Combined pyrolysis gasifier

Abstract

The invention discloses a combined type pyrolysis and gasification furnace. The whole device comprises a horizontal furnace body, a vertical furnace body, a vapor leading device, a tar thermal cracking catalysis device and a cyclone dust removal device. The horizontal furnace body is perpendicularly communicated with the middle-lower portion of the vertical furnace body, the middle of the horizontal furnace body is communicated with the vapor leading device, and the other end of the vapor leading device is communicated with the middle-upper portion of the vertical furnace body. The lower end of the vertical furnace body is provided with a deslagging device, the interior of the upper end of the vertical furnace body is provided with the tar thermal cracking catalysis device which is communicated with the cyclone dust removal device through a combustible gas discharge pipeline. The horizontal furnace body is divided into a feeding section, a drying section and a pyrolysis and gasification section, the feeding section, the drying section and the pyrolysis and gasification section are combined into an inner-layer furnace body, the drying section and the pyrolysis and gasification section are combined into an outer-layer furnace body, the inner-layer furnace body stretches into the vertical furnace body, the outer-layer furnace body is connected with the barrel wall of the vertical furnace body, and the inner-layer furnace body and the outer-layer furnace body form an annular cavity. The combined type pyrolysis and gasification furnace is simple in structure, reasonable in design, high in continuous working capacity and high in pyrolysis and gasification efficiency.

Description

technical field [0001] The invention belongs to a kind of equipment using pyrolysis gasification technology to process waste organic matter such as domestic garbage and rural straw, and particularly relates to a combined pyrolysis gasification furnace. Background technique [0002] With the acceleration of urbanization and the development of agriculture, the output of waste such as urban household garbage and rural straw is increasing, which seriously affects the ecological environment of cities and villages. Large cities adopt the method of domestic waste incineration for power generation, which makes the advantages of domestic waste reduction and resource utilization very prominent, but the domestic waste in small cities and towns has become a difficulty in urban domestic waste management in my country due to the small amount and relatively scattered reasons. And the point is that the current treatment method is changing from landfill to comprehensive treatment. Although t...

Problems solved by technology

The sorted combustible garbage or direct incineration treatment method can solve the problem of a large amount of combustible garbage or straw, but it causes negative effects such as increased nitrogen oxides in the atmosphere, aggravated greenhouse effect, and "dioxin" emissions.
