Vertical type pyrolysis device for solid organic waste

Abstract

The invention relates to a vertical type pyrolysis device for a solid organic waste, and belongs to the technical field of pyrolysis of organic matters. The vertical type pyrolysis device for the solid organic waste comprises a furnace wall, a thermal insulation layer, a transmission shaft, a resistor disc, scraping plates, trays, guide plates, guide canopies, a feed port, a discharge port and a pyrolysis gas outlet; the resistor disc is arranged on the inner wall of the thermal insulation layer of the furnace wall; the feed port is formed in the upper part; the scraping plates arranged in a layered manner are fixed on the transmission shaft and on the trays arranged in a layered manner; the guide plates are fixed on the inner sides of the trays; the guide canopies are arranged on the lower sides of the guide plates; the pyrolysis gas outlet is formed in the furnace wall; and a residue produced after the pyrolysis is discharged from the discharge port in the bottom part. The vertical type pyrolysis device for the solid organic waste adopts a vertical structure, has the advantages of small occupied area, and is suitable for the working place having high space requirements, the multi-stage shearing is adopted, the heat transfer rate is high, coking is not caused easily, the distribution of heat is even, the heat loss is low, and the pyrolysis cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of pyrolysis of organic matter, in particular to a vertical pyrolysis device for solid organic waste. Background technique [0002] At present, the common furnace types for pyrolysis of organic solid waste mainly include fixed bed, rotary kiln, fluidized bed and other types. The main reactors of these furnace types have their own advantages in the pyrolysis process of solid organic waste, but there are also many problems. The fixed bed mainly has two forms: a built-in screw propeller and a built-in agitator. In order to ensure thermal efficiency, both of them use a horizontal reactor, and the horizontal reactor occupies a relatively large area; the rotary kiln also uses a horizontal reactor. Type reactor, which occupies a large area. In addition, during the operation, the tightness of the reactor is required to be high, and the construction cost is high; the fluidized bed is a pyrolysis method with high heat...

AI Technical Summary

Problems solved by technology

The fixed bed mainly has two forms: a built-in screw propeller and a built-in agitator. In order to ensure thermal efficiency, both of them use a horizontal reactor, and the horizontal reactor occupies a relatively large area; the rotary kiln also uses a horizontal reactor. Type reactor, which occupies a large area. In addition, during the operation, the tightness of the reactor is required to be high, and the construction cost is high; the fluidized bed is a pyrolysis method with high heat transfer efficiency, but in the reaction process It needs gas as a medium to propel the material to form a fluidized state. It needs to use inert gas such as nitrogen as the fluidized gas source. However, it has high requirements for material pretreatment, complicated process operation, high operating costs, and a series of problems such as not being suitable for industrial applications.
