Description

Technical Field

[0001] The present application relates to the technical field of anaerobic tanks, and in particular to an anti-clogging anaerobic tank water distributor structure and an anti-clogging method thereof. Background Art

[0002] The sewage treatment anaerobic tank is a device that uses anaerobic microorganisms to decompose organic matter in an oxygen-free environment. It is widely used in the treatment of high-concentration organic wastewater. Its core function is to convert organic matter into methane and carbon dioxide through anaerobic biodegradation, while removing pollutants such as COD, BOD, nitrogen and phosphorus in the sewage, achieving the dual goals of water purification and energy recovery.

[0003] The water distribution system of anaerobic reactors (such as UASB and IC reactors) usually adopts bottom water distribution. Its typical structure includes: a vertically arranged cylindrical tank body with a water distribution pipe assembly arranged at the bottom of the tank body; the water distribution pipe assembly is composed of multiple groups of parallel water distribution pipe units, and the extension direction of each water distribution pipe unit is perpendicular to the axis of the tank body; a water distribution channel is opened at the bottom of the pipe wall of each water distribution pipe, and the opening direction of the water distribution channel is parallel to the axis of the tank body, so that when the wastewater is ejected through the water distribution channel, a flow field is formed that rises along the axis of the tank body, thereby driving the anaerobic activated sludge deposited at the bottom of the tank body to surge upward, realizing efficient contact and mixing of wastewater and sludge.

[0004] Regarding the above-mentioned related technologies, since the opening direction of the water distribution channel is parallel to the axis of the tank body, the suspended matter (such as incompletely precipitated solid particles, fibrous substances) and microbial metabolites (such as extracellular polymers) carried by the wastewater during injection are easily deposited on the inner wall of the water distribution channel. After long-term operation, the effective flow area of ​​the channel is reduced, and the water distribution uniformity is significantly reduced, affecting the treatment efficiency of the reactor; at the same time, the interior of the anaerobic reactor is a harsh environment where high-concentration organic wastewater and anaerobic sludge coexist (pH value fluctuations, presence of toxic substances), and the water distribution channel cannot be desilted under normal operating conditions; the water distribution function can only be restored during overhaul by emptying the reactor, manual cleaning, etc., resulting in long maintenance cycles, high operational complexity, and high downtime costs, so it needs to be improved. Summary of the Invention

[0005] In order to reduce the blockage of the water distribution outlet, reduce the manual cleaning of the water distribution outlet, extend the maintenance cycle, and improve the water distribution efficiency, the present application provides an anti-clogging anaerobic tank water distributor structure and an anti-clogging method thereof.

[0006] The present application provides an anti-clogging anaerobic tank water distributor structure and an anti-clogging method thereof, which adopts the following technical solutions: A blockage-resistant anaerobic tank water distributor structure and a blockage-resistant method thereof, comprising a vertically arranged tank body and a water distribution pipe arranged in the tank body, wherein the water distribution pipe is provided with multiple groups, and the multiple groups of water distribution pipes are arranged at intervals, and a water distribution assembly is rotatably provided at the bottom of the water distribution pipe, and the water distribution assembly is provided in multiple numbers, and the multiple water distribution assemblies are evenly spaced and arranged along the length direction of the water distribution pipe, and a connecting pipe is provided at the bottom of the water distribution pipe, and the water distribution pipe is also provided with a cleaning assembly for cleaning the middle water distribution pipe and an auxiliary assembly for assisting the liquid discharge of the side water distribution pipes; The water distribution assembly includes a rotating rod rotatably connected to the connecting pipe and a water outlet pipe provided on the rotating rod, the water outlet pipe is arranged obliquely toward the bottom of the tank body, and two groups of water outlet pipes are provided, the two groups of water outlet pipes are arranged at both ends of the rotating rod, and the two groups of water outlet pipes are arranged opposite to each other and symmetrically around the center; The auxiliary component includes a first adjusting ring slidably provided on the connecting pipe, a second adjusting ring provided on the rotating rod, and an adjusting member for slidingly adjusting the first adjusting ring; a knocking hammer is rotatably provided on the first adjusting ring, and the knocking hammer is movably fitted with the connection between the water distribution pipe and the connecting pipe, and multiple groups of auxiliary components are evenly spaced on each water distribution pipe, and the first adjusting rings on the same water distribution pipe are staggered in height, and adjacent knocking hammers on the water distribution pipe knock on the water distribution pipe alternately; The cleaning assembly includes a third adjustment ring slidably arranged on the connecting pipe and a fourth adjustment ring arranged on the rotating rod. The water distribution pipe is provided with an auxiliary liquid outlet, and a blocking member is provided at the auxiliary liquid outlet. When the water outlet pipe is blocked, the blocking member opens the auxiliary liquid outlet; When the water outlet pipe is opened, the blocking member blocks the auxiliary liquid outlet.

