DETAILED DESCRIPTION - An integrated dry-wet biomass fuel gas fractional condensation oil gas separating device comprises a main tube (1), a fuel gas pipe (2), and condensing chamber (3) which is connected with a temperature sensor (5). The main tube of the top beam is connected with the upper end enclosure (15). The upper end enclosure is provided with upper gas outlet (151). The main tube at the bottom of the lower sealing plate is connected with lower end enclosure (17). The lower end enclosure is provided with a gas inlet (171). The main tube is provided with a multi-parallel of gas pipe, the fuel gas pipe top end of the upper sealing plate and the upper rear end enclosure, the bottom end of gas pipe through the lower sealing plate and the lower rear end enclosure. The fuel gas pipe of the outer wall of the main tube of the inner wall of the forming a condensing cavity and the main tube of the upper wall is provided with a connected with the gas of the temperature sensor. The main tube comprises upper tube (11) in tube (13) and the lower tube (12). The upper end enclosure is upper plate, upper tube in tube, lower tube, and close board. The lower rear end enclosure is connected with the upper tube. The lower tube is provided with a corresponding upper pipe (21) and the lower pipe (22). The upper pipe and lower pipe are connected to the fuel gas pipe. The upper pipe of the outer wall of the upper tube of the inner wall of the form with upper cavity (31) and the lower pipe of the outer wall and the lower tube of the inner wall of the forming with a lower cavity (32). The upper cavity of the top part is provided with upper condensing port (34). The upper cavity of the bottom of the main tube is connected with the pipe of the outer part (33). The lower cavity of the top part is connected with the lower cavity which is set at the bottom of the condensing port (35). The upper cavity and the lower cavity is formed the condensing chamber in a tube comprises an inclined cavity plate are parallel to each other and of upper cavity plate, or plate. The lower cavity plate in the tube is connected with the inner wall of the tube in near upper cavity upper plate in tube of the inclined cavity plate at the joint of the top end is connected in tube close to the lower wall of the upper cavity plate in tube of the inclined cavity plate at the joint of bottom end is connected with the inclined cavity board in part of is provided with a multi-cone of the air platform. The conical air platform comprises a side part and is parallel to each other of table top, a bottom, a top part in the bottom, a top part, and a bottom are sealing structure. The side part and upper cavity plate is provided with a side of the air inlet. The side part and the upper side air inlet is provided with a side of the air outlet, and the upper pipe by the upper cavity plate, a side air outlet, a side air inlet, an inclined cavity plate, the lower cavity plate and the rear lower pipe. The inclined cavity plate, plate and in tube is surrounded by the upper set of oil outlet is connected with the upper oil collecting tube. The lower end enclosure bottom part is set up of the lower oil port and the lower oil tube.
