Description

Technical Field

[0001] The invention relates to the technical field of liquor fermentation, and in particular to an alcohol fermentation device and a waste gas treatment device for small-molecule liquor fermentation. Background Art

[0002] Small molecule liquor has attracted attention in recent years because its small molecule components, such as small molecule peptides and small molecule organic acids, are believed to have unique health benefits and taste characteristics. The fermentation process is the core link in the production of small molecule liquor. Unlike traditional liquor fermentation, small molecule liquor fermentation requires specific microbial communities and fermentation conditions to promote the production of small molecules. The saccharified raw materials are placed in a fermentation tank, and an appropriate amount of water is added. After stirring evenly, the fermentation is sealed. During the fermentation process of liquor, the sugar in the raw materials is decomposed by yeast, and a large amount of carbon dioxide waste gas will be generated and accumulated in the fermentation tank. These carbon dioxide will gradually escape from the mash and become the main component of fermentation waste gas. If these waste gases are discharged directly, it will pollute the atmospheric environment and have a negative impact on air quality and the ecological environment.

[0003] When existing waste gas treatment devices treat waste gas generated by liquor fermentation, most of them treat the waste gas by directly spraying spray liquid into the waste gas. Direct spraying is prone to local over-spraying. The area near the nozzle usually receives more spray liquid, which may cause the waste gas in this area to be over-treated, while the area far away from the nozzle may not get enough spray liquid, and the waste gas is not fully treated. This uneven spraying will make the effect of the entire waste gas treatment process inconsistent, and it is difficult to achieve a stable treatment standard. At the same time, direct spraying makes it easy for droplets formed by the spray liquid to be entrained by the waste gas. The entrainment of droplets causes the spray liquid to fail to fully play its role in the treatment device, reducing the effective contact time and contact area between the waste gas and the spray liquid, so that the pollutants in the waste gas do not have enough time to react with the spray liquid and are discharged, thereby affecting the efficiency and quality of waste gas treatment.

The saccharified raw materials are put into the fermentation tank 11, and a proper amount of water is added, and the raw materials are stirred for sealed fermentation. The motor 121 is started to drive the turntable 122 to rotate, and the turntable 122 drives the support rod 123 to rotate, and the support rod 123 drives the rack through the connecting rod 124. 125 reciprocates, and the rack 125 is meshed with the gear 126 for transmission.

The gear 126 rotates to drive the stirring rod 111 to rotate forward and reverse, and the stirring rod 111 drives the No. 1 stirring blade 112 and the No. 2 stirring blade 113 to rotate. Since the No. 1 stirring blade 112 and the No. 2 stirring blade 113 are of different models, the No. 1 stirring blade 112 is used to stir the raw materials inside the fermentation tank 11 and diffuse the raw materials radially, and the No. 2 stirring blade 113 is used to push the raw materials at the bottom upward, so that the stirring effect of the raw materials is better.

[0040] See also Figure 5As shown, the installation box 12 includes a gear 126 arranged inside the installation box 12, and two limit blocks 127 are fixedly connected to the inner sides of the installation box 12, and the limit blocks 127 are arranged on the upper and lower sides of the gear 126. The gear 126 is supported by the limit blocks 127, and the gear 126 is also limited to ensure the stability of the gear 126. The inner thread of the gear 126 is connected with a screw rod 128, the upper end of the screw rod 128 passes through the upper end of the installation box 12, and the lower end of the screw rod 128 extends to the interior of the fermentation tank 11 and is fixed to the upper end of the stirring rod 111. When the raw materials in the fermentation tank 11 are stirred, since the screw rod 128 at the upper end of the stirring rod 111 is threadedly connected with the gear 126, the screw rod 128 is driven to move up and down, so that the screw rod 128 is used to drive the stirring rod 111 to rotate and move up and down at the same time, so as to fully stir the raw materials in the fermentation tank 11, so that the raw materials are mixed evenly, and it is ensured that the koji is evenly distributed in the raw materials. The koji contains rich microorganisms such as yeast, mold and enzymes. The uniform distribution is conducive to the smooth progress of the subsequent saccharification and fermentation process, thereby increasing the alcohol yield.

