Abstract

Stirring equipment capable of realizing online near infrared spectrum monitoring of soil stabilizing process comprises a stirring device and a near infrared detection system. The stirring device comprises a stirring box, the top of the stirring box is provided with a soil feeding port, an agent feeding port and a monitoring port, a first spiral stirrer and a second spiral stirrer are arranged in the stirring box, the near infrared detection system comprises a near infrared detector, a cover made of quartz, an agent nozzle and a processor, the bottom of the monitoring port is closed through thecover, the cover protrudes into the stirring box, and at least one near infrared detection probe connected with the near infrared detector and facing soil in the stirring box are arranged in the cover. H-O peak value change in the soil is detected in real time through the probes to judge solid-liquid ratio of soil to water in the soil so as to judge stirring uniformity of the soil and a solidifying and stabilizing agent, so that reasonable agent adding is ensured, and economic maximization is realized.

Description

technical field [0001] The invention belongs to the field of ectopic restoration of polluted soil, and in particular relates to a stirring equipment for online near-infrared spectrum monitoring of soil stabilization process. Background technique [0002] Nowadays, in the field of ex-situ remediation of contaminated soil, solidification and stabilization technology is the most widely used technology in the field of ex-situ remediation of soil. However, when adding solidification and stabilization agents to the soil, on the one hand, there will be uneven mixing between the agents and the soil. On the other hand, there will be problems such as agglomeration and agglomeration between soils. In addition, the Lambert-Beer law can describe the transmission mechanism of light. It can be said that the Lambert-Beer law is the basis of visible-near-infrared spectral analysis. A basic understanding of this law is that the measured substance absorbs visible-near-infrared light, and the ...
