Heating kiln for restoring polluted soil

Abstract

The invention discloses a heating kiln for restoring polluted soil. The heating kiln comprises a kiln body, wherein one end of the kiln body is provided with a feeding port and the other end of the kiln body is provided with a discharging port; the feeding port and the discharging port are rotatably arranged on the end surface of the kiln body by a rotary bearing; a plurality of heating tiles are uniformly arranged on the side wall of the inner part of the kiln body along the circumferential direction; a plurality of temperature sensors are uniformly and dispersedly arranged on the inner end wall of the kiln body; a temperature display is also arranged on the kiln body. The heating kiln disclosed by the invention has the advantages that by adoption of the technical scheme, the rotation of the heating kiln can be realized, so that the heating is uniform; due to combination of the temperature sensor and the temperature display, the temperature of soil in the heating kiln can be displayed in real time; the structure is simple and the installation is convenient.

Description

Technical field [0001] The invention relates to the field of environmental protection, in particular to a heating kiln used for contaminated soil restoration. Background technique [0002] Among the contaminated soil remediation methods, there is an incineration method that directly burns the contaminated soil. Its steps are simple and quick and convenient to implement, but it is easy to destroy the nature of the soil itself and make the soil lose its original function. If a more gentle method is used, By thermally analyzing the pollutants in the soil at a not too high temperature, the original functions of the soil can be retained to a large extent. This method requires a special heating kiln for heating the soil, which can evenly heat the soil and in real time The temperature in the kiln is fed back, and the temperature is adjusted manually, so that the temperature in the kiln is always at an appropriate level. Summary of the invention [0003] The purpose of the present invent...

[0002] Among the contaminated soil remediation methods, there is an incineration method that directly incinerates the contaminated soil. The steps are simple and the implementation is quick and convenient, but it is easy to destroy the nature of the soil itself and make the soil lose its original function. If a milder method is adopted, Thermal analysis of pollutants in the soil at a temperature that is not too high can retain the original function of the soil to a large extent, and this method requires a special heating kiln for heating the soil, which can heat the soil evenly and in real time Feedback the temperature in the kiln, adjust the temperature manually, so that the temperature in the kiln is always at an appropriate level