[0007] By adopting the above technical solution, during normal anaerobic treatment, the wastewater enters the rotating rod through the connecting pipe at the bottom of the water distribution pipe and is sprayed out from the outlet pipe. Since the outlet pipe is arranged at an angle and there are two groups of outlet pipes, the two groups of outlet pipes spray water, and the water flow drives the outlet pipes to rotate. The rotation of the outlet pipes disturbs the sludge in the tank, thereby achieving efficient and uniform mixing of the wastewater and the sludge, and improving the efficiency of subsequent anaerobic treatment.

[0008] At the same time, during the continuous anaerobic treatment process, as the sewage in the water distribution pipe continues to be sprayed out, when solid impurities in the sewage gather at the corners of the water distribution pipe, the corners of the water distribution pipe are knocked by rotating the set knocking hammer, thereby reducing the blockage of the water distribution pipe by solid impurities.

[0009] When the side water distribution pipe is difficult to mix easily due to sludge accumulation, the auxiliary liquid outlet is opened through the sealing piece. The wastewater sprayed from the auxiliary liquid outlet disperses the sludge on the side of the tank body, thereby causing the water distribution pipe to rotate and reducing blockage of the water distribution pipe.

[0010] Optionally, the adjusting member includes an adjusting sleeve fixedly mounted on the connecting tube, a bidirectional thread is provided on the outer peripheral wall of the adjusting sleeve, the first adjusting ring is threadedly mounted on the adjusting sleeve, a fixing sleeve is provided on the connecting tube, the knocking hammer is rotatably connected to the fixing sleeve, a tightening block is provided at the end of the knocking hammer away from the rotating rod, a limiting block is provided on the first adjusting ring, the limiting block is movably fitted with the tightening block, and an elastic return member is provided at the rotating shaft of the knocking hammer.

[0011] By adopting the above technical solution, when the middle water distribution pipe rotates, it drives the second adjusting ring to rotate, and the second adjusting ring drives the first adjusting ring to rotate. Since the first adjusting ring is threadedly sleeved on the adjusting sleeve, as the first adjusting ring rotates, the first adjusting ring rises and falls on the adjusting sleeve, and the first adjusting ring drives the limit block to rise and fall, so that the limit block fits and tightens the tightening block, so that the knocking hammer rotates, and the connection between the water distribution pipe and the connecting pipe is knocked, thereby reducing the problem of the water distribution pipe being blocked by the accumulation of sand and gravel when the wastewater flows. At the same time, when the first adjusting ring slides in the direction away from the knocking hammer, the knocking hammer automatically rotates in the direction away from the connecting pipe under the action of the elastic return member until the next time the first adjusting ring slides in the direction close to the knocking hammer, thereby performing a knock.

[0012] Optionally, the hammer head of the striking hammer is made of elastic material, and the end side where the limiting block fits with the pressing block is spherical.

[0013] By adopting the above technical solution, since the striking hammer is made of elastic material, each time the striking hammer is driven to rotate, the striking hammer made of elastic material will strike the connecting pipe back and forth under the action of its own material. Therefore, when the second adjusting ring rotates at high speed, the striking hammer vibrates at a high frequency under the buffering effect of its own elastic material, but with a small amplitude, thereby achieving vibration of the connecting pipe, making it difficult for small solid impurities to remain in the corners of the water distribution pipe.

