Description

Technical Field

[0001] The utility model relates to an IC internal circulation anaerobic reactor, in particular to an IC internal circulation anaerobic reactor sewage discharge structure, belonging to the technical field of internal circulation anaerobic reactors. Background Art

[0002] The IC anaerobic reactor is a new type of anaerobic reactor after UASB and EGSB. It has the characteristics of high volumetric load, strong impact load resistance, good effluent stability, large gas production, low sludge volume, low operating cost and obvious economic benefits. It is particularly suitable for medium and high concentration sewage treatment projects. The IC internal circulation anaerobic reactor is equipped with a water distributor at the bottom of its main body, a sludge layer is arranged above the water distributor, and two sets of three-phase separators are arranged above the sludge layer. At the same time, a cyclone gas-liquid separator is installed on the upper part of the main body, and a circulation pipeline is arranged in the reactor body. When in use, the sewage is pumped into the water distributor and evenly dispersed into the reactor body. The sewage is anaerobically decomposed by the microorganisms in the sludge, and solid-liquid-gas separation is carried out through two sets of three-phase filters. At the same time, the sewage inside the reactor will be filtered multiple times in the main body through the circulation pipeline. Finally, the sewage will pass through the cyclone gas-liquid separator to separate the water and the generated biogas and discharge them.

[0003] However, it was found during use that the commonly used internal circulation anaerobic reactor is only equipped with two sludge outlets. When there is too much anaerobic sludge, it will cause accumulation in the reactor. Relying only on the two sludge outlets, it is impossible to discharge and clear the sludge accumulation location, thereby reducing the operating efficiency of the internal circulation anaerobic reactor.

[0004] Therefore, there is an urgent need to improve the sewage discharge structure of an IC internal circulation anaerobic reactor to solve the above-mentioned problems. Utility Model Content

At the same time, a plurality of backwashers are arranged between every two adjacent sewage discharge pipes. The accumulated sludge can be flushed by the backwashers, which is more helpful for sludge discharge and dredging, so as to improve the operation efficiency of the reactor main body.

[0006] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include:

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 4 As shown, this embodiment provides an IC internal circulation anaerobic reactor sewage discharge structure embodiment.

[0024] A sewage discharge structure of an IC internal circulation anaerobic reactor comprises a reactor body 1 and a water inlet 2. A sewage discharge structure body 3 is arranged on the reactor body 1. The sewage discharge structure body 3 comprises a tee pipe 4 fixedly mounted at the bottom of the reactor body 1. A sludge ring pipe 5 is fixedly mounted on the tee pipe 4. A plurality of sewage discharge pipes 6 are evenly arranged on the top of the sludge ring pipe 5. A plurality of backwashers 7 are fixedly mounted between two adjacent sewage discharge pipes 6. Through the arrangement of the sewage discharge structure body 3, a sludge ring pipe 5 with a larger inner diameter is added at the bottom of the reactor body 1, and a plurality of sewage discharge pipes 6 are arranged at the bottom of the sludge ring pipe 5. The sludge is discharged into the sludge ring pipe 5 through the tee pipe 4, and then discharged outward through the plurality of sewage discharge pipes 6, so as to discharge and dredge the accumulated sludge. At the same time, a plurality of backwashers 7 are arranged between every two adjacent sewage discharge pipes 6. The accumulated sludge can be washed by the backwashers 7, which is more helpful for sludge discharge and dredge, so as to improve the operation efficiency of the reactor body 1.

