The invention relates to a device for remedying soil contaminated by volatile organic compounds. The device for remedying the soil contaminated by the volatile organic compounds comprises a heating control system, a thermal desorption pipe arranged in the heating control system, a rotation control system in transmission connection with the thermal desorption pipe, an air inlet pipeline system and an air outlet pipeline system, wherein the air inlet pipeline system and the air outlet pipeline system are arranged at the two ends of the thermal desorption pipe. A plurality of tooth-shaped shoveling plate are arranged on the inner wall of the thermal desorption pipe. A multi-hole dust filter screen is further arranged at the end, connected with the air outlet pipeline system, of the thermal desorption pipe. The air outlet pipeline system is communicated with an external tail gas absorption system. Compared with the prior art, the device is simple and compact in overall structure and good in sealing performance; by the adoption of the heating control system and the rotation control system, automatic control over heating and rotation can be achieved; operation is easy, and working efficiency is greatly improved; the device is economical and practical; the heat energy utilization rate is high, and the remediation cost is greatly reduced.
