Embodiment Construction
[0025] Below in conjunction with accompanying drawing, the present invention will be further described.
[0026] by Figure 1-3 The 10 gas injection channels 3 are shown in the explanatory diagram, thereby illustrating the gas injection method. A top cover 13 is arranged above the fixed bed body, and the two are connected through matching upper and lower screw ports 12 , 9 , and sealed by a flange sealing ring 10 at the same time. After the multi-component atmospheric gas enters the annular passage 2 from the air inlet 1, it enters the ten gas injection passages 3 uniformly through the retaining ring 11 respectively. According to engineering experience and device load conditions, unattended control and intelligent operation of distribution valves can be realized by setting corresponding programs. The gas in the gas injection channel 3 passes the heat of the heating wall 8 transferred by the heat conducting clip 15, and enters the pyrolysis material 5 through the gas injectio...
