Problems solved by technology

[0003] Atmospheric particulate matter pollution has become a prominent atmospheric environmental problem in my country in recent years, especially fine particulate matter PM 2.5 It is an important factor leading to environmental problems such as reduced atmospheric visibility, acid rain, haze weather and global climate change. The main reason is that PM 2.5 The specific surface area is large, and it is easy to enrich various heavy metals and chemical carcinogens, but it is difficult to effectively capture them by conventional dust removal technology, resulting in a large amount of PM 2.5 into the atmosphere

Embodiment 1

[0037] Take 5.2kg of homemade calcium acetate, 4.4kg of magnesium acetate, and 0.4kg of potassium acetate, add them to 50kg of water, and configure a collector solution with a concentration of 16.7% by weight. The solution is directly sprayed in the air, the solution can directly capture the particles in the air during the falling process, and after the solution falls to the ground, it can continue to capture the particles in the subsequent process. After the solution dries, particles can be continuously collected due to the easily absorbable deliquescence of the calcium magnesium acetate salt. After being washed by rainwater, the collectors and particles on the ground will enter the urban sewage pipes and will not affect the sewage treatment system.

Embodiment 2

[0040] Take 3.2kg of commercially available calcium acetate, 1.4kg of magnesium acetate, 1.5kg of calcium nitrate, 1.5kg of magnesium nitrate, and 0.4kg of potassium acetate, add water to 100kg, and configure a collector solution with a concentration of 8% by weight. Spraying the solution around the construction site can effectively control dust.

[0041]

Embodiment 3

[0043] Take 5kg of lime, 5kg of magnesium hydroxide, add 10kg of acetic acid, after the reaction is complete, add water to form a 5% solution. Spraying the solution on both sides of the road can effectively trap particulate matter.

Abstract

The invention provides an environmental-friendly atmospheric particulate trapping agent and the and application thereof in the aspect of air purification, wherein the environmental-friendly atmospheric particulate trapping agent is non-toxic, non-corrosive and harmless to the soil, and has no effect on urban sewage treatment systems. The atmospheric particulate trapping agent can be used for effectively removing particulates in the urban atmospheric environment, and improving urban local environments. The invention also provides the application of the environmental-friendly atmospheric particulate trapping agent in the aspect of air purification. The atmospheric particulate trapping agent is prepared from the following components in percentage by weight: 8-95% of calcium acetate, 8-95% of magnesium acetate, 0-60% of calcium nitrate, 0-60% of magnesium nitrate, 0-8% of potassium acetate, 0-8% of potassium nitrate, and 0-5% of diammonium hydrogen phosphate.

Description

[0001] technical field [0002] The invention belongs to the technical field of air pollution particle control, and in particular relates to an environment-friendly atmospheric particle collector, which is used to collect particles (including fine particles) in the atmospheric environment. technical background [0003] Atmospheric particulate matter pollution has become a prominent atmospheric environmental problem in my country in recent years, especially fine particulate matter PM 2.5 It is an important factor leading to environmental problems such as reduced atmospheric visibility, acid rain, haze weather and global climate change. The main reason is that PM 2.5 The specific surface area is large, and it is easy to enrich various heavy metals and chemical carcinogens, but it is difficult to effectively capture them by conventional dust removal technology, resulting in a large amount of PM 2.5 into the atmosphere. This is also the respirable particulate matter (PM) in th...
