Description

Technical Field

[0001] The utility model relates to the technical field of soil dioxin extraction, in particular to a portable soil dioxin extraction device. Background Art

[0002] Dioxins generally refer to a group of polychlorinated planar aromatic hydrocarbons with similar structures and physicochemical properties. They belong to the class of chlorinated oxygenated tricyclic aromatic hydrocarbons, including 75 polychlorinated dibenzo-1-dioxins and 135 polychlorinated dibenzofurans. They are neither artificially produced nor used for any purpose, but are byproducts of combustion and various industrial processes. Currently, the main sources of dioxins in the environment are evaporation from the use of chlorophenols for wood preservation and schistosomiasis prevention, emissions from incineration, the use of defoliants, pesticide production, paper bleaching, and automobile exhaust. Most dioxin compounds are not only carcinogenic but also have reproductive, immunotoxic, and endocrine toxicity. Among them, the 2-, 3-, 7-, and 8-chlorinated isomers (TCDD) are the most toxic. These toxic compounds can enter soil ecosystems through atmospheric dry and wet deposition, sewage irrigation, indiscriminate waste storage, and irrational agricultural use of pesticides, herbicides, and sludge. In order to control the impact of dioxins on soil ecosystems, dioxins in the soil need to be extracted. However, existing soil dioxin extraction devices are complex in structure and large in size, making them inconvenient to carry to the site, which greatly reduces the usability of the devices.
