Organic waste pyrolysis oil production equipment and method based on self-sustaining smoldering

Abstract

The invention belongs to the related technical field of waste disposal, and discloses organic waste pyrolysis oil production equipment and method based on self-sustaining smoldering. The equipment comprises a material conveying assembly, a smoldering assembly, a condensation separation assembly and a flue gas purification assembly, and the material conveying assembly, the smoldering assembly, thecondensation separation assembly and the flue gas purification assembly are connected in sequence; the mixed material moves in the smoldering assembly from top to bottom; in the movement process, ashslag is formed through smoldering reaction and is discharged; meanwhile, a pyrolytic reaction is excited by heat generated by the smoldering reaction at the bottom of the smoldering assembly in the stacking process of the mixed material in the smoldering assembly; the generated pyrolysis gas moves to the condensation separation assembly along with the flue gas from bottom to top, the condensationseparation assembly and the flue gas purification assembly are used for sequentially condensing and purifying the flue gas from the smoldering assembly, and the obtained purified flue gas is discharged from the equipment. Two chemical processes of smoldering and pyrolysis are coupled so that the energy consumption is reduced and the integration level is improved.

Description

technical field [0001] The invention belongs to the technical field related to waste disposal, and more specifically relates to a self-sustaining smoldering organic matter pyrolysis oil production equipment and method. Background technique [0002] A large amount of organic waste is generated in the production process of daily life, including agricultural waste (such as straw), municipal solid waste (such as kitchen waste, municipal pollution), industrial waste (such as oil residue), etc. How to dispose of it efficiently and scientifically is as above Organic waste and realizing recycling are the key points in the field of waste disposal at present. The organic part of organic waste is often the part of these waste components that accounts for a large volume, is difficult to decompose naturally, has high energy storage, and carries harmful substances such as insect eggs, bacteria, etc., and has high volatile content, high water content, Features low calorific value.

AI Technical Summary

Problems solved by technology

[0003] Traditional heat treatment methods such as pyrolysis can convert the organic part into pyrolysis oil and pyrolysis coke through pyrolysis (usually around 500°C), so as to realize the energy utilization of the products. However, traditional pyrolysis requires external continuous supply Heat source, especially for organic waste with low calorific value, the conversion process consumes too much energy, and the gain outweighs the gain
