A kind of coal moisturizing dust suppressant and preparation method thereof

Abstract

The invention relates to a coal moisturizing and dust suppressing agent and a preparation method thereof, comprising 800-1200 parts by weight of water, 1-3 parts by weight of alginic acid, 2-4 parts by weight of calcium lactate, and 0.5-1.5 parts by weight of a dispersant , 400-600 parts by weight of soybean oil and 50-150 parts by weight of glycerin. The coal moisturizing and dust suppression agent provided by the present invention is a water-in-oil emulsion. After the above emulsion is sprayed, the active ingredients in it will be adsorbed and complexed with the coal powder, and the fine and dusty coal powder will be bonded and agglomerated into The non-dusting particles with large particle size reduce the content of fine powder in the upgraded coal and fundamentally achieve the purpose of dust suppression. By adding coal moisturizing and dust suppressant during transportation, under the same cargo compartment volume, the proportion of upgraded coal without adding dust suppressant is increased, thus effectively reducing the loss of tons of upgraded coal during transportation and road loss, increasing the economic benefits of coal enterprises.

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...

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.