[0041] See also Figure 6As shown, during the fermentation process of white wine, the sugar in the raw materials is decomposed by yeast, and a large amount of carbon dioxide waste gas will be generated and accumulated in the fermentation tank 11. The carbon dioxide will gradually escape from the mash and become the main component of the fermentation waste gas. The outside of the support rod 123 is rotatably connected to a No. 1 rotating rod 132, and the other end of the No. 1 rotating rod 132 is rotatably connected to a No. 2 rotating rod 133. A fixed rod 131 is fixedly connected to one side of the mounting seat, and a No. 2 rotating rod 133 is rotatably connected to the fixed rod 131. One end of the No. 2 rotating rod 133 is rotatably connected to one end of the No. 1 rotating rod 132, and the upper end of the piston rod 134 is rotatably connected to one end of the No. 2 rotating rod 133. The piston cylinder 13 includes a piston rod 134 slidably connected to the inside of the piston cylinder 13, and the upper end of the piston rod 134 passes through the piston cylinder 13 and the upper end of the fermentation tank 11, the lower end of the piston rod 134 is in contact with the inner wall of the piston cylinder 13, and the outer wall of the piston rod 134 is provided with a sealing ring. During the stirring process, the turntable The rotation of the first rotating rod 132 drives the first rotating rod 132 to rotate, and the first rotating rod 132 drives the second rotating rod 133 to swing back and forth. The swinging second rotating rod 133 drives the piston rod 134 to move. The movement of the piston rod 134 is used to suck away the exhaust gas inside the fermentation tank 11. The lower end of the piston rod 134 is fixedly connected to the inner wall of the piston cylinder 13 with a return spring 135, and the return spring 135 is sleeved on the piston rod 134. The lower end of the piston cylinder 13 is provided with a through hole, and one end of the piston cylinder 13 is fixedly connected to the inner wall of the piston cylinder 13. It is connected to a connecting air pipe 136, the other end of which passes through the interior of the piston cylinder 13 and the fermentation tank 11 and extends to the interior of the recovery tank 21. When the No. 2 rotating rod 133 drives the piston rod 134 to move upward, the piston rod 134 moves and squeezes the return spring 135. At this time, the air pressure below the interior of the piston cylinder 13 is reduced. Under the action of the pressure difference, the exhaust gas inside the fermentation tank 11 is sucked into the interior of the piston cylinder 13 and transported to the interior of the recovery tank 21 through the connecting air pipe 136.

[0042] See also Figure 3 and Figure 7 As shown, the second purpose of this embodiment is to provide a waste gas treatment device for treating waste gas from an alcohol fermentation device for fermenting small molecule liquor, comprising a recovery device 2, the recovery device 2 comprising a recovery tank 21 and an air intake pipe 22 fixedly connected to the inside of the recovery tank 21, and three groups of annular blocks 23 rotatably connected to the inside of the recovery tank 21;

[0043] See also Figure 7 and Figure 8As shown, the intake pipe 22 includes a movable plate 221 mounted on the upper end of the intake pipe 22, a ball is fixed at the lower end of the support plate 211, the diameter of the ball is adapted to the inner diameter of the intake pipe 22, the lower end of the intake pipe 22 is connected to the connecting air pipe 136, the upper side of the movable plate 221 is fixedly connected to two cylindrical rods, the two cylindrical rods are slidably connected to the inside of the support plate 211, the upper side of the movable plate 221 and the lower side of the support plate 211 are fixedly connected to a compression spring 222, and the compression spring 222 is sleeved on the cylindrical rod, and the exhaust gas is discharged to the exhaust pipe 136 through the connecting air pipe 136. The exhaust gas is transported inside the recovery tank 21 and enters the interior of the intake pipe 22. The gas pushes the movable plate 221 upward, causing the movable plate 221 to move upward and squeeze the compression spring 222, so that the exhaust gas flows from the gap between the upper end of the intake pipe 22 and the lower end of the movable plate 221 to the interior of the recovery tank 21. The movable plate 221 can effectively prevent the exhaust gas from leaking, and at the same time, the exhaust gas inside the intake pipe 22 can only flow in one direction, so that the exhaust gas inside the intake pipe 22 cannot flow back, thereby avoiding the phenomenon of exhaust gas backflow and improving the recovery rate of the exhaust gas.

