Ecological environment-friendly dust inhibitor

Abstract

The invention provides an ecological environment-friendly dust inhibitor which comprises the following components by weight percent: 0.5-0.8% of modified starch, 0.05-0.10% of microbial polysaccharide, 0.1-0.3% of cellulose derivative, 0.05-0.10% of netty accelerant, 0.05-0.15% of flow dispersant, 0.01-0.10% of film forming agent and 98.0-99.0% of water. The dust inhibitor can enable coal or mineral powder to form a layer of curing film on the surface, is high in viscosity and low in wind erosion rate, can avoid the flowing dust pollution and the flowing dust loss of the coal or the mineral powder to the way side in the railway transportation process, and has a huge economic benefit and a social benefit of environmental protection for railway transportation and coal or mineral powder customers; and the components and a solution of the dust inhibitor do not have any toxic side effect and corrosive effect, the dust inhibitor does not cause any secondary pollution as the dust inhibitor can be quickly and biochemically degraded in the nature after the dust inhibition action period, and the soil can be properly improved.

Description

technical field [0001] The invention relates to the technical field of dust suppression, in particular to an eco-friendly dust suppressant, which is used for dust suppression in railway coal and mineral powder transportation, and can also be widely used in the suppression of dust in mine roads, urban roads, construction sites, station wharves and the like. Background technique [0002] China's railway coal and mineral powder transportation is generally transported by gondola cars. Due to the bumps caused by roadbeds, turnouts and rail facilities, coupled with wind force, fine powder particles with a fineness of less than 30-40 mesh standard sieves are blown away from the car body and fall. On the road, after being rolled by subsequent vehicles, secondary dust with smaller particle size and higher concentration will be formed, resulting in the loss of coal and mineral powder and pollution along the road. [0003] First, it will cause serious pollution to the environment along...

AI Technical Summary

Problems solved by technology

[0002] China's railway coal and mineral powder transportation is generally transported by gondola cars. Due to the bumps caused by roadbeds, turnouts and rail facilities, coupled with wind force, fine powder particles with a fineness of less than 30-40 mesh standard sieves are blown away from the car body and fall. After reaching the road surface, after being rolled by subsequent vehicles, secondary dust with smaller particle size and higher concentration will be formed, resulting in the loss of coal and mineral powder and pollution along the road

[0003] First, it will cause serious pollution to the environment along the line. The dust scattered along the line will generate secondary dust when the subsequent trains pass by, forming a pollution belt, which will affect the normal growth of crops and trees in the farmland within 30-80m on both sides of the railway. And it also produces serious pollution to the body of other vehicles passing by.

[0004] Second, it poses a threat to driving safety. When the train passes through the tunnel, even if the height of the loaded goods is 100-150mm lower than the compartment, powder particles with a diameter of 30-50mm can be blown out of the train.

The thickness of coal powder and mineral powder increases at a rate of about 200-300mm per month at the entrance of the tunnel. The concentration of coal dust in the tunnel is suffocating, and the visibility is less than 10-20m. The locomotive heat dissipation network is installed, which increases the working environment temperature of the electrical equipment in the locomotive, often causing equipment failure and seriously threatening the operation safety of the train

[0005] Third, it has a great impact on the equipment along the line. The dust has seriously polluted the track bed of the railway line, aggravating the degree of compaction. In the heavily polluted section, the dust has buried fasteners, sleeper boards and other parts, causing daily labor for the engineering department. Maintenance and repairs bring considerable difficulties, serious corrosion of rails and fasteners, causing safety hazards
