Problems solved by technology

However, the general wet spray dedusting technology uses ordinary water, which can only have dust reduction effect on dust and larger hydrophilic particles, and the total dust reduction efficiency is only 50% to 60%. Among them, the dust reduction efficiency on PM2.5 Even lower, only 20% to 30%, has almost no effect on hydrophobic PM2.5, seriously affecting the effect of spray dust reduction
[0005] Patent CN104307275A proposes an air purification device using activated water and its air purification device. The activation device is used to treat water into activated water to achieve the effect of purifying the air. The activated water only uses the activation device to change the water molecular structure, which can only achieve partial Dust reduction effect cannot effectively capture and settle PM2.5 positively charged colloidal particles, especially hydrophobic PM2.5, so how to improve the capture efficiency of PM2.5 is of great significance for the control of urban PM2.5 pollution

Abstract

The invention discloses a negatively charged activated water for enhancing the adsorption of PM2.5 particles, which is composed of the following components in weight percent: 97% to 99% of water, 0.1% to 1% of anion (non)ionic surfactant, and 0.1% of diffusing agent %~1%, emulsifier 0.1%~0.5%, fungicide 0.1%~0.5%. The invention also discloses a preparation method of the negatively charged activated water with enhanced adsorption of PM2.5 particles. The activated water in the present invention has excellent performance, small water molecules and negative charge, high infiltration and adsorption, low cost to the air, easy operation, environmental protection, no pollution, and can effectively capture PM2.5 in the air, including Hydrophobic particles.

Description

technical field [0001] The invention relates to activated water and a preparation method thereof, in particular to a negatively charged activated water with enhanced adsorption of PM2.5 particles and a preparation method thereof. Background technique [0002] With the rapid development of industrialization and urbanization, along with the extensive use of fossil fuels in various industrial processes, residents' living processes and the operation of various means of transportation, the harmful gases emitted into the air have increased greatly, and the PM2.5 in the atmospheric environment has been greatly increased. content increased sharply. [0003] According to statistics, the composition of PM2.5 is very complex, including hundreds of atmospheric particles, of which mineral aerosols account for about 35%, sulfate and organic carbon aerosols account for about 30%, nitrates account for about 7%, and ammonium salts account for about 30%. The proportion is about 5%, and the c...
