Description

Technical Field

[0001] The invention belongs to the technical field of anaerobic fermentation, and in particular relates to an integrated anaerobic fermentation device. Background Art

[0002] Anaerobic fermentation can be divided into two categories: wet fermentation and dry fermentation. Currently, anaerobic wet fermentation has been widely used in biogas production from low-concentration materials such as livestock manure and various organic wastewaters. However, since most biogas projects in my country do not achieve cogeneration, anaerobic wet fermentation consumes a large amount of its own energy in cold regions, resulting in low economic benefits or even losses. This has greatly limited the promotion and application of anaerobic wet fermentation in cold northern regions. In addition, anaerobic wet fermentation has low material concentration, high water consumption, low equipment utilization, and high post-processing costs for biogas residue and liquid. Therefore, dry anaerobic fermentation has become a research hotspot in recent years.

[0003] For example, the utility model patent with patent authorization announcement number: CN211522159U discloses an integrated system of dry anaerobic fermentation and organic fertilizer fermentation; the system includes an anaerobic fermentation tank and an aerobic fermentation tank for organic fertilizer that are connected to each other, and the inclined tank wall at the bottom of the anaerobic fermentation tank is inclined in the opposite direction to the inclined tank wall at the top of the aerobic fermentation tank for organic fertilizer; the upper part of the anaerobic fermentation tank is provided with a raw material feed inlet, a liquid biogas feed inlet and a biogas outlet, and the bottom inclined tank wall of the anaerobic fermentation tank is provided with a biogas residue outlet, a biogas injection inlet and a biogas liquid outlet from the upper end to the lower end in sequence; the top inclined tank wall of the aerobic fermentation tank for organic fertilizer is provided with a biogas residue inlet, an aerobic fermentation agent inlet and a waste gas outlet; the biogas residue outlet is connected to the biogas residue inlet through a biogas residue discharging device.

[0026] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

When the fermentation device needs to be replaced from one project to another, even if there is a difference in the terrain between the two projects, as long as The floor areas of the two projects are not much different, and both can be directly replaced from one project to another by replacing the position of the welding plate 102 and the spray tank 201 installed in the fermentation chamber 101; there is no need to redesign a new set of fermentation equipment to adapt to the terrain of the new project, which greatly saves the time for design, construction and installation of the fermentation equipment, and can be used for the new biogas project in a shorter time, solving the problem that the existing dry anaerobic fermentation system adopts an integrated design to achieve stable operation of the system, and such a design cannot directly adapt to small-scale biogas projects such as livestock and poultry manure and crop straw with diverse terrain changes; therefore, it is often necessary to redesign a new set of dry anaerobic fermentation system to adapt to the terrain of the project according to the terrain changes of the current project, thereby delaying the speed and efficiency of the small-scale biogas project.

[0028] Specifically, the spray assembly 2 of this scheme also includes a spray pipe 202, an extension pipe 203, a plurality of spray heads 204 and a spray pump 205. The spray pipe 202 is arranged at the top of the fermentation chamber 101. The axial direction of the spray pipe 202 is the same as the length direction of the fermentation chamber 101. The spray pipe 202 is provided with a plurality of spray ports, and the plurality of spray ports are arranged at equal intervals along the axial direction of the spray pipe 202. The plurality of spray ports are matched one-to-one with the plurality of spray heads 204, and any spray head 204 is arranged at the corresponding spray port; the fermentation chamber 101 is provided with a connecting port, one end of the spray pipe 202 is sealed, and the other end is connected to the connecting port. Sealed connection, the two ends of the extension pipe 203 are sealed and connected to the connecting port and the bottom of the spray tank 201 respectively, the spray pump 205 is arranged on the side wall outside the fermentation chamber 101, and the spray pump 205 is connected to the extension pipe 203; it should be noted that the spray tank 201 is loaded with permeate, and the fermentation chamber 101 is piled with livestock and poultry manure, and then the spray pump 205 works to pump the permeate in the spray tank 201 into the extension pipe 203, and then the permeate flows from the extension pipe 203 into the spray pipe 202, and finally flows into the fermentation chamber 101 through the spray head 204, and reacts with livestock and poultry manure to form biogas.