[0014] When the second adjustment ring rotates at a low speed, the hammer itself rotates with a large amplitude, thereby achieving low-frequency and large-amplitude knocking on the corners of the water distribution pipe, making it difficult for large particles of solid impurities to remain in the corners of the water distribution pipe, thereby reducing blockage of the water outlet pipe.

[0015] The spherical surface is provided to improve the smoothness of the tight fit between the limit block and the tightening block, and at the same time the spherical surface side is treated for wear resistance to extend the service life of the striking hammer.

[0016] Optionally, the blocking member includes a blocking plate slidably sleeved on the water distribution pipe, and the blocking plate movably corresponds to the auxiliary liquid outlet, the third adjusting ring is provided with an adjusting block, and the blocking plate is also provided with an adjusting groove, the adjusting block is movably inserted into the adjusting groove, the side wall of the adjusting groove is inclined, and the adjusting block and the inclined side wall of the adjusting groove are movably fitted and tightly pressed, the blocking plate is elastically slidably arranged on the water distribution pipe, and a speed member for adjusting the distance between the third adjusting ring and the fourth adjusting ring is provided between the third adjusting ring and the fourth adjusting ring; When the speed of the fourth adjustment ring is faster, the speed member adjusts the distance between the third adjustment ring and the fourth adjustment ring to be smaller; When the rotation speed of the fourth adjusting ring is slower, the distance between the third adjusting ring and the fourth adjusting ring adjusted by the rotation speed member is larger.

[0017] By adopting the above technical solution, when anaerobic treatment is carried out, the fourth adjustment ring rotates with the water distribution pipe, and its rotation speed is consistent with the rotation speed of the water distribution pipe, so that the rotation speed of the fourth adjustment ring is faster as the rotation speed of the water distribution pipe. At this time, the speed component adjusts the distance between the third adjustment ring and the fourth adjustment ring to be smaller, so that the third adjustment ring slides toward the direction of the fourth adjustment ring. At this time, the adjustment block is separated from the adjustment groove. At this time, the sealing plate slides toward the direction of the auxiliary liquid outlet under the action of the elastic restoring force, thereby achieving the sealing of the auxiliary liquid outlet.

[0018] When the water distribution pipe is blocked, the rotation speed of the water distribution pipe is slow, and the rotation speed of the fourth adjustment ring is slow. The speed member adjusts the distance between the third adjustment ring and the fourth adjustment ring to increase, so that the third adjustment ring slides in the direction away from the fourth adjustment ring. At this time, the adjustment block is inserted into the adjustment groove, so that the adjustment block fits tightly against the inclined side of the adjustment groove, thereby realizing the sliding adjustment of the sealing plate, so that the sealing plate opens the auxiliary liquid outlet, thereby realizing auxiliary discharge of wastewater, and the wastewater sprayed from the auxiliary liquid outlet disperses the sludge, thereby reducing the blockage of the water outlet pipe.

[0019] Optionally, the speed member includes an adjusting spring provided between the third adjusting ring and the fourth adjusting ring, the adjusting spring movably fits and presses against the third adjusting ring, a first support rod is provided on the third adjusting ring, a second support rod is provided on the fourth adjusting ring, an end of the first support rod away from the third adjusting ring is rotatably connected to an end of the second support rod away from the fourth adjusting ring, and a counterweight is provided at the connection between the first support rod and the second support rod; When the fourth adjustment ring is stationary or rotates at a slow speed, the adjustment spring presses against the third adjustment ring to insert the adjustment block into the adjustment slot; When the fourth adjustment ring rotates at a faster speed, the third adjustment ring slides toward the fourth adjustment ring, and the blocking plate blocks the auxiliary liquid outlet.

