Description

Technical Field

[0001] The invention belongs to the field of organic matter treatment, in particular to a biogas fermentation device. Background Art

[0002] Biogas fermentation, also known as anaerobic digestion, produces biogas from various fermentation feedstocks, such as feces, straw, and kitchen waste, achieving resource recycling. Biogas fermentation can be divided into three stages: hydrolysis, hydrogen and acid production, and methane production.

[0003] In the first stage of the hydrolysis process, the hydrolytic enzymes produced by hydrolytic bacteria hydrolyze high-molecular polymers such as cellulose, fat, protein and starch into soluble small molecules; in the second stage of the hydrogen and acid production process, the acid-producing bacteria further metabolize the hydrolyzed small molecules into even smaller molecular volatile organic acids, laying the foundation for methane production; in the third process of the methanogenesis stage, methanogens use hydrogen to reduce carbon dioxide to produce methane.

[0004] In a normally operating biogas fermentation tank, the rate at which non-methanogenic bacteria decompose and utilize organic matter will affect the rate at which methanogenic bacteria produce methane. Therefore, in order to increase the hydrolysis rate of non-methanogenic bacteria, the degradation effect of organic matter in the fermentation system can be improved by adding biogas fermentation biocatalysts.

[0005] Types of biogas fermentation biocatalysts include: enzymes, trace elements, adsorbents, and defoamers. Studies have shown that adding an appropriate amount of hydrolase can accelerate the degradation of cellulose in the fermentation raw materials, but the amount of hydrolase added should not be too high; the organic matter in the fermentation broth can provide the carbon and nitrogen elements required for microbial growth, while phosphorus needs to be added separately. By adding phosphate rock powder to the fermentation broth, it is beneficial to the growth of microorganisms, thereby increasing the fermentation rate; adsorbents can aggregate microorganisms, increase the density of microorganisms, and maintain the growth environment of microorganisms, thereby accelerating the rate of microbial degradation; foam will continue to be generated during the fermentation process, and foam will have an adverse effect on the fermentation of microorganisms. Polyether defoamers have good hydrophilicity, are easy to expand in water, and have strong defoaming ability, but the defoaming activity is short-lived, so defoamers need to be added intermittently during the fermentation reaction.

[0006] In existing biogas fermentation equipment, all biocatalysts are put into the fermentation tank at one time for fermentation reaction. During the fermentation process, it is impossible to timely supplement the required trace elements for the microorganisms in the fermentation liquid, and timely add enzymes, adsorbents and defoaming agents to increase the fermentation rate.

[0007] To this end, a biogas fermentation equipment was designed, which can intermittently add biogas fermentation biocatalysts such as enzymes, trace element adsorbents and defoaming agents into the fermentation tank to increase the rate of biogas fermentation. Summary of the Invention

DETAILED DESCRIPTION

[0050] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods;

[0051] like Figures 1 to 6 As shown, the present invention provides a biogas fermentation equipment 1, including a reactor 1, a motor 2, an electric heating wire 3, a feed pipe 4 and a support frame 5, wherein the support frame 5 is fixedly connected to the top of the reactor 1, the motor 2 is fixedly connected to the top of the support frame 5, and the output end of the motor 2 passes through the support frame 5 for providing power; a feed pipe 4 passes through one side of the reactor 1 for conveying fermentation raw materials; an electric heating wire 3 is provided on the inner wall of the reactor 1 for providing a heat source; and further comprising;

[0052] Stirring assembly; the stirring assembly is provided in the reactor 1 and is used to stir the fermentation raw materials in the reactor 1;

[0053] Adding component; the adding component is arranged in the reactor 1 and is used to add the catalyst;

[0054] Before processing the fermentation raw materials, the staff first turns on the electric heating wire 3 to preheat the reactor 1. After preheating for a certain period of time, the staff opens the feed pipe 4 and the fermentation raw materials are injected into the reactor 1. After the fermentation raw materials are injected, the feed pipe 4 is closed.

[0055] At this time, the staff starts the motor 2 fixedly connected to the support frame 5. After the motor 2 is started, it drives the stirring component to rotate. The rotating stirring component stirs the fermentation raw materials in the reactor 1. Driven by the stirring component, the adding component rotates; the rotating adding component sprays the catalyst stored inside it, which is sufficient to process the fermentation raw materials, into the reactor 1. The powder is fully contacted and reacted with the fermentation raw materials under the stirring of the stirring component. The adding component intermittently adds catalyst to the reactor 1 during the rotation process to increase the degradation rate during microbial fermentation.

