Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

The utility model provides a pyrolysis oven built on stilts structure, includes pyrolysis oven combustion chamber 1, 1 bottom of pyrolysis oven combustion chamber is equipped with grate 2, built on stilts 3 be located the inner wall lower part of pyrolysis oven combustion chamber 1 to be located the top of grate 2.

Generally, when the waste pyrolysis is performed, the waste is uniformly spread in the combustion chamber of the pyrolysis furnace, the waste located at the inner wall of the combustion chamber 1 of the pyrolysis furnace is at the edge, so that the air content of the contact is less, the combustion of the waste at the part is insufficient, and the combustion speed is slow, so that when the pyrolysis is performed, the combustion speed of the waste located at the middle part of the combustion chamber 1 of the pyrolysis furnace is faster than that of the waste located at the inner wall of the combustion chamber 1 of the pyrolysis furnace, so that the combustion is not uniform, the quality of the waste pyrolysis is reduced, and therefore, the air content of the waste contact located at the inner wall of the combustion chamber 1 of the pyrolysis furnace is increased by designing the overhead layer 3.

The overhead layer 3 include a plurality of overhead pieces 301, a plurality of overhead pieces 301 all set up on the inner wall of pyrolysis furnace combustion chamber 1 and towards the central protruding setting of pyrolysis furnace combustion chamber 1, a plurality of overhead pieces 301 set up around pyrolysis furnace combustion chamber 1 inner wall equidistance interval, form the air duct 302 on the vertical direction between two adjacent overhead pieces 301.

When the waste is initially filled, the waste is uniformly paved upwards on the grate 2 to fill the combustion chamber 1 of the pyrolysis furnace, that is, initially, the space between the overhead layer 3 and the grate 2 and the air channel 302 are filled with the waste, when the waste starts to burn and pyrolyze, the waste starts to burn upwards from the grate 2, coke is formed at the beginning, the coke continues to burn and becomes ash to fall into an ash tray, along with the combustion time, the coke layer gradually moves upwards, when the coke layer moves to the upper part of the overhead layer 3, the waste below the overhead layer 3 gradually burns into ash to fall into the ash tray, that is, after a period of combustion, the waste filled in the air channel 302 and the waste below the overhead block 301 are all burnt completely, and the coke is a massive condensate with a size larger than that of the air channel 302, therefore, the coke is erected above the combustion chamber and cannot fall into the air channel 302, therefore, enough space is left by the overhead block 301 in the lower part of the area, and the waste in the air channel 302 is burnt out to dredge the air channel 302, so that the lower part of the waste at the inner wall of the combustion chamber 1 of the pyrolysis furnace is filled with a large amount of air for the waste to be burnt.

The upper surface 3011 of the block is inclined downward from the inner wall of the combustion chamber 1 of the pyrolysis furnace toward the center of the combustion chamber 1 of the pyrolysis furnace. Ash accumulated on the overhead block upper surface 3011 can slide down along the inclined upper surface of the overhead block 301.

The lower surface 3012 of the overhead block is inclined upward, and the inner wall of the combustion chamber 1 of the pyrolysis furnace is inclined upward toward the center of the combustion chamber 1 of the pyrolysis furnace. The air under the overhead block 301 may be diffused upward along the inclined lower surface.

The inclined length of the overhead block upper surface 3011 is longer than the inclined length of the overhead block lower surface 3012.