[0020] By adopting the above-mentioned technical solution, when the fourth adjusting ring rotates with the water distribution pipe, the third adjusting ring is driven to rotate under the action of the first support rod and the second support rod. At this time, the counterweight block arranged at the connection between the first support rod and the second support rod rotates, and the counterweight block moves in the direction away from the connecting pipe under the action of centrifugal force when the third adjusting ring and the fourth adjusting ring rotate. The faster the rotation speed of the fourth adjusting ring, the more the counterweight block moves in the direction away from the connecting pipe, so that the first support rod and the second support rod rotate closer to the direction perpendicular to the connecting pipe, driving the third adjusting ring to slide toward the fourth adjusting ring.

[0021] When the fourth adjusting ring rotates at a slower speed, the centrifugal force exerted on the counterweight block is smaller, so that the rotation angle of the first support rod and the second support rod is closer to being arranged parallel to the length direction of the connecting pipe. Under the action of the adjusting spring, the third adjusting ring moves in the direction away from the fourth adjusting ring, so that the adjusting block is inserted into the adjusting groove, and the adjusting block is pressed against the inclined side of the adjusting groove, thereby realizing the sliding adjustment of the sealing plate, so that the sealing plate opens the auxiliary liquid outlet, and the wastewater is sprayed out from the auxiliary liquid outlet, thereby reducing the blockage of the outlet pipe by sludge.

[0022] And due to the rotation of the middle water outlet pipe, in the initial state, and because there are fewer water outlet pipes on the side water distribution pipes, the water outlet pipes on the side water distribution pipes are not easy to rotate under the action of sludge. In the initial state, the adjustment spring presses against the third adjustment ring to slide, and the third adjustment ring drives the adjustment block to press against the adjustment groove, so that the sealing plate opens the auxiliary liquid outlet. In the initial state, the sludge is flushed away, thereby facilitating the rotation of the water outlet pipe.

[0023] Under continuous anaerobic action, sludge will gather toward the sides. Therefore, as the sludge gathers, the water distribution pipe is not easy to rotate. At this time, the sealing plate also opens the auxiliary liquid outlet, thereby reducing the impact of sludge gathering on the sides on the water outlet pipe.

[0024] Optionally, a plurality of auxiliary liquid outlets are provided, and the plurality of auxiliary liquid outlets are evenly spaced around the circumference of the water distribution pipe, and the sealing plate is slidingly sealed with the water distribution pipe. The opening direction of the auxiliary liquid outlet is inclined to the radial direction of the water distribution pipe, and the sealing plate is annularly sleeved on the water distribution pipe, and an elastic protrusion is provided on the sealing plate, and the elastic protrusion is movably engaged with the auxiliary liquid outlet.

[0025] By adopting the above technical solution, multiple auxiliary liquid outlets are opened. When the auxiliary liquid outlets are opened, wastewater is sprayed out at an angle from the auxiliary liquid outlets, thereby generating a vortex that is perpendicular to the vortex direction generated by the rotation of the water distribution pipe, thereby increasing the stirring rate of the sludge, and further increasing the stirring rate of the sludge at the side of the tank body.

[0026] At the same time, the elastic protrusions arranged on the blocking plate realize sealing and clamping when blocking the auxiliary liquid outlet.

[0027] Optionally, a microbubble generator and a microporous aeration tube connected to the microbubble generator are provided at the bottom of the tank body. The microporous aeration tubes are provided in multiple groups, and the multiple groups of microporous aeration tubes correspond one-to-one to the multiple groups of water distribution pipes. A flow meter is provided in the water distribution pipe, and the flow meter is electrically connected to the microbubble generator.

[0028] By adopting the above technical solution, the water flow rate is monitored in real time through the flow meter, and the data is fed back to the microbubble generator to form a closed-loop control system. The microbubble group and the designed flow rate of the water distribution pipe are coordinated to form a suitable suspension environment, so that the granular sludge can remain stably suspended and the sludge can be reduced. Compaction and sedimentation of the sludge are reduced.