[0056] During fermentation, the stirring assembly is rotated to scrape off the fermentation raw materials adhering to the inner wall of the reactor 1, thereby improving the cleanliness of the reactor 1 and preventing the dirt adhering to the inner wall of the reactor 1 from affecting the next fermentation.

[0057] As a specific embodiment of the present invention, the stirring assembly includes:

[0058] Boss 6, said boss 6 is located below the output end of the motor 2, said boss 6 is slidably connected to the inner wall of the reactor 1, and a notch 7 is provided on one side of said boss 6;

[0059] A scraper 8, the scraper 8 is fixed to the end of the boss 6 away from the output end of the motor 2 and is slidably connected to the inner wall of the reactor 1. The number of the scraper 8 is more than one;

[0060] A rotating rod 9 is located in the reactor 1. One end of the rotating rod 9 passes through the boss 6 and is fixed to the output end of the motor 2. The rotating rod 9 is rotatably connected to the boss 6.

[0061] A spiral piece 11, wherein the spiral piece 11 is fixed to the rotating rod 9;

[0062] The baffle 12 is fixed on the spiral sheet 11 .

[0063] As a specific embodiment of the present invention, the additional component includes:

[0064] A groove 13 is provided on the top of the reactor 1;

[0065] A first groove 131 is provided on the top of the reactor 1;

[0066] The card block 14 is provided in the groove 13 and is slidably connected to the inner wall of the groove 13; the card block 14 is engaged with the notch 7 on the boss 6;

[0067] A first clamping block 141 is disposed in the first groove 131 and is slidably connected to the inner wall of the first groove 131;

[0068] The air bag 15 is provided in the top cavity of the reactor 1;

[0069] A filling port 17, which passes through the top of the reactor 1 and is connected to the air bag 15;

[0070] A discharge pipe 18 , one end of which is connected to the air bag 15 and the other end of which passes through the reactor 1 ; used for discharging the catalyst;

[0071] A pull plate 19, which is sleeved on the rotating rod 9 and fixedly connected to the rotating rod 9;

[0072] The connecting column 21 is fixed to the top of the boss 6 , and the connecting column 21 is fixed to the end of the pull plate 19 away from the rotating rod 9 via a spring 22 .

[0073] When fermentation is required, the staff can first turn on the electric heating wire 3 to preheat the reactor 1 in cold weather to prevent the fermentation raw material temperature from being too low, which will lead to a decrease in the activity of microorganisms; after preheating for a certain period of time, the staff opens the feed pipe 4 to inject the fermentation raw material into the reactor 1, and closes the feed pipe 4 after the fermentation raw material is injected.

[0074] At this time, the staff starts the motor 2 fixedly connected to the support frame 5. After the motor 2 is started, it drives the rotating rod 9 to rotate. The rotating rotating rod 9 drives the spiral piece 11 fixedly connected to itself to rotate. At the same time, the baffle 12 fixedly connected to the upper surface of the spiral piece 11 also rotates with the rotation of the spiral piece 11. Under the stirring of the spiral piece 11 and the push of the baffle 12, the fermentation raw materials at the bottom of the reactor 1 can be flipped up and down by the baffle 12, thereby improving the fluidity of the fermentation raw materials and making the fermentation raw materials in the reactor 1 heated evenly.

[0075] Before the motor 2 is started, the staff fills the airbag 15 with catalyst from the filling port 17, and the block 14 in the groove 13 at the top of the reactor 1 is engaged with the notch 7 on the boss 6. When the motor 2 is started, the rotating rod 9 drives the pull plate 19 fixedly connected to the rotating rod 9 to rotate. At this time, because the block 14 is engaged with the notch 7 on the boss 6, the boss 6 cannot rotate. The pull plate 19 pulls the spring 22 fixedly connected between the pull plate 19 and the connecting column 21. During the pull plate 19's rotation, the pull plate 19 contacts the block 14 engaged with the notch 7, and as the pull plate rotates, the block 14 is pushed out of the notch 7 on the boss 6.

