Embodiment 1

[0041] see Figure 1-5 , Figure 5 The direction of the arrow in the figure is the direction of airflow movement. The air near the ground rises after heating and enters the interior of the device through the pores of the aluminum pleated trapping device 3 to achieve mercury capture. The pores on the cover 1 then continue to move upward, so that the purified air can escape into the atmosphere.

[0042] In the embodiment of the present invention, a device for capturing and removing mercury in the atmosphere is provided, including a tile-type rainproof, sun-proof and breathable top cover 1 , a top cover support column 2 , an aluminum pleated trapping device 3 , a cylindrical collection cylinder 4 , and a base 5 and fixed cone 6; one end of the top cover support column 2 is fixedly connected to the center of the tile-type rainproof, sunscreen and breathable top cover 1, and the other end of the top cover support column 2 is fixed in the cylindrical collection tube 4; the cylindrica...

Embodiment 2

[0045] Based on the device provided in the above-mentioned Embodiment 1, this embodiment further provides a method for using the device, which includes the following steps:

[0046] The first step: after assembling the above-mentioned trapping and removing device, fix the whole device on the soil surface passing through the dry or wet sedimentation area through the fixing cone 6;

[0047] Step 2: Mercury in the soil that is released into the air or gaseous mercury released in a large amount in the high mercury content area of ​​the soil enters the device through the ventilation holes B31 on the surface of the aluminum pleats on the aluminum pleat trapping device 3 and contacts the aluminum pleats to generate The amalgam is merged into the cylindrical collection tube 4 to complete the collection;

[0048] The third step: the collected amalgam can be recovered centrally in the cylindrical collection cylinder 4, and then the separation of mercury and other metals can be realized ...

Abstract

The invention discloses a trapping and removing device and method for mercury in the atmosphere. The trapping and removing device comprises a tile-type rainproof and sunscreen breathable top cover, a top cover supporting column, an aluminum fold trapping device, a cylindrical collecting barrel, a base and a fixing cone. One end of the top cover supporting column is fixedly connected to the center of the tile-type rainproof and sunscreen breathable top cover, and the other end of the top cover supporting column is fixed in the cylindrical collecting barrel; an aluminum pleat trapping device is arranged at the upper end opening of the cylindrical collecting barrel; the cylindrical collecting barrel and the aluminum fold trapping device are fixed in the base, and the bottom of the base is connected with the fixing cone. The principle that mercury and aluminum in the atmosphere can generate aluminum amalgam is used for capturing mercury in the atmosphere, then the effects of reducing the content of mercury in the atmosphere and improving the current situation of mercury pollution in the atmosphere are achieved, the whole device can be directly used for collecting gaseous mercury released by a non-point source, detailed design can also be conducted, and the cost is reduced. And the whole structure can be integrated with a place where the device is placed, so that the device has an ornamental value and harmoniously coexists with the surrounding environment.

Description

technical field [0001] The invention relates to the technical fields of environmental science and ecological restoration, in particular to a device and method for capturing and removing mercury in the atmosphere. Background technique [0002] As we all know, mercury is one of the most toxic heavy metal pollutants, and has been listed as a priority pollutant by my country and the United Nations Environment Program, the World Health Organization, the European Union and the United States Environmental Protection Agency. [0003] The severity and complexity of mercury pollution far exceeds that of conventional pollutants. Mercury can cause damage to human health in a small dose. The toxicity of mercury and its compounds will vary depending on the method of inhalation or ingestion, or the amount. . The damage to the human body is mostly chronic neurotoxicity, and acute poisoning is a minority. The most dangerous mercury organic compound is dimethyl mercury [(CH 3 ) 2 Hg], onl...
