Abstract

The invention discloses a liquid dust coagulant, belonging to the field of coagulants. The liquid dust coagulant is synthesized from 20-30 parts by mass of acrylic, 4-6 parts by mass of sodium hydroxide, 100 parts by mass of water, acrylic acid, nano silicon dioxide, cellulose, ethylene glycol and a silane coupling agent, wherein the mass ratio of the acrylic acid to the acrylamide is 1:(1.5-2), the mass ratio of the nano silicon dioxide to the acrylamide is (5-7):(20-30), the mass ratio of the cellulose to the acrylic acid is (1-2):(5-8), and the mass ratio of the ethylene glycol to the acrylamide is (8-10):(20-30). The liquid dust coagulant can effectively coagulate fine dust in air.

Description

technical field [0001] The invention relates to the technical field of coagulants, especially fine dust coagulants. Background technique [0002] Solid particles with a diameter of 0.1-5 μm in the air have a significant impact on the quality of the air, especially particulate matter with a diameter of about 2.5 μm, namely PM2.5, which is very harmful to the air and extremely harmful to the human body . These fine dusts are difficult to remove due to their small size, large specific surface area, and the formation of relatively stable aerosols in the air. Some general physical filtration methods for larger particles cannot play a similar role in the removal of fine dust. Effect. [0003] In response to this problem, some methods with high efficiency for the removal of fine dust have adopted the idea of ​​agglomerating the fine dust first and then removing it. Contents of the invention [0004] The object of the present invention is to provide a liquid coagulant that can ...