[0029] The micron-sized bubbles produced by the microporous aeration tubes have a large specific surface area, forming a gas-liquid two-phase flow at the bottom of the anaerobic tank, significantly improving the mass transfer efficiency between the substrate and methanogens, and accelerating the hydrolysis and acidification process of complex organic matter.

[0030] This application also provides an anaerobic tank water distributor anti-blocking method, which adopts the following technical solution: S1, normal operation. When the wastewater is anaerobic treated normally, the wastewater in the water distribution pipe is ejected through the outlet pipe. Under the thrust of the water flow, the outlet pipe is driven to rotate. The water flow forms a vortex that drives the sludge in the tank to stir, forming a uniformly mixed wastewater-sludge mixture. At the same time, during the rotation of the outlet pipe, the outlet pipe is struck and vibrated with a high frequency and small amplitude by a hammer to reduce the amount of sludge in the wastewater. S2, water pipe blockage. When the side outlet pipe is blocked, it is often because the sludge accumulation on the side is higher than that in the middle. Therefore, the auxiliary outlet is used to spray the sludge on the side to disperse it, and the water flow through the auxiliary outlet reduces the blockage of the outlet pipe by the sludge on the side. S3, water pipe blockage. When the water outlet pipe in the middle is blocked, it is often due to the blockage of sand and gravel in the wastewater. The water distribution pipe can be unblocked by using a hammer to perform high-frequency low-amplitude / low-frequency large-amplitude knocking according to the rotation speed of the water outlet pipe to reduce the blockage of the water distribution pipe.

[0031] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the water distribution pipe and the rotating outlet pipe, when the wastewater is discharged, the outlet pipe rotates to form a vortex to disperse the sludge, thereby reducing the blockage of the middle outlet pipe by the sludge. At the same time, the percussion hammer installed on the middle water distribution pipe rotates to knock the connecting pipe to reduce the blockage of sand and gravel at the bend of the water distribution pipe; 2. By rotating the water outlet pipe and opening the auxiliary liquid outlet on the side water distribution pipe, when the side water distribution pipe is blocked, the auxiliary liquid outlet will disperse the sludge, thereby reducing the blockage of the water outlet pipe; 3. At the same time, the third adjusting ring, the fourth adjusting ring and the adjusting block are provided, and as the rotation speed of the fourth adjusting ring changes, the blocking plate is slidably adjusted to open or block the auxiliary liquid outlet.

[0034] The following is combined with Figure 1-4 This application is described in further detail.

[0035] The present application embodiment discloses an anti-clogging anaerobic tank water distributor structure. Figure 1A clogging-resistant anaerobic tank water distributor structure includes a vertically arranged tank body 1, in which a plurality of water distribution pipes 11 are provided. The water distribution pipes 11 are evenly spaced along the cross-sectional diameter direction of the tank body 1. A connecting pipe 12 is connected to the bottom of each water distribution pipe 11, and the water distribution pipe 11 is rotatably connected to a plurality of water distribution components 2 at the connecting pipe 12. The water distribution components 2 are arranged at equal intervals along the length direction of the water distribution pipe 11. A microbubble generator 5 is also provided on the outside of the tank body 1. A plurality of microporous aeration pipes 51 are provided on the bottom side of the water distribution pipe 11 in the tank body 1. The microporous aeration pipes 51 correspond one-to-one to the water distribution pipe 11. A flow meter 52 is installed in the water distribution pipe 11. The flow meter 52 is electrically linked to the microbubble generator 5.

[0036] Reference Figure 1 and Figure 2 The water distribution assembly 2 includes a rotating rod 21 rotatably connected to the lower end of the connecting pipe 12. Two sets of outlet pipes 22 are symmetrically positioned at either end of the rotating rod 21. The outlet pipes 22 are arranged obliquely toward the bottom of the tank body 1 and are arranged symmetrically around the center of the tank body 1. After wastewater enters the connecting pipe 12 through the water distribution pipe 11, it is distributed to the outlet pipes 22 by the rotating rod 21. The oblique layout and reverse injection of the outlet pipes 22 create a rotational torque that drives the rotating rod 21 to rotate about the axis of the connecting pipe 12. This, in turn, drives the outlet pipes 22 to form a cyclonic flow field within the tank body 1, stirring the sludge and wastewater for uniform mixing.

