Detailed Description

As shown in fig. 1, a tar recycling apparatus of a biomass gasification furnace includes a tar recycling tank 10. The tar settling pipe is inserted into the tar recovery box 10 and is connected with the gasifier ejector. Tar recovery tank 10 water is provided in the tar recovery tank 10. The tar in the fuel gas is guided into the tar recovery box 10 through a tar settling pipe. The tar recovery box 10 is connected with the dilution box 11 through a conveying pipe 2, one end of the conveying pipe 2 is installed at the bottom of the tar recovery box 10, and the other end of the conveying pipe is installed at the top of the dilution box 11. The conveying pipe 2 is provided with a first electromagnetic valve 1; when the tar recovery tank 10 reaches a certain liquid level, the first electromagnetic valve 1 is opened, and tar and water are conveyed to the dilution tank 11 through the conveying pipe 2. Dilute 11 inner walls of case and set up heating device 5, dilute 11 top surfaces of case middle part and set up agitator motor 3, agitator motor 3 passes through stirring rod 4 and connects stirring vane 6. And starting the heating device 5 to heat and dilute, starting the stirring motor to stir, and improving the dilution efficiency. The bottom of the dilution box 11 is provided with a delivery pipe 7, and the delivery pipe 7 is provided with a second electromagnetic valve 12. The conveying pipe 7 is connected with a tar pump 8; the tar pump 8 is connected with the pipeline 9, the pipeline 9 is connected with the nozzle 14, and the nozzle 14 is arranged on the top surface of the carbonization combustion zone 13. After dilution, the second electromagnetic valve 12 is opened, the diluted tar is conveyed to the carbonization and combustion zone 13 by the tar pump 8, and in the carbonization and combustion zone 13, the diluted tar is adsorbed by charcoal, and is subjected to secondary combustion at high temperature under the high-temperature condition of the gasification furnace to be decomposed into combustible gas.

The heating device 5 is an electric heating plate or steam heating, and heating is convenient.
