Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of sludge treatment, and in particular to a sludge drying and incineration treatment device and a treatment method. Background Art
[0002] With the development of social economy and the improvement of people's living standards, the output of industrial wastewater and urban sewage is increasing. In the process of sewage treatment, a large amount of suspended matter will be generated. These substances are collectively called sludge. The composition of sludge is relatively complex. If it is piled up arbitrarily, it will have a great impact on the health of humans, animals and plants. Therefore, a sludge drying and incineration treatment device is needed to dry and incinerate the sludge.
[0003] A Chinese patent discloses a sludge drying and incineration integrated treatment device (authorization announcement number CN217921799U). This patented technology uses a first motor, a second hollow shaft, and a wedge-shaped hollow blade to allow the first motor to drive the internal second hollow shaft to rotate, and ultimately drive the wedge-shaped hollow blade to rotate, so that the sludge material inside the sludge drying treatment body is dried uniformly to avoid the problem of uneven heating area. However, the stirring method of this device is relatively simple and cannot fully increase the contact area between the sludge and the hot air flow, resulting in slow water evaporation, a long drying cycle, and a large amount of energy consumption. Moreover, due to the lack of effective wind penetration, the internal heat exchange of the sludge is insufficient, and local incomplete drying is very likely to occur, which not only affects subsequent treatment, but may also cause secondary pollution;
[0004] A Chinese patent discloses a circulating sludge drying and incineration device (authorization announcement number CN212051040U). This patented technology starts a servo motor and uses the servo motor to drive the screw rod to rotate, which not only improves the sludge drying efficiency, but also crushes the dried sludge. After the sludge is dried and crushed, the valve on the discharge pipe is opened to introduce the dried and crushed sludge into the incinerator. This not only does not require manual placement of the dried sludge in the incinerator, thereby reducing labor intensity, but lacks an accurate quantitative conveying mechanism when conveying the dried sludge to the incinerator, and the sludge cannot be stably conveyed from the stirring link to the drying furnace. This causes large fluctuations in the working conditions in the drying furnace, making it difficult to ensure consistent drying effects, which seriously affects the drying efficiency.
[0005] In the sludge treatment and transportation to incineration in the drying furnace, many devices fail to reasonably design the sludge residence time and movement path, and cannot fully turn the sludge during transportation, which ultimately leads to the sludge after drying having a high moisture content, increasing the difficulty and cost of subsequent incineration treatment.

[0042] Example 1
[0043] See also Figure 1-Figure 5 As shown, one of the purposes of this embodiment is to provide a sludge drying and incineration treatment device, including a bracket 1, the upper side of the bracket 1 is movably connected to a base 14, the upper side of the base 14 is provided with a stirring furnace 11, the upper and lower sides of the stirring furnace 11 are respectively provided with a feed port and a discharge port, the stirring furnace 11 and the drying furnace 12 are connected near the lower side through a control device 3, the control device 3 is arranged inside the base 14, the drying furnace 12 is provided with an auxiliary device 4, the stirring furnace 11 is provided with a stirring device 2, and the control device 3 is arranged below the stirring device 2;
[0044] The sludge after preliminary dehydration is transported to the stirring furnace 11, and a hot air flow is transported to the interior of the stirring furnace 11 through the air inlet 17. The stirring device 2 stirs the sludge inside the stirring furnace 11, and the stirred sludge contacts the hot air flow. The stirring device 2 guides the external air flow into the sludge while stirring the sludge. A control device 3 is provided inside the base 14. The stirred sludge falls into the base 14 through the discharge port. The control device 3 rotates to transport the sludge in the base 14 to the inside of the drying furnace 12 in a quantitative manner. The control device 3 drives the auxiliary device 4 to rotate when rotating, and the auxiliary device 4 transports the sludge inside the drying furnace 12 upward to the inside of the incinerator 13 for incineration.
[0045] See also Figure 1-Figure 5 As shown, the outer walls of the stirring furnace 11 and the base 14 are provided with a drying furnace 12, the outer wall of the drying furnace 12 is provided with an incinerator 13, and the central axes of the stirring furnace 11, the drying furnace 12 and the incinerator 13 are in the same straight line, and a plurality of air inlets 17 are provided on the side wall of the stirring furnace 11, and a feed port and a discharge port are provided on the upper and lower sides of the stirring furnace 11 respectively. When using this device, the sludge after preliminary dehydration is transported to the stirring furnace 11. Since the drying furnace 12 is provided on the outside of the stirring furnace 11, the inside of the drying furnace 12 dries the sludge, so the temperature inside the drying furnace 12 can transport hot air to the inside of the stirring furnace 11 through the air inlet 17.
