Description

Technical Field

[0001] The utility model relates to the field of biogas preparation equipment, in particular to a new type of medium-high temperature anaerobic fermentation device. Background Art

[0002] Anaerobic fermentation is an important technical means for the resource treatment of organic waste. Traditional technologies usually adopt medium-temperature or high-temperature anaerobic fermentation. However, medium-temperature anaerobic fermentation has good operation stability but low fermentation efficiency, while high-temperature anaerobic fermentation has high efficiency but poor operation stability. At present, significant breakthroughs have been made in the anaerobic fermentation technology in the transition zone between medium temperature and high temperature, namely medium-high temperature (40°C - 45°C) anaerobic fermentation, which takes into account both the operation stability of medium-temperature anaerobic fermentation and the high efficiency of high-temperature anaerobic fermentation. The biogas production rate is significantly increased by 10% - 20% compared with both medium-temperature anaerobic fermentation and high-temperature anaerobic fermentation.

[0003] However, the efficient anaerobic flora in medium-high temperature anaerobic fermentation has relatively strict requirements for the fluctuation of fermentation temperature, and it is difficult for existing technical equipment to ensure the multi-level precise control of fermentation temperature. For example, a high-efficiency biomass medium-high temperature anaerobic fermentation system for producing natural gas and its process for producing natural gas with the publication number of CN117535123B include a raw material suspension station, a hydrolysis station, a main fermentation tank, a post-fermentation tank, a desulfurization station, and a phase separation ion system; the hydrolysis station provides an acidic environment to pre-treat biomass energy raw materials containing cellulose by acid degradation. The biomass energy raw materials pretreated by the acid degradation of the hydrolysis station produce biogas under the action of anaerobic bacteria in the main fermentation tank; the pre-digestion and decomposition tasks of cellulose in the desulfurized biomass provide necessary conditions for the normal fermentation of the main fermentation tank and the post-fermentation tank to produce biogas, improving the fermentation efficiency and biogas production rate. However, it is difficult to accurately control the temperature during the biomass fermentation process in the main fermentation tank and the post-fermentation tank, and it cannot take into account both the fermentation efficiency and the stability during fermentation. Summary of the Utility Model

[0004] Aiming at the current anaerobic fermentation equipment's difficulty in accurately controlling the fermentation temperature and its inability to take into account both the efficiency of anaerobic fermentation and the stability during fermentation, the utility model proposes a new type of medium-high temperature anaerobic fermentation device, which can accurately control the temperature during the anaerobic fermentation process and pre-heat the materials entering the anaerobic fermentation equipment to ensure the efficiency of anaerobic fermentation and the stability during fermentation.

[0005] In order to achieve the above technical effects, the utility model proposes:

[0006] A new type of medium and high temperature anaerobic fermentation device includes an anaerobic fermentation unit and a temperature control unit. The anaerobic fermentation unit includes an adjustment component and an anaerobic fermentation component connected to each other. Inside the anaerobic fermentation component, there is a temperature monitoring component spirally arranged in the vertical direction. The temperature control unit includes a first temperature control component and a second temperature control component. The first temperature control component is connected to the adjustment component, and the second temperature control component is connected to the anaerobic fermentation component. The adjustment component adjusts and mixes the organic materials and transports them into the anaerobic fermentation component. On the inner side of the anaerobic fermentation component, there is a temperature monitoring component spirally arranged in the vertical direction. The first temperature control component is connected to the adjustment component and controls the temperature of the organic materials in the adjustment component. The second temperature control component is connected to the anaerobic fermentation component and cooperates with the temperature monitoring component to control the temperature of the anaerobic fermentation component.

[0007] The anaerobic fermentation component is in the shape of a tank. There is a feed inlet near the bottom part on the side of the anaerobic fermentation component, and a discharge outlet and a reflux port near the top part on the side of the anaerobic fermentation component. The reflux port is connected to the feed inlet. The organic materials transported by the adjustment component are input through the feed inlet of the anaerobic fermentation component, and the biogas slurry generated by fermentation inside the anaerobic fermentation component is output from the discharge outlet.

