Description

Technical Field

[0001] The utility model relates to the technical field of water distribution devices, and in particular to an anaerobic tank water distribution device. Background Art

[0002] The anaerobic tank body is a highly efficient multi-stage internal circulation anaerobic reaction tank with both water distribution and hydraulic stirring functions. Its design makes the flow distributed to each point the same, ensuring that the water intake per unit area is basically the same. The anaerobic tank body occupies a small area, has a high organic load, is more impact-resistant, has more stable performance, and is simpler to operate and manage. The anaerobic tank body is suitable for the treatment of high-concentration organic wastewater.

[0003] The working principle of the three-phase separator inside the anaerobic tank is mainly based on the metabolic action of microorganisms under anaerobic conditions. When sewage enters the anaerobic reactor, it comes into contact with the anaerobic sludge inside. The microorganisms decompose organic matter to produce biogas. The three-phase separator effectively separates biogas, liquid and solid sludge. The biogas is collected and discharged through the gas collection hood for energy utilization. The liquid part is discharged or reused after further treatment. The solid sludge is discharged through the sludge discharge system at the bottom of the separator for subsequent treatment. When the anaerobic tank treats high-concentration wastewater or sewage, since the sewage contains impurities, it cannot be completely reacted into the above three types. If some impurities cannot be decomposed, it may cause the dirt inside the three-phase separator to clog, reducing the sludge flow of the sewage treatment system. The solid sludge at the bottom of the anaerobic tank and the sludge or impurities on the side walls accumulate and clog the three-phase separator. The clogged three-phase separator will reduce the sludge suspension of the sewage treatment system. The water pipes and the inside of the anaerobic tank need to be cleaned to separate the mixed organic matter and sludge, thus affecting the separation and sludge removal effect.

[0025] In this embodiment, the water distribution assembly includes an inlet pipe 101, a downpipe 102, an uppipe 103, an uppipe 2 104 and an outlet pipe 105.

The mud discharge port 201 is provided on the outer wall of the anaerobic tank body 1 , and the mud discharge cover plate 202 is detachably connected to the mud discharge port 201 .

[0027] In this embodiment, the water storage cleaning component includes a water tank 301, a motor 302, a water supply pipe 303, a water spray conduit 304, a nozzle 305, a connecting rod 306, a water injection pipe 307 and a valve 308. Two motor 302 mounting ports are provided on the outer wall of the water tank 301. The motor 302 is fixedly installed at each of the motor 302 mounting ports.

[0028] It should be added that the anaerobic tank used in the present invention is the IC anaerobic tank body 1. Its working principle is that the wastewater enters the mixing area at the bottom of the reactor after adjustment, and is fully mixed and contacted with the internal circulating sludge. The mixed liquid undergoes an anaerobic reaction in the winding flow channel, and the organic matter is degraded to produce biogas. The mixed liquid after the reaction flows into the lower sedimentation area for solid-liquid separation. The precipitated sludge is pumped to the top reaction area by the internal circulation pump, mixed with the new wastewater and then enters the reaction area. The biogas generated after the reaction is collected and discharged from the top, and the treated water flows out from the top of the reactor. The unreacted sludge and some impurities inside will cause blockage and accumulation in the anaerobic tank water distribution device, which requires manual cleaning on a regular basis.

[0029] In summary, the working principle of the anaerobic tank water distribution device is as follows: after the anaerobic tank body 1 water distribution device works, some sludge will remain inside. In order not to affect the next reaction effect, the anaerobic tank body 1 is first stopped, the valve 308 is opened, and the water injection pipe 307 is used to inject water into the water supply pipe 303 through the connecting rod 306. After the water injection is completed, the valve 308 is closed to stop the water injection, and the motor 302 is started to drive the water supply pipe 303 to rotate. The water is rotated and sprayed out through the nozzle 305 on the water supply pipe 303 to spray water to clean the inside of the anaerobic tank body 1. After the first water spraying, most of the sludge can be loosened, and the sludge at a high position in the anaerobic tank body 1 will slide onto the solid bed 5 through the primary separator 3 and the secondary separator 4. Since the solid bed 5 is funnel-shaped 7, it will slide to the bottom of the anaerobic tank body 1 by itself, and will slide to the mud discharge port 201 through the design of the slope surface 6 of the inner bottom wall, and will not accumulate in various places at the bottom of the anaerobic tank body 1. If residual stubborn sludge is still observed, a second water spraying cleaning can be performed. When the water spraying cleaning is completed, the motor 302 is turned off, the mud discharge cover 202 is opened, and the sludge accumulated at the mud discharge port 201 is cleaned.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
