DETAILED DESCRIPTION
[0023] 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.
[0024] See also Figure 1-4The utility model provides a technical solution: an anaerobic reactor water distribution structure that uses water flow impact to complete mixing, including a mixing tank 1, a water distribution component 200 for making a water distribution space is installed on the inner side of the mixing tank 1, and an auxiliary component 300 for assisting wastewater treatment is installed on the outer side of the mixing tank 1; through the coordinated use of the water distribution component 200 inside the mixing tank 1 and the auxiliary component 300 outside the mixing tank 1, the impact force of the water flow entering can be used to fully mix and stir the high-concentration sludge at the bottom, thereby accelerating the process of the circulation reaction and improving the effect of the anaerobic reaction. By partitioning the internal space and using the impact force of the water flow entering, the incoming water flow can push the wastewater-sludge mixture at the bottom to stir and form a vortex, thereby strengthening the mass transfer effect of the anaerobic reaction. At the same time, through the high-intensity hydraulic shearing capacity, it is conducive to the formation of anaerobic granular sludge, improving the effect of the anaerobic reaction, and effectively improving the practicality of the water distribution device.
[0025] In this embodiment, the water distribution assembly 200 is a structure used to enhance the mass transfer effect and improve the overall efficiency.
[0026] like Figure 1 , Figure 2 and Figure 4 As shown, the water distribution assembly 200 includes a hollow cone 201 fixed to the inner side of the mixing tank 1, a plurality of partition plates 202 fixed to the inner side of the mixing tank 1 and evenly distributed on the outer side of the hollow cone 201, a conical block 203 fixed to the inner side of the mixing tank 1 and located inside the hollow cone 201, and a mixing water inlet 204 that penetrates and is fixed to the outer side of the mixing tank 1 and is evenly distributed.
[0027] It should be noted that the mixing water inlet 204 includes a water inlet pipe 241 that passes through and is fixed on the outside of the mixing tank 1, a mixing tube 242 that is fixed on the outside of the hollow cone 201, and a bent tube 243 that is fixed on the side of the mixing tube 242 close to the hollow cone 201. The end of the water inlet pipe 241 away from the mixing tank 1 extends to the interior of the corresponding mixing tube 242, and the end of the mixing tube 242 away from the hollow cone 201 is open. The inner diameter of the end of the mixing tube 242 away from the hollow cone 201 is larger than the inner diameter of the end close to the hollow cone 201, so that the wastewater output from the inside of the water inlet pipe 241 can enter the interior of the mixing tube 242, and can drive the sludge inside the mixing reaction zone to move through the negative pressure of the water flow under the action of the opening, thereby completing the pre-mixing inside the mixing tube 242.
[0028] At the same time, the bending tube 243 is bent at a forty-five degree angle in the counterclockwise direction. The bending tube 243 is located inside the hollow cone 201, so that the wastewater discharged through the bending tube 243 can be transported according to the bending angle, thereby driving the sludge and wastewater around the conical block 203 to be stirred and mixed.
[0029] In addition, the front side of the hollow cone 201 is open, and the mixing water inlet 204 is evenly distributed on the outside of the conical block 203 at one end thereof close to the conical block 203. The side of the partition plate 202 close to the hollow cone 201 is fixedly connected to the outside of the hollow cone 201. A mixing reaction zone is formed between two adjacent partition plates 202. The number of mixing reaction zones is not less than six. The number of mixing water inlets 204 is equal to the number of mixing reaction zones, and the mixing water inlets 204 are located inside the corresponding mixing reaction zones, so that the wastewater can enter the inside of the hollow cone 201 through the mixing water inlet 204, and can be rotated and mixed around the conical block 203, so that the water flow can form a vortex to accelerate the reaction.
[0030] In this embodiment, the auxiliary component 300 is a structure for assisting in wastewater treatment and discharge.
