Description

Technical Field

[0001] The present application relates to the technical field of sludge treatment equipment, and particularly to a sludge anaerobic digestion treatment system. Background Art

[0002] The rapid development of urbanization has led to a sharp increase in sludge emissions. In order to improve the level of sludge anaerobic treatment in China, make full use of the energy recovery from sludge, and improve the characteristics of sludge, China has listed the sludge anaerobic digestion treatment technology as an emerging industry to be vigorously cultivated and developed.

[0003] Sludge anaerobic digestion refers to a digestion technology in which sludge is decomposed by various bacteria to decompose the organic matter in the sludge into CH4, CO2, H2O, and H2S. As the organic matter in the sludge decomposes, the large amount of high-calorific value gas generated can be reused as energy, that is, the sludge is treated resourcefully. This technology is a common means for sludge reduction and stabilization, and is also a more economical sludge treatment method adopted by large sewage treatment plants.

[0004] During the process of sludge anaerobic digestion treatment, in order to decompose the organic matter in the sludge, a bacterial agent (i.e., containing facultative bacteria or anaerobic bacteria, or a mixed bacterial agent) needs to be added to the sludge. Usually, when adding the bacterial agent to the sludge, only the bacterial agent is simply added, and the degree of uniformity of the mixture of the sludge and the bacterial agent needs to be further improved in order to fully decompose the organic matter in the sludge and improve the energy recovery efficiency of the sludge. Summary of the Invention

[0005] In order to improve the degree of uniformity of the mixture of the sludge and the bacterial agent, the present application provides a sludge anaerobic digestion treatment system.

[0006] A sludge anaerobic digestion treatment system provided by the present application adopts the following technical solution:

[0007] A sludge anaerobic digestion treatment system includes a treatment tank. A treatment chamber for degrading the organic matter in the sludge is provided in the treatment tank. A feed pipe is installed on the treatment tank, and the feed pipe communicates with the treatment chamber. A bacterial agent pipe is installed on the feed pipe, and the bacterial agent pipe communicates with the feed pipe. A diversion cone for diverting the sludge is provided in the bacterial agent pipe. A dispersion cone is installed on the bacterial agent pipe. A dispersion chamber is provided in the dispersion cone, and the dispersion chamber communicates with the bacterial agent pipe. A bacterial agent tray for dispensing the bacterial agent is installed on the dispersion cone, and the bacterial agent in the bacterial agent tray enters the bacterial agent pipe through the dispersion chamber.

[0008] Through the above technical solution, after the operator puts the sludge into the inoculant tube and places the inoculant into the inoculant tray, under the diversion of the diversion cone, the sludge flows downward along the outer surface of the diversion cone, increasing the contact area of the sludge. The inoculant flows into the inoculant tube along the inoculant tray and the dispersion chamber, enabling the inoculant to be fully mixed with the sludge after the contact area is increased, thereby improving the uniformity of the mixture of the sludge and the inoculant, which is beneficial to the full degradation of the organic matter in the sludge by the inoculant.

[0009] In a preferred example of the present application, it can be further configured that: the diversion cone is slidably installed in the inoculant tube along the length direction of the inoculant tube, a driving rod is installed on the diversion cone, and a sliding groove one for the driving rod to slide is opened on the inoculant tube.

[0010] Through the above technical solution, the operator can reciprocally slide the driving rod along the length direction of the inoculant tube, and the driving rod drives the diversion cone to slide along the length direction of the inoculant tube, so that the sludge in the inoculant tube can be dredged by the diversion cone.

[0011] In a preferred example of the present application, it can be further configured that: a closing plate for closing the sliding groove one is installed on the driving rod, a sliding groove two for the closing plate to slide is opened in the inoculant tube, and the sliding groove two communicates with the sliding groove one.

[0012] Through the above technical solution, during the sliding of the diversion cone, since the closing plate is located on the driving rod, the closing plate can follow the driving rod to slide. Under the closing action of the closing plate, the sliding groove one can be continuously closed, reducing the possibility of the sludge in the inoculant tube overflowing outward along the sliding groove one.

[0013] In a preferred example of the present application, it can be further configured that: the inoculant tube includes a half tube one and a half tube two, the half tube one is detachably connected to the half tube two through a bolt one, the half tube two is detachably connected to the feeding tube through a flange, and the driving rod is detachably connected to the diversion cone through a bolt two.

[0014] Through the above technical solution, when the operator needs to digest sludge with different viscosities, first stop the sludge injection, and then release the connections of the flange, bolt one, and bolt two, so as to facilitate the operator to replace the diversion cones with different sizes (radius and length), enabling the sludge to flow smoothly into the feeding tube, that is, the replaced diversion cone can be suitable for the diversion of sludge with different viscosities, thereby improving the applicable range of the equipment.

