Abstract

The invention relates to the technical field of soil remediation, in particular to safe regeneration equipment for chemical remediation of heavy metal contaminated soil. The equipment comprises a shell, electrode bars are fixedly connected to the left side and the right side of the lower surface of the shell, and relaxation plates are slidably connected to the positions, located on the inner sidesof the electrode bars, of the lower surface of the shell. The top end of the inner surface of the shell is fixedly connected with a fixed seat. An expansion shell in the shell is heated to expand togenerate upward thrust on a fixing plate, when the fixing plate is stressed and upward sliding happens in the fixing plate, a sliding block is pushed to slide on the outer surface of a limiting rod through a connecting rod, and when the sliding block slides on the outer surface of the limiting rod, the sliding block drives a sliding piece on the upper surface of the sliding block to slide on the sliding rod. Meanwhile, the contact position of the sliding sheet and a resistance rod is changed, so that the access resistance of the equipment is improved, the voltage introduced into soil by the equipment is reduced, the soil purification efficiency of the equipment is highest, and incomplete soil purification caused by over-high soil temperature is avoided.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a safe regeneration equipment for chemical remediation of heavy metal polluted soil. Background technique [0002] Soil remediation is a technical measure to restore the normal function of polluted soil. In the soil remediation industry, there are more than one hundred existing soil remediation technologies, and there are more than ten commonly used technologies, which can be roughly divided into three methods: physical, chemical and biological. Since the 1980s, many countries in the world, especially developed countries All countries have formulated and carried out contaminated soil treatment and restoration plans, so a new soil restoration industry has also been formed [0003] However, when the heavy metal contaminated soil chemical remediation safety regeneration equipment uses the electrode rod to apply voltage to the soil during use, the soil may heat up due to ex...
