Indirect heated fluidized bed apparatus with interpolated heating tubes for oil contaminated soil restoration

摘要

A heated apparatus for restoring oil contaminated soil, comprising: (1) a fluidized bed thermal desorption system for desorbing oil in an oil contaminated soil, and (2) a low temperature heat equipped with an oxidation catalyst for combusting the oil desorbed in the fluidized bed thermal desorption system. Fracture system, (3) located between the fluidized bed thermal desorption system and the low temperature thermal destruction system to form a multi-stage structure with these systems (1, 2), and the heat of combustion of the desorbed oil content generated in the thermal destruction system Oil contaminated soil recovery consisting of a heating tube system for providing a heat source of the fluidized bed thermal desorption system, and (4) a circulation system for allowing gases in and out of the systems (1, 2, 3) to circulate organically with one another. An indirect heated fluidized bed apparatus with interpolated heating tubes for a method and a method for recovering soil contaminated with oil using the apparatus are disclosed. have.;By using an indirect heated fluidized bed apparatus according to the present invention, it is possible to maximize the use of energy to restore oil contaminated soil with high efficiency.