[0076] When the block 14 is ejected, the block 14 pushes the connecting rod 16 to slide in the groove 13, driving the push plate 162 to squeeze the airbag 15. At the same time, the No. 1 spring 163 on the push plate 162 is stretched. After the airbag 15 is squeezed, the catalyst in the airbag 15 is ejected from the discharge pipe 18. The ejected catalyst falls into the reactor 1 and is fully mixed with the fermentation raw materials pushed up from the bottom of the reactor 1 by the spiral sheet 11 and the baffle 12. The catalyst fully contacts and reacts with the fermentation raw materials under the stirring action of the stirring assembly, thereby improving the fermentation efficiency.

[0077] After the pulling plate 19 pushes the block 14 and the notch 7 apart, the block 14 and the notch 7 are completely separated. At this time, the spring 22 stretched between the pulling plate 19 and the connecting column 21 will return to its original state, driving the boss 6 to rotate around the rotating rod 9; when the notch of the boss 6 is engaged with one of the blocks 14, the other blocks 14 are abutted against the boss 6, and the No. 1 spring 163 is in a stretched state in the No. 1 groove 131. When the notch 7 on the boss 6 rotates to the position of the No. 1 block 141, the resistance of the No. 1 block 141 disappears, and the stretched No. 1 spring 163 recovers its deformation, causing the No. 1 block 141 to slide along the No. 1 groove 131, and the No. 1 block is engaged with the notch 7. At the same time, the compressed airbag 15 is inhaled through the discharge pipe 18, and the airbag 15 expands and returns to its original state.

[0078] As the pull plate 19 continues to rotate, it drives the block 14, the connecting rod 16, and the airbag 15 to repeat the above-mentioned working process, causing the boss 6 to produce intermittent movement;

[0079] At the same time, the intermittently moving boss 6 drives the rotation of the scraper 8 in the reactor 1. On the one hand, the rotating scraper 8 scrapes off the fermentation raw materials on the inner wall of the reactor 1, so that no residue of the fermentation raw materials will be left in the reactor 1, thereby preventing the fermentation raw materials from adhering to the inner wall of the reactor 1 for a long time and affecting the subsequent processing effect of the fermentation raw materials;

[0080] On the other hand, the rotating scraper 8 also stirs the fermentation raw materials in the reactor 1, so that the catalyst and the fermentation raw materials fully react, further improving the fermentation efficiency;

[0081] Repeat the above operation when the fermentation raw materials need to be processed again.

[0082] As a specific embodiment of the present invention, the reactor 1 is provided with a purification component for purifying the generated fermentation gas, and the purification component includes:

[0083] A purification box 24, the purification box 24 is fixed to one side of the reactor 1;

[0084] An exhaust pipe 25 , one end of which passes through the reactor 1 ; the other end of which passes through the top of the purification box 24 and extends to the bottom of the purification box 24 ;

[0085] A water inlet 26 , the water inlet 26 being fixed to the top of the purification box 24 ;

[0086] Before processing the fermentation raw materials, the staff injects lime water into the purification box 24 through the water inlet 26. During the fermentation process, the generated gas flows into the purification box 24 through the exhaust pipe 25. The lime water in the purification box 24 removes carbon dioxide in the fermentation gas, thereby improving the purity of the fermentation gas methane.

[0087] As a specific embodiment of the present invention, a through hole 27 is opened on one end of the exhaust pipe 25 away from the top of the purification box 24, and the number of the through hole 27 is more than one;

[0088] When the gas generated by the fermentation raw material treatment is passed into lime water from the exhaust pipe 25, a plurality of through holes 27 are opened on the exhaust pipe 25, and the gas is discharged from the plurality of through holes 27, thereby increasing the exhaust range of the exhaust pipe 25 and also accelerating the reaction rate of the carbon dioxide in the fermentation gas and the lime water. After the fermentation gas passes through the purification chamber to remove the carbon dioxide, a methane gas with a higher purity can be obtained.

[0089] As a specific embodiment of the present invention, a discharge port 28 is provided at the bottom of the reactor 1, and a chute 29 is provided at the discharge port 28. A filter screen 31 is slidably connected in the chute 29. A partition 32 is provided above the filter screen 31, and the partition 32 is slidably connected to the inner wall of the discharge port 28.

