A safe regeneration equipment for chemical remediation of heavy metal polluted soil

Abstract

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, comprising a housing, the left and right sides of the lower surface of the housing are fixedly connected with electrode rods, the lower surface of the housing and A loose plate is slidably connected to the inner side of the electrode rod, and a fixed seat is fixedly connected to the top end of the inner surface of the casing. The expansion shell inside the shell is heated and expands, which generates an upward thrust on the fixed plate. When the fixed plate is forced to slide upward inside the fixed plate, the slider is pushed to slide on the outer surface of the limit rod through the connecting rod. When the slider When the outer surface of the limit rod slides, the slider drives the slider on the upper surface to slide on the slider, and at the same time the contact position between the slider and the resistance rod changes, which increases the access resistance of the equipment and reduces the penetration of the equipment into the soil. The high voltage makes the equipment have the highest purification efficiency of the soil, and avoids incomplete soil purification due to excessive soil temperature.

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...

AI Technical Summary

Problems solved by technology

[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 excessive voltage, and the soil heat will lead to poor soil purification effect. Therefore, those skilled in the art Provides heavy metal-contaminated soil chemical remediation safe regeneration equipment to solve the problems raised in the above-mentioned background technology
