NOVELTY - Horizontal pushing vertical biomass carbon gas-oil-joint device comprises a dry distillation reaction space surrounded by an external and internal furnace lining (7). The dry distillation reaction space is divided into six layers of horizontal case space. The six layers from top to bottom are divided into a moisture removal region as a top layer, a low temperature pyrolysis zone as a middle layer, and a high temperature pyrolysis zone as a bottom layer. A horizontal furnace grate (2) is set on each layer of horizontal case space in multiple times pull back manner.    USE - Used as a horizontal pushing vertical biomass carbon gas-oil-joint device.    ADVANTAGE - The device reduces the power consumption of a draught fan, lowers the operating cost, occupies less space, and is vertically arranged and easy for parallel operation of multiple sets. The method achieves physical partition of the pyrolyzing process, improves the adjustability of the dry distillation process, rapidly separates pyrolysis products and the material layer, and produces high liquid product yield of the pyrolysis products.    DETAILED DESCRIPTION - Horizontal pushing vertical biomass carbon gas-oil-joint device comprises a dry distillation reaction space surrounded by an external and internal furnace lining (7). The dry distillation reaction space is divided into six layers of horizontal case space. The six layers from top to bottom are divided into three regions: a moisture removal region as a top layer, a low temperature pyrolysis zone as a middle layer, and a high temperature pyrolysis zone as a bottom layer. A horizontal furnace grate (2) is set on each layer of horizontal case space in multiple times pull back manner, where the material layer is horizontal furnace grate, which promotes stratification within the device from downwards movement. An INDEPENDENT CLAIM is also included for use method of the horizontal pushing vertical biomass carbon gas-oil-joint device, comprises dividing six spaces of the horizontal box body space into three zones from top to bottom containing moisture removal region as top two layers, low temperature pyrolysis zone as middle two layers and high temperature pyrolysis zone as bottom two layers, promoting stratifying using the horizontal furnace grate of the eccentric drive device from the downward movement of the material layer, introducing heat transfer medium under certain temperature and flow rate from above the heat transfer medium inlet (5) into each of the horizontal box body space to form the biomass raw material of the material layer through the horizontal box body space when the heat transfer medium passes between the material layer, forming biomass material in the material layer of the horizontal box body space, passing the thermal mass from the top through the material layer, passing the thermal mass and heat transfer between the biomass and then into the lower material layer, and conveying thermal mass and the biomass gas products from the horizontal cabinet space layer into the gas outlet, using different thermal mass load during convection in the horizontal box body space of the three different partitions of the dry distillation reaction space in the device, removing water area of the first and the second horizontal box body space and maintaining heat transfer as low temperature flue gas, maintaining heat transfer as medium low temperature flue gas in the third and the fourth horizontal box body space, and heat carrier medium as high temperature gas in the low temperature pyrolysis zone and in the fifth and the sixth horizontal box body space in the low temperature pyrolysis zone, moving the material layer of the furnace grate in a downward manner within the horizontal box body space, conveying into the sealing column when it enters at the end of the grate, conveying the biomass from the upper layer into the lower layer grate via the next layer feed tube of the sealing material column, simultaneously moving the biomass into the next level of the grate, completing the pyrolysis process after passing the biomass through the six layers, conveying the biomass pyrolytic coke from the lowermost grate into the coke quenching tank provided with combination of wet and dry coke quenching, discharging temperature-qualified biological charred coke into the discharging packing auger and hence completing the production flow.
