Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

As shown in Figures 1 and 2, the utility model is a biomass generator tar separator, which includes an outer cylinder 4, and the outer cylinder 4 accepts the gas produced by the biomass gasification furnace through the outer cylinder air inlet 8 provided on the side wall. Oil-gas mixture, the air inlet 8 of the outer cylinder is connected with the outer cylinder 4 along the tangential direction of the cross section of the outer cylinder 4 . It also includes an inner cylinder 3 located inside the outer cylinder 4 and coaxial with the outer cylinder 4. The inner cylinder 3 communicates with the outer cylinder 4 only through the inner cylinder air intake pipe 5 arranged on the side wall of the inner cylinder 3. The inner cylinder air intake pipe The length of 5 ensures that it can be stretched into the inner cylinder 3. A bottom surface of the inner cylinder 3 is provided with an air outlet pipe 1 communicating with the outside of the outer cylinder 4, and the length of the air outlet pipe 1 ensures that it can be stretched into the inner cylinder 3; the other end of the inner cylinder 3 is tapered, and the bottom of the cone A connecting cylinder 6 is provided, and the connecting cylinder 6 is connected to a liquid outlet 7 , and the liquid outlet 7 leads to the outside of the outer cylinder 4 . Inside the outer cylinder 4, the connecting cylinder 6 communicates with the outer cylinder 4 through the communication hole 10 thereon to ensure that the separated tar and water vapor can flow out well. Similarly, the outer cylinder 4 is tapered at this end.

Wherein, a partition 2 is also arranged in the inner cylinder 3, the number of the partitions 2 is arbitrary, and a plurality of ventilation holes 9 are arranged on it, and when there is one partition 2, it divides the inner cylinder 3 into two parts, Inner barrel air intake pipe 5 and air outlet pipe 1 are respectively located on both sides of the dividing plate 2. When there are multiple dividing plates 2, they are arranged in parallel to form a dividing plate group, and the inner cylinder inlet pipe 5 and air outlet pipe 1 are respectively located on both sides of the dividing plate group.

As shown in FIG. 3 , it is a schematic diagram of the structure of the partition plate 2 , which is consistent with the shape of the longitudinal section of the inner cylinder 3 , and a plurality of ventilation holes 9 are arranged on the plate.

The mode of work of the present utility model is:

The oil-vapor mixture produced by the biomass gasification furnace enters the outer cylinder 4 from the air inlet 8 of the outer cylinder, and enters along the tangential direction of the outer cylinder 4 when entering, forming a certain cyclone effect. During the cyclone process, the tar and water vapor Under centrifugal action, it is thrown onto the inner wall of the outer cylinder 4, along the inner wall, flows to the bottom under the action of gravity to collect liquid, forming a gas-liquid separation; the rest of the mixture enters the inner cylinder 3 from the inlet pipe 5 of the inner cylinder, Since the entry has a certain speed, it directly impacts on the partition 2, the liquid is further separated, and flows down along the inner wall of the inner cylinder 3, while the gas flows into the other part of the inner cylinder 3 through the vent hole 9 on the partition 2, Finally, it is discharged from the outlet pipe 1. According to the volume of the tar separator, multiple partitions can be set to achieve a good gas-liquid separation effect. However, in order not to increase the flow resistance of the gas, the number of vent holes 9 provided on the partition 2 and the final overall flow area should be properly configured.

The air outlet pipe 1 and the inner cylinder air inlet pipe 5 must have a certain length and extend into the cylinder body of the inner cylinder 3 to ensure that when the gas enters, the liquid bonded to the side wall does not flow into the next chamber through the pipe In the room, or discharged into the clean gas pipeline, the inner cylinder inlet pipe 5 is located in the middle or below the middle of the side wall of the inner cylinder 3, which is more conducive to separation.