[0025] A plurality of flanges 8 are fixedly installed at the connection points between the sludge ring pipe 5 and the sewage pipe 6 as well as the sewage pipe 6 and the backwasher 7. The plurality of flanges 8 are fixedly connected by a plurality of bolts. A fixing frame 9 is fixedly installed at one end of the water inlet 2. A bidirectional screw 10 is movably installed on the fixing frame 9. A turntable 11 is fixedly installed at one end of the bidirectional screw 10. Two moving blocks 12 connected by threads are symmetrically arranged on the bidirectional screw 10. A fixing rod 13 is fixedly installed on the moving block 12. A fixing ring 14 is fixedly installed on the fixing rod 13. A sealing ring is fixedly installed on the inner wall of the fixing ring 14. By setting the flange 8 and the bolts, multiple backwashers 7 and backwashers 7 can be disassembled, which is convenient for replacement when they are damaged. By setting the fixing frame 9, the bidirectional screw 10, the turntable 11, the moving block 12, the fixing rod 13 and the fixing ring 14, when the external water inlet pipe is connected to the water inlet 2, the bidirectional screw 10 is rotated to make the two moving blocks 12 move relatively at the same time, so that the two fixing rings 14 clamp the connected water inlet pipe, so that the external water inlet pipe can be firmly connected to the water inlet 2 to prevent loosening and falling off. By setting the sealing ring, the connection can be sealed to prevent water leakage.

[0026] A plurality of push rods 15 are evenly fixedly installed on the surface of the turntable 11, and anti-slip grooves are arranged on the surface of the push rods 15. A limit frame 16 is fixedly installed on the top of the fixed frame 9, and a limit block 17 is fixedly installed on the top of the fixed rod 13. The limit frame 16 and the limit block 17 are arranged to be slidably connected. Through the arrangement of the push rods 15, after a plurality of push rods 15 are evenly arranged on the surface of the turntable 11, it is more convenient to rotate the turntable 11 to drive the bidirectional screw 10 to rotate. Through the arrangement of the limit frame 16 and the limit block 17, since the limit frame 16 and the limit block 17 are slidably connected, the limit block 17 can slide on the limit frame 16 when the moving block 12 moves, and can also limit the moving block 12 while sliding, so that it can drive the fixed ring 14 to move smoothly and avoid skewing.

[0027] In this embodiment, if Figure 1-Figure 4 As shown, the working process of the IC internal circulation anaerobic reactor sewage discharge structure provided in this embodiment is as follows:

[0028] A sludge ring pipe 5 with a larger inner diameter is added at the bottom of the reactor body 1, and a plurality of sewage pipes 6 are arranged at the bottom of the sludge ring pipe 5. The sludge is discharged into the sludge ring pipe 5 through the tee pipe 4, and then discharged outward through the plurality of sewage pipes 6, so as to discharge and dredge the accumulated sludge. At the same time, a plurality of backwashers 7 are arranged between every two adjacent sewage pipes 6, and the accumulated sludge can be flushed by the backwashers 7, which is more helpful for sludge discharge and dredging.

[0029] In summary, in this embodiment, according to the sewage discharge structure of an IC internal circulation anaerobic reactor of this embodiment, through the arrangement of the flange 8 and the bolts, the multiple backwashers 7 and the backwashers 7 can be disassembled, which is convenient for replacement when they are damaged. Through the arrangement of the fixing frame 9, the bidirectional screw 10, the rotating disk 11, the moving block 12, the fixing rod 13 and the fixing ring 14, when the external water inlet pipe is connected to the water inlet 2, the bidirectional screw 10 is rotated to make the two moving blocks 12 move relatively at the same time, so that the two fixing rings 14 clamp the connected water inlet pipe, so that the external water inlet pipe and the water inlet 2 can be stably connected. The connection is firm to prevent loosening and falling off. The sealing ring can be set to seal the connection to prevent water leakage. After the push rod 15 is evenly set on the surface of the turntable 11, it is more convenient to rotate the turntable 11 to drive the bidirectional screw 10 to rotate. The limit frame 16 and the limit block 17 are set. Because the limit frame 16 and the limit block 17 are slidably connected, the limit block 17 can slide on the limit frame 16 when the moving block 12 moves. While sliding, it can also limit the moving block 12, so that it can steadily drive the fixed ring 14 to move and avoid skewing.

[0030] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0031] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.
