Embodiment 1
[0030] This embodiment provides a biomass pyrolysis gas spraying device, including a spraying tank 1, see the structure figure 1 ,Specifically,
[0031] The baffle plate 5 is connected with the top of the spray tank body, and the spray tank body is divided into two spray areas, which are respectively the first spray area 9 and the second spray area 10, and the first spray area 9 and the second spray area. The spray areas 10 are communicated with each other. In other embodiments, the baffle can also divide the spray tank into several spray areas, and the baffle is also connected to the bottom of the spray tank;
[0032] The first spray area is provided with an air inlet 2 and a first spray port 4-1, the air inlet is arranged above the first spray port, and in the first spray area, the pyrolysis gas and the spray liquid flow together In other embodiments, the air inlet can be set under the spray port, and the pyrolysis gas can also be in countercurrent contact with the spray li...

The invention belongs to the technical field of oil-gas separation and particularly relates to a biomass pyrolysis gas spraying device and a separating method. The provided biomass pyrolysis gas spraying device comprises a spraying tank body, the spraying tank body is internally provided with an isolating structure to divide the spraying tank body into at least two spraying areas, and the sprayingareas are communicated; each spraying area comprises at least one spraying opening for spraying out a spraying liquid; the flowing directions of the pyrolysis gases in the at least two spraying areasare opposite, and the flowing directions of the pyrolysis gases in the at least two spraying areas in the device are opposite, so that a biomass oil and a mechanical impurity in the pyrolysis gas arethoroughly separated from the gas, the purity of the exhausted noncondensable gas is increased, no pipeline is connected among the various components of the spraying device, and the problems that thepipeline is bonded with the precipitation of the biomass oil, the inner diameter of the device is gradually reduced, or even the device is blocked are solved.
Description
technical field [0001] The invention belongs to the technical field of oil and gas separation, and in particular relates to a biomass pyrolysis gas spraying device and a separation method. Background technique [0002] Biomass carbonization technology is based on pyrolysis technology, which uses thermal energy to cut off chemical bonds in macromolecules and convert biomass into solid, liquid and gas products under the condition of isolation of air or a small amount of air. The products of biomass carbonization can be applied in many fields, effectively improving the comprehensive utilization efficiency of biomass. The solid product is biochar, which can be applied to soil improvement and carbon sequestration; the gas product is biomass gas, the main component of which is H 2 , CO, CH 4 、C 2 h 4 , CO 2 etc., can be used as clean energy; liquid products are biomass oil and wood vinegar, wood vinegar can be used as a plant growth regulator, can promote the growth of vegetab...
