Equipment for fertility-increasing thermal desorption soil remediation

Abstract

The invention discloses equipment for fertility-increasing thermal desorption soil remediation, and relates to the technical field of soil remediation. The equipment for fertility increasing type thermal desorption soil remediation comprises a bearing plate, three sets of bearing columns are fixedly installed at the top of the bearing plate, two sets of discharging openings are formed in the bearing plate, a thermal desorption box is arranged at the top of the bearing plate, a fermentation manure tank is welded to the outer surface of the top of the bearing plate, and rotating columns are rotatably installed on the adjacent side walls of the two sets of bearing columns. According to the equipment, soil subjected to thermal desorption and a fertilizer can be added into a mixing box according to a certain proportion, the situation that the fertilizer increasing effect is poor or excessive due to proportion imbalance is avoided, the follow-up soil fertilizer increasing effect is effectively guaranteed, the quantitative proportion is adjustable, and the diversity of the fertilizer increasing proportion is enhanced. Loss caused by the fact that the quantitative proportion cannot be adjusted due to different properties of soil in all places is avoided, the error-tolerant rate of the equipment is increased, and a foundation is effectively laid for next-step mixed fertilization.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a device for fertilization-type thermal desorption soil remediation. Background technique [0002] Soil remediation is a technical measure to restore contaminated soil to normal functions. 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 types: physical, chemical and biological. Methods; Since the 1980s, many countries in the world, especially developed countries, have formulated and carried out contaminated soil treatment and remediation plans, so a new soil remediation industry has also formed. [0003] The existing partial fertilization-type thermal desorption soil repair equipment has poor thermal desorption effect and uneven heating, and there will be residual pollutants in some soils, and the subsequent fertilizati...

AI Technical Summary

Problems solved by technology

[0003] The existing partial fertilization-type thermal desorption soil repair equipment has poor thermal desorption effect and uneven heating, and there will be residual pollutants in some soils, and the subsequent fertilization of the thermal desorption soil is not carried out according to the following regulations. A certain proportion of mixed fertilizers for fattening often results in poor fattening effects or excessive fattening, which will cause certain effects
