Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and relates to a device for repairing soil polluted by volatile organic compounds. Background technique [0002] In recent years, with the rapid development of modern industry and the acceleration of urbanization, there have been a large number of chemical enterprises that have been relocated or will be shut down in my country. However, due to the lack of awareness of environmental protection and poor management of these enterprises in the past production and operation, a large amount of toxic and harmful substances, especially organic pollutants, entered the soil, causing serious site soil pollution problems. [0003] Most of the organic pollutants in the soil are volatile, and have "teratogenic", "carcinogenic", and "mutagenic" effects, which seriously threaten human health and environmental safety. In recent years, due to the concentrated emergence of environmental accidents a...
