Description

Technical Field

[0001] The utility model relates to the technical field of water distributors, in particular to a UASB anaerobic tank water distributor which is easy to maintain. Background Art

[0002] The existing bottom water distribution pipeline is an octagonal water distribution bucket at the bottom. In order to achieve the purpose of uniform water distribution, the octagonal water distribution bucket is distributed at the bottom of the tank with a water outlet of 50mm. When the sludge in the sludge bed at the bottom of the UASB anaerobic tank is silted, the water distribution bucket and the water distribution pipeline are blocked, affecting the anaerobic effect. The only way to solve the blockage is to empty the tank body to dredge and replace the pipeline. To solve the blockage problem, the maintenance time is long, the cost is high, and the engineering workload is large. Therefore, we propose a UASB anaerobic tank water distributor that is easy to maintain. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 The utility model provides a technical solution: a UASB anaerobic tank water distributor that is easy to maintain, including a UASB anaerobic tank body 1, a mounting frame 4 is installed on the top of the UASB anaerobic tank body 1, and a water distributor body 3 is installed in the mounting frame 4. The water distributor body 3 is installed on the top of the UASB anaerobic tank body 1 through the mounting frame 4, which solves the problem that the traditional water distributor body 3 is installed at the bottom of the UASB anaerobic tank body 1, resulting in the result that the UASB anaerobic tank body 1 can only be emptied to clear the pipeline and replace it when it is blocked, resulting in a long maintenance time, high cost and large engineering workload.

[0022] The water distributor body 3 is fixedly installed on the top of the UASB anaerobic tank body 1 through the mounting frame 4. The water distributor body 3 includes an inner ring tube 5 and an outer ring tube 9. The inner ring tube 5 is a quadrilateral structure as a whole, and the outer ring tube 9 is a hexagonal structure as a whole. Water distribution inlet branch pipes 6 are installed on the four sides of the inner ring tube 5, and the ends of the water distribution inlet branch pipes 6 extend into the bottom end of the inside of the UASB anaerobic tank body 1. Circulating water outlet branch pipes 10 are installed on the six sides of the outer ring tube 9, and the ends of the circulating water outlet branch pipes 10 extend into the bottom end of the inside of the UASB anaerobic tank body 1.

[0023] It should be noted that the utility model has a hole in the top of the UASB anaerobic tank body 1, and the inner ring pipe 5 adopts DN50 and PE pipes to set four water distribution inlet branches 6. The liquid flow rate in the inner ring pipe 5 is accelerated by the quadrilateral structure. The water inlet of the quadrilateral water distribution structure is directly connected to the water inlet pump pipe without intermediate diversion, thereby achieving the purpose of delaying the clogging of the water distribution inlet branch 6. The hexagonal structure of the outer ring pipe 9 uses DN65 and PE pipes. The hexagonal water distribution pipe is directly connected to the outlet of the circulation pump to carry out the UASB anaerobic tank body 1 itself. Circulation can achieve the purpose of uniform water distribution, increasing flow rate and preventing clogging. For leachate water distribution and circulating water distribution, a fixed sleeve 2 is set inside the UASB anaerobic tank 1. When the liquid level of the UASB anaerobic tank 1 exceeds the bottom of the fixed sleeve 2, the biogas overflow can be isolated to ensure the safety of internal pipe maintenance and replacement. When the water distributor body 3 needs to be maintained or replaced, the lifting ring 12 on the top is suspended by a crane, and the clogged water distribution pipe can be lifted directly from the top for maintenance or replacement, without stopping production to empty the UASB anaerobic tank 1.

[0024] The mounting frame 4 includes a mounting rod 13 and a fixing frame 17 . The four side walls of the fixing frame 17 are symmetrically fixedly connected with the mounting rod 13 . The inner ring tube 5 and the outer ring tube 9 are fixedly connected inside the mounting rod 13 .

[0025] It should be noted that each side of the quadrilateral inner ring tube 5 is fixed to the outer ring tube 9 by two mounting rods 13, and multiple mounting rods 13 are fixed by a fixing frame 17 to form an integral mounting frame 4, so that it can fix the water distributor body 3 more stably.

[0026] A magnet 15 is installed at the bottom of the mounting rod 13 , an annular mounting plate 14 is fixedly connected to the top of the UASB anaerobic tank body 1 , and an electromagnet 16 is installed at the top of the annular mounting plate 14 just below the magnet 15 .

[0027] It should be noted that, by placing a magnet 15 at the bottom of the mounting rod 13, after the water distributor body 3 is installed on the top of the UASB anaerobic tank body 1, the control system provided in the device controls the electromagnet 16 to be energized, so that the bottom of the mounting rod 13 is firmly connected to the top of the annular mounting plate 14, thereby ensuring the stability of the installation of the water distributor body 3.

[0028] The magnetism of the electromagnet 16 when energized is opposite to that of the magnet 15 .

[0029] It should be noted that the electromagnet 16 can quickly attract the magnet 15 when energized, thereby ensuring the stability of the overall connection.

[0030] A first stainless steel ball valve 8 is installed at one end of the water distribution inlet branch pipe 6 located at the inner ring pipe 5 , and a second stainless steel ball valve 11 is installed at one end of the circulating water outlet branch pipe 10 located at the outer ring pipe 9 .

[0031] It should be noted that the first stainless steel ball valve 8 can control the on-off of the liquid inside the water distribution inlet branch pipe 6 , and the second stainless steel ball valve 11 can control the on-off of the liquid inside the circulating water outlet branch pipe 10 .

[0032] The positions of the water distribution inlet branch pipe 6 and the circulating water outlet branch pipe 10 in the UASB anaerobic tank body 1 are fixedly connected with fixed sleeves 2 , and the water distribution inlet branch pipe 6 and the circulating water outlet branch pipe 10 are both located in the fixed sleeves 2 .

[0033] It should be noted that for leachate distribution and circulating water distribution, a fixed sleeve 2 is provided inside the UASB anaerobic tank 1. When the liquid level of the UASB anaerobic tank 1 exceeds the bottom of the fixed sleeve 2, the biogas can be isolated from overflowing, ensuring the safe maintenance and replacement of the inner pipe.

[0034] A lifting ring 12 is symmetrically fixedly connected to the top of the mounting frame 4 .

[0035] It should be noted that when the water distributor body 3 needs to be maintained or replaced, the lifting ring 12 on the top is suspended by a crane, and the clogged water distribution pipe can be directly lifted from the top for maintenance or replacement, without stopping production to empty the UASB anaerobic tank 1.

[0036] A connecting pipe 7 is connected to the outer side of the inner ring pipe 5 , and an end of the connecting pipe 7 is connected to the outer ring pipe 9 .

[0037] It should be noted that the arrangement of the connecting pipe 7 can realize circulating water distribution.