[0008] A reflux pump assembly is arranged between the reflux port and the feed inlet. The reflux pump assembly pumps the biogas slurry generated by fermentation inside the anaerobic fermentation component into the feed inlet. The reflux ratio of the biogas slurry pumped into the feed inlet to the materials entering the feed inlet ranges from 3:1 to 6:1. The reflux pump assembly returns the biogas slurry in the anaerobic fermentation component to the feed inlet. The biogas slurry and the organic slurry entering the feed inlet enter the anaerobic fermentation component together, strengthening the material flow state of the upper and lower layers inside the anaerobic fermentation component and making the fermentation more sufficient.

[0009] The anaerobic fermentation unit further includes a buffer component, and the buffer component is connected to the anaerobic fermentation component.

[0010] A feed component is arranged between the adjustment component and the anaerobic fermentation component, and a discharge component is arranged between the anaerobic fermentation component and the buffer component.

[0011] A cloth and water distribution pipe is arranged on the inner bottom surface of the anaerobic fermentation component. The cloth and water distribution pipe is in a fence shape and is connected to the feed inlet. The fence-shaped cloth and water distribution pipe is arranged on the inner ground of the anaerobic fermentation component, making the cloth and water distribution more uniform.

[0012] The second temperature control component includes a second heat exchange component and a self-control device. The second heat exchange component is arranged on the outer surface of the anaerobic fermentation component, and the self-control device is connected to the temperature monitoring component. The temperature monitoring component is connected to the self-control device and transmits real-time temperature data to the self-control device. The self-control device controls the second heat exchange component connected to the outer side of the anaerobic fermentation component to control the temperature of the anaerobic fermentation component.

[0013] The first temperature control component controls the temperature inside the adjustment component within the range of 44°C to 46°C, and the second temperature control component controls the temperature inside the anaerobic fermentation component within the range of 43.5°C to 44.5°C.

[0014] The temperature monitoring component is divided into several groups of temperature monitoring layers in the vertical direction on the side of the anaerobic fermentation component, and each group of the temperature monitoring layers is provided with at least four of the temperature monitoring components.

[0015] Stirrers are provided at the tops of the adjustment component and the anaerobic fermentation component, and the stirring speed of the stirrers can be adjusted.

[0016] The beneficial effects of the present utility model are:

[0017] The spiral arrangement of the temperature monitoring component precisely monitors the temperature during the anaerobic fermentation process. In combination with the temperature control unit for regulating the temperature of the anaerobic fermentation unit, the temperature during the anaerobic fermentation process is maintained within the optimal temperature range for medium and high-temperature anaerobic fermentation, improving the efficiency of anaerobic fermentation while ensuring the stability of the fermentation process.

[0026] The present utility model provides a new type of medium and high temperature anaerobic fermentation device. The following describes the preferred embodiments of the new type of medium and high temperature anaerobic fermentation device.

[0027] Embodiment 1

[0028] As Figure 1 shown, the adjusting assembly 11, the anaerobic fermentation assembly 12 and the buffer assembly 13 form the anaerobic fermentation unit 1. The temperature control unit 2 includes the first temperature control component 21 and the second temperature control component 22. The adjusting assembly 11 mixes and adjusts the raw materials to form the material to be fermented, and pre-heats the material through the first temperature control system. Then the material enters the anaerobic fermentation assembly 12 for anaerobic fermentation. The second temperature control component 22 controls the temperature of the anaerobic fermentation assembly 12 to keep the temperature in the anaerobic fermentation assembly 12 at the optimal temperature for medium and high temperature anaerobic fermentation. Biogas and biolymph are generated during the anaerobic fermentation process. The biogas is collected, and the biolymph enters the buffer assembly 13 for post-fermentation and precipitation.