[0015] In a preferred embodiment, the present application can be further configured as follows: A compaction plate is slidably installed in the processing chamber. An installation plate is provided on the processing tank, and an electric push rod for driving the compaction plate to slide in the processing chamber is installed on the installation plate. One end of the driving rod away from the diversion cone is fixedly connected to the compaction plate.

[0016] Through the above technical solution, when the sludge in the processing tank accumulates to a certain height, by starting the electric push rod, on the one hand, the piston rod of the electric push rod pushes the compaction plate downward, so that the sludge in the processing chamber is compacted. On the other hand, during the telescopic movement of the piston rod of the electric push rod, the driving rod and the diversion cone can reciprocate with the compaction plate, so as to facilitate the dredging of the sludge in the inoculant pipe through the diversion cone.

[0017] In a preferred embodiment, the present application can be further configured as follows: An air collecting cylinder is provided on the installation plate, and a collecting pipe is installed on the compaction plate. The air collecting cylinder is communicated with the processing chamber through the collecting pipe.

[0018] Through the above technical solution, after the inoculant and the sludge are mixed and enter the processing chamber, the inoculant degrades the organic matter in the sludge, and the high calorific value gas generated during the degradation process can enter the air collecting cylinder along the collecting pipe, thus completing the collection of the high calorific value gas.

[0019] In a preferred embodiment, the present application can be further configured as follows: A sliding groove three is formed in the compaction plate, and a blocking plate for blocking the collecting pipe is slidably installed in the sliding groove three. A lead screw is rotatably installed in the compaction plate, and the blocking plate is threadedly connected to the lead screw.

[0020] Through the above technical solution, during the downward movement of the compaction plate, by rotating the lead screw, the lead screw drives the blocking plate to move towards the collecting pipe, so that the blocking plate blocks the collecting pipe, reducing the possibility of the collecting pipe being blocked by sludge. Vice versa, during the upward movement of the compaction plate, by rotating the lead screw, the blocking plate is driven to move away from the collecting pipe, releasing the blockage of the collecting pipe by the blocking plate, so as to facilitate the gas to enter the air collecting cylinder through the collecting pipe.

[0021] In a preferred example, the present application can be further configured as follows: a rotating shaft is rotatably installed on the compaction plate, a sleeve is rotatably installed on the electric push rod, the rotating shaft is slidably installed in the sleeve, a limiting strip is installed on the sleeve, a limiting groove for the limiting strip to slide is provided on the inner wall of the sleeve, a first bevel gear and a second bevel gear are rotatably installed in the compaction plate, the first bevel gear and the second bevel gear are meshed with each other, the first bevel gear is installed on the rotating shaft, the second bevel gear is installed on the lead screw, a spur gear is rotatably installed on the mounting plate, a rack is installed on the piston rod of the electric push rod, the rack and the spur gear are meshed with each other, a third bevel gear is installed on the sleeve, a fourth bevel gear is installed on the spur gear, and the fourth bevel gear and the third bevel gear are meshed with each other.

[0022] Through the above technical solution, during the process of the piston rod of the electric push rod pushing the compaction plate downward, the rack on the piston rod drives the spur gear to rotate, the spur gear drives the fourth bevel gear to rotate, the fourth bevel gear drives the third bevel gear to rotate, the third bevel gear drives the sleeve to rotate, the sleeve drives the rotating shaft to rotate through the limiting strip, the rotating shaft drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, the second bevel gear drives the lead screw to rotate, and the lead screw drives the blocking plate to move towards the collecting pipe, thereby completing the blocking of the collecting pipe by the blocking plate.

[0023] Conversely, during the process of the piston rod of the electric push rod pushing the compaction plate upward, through the rack, spur gear, fourth bevel gear, third bevel gear, sleeve, rotating shaft, first bevel gear, second bevel gear and lead screw, the blocking plate is driven to move away from the collecting pipe to release the blocking of the collecting pipe by the blocking plate.

[0024] In a preferred example, the present application can be further configured as follows: a first temperature control cavity and a second temperature control cavity are provided in the treatment tank, and the treatment cavity is located between the first temperature control cavity and the second temperature control cavity.

[0025] Through the above technical solution, the operator can inject a liquid with an appropriate temperature (such as hot water) into the first temperature control cavity and the second temperature control cavity to improve the activity of the bacteria in the bactericide, so as to accelerate the degradation rate of the organic matter in the sludge by the bactericide. In addition, since the treatment cavity is located between the first temperature control cavity and the second temperature control cavity, the heating area of the sludge in the treatment cavity is increased, thereby further improving the degradation rate of the organic matter in the sludge by the bactericide.

