Internal and external dynamic heating solid organic matter pyrolysis combination device in double-column mixing process

Abstract

The invention discloses an internal and external dynamic heating solid organic matter pyrolysis combination device in double-column mixing process. The device comprises a plurality of pyrolysis chambers and heating chambers, wherein each heating chamber is internally provided with a one-process flue and a multi-process flue capable of forming a fold-back heating passage, and heating gas in each two adjacent heating chambers flow reversely; each pyrolysis chamber is internally provided with two columns of agitators, and each column of agitator is provided with a single-process heating agitatorand a multi-process heating agitator which are connected in parallel with each other, the multi-process heating agitators can form a fold-back stirring / heating passage through a communicating pipeline, and heating gas in the two columns of agitators flow reversely; the agitators are driven to rotate through external power; a feeding device and a pyrolysis gas output device are arranged at the topof each pyrolysis chamber, and a discharging device is arranged at the bottom of each pyrolysis chamber. The internal and external dynamic heating solid organic matter pyrolysis combination device enlarges the heating area, reduces the thermal resistance, ensures uniform heating and high heat transfer efficiency, and increases the gas permeability. The pyrolysis chambers can be copied and combined, and are suitable for large-scale industrial production. The internal and external dynamic heating solid organic matter pyrolysis combination device provides strong protection for material pyrolysis,is high in operation adaptability and productivity, and has efficacies of environmental protection, energy conservation and safety.

Description

technical field [0001] The invention relates to a combined device for dynamically heating solid organic matter pyrolysis inside and outside a dual-row mixing process, which belongs to the field of solid organic matter cracking and is used for solid organic matter pyrolysis and drying of solid organic matter. Background technique [0002] Every year, a large amount of solid organic matter needs to be processed in our country. Waste solid organic matter generally includes waste plastics, waste rubber, residual oil, oil shale, low-rank coal powder, straw, wood chips, etc., especially the waste plastics contained in the growing urban waste. , Waste rubber solid organic matter, the general method of dealing with these waste solid organic matter is landfill, incineration, cracking. [0003] Landfilling needs to occupy a large amount of land and farmland, and at the same time pollute the groundwater body. Since waste plastics and waste tires are solid organic matter that is difficu...

AI Technical Summary

Problems solved by technology

[0004] Pyrolysis is a method of thermal anaerobic cracking. At present, there are three methods at home and abroad: Horizontal rotary kiln is generally used in China. This kind of equipment is manually operated intermittently, causing serious pollution, high energy consumption, high labor intensity, unsafety, and low production capacity. Therefore, it is strictly restricted by national and local government policies

New technologies of electric energy, such as light wave cracking, plasma cracking, electromagnetic pyrolysis, intermediate frequency pyrolysis, etc., cannot be applied due to the high production cost of electricity consumption

Continuous equipment has low pollution, low energy consumption, safety and stability. Several domestic companies have developed horizontal continuous pyrolysis production equipment, but they have not been popularized and applied due to structural problems, sealing problems, and low production capacity.
