DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0022] like Figures 1 to 2As shown, a production equipment for extracting bamboo vinegar comprises a carbonization furnace 1, a gas delivery fan 2 is provided at the air outlet of the carbonization furnace 1, a labyrinth separator 3 is provided at the air outlet position of the gas delivery fan 2, the labyrinth separator 3 is connected to a wood vinegar extraction device 4, the labyrinth separator 3 comprises a separation cylinder 301, a separation cavity 304 is provided in the separation cylinder 301, a purification pipe 305 is provided in the middle of the separation cavity 304, a gas outlet 306 is provided on the side of the purification pipe 305, a gas inlet 303 is provided in the separation cylinder 301, and the gas inlet 303 corresponds to the air outlet position of the gas delivery fan 2. The gas inlet 303, the separation cavity 304, the purification pipe 305, the gas outlet 306 are provided on the side of the purification pipe 305, and the separation cylinder 301 is provided with a gas inlet 303. The gas inlet 303 corresponds to the air outlet position of the gas delivery fan 2. The gas inlet 303, the separation cavity 304, the purification pipe 305, the gas outlet 306, the gas outlet 306, the gas inlet 303, the separation cavity 304, the purification pipe 305 ... The gas outlet 306 and the air inlet of the wood vinegar extraction device 4 are connected. This technical process uses bamboo as raw material. The bamboo burns in the carbonization furnace 1 and produces biomass gas. After the biomass gas is discharged from the gas outlet of the carbonization furnace 1, it is transported in an inclined direction through the gas conveying fan 2, so that the biomass gas enters the separation cylinder 301 from the gas inlet 303 in a tangential manner, and uses the centrifugal force generated by the rotating airflow to achieve gas-solid separation, and then enters the purification pipe 305 to achieve secondary purification and separation, and finally is discharged from the gas outlet 306. The purification efficiency is high, convenient and fast, and will not affect other condensable components in the biomass gas, thereby preventing blockage of the conveying pipeline and corrosion of heat-using equipment.

[0023] Specifically, a heating jacket 3011 is provided on the inner wall of the separation cylinder 301, a steam inlet 3012 is provided at the bottom end of one side of the heating jacket 3011, and a steam outlet 3013 is provided at the top end of the other side of the heating jacket 3011. The steam inlet 3012, the heating jacket 3011 and the steam outlet 3013 are connected. Hot steam enters the heating jacket 3011 from the steam inlet 3012, so that the interior of the heating jacket 3011 is filled with hot steam, and finally is discharged from the steam outlet 3013. This design can transfer the heat of the heating jacket 3011 to the separation chamber 304, thereby ensuring that the condensable components in the biomass gas will not condense.

[0024] The lower end of the separation cylinder 301 extends inwardly to form a cone hopper 302. A water cooling jacket 3021 is provided on the inner wall of the cone hopper 302. A cold water inlet 3022 is provided at the bottom end of one side of the water cooling jacket 3021, and a cold water outlet 3023 is provided at the top end of the other side of the water cooling jacket 3021. The cold water inlet 3022, the water cooling jacket 3021 and the cold water outlet 3023 are connected. Cold water enters the water cooling jacket 3021 from the cold water inlet 3022 and is finally discharged from the cold water outlet 3023, thereby cooling the solid particles falling into the cone hopper 302.

[0025] From Figure 2 It can be seen that there is a gap between the heating jacket 3011 and the water cooling jacket 3021, so the two are independent of each other and do not interfere with each other, so that the hot steam and cold water will not mix with each other.

[0026] The purification pipe 305 is hollow and contains a separation material 3051. The separation material 3051 is either a ceramic Raschig ring or porous ceramsite. Both the ceramic Raschig ring and the porous ceramsite have absorption capacity and can further separate fine particles in the biomass gas.

[0027] The carbonization furnace 1 further includes a belt hopper 5, which is provided with a conveyor belt 6. The output port of the conveyor belt 6 corresponds to the feed port of the carbonization furnace 1. The wood vinegar extraction device 4 includes a first wood vinegar extraction component 401 and a second wood vinegar extraction component 402. The bottom of the first wood vinegar extraction component 401 and the second wood vinegar extraction component 402 are both provided with a aging component 403. The aging component 403 is connected to a delivery pump 404, and the delivery pump 404 is connected to a wood vinegar storage tank 405. The exhaust ports of the first wood vinegar extraction component 401 and the second wood vinegar extraction component 402 are correspondingly provided with a blower 7, and the blower 7 is correspondingly provided with an expansion device 8.

[0028] An opening and closing valve 3024 is provided at the bottom of the cone hopper 302. The opening and closing valve 3024 and the discharge port of the carbonization furnace 1 are connected to a cooling and packaging device 9. The bamboo charcoal coming out of the bottom of the carbonization furnace 1 and the solid particles separated by the labyrinth separator 3 enter the cooling and packaging device 9 for mixing and are collected as bamboo charcoal products.

[0029] Working principle: The biomass raw material is transported to the belt silo 5 and transported into the carbonization furnace 1 through the conveyor belt 6. The biomass gas is cracked under certain temperature conditions in the carbonization furnace 1 to produce the gas. The biomass gas is transported to the labyrinth separator 3 along the tangential direction through the gas conveying fan 2, thereby separating the solid particles in the gas. The gas processed by the labyrinth separator 3 enters the first wood vinegar extraction component 401 and the second wood vinegar extraction component 402 respectively. After condensation and separation, all the wood vinegar components in the gas are extracted. The extracted wood vinegar is matured in the maturation component 403 to improve the quality and purity of the wood vinegar and remove unnecessary impurities, thereby obtaining a higher purity and more stable wood vinegar crude liquid. After the maturation is completed, it is transported to the wood vinegar storage tank 405 for storage through the delivery pump 404. The gas after the wood vinegar is extracted is clean gas. It enters the expansion device 8 through the blower 7 to further remove the small droplets carried, and can directly enter the pipeline for long-distance transportation or directly enter the thermal equipment 10 for use.

[0030] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
