Device and method for trapping and removing mercury in atmosphere

[0040] Example 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 cylindrical collection tube 4 An aluminum pleat trapping device 3 is arranged at the upper port of the hood; the cylindrical collecting cylinder 4 is fixed in the base 5 with the aluminum pleat trapping device 3 , and the bottom of the base 5 is connected to a fixed cone 6 .

[0043] The height of the entire device is controlled to be 60cm, the diameter of the tile-type rain-proof, sun-proof and breathable top cover 1 is set to 60cm, and the tile-type rain-proof, sun-proof and breathable top cover 1 is made of stacked light-weight tiles that are impermeable to water and light. For example, the mushroom cap is designed to have a high center and a low surrounding structure. The tiles are vertically pressed up and down in a scale-like manner. They are stacked on top of each other. There are certain ventilation holes A11 in the horizontal direction to facilitate the lowering of the top cover. The air after the mercury is removed through the aluminum pleats can diffuse through the ventilation holes A11, which is more conducive to the surrounding air entering the aluminum pleated structure to complete the generation of amalgam. The aluminum pleated trapping is designed under the tile-type rainproof, sunscreen and breathable top cover 1. Device 3, the diameter of the aluminum pleat trapping device 3 is 50cm, and the aluminum pleat trapping device 3 is made of thin aluminum sheet, shaped like the fungus gills at the bottom of the mushroom fruiting body, the aluminum pleats can be replaced, and the raised part of the aluminum pleats is designed There is a ventilation hole B31 corresponding to the ventilation hole A11, and a concave part 32 for the amalgam to flow is formed on the aluminum pleat trapping device 3 between the adjacent protrusions to ensure the normal circulation of air in the device and the mercury in the atmosphere. After contacting with the aluminum pleats, a viscous (liquid) amalgam is generated, and the amalgam appears to flow into the cylindrical collecting cylinder 4 along the inner recess 32 of the aluminum pleating. The cylindrical collecting cylinder 4 is made of iron, which is the material with the worst solubility in mercury It is formed and can be replaced, and is used to collect the amalgam collected on the aluminum pleated trapping device 3; the top cover support column 2 is used to support the tile-type rainproof, sunscreen and breathable top cover 1, and the base 5 is set on the ground for connecting the columnar The collection tube 4 is used to fix the entire device. At the same time, the fixed cone 6 is inserted into the soil to fix the overall device. The tile-type rain-proof, sun-proof and breathable top cover 1 and the base 5 are designed to have a deep heat-absorbing color. Colors, such as black or dark green, use solar radiation to heat the atmosphere near the ground, speed up the air circulation in the device, and increase the air exchange rate inside the device. The rate of amalgam formation.

[0044] Example 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 through distillation operation, thereby realizing the removal of mercury from the atmospheric environment, and having the potential for resource utilization of mercury elements .

[0049] The above-mentioned device is mainly used to collect mercury that falls into the soil through dry or wet deposition and is released into the air for the second time, or gaseous mercury released in large quantities in areas with high mercury content in the soil. The generated amalgam is fed into the collection device to complete the collection. The cylindrical collection cylinder 4 is made of iron, which is the material with the worst solubility in mercury, which can prevent the cylindrical collection cylinder 4 from being lost due to the generation of amalgam. The amalgam collected by the collecting device can be recovered in a centralized manner, and then the separation of mercury and other metals can be realized through distillation operation, thereby realizing the removal of mercury from the atmospheric environment, and has the potential of resource utilization of mercury element.
