Problems solved by technology

During the transportation of the railway, due to the bumps caused by the roadbed, turnouts and track facilities, coupled with the action of wind, the mineral powder on the surface of the mineral in the train is scattered on the ground, resulting in dust pollution; in the tunnel, the concentration of mineral powder can even reach an alarming level. level of suffocation, extreme reduction in visibility
This not only caused economic losses to relevant enterprises and units, but also caused serious pollution to the environment along the way, and seriously affected the production and life of surrounding residents.
The current solution is tarpaulin covering, but this method is not only time-consuming and labor-intensive, but also has poor effect

[0019] In yet another aspect, the present invention also provides a method for preparing the dust suppressant in use, wherein the method comprises: polyacrylamide, polyvinyl alcohol, guar gum, sodium carboxymethyl cellulose, dodecyl Sodium alkyl sulfate and sodium carboxymethyl starch are mixed with water in turn.

[0020] In another aspect, the present invention also provides a method for suppressing dust from iron ore transportation, wherein the method includes: spraying the dust suppressant in use on the accumulation surface of iron ore.

[0021] Wherein, relative to each square meter of iron ore accumulation surface, the spraying amount of the dust suppressant may be 1.5-3 liters.

[0022] Wherein, the particle size of the iron ore is 0.25-10 mm; the dust suppressant and method of the present invention are particularly suitable for suppressing the transportation dust of the iron ore with a particle size of 0.25-10 mm.

Embodiment 1

[0025] The polyacrylamide of 1 weight part, the polyvinyl alcohol of 1.65 weight parts, the guar gum of 1.9 weight parts, the sodium carboxymethyl cellulose of 2.3 weight parts, the sodium lauryl sulfate of 0.9 weight part and 3.2 weight parts successively The sodium carboxymethyl starch of 1,000,000,000,000,000,000,000,000, and is mixed homogeneously with water, obtains colloidal solution, and the consumption of water makes relative to the water of 100 weight portions, and the content of polyacrylamide is 0.25 weight portion. The colloidal solution obtained in this example is the dust suppressant in use.

Embodiment 2

[0027] The polyacrylamide of 1 weight part, the polyvinyl alcohol of 1.4 weight parts, the guar gum of 2.1 weight parts, the sodium carboxymethyl cellulose of 2.1 weight parts, the sodium lauryl sulfate of 1.1 weight parts and 3.0 weight parts successively The sodium carboxymethyl starch of 1,000,000,000,000,000,000,000,000, and is mixed homogeneously with water, obtains colloidal solution, and the consumption of water makes relative to the water of 100 weight portions, and the content of polyacrylamide is 0.25 weight portion. The colloidal solution obtained in this example is the dust suppressant in use.

Abstract

The invention discloses a dust suppressant, a use of the dust suppressant, a preparation method of the dust suppressant and a method for suppressing dust during transportation of ironstone. The dust suppressant disclosed by the invention contains polyacrylamide, polyvinyl alcohol, guar gum, sodium carboxymethyl cellulose, sodium dodecyl sulfate and sodium carboxylmethyl starch. The dust suppressant disclosed by the invention can significantly suppress the dust in the particle size of 0.25-10mm during the transportation of the ironstone.

Description

technical field [0001] The invention relates to the field of chemical engineering, in particular to a dust suppressant, the use of the dust suppressant, a preparation method of the dust suppressant, and a method for suppressing dust from iron ore transportation. Background technique [0002] Iron ore is an important raw material for iron and steel production enterprises, and the railway transportation of iron ore powder is necessary to ensure the harmonious and stable development of iron and steel enterprises across the country. During the transportation of the railway, due to the bumps caused by the roadbed, turnouts and track facilities, coupled with the action of wind, the mineral powder on the surface of the mineral in the train is scattered on the ground, resulting in dust pollution; in the tunnel, the concentration of mineral powder can even reach an alarming level. The degree of suffocation, the visibility is extremely reduced. This not only caused economic losses to...
