Novel material capable of quickly settling suspended particulates

Abstract

The invention discloses a novel material capable of quickly settling suspended particulates. The novel material capable of quickly settling suspended particulates comprises a wetting agent, a foaming agent, a coating agent, an adhesive, a settling agent and a dispersing agent. The wetting agent is EO-PO polylol; the foaming agent is sodium N-lauroyl sarcosinate; the coating agent is carboxymethyl chitosan; the adhesive is water glass; the settling agent is aluminum potassium sulfate dodecahydrate; and the dispersing agent is a water-ethanol mixture. The wetting agent can wet suspended particulates with different compositions and particle sizes, and adjust the surface tension. The foaming agent can increase the collision capture probability between the material and suspended particulates. The coating agent can be coated on the suspended particulates to firmly capture the suspended particulates, thereby avoiding secondary pollution. The adhesive can enhance the bonding strength between the suspended particulates and the material disclosed by the invention. The settling accelerant can aggregate the coated and bonded suspended particulates, thereby accelerating settling. The removal effect of suspended particulates is greatly enhanced by using the principles of wetting, foaming, coating, bonding and settling acceleration.

Description

technical field [0001] The invention belongs to the field of atmospheric environment treatment, and in particular relates to a new material capable of rapidly settling suspended particles. Background technique [0002] Suspended particulate matter is not a single-component pollutant, but a mixture of a large number of complex chemical substances emitted by various man-made and natural sources, and is characterized by particle size, shape, chemical composition, and temporal and spatial distribution. , sources, atmospheric processes, and lifetimes all vary greatly. At present, the aerodynamic diameter of suspended particulate matter studied in atmospheric environmental science is usually between 0.1 and 100 μm. The particle size of suspended particulate matter is an important index to describe particulate matter. Suspended particulate matter in the air is usually divided into total suspended particulate matter (TSP, refers to particles with an aerodynamic equivalent diameter...

AI Technical Summary

Problems solved by technology

[0004] At present, the common treatment methods for atmospheric suspended particulates include filter material filtration and high-voltage electrostatic water spraying. The former can only be used indoors or in a small area because of the need for frequent replacement of filter materials and high cost of use. The latter is due to low treatment efficiency. , and cannot fundamentally deal with the problems of suspended particles, so it is urgent to develop a new material that can quickly settle suspended particles, which can not only quickly and firmly capture suspended particles, but also eradicate suspended particles without secondary pollution
