A self-sustaining smoldering organic waste pyrolysis oil production equipment and method

Abstract

The invention belongs to the technical field of waste disposal, and discloses a self-sustaining smoldering organic waste pyrolysis oil-making equipment and method. The equipment includes a material conveying component, a smoldering component, a condensation separation component and a flue gas purification component. The material conveying component, the smoldering component, the condensation separation component and the flue gas purification component are connected in sequence; the mixed material moves from top to bottom in the smoldering component, and is discharged as ash through the smoldering reaction during the movement. During the process of material accumulation in the smoldering component, the pyrolysis reaction is stimulated by the heat generated by the smoldering reaction at the bottom of the smoldering component, and the generated pyrolysis gas moves from bottom to top with the flue gas to the condensation separation component. And the flue gas purification component is used to condense and purify the flue gas from the smoldering component in sequence, and the purified flue gas obtained is discharged from the equipment. The invention couples two chemical processes of smoldering and pyrolysis, reduces energy consumption and improves integration.

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.

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
