Description

Technical Field

[0001] The present application relates to the technical field of sludge treatment, and in particular to a spray defoaming device for a sludge anaerobic digestion reactor. Background Art

[0002] The anaerobic sludge digestion reactor is a highly efficient device for treating sludge. Through the action of anaerobic microorganisms, it converts organic matter in the sludge into energy sources such as biogas, while simultaneously stabilizing and reducing the sludge volume. During the reaction, foam is generated, which can affect the stable operation of the anaerobic digestion system and even fill the gas phase and enter the biogas pipeline, causing operational difficulties. Spray defoaming can quickly reduce the amount of foam and maintain smooth system operation.

[0003] Existing spraying equipment is usually fixedly installed, with a limited spraying range, resulting in low defoaming efficiency. In addition, during the spraying process, the distance between the spraying equipment and the foam may be too close or too far, affecting the normal sludge treatment efficiency.

[0020] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, they are further elaborated below in conjunction with specific implementation methods.

[0021] A spray defoaming device for sludge anaerobic digestion reactor, see Figures 1 to 3 , including a reactor body 1, a main water pipe 8, an annular slider 602 and a fixing bolt 7. The top center of the reactor body 1 is fixedly connected to a fixing frame 2, and the top center of the fixing frame 2 is fixedly connected to an annular slide groove 5. The annular slider 602 is located on the inner side of the annular slide groove 5 and is slidably connected to the annular slide groove 5, and the top of the annular slider 602 is fixedly connected to a rotating disk 6. The bottom end of the main water pipe 8 passes through the rotating disk 6, the fixing frame 2 and the center of the surface of the reactor body 1 from above, and a number of bolt holes 9 are evenly opened vertically on the side walls of the main water pipe 8. The fixing bolt 7 passes through the top protrusion of the rotating disk 6 horizontally and is threadedly connected to the main water pipe 8 through the bolt hole 9. When adjusting the main water pipe 8, first unscrew the fixing bolt 7, then adjust the upper and lower positions of the main water pipe 8, align the corresponding bolt holes 9, and then re-tighten the fixing bolt 7, thereby changing the distance between the branch pipe 801 and the spray head 802 and the foam, adapting to the positions of different foams, and improving the spraying efficiency.

[0022] At the same time, a tooth groove 601 is provided on the outer wall of the rotating disk 6, and the top surface of the fixed frame 2 on one side of the rotating disk 6 is rotatably connected to the driving gear 4, and the driving gear 4 is engaged with the tooth groove 601. When spraying, the driving gear 4 rotates under the drive of the servo motor 3 below, thereby causing the rotating disk 6 and the annular slider 602 to rotate in the annular chute 5, and further driving the main water pipe 8 and the branch pipe 801 to rotate, so that spraying is performed during rotation, and the spraying can be more uniform.

[0023] Specifically, such as Figure 2 As shown, the bottom end of the main water pipe 8 is connected to a number of branch pipes 801, and a number of spray heads 802 are evenly opened on the bottom surface of the branch pipe 801. One end of the branch pipe 801 is connected to the main water pipe 8, and the other end is located on the side of the inner wall of the reactor body 1, but does not contact the inner wall of the reactor body 1, so as to facilitate rotation, and the number of spray heads 802 is large, thereby increasing the density of the spray.

[0024] It is worth noting that if Figure 3 As shown, a sealing ring 11 is fixedly connected to the inner wall of the reactor body 1 at the position where the main water pipe 8 passes through. The sealing ring 11 can seal the position where the main water pipe 8 passes through, thereby avoiding gas leakage as much as possible.

[0025] It is worth noting that if Figure 3 As shown, a servo motor 3 is fixedly connected to the top of the fixed frame 2 just below the driving gear 4, and the tail end of the transmission shaft of the servo motor 3 is fixedly connected to the driving gear 4. After adjustment, the servo motor 3 rotates at a slower speed, which facilitates more uniform spraying.

[0026] It is worth noting that if Figure 3 As shown, the main water pipe 8 is perpendicular to the surface of the fixed frame 2 and fits the rotating disk 6 , thereby making the rotation process more stable and preventing the branch pipe 801 from hitting the inner wall of the reactor body 1 .

[0027] It is worth noting that if Figure 3 As shown, the top end of the main water pipe 8 is movably connected to a rotary joint 10, which can rotate to prevent the main water pipe 8 from twisting against the external water pipe when rotating.

[0028] In actual use, the top of the main water pipe 8 is connected to the external water pipe for water supply, and the water flows downward along the water injection pipe to the branch pipe 801, and is finally sprayed out from the spray head 802, thereby spraying the foam. During spraying, the active gear 4 rotates under the drive of the servo motor 3 below, so that the rotating disk 6 and the annular slider 602 rotate in the annular slide 5, further driving the main water pipe 8 and the branch pipe 801 to rotate, thereby spraying during rotation, which can spray more evenly and improve the efficiency of defoaming; the main water pipe 8 can move up and down to adjust the distance between the branch pipe 801 and the foam. When adjusting, first unscrew the fixing bolt 7, and then adjust the up and down position of the main water pipe 8, align the corresponding bolt holes 9, and then re-tighten the fixing bolt 7, thereby changing the distance between the branch pipe 801 and the spray head 802 and the foam, adapting to the position of different foams, improving the spraying efficiency, and maximizing the spraying effect.

[0029] In addition, the components designed in this utility model are all universal standard parts or components known to technical personnel in this field. Their structures and principles can be known to technical personnel through technical manuals or through conventional experimental methods. They can be fully implemented by technical personnel in this field. Needless to say, the content protected by this utility model does not involve improvements to internal structures and methods.

[0030] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
