Continuous microwave soil remediation device

Abstract

The invention discloses a continuous microwave soil remediation device, which comprises a feeding machine, a catalytic reactor feeding sieve, conveyer belt, a microwave resonant cavity, microwave generation equipment, exhaust gas recovery equipment, a blast heater, a recovery belt, catalyst recovery equipment and a PLC control center. According to the invention, with the combination of microwave and thermal desorption and with the assistance of aerodynamic force, soil pollutants are separated at the minimum energy consumption and at the fastest speed. When in use, the device provided by the invention has characteristics of high efficiency, easy operation, safety, reliability, environmental protection and the like.

Description

technical field [0001] The invention belongs to the technical field of soil restoration, and in particular relates to a continuous microwave soil restoration device. Background technique [0002] In recent years, with the continuous acceleration of the industrialization process, the unreasonable exploitation of mineral resources and their smelting discharge, the long-term sewage irrigation and sludge application to the soil, the atmospheric deposition caused by human activities, and the application of chemical fertilizers and pesticides have caused Soil pollution is serious, and severe soil pollution causes great harm. It is estimated that 12 million tons of grains are polluted by heavy metals nationwide every year, causing direct economic losses of more than 20 billion yuan. In addition, in the current urban construction and development, most of the polluting enterprises have been relocated out of the city one after another, and the vacated land is increasingly becoming a "...

AI Technical Summary

Problems solved by technology

Experiments have proved that the critical action of microwave at a certain temperature can quickly gasify pollutants and achieve the purpose of separating pollutants from the soil, but the pure microwave method also has some unsatisfactory effects on the remediation of contaminated soil.