[0037] At the same time, an auxiliary component 3 for assisting the water distribution pipe 11 to discharge liquid is also provided on the water distribution pipe 11. Figure 2 and Figure 3 The auxiliary component 3 includes a first adjustment ring 31 that is slidably sleeved on the connecting pipe 12, a second adjustment ring 32 that is fixed to the rotating rod 21, and an adjustment member 34. A limit rod is fixedly connected to the second adjustment ring 32, and the limit rod slides through the first adjustment ring 31. The adjustment member 34 includes an adjustment sleeve 341 fixed to the connecting pipe 12, and a bidirectional thread is provided on the outer peripheral wall of the adjustment sleeve 341. The first adjustment ring 31 is threadedly sleeved on the adjustment sleeve 341. A fixed sleeve 342 is fixedly connected to the connecting pipe 12, and a knocking hammer 33 is rotatably connected to the fixed sleeve 342. The hammer head of the knocking hammer 33 is made of elastic rubber material, one end of which is movably fitted with the outer wall of the water distribution pipe 11 or the connecting pipe 12, and the other end is provided with a tightening block 343. A limit block 344 is provided on the first adjustment ring 31, and the limit block 344 is in spherical contact with the end face of the tightening block 343. When the rotating rod 21 rotates, the second adjusting ring 32 rotates synchronously. The second adjusting ring 32 drives the first adjusting ring 31 to rotate through the limiting rod. Since the first adjusting ring 31 is threadedly engaged with the adjusting sleeve 341, the first adjusting ring 31 is lifted and lowered axially along the connecting pipe 12.

[0038] When the first adjustment ring 31 rises, the limit block 344 pushes the abutting block 343, causing the hammer 33 to rotate about the axis and strike the outer wall of the connecting pipe 12. When the first adjustment ring 31 descends, the hammer 33 returns to its original position under the action of the elastic return member 345. The high-frequency, low-amplitude hammering reduces the adhesion of fine impurities, while the low-frequency, high-amplitude hammering removes large particles that clog the pipe.

[0039] In the initial state, and because there are fewer outlet pipes 22 on the side water distribution pipe 11, the outlet pipe 22 on the side water distribution pipe 11 is not easy to rotate under the action of sludge, so a cleaning component 4 is also provided on the side water distribution pipe 11. Figure 3 and Figure 4 The cleaning assembly 4 includes a third adjustment ring 41 that slides over the connecting pipe 12, a fourth adjustment ring 42 fixed to the rotating rod 21, and a speed member 45. The water distribution pipe 11 has multiple auxiliary liquid outlets 43 circumferentially defined. These auxiliary liquid outlets 43 are slidably sealed with an annular sealing plate 441. The inner wall of the sealing plate 441 has elastic protrusions that engage with the auxiliary liquid outlets 43. An adjustment block 442 is provided on the third adjustment ring 41. The sealing plate 441 defines an inclined adjustment slot 443. The adjustment block 442 is movably inserted into the adjustment slot 443 and engages with the inclined sidewall.

[0040] The speed member 45 includes an adjustment spring 451 connecting the third adjustment ring 41 and the fourth adjustment ring 42, a first support rod 452, a second support rod 453, and a counterweight 454. One end of the first support rod 452 is fixed to the third adjustment ring 41, and one end of the second support rod 453 is fixed to the fourth adjustment ring 42. The other ends of the two rods are rotatably connected and mounted with the counterweight 454. When the speed of the water distribution pipe 11 increases, the counterweight 454 moves outward under the action of centrifugal force, driving the first support rod 452 and the second support rod 453 to be arranged perpendicular to the connecting pipe 12, and the distance between the third adjustment ring 41 and the fourth adjustment ring 42 is reduced. The adjustment block 442 disengages from the adjustment groove 443, and the sealing plate 441 blocks the auxiliary liquid outlet 43 under the elastic restoring force; when the speed of the water distribution pipe 11 decreases, the counterweight 454 retracts, and the adjustment spring 451 pushes the third adjustment ring 41 away from the fourth adjustment ring 42. The adjustment block 442 is inserted into the adjustment groove 443 and slides along the inclined side wall, driving the sealing plate 441 to open the auxiliary liquid outlet 43, and the wastewater is ejected from the inclined auxiliary liquid outlet 43 to form a vertical vortex, which disperses the sludge on the side.

