AI Technical Summary
In existing tar recovery equipment, when the gas comes into contact with the plate-like structure in the reactor, the increase in the gas temperature leads to a decrease in the tar condensation effect, resulting in the discharged gas still containing tar.
A tar recovery device is designed, using components such as kettle body, input tube, heat dissipation gate, arc plate and smoke exhaust pipe. The gas condenses tar through the surface of the arc plate, and the temperature is transferred through the heat dissipation gate to keep the arc plate temperature within a suitable range to ensure the effective recovery of tar.
Through this device, the tar in the gas can be effectively condensed and recovered, avoiding the problem of still containing tar when the gas is discharged, and improving the efficiency and effect of tar recovery.
