Embodiment Construction

[0015] The present invention is described below in conjunction with accompanying drawing:

[0016] The self-circulation filtration method in the solid waste pyrolysis incineration proposed by the present invention is used in the pyrolysis incineration process of the solid waste pyrolysis incineration system. The method is that the residue obtained after pyrolysis and incineration is crushed by the crushing section, and then circulated to the cloth section, where it is laid on the bottom of the incineration unit 1 as a base material, used as the filter layer 2 of the incineration unit, and then clothed on the filter layer Incineration material 3, the material to be incinerated can be waste incineration fly ash, chemical waste salt, organic silicon slurry residue, oil sludge, domestic sludge, chemical sludge, printing and dyeing sludge, rectification residue, leather sludge, electroplating sludge, chromium slag and other solid waste, such as figure 1 shown.

[0017] In this em...

Abstract

The invention discloses a self-circulation filtering method in solid waste pyrolysis incineration. The method comprises the following steps: crushing incinerated residues, circularly taking the crushed residues as a filtering layer of an incineration unit, and paving the residues at the bottom of the incineration unit. The filtering method reduces dusts in the incineration process, solves the problem of hardening of the residues in the incineration process, further improves the stability and reliability of the process system, and is suitable for pyrolysis incineration disposal of solid wastessuch as waste incineration fly ash, chemical waste salts, organic silicon slurry residues, oil sludge, domestic sludge, chemical sludge, printing and dyeing sludge, rectification residues, leather sludge, electroplating sludge and chromium residues.

Description

technical field [0001] The invention relates to the technical field of solid waste treatment, in particular to a technology for harmless disposal of solid waste and hazardous waste through pyrolysis and incineration. Background technique [0002] For the field of solid waste incineration, the traditional rotary kiln and fluidized bed incineration methods have a large amount of dust, especially for materials with high calorific value, the incineration temperature is high, and it is easy to produce viscous substances such as tar, which is very easy to cause problems such as pipeline blockage and material compaction. Cause the system to run abnormally, the continuity is not high, and the material burning loss rate is high. The large amount of dust also leads to a bad working environment, which is not conducive to the physical and mental health of operators. [0003] Therefore, there is a need for a new technology that solves the problem of large dust and hardened adhesives in ...
