A kind of environmentally friendly biomass dust suppressant and preparation method thereof

Abstract

The invention belongs to the technical field of dust pollution control, and discloses an environment-friendly biomass dust suppressant and a preparation method thereof. The dust suppressant is composed of carboxymethyl starch, carboxymethyl cellulose, sodium alginate, anhydrous Calcium chloride, rhamnolipids, sophorolipids and water. The dust suppressant of the present invention is low in cost, environmentally friendly, non-toxic and harmless, easy to biodegrade, has good biocompatibility with plants in the spraying area and the soil environment, and can be used in dust control work together with green plants to realize chemical dust suppression Comprehensive application with plant dust retention. When the dust suppressant solution is sprayed on the dust surface, it can form a continuous and certain-strength consolidation layer on the surface, which has good wind erosion and rain resistance performance, can withstand extreme temperature environment for a long time, and has certain moisture retention , which has a better effect of dust suppression and damage prevention.

Description

technical field [0001] The invention belongs to the technical field of dust pollution control, and in particular relates to an environment-friendly biomass dust suppressant and a preparation method thereof. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] In recent years, with the accelerated development of my country's industrialized production and urban modernization, the dust particles produced by human production and living processes such as industrial production, construction, storage and transportation of bulk materials, and exhaust emissions from motor vehicles have increased year by year. Under the action of airflow dynamics, a large amount of dust particles are suspended in the air, resulting in smog weather of varying severity across the country, which has seriously affected people's lives and health, and has aroused great concern from the society. How to take measures Cost-effective prevent...

Problems solved by technology

[0007] (1) In the prior art, the chemical dust suppressant prepared by using bio-organic polymer materials often has poor wettability, is difficult to penetrate, cannot form a surface consolidation layer with sufficient thickness and strength, and cannot fully adapt to the actual application environment Influenced by unfavorable factors such as wind and rain and prolonging the effective dust suppression cycle of dust inhibitors, the purpose of stabilizing and consolidating deposited dust and effectively avoiding secondary dust is not achieved; and the application of a single biomass material bonded into a film The performance is also relatively poor

[0008] (2) Due to the defect that chemical surfactants are not easy to biodegrade in the existing dust inhibitors, although the main material of the solution is biomass material, it may still cause secondary pollution and cause damage to the soil ecological environment in the spraying area

In order to enhance the penetration performance of dust suppressants, the method adopted by domestic and foreign researchers is mainly to add chemically synthesized surfactants to the solution to reduce the interfacial tension, enhance the wettability of the solution to dust, and realize the multifunctional compounding of dust suppressants. However, due to the defect that chemical surfactants are not easy to biodegrade, although the main material of the solution is biomass material, it may still cause secondary pollution and damage the soil ecological environment in the spraying area.
