USE - Biomass dry distillation tower.    DETAILED DESCRIPTION - A biomass dry distillation tower comprises a box body connected with a supporting foot (69) at the bottom. The box body includes a dry distillation tower right box plate (20), a dry distillation tower front box plate (21), a dry distillation tower left box plate (26), a dry distillation tower rear box plate (44), a dry distillation tower top box plate (37), and a dry distillation tower lower square tapered hopper (7). The dry distillation tower top box plate is communicated with a front gas outlet and a rear gas outlet which both are communicated. The dry distillation tower front box plate is provided with a dry distillation box temperature sensor. The dry distillation tower right box plate is provided with a dry distillation chamber pressure sensor. Groups of triangular heat exchange boxes are centrally penetrated at the box body and respectively penetrated through the dry distillation tower right box plate and the dry distillation tower left box plate. Each triangular heat exchange box is internally provided with a combustor gas supply branch pipe communicated with a gas supply vertical pipe at the top. The gas supply vertical pipe is communicated with a gas supply branch pipe whose one end is communicated with a gas supply main pipe communicated with a gas supply fan. The gas supply fan is welded on the dry distillation tower right box plate via a cross support of the gas supply fan and includes a support. The right sealing plate of the triangular heat exchanger is provided with a pulse igniter sleeve at the upper part. The pulse igniter sleeve is provided with a flange outside. The flange is fixedly provided with a blind plate via a bolt. The blind plate is centrally assembled with a pulse igniter provided with a wiring shaft at outer exposed head. The left sealing plate of the triangular heat exchanger is provided with a smoke discharging pipe of the heat exchanger at upper part. One end of the smoke discharging pipe is communicated with a chimney welded with a chimney bottom sealing plate at the bottom end. The dry distillation tower right box plate is communicated with a blowing main pipe and a combustor air supply main pipe. One other end of the blowing main pipe is communicated with a gas intruder machine whose outlet main pipe is communicated with blowing branch pipes. Air outlet holes of the blowing pipe are opened at bottom of blowing branch pipes. A sealing plate of the blowing branch pipes is welded at the end of branch pipes. The combustor air supply main pipe is communicated with a combustor air supply main valve whose other end is communicated with a combustor air supply branch pipe. A left water tank and a right water tank are respectively welded at both the left and right sides of the box body. Front and rear surfaces of the left water tank are respectively welded together with the dry distillation tower front box plate and the dry distillation tower rear box plate. Front and rear surfaces of the right water tank are respectively welded together with the dry distillation tower front box plate and the dry distillation tower rear box plate. Cooling water pipes are communicated between the left and right water tanks. A biomass carbon quality viewing opening provided with a biomass carbon temperature sensor at one side is located at both lower parts of the dry distillation tower front box plate and the dry distillation tower rear box plate. A feeding system is provided above the box body. The feeding system includes a primary feeding auger, a secondary feeding auger and a distributing box. A blanking box is connected at bottom of the dry distillation tower lower square tapered hopper and in internally assembled with a carbon discharging auger. A horizontal clapboard in the blanking box is opened with tar and wood vinegar flowing holes. The carbon discharging auger is crossly penetrated through the blanking box via the tar and wood vinegar flowing holes. A tar and wood vinegar outlet is provided at bottom of the blanking box. A biomass carbon outlet is opened downwards at tail part of the carbon discharging auger.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the biomass dry distillation tower.
