Problems solved by technology

[0003] At present, the countermeasures for such coal flying particles between 2.5 microns and 10 microns are spraying water or spraying water. When the temperature drops, the water will freeze after spraying, which will increase the danger to the operators; Evaporation is fast and continuous spraying is required, not only cannot completely prevent dust, but also may cause pollution

Embodiment 1

[0028] At normal temperature, in the mixing equipment, add 0.7 liters of water, then add polyvinyl alcohol 100.0g, sorbitan monooleate 10.0g and ethanol 20.0g, titanium dioxide (TiO2) 20.0g, stir for 30 minutes. Then raise the temperature to 30°C, at this temperature, slowly add 50.0g of sodium alginate dropwise, stir at 600 rpm, stir at high speed for 3 hours, and cool at room temperature to obtain a viscous white coal scatter inhibitor agent mixture.

Embodiment 2

[0030] At room temperature, add 0.7 liters of water to the mixing equipment, then add 30.0 g of dodecyl dimethyl amine oxide, 15.0 g of organosiloxane, magnesium hydroxide (MgOH) 2 15.0 g, stirred for 60 minutes. Then raise the temperature to 40°C. At this temperature, slowly drop 70.0 g of carboxymethyl cellulose, stir at 400 rpm, stir at high speed for 2.5 hours, and cool at room temperature to obtain viscous white coal. Scatter inhibitor mixture.

Embodiment 3

[0032] At room temperature, add 0.7 liter of water to the mixing equipment, then add 20.0 g of sorbitan monolauryl RATE, 10.0 g of polyether, and 8.0 g of talc (Talc), and stir for 40 minutes. Then raise the temperature to 35°C, at this temperature, slowly drop 60.0g of hydroxypropyl methylcellulose, stir at 500 rpm, stir at high speed for 2 hours, cool at room temperature, and obtain viscous White Coal Scatter Inhibitor Mixture.

Abstract

The invention relates to an inhibitor, and in particular relates to an inhibitor mixture for inhibiting coal granule flying and a preparation method of the inhibitor mixture. The coal granule flying inhibitor mixture comprises the following components in mass percent: 100% of water, 0.2%-0.8% of interfacial agent, 0.5%-3.0% of defoamer, 0.5%-3.0% of color-developing agent, 0.2%-15.0% of high molecular materials, and 0.1%-25.0% of wetting agent. According to the invention, the preparation method of the coal granule flying inhibitor mixture has the beneficial effects of being simple and easy to implement; and the coal granule flying inhibitor mixture has the beneficial effects of adopting the high molecular material which is at least one of synthetic cellulose material, hydrophilic synthetic high molecular material and natural high molecular material and is rationally blended with the interfacial agent, thus being capable of effectively absorbing superfine coal granules of 2.5-10 mu m (PM10), preventing flying of the superfine coal granules, and further, achieving the effect of making an operating environment comfortable and protecting the health of nearby residents and operators.

Description

technical field [0001] The invention relates to an inhibitor, in particular to an inhibitor mixture and a preparation method for preventing coal particles with a diameter of 2.5-10 μm (PM10) from flying during coal storage or transfer, and a preparation method thereof, belonging to the field of chemistry. Background technique [0002] During the storage or transfer of coal, particulate matter called fly ash is generated in the atmosphere. It is also emitted in places such as coal storage sites, coal crushing plants or briquette plants. This kind of coal flying particles usually floats in the air and attaches to the leaves of plants, which will have a negative impact on the growth and development of plants. It invades the human body through breathing and will accumulate in the respiratory system. Particles with a diameter of 10 microns or more will be blocked. Outside the human nose, particles with a diameter between 2.5 microns and 10 microns are usually deposited in the up...