[0029] As Figure 2As shown in the figure, a stirrer 4 is provided on the adjustment assembly 11. The stirrer 4 mixes the organic raw materials and water entering the adjustment assembly 11 to form an organic slurry. During this process, the stirrer 4 can adjust the stirring speed. At the same time, the first temperature control assembly 21 pre-heats the adjustment assembly 11; the organic slurry is transported into the first temperature control assembly 21 through the feeding assembly 3, and the first temperature control assembly 21 controls the temperature of the organic slurry at 44°C to 46°C; then the organic slurry enters the anaerobic fermentation assembly 12. A reflux pump 124 between the feed inlet 121 and the reflux port 123 of the anaerobic fermentation assembly 12 pumps the biogas slurry inside the anaerobic fermentation assembly 12 into the feed inlet 121. The biogas slurry and the organic slurry are mixed and enter the feed inlet 121 of the anaerobic fermentation assembly 12, and are evenly arranged at the bottom inside the anaerobic fermentation assembly 12 through a water distribution and cloth pipe 125 connected to the feed inlet 121 inside the anaerobic fermentation assembly 12; the stirrer 4 at the top of the anaerobic fermentation assembly 12 stirs the organic slurry, biogas slurry and biogas residue inside it. During this process, the stirrer 4 can adjust the stirring speed; the temperature monitoring assembly 14 arranged on the inner side surface of the anaerobic fermentation assembly 12 monitors the temperature inside the anaerobic fermentation assembly 12 in real time. It is arranged in a spiral shape in the vertical direction on the inner surface of the anaerobic fermentation assembly 12 and transmits the temperature data to the automatic control device 222 of the second temperature control assembly 22. The automatic control device 222 controls the second heat exchange assembly 221 connected to the outer surface of the anaerobic fermentation assembly 12. The second heat exchange assembly 221 controls the temperature inside the anaerobic fermentation assembly 12 at 43.5°C to 44.5°C, so that the inside of the anaerobic fermentation assembly 12 is at the optimal temperature for medium and high temperature anaerobic fermentation; the biogas generated after the medium and high temperature anaerobic fermentation of the organic slurry inside the anaerobic fermentation assembly 12 is used for power supply and heating. The biogas slurry generated enters the buffer assembly 13 through the discharge port 122 via the discharge assembly 5. The biogas slurry undergoes post-fermentation and precipitation. The biogas slurry after post-fermentation and precipitation forms clear liquid and concentrated liquid and enters the subsequent treatment unit.

[0030] As Figure 3 shown, the anaerobic fermentation assembly 12 is in the shape of a tank. A feed inlet 121 is provided near the bottom on the side of the anaerobic fermentation assembly 12, and a discharge port 122 and a reflux port 123 are provided near the top on the side of the anaerobic fermentation assembly 12. A reflux pump 124 is arranged between the reflux port 123 and the feed inlet 121. The reflux pump 124 can pump the biogas slurry in the anaerobic fermentation assembly 12 into the feed inlet 121. The organic slurry and the biogas slurry are mixed and enter the anaerobic fermentation assembly 12, and are evenly transported to the bottom of the anaerobic fermentation assembly 12 by the cloth water pipe 125, strengthening the material flow state of the upper and lower layers inside the anaerobic fermentation assembly 12, making the material temperatures of the upper and lower layers inside the anaerobic fermentation assembly 12 more uniform, and making the anaerobic fermentation reaction more efficient. During the residence fermentation stage of the material, the biogas slurry can be circulated separately between the reflux port 123 and the feed inlet 121.

[0031] As Figure 4As shown in the figure, the cloth water pipe 125 of the cloth is composed of five mutually parallel branch pipes and a main pipe that is perpendicular to and connected to the above four pipes. The five branch pipes are composed of three shorter pipes and two longer pipes arranged alternately. The five branch pipes are arranged at intervals at the bottom of the anaerobic fermentation assembly 12 to achieve the purpose of evenly distributing the materials and biogas slurry at the bottom of the anaerobic fermentation assembly 12.

[0032] As Figure 5 shown in the figure, the temperature monitoring assembly 14 is installed spirally on the inner side of the anaerobic fermentation assembly 12. The temperature monitoring assembly 14 is divided into 3 temperature monitoring layers 15 in the vertical direction on the side of the anaerobic fermentation assembly 12, and 4 groups of the temperature monitoring assemblies 14 are arranged in each temperature monitoring layer 15. The temperature monitoring assembly 14 is arranged spirally on the inner side of the anaerobic fermentation assembly 12 to more accurately monitor the temperature at different horizontal positions on the inner surface of the anaerobic fermentation assembly 12.