[0090] After the processing is completed, the staff pulls out the partition 32 that is slidably connected to the inner wall of the discharge port 28. After the partition 32 is pulled out, the fermentation raw materials in the reactor 1 flow through the discharge port 28 to the filter screen 31 in the discharge port 28. At this time, the fermentation raw materials on the filter screen 31 are filtered through the filter screen 31, so that the solid particles in the fermentation raw materials are blocked by the filter screen 31, so that the processed products of the fermentation raw materials are separated from the solid particles, and there is no need to separate the processed products again, which shortens the time for fermentation raw material processing and reduces cost waste.

[0091] In addition, after the treatment is completed, the catalyst in the airbag 15 is also completely used during the treatment process. At this time, the rotating adding component scrapes off the fermentation raw materials stuck on the inner wall of the reactor 1, thereby improving the cleanliness of the reactor 1, avoiding the fermentation raw materials stuck on the inner wall of the reactor 1 affecting the next fermentation raw material treatment, reducing the waste of products after the fermentation raw materials are processed, and improving the use effect of the reactor 1.

[0092] After all the fermentation raw materials are filtered, the staff pulls the filter screen 31, and the filter screen 31 slides along the chute 29 fixedly connected to the discharge port 28. During the sliding process, the solid particles on the filter screen 31 are scraped off by the discharge port 28, so that the filter screen 31 can be reused.

[0093] As a specific embodiment of the present invention, the end of the rotating rod 9 away from the boss 6 is fixedly connected to a stirring rod 33;

[0094] By adopting the above technical solution, a stirring rod 33 is fixedly connected to the end of the rotating rod 9 away from the boss 6. When the fermented residue passes through the discharge port 28, the rotating rotating rod 9 drives the stirring rod 33 to rotate, and the rotating stirring rod 33 stirs the residue to prevent the residue from clogging the discharge port when being discharged.

[0095] As a specific embodiment of the present invention, the material of the airbag 15 is silicone rubber;

[0096] The airbag 15 is made of silicone rubber, which has good thermal stability and is not easily expanded by heat due to temperature during operation, thereby reducing the danger of operation. At the same time, it has high mechanical strength and is more practical when the connecting rod 16 is matched with the airbag 15, thereby increasing the speed of removing the catalyst in the airbag 15.

[0097] As a specific embodiment of the present invention, the baffle 12 is in the shape of a circular arc;

[0098] By adopting the above technical solution, the baffle 12 on the spiral sheet 11 is in the shape of an arc. On the one hand, the rotating arc-shaped baffle 12 can drive a portion of the fermentation raw materials in the reactor 1 from the bottom to the top, so that the fermentation raw materials at the bottom can contact with the catalyst, thereby improving the fermentation efficiency;

[0099] On the other hand, the rotating arc-shaped baffle 12 increases the contact area with the fermentation raw materials in the reactor 1, accelerates the fluidity of the fermentation raw materials, improves the contact efficiency between the fermentation raw materials and the catalyst, promotes uniform heating of the fermentation raw materials, and improves the efficiency of the fermentation reaction.

[0100] The specific workflow is as follows:

[0101] When fermentation is required, the staff needs to turn on the electric heating wire 3 before processing the fermentation raw materials to preheat the reactor 1 to shorten the fermentation raw material processing time; after preheating for a certain period of time, the staff opens the feed pipe 4 to inject the fermentation raw materials into the reactor 1. After the fermentation raw materials are injected, the feed pipe 4 is closed;

[0102] At this time, the staff starts the motor 2 fixedly connected to the support frame 5. After the motor 2 is started, it drives the rotating rod 9 to rotate. The rotating rotating rod 9 drives the spiral piece 11 fixedly connected to itself to rotate. At the same time, the baffle 12 fixedly connected to the upper surface of the spiral piece 11 also rotates with the rotation of the spiral piece 11. Under the stirring of the spiral piece 11 and the push of the baffle 12, the fermentation raw materials at the bottom of the reactor 1 can be pushed up by the baffle 12, thereby improving the fluidity of the fermentation raw materials and improving the uniform heating of the fermentation raw materials in the reactor 1.

