A wind-diffused soil in-situ remediation device

Abstract

The invention discloses an air-induced diffusion type soil in-situ restoration device, which belongs to the field of soil restoration devices. An air-induced diffusion type soil in-situ restoration device includes a drip box, and the lower end of the drip box is fixedly connected with a diffusion net. The drip box is provided with a vertical hole, the upper side of the drip box is provided with a main windmill, the lower side of the drip box is provided with a fan, and the fan is located inside the diffusion net. Agitate to keep the air in a state of continuous flow, and make the auxiliary windmill and the liquid expansion floating bag rotate and float up and down under the action of the wind force with changing speed, so that the medicine dripping on the upper surface of the liquid expansion floating bag will expand with the expansion. The movement of the liquid floating bag continues to disperse to the soil around and below the diffusion net, and under the dynamic air flow, it penetrates into the soil with the continuously flowing air, thereby expanding the penetration range of the agent and improving the repair effect on the soil.

Description

technical field [0001] The invention relates to the field of soil remediation devices, and more specifically, relates to an air-induced diffusion type soil in-situ remediation device. Background technique [0002] Soil remediation is a technical measure to restore the normal function of polluted soil. In the soil remediation industry, there are more than one hundred existing soil remediation technologies, and there are more than ten commonly used technologies, which can be roughly divided into three methods: physical, chemical and biological. Among them, the chemical oxidation technology has quick results and can be used for in-situ and heterogeneous methods. In-situ remediation with controllable cost has been widely used in on-site engineering soil remediation. Chemical oxidation technology refers to the addition of oxidants to the soil to oxidize the polluted soil in the soil into low-level, easily biodegradable substances or directly degrade pollutants. Commonly used oxi...

Problems solved by technology

[0003] When chemical oxidation technology is used to repair the soil, spraying equipment is generally used to spray the agent on the soil surface, or to bury the restoration pile deeply in the soil, so that the drug solution can penetrate into the soil. Although the former method can spray a large area , but the agent is easy to accumulate on the soil surface, and a large amount of agent is easy to cause evaporation loss, and the repair effect of the deep soil is poor. In the latter method, although the agent can act on the deep layer of the soil, the position of the agent is single and it is not easy to spread. , the repair effect is also poor
