Ground groove type double-channel garbage pyrolysis combustion device and garbage pyrolysis combustion method

Abstract

The invention discloses a ground groove type double-channel garbage pyrolysis combustion device and a garbage pyrolysis combustion method. The ground groove type double-channel garbage pyrolysis combustion device comprises a first furnace body and a second furnace body which are buried in a ground groove, and a third furnace body is arranged between the first furnace body and the second furnace body. The first furnace body is used for conducting low-temperature pyrolysis, and a first pushing device used for pushing bottom materials to the lower portion of the third furnace body is arranged atthe bottom of the first furnace body. The second furnace body is sequentially provided with a material storage chamber, a secondary combustion chamber and a grate combustion chamber from top to bottom. The material storage chamber is provided with a second pushing device used for pushing the materials to the upper portion of the third furnace body. A third pushing device used for pushing the materials to the grate combustion chamber is arranged at the bottom of the third furnace body. The grate combustion chamber communicates with the secondary combustion chamber in sequence. By means of the ground groove type double-channel garbage pyrolysis combustion device and the garbage pyrolysis combustion method, the garbage pyrolysis treatment capacity can be increased, in addition, the heat energy utilization rate can be effectively increased, and the labor cost is reduced.

Description

technical field [0001] The invention relates to a trough-type dual-channel garbage pyrolysis combustion device and a pyrolysis combustion method thereof, belonging to the technical field of garbage environmental protection treatment. Background technique [0002] Garbage is a renewable resource. If it can be effectively integrated and utilized, it can create huge economic benefits. Although the current landfill method can dispose of garbage, there are problems such as consuming land resources and polluting soil and water bodies. Another common treatment method is incineration. However, due to the common problems of high humidity and complex components of garbage, the general incineration treatment method is not only difficult to burn completely, but also easily produces toxic and harmful gases (dust, sulfur, nitrate pollutants, dioxins, etc.), and in order to make the garbage To ignite, fuel needs to be added, resulting in additional energy consumption and the generation o...

Problems solved by technology

[0003] However, in the current garbage pyrolysis furnaces, it is common to cause insufficient pyrolysis due to too much heat and accumulation in the furnace, so that the garbage treatment capacity cannot be high. Therefore, it is necessary to mechanically pyrolyze the garbage in batches. A large number of manual servos, and frequent feeding of furnaces can easily cause heat loss
