Mix liquid C and liquid B, then add liquid A, after mixing, stir with a homogenizer for 1 to 2 hours to obtain a coal moisturizing and dust suppressing agent.

[0049] By adding the coal moisturizing and dust suppression agent in this example during transportation, under the same cargo compartment volume, the proportion of upgraded coal without adding dust suppressant is increased, reducing the loss of upgraded coal during transportation. Ton phenomenon and road loss.

Abstract

The invention relates to a moisture-retention dust suppression agent for coal and a preparation method of the moisture-retention dust suppression agent. The moisture-retention dust suppression agent comprises 800-1200 parts by weight of water, 1-3 parts by weight of alginic acid, 2-4 parts by weight of calcium lactate, 0.5-1.5 parts by weight of a dispersant, 400-600 parts by weight of soybean oiland 50-150 parts by weight of glycerol. The dust suppression agent for moisture retention of coal is water-in-oil emulsion; after the emulsion is sprayed, the effective components in the emulsion areadsorbed and complexed with pulverized coal, and fine pulverized coal prone to dust raising is bonded and agglomerated into non-raised dust particles with larger particle size, so that the content offine powder in upgraded coal is reduced, and the purpose of dust suppression is fundamentally achieved. By adding the moisture-retention dust suppression agent for coal in the transportation process,specific gravity is increased as compared with upgraded coal without the dust suppression agent under the condition of the same cargo compartment volume, so that the shortfall and road loss of upgraded coal in the transportation process are effectively reduced, and economic benefits of coal enterprises are increased.

Description

technical field [0001] The invention relates to a dust suppressant and a preparation method thereof, in particular to a preparation method of a coal moisturizing dust suppressant. Background technique [0002] Dust pollution has become the largest source of pollution in the world's public hazard pollution. In recent years, the vigorous development of the mining industry, the increase of the coal transportation industry, the construction of urban infrastructure, and the accumulation of garbage and waste have all made dust pollution more and more serious, especially PM10 and PM2.5, which have a large contribution to dust pollution, have attracted much attention . [0003] With the advancement of science and technology and the continuous improvement of people's living standards, how to reduce dust pollution has attracted great attention. At present, the commonly used methods of dust reduction include dust suppressants, wet dust control, setting up windbreak forest and windproo...