[0029] In addition, the fermentation component 1 of this scheme also includes a sealing plate 103, and the fermentation chamber 101 is provided with a connecting slot, which is connected to the connecting port. The sealing plate 103 can be slidably arranged in the connecting slot, and the sealing plate 103 is provided with a sealing port, which can lock or release its connecting and matching relationship with the connecting port; when the sealing port on the sealing plate 103 and the connecting port are connected to each other, the permeate located in the spray tank 201 can flow into the spray pipe 202 through the connecting port; when the sealing port on the sealing plate 103 and the connecting port are no longer connected to each other, the permeate located in the spray tank 201 cannot flow into the spray pipe 202 through the connecting port.

[0030] According to the above embodiment, since the spray tank 201 and the welding plate 102 of the present solution are detachably connected, such a setting has the problem that during the operation of the spray tank 201, due to the force of the external environment, the spray tank 201 may fall off from the welding plate 102, thereby causing the spray tank 201 to be unable to continue to work normally, and the biogas located in the fermentation chamber 101 will overflow from the connecting port to the outside world; in order to solve the problem that the biogas located in the fermentation chamber 101 overflows from the connecting port during the period when the spray tank 201 cannot work normally, the fermentation component 1 of the present solution further includes a reset spring 104, a drive rod 105, a hinged rod 106 and a pressing block 107, and the fermentation chamber 10 1 and the welding plate 102 are jointly formed with a movable slot, which is communicated with the mounting hole and the connecting slot respectively. The pressing block 107 is arranged at one end of the movable slot near the mounting hole in a lifting manner. The hinge rod 106 is arranged in the movable slot. The middle end of the hinge rod 106 is hinged in the movable slot. The bottom end of the pressing block 107 is hinged to one end of the hinge rod 106 slidably along the axis direction of the hinge rod 106. The driving rod 105 is vertically slidable at one end of the movable slot near the connecting slot. The bottom end of the driving rod 105 is hinged to the other end of the hinge rod 106 slidably along the axis direction of the hinge rod 106. The driving rod 105 is vertically slidable at one end of the movable slot near the connecting slot. The bottom end of the driving rod 105 is hinged to the other end of the hinge rod 106 slidably along the axis direction of the hinge rod 106. 05 is connected to the sealing plate 103, and the return spring 104 is arranged in the movable slot. The two ends of the return spring 104 are respectively connected to one end of the hinged rod 106 and the fermentation chamber 101. Through such an arrangement, when the spray tank 201 is installed on the welding plate 102, the spray tank 201 will press one end of the pressing block 107 extending out of the installation hole, so that the pressing block 107 moves toward the bottom, and then the pressing block 107 presses one end of the hinged rod 106, so that the hinged rod 106 rotates, and then drives the driving rod 105 hinged thereto to move toward the top. Since the driving rod 105 is connected to the sealing plate 103, the sealing plate 103 also moves along with the movement of the driving rod 105, thereby achieving a coordinated relationship between the sealing port of the sealing plate 103 and the communication port. At this time, the permeate in the spray tank 201 can flow into the spray pipe 202 through the communication port. Similarly, when the spray tank 201 falls off, due to the force of the return spring 104, the return spring 104 will drive the hinge rod 106 to reset and rotate, thereby causing one end of the pressing block 107 to extend out of the mounting hole again. The driving rod 105 and the sealing plate 103 will also follow the rotation of the other end of the hinge rod 106 and descend in height, so that the sealing port is no longer in coordinated relationship with the communication port. At this time, the biogas in the fermentation chamber 101 cannot overflow into the external environment through the communication port.It is worth noting that this solution can detect the position of the sealing plate 103 by setting a sensor, and then determine the installation and coordination of the spray tank 201 and the welding plate 102. When it is detected that the spray tank 201 is not installed properly or falls off, it can be detected by the sensor in the first time, and then the spray tank 201 can be reinstalled.

