Solid waste thermal cracking incinerator

Abstract

The invention belongs to the technical field of solid waste treatment, and relates to a solid waste thermal cracking incinerator which comprises a thermal cracking chamber and a disturbance device in the thermal cracking chamber. The disturbance device comprises a rotating pipe and a V-shaped guide plate, the inner side walls of two side plates of the V-shaped guide plate are externally tangent to the outer wall of the rotating pipe, and the two ends of the disturbance device are connected with the side walls of the thermal cracking chamber respectively; the driving device is connected with the two ends of the rotating pipe, so that the rotating pipe of the disturbance device rotates and stops within the range of 360 degrees relative to the side wall of the thermal cracking chamber. The problems of burning through, burning deviation, flameout and the like in the solid material burning process are solved, and the whole system can operate continuously and stably.

Description

technical field [0001] The invention belongs to the technical field of solid waste treatment, and in particular relates to a thermal cracking incinerator for solid waste. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] At present, large and medium-sized centralized direct combustion incineration power generation and small and medium-sized distributed thermal cracking incineration are the main ways to reduce the amount of solid waste that can be combusted, such as domestic waste, and some other fields that require thermal cracking and incineration. . For hilly mountainous areas or county-level urban areas where domestic waste generation is small, the investment and operat...

AI Technical Summary

Problems solved by technology

For hilly mountainous areas or county-level urban areas where domestic waste generation is small, the investment and operation costs of large and medium-sized centralized incineration power generation projects are relatively high, and waste raw materials are not convenient for long-distance transportation, and the heat produced is inconvenient for local recycling, so it is not suitable for Household waste is incinerated separately for power generation. At present, the thermal cracking process is mainly used for reduction disposal

[0004] However, under the background of no large-scale promotion of classified collection and disposal of domestic waste or poor classification, the composition of domestic waste materials is complicated, the moisture content is high, and there is generally no independent sorting or drying process before pyrolysis

The existing small and medium-sized distributed domestic waste thermal cracking systems mostly adopt the fixed-bed simmering process. Due to the uneven characteristics of the waste raw materials and the defects of the furnace body structure, it is easy to cause problems such as burn-through and partial burning, flameout, and smoke leakage. As a result, continuous and stable operation is not possible, the amount of waste disposal is limited, the tar and dioxin-like harmful substances in the flue gas are not completely decomposed, and additional fuel needs to be supplemented. It is difficult to meet the technical specifications for domestic waste incineration treatment
