Problems solved by technology

However, no matter what kind of dust particles, due to their hydrophobic nature and the high surface tension of water, when the dust encounters water mist or water curtain, it cannot be quickly wetted and agglomerated by water. Water mist dust reduction is only through collision, interception, etc., to promote dust to fall, resulting in limited dust reduction effect

Abstract

The present invention discloses a dust inhibitor and a preparation method thereof, wherein the dust inhibitor comprises the following raw materials by mass: 0.001-4.50% of a surfactant, 0.001-4.00% of an alcohol auxiliary agent, 0.005-3.00% of an inorganic salt additive, and the balance of water, wherein the alcohol auxiliary agent is at least one selected from ethanol, ethylene glycol, glycerol, n-butanol and polyethylene glycol. According to the present invention, the dust inhibitor is mainly used in the wet spraying dust falling process and can be rapidly dispersed in water; during the use, the dust inhibitor is added to water for spraying dust falling, rapid wetting and flocculation agglomeration are performed on the dust produced during mining, blasting construction and other production processes along with the mist droplet spraying so as to promote the dust to rapidly fall and improve the spraying dust falling efficiency; and the dust inhibitor can further be added to the dust inhibition bag or water flooding so as to improve the blasting dust falling efficiency or water flooding dust falling efficiency.

Description

technical field [0001] The invention belongs to the technical field of mine environmental protection and mine safety production, and specifically relates to a dust suppressant for spraying dust suppression, dust suppression during blasting construction, water injection and other wet spray dust suppression and a preparation method thereof. Background technique [0002] Dust is fine particles produced during mine mining, storage, loading, transportation and stockpiling, which can be suspended in the atmosphere for a long time, causing the visibility of the surrounding atmosphere to decrease, causing operators to suffer from pneumoconiosis, and may lead to safety production accidents. According to statistics, coal mining, excavation, and storage, loading, and transportation operations may produce dust. Among them, mining operation dust production accounts for about 40% to 80% of the total dust, tunneling operation dust production accounts for about 20% to 40% of the total dust ...