[0031] According to the above embodiment, the function of the permeate in this solution is to react with livestock and poultry manure to form biogas together; however, in actual practice, since the permeate is liquid, as the amount of permeate sprayed into the fermentation chamber 101 increases, the permeate will continue to move toward the bottom, and then flow to the bottom of the livestock and poultry manure, so that in the actual process, only a part of the permeate at the bottom of the livestock and poultry manure reacts with the livestock and poultry manure, while the other part of the permeate is not fully utilized, resulting in waste; based on this, in order to reduce the waste of permeate, a return line is provided at the bottom of the fermentation chamber 101 of this solution. The flow outlet, the spray assembly 2 also includes a filter 206, a return pipe 207 and a return pump 208. The filter 206 is sealed with the surface of the return outlet, and the two ends of the return pipe 207 are respectively connected to the return outlet and the top of the spray tank 201. The return pump 208 is arranged on the side wall outside the fermentation chamber 101, and the return pump 208 is connected to the return pipe 207. Through such an arrangement, when the permeate reaches the bottom of the livestock and poultry manure, the permeate will flow back into the return pipe 207 through the return outlet, and then under the action of the return pump 208, the permeate will flow back into the spray tank 201 and re-participate in the flow. It should be noted that the function of the filter 206 is to prevent the livestock and poultry manure from flowing into the spray tank 201 through the return pipe 207.

[0032] It should also be noted that, since the components of the permeate of this solution are easily destructive to the environment, the permeate is not allowed to overflow into the external environment. Based on this, in order to ensure that the permeate of this solution will not overflow into the external environment even if the spray tank 201 falls off, the spray assembly 2 of this solution also includes a cutoff plate 209, and the fermentation chamber 101 is also provided with a reflux slot hole, which is connected to the reflux port, and the cutoff plate 209 is slidably arranged in the reflux slot hole. A shutoff port is provided, which can lock or release its connection and coordination relationship with the reflux port; by providing a shutoff plate 209, when the shutoff port on the shutoff plate 209 and the reflux port are connected to each other, the permeate in the fermentation chamber 101 can flow back into the spray tank 201 through the reflux port; similarly, when the shutoff port on the shutoff plate 209 and the reflux port are closed to each other, the permeate in the fermentation chamber 101 cannot flow back into the spray tank 201 through the reflux port.

[0033] Furthermore, the spray assembly 2 of this scheme also includes a cutoff spring 210 and a cutoff rod 211. The fermentation chamber 101 and the welding disk 102 are jointly formed with a cutoff slot hole. The two ends of the cutoff slot hole are respectively communicated with the reflux slot hole and the mounting hole. The cutoff spring 210 is arranged in the cutoff slot hole. The two ends of the cutoff spring 210 are respectively connected to the cutoff plate 209 and the fermentation chamber 101. The cutoff rod 211 is slidably arranged in the cutoff slot hole. One end of the cutoff rod 211 is connected to the cutoff plate 209, and the other end can be locked or released from the matching relationship of extending out of the mounting hole. By providing the cutoff rod 211, one end of the cutoff rod 211 extends out of the mounting hole. When the spray tank 201 is installed on the welding disk 102, the spray tank 201 will Pressing the intercepting rod 211 causes it to move, causing one end of the intercepting rod 211 that originally extended out of the mounting hole to shrink into the intercepting slot, thereby driving the intercepting plate 209 connected to the intercepting rod 211 to move, so that the intercepting port on the intercepting plate 209 is connected to the return port. Similarly, when the installed spray tank 201 is detached from the welding plate 102, under the action of the intercepting spring 210, one end of the intercepting rod 211 is re-extended out of the mounting hole, causing the intercepting plate 209 connected to the intercepting rod 211 to move together, thereby causing the intercepting port on the intercepting plate 209 to release its mutual connection with the return port, and the permeate in the fermentation chamber 101 cannot overflow into the external environment through the return port. It is worth noting that in order to ensure that one end of the shut-off rod 211 will shrink into the shut-off slot due to the pressure of the spray tank 201 during the installation of the spray tank 201 on the welding plate 102, the shut-off rod 211 in this solution is tilted at the top of the end close to the mounting hole, and the vertical height of the shut-off rod 211 close to the end of the mounting hole gradually increases along the axial direction of the shut-off rod 211 to the direction of the shut-off plate 209.

