Pyrolysis device and method for solid organic waste

Abstract

The invention discloses a pyrolysis device and method for solid organic waste. The pyrolysis device comprises a pyrolysis furnace, wherein the pyrolysis furnace comprises a shell, a rotating shaft, asealed feeding device and a discharging part; the shell is horizontally arranged, a pyrolysis chamber is defined in the shell, one end of the shell is a feeding end, the other end of the shell is a discharging end, and the side wall of the shell is provided with clamping sleeves; a plurality of partition plates are arranged in the clamping sleeves at intervals in the horizontal direction to dividethe clamping sleeves into multiple independent sub clamping sleeves, and each sub clamping sleeve is independently provided with a hot air inlet and a cold air outlet; the rotating shaft is horizontally arranged in the pyrolysis chamber, a plurality of shovelling plates are fixedly arranged on the rotating shaft in the length direction, and the rotating shaft rotates to drive the shovelling plates to do circumferential motion; the sealed feeding device is connected with the feeding end of the shell; the discharging part is connected with the discharging end of the shell and provided with a pyrolysis oil gas outlet and a discharging port. By adopting the pyrolysis device, the energy consumption can be obviously reduced, and the pyrolysis efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of harmless treatment and resource utilization of solid organic waste, in particular, the invention relates to a pyrolysis device and a pyrolysis method for solid organic waste. Background technique [0002] In environmental protection, energy, and chemical production, the conversion process of some materials often requires processes such as pyrolysis, gasification, carbonization, activation, reaction, and cooling, and these processes generally rely on different rotary kilns. The existing rotary furnace usually consists of a drum, a furnace head and a furnace tail. The furnace head and the furnace tail are fixedly connected around the two ends of the drum to rotate and seal, and are dynamically and statically sealed with the two ends of the drum. The drum is driven by an external drive device. Rotate continuously in one direction. Since the existing rotary kilns are all rotated by the outer cylinder, the en...

AI Technical Summary

Problems solved by technology

Since the existing rotary kilns are all rotated by the outer cylinder, the energy consumption is high; at the same time, when hot air is used for heating, the hot air usually enters from one section of the cylinder and escapes from the other end, so it can only be achieved by controlling the temperature at the inlet end. Provides heat, resulting in too high temperature at the inlet or too low temperature at the outlet