[0103] Before the motor 2 is started, the staff fills the catalyst into the airbag 15 at the filling port 17, and the block 14 in the groove 13 at the top of the reactor 1 is engaged with the notch 7 on the boss 6. When the motor 2 is started, the rotating rod 9 drives the pull plate 19 fixedly connected to the rotating rod 9 to rotate. At this time, because the block 14 is engaged with the notch 7 on the boss 6, the boss 6 cannot rotate. The pull plate 19 pulls the spring 22 fixedly connected between the pull plate 19 and the connecting column 21. During the rotation of the pull plate 19, the pull plate 19 contacts the block 14 engaged with the notch 7. As the pull plate 19 rotates, the pull plate 19 gradually pushes the boss 6 out of the notch 7.

[0104] When the block 14 is ejected, the block 14 pushes the connecting rod 16 to slide in the groove 13, driving the push plate 162 to squeeze the airbag 15. At the same time, the No. 1 spring 163 on the push plate 162 is stretched. After the airbag 15 is subjected to air pressure, the catalyst in the airbag 15 is ejected from the discharge pipe 18. The ejected catalyst falls into the reactor 1 and is fully mixed with the fermentation raw materials pushed up from the bottom of the reactor 1 by the spiral sheet 11 and the baffle 12. Under the stirring action of the stirring assembly, the catalyst fully contacts and reacts with the fermentation raw materials, thereby improving the reaction efficiency of the catalyst in the fermentation raw materials.

[0105] After the pull plate 19 pushes the block 14 and the notch 7 apart, the spring 22 stretched between the pull plate 19 and the connecting column 21 will return to its original shape, driving the boss 6 to rotate with the rotating rod 9 as the center. When the notch 7 on the boss 6 rotates to the position of the No. 1 block 141, the resistance of the No. 1 block 141 disappears, and at the same time, the No. 1 spring 163 in tension recovers its deformation, pushing the No. 1 connecting rod toward 161 and the No. 1 block 141 toward the notch 7, thereby causing the No. 1 block 141 to engage with the notch 7 on the boss 6; at the same time, the compressed airbag 15 inhales air through the discharge pipe 18, and the airbag 15 expands and returns to its original shape. When the airbag 15 expands, as the pull plate 19 continues to rotate, it drives the components of the block 14, the connecting rod 16, and the airbag 15 to repeat the above-mentioned working process, causing the boss 6 to produce intermittent movement.

[0106] At the same time, the intermittently moving boss 6 drives the rotation of the scraper 8 in the reactor 1. On the one hand, the rotating scraper 8 scrapes off the fermentation raw materials that are in contact with the inner wall of the reactor 1, so that other fermentation raw materials in the reactor 1 continue to contact the inner wall, thereby preventing the fermentation raw materials from adhering to the inner wall of the reactor 1 for a long time, reducing the adhesion of the fermentation raw materials to the high-temperature inner wall of the reactor 1, and improving the heat transfer of the reactor 1;

[0107] On the other hand, the rotating scraper 8 also stirs the fermentation raw materials in the reactor 1, so that the catalyst and the fermentation raw materials fully react, further improving the fermentation reaction efficiency;

[0108] After the processing is completed, the staff pulls out the partition 32 that is slidably connected to the inner wall of the discharge port 28. After the partition 32 is pulled out, the fermentation raw materials in the reactor 1 flow through the discharge port 28 to the filter screen 31 in the discharge port 28. At this time, the fermentation raw materials on the filter screen 31 are filtered through the filter screen 31, and the fermented residue is filtered;

[0109] A stirring rod 33 is fixedly connected to the end of the rotating rod 9 away from the boss 6. When the fermented raw materials pass through the discharge port 28, the rotating rotating rod 9 drives the stirring rod 33 to rotate, stirring the fermented raw materials and improving the fluidity of the fermented raw materials.

[0110] In addition, after the treatment is completed, the catalyst in the air bag 15 is also completely used in the treatment process. At this time, the adding component is rotated to scrape off the residues adhering to the inner wall of the reactor 1, thereby improving the cleanliness of the reactor 1, avoiding the fermentation raw materials adhering to the inner wall of the reactor 1 and affecting the next fermentation, and improving the use effect of the reactor 1;

[0111] After all the fermentation raw materials have been filtered, the staff pulls the filter screen 31, and the filter screen 31 slides along the chute 29 fixedly connected to the discharge port 28.
