1. A standing coke-making furnace, comprising a carbonization segment and an activation segment in order from up to down, wherein within a furnace body, the standing coke-making furnace is provided with:
a plurality of feed paths, extending along a vertical direction and spaced in a horizontal direction, wherein
each feed path is interconnected between the carbonization segment and the activation segment,
each feed path has a first side wall and a second side wall opposite to the first side wall in the horizontal direction,
the first side wall is provided with a plurality of first gas orifices for the activation segment that are spaced from up to down, and
the second side wall is provided with a plurality of second gas orifices for the activation segment that are spaced from up to down,
wherein the plurality of first gas orifices and the plurality of second gas orifices in a same feed path are symmetrical one-to-one in the horizontal direction, and
wherein the plurality of first gas orifices and the plurality of second gas orifices respectively arranged at adjacent side walls of two feed paths are spaced in the vertical direction, and
a plurality of first gas flues and two second gas flues, wherein each first gas flue is defined by adjacent side walls of two feed paths, and each second gas flue is defined by an outer wall of an outermost feed path and an inner wall of the furnace body, wherein
the first gas flue and the second gas flue are each provided with a closed top and a closed bottom,
a layer of first sealing segments is arranged between the carbonization segment and the activation segment in both the first gas flue and the second gas flue,
a plurality of air supply ports are arranged in the first gas flue and the second gas flue for the activation segment, wherein the air supply port is arranged to be closely adjacent to the first gas orifice or the second gas orifice,
the second gas flue is provided with a first inlet for an activating gas and a first outlet for the activating gas in the activation segment,
a layer of second sealing segments is arranged for the activation segment in the plurality of first gas flues and one of the two second gas flues,
the second sealing segment arranged in the first gas flue is located in the vertical direction between the first gas orifice and the adjacent second gas orifice that are spaced at adjacent side walls of two feed paths, and
the layer of second sealing segments is located in the vertical direction between the first inlet and the first outlet,
wherein the activating gas enters the second gas flue from the first inlet; enters the outermost feed path through the second gas orifice to activate a carbonized material therein; enters the first gas flue through the first gas orifice, converges with air supplied from the air supply port and then travels upwards along the first gas flue; enters another feed path through the second gas orifice to activate the carbonized material therein; enters another one of the plurality of first gas flues through the first gas orifice, converges with air supplied from the air supply port and then travels downwards along the first gas flue; enters another one of the plurality of feed paths through the second gas orifice to activate the carbonized material therein; continues as such to travel forward and finally discharges from the first outlet, thereby allowing the activating gas to travel in a substantial U-shaped path below and above the layer of second sealing segments.
