Embodiment 1

[0087] like Figure 1-2 As shown, the small domestic waste pyrolysis gasification incinerator proposed in the embodiment of the present invention includes: a furnace body 1, a grate 5, a smoke collecting pipe 3, a pyrolysis gas output pipe 13, a secondary combustion chamber 17, a slag collecting pipe bucket 7;

[0088] The inside of the furnace body 1 is a cavity, and the top is provided with a feeding port 9 and a feeding door 10 that can be sealed with the feeding port 9; in order to facilitate the control of the opening and closing state of the feeding door 10, in this embodiment, the A feed gate drive mechanism 11 is provided between the feed gate 10 and the top of the furnace body 1 .

[0089] The grate 5 is located in the furnace body 1 and divides the cavity of the furnace body 1 into an upper furnace chamber 2 and a lower ash cavity 6; that is, the grate 5 and the furnace body 1 The space enclosed by the inner surface of the side wall, the top, and the feeding door 1...

Embodiment 2

[0114] The pyrolysis gasification method of the small domestic waste pyrolysis gasification incinerator of the present embodiment, such as Figure 7 As shown, it is realized by the small-scale domestic waste pyrolysis gasification incinerator described in Example 1, which includes the following steps:

[0115] The garbage moves from top to bottom in the furnace 2, and forms an oxygen-free preheating drying zone 30, an oxygen-free pyrolysis gasification zone 31, and an oxygen-depleted atmosphere from top to bottom in the furnace 2. Deep burning zone 32, burnout zone 33 in oxygen-enriched atmosphere.

[0116] Specifically, the garbage enters the furnace chamber 2, and firstly, enters the preheating and drying zone 30 in an oxygen-free atmosphere (here, "anaerobic" refers to an extremely oxygen-depleted state that is almost oxygen-free), where the garbage is preheated and dried. The zone 30 is preheated and dried, and in the process of preheating and drying, it gradually moves t...

Abstract

The invention provides a small household garbage pyrolysis and gasification incinerator. The small household garbage pyrolysis and gasification incinerator comprises an incinerator body, a fire grate, a smoke collecting pipe, a pyrolysis gas output pipe, a secondary combustion chamber and a slag collecting hopper. The invention further provides a pyrolysis and gasification method of the small household garbage pyrolysis and gasification incinerator. According to the small household garbage pyrolysis and gasification incinerator and the pyrolysis and gasification method thereof, the household garbage can be better subjected to continuous pyrolysis reaction in the incinerator, less external input energy is needed in the pyrolysis reaction process, the fluctuation of the hearth reaction state is smaller, the pyrolysis gas components and temperature are more stable, the ash ignition loss rate is lower, and the combustion efficiency is improved. Therefore, the operation efficiency of the incinerator is improved, the stable operation of the secondary combustion chamber is facilitated, the load impact of a downstream flue gas treatment system is reduced, and the comprehensive operation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of domestic waste treatment, in particular to a small-scale domestic waste pyrolysis gasification incinerator and a pyrolysis gasification method. Background technique [0002] Compared with other domestic waste treatment methods, incineration has obvious advantages such as rapid reduction, complete harmlessness, less total pollution emissions, high degree of resource utilization, and low environmental risks, and is the mainstream of domestic waste treatment at home and abroad. Direction of development. There are two main modes of domestic waste incineration treatment: one is to use a large-scale incineration system for incineration power generation after large-scale concentration, and the other is to adopt a decentralized incineration treatment mode according to local conditions according to the distribution characteristics of domestic waste. Both methods have their advantages. [0003] Compared with larg...
