Problems solved by technology

[0005] In the existing pyrolysis technology, the organic matter is mainly pyrolyzed by burning part of the raw materials to generate hot flue gas. The internal heating method will make it difficult to guarantee the quality of the pyrolysis product, and the resource utilization effect is poor.
If the external heating method is used, the heating efficiency will be low, and there is a defect that

Abstract

The invention provides an organic matter self-energy-supply drying and pyrolysis and full-component recycling system and a technology method, and belongs to the technical field of solid waste recycling and environments. The system comprises a feeding bin, a drying device, a condenser, a water treatment device, a pyrolyzing furnace, an oil storage tank set, a gas storage tank, a combustion furnace and the like. Before original organic matter is subjected to pyrolysis, the original organic matter enters the drying device to be dried, the water content of the organic matter is reduced, and therefore the pyrolysis effect of the organic matter is enhanced, and the water content in product oil is low. Semicoke and noncondensing combustible gas generated through pyrolysis are conveyed into the combustion furnace to be combusted, energy is recycled, pollution to the environment from waste residues and waste gas is prevented, accordingly, the effect of zero emission of pollutants is achieved, and therefore the emission standard for the pollutants can be met. Due to the fact that drying and pyrolysis in the technology are separated, energy all comes from the combustion heat of pyrolysis residues, consumption of auxiliary fuel is reduced, and the organic matter self-energy-supply drying and pyrolysis and full-component recycling system and the technology method have high economic efficiency in the aspects of solid waste treatment and energy recycling.

Description

technical field [0001] The invention relates to a self-energy-supplied drying and pyrolysis of organic matter, a whole-component recycling system and a process method, belonging to the technical field of solid waste recycling and environment. Background technique [0002] With the development of industrial production and the improvement of human material life, there are more and more types of organic waste, and the amount of production is increasing. The harmless treatment of organic waste is difficult and costly, and ordinary treatment methods will cause environmental pollution. Moreover, organic waste has great value in recycling, especially in the context of energy depletion worldwide. [0003] Traditional methods of treating organic waste include: landfill, composting, incineration, etc. However, with the rapid increase of organic waste, traditional methods have increasingly shown their defects, such as landfilling takes up a large area of ​​land, composting has a small ...
