Problems solved by technology

[0006] However, in the existing technology, when the soil is put into the restoration cylinder for treatment, it is easy to accumulate together, resulting in a low contact rate between the soil and the steam, which prolongs the restoration time and reduces the restoration efficiency. These problems are studied and improved; in order to solve the above problems, the design of this application is proposed

Embodiment Construction

[0036] In describing the present invention, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", The orientation or positional relationship indicated by "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than Nothing indicating or implying that a referenced device or element must have a particular orientation, be constructed, and operate in a particular orientation should therefore not be construed as limiting the invention.

[0037] see Figure 1-Figure 4 As shown, the technical solution adopted in this specific embodiment is: it includes: a repair cylinder 1; a load-bearing structure 2 for carrying polluted soil is arranged in the repair cylinder 1, and the load-bearing structure 2 can be a bearing plate; A steam cover...

Abstract

The invention discloses a heavy metal contaminated soil remediation system and a use method, and relates to the technical field of soil remediation. The system comprises a remediation cylinder; a bearing structure for bearing polluted soil arranged in the remediation cylinder; a steam cover I arranged above the bearing structure in the repairing cylinder; and a transmission structure in transmission connection with the bearing structure arranged at the bottom of the bearing structure. A vibration device connected with the transmission structure is installed on one side of the transmission structure. the vibration device drives a linkage shaft and a transmission plate to vibrate, the amplitude is transmitted to the transmission part, the transmission part drives the whole bearing structure to shake in the supporting block through the amplitude, when the bearing structure shakes, soil on the bearing structure can be shaken to be scattered, the contact area between steam and the soil can be increased, and the remediation efficiency is improved. A part of soil can be filtered out through the screen structure and falls onto the connecting plate, so that the phenomenon that the remediation treatment efficiency is low due to the fact that the soil is accumulated on the bearing structure is avoided.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a heavy metal-contaminated soil remediation system and an application method. Background technique [0002] Heavy metal pollution refers to environmental pollution caused by heavy metals or their compounds. It is mainly caused by human factors such as mining, exhaust gas discharge, sewage irrigation, and the use of heavy metal-exceeding products. Therefore, the remediation technology of heavy metal-contaminated soil has become a major research focus in the field of contaminated soil remediation technology. [0003] At present, the treatment methods of heavy metals mainly include biological enrichment method, soil replacement method, spray purification method and thermal desorption method. [0004] Among them, the thermal desorption method, that is, when dealing with heavy metal-contaminated soil, the soil is first broken, and then additives that can decompose heavy meta...
