Problems solved by technology

At present, the structure of the single-tube thermal desorption kiln body cannot realize the separation of particle size, so as to strengthen the desorption of coarse-grained soil in a targeted manner
In order to ensure that the coarser particles can be effectively repaired up to the standard, the desorption temperature or acceptance desorption time can only be increased, which ultimately leads to low repair efficiency and high energy consumption

Abstract

The invention discloses a high-efficiency energy-saving thermal desorption kiln body mechanism for organic contaminated soil remediation, which comprises a double-cylinder kiln body unit, sieve poresand a material raising plate, and the double-cylinder kiln body unit comprises a thermal desorption kiln body and a sieve-shaped roller for size grading of large and small granular soil. By means of the mode, the efficient and energy-saving thermal desorption kiln body mechanism for organic contaminated soil remediation utilizes a double-cylinder structure to conduct particle size grading on soil,so that in the desorption process of strengthening coarse particles, the desorption efficiency of fine particles is improved, and energy conservation and synergy are achieved.

Description

technical field [0001] The invention relates to the field of soil remediation, in particular to a large-scale modularized thermal desorption kiln equipment with high efficiency and energy saving applied to the remediation of organic polluted soil. Background technique [0002] Ex-situ thermal desorption technology, as one of the main technologies currently used to remediate organic contaminated soil, can be divided into direct thermal desorption and indirect thermal desorption equipment, of which the former is more widely used. One of the core units of thermal desorption equipment is the soil thermal desorption kiln body, and its structural design directly affects the efficiency of soil thermal desorption and system energy consumption. At present, direct thermal desorption kilns with various structures have been developed at home and abroad, but the kilns are all single-tube structures. The flue gas is fully exposed, thereby improving the repair efficiency. [0003] Organi...
