NOVELTY - Device comprises a carbonization kiln, a draft fan, purifying and recycling device, and a tail gas processing device. The carbonizing kiln adopts pool type structure. The bottom of pool-type carbonization kiln is set with an air passage. The air passage is connected at the bottom of sidewall of the carbonization kiln exhaust port. The outside of the carbonization kiln exhaust port is set with a filtering and purifying tanks. The filtering and purifying tank is filled with filtering and purifying raw material. The filtering and purifying tank is connected with purifying and recycling device.    USE - The device is useful for producing carbon, gas, oil, and heat and power by using various biomass raw materials.    ADVANTAGE - The device expands the utilization range of biomass raw materials, shortens the production period and improves the yield and quality.    DETAILED DESCRIPTION - Device comprises a carbonization kiln, a draft fan, purifying and recycling device, and a tail gas processing device. The carbonizing kiln adopts pool type structure. The bottom of the pool-type carbonization kiln is set with an air passage. The air passage is connected at the bottom of the sidewall of the carbonization kiln exhaust port. The outside of the carbonization kiln exhaust port is independently set with a filtering and purifying tanks. The filtering and purifying tank is filled with filtering and purifying raw material. The filtering and purifying tank is connected with purifying and recycling device. The air outlet of the purifying and recycling device is connected to a draft fan through a pipeline. The draft fan air outlet is connected to a gas separator. The gas phase separator is directly connected to light structure of tail gas processing device. The upper part of the gas separator is equipped with an explosion-proof device.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the device for producing carbon, gas, oil, and heat and power by using various biomass raw materials.