[0046] See also Figure 4 and Figure 5The stirring device 2 includes a servo motor 24 fixedly connected to the upper end of the bracket 1, and the output end of the servo motor 24 is fixedly connected to the rotating shaft 21. The lower end of the rotating shaft 21 passes through the upper end of the bracket 1 and extends to the interior of the stirring furnace 11. The outside of the rotating shaft 21 is fixedly connected to a stirring tube 22, and the upper end of the stirring tube 22 extends to the upper end of the stirring furnace 11. The outside of the stirring tube 22 is fixedly connected to multiple groups of stirring blades 23. Then start the servo motor 24 to drive the rotating shaft 21 to rotate, and the rotation of the rotating shaft 21 drives the stirring tube 22 to rotate, and the stirring tube 22 drives multiple stirring blades 23 to rotate. The stirring blades 23 rotate to stir the sludge inside the stirring furnace 11, and the stirred sludge contacts the hot air flow, increasing the contact area between the sludge and the hot air flow, so that the moisture in the sludge is more quickly and fully carried away by the hot air flow, thereby accelerating the drying speed of the sludge.
[0047] See also Figure 5 and Figure 6 The lower sides of multiple groups of stirring blades 23 are fixedly connected with air outlet holes 26. Multiple groups of stirring blades 23 are arranged in an arc shape, and the surface of the stirring blades 23 facing the upper end of the stirring furnace 11 is an arc surface. There are three stirring blades 23 in a circular array in each group, and the two groups of rotating shafts 21 are staggered between adjacent groups. When the stirring blades 23 rotate, the stirring blades 23 tilt downward. During the rising process of the hot air inside the stirring furnace 11, the hot air is blocked by the arc surface of the stirring blades 23, and the hot air moves horizontally in the stirring furnace 11, preventing the hot air from flowing upward quickly and dissipating quickly.
[0048] See also Figure 4 and Figure 9 As shown, two inclined plates 27 are fixedly connected to the interior of the stirring furnace 11, and the middle position of the inclined plate 27 extends toward the lower end of the stirring furnace 11. The two inclined plates 27 divide the interior of the stirring furnace 11 into multiple spaces, and each group of stirring blades 23 is arranged inside the space. The lower end of the inclined plate 27 is tilted downward to form an arc surface. Several inclined plates 27 cooperate with each other to divide the interior of the stirring furnace 11 into multiple spaces. Multiple spaces can be used to stir and dry sludge at different levels. At the same time, the inclined plates 27 and the stirring blades 23 form an interlaced structure. During the rising process, the hot air extends the moving speed of the hot air inside the stirring furnace 11, so that the hot air can continuously and fully contact the sludge.
[0049] See also Figure 2-Figure 5As shown, the upper end of the rotating shaft 21 is fixedly connected to the rotating wheel 25, and the upper end of the bracket 1 is fixedly connected to the sleeve 231. The outer circumferential array of the sleeve 231 has several through holes. The interior of the sleeve 231 is rotatably connected to the rotating wheel 25. The interior of the rotating wheel 25 is fixedly connected to the upper end of the rotating shaft 21, and the interior of the stirring blade 23 is communicated with the interior of the stirring tube 22. The rotating shaft 21 drives the rotating wheel 25 to rotate while rotating. The rotating wheel 25 rotates to transport the external wind force through the sleeve 231 to the interior of the stirring tube 22, and then transport it from the interior of the stirring tube 22 to the interior of the stirring blade 23, and blow it out from the air outlet 26, so that the stirring blade 23 blows air to the sludge while stirring, so that the wind can penetrate into the sludge, promote heat exchange and water evaporation between sludge particles, make the sludge drying more uniform, and avoid the occurrence of incomplete local drying.