[0044] See also Figure 7 and Fig. 9 As shown, the recovery tank 21 includes a support plate 211 fixedly connected to the inside of the recovery tank 21, a spray liquid inlet pipe 214 is fixedly connected to the upper side of the support plate 211, and the upper end of the spray liquid inlet pipe 214 passes through the upper end of the recovery tank 21, and a shunt pipe 232 is arranged inside the side plate 233, and the two ends of the shunt pipe 232 are respectively connected to the spray liquid inlet pipe 214 and the annular block 23, and the outer wall array of the annular block 23 is provided with a nozzle 234, which transports the spray liquid into the recovery tank 21 through the spray liquid inlet pipe 214, and the spray liquid flows from the spray liquid inlet pipe 214 to the shunt pipe 232, and reaches the annular block 23 and is sprayed from the nozzle 234. During the spraying process, when the particulate matter in the exhaust gas is mixed with When the droplets collide, due to the adhesion of the droplets, the particulate matter will be wrapped in the droplets to form larger particles. These particles settle from the exhaust gas under the action of gravity, thereby achieving the purpose of removing the particulate matter. At the same time, the nozzle 234 sprays the spray liquid onto the inner wall of the recovery tank 21, so that the spray liquid can be distributed more evenly on the inner wall of the recovery tank 21. The liquid will flow along the inner wall under the action of gravity and form a liquid film. The exhaust gas needs to pass through the liquid film area when flowing inside the recovery tank 21, which prolongs the contact time between the exhaust gas and the spray liquid, and will fully contact the liquid film on the inner wall. Compared with directly spraying into the exhaust gas, this method can greatly increase the contact area between the exhaust gas and the spray liquid.

[0045] See also Figure 7 and Fig. 9As shown, the upper side of the support plate 211 is slidably connected to the No. 1 moving rod 212, the upper end of the No. 1 moving rod 212 passes through the upper end of the recovery tank 21 and is rotatably connected to the end of the No. 2 rotating rod 133 away from the piston rod 134. When the No. 2 rotating rod 133 reciprocates, when the No. 2 rotating rod 133 drives the piston rod 134 to move upward, at this time, the other end of the No. 2 rotating rod 133 drives the No. 1 moving rod 212 to move downward, and the No. 1 moving rod 212 moves downward to drive the fixed block 215 to move downward. The two ends of the annular block 23 are fixedly connected with a slider 231, one side of the slider 231 is slidably connected to the inner wall of the recovery tank 21, and the interior of the slider 231 is provided with a through groove, so that the fixed block 215 moves downward against the slider 231, and the upper side of the support plate 211 is fixedly connected to the inner top wall of the recovery tank 21 with a second moving rod 213, and the second moving rod 213 is symmetrically arranged with the first moving rod 212, and the first moving rod 212 and the second moving rod 213 both pass through the interior of the through groove, and the second moving rod The rod wall of the first moving rod 213 and the first moving rod 212 are fixedly connected with three sets of fixing blocks 215, and the diameter of the fixing blocks 215 is larger than the diameter of the through slot. The fixing blocks 215 on the first moving rod 212 are located on the upper side of the slider 231, and the fixing blocks 215 on the second moving rod 213 are located on the lower side of the slider 231. When the slider 231 moves downward, the slider 231 on the second moving rod 213 moves upward, and the fixing blocks 215 on the second moving rod 213 have an impact on the slider on the second moving rod 213. Block 231 acts as a limiter, so that when the slider 231 moves downward, it drives the annular block 23 to swing back and forth. The swinging annular block 23 drives the nozzle 234 to spray the exhaust gas inside the recovery tank 21 up and down, so that the spray liquid will impact the inner wall of the recovery tank 21 at different positions, thereby forming a more uniform and larger liquid film on the entire inner wall surface. Compared with the fixed nozzle 234, this dynamic spraying method can allow the exhaust gas to have more contact opportunities with the liquid film, and more effectively capture particulate matter in the exhaust gas.

