Problems solved by technology

[0003] At present, there is no very mature experience at home and abroad that can be used for reference. At present, some are covered with tarpaulin, and most of the measures are to spray water mist to reduce dust, which wastes water resources, and the effect is limited; It will reduce the low-level heat generation
There are also some that use covering agents. For example, a technology in Japan is to use polyacrylate and starch graft copolymer to fuse and spray on the surface of coal, but the amount of spraying is one kilogram per square meter, which is very expensive and unfavorable. heavily used and promoted

Embodiment 1

[0021] A kind of coal pile dustproof agent, the weight percent of its each component is formed as:

[0022]

[0023] The coal pile dustproof agent is prepared by the following method: according to 100 parts by weight, 72.5 parts of reverse osmosis pure water, 10 parts of modified starch, 15 parts of sodium carboxymethyl cellulose, 2 parts of isomeric alcohol polyoxyethylene ether, 0.5 part of isothiazolinone, after stirring for 5 minutes, use mobile spraying equipment to evenly spray on the surface of the coal pile according to the amount of 100 grams per square meter of stock solution.

[0024] According to on-site testing, under the condition of wind speed of 15 meters per second, the concentration of coal ash dust is reduced to less than 0.3 mg per cubic meter.

Embodiment 2

[0026] A kind of coal pile dustproof agent, the weight percent of its each component is formed as:

[0027]

[0028] The coal pile dustproof agent is prepared by the following method: 100 parts by weight, 89.9 parts of reverse osmosis pure water, 4 parts of modified starch, 5 parts of sodium carboxymethylcellulose, 1 part of isomeric alcohol polyoxyethylene ether, 0.1 part of isothiazolinone, after stirring for 3 minutes, use mobile spraying equipment to evenly spray on the surface of the coal pile according to the amount of 160 grams per square meter of stock solution.

[0029] According to on-site testing, under the condition of wind speed of 15 meters per second, the concentration of coal ash dust is reduced to less than 0.3 mg per cubic meter.

Embodiment 3

[0031] A kind of coal pile dustproof agent, the weight percent of its each component is formed as:

[0032]

[0033] The coal-heap dustproof agent is prepared by the following method: according to 100 parts by weight, 77.2 parts of reverse osmosis pure water, 8 parts of modified starch, 13 parts of sodium carboxymethylcellulose, 1.5 parts of isomeric alcohol polyoxyethylene ether, 0.3 parts of isothiazolinone, after stirring for 4 minutes, use mobile spraying equipment to evenly spray on the surface of the coal pile according to the amount of 130 grams per square meter of stock solution.

[0034] According to on-site testing, under the condition of wind speed of 15 meters per second, the concentration of coal ash dust is reduced to less than 0.3 mg per cubic meter.

Abstract

The invention discloses a coal pile dustproofing agent. The coal pile dustproofing agent has a composition shown in the description in the weight percentage ratio. The coal pile dustproofing agent isuniformly sprayed to the surface of a coal pile through a mobile spray device according to a ratio of 90-180g / m<2>. The coal pile dustproofing agent has strong adhesiveness, can well seal the coal seam, can prevent dust scattering, realizes a low cost, does not adversely affect the combustion of coal, prevents pollution caused by combustion and can be used for storage and transportation of variouscoal piles.

Description

technical field [0001] The invention relates to a dustproof agent, in particular to a coal pile dustproof agent. Background technique [0002] With the development of science and technology and the progress of human beings, electricity has increasingly become an indispensable resource for people. Many of the current power plants still need to rely on a large amount of coal resources, which requires a large amount of coal mining, storage and transportation. Usually, most of the coal piles in power plants and mines are stored in open spaces. Under the action of wind, the dust on the surface is flying, which affects the on-site operation environment and the surrounding environment. Moreover, the transportation of coal mainly relies on railways. Since coal transportation patents are generally not closed, when the vehicles are driving, the coal powder on the surface of the coal seam will be blown up due to the action of the wind, which will pollute the buildings and farmland alo...
