Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, specifically to a horizontally moving mesh box-type anaerobic generator. Background Technology

[0002] Traditional processing methods include anaerobic fermentation systems such as CSTR, USR, and plug flow systems, all of which have their own drawbacks.

[0003] Traditional CSTR anaerobic fermentation can experience fluctuations in gas production, sometimes affecting or halting it, due to temperature changes within the fermentation vessel. Furthermore, when feed is introduced and the mixture is stirred, gas production increases dramatically, causing a rapid accumulation of biogas within the vessel. This can generate immense pressure, posing a serious safety hazard, potentially leading to vessel rupture.

[0004] Traditional USRs rely solely on a circulating water pump to circulate water and generate an anaerobic reaction. However, the wastewater contains a large amount of impurities and mud, which can easily accumulate at the bottom of the reaction tank, leading to incomplete reactions.

[0005] Traditional plug-flow anaerobic fermentation systems, when dealing with waste such as kitchen waste, simply separate bones and meat from the waste as solids using a solid-liquid separator. This process is complex and incomplete, resulting in high operating costs. Summary of the Invention

[0006] The purpose of this invention is to provide a transversely moving mesh cage anaerobic generator, which solves the shortcomings of traditional treatment methods such as low safety, incomplete reaction due to bottom accumulation, complex operation, and high operating costs.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0030] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] Please see Figure 1 The transversely moving net cage anaerobic generator shown in one embodiment of this application includes a pool body 1, a net cage 2, an oil outlet pipe 3, an overflow pipe 4, a circulation system 5, a gas collection system 6, a liquid discharge system 7, and a sludge discharge system 8.

[0032] The pool body 1 is rectangular in shape and is divided into seven compartments. The first compartment on the left is the unloading pool 10, the second and third compartments are the primary oil separators 11, the fourth and fifth compartments are the secondary oil separators 12, the sixth compartment is the hydrolysis acidification pool 13, and the seventh compartment is the anaerobic pool 14.

[0033] The leftmost unloading pool 10 of the pool body 1 is equipped with several net cages 2. The front outer wall of the pool body 1 is equipped with several oil outlet pipes 3. The oil outlet pipes 3 are connected to the unloading pool 10, the primary oil separator 11, and the secondary oil separator 12 respectively. Several overflow pipes 4 are connected between the secondary oil separator 12 and the hydrolysis acidification pool 13. The circulation system 5 is located on the rear and right sides of the pool body 1 and is connected to the hydrolysis acidification pool 13 and the anaerobic pool 14 respectively. The gas collection system 6 is located on the upper part of the pool body 1 and is connected to the middle of the anaerobic pool 14. The liquid discharge system 7 is located on the right front side of the pool body 1 and is connected to the anaerobic pool 14. The sludge discharge system 8 is located on the lower part of the pool body 1 and is connected to the unloading pool 10, the primary oil separator 11, the secondary oil separator 12, the hydrolysis acidification pool 13, and the anaerobic pool 14 respectively.

[0034] The unloading pool 10 has several discharge lifting devices 100 on the rear wall edge, several feeding lifting devices 101 on the front wall edge corresponding to the discharge lifting devices 100, a hook and rope 102 on the left wall edge, several discharge pulleys 103 on the rear inner wall of the unloading pool 10, a feeding track 104 on the front inner wall of the unloading pool 10, and a wire mesh cage traveling track 105 between the front and rear inner walls inside the unloading pool 10.

[0035] The cage walking track 105 is fixed at a higher position on the side near the feeding track 104, and at a lower position on the side near the discharge pulley 103, presenting a certain slope.

[0036] The net cage 2 includes a hook lock 20, net cage traveling pulleys 21, net cage body 22, and net cage loading and unloading pulleys 23. The net cage body 22 is provided with a hook lock 20 on the top, and several net cage traveling pulleys 21 are provided on the left and right sides of the middle of the net cage body 22. The net cage body 22 is provided with net cage loading and unloading pulleys 23 at the four corners in front of the net cage body 22.

[0037] The circulation system 5 branches out into several equally spaced branch pipes at the location connecting the hydrolysis acidification tank 13 and the anaerobic tank 14.

[0038] 10. Unloading pool, 11. Primary oil separator, 12. Secondary oil separator, 13. Hydrolysis acidification pool, 14. Anaerobic pool with a trapezoidal bottom sludge discharge ditch, 15.

[0039] In use, after the net cage (2) is filled with material outside the pool, the material is hoisted from outside the pool to inside the pool by the feeding hoist (101). Because the liquid below the surface is turbid, the net cage travel track (105) is not visible. Only by aligning the feeding track (104) with the net cage travel pulley (21) on the net cage (2) can the net cage (2) be accurately placed on the net cage travel track (105). After the net cage is placed, the hook lock (20) is hung on Figure 6 The net cage (2) is dragged on the hook rope (102). Multiple net cages (2) are placed on the entire net cage walking track (105). Any one of the net cages (2) is hooked into the pool by the feeding hoist (101) and is hooked out of the pool by the discharging hoist (100), realizing a cycle of oil overflow and organic matter hydrolysis and acidification.

[0040] Because grease is less dense than water, it will float to the surface after overflowing. The outlet of the oil pipe (3) on the unloading pool (10), the primary oil separator (11), and the secondary oil separator (12) is above the liquid surface. The oil pipe (3) collects the grease in the unloading pool (10), the primary oil separator (11), and the secondary oil separator (12) and discharges it outside the pool body for the next process.

[0041] The partition walls on the unloading pool (10), the primary oil separator (11), and the secondary oil separator (12) function the same as those on traditional oil separators, thus better promoting oil-water separation.

[0042] After the raw water in the secondary oil separator (12) is separated from the oil, it overflows into the hydrolysis acidification tank through the overflow pipe (4).

[0043] The hydrolysis acidification tank (13) further hydrolyzes the organic matter in the raw water and flows into the anaerobic tank (14).

[0044] According to process requirements, the hydrolysis acidification tank (13) can be expanded into a hydrolysis acidification tank with a fixed box-type anaerobic reactor and a vertically moving net box-type anaerobic generator.

[0045] The function of the circulation system (5) is to draw water from the anaerobic tank (14) to the hydrolysis acidification tank (13) to achieve process reflux and also to achieve the function of stirring.

[0046] The biogas produced by anaerobic fermentation is collected by the gas collection system (6) and transported to the next process.

[0047] Throughout the process, the sludge produced by the liquid will be collected in the sludge discharge ditch (15) at the bottom of the tank (1), and then pumped out of the tank by the sludge discharge system (8) for the next process.

[0048] Liquid discharge system (7) such as Figure 1 , 2The waste liquid produced after anaerobic fermentation in the anaerobic tank (14) is discharged to the next process.

[0049] This process can also be used as a hydrolysis acidification tank at the front end of CSTR, USR, and UASB.

[0050] In summary, this utility model discloses a transversely moving mesh box-type anaerobic generator, which makes loading and unloading materials more convenient than traditional grease traps. Its track entry and derailment devices simplify the operation steps, reduce the number of operators, and can perform oil-water separation and anaerobic fermentation, truly achieving the reduction of kitchen waste, lowering the investment cost of kitchen waste treatment, reducing operating costs, and ensuring safety. Compared with traditional anaerobic fermentation systems such as CSTR, USR, and plug flow systems, it has a significant cost advantage.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