[0033] Using food waste as raw material, the working process of the new medium and high temperature anaerobic fermentation device is as follows:

[0034] Before the food waste enters the new medium and high temperature anaerobic fermentation device, it undergoes pretreatment unit sorting, sand and impurity removal, and grease extraction to form an organic slurry. At this time, the temperature of the organic slurry is 55°C to 65°C. The organic slurry enters the adjustment assembly 11, and the adjustment assembly 11 cooperates with the stirring of the stirrer 4 to mix and adjust the organic slurry, and is transported to the feed inlet 121 of the anaerobic fermentation assembly 12 through the feeding assembly 3. During this process, the first temperature control assembly 21 reduces the temperature of the organic slurry to 44°C to 46°C. The organic slurry entering the anaerobic fermentation assembly 12 is mixed with the biogas slurry pumped out from the return port 123. The reflux ratio of the returned biogas slurry to the organic slurry is not less than 5:1. The mixed organic slurry and biogas slurry enter the bottom of the anaerobic fermentation assembly 12 through the cloth water pipe 125 for anaerobic fermentation. During this period, the stirrer 4 stirs the organic slurry and biogas slurry in the anaerobic fermentation assembly 12 to ensure sufficient fermentation. The temperature monitoring assembly 14 is arranged inside the anaerobic fermentation assembly 12 to monitor the temperature inside the anaerobic fermentation assembly 12 and transmit the temperature data to the automatic control system of the second temperature control assembly 22. The automatic control system controls the second heat exchange assembly 221 connected to the outer side of the anaerobic fermentation assembly 12 to control the temperature inside the anaerobic fermentation assembly 12 at 43.5°C to 44.5°C and operate stably. The organic slurry undergoes medium and high temperature anaerobic fermentation in the anaerobic fermentation assembly 12 for 15 to 25 days, during which biogas and biogas slurry are generated. The biogas is collected for power generation and heating. The biogas slurry enters the buffer assembly 13 through the discharge assembly 5 for post-fermentation and precipitation treatment, and the clarified liquid and concentrated liquid after precipitation enter the subsequent treatment unit.

[0035] Example 2: The anaerobic fermentation unit 1 includes a connected regulating component 11 and an anaerobic fermentation component 12. A feeding component 3 is arranged between the regulating component 11 and the anaerobic fermentation component 12. The regulating component 11 is used to mix and regulate organic materials and water, etc. The anaerobic fermentation component 12 is used to perform medium-high temperature anaerobic fermentation on the organic slurry from the regulating component 11. The temperature control unit 2 includes a first temperature control component 21 and a second temperature control component 22. The first temperature control component 21 is connected to the regulating component 11, and the second temperature control component 22 is connected to the anaerobic fermentation component 12. The first temperature control component 21 controls the temperature of the regulating component 11, pre-heats the organic slurry in the regulating component 11, and makes the organic slurry reach 44°C to 46°C before entering the anaerobic fermentation component 12. The second temperature control component 22 adjusts the temperature of the anaerobic fermentation component 12 and controls the organic slurry in the anaerobic fermentation component 12 at 43.5°C to 44.5°C.

[0036] The second temperature control component 22 includes a second heat exchange component 221 and an automatic control device 222. The second heat exchange component 221 is arranged on the outer side of the anaerobic fermentation component 12, and the automatic control device 222 automatically regulates the second heat exchange component 221. A spiral temperature monitoring component 14 is arranged vertically on the inner side of the anaerobic fermentation component 12. The temperature monitoring component 14 monitors the temperature of the organic materials in the anaerobic fermentation component 12. The temperature monitoring component 14 is divided into several temperature monitoring layers 15 vertically on the inner side of the anaerobic fermentation component 12. Each group of temperature monitoring layers 15 is provided with at least four temperature monitoring components 14. The temperature monitoring component 14 is connected to the automatic control device 222, and the temperature monitoring component 14 transmits real-time temperature data to the automatic control device 222. The automatic control device 222 regulates the second heat exchange component 221 according to the real-time temperature data, and then controls the temperature of the anaerobic fermentation component 12.