[0050] See also Figure 4 and Figure 5 as well as Figure 9 and Figure 10 As shown, the control device 3 includes two discharge ports opened on the upper side of the base 14 and adapted to the discharge port, the lower end of the stirring furnace 11 and the lower end of the drying furnace 12 are fixedly connected with an arc plate 35, the inner part of the base 14 is rotatably connected with a cylindrical rod 31, the upper end of the cylindrical rod 31 is fixedly connected with two fixed plates 32, and two discharge ports 33 extending downward are fixedly provided on the two fixed plates 32, and the discharge port 33 on the upper fixed plate 32 is slidably inserted into the discharge port 33 on the lower fixed plate 32, and the sealing plate 3 is rotatably connected to the adjacent side of the two discharge ports 33 at the bottom. 4. A round ball is provided at one end of the sealing plate 34. The surface of the round ball fits with the lower end of the top plate 36. When the sealing plate 34 rotates, the round ball is driven to roll frictionally on the lower side of the top plate 36. The diameter of the sealing plate 34 is larger than the diameter of the discharge port 33. The lower end of the bracket 1 is fixedly connected to the driving motor. The output end of the driving motor is fixedly connected to the fixing rod 382. The output end of the fixing rod 382 is rotatably connected to the lower end of the top plate 36. The upper end of the fixing rod 382 is fixedly connected to the half gear 381. The lower end of the cylindrical rod 31 is fixedly connected to the spur gear 38. The spur gear 38 is meshed with the half gear 381.
[0051] After the sludge is stirred, it enters the discharge port 33 through the discharge port, and the driving motor is started to drive the fixed rod 382 to rotate. The fixed rod 382 drives the half gear 381 to rotate, and the half gear 381 is meshed with the spur gear 38 for transmission, thereby driving the cylindrical rod 31 to rotate. The rotation of the cylindrical rod 31 drives the spiral frame 41 to rotate. When the cylindrical rod 31 rotates, it drives the two fixed plates 32 to rotate. When the fixed plate 32 at the bottom rotates, it drives the sealing plate 34 to rotate, so that one end of the sealing plate 34 slides along the lower end of the top plate 36. When the half gear 381 rotates to no longer mesh with the spur gear 38, the sealing plate 34 on the left side rotates along the lower edge of the top plate 36 to the position of the oblique mouth 361. At this time, the sealing plate 34 rotates. The mixing furnace 11 is moved to an inclined state, and the sludge inside the discharge port 33 flows into the interior of the drying furnace 12 through the curved plate 35, and the other sealing plate 34 is rotated to a horizontal state along the lower end edge of the top plate 36, blocking the lower end of the discharge port 33, so that the sludge inside the stirring furnace 11 flows into the interior of the discharge port 33, preparing for the next batch of sludge transportation. The two fixed plates 32 are intermittently rotated to transport the sludge in the stirring furnace 11 to the interior of the drying furnace 12 in a quantitative manner, which can stabilize the sludge processing capacity in the drying furnace 12, so that the drying process is carried out under relatively stable working conditions, ensuring the consistency of the drying effect; at the same time, it is avoided that the normal operation and drying efficiency of the drying furnace 12 are affected by excessive or insufficient sludge transportation.
[0052] See also Figure 9 and Figure 10 As shown, several electric telescopic rods 37 are fixedly connected to the interior of the base 14, and the upper ends of the several electric telescopic rods 37 are fixedly connected to the top plate 36, and the top plate 36 is arranged below the fixed plate 32, and the lower end of the top plate 36 is in contact with one end of the sealing plate 34. The lower end of the top plate 36 is provided with an oblique opening 361. When the electric telescopic rod 37 is started to move upward, the electric telescopic rod 37 drives the top plate 36 to move upward, and the upward movement of the top plate 36 drives the fixed plate 32 located below to move upward synchronously, thereby reducing the distance between the two fixed plates 32, thereby controlling the capacity of the sludge inside the discharge port 33.
[0053] See also Figure 3 and Figure 8As shown, the auxiliary device 4 includes a spiral frame 41 fixedly connected to the outside of the base 14, the spiral frame 41 is arranged between the stirring furnace 11 and the drying furnace 12, and a plurality of baffles 42 are fixedly connected to the upper side of the spiral frame 41, and the plurality of baffles 42 are inclined toward the upper end of the spiral frame 41. A notch 43 is provided near the upper end of the drying furnace 12, and the notch 43 connects the drying furnace 12 and the incinerator 13. An air outlet 16 is provided at the upper end of the incinerator 13. When the sludge enters the interior of the drying furnace 12, the base 14 rotates to drive the spiral frame 41 to rotate, and the spiral frame 41 rotates. The sludge inside the drying furnace 12 is transported upward, and the baffle 42 blocks the sludge to ensure the stability of the sludge during the transportation process. The spiral rack 41 drops the dried sludge from the gap 43 above to the inside of the incinerator 13 for incineration. Through the setting of the spiral rack 41, the sludge can be lifted and transported in an orderly manner, so that the sludge has a suitable residence time and movement path in the drying furnace 12, which increases the drying time of the sludge in the drying furnace 12 and facilitates the drying process; and the rotation of the spiral rack 41 can turn the sludge again to further enhance the drying effect.
