Description

[0002] As my country's urbanization gradually develops and improves, sewage treatment facilities are increasingly improved, and the demand for sludge treatment is also gradually increasing. In order to improve the efficiency of sludge treatment and increase the resource utilization of sludge, treatment technologies such as ultrasound, digestion, electric field and oxidation have been promoted and applied. However, the sewage treatment plants currently in operation in my country generally have insufficient carbon sources and imbalanced C / N values, which have affected the denitrification and phosphorus removal efficiency of the system. In order to ensure the efficiency of denitrification and phosphorus removal, it is a common method to use the residual sludge in the sewage treatment process to supplement the carbon source. That is, by destroying the microbial cells in the sludge, the organic carbon source in the contents is dissolved. This treatment method not only increases the carbon source of the influent, which is conducive to the anaerobic digestion reaction of microorganisms, but also properly addresses the disposal dilemma of the huge amount of residual sludge production and significantly reduces the pressure of sludge treatment.

The cross-sectional shape of the metal straight tube 15 is a regular polygon or a circle, that is, the cross-sectional shape of the metal straight tube 15 can be a regular quadrilateral, a regular pentagon, a regular hexagon, a regular dodecagon, or a circle. When the design is enlarged, the multi-layer flow channel can ensure a compact structure and sufficient electric field strength. At the same time, the effective space utilization rate of the flow channel of the metal straight tube 15 is not less than 50%. Specifically, the effective space utilization rates of the flow channel of the metal straight tube 15 are 63.69% for a regular quadrilateral, 50.14% for a regular pentagon, 82.74% for a regular hexagon, 78.85% for a regular dodecagon, and 77.78% for a circle. Regular hexagonal metal straight tubes are preferred.

When using diameters of φ16mm and φ20mm, the recommended spacing between the wall of the metal straight tube 15 and the center of the cylindrical insulated electrode rod 5 is between 15-20mm. When using a diameter of φ40mm, the corresponding spacing is recommended to be between 30-35mm to ensure the electric field strength and space utilization requirements. The outer diameter of the cylindrical insulated electrode rod 5 is usually φ16, φ20 or φ40 mm, etc., and the spacing on the matching regular hexagonal metal straight tube is usually 17, 29, 34 mm, etc. The metal straight tube 15 can be made of alloy steel.

[0025] As an optional embodiment, the bracket includes a lower bracket 17 and an upper bracket 10. The lower end of the metal straight tube 15 is connected to the inner wall of the tubular shell 6 through the lower bracket 17.

The positive electrode of the high-voltage pulse power supply 12 is electrically connected to the terminal block 14, and the negative electrode of the high-voltage pulse power supply 12 is electrically connected to the metal straight tube 15. The cylindrical insulated electrode rods 5 serve as high-voltage electrodes, and the metal straight tube 15 serves as ground electrodes. A non-uniform high-voltage pulse electric field is formed between the cylindrical insulated electrode rods 5 and the metal straight tube 15. The terminal block 14 can be connected to all cylindrical insulated electrode rods 5 through the terminal studs 13, saving wires. The high-voltage pulse power supply 12 only needs to be connected to the terminal block 14 to achieve communication with all cylindrical insulated electrode rods 5, without using multiple wires to connect multiple cylindrical insulated electrode rods 5, thus saving wire usage.

[0027] The upper outer wall of the tubular housing 6 is provided with a wiring conduit 11 for facilitating the passage of wires. The high-voltage pulse power supply 12 can utilize either a high-frequency, high-voltage pulsed AC power supply or a high-frequency, high-voltage pulsed DC power supply, with a voltage of 0-20 kV, a frequency of 50-5000 Hz, a duty cycle of 0-30%, and a square wave waveform. The optimal frequency, voltage, and duty cycle are determined based on specific sludge physical and chemical properties.

[0028] As an optional embodiment, an insulating layer is provided on the outer surface of the cylindrical insulated electrode rod 5, and the thickness of the insulating layer is 1 to 2 mm. The insulating layer of the cylindrical insulated electrode rod 5 can be formed by spraying ceramic powder on its surface, heat-coating a soft plastic tube, etc., or a hot-dip plastic steel tube can be used.

[0029] As an optional embodiment, the material used for the flow-disrupting element 16 can be polytetrafluoroethylene insulating material. The number of the flow-disrupting elements 16 is the same as the number of the cylindrical insulated electrode rods 5. The flow-disrupting element 16 includes a sleeve 18 and a flow-disrupting portion. The flow-disrupting portion is fixedly connected to the side wall of the sleeve 18. The sleeve 18 is sleeved on the cylindrical insulated electrode rod 5 and is used to position and fix the cylindrical insulated electrode rod 5. The flow-disturbing part is a branch-like structure 19 or a continuous spiral blade structure 20 or an intermittent spiral blade structure 21. Its function is to interfere with the flow of sludge when it passes through the flow channel space, causing strong turbulence, which helps to break the wall and dehydrate the sludge. Figure 6 , is a branch-like structure 19, with multiple branch rods on the sleeve 18, and the free ends of the branch rods face upwards, in the same direction as the sludge flow; see Figure 7 , there are multiple branch rods on the sleeve 18, the free ends of the branch rods face downward, opposite to the sludge flow direction; see Figure 8 , is a discontinuous spiral blade structure 21, whose blades are discontinuous and spirally distributed along the sleeve 18; see Figure 9 , which is a continuous spiral blade structure 20, whose blades are continuous and spirally distributed along the sleeve 18.

The six positioning tubes 22 are respectively fixedly connected by the positioning tube 22 at the center of the corresponding flow stabilizing blade 9. Two adjacent ones of the six positioning tubes 22 are fixedly connected by the flow stabilizing blade 9. The six positioning tubes 22 are then fixedly connected to the inner wall of the tubular shell 6 through the corresponding flow stabilizing blade 9. After the sludge is broken by the high-voltage pulse electric field wall-breaking structure 4, it is stabilized and vortex-broken under the action of the flow-stabilizing blades 9, and finally flows out through the sludge outlet pipe 2 for subsequent sludge treatment process.

[0031] As an optional embodiment, a sludge inlet pipe 8 and an inlet expansion section 7 are provided at the bottom of the tubular shell 6. The sludge inlet pipe 8 is located below the inlet expansion section 7. The diameter of the inlet expansion section 7 gradually increases from bottom to top. A sludge outlet pipe 2 is provided on the upper side wall of the tubular shell 6. The height of the sludge outlet pipe 2 is higher than the height of the flow stabilizing structure 3.

[0032] The present invention operates as follows: Sludge enters the high-voltage pulse electric field wall-breaking structure 4 from the bottom up through the sludge inlet pipe 8 at the bottom of the tubular housing 6. The electrical energy generated by the high-voltage pulse power supply 12 creates a non-uniform high-voltage pulse electric field between the cylindrical insulated electrode rod 5 and the metal straight tube 15. As the sludge passes through the non-uniform high-voltage pulse electric field, its cell walls are destroyed, organic matter is dissolved, and the strong turbulence of the flow-disrupting element 16 achieves cell wall breaking and dehydration. Subsequently, as the sludge passes through the flow-stabilizing structure 3, the flow-stabilizing blades 9 stabilize the flow and break up vortices. Finally, the wall-broken sludge flows out through the sludge outlet pipe 2.