[0037] The buffer component 13 is connected to the anaerobic fermentation component 12. A discharging component 5 is arranged between the buffer component 13 and the anaerobic fermentation component 12. The buffer component 13 is used to perform post-fermentation and precipitation on the biogas slurry after medium-high temperature anaerobic fermentation in the anaerobic fermentation component 12, and perform subsequent treatment on the clear liquid and concentrated liquid generated after post-fermentation and precipitation.

[0038] On the side of the anaerobic fermentation assembly 12, near the top position, there are a discharge port 122 and a reflux port 123. Near the bottom position on the side, there is a feed port 121. The reflux port 123 is connected to the feed port 121, and a reflux pump assembly 124 is arranged between the reflux port 123 and the feed port 121. The reflux pump assembly 124 pumps the biogas slurry in the anaerobic fermentation assembly 12 out from the reflux port 123, and the biogas slurry enters the feed port 121. The biogas slurry and the organic slurry enter the feed port 121, and the reflux ratio range of the biogas slurry and the organic slurry is 3:1 to 6:1. The setting of the reflux pump assembly 124 strengthens the material flow state of the upper and lower layers in the anaerobic fermentation assembly 12, makes the material temperatures of the upper and lower layers in the anaerobic fermentation assembly 12 more uniform, and makes the anaerobic fermentation reaction more efficient. On the inner bottom surface of the anaerobic fermentation assembly 12, there is a cloth and water distribution pipe 125. The cloth and water distribution pipe 125 is in a fence shape. The cloth and water distribution pipe 125 is connected to the feed port 121, and the biogas slurry and the organic slurry enter the bottom of the anaerobic fermentation assembly 12 through the cloth and water distribution pipe 125. On both the adjustment assembly 11 and the top of the anaerobic fermentation assembly 12, there is a stirrer 4, and the stirrer 4 can adjust the stirring speed.

[0039] Through the multi-stage precise temperature control of the temperature control unit 2, the temperature in the anaerobic fermentation assembly 12 is at the optimal temperature for medium and high-temperature anaerobic fermentation, with high and relatively stable anaerobic fermentation efficiency. The organic materials in the anaerobic fermentation assembly 12 produce biogas after anaerobic fermentation and are collected through the gas collection port at the top of the anaerobic fermentation assembly.

[0040] Using cow dung sewage as the raw material, the working process of the new medium and high-temperature anaerobic fermentation device is as follows:

[0041] The collected cow dung sewage is transported to the adjustment assembly 11 for mixing and adjustment, and the first temperature control component 21 heats the cow dung sewage to 44°C - 46°C. The cow dung sewage entering the anaerobic fermentation assembly 12 is mixed with the biogas slurry pumped out from the reflux port 123. The reflux ratio of the refluxed biogas slurry to the cow dung sewage is not less than 3:1. The mixed cow dung sewage and biogas slurry enter the bottom of the anaerobic fermentation assembly 12 through the cloth and water distribution pipe 125 for anaerobic fermentation. During this period, the stirrer 4 stirs the cow dung sewage and the biogas slurry in the anaerobic fermentation assembly 12. There is a temperature monitoring component 14 inside the anaerobic fermentation assembly 12 to monitor the temperature in the anaerobic fermentation assembly 12 and transmit the temperature data to the automatic control system of the second temperature control component 22. The automatic control system controls the second heat exchange component 221 connected to the outer side of the anaerobic fermentation assembly 12 to control the temperature in the anaerobic fermentation assembly 12 at 43.5°C - 44.5°C and operate stably. The cow dung sewage stays in the anaerobic fermentation assembly 12 for 12 - 20 days. During this period, biogas and biogas slurry are produced. The biogas is collected for power generation and heating. The biogas slurry enters the buffer assembly 13 through the discharge assembly 5 for post-fermentation and precipitation treatment, and the clarified liquid and concentrated liquid after precipitation enter the subsequent treatment unit.