[0046] See also Fig.10 As shown, the annular block 23 includes a side plate 233 fixedly connected to the inner wall of the annular block 23, and the other end of the side plate 233 is rotatably connected to the spray liquid inlet pipe 214. The annular block 23 drives the side plate 233 to swing synchronously during spraying, and the swinging side plate 233 fans the exhaust gas inside the recovery tank 21, thereby accelerating the flow speed of the exhaust gas, increasing the relative speed between the exhaust gas and the spray liquid, strengthening the mass transfer process between gas and liquid, promoting the transfer of pollutants in the exhaust gas to the spray liquid, accelerating the purification speed, and improving the overall efficiency of the exhaust gas treatment equipment. Combined with the uniform liquid film formed by the nozzle 234 spraying toward the inner wall, the exhaust gas can be treated more consistently in various parts, thereby improving the stability and reliability of the treatment effect and preventing the problem of substandard treatment due to uneven distribution of exhaust gas.

[0047] When the present invention is used, the motor 121 is started to drive the turntable 122 to rotate, and the turntable 122 drives the rack 125 to move back and forth through the connecting rod 124, so that the gear 126 rotates to drive the stirring rod 111 to rotate forward and reversely to stir the raw materials in the fermentation tank 11. Since the screw rod 128 at the upper end of the stirring rod 111 is threadedly connected with the gear 126, the screw rod 128 drives the stirring rod 111 to rotate and move up and down at the same time, so that the raw materials in the fermentation tank 11 are fully stirred, so that the raw materials are mixed evenly, ensuring that the wine koji is evenly mixed. The alcohol is distributed in the raw materials, which is beneficial to the smooth progress of the subsequent saccharification and fermentation process and improves the alcohol production. During the stirring process, the turntable 122 rotates to drive the No. 1 rotating rod 132 to rotate, and the No. 1 rotating rod 132 drives the No. 2 rotating rod 133 to swing back and forth. When the swinging No. 2 rotating rod 133 drives the piston rod 134 to move upward, the air pressure below the piston cylinder 13 is reduced at this time. Under the action of the pressure difference, the waste gas inside the fermentation tank 11 is sucked into the inside of the piston cylinder 13 and transported to the inside of the recovery tank 21 through the connecting air pipe 136;

[0048] The exhaust gas enters the interior of the air intake pipe 22, and the gas pushes the movable plate 221 upward, so that the exhaust gas flows into the interior of the recovery tank 21 from the gap between the upper end of the air intake pipe 22 and the lower end of the movable plate 221. The movable plate 221 can effectively prevent the exhaust gas from leaking, and at the same time avoid the phenomenon of exhaust gas backflow. The spray liquid is transported from the spray liquid inlet pipe 214 to the annular block 23 through the diverter pipe 232, so that the spray liquid is sprayed onto the inner wall of the recovery tank 21, so that the spray liquid can be more evenly distributed on the inner wall of the recovery tank 21. The second rotating rod 133 drives the first moving rod 212 to move when it swings back and forth, and the first moving rod 212 moves downward to drive the fixed block 215 to move downward against the slider 231, so that when the slider 231 moves downward, it drives the annular block 23 to swing back and forth, and the swinging annular block 23 drives the spray head 234 to spray up and down, so that the spray liquid will impact the inner wall of the recovery tank 21 at different positions. This dynamic spraying method can allow the exhaust gas to have more contact opportunities with the liquid film, and more effectively capture the particulate matter in the exhaust gas;

[0049] The annular block 23 drives the side plate 233 to swing synchronously during spraying. The swinging side plate 233 fans the exhaust gas inside the recovery tank 21, thereby accelerating the flow speed of the exhaust gas, increasing the relative speed between the exhaust gas and the spray liquid, strengthening the mass transfer process between gas and liquid, and promoting the transfer of pollutants in the exhaust gas to the spray liquid, thereby accelerating the purification speed and improving the overall efficiency of the exhaust gas treatment equipment. Combined with the uniform liquid film formed by the nozzle 234 spraying toward the inner wall, the exhaust gas can be treated more consistently in various parts, thereby improving the stability and reliability of the treatment effect and preventing substandard treatment caused by uneven distribution of exhaust gas.
