Problems solved by technology

[0007] 2. With the increasing amount of garbage generated and piled up like mountains, the amount of garbage treatment must be effectively increased in order to meet market demand
[0010] Existing gasification incinerators, such as the following two invention patents: Multi-column segmented drive compound domestic waste incinerator (ZL200710092508.9) and two-stage waste incinerator (ZL201010268376.2) Unsolved problems: heat treatment of waste The mode is relatively backward, just drying-burning-burning, the process of solid combustion releasing heat; the thermochemical reaction in the furnace is dominated by oxidation reaction, supplemented by reduction reaction, which is easy to produce secondary pollutants; when garbage is burned in the furnace, the peroxygen coefficient Large, large amount of primary air and secondary air supply, high dust content in flue gas, great impact on heat energy recovery system and flue gas treatment system, easy to accumulate dust, large amount of flue gas, reducing heat conversion efficiency; Without a separate gasification furnace and ember furnace, waste can only be processed in batches, and large-scale continuous gasification and incineration of waste cannot be realized, and the amount of waste treated is small

Embodiment Construction

[0040] see figure 1 , is a preferred embodiment of the mechanical grate type garbage gasification incinerator, the gasification incinerator 1 includes a grate 101, and feed bins 102, which are sequentially arranged along the feed direction on the grate 101 The gasification furnace 103 and the ember furnace 104, the rear of the ember furnace 104 is the slag outlet of the ember furnace 104, the gasification furnace 103 mainly gasifies the charcoal part of the garbage, and discharges combustible gasification flue gas and garbage residues, the ember furnace 104 mainly performs combustion treatment of residual charcoal, and discharges harmless ash. The hearth 105 of the gasification furnace 103 and the ember furnace 104 adopts a mechanical grate type movable hearth 105 independently driven by sections. The plates are stacked front and back, arranged alternately and gathered together. Multiple groups of adjacent movable grate plates are connected by tie rods and driven by a set of ...

Abstract

The invention discloses a mechanical grate type waste gasifying incinerator and a processing method thereof. The gasifying incinerator comprises a feed bin, a gasifying furnace and a burning furnace, wherein the burning furnace is positioned on the front lower part of a slag dropping opening of the gasifying furnace, a stockpile sealing section is formed between the feed bin and the gasifying furnace, a residue stoker is arranged between the gasifying furnace and the burning furnace, the upper ends of the gasifying furnace and the burning furnace are respectively arched, and smoke outlets are respectively formed in the upper ends of the gasifying furnace and the burning furnace. The waste processing method comprises the steps of A. igniting and drying; B. burning waste in a hearth of the gasifying furnace; C. performing continuous gasification and incineration on the waste; D. shutting off the mechanical grate type waste gasifying incinerator after the waste and waste residues are burnt out. When the mechanical grate type waste gasifying incinerator is used for processing the waste, the waste conveying capability is strong, the waste processing capacity is large, the heat recovering efficiency is high, and the pollutant discharge can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of solid waste incineration treatment, and in particular relates to a mechanical grate type garbage gasification incinerator and a treatment method thereof. Background technique [0002] The existing waste treatment technologies mainly include incineration, sanitary landfill, composting, and waste recycling. Among the conventional waste treatment technologies, incineration has the advantages of obvious reduction effect, complete harmlessness, small land occupation, utilization of waste heat energy, and less secondary pollution, which meets the strategic requirements of my country's sustainable development. However, with the continuous improvement of environmental protection requirements at home and abroad, how to strengthen the control of secondary pollution is particularly important. Therefore, waste pyrolysis and gasification incineration technology is gradually pushed to the road of industrial applicatio...
