Embodiment 1
[0042] The agent spraying and ultraviolet catalysis device used for the ex-situ restoration equipment of polluted soil is mainly composed of the agent spraying device 3 and the ultraviolet catalysis device installed above the conveyor belt. The device is composed of a medicament spraying device 3 and an ultraviolet catalytic device. The device is divided into two parts, the first processing unit 1 and the second processing unit 2, according to the process flow. Wherein the first processing unit 1 has the functions of chemical spraying and ultraviolet catalysis, and the second processing unit 2 only has the function of ultraviolet catalysis. Above the discharge conveyer belt 18 of the first processing unit 1, the medicament spraying device 3 and the first ultraviolet catalytic device 4 are installed sequentially along the conveying direction, and the second ultraviolet catalytic device 5 is installed in the discharge bin 20 of the first processing unit 1; The third ultraviolet...

The invention discloses an agent spraying and ultraviolet catalytic device used for contaminated soil ex-situ remediation equipment. A first processing unit and a second processing unit are include insequence. An agent spraying device body and an ultraviolet catalytic device body are arranged in the first processing unit. An ultraviolet catalytic device body is arranged in the second processing unit. The agent spraying device body and the first ultraviolet catalytic device body in the first processing unit are sequentially installed on a discharging conveying belt. Second ultraviolet catalytic device bodies are arranged on the two sides of the soil falling face of the tail end of the discharging conveying belt. A second conveying belt is arranged below the tail end of the discharging conveying belt. The third ultraviolet catalytic device body is arranged inside the second processing unit and located above the second conveying belt. The agent spraying and ultraviolet catalytic device used for the contaminated soil ex-situ remediation equipment has the agent spraying and ultraviolet catalytic functions at the same time, and also has the advantages of being simple in structure, smallin occupied area, convenient to mount, easy to operate, safe and stable in structure and the like.
Description
technical field [0001] The invention relates to a device used on construction equipment for heterotopic restoration of polluted soil, in particular to a chemical spraying and ultraviolet catalysis device for heterotopic restoration equipment of polluted soil. Background technique [0002] In the process of traditional ex-situ remediation of contaminated soil, it is often necessary to add liquid agents to the soil, or add water after mixing the added solid agents with the soil, so as to promote the full reaction of the remediation agents and soil pollutants. In addition, studies have shown that the use of ultraviolet light to irradiate contaminated soil mixed with remediation agents can significantly promote the efficacy of some remediation agents and accelerate the degradation of target pollutants in the soil, such as cyanide in soil with the help of ultraviolet light It is easily oxidized and decomposed by oxidizing agents. [0003] Currently commonly used soil remediation...