[0026] In a preferred example, the present application can be further configured as follows: the first temperature control cavity and the second temperature control cavity are communicated with each other.

[0027] Through the above technical solution, since the first temperature control cavity and the second temperature control cavity are communicated with each other, the operator does not need to add hot water to the first temperature control cavity and the second temperature control cavity respectively in sequence, which improves the efficiency of the operator adding hot water into the first temperature control cavity and the second temperature control cavity.

[0028] In summary, the present application includes the following beneficial technical effects:

[0029] 1. The bacterial agent and the sludge after flow splitting are fully mixed, thereby improving the uniformity of the mixing of the sludge and the bacterial agent, which is beneficial to the full degradation of the organic matter in the sludge by the bacterial agent;

[0030] 2. The operator can replace the flow splitting cones of different sizes, enabling the sludge to smoothly flow into the feed pipe, thus expanding the applicable range of the equipment;

The operator disconnects the connections of the flange 223, the first bolt 211, and the second bolt 33 to facilitate the replacement of the flow dividing cone 3 with different sizes, so that the sludge can smoothly flow into the feeding pipe 12 and the treatment chamber 11, that is, the replaced flow dividing cone 3 can be suitable for the sludge diversion with different viscosities, thereby improving the applicable range of this equipment.

[0050] Refer to the attached Figure 3 As shown in the figure, a compaction plate 13 is slidably installed in the treatment chamber 11 along the vertical direction. The cross section of the compaction plate 13 is circular. Two vertically arranged electric push rods 15 are fixedly connected to the bottom surface of the mounting plate 14.

During the telescopic process of the piston rod 151 of the electric push rod 15, the driving rod 31 and the flow dividing cone 3 can move reciprocally following the compaction plate 13, so as to facilitate the dredging of the sludge in the bacterial agent pipe 2 through the flow dividing cone 3.

[0051] Refer to the attached Figure 3 As shown in the figure, one end of the collection pipe 161 far from the air collection cylinder 16 is installed on the compaction plate 13. A third sliding groove 131 is formed in the compaction plate 13 along the horizontal direction.

A limiting groove 61 for the limiting strip 51 to slide is formed on the inner wall of the sleeve 6. A connecting rod 141 is fixedly connected to the bottom surface of the mounting plate 14. A spur gear 17 is rotatably installed on the connecting rod 141. A rack 152 is fixedly connected to the piston rod 151 of the electric push rod 15.

A fourth bevel gear 171 is coaxially and fixedly connected to the spur gear 17. The fourth bevel gear 171 and the third bevel gear 62 are meshed with each other.

[0054] During the process of the piston rod 151 of the electric push rod 15 pushing the compaction plate 13 downward, on the one hand, the compaction plate 13 can compact the sludge; on the one hand, the compaction plate 13 drives the diversion cone 3 to slide inside the inoculant tube 2 through the driving rod 31 to dredge the sludge inside the inoculant tube 2; on the other hand, the rack 152 on the piston rod 151 drives the spur gear 17 to rotate. The spur gear 17 drives the sleeve 6 to rotate through the fourth bevel gear 171 and the third bevel gear 62. The sleeve 6 drives the rotating shaft 5 to rotate through the limiting strip 51. The rotating shaft 5 drives the lead screw 133 to rotate through the first bevel gear 52 and the second bevel gear 134. The lead screw 133 drives the plugging plate 132 to move towards the direction close to the collecting pipe 161, so as to complete the plugging of the collecting pipe 161 by the plugging plate 132, thereby reducing the possibility of sludge blocking the collecting pipe 161.

[0055] The implementation principle of this embodiment is as follows: After the operator puts the sludge and the inoculant into the inoculant tube 2 and the inoculant tray 42 respectively, under the diversion action of the diversion cone 3, the sludge flows downward along the outer surface of the diversion cone 3, increasing the contact area of the sludge. The inoculant enters the inoculant tube 2 through the dispersion cavity 41 and is mixed with the diverted sludge, improving the uniformity of the mixing of the sludge and the inoculant, thereby facilitating the full degradation of the organic matter in the sludge by the inoculant.

[0056] During the process of organic matter degradation in the sludge, hot water is injected into the first temperature control chamber 101 and the second temperature control chamber 102 through the water inlet pipe 103 to enhance the activity of the bacteria in the bacterial agent, so as to accelerate the degradation rate of the organic matter in the sludge by the bacterial agent. The high calorific value gas generated by the degradation of the organic matter in the sludge enters the gas collecting cylinder 16 along the collecting pipe 161, thus completing the collection of the high calorific value gas.

[0057] After the degradation of the organic matter in the sludge is completed, the sludge is discharged through the discharge port.
