Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 This utility model provides a technical solution:

[0026] A waste co-processing system with biogas power generation components includes an anaerobic fermentation system 1. A dehydration system 2 is connected to one side of the anaerobic fermentation system 1 via pipes and a blower. A desulfurization system 3 is connected to one side of the dehydration system 2 via pipes and a blower. A biogas power generation device 5 is installed on one side of the desulfurization system 3. A gas filtration mechanism 4 is installed between the desulfurization system 3 and the biogas power generation device 5 to filter the biogas. The gas filtration mechanism 4 includes:

[0027] The filter unit 41 is located on the right side of the desulfurization system 3. It includes a filter barrel 411, which is filled with water. An air inlet pipe 414 is fixedly installed on the left side of the filter barrel 411. One end of the filter barrel 411 is inserted into the water inside the handle 4111, and the other end of the air inlet pipe 414 is connected to the desulfurization system 3. A placement bucket 419 is fixedly installed inside the filter barrel 411, and activated carbon is placed inside the placement bucket 419 to filter the particles inside the biogas and remove odors.

[0028] The cleaning unit 42 is located in front of the filter unit 41 and is used to filter the water inside the filter canister 411.

[0029] The biogas is dehydrated by the dehydration system 2, which prevents incomplete combustion and reduced energy release efficiency caused by excessive water content in the biogas.

[0030] By using the desulfurization system 3, the biogas is desulfurized, which can effectively remove hydrogen sulfide, prevent equipment corrosion, and extend the service life of the equipment.

[0031] The anaerobic fermentation system 1, dehydration system 2, desulfurization system 3, gas filtration mechanism 4, and biogas power generation device 5 are all connected by pipelines, and the pipelines are equipped with fans for transporting biogas.

[0032] In this embodiment, a fixing ring plate 415 is fixedly installed inside the filter barrel 411. A rubber sleeve 416 is fitted inside the inner ring of the fixing ring plate 415. A placement barrel 419 is inserted and installed inside the rubber sleeve 416. Four fixing seats 417 are installed in a circular array on the top of the fixing ring plate 415. A slot 418 is opened inside the fixing seat 417. Four locking blocks 4110 are installed in a circular array on the outer side of the placement barrel 419. The locking blocks 4110 slide into the slot 418 to realize the assembly and disassembly of the placement barrel 419.

[0033] The placement bucket 419 is inserted into the vertical groove of the slot 418 by the locking block 4110, and the placement bucket 419 is rotated so that the locking block 4110 is inserted into the horizontal groove of the slot 418, thereby making it easy to disassemble and assemble the placement bucket 419 and to replace the activated carbon inside the placement bucket 419.

[0034] In this embodiment, a set of handles 4111 are symmetrically fixed inside the placement bucket 419 for taking the placement bucket 419. The bottom of the placement bucket 419 is provided with an air hole 4112 for biogas to enter the interior of the placement bucket 419 and come into contact with the activated carbon inside the placement bucket 419 to remove odors.

[0035] The biogas produced inside the anaerobic fermentation system 1 is dehydrated by the dehydration system 2 and desulfurized by the desulfurization system 3. After dehydration, it enters the water in the filter bucket 411 through the air inlet pipe 414. The water filters the particles inside the biogas. The filtered biogas enters the placement bucket 419 through the air hole 4112 and comes into contact with the activated carbon inside the placement bucket 419 to remove odors. This achieves the filtration and odor removal of biogas, thereby preventing unfiltered biogas from entering the biogas power generation device 5 and causing damage to the biogas power generation device 5.

[0036] In this embodiment, a top cover 412 is fixedly installed on the top of the filter bucket 411 by bolts, and an exhaust pipe 413 is fixedly installed on the top of the top cover 412, with one end of the exhaust pipe 413 connected to the biogas power generation device 5.

[0037] The top cover 412 is fixedly installed on the top of the filter bucket 411 by bolts, which facilitates the placement of the bucket 419.

[0038] In this embodiment, the cleaning unit 42 includes a water inlet pipe 425 fixedly installed at the bottom of the filter bucket 411, and a first water pump 424 is fixedly installed at one end of the water inlet pipe 425. The output end of the first water pump 424 is connected to and installed with a filter box 421. Three sets of fixing frames 422 are fixedly installed inside the filter box 421. Filter plates 423 are slidably inserted into the fixing frames 422 for filtering the water inside the filter bucket 411.

[0039] The first water pump 424, model 42113-25A, is electrically connected to an external power source and is operated by a human control panel. The first water pump 424 transports water from the inside of the filter bucket 411 to the inside of the filter box 421 through the inlet pipe 425. The water passes through the three filter plates 423 to filter the particles in the water. Then, the second water pump 427 runs and flows back into the inside of the filter bucket 411 through the drain pipe 426, thus realizing the repeated use of the water inside the filter bucket 411.

[0040] In this embodiment, a drain pipe 426 is fixedly installed on the top of the filter box 421, and one end of the drain pipe 426 passes through the filter box 421 and extends into the interior of the filter box 421. A second water pump 427 is fixedly installed on the other end of the drain pipe 426, and the output end of the second water pump 427 is fixedly connected to the filter barrel 411 through a pipe.

[0041] The model of the drain pipe 426 is 42113-25A. It is electrically connected to an external power source and can be opened and closed by a human-operated control panel. The operation of the drain pipe 426 allows the water filtered inside the filter box 421 to flow back into the filter bucket 411, so that the water inside the filter bucket 411 can be reused.

[0042] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0043] During operation, the biogas produced inside the anaerobic fermentation system 1 is first dehydrated by the dehydration system 2 and desulfurized by the desulfurization system 3. Then, it enters the water in the filter bucket 411 through the air inlet pipe 414. The water filters the particles inside the biogas. The filtered biogas enters the placement bucket 419 through the air hole 4112 and comes into contact with the activated carbon inside the placement bucket 419 to remove odors. After filtering and removing odors from the biogas, the filtered biogas enters the biogas power generation device 5 through the exhaust pipe 413. The biogas power generation device 5 then burns the biogas to generate electricity.

[0044] Then, the first water pump 424 operates to transport water from inside the filter bucket 411 to inside the filter box 421 through the inlet pipe 425. The water passes through the three filter plates 423 to filter the particles in the water. After that, the second water pump 427 operates to return the water to inside the filter bucket 411 through the drain pipe 426.