[0034] It should be noted that the livestock and poultry manure of this solution is transported into the fermentation chamber 101 by vehicle. In order to facilitate the entry of vehicles into the fermentation chamber 101, the fermentation assembly 1 of this solution also includes a closed door 108. The side wall of the fermentation chamber 101 is provided with a through slot for vehicles carrying livestock and poultry manure to enter and exit. One end of the closed door 108 is hingedly connected to the fermentation chamber 101, and the closed door 108 can be locked or released from its sealing relationship with the through slot. When the closed door 108 is released from its sealing relationship with the through slot, the vehicle loaded with livestock and poultry manure can enter the fermentation chamber 101 and transport the livestock and poultry manure into the fermentation chamber 101.

[0035] According to the above embodiment, this solution is to prevent livestock and poultry manure from entering the reflux port by providing a filter 206. However, in actual operation, the livestock and poultry manure in the fermentation chamber 101 is transported to the fermentation chamber 101 by vehicles. When the vehicle enters the fermentation chamber 101, the tires of the vehicle will press the livestock and poultry manure above the filter 206, so that the livestock and poultry manure above the filter 206 is squeezed into the reflux port due to the pressure, and then enters the spray tank 201 along the reflux pipe 207. Based on this, in order to solve this problem, the fermentation component 1 of the present invention further includes a scraping plate 109, a scraping spring 110 and a pull rope 111. The scraping plate 109 is slidably arranged on the surface of the filter screen 206. The two ends of the scraping spring 110 are respectively connected to the scraping plate 109 and the fermentation chamber 101, and the two ends of the pull rope 111 are respectively connected to the scraping plate 109 and the end of the closing door 108 away from its hinged end. The pull rope 111 is attached to the bottom surface of the fermentation chamber 101, and the bottom surface of the scraping plate 109 and the surface of the filter screen 206 are on the same horizontal plane. The scraping plate 109 can lock or release its mutual communication relationship with the filter screen 206; by providing the scraping plate 109, when the closing door 108 releases its sealing cooperation relationship with the through groove, due to the pull rope 11 1, the scraper plate 109 moves with the opening and closing of the closing door 108, at this time the scraper plate 109 locks its sealing cooperation relationship with the filter 206, and the scraper plate 109 is located on the top of the filter 206. Such an arrangement makes it possible that even if the car presses the livestock and poultry manure located above the filter 206, the livestock and poultry manure will not pass through the filter 206 into the reflux port due to the existence of the scraper plate 109; similarly, after the car pours the livestock and poultry manure into the fermentation chamber 101 and drives out of the fermentation chamber 101, the closing door 108 re-locks its sealing cooperation relationship with the through groove, and due to the force of the scraper spring 110, the scraper plate 109 re-releases its sealing cooperation relationship with the filter 206, and the filter 206 can now work normally. It is worth noting that since the bottom surface of the scraper plate 109 of this solution is on the same horizontal plane as the surface of the filter screen 206, when the scraper plate 109 gradually moves to the surface of the filter screen 206, the scraper plate 109 will scrape off the livestock and poultry manure attached to the surface of the filter screen 206, so that the subsequent permeate can smoothly pass through the filter screen 206 and enter the reflux port, ensuring the normal operation of the device.