[0054] When the sludge drying and incineration treatment device and treatment method of the present invention are used, the sludge after preliminary dehydration is first transported to the stirring furnace 11, and a hot air flow is transported to the interior of the stirring furnace 11 through the air inlet 17. The rotating shaft 21 rotates to drive the stirring tube 22 to rotate, and the stirring tube 22 drives multiple stirring blades 23 to rotate to stir the sludge inside the stirring furnace 11. The stirred sludge contacts the hot air flow, increasing the contact area between the sludge and the hot air flow, so that the moisture in the sludge is more quickly and fully carried away by the hot air flow, thereby accelerating the drying speed of the sludge. The rotating shaft 21 rotates while driving the rotating wheel 25 to rotate. The rotating wheel 25 rotates to transport external wind force through the sleeve 231 to the interior of the stirring tube 22, and then to the interior of the stirring blade 23 and blown out from the air outlet 26, so that the stirring blade 23 blows air to the sludge while stirring, so that the wind can penetrate into the interior of the sludge, promote heat exchange and water evaporation between sludge particles, make the sludge drying more uniform, and avoid the occurrence of incomplete local drying.
[0055] After the sludge is stirred, it enters the discharge port 33 through the discharge port and is driven by the driving motor to rotate the half gear 381. The half gear 381 meshes with the spur gear 38 for transmission, thereby driving the cylindrical rod 31 to rotate. The rotation of the cylindrical rod 31 drives the spiral frame 41 to rotate. When the cylindrical rod 31 rotates, it drives the two fixed plates 32 to rotate. When the fixed plate 32 located below rotates, it drives the sealing plate 34 to rotate, so that one end of the sealing plate 34 slides along the lower end of the top plate 36. When the half gear 381 rotates and cooperates with the spur gear 38, the fixed plate 32 and the sealing plate 34 rotate intermittently, and the sludge in the stirring furnace 11 is quantitatively transported to the interior of the drying furnace 12, which can stabilize the sludge processing capacity in the drying furnace 12, so that the drying process can be carried out under relatively stable working conditions, ensuring the consistency of the drying effect, and at the same time avoiding the normal operation and drying efficiency of the drying furnace 12 being affected by excessive or insufficient sludge transportation.
[0056] When the sludge enters the interior of the drying furnace 12, the rotation of the base 14 drives the spiral frame 41 to rotate. The rotation of the spiral frame 41 transports the sludge inside the drying furnace 12 upward. The baffle 42 blocks the sludge to ensure the stability of the sludge during transportation. The spiral frame 41 drops the dried sludge from the gap 43 above to the interior of the incinerator 13 for incineration. Through the setting of the spiral frame 41, the sludge can be lifted and transported in an orderly manner, so that the sludge has a suitable residence time and movement path in the drying furnace 12, which increases the drying time of the sludge inside the drying furnace 12 and facilitates the drying process; and the rotation of the spiral frame 41 can turn the sludge again, further enhancing the drying effect.
[0057] The second purpose of this embodiment is to provide a sludge treatment method for operating the above-mentioned sludge drying and incineration treatment device, comprising the following steps:
[0058] S1. First, the preliminarily dehydrated sludge is transported to the stirring furnace 11. A hot air flow is transported to the interior of the stirring furnace 11 through the air inlet 17. The stirring device 2 stirs the sludge inside the stirring furnace 11.
[0059] S2, the stirred sludge then falls into the base 14 through the discharge port, and the control device 3 rotates to quantitatively transport the sludge in the base 14 into the drying furnace 12 for drying;
[0060] S3. The control device 3 drives the auxiliary device 4 to rotate while rotating, and the auxiliary device 4 transports the sludge inside the drying furnace 12 upward to the inside of the incinerator 13 for incineration.
