Abstract
Description
Technical Field
[0001] This utility model relates to the field of soil remediation technology, and in particular to a deep injection device for soil remediation agents. Background Technology
[0002] Soil pollution has become a major issue in global environmental governance, especially the accumulation of pollutants such as heavy metals and organic matter in soil, which poses a serious threat to ecosystems and human health. Currently, soil remediation technologies mainly fall into three categories: physical remediation, chemical remediation, and bioremediation. Among these, chemical remediation is widely used due to its rapid and efficient characteristics, and chemical injection technology, as one of the important methods of chemical remediation, can directly deliver remediation agents to deeper areas of contaminated soil, thereby achieving targeted remediation. However, existing technologies still have many limitations in practical applications, such as uneven agent distribution and difficulty in controlling injection depth, which affect the remediation effect and efficiency.
[0003] A search revealed Chinese Patent Publication No. CN220259076U, which discloses a nutrient solution injection device for soil remediation. The device includes a bottom insert and a pressing rod. The bottom insert has a pressurizing chamber. This nutrient solution injection device injects chemical nutrient remediation solution directly from below the ground by inserting the bottom insert below the surface, ensuring effective contact between the deep soil and the chemical nutrient remediation solution. This allows for direct remediation of deep soil, improving the overall soil remediation effect. Rotating the pedal adjusts the maximum insertion depth of the bottom insert into the soil, thereby adjusting the depth to which the nozzle sprays the chemical nutrient remediation solution into the soil. This allows for remediation of soil at different depths and pollution levels, improving targeting and enabling the use of different chemical agents for different levels of pollution and pollutants, thus enhancing the soil remediation effect and applicability. However, the above structure is not effective enough for injecting into harder soils, as it cannot evenly inject the agent into the deeper soil layers. Utility Model Content
