Problems solved by technology

[0003] Haze pollution is not a natural phenomenon. When the horizontal wind weakens, it is not conducive to the expansion and dilution of local pollutants to the periphery, and it is easy to accumulate high-concentration pollution
Coupled with the phenomenon of temperature inversion layer, pollutants cannot convect to high altitude, thus forming large-scale haze

Embodiment 1

[0030] Example 1: The following preparation composition is used for large-scale operation of quartz sand in shale oil and gas production well sites. Quartz sand is the most widely used proppant in shale oil and gas hydraulic fracturing, and the consumption of each well is about 1,000 tons. The dust generated by the resulting large amount of quartz sand in the process of static stacking and dynamic transmission at the well site needs to be effectively controlled to protect the on-site construction personnel and the environment from harm.

[0037] Preparation composition

[0038] Spray the above-mentioned foggy water system preparation to a road surface with a length of 8 meters and a width of 3 meters with a common sprayer. In the dose range of 1.0-1.5 liters / square meter, the target plot can be effectively moistened and maintained in a moist state for more than 28 days. During the day, the highest temperature reaches 34°C, and the lowest nighttime temperature is 3.2°C. During the monitoring process, the field did not produce any dust visually, and the cumulative weight of dust collected was 35 grams. And the weight of dust collected per square meter of the surrounding untreated land exceeds 200 grams per day.

[0042] Spray the above-mentioned foggy water system preparation to a road surface with a length of 8 meters and a width of 3 meters with a common sprayer. In the dose range of 1.0-1.5 liters / square meter, the target plot can be effectively moistened and maintained in a moist state for more than 28 days. During the day, the highest temperature reaches 34°C, and the lowest nighttime temperature is 3.2°C. During the monitoring process, the field did not produce any dust visually, and the cumulative weight of dust collected was 19 grams. And the weight of dust collected per square meter of the surrounding untreated land exceeds 200 grams per day.

Abstract

The invention relates to a material and a method used for dust removal and dust prevention in air. Effective components include maltose, sodium lignosulphonate, corn hemicelluloses, sodium alginate, guar gum, glycerinum, rosin resin, calcium chloride and urea. The material can effectively adsorb the dust to result in aggregation and settlement, and a proper dosage of material is used for processing a solid surface on which dust tends to raise or air in regions with formed haze or other dust or aerosol pollution by adopting an atomizing manner. According to the invention, the technical scheme of taking the material with nano micro viscosity as the basis can be used initiatively, and small dust particles can be captured in different ranges, so that the dust can settle through agglomeration; dust of 10 microns, 2.5 microns and below in air can be effectively removed, so that the danger to human health caused by fine particulates can be alleviated.

Description

technical field [0001] The invention relates to materials and methods for dust removal and dust prevention in the air. The invention uses environment-friendly renewable materials to form a water system preparation and does not cause secondary pollution to the environment. Background technique [0002] Haze is an air pollution phenomenon formed by solid particles. Its core is the suspended particle dust in the air in the form of aerosol, which contains hundreds of chemical substances, such as sulfide, nitrate, organic matter, and tiny dust particles, smoke particles or salt particles. They can easily invade the human respiratory tract and lung lobes, and long-term exposure can cause diseases such as the respiratory system, cardiovascular system, blood system, reproductive system, etc., especially harmful to the elderly and infants. For every 10 micrograms / m increase in PM2.5 concentration 3 , the incidence of lung cancer will increase by 33%. [0003] Haze pollution is not...
