[0002] Anaerobic reactor is a widely used equipment for wastewater treatment. It mainly decomposes organic pollutants into methane, carbon dioxide and other inorganic substances through the metabolic activities of anaerobic microorganisms in an oxygen-free environment. Anaerobic reactors have the advantages of low energy consumption, high treatment efficiency and low sludge production, so they have been widely used in the fields of industrial wastewater and domestic sewage treatment. However, in actual application, anaerobic reactors also face some challenges, one of which is the uneven distribution of wastewater in the reactor.

[0022] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0023] like Figure 1-4 As shown, an anaerobic reactor water distribution device includes an anaerobic reactor tank body 1, a wastewater supply group is fixedly connected to the anaerobic reactor tank body 1, the wastewater supply group is connected to a porous water outlet unit located inside the anaerobic reactor tank body 1, and a vertical adjustment group connected to the water outlet unit is fixedly connected to the anaerobic reactor tank body 1. At this time, when water is introduced into the anaerobic reactor tank body 1 through the wastewater supply group and the porous water outlet unit, the wastewater entering the anaerobic reactor tank body 1 will form a wastewater area, and the vertical adjustment group can drive the water outlet unit to move to the middle position of the wastewater area, so that the wastewater output by the water outlet unit is roughly the same distance from the top and bottom of the wastewater area inside the anaerobic reactor tank body 1, so that the wastewater output from the porous water outlet unit to the inside of the anaerobic reactor tank body 1 is more evenly distributed, reducing dead angles for water inlet.

[0024] like Figure 2-3 As shown, the porous water outlet unit includes multiple porous water outlet racks connected to the wastewater supply group, and the porous water outlet rack located on the uppermost side is connected to the vertical adjustment group, and the vertical adjustment group can drive the uppermost porous water outlet rack to move vertically.

[0025] Two adjacent porous water outlet racks are connected by a height adjusting member. At this time, the distance between the two adjacent porous water outlet racks is adjusted by the height adjusting member, so that multiple porous water outlet racks are evenly arranged inside the wastewater area, so that multiple layers of evenly distributed porous water outlet racks can add wastewater to the wastewater area more evenly.

[0026] Among them, Figure 2-3 As shown, the porous water outlet rack includes an annular flow pipe 5 connected to the wastewater supply group. The outer side of the annular flow pipe 5 is fixedly connected to a plurality of liquid outlet pipes 6 arranged in an annular array with the center of the annular flow pipe 5. At this time, the wastewater input by the wastewater supply group will enter the interior of the annular flow pipe 5, and then be discharged through the plurality of liquid outlet pipes 6, so as to be discharged more evenly.

[0027] Among them, Figure 2-4 As shown, the wastewater supply group includes a lifting pump 9 fixedly connected to the outside of the anaerobic reactor tank 1. The lifting pump 9 is connected to multiple annular circulation pipes 5 through a hose 8. It can be arranged in series or in parallel, as long as it can supply water to the inside of the annular circulation pipe 5 and can adapt to the movement of the annular circulation pipe 5.

[0028] Among them, Figure 2-4As shown, the height adjustment member includes a plurality of slides 3, and the plurality of slides 3 are respectively fixedly connected to a plurality of annular circulation tubes 5, and an automatic reset member 4 is installed between each adjacent slide 3. The automatic reset member 4 can be an elastic rope or a return spring. When the uppermost annular circulation tube 5 and the lowermost annular circulation tube 5 are limited, the annular circulation tube 5 located in the middle position will be automatically adjusted under the action of the automatic reset member 4, so that the plurality of annular circulation tubes 5 are evenly distributed vertically.

[0029] Another automatic reset member 4 is installed between the lowermost slide 3 and the inner wall of the lower side of the anaerobic reactor tank body 1. Through the action of the automatic reset member 4, a certain distance can be maintained between the lowermost annular circulation pipe 5 and the bottom wall of the anaerobic reactor tank body 1, so that the annular circulation pipe 5 is evenly distributed.

[0030] When the automatic reset member 4 is a return spring, Figure 2-4 As shown, the vertical adjustment group includes a vertical edge rod 2 fixedly connected to the inside of the anaerobic reactor tank body 1 and a vertical electric push rod 7 fixedly connected to the upper end of the anaerobic reactor tank body 1. Multiple slides 3 are vertically slidably connected to the vertical edge rod 2, and the output end of the vertical electric push rod 7 is fixedly connected to the slide 3 located on the uppermost side. At this time, the slide 3 can be driven to move vertically by starting the vertical electric push rod 7, thereby adjusting the position of the slide 3.

[0031] At the same time, in order to automatically adjust the position of the annular flow pipe 5 during use, the anaerobic reactor tank 1 is fixedly connected with a control host and a liquid level detection device 10 located on the upper side of the anaerobic reactor tank 1. The liquid level detection device 10 can be an infrared distance measuring device or other distance measuring devices.

[0032] The vertical electric push rod 7 and the liquid level detection device 10 of the vertical adjustment group are electrically connected to the control host. At this time, the liquid level height of the wastewater area inside the anaerobic reactor tank 1 is measured by the liquid level detection device 10 to determine the height of the wastewater area, and then the position of the annular circulation pipe 5 is determined according to the height of the wastewater area, and then the height of the uppermost slide 3 and the annular circulation pipe 5 is adjusted by the vertical electric push rod 7. When the height of the uppermost annular circulation pipe 5 is determined, the height of the remaining annular circulation pipes 5 can be automatically adjusted by the automatic reset member 4.

[0033] The working principle of the utility model is as follows: the lifting pump 9 is started to inlet wastewater, and the wastewater will sequentially pass through the hose 8, the annular flow pipe 5, and the liquid outlet 6 into the interior of the anaerobic reactor tank 1, and then the liquid level height of the wastewater area inside the anaerobic reactor tank 1 is detected by the liquid level detection device 10 to determine the height of the wastewater area;

[0034] When the height of the wastewater area is determined, the estimated heights of the multiple annular circulation pipes 5 can be calculated based on the height of the wastewater area, so that the multiple annular circulation pipes 5 can be evenly distributed. After the calculation is completed, the height of the uppermost slide 3 and the annular circulation pipe 5 is adjusted by the vertical electric push rod 7. When the height of the uppermost annular circulation pipe 5 is determined, the heights of the remaining annular circulation pipes 5 can be automatically adjusted by the automatic reset part 4, so that the multiple annular circulation pipes 5 are evenly distributed in the wastewater area.

[0035] In summary, the technical solution divides the porous water outlet unit into multiple layers of height-adjustable porous water outlet frames, which can adjust the water outlet position of the porous water outlet frames, so that multiple porous water outlet frames can evenly discharge water inside the wastewater area of ​​the anaerobic reactor tank body 1, so that the wastewater output from the porous water outlet unit to the inside of the anaerobic reactor tank body 1 is more evenly distributed, reducing dead corners of water inlet.

[0036] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
