Abstract

The invention discloses a soil remediation system for heating based on heat conduction oil. The soil remediation system comprises a soil abnormal-site thermal desorption tower, wherein a cylindrical soil abnormal-site thermal desorption cavity with an opening upper end is formed in the soil abnormal-site thermal desorption tower, a vertical discharging pipe is communicated to the bottom of the soil abnormal-site thermal desorption tower, a bent pipe is communicated to the bottom end of the vertical discharging pipe, and a discharging hole of the bent pipe is horizontally formed. The soil remediation system is simple in structure, and volatile gas produced in the soil abnormal-site thermal desorption cavity is sucked into a movable air suction pipe through a negative-pressure air suction effect of the movable air suction pipe and is then discharged into a tail gas treatment device, so that the situation that volatile matters discharged through thermal adsorption are remained in the soilabnormal-site thermal desorption cavity or discharged into the atmosphere to pollute the atmosphere is effectively prevented.

Description

technical field [0001] The invention belongs to the field of soil remediation, and in particular relates to a soil remediation system and method based on heat conduction oil heating. Background technique [0002] Existing soil thermal desorption often directly uses flames to heat the soil source in the soil thermal desorption chamber at a high temperature, which is likely to cause additional oxidation and decomposition in the soil source due to excessive temperature. And other chemical reactions, causing secondary pollution.