[0031] like Figure 1 and Figure 3 As shown, the auxiliary component 300 includes a plurality of discharge pipes 301 fixed to the outside of the mixing tank 1, an electric valve 302 fixedly installed on the outside of the discharge pipe 301, three drain pipes 303 fixed to the outside of the mixing tank 1, two supporting strips 304 fixed to the inside of the mixing tank 1, a mud guard mesh plate 305 slidably connected between the outer sides of the two supporting strips 304, and a fixed plate 306 fixed to the right side of the mud guard mesh plate 305.
[0032] It should be noted that the discharge pipe 301 is divided into an outer circle group and an inner circle group. The number of the discharge pipes 301 in the inner circle group is five, and they are distributed between the outer side of the conical block 203 and the inner side of the hollow cone 201. The number of the outer circle group is equal to the number of the mixing reaction zones, and they are located on the back side of the corresponding mixing reaction zones, so that the discharge pipe 301 can conveniently discharge the wastewater and sludge in the mixing reaction zones and the hollow cone 201 in a unified manner.
[0033] In addition, the two supporting strips 304 are symmetrically distributed, and an insertion hole for the mud guard mesh 305 to enter is opened on the outer side of the mixing tank 1. The left side of the mud guard mesh 305 is inclined toward the side close to the hollow cone 201, and the mud guard mesh 305 is located on the front side of the hollow cone 201. The drain pipe 303 is located on the front side of the mud guard mesh 305 and on the left side of the mixing tank 1. The left side of the fixed plate 306 is in contact with the outer side of the mixing tank 1, and a handle is fixedly installed on the right side of the fixed plate 306, so that the wastewater inside the mixing tank 1 can filter the internal sludge under the appropriate filtering and blocking effect of the mud guard mesh 305, and the filtered wastewater can be discharged through the drain pipe 303. Since the mud guard mesh 305 is inclined to the left, it is not easy for the wastewater to overflow through the connection between the fixed plate 306 and the mixing tank 1 when discharged.
[0034] It should also be noted that the structural descriptions in this paper are based on Figure 1 From the main perspective, the mud guard mesh plate 305 only functions to properly block the sludge, and does not need to effectively filter the sludge.
[0035] The working principle of the above embodiment is:
[0036] During treatment, part of the sludge, wastewater and catalyst are poured into the mixing tank 1, and the wastewater is continuously input into the hollow cone 201 through the mixing water inlet 204. During the input process, due to the impact force of the water flow, a negative pressure state is formed at the opening of the mixing tube 242, so that the surrounding sludge can be sucked in and moved to the inside of the mixing tube 242 to mix with the wastewater, and then discharged together through the bending tube 243, so that the inside of the hollow cone 201 forms a vortex under the restriction of the conical block 203, thereby strengthening the mass transfer effect of the anaerobic reaction. The sewage after the reaction is completed flows out through the top of the hollow cone 201, and the sludge falls into the space around the partition plate 202 to mix and react with the wastewater that enters later. The sewage on the top is filtered out of the internal sludge under the action of the mud guard mesh plate 305, and is discharged through the drain pipe 303 to complete the wastewater treatment.
[0037] Compared with the prior art, the anaerobic reactor water distribution structure that uses water flow impact to complete mixing, through the coordinated use of the water distribution component 200 inside the mixing tank 1 and the auxiliary component 300 outside, can use the impact force of the water flow entering to fully mix and stir the high-concentration sludge at the bottom, thereby accelerating the circulation reaction process and improving the effect of the anaerobic reaction. By partitioning the internal space and using the impact force of the water flow entering, the incoming water flow can drive the wastewater-sludge mixture at the bottom to stir and form a vortex, thereby enhancing the mass transfer effect of the anaerobic reaction. At the same time, through the high-intensity hydraulic shear capacity, it is conducive to the formation of anaerobic granular sludge, improving the effect of the anaerobic reaction, and effectively improving the practicability of the water distribution device, solving the problems of poor mass transfer effect between the water flow and anaerobic sludge, the existence of water distribution dead zones, and the impact on the treatment efficiency during the use of the existing water distribution device.

The main controller can be a conventional known device for control such as a computer, which can be realized through simple programming by technicians in the field.

[0039] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
