Thermal desorption cylinder for soil remediation

Abstract

The invention relates to the field of soil remediation thermal desorption equipment, and discloses a thermal desorption cylinder for soil remediation. The thermal desorption cylinder comprises a cylinder body supported and fixed by a support; a feeding pipe is arranged on one side of the top of the cylinder body, a discharging pipe is arranged on the other side of the bottom of the cylinder body,and the cylinder body inclines downwards towards the discharging pipe. The middles of the two sides of the cylinder are movably sleeved with positioning rotating shafts, and one ends of the two positioning rotating shafts are fixedly connected with rotating plates located in the cylinder correspondingly. According to the thermal desorption cylinder for soil remediation, the support supports and fixes the cylinder, the rotating plate and the guide strips in the cylinder integrally rotate clockwise, high-temperature flue gas enters the front face of the cylinder to heat soil, the six guide strips are matched with the inner wall of the cylinder to continuously turn up the soil to be subjected to thermal treatment, and the soil to be subjected to thermal treatment is directly blown to the guide strips to drive the turned-up soil; when the soil is directly heated, the soil can be conveniently blown away by utilizing the pressure output by the flue gas, so that the soil is uniformly heated.

Description

technical field [0001] The invention relates to the field of thermal desorption equipment for soil restoration, in particular to a thermal desorption cylinder for soil restoration. Background technique [0002] Soil thermal desorption is a process in which organic pollutants in the soil are volatilized and separated by heating the soil at high temperature. In the existing soil thermal desorption treatment, thermal desorption drums are often used to generate high-temperature flue gas by burning with burner groups, and The high-temperature flue gas is transported into the drum, the drum rotates to turn the soil, and the high-temperature flue gas heats the soil to volatilize the organic pollutants in the soil, thereby remediating the polluted soil. [0003] However, the existing sudden thermal desorption process uses a drum, and the high-temperature flue gas flows from one side of the drum to the other side, and the same is true for the soil, which makes the flue gas flow longe...