[0041] A flowmeter 52 within the water distribution pipe 11 monitors the inlet flow in real time, feeding this data back to the microbubble generator 5. The microbubble generator 5 adjusts the amount of bubbles generated in the microporous aeration tube 51 based on the flow rate to maintain a stable gas-liquid two-phase flow field at the tank bottom. The micron-sized bubbles (50-200μm) generated by the microporous aeration tube 51 form a uniform air cushion at the tank bottom, enhancing mass transfer efficiency between the substrate and the methanogens. Furthermore, they work in conjunction with the swirling flow in the water distribution pipe 11 to keep sludge particles suspended (the lateral variation in sludge concentration gradient is ≤5% and the vertical variation is ≤10%), preventing sludge compaction.

[0042] The embodiment of the present application also discloses a method for preventing clogging of an anti-clogging anaerobic tank water distributor, comprising the following steps: S1, normal operation. When the wastewater is normally anaerobically treated, the wastewater flow in the water distribution pipe 11 is ejected through the outlet pipe 22. Under the thrust of the water flow, the outlet pipe 22 is driven to rotate. The water flow forms a vortex that drives the sludge in the tank body 1 to stir, forming a uniformly mixed wastewater-sludge mixture. At the same time, during the rotation of the outlet pipe 22, the outlet pipe 22 is struck and vibrated with a high frequency and a small amplitude by a hammer 33 to reduce the amount of wastewater in the wastewater; S2: When the side outlet pipe 22 is blocked, it is often because the sludge accumulation on the side is higher than that in the middle. Therefore, the auxiliary liquid outlet 43 is used to spray the sludge on the side, and the water flow through the auxiliary liquid outlet 43 reduces the blockage of the outlet pipe 22 by the sludge on the side. S3, the water pipe is blocked. When the water outlet pipe 22 in the middle is blocked, it is often due to the blockage of the water outlet pipe 22 by gravel in the wastewater. The water outlet pipe 22 is unblocked by the hammer 33 with high frequency and low amplitude / low frequency and large amplitude according to the rotation speed of the water outlet pipe 22, thereby reducing the blockage of the water distribution pipe 11.

[0043] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.

8. A method for preventing clogging of an anaerobic tank water distributor, based on the anti-clogging anaerobic tank water distributor structure of claim 7, characterized in that: The following steps are involved: S1, normal operation. When the wastewater is anaerobic treated normally, the wastewater in the water distribution pipe (11) is ejected through the outlet pipe (22). Under the thrust of the water flow, the outlet pipe (22) is driven to rotate. The water flow forms a vortex to stir the sludge in the tank (1), forming a uniformly mixed wastewater-sludge mixture. At the same time, during the rotation of the outlet pipe (22), the outlet pipe (22) is struck and vibrated with a high frequency and a small amplitude by the hammer (33), thereby reducing the wastewater; S2, water pipe blockage. When the side outlet pipe (22) is blocked, it is often because the sludge accumulation on the side is higher than that in the middle. Therefore, the sludge on the side is dispersed by spraying through the auxiliary liquid outlet (43). The water flow through the auxiliary liquid outlet (43) reduces the blockage of the outlet pipe (22) by the sludge on the side. S3, water pipe blockage. When the water outlet pipe (22) in the middle is blocked, it is often due to the blockage of the water outlet pipe (22) by gravel in the wastewater. The water distribution pipe (11) is unblocked by performing high-frequency low-amplitude / low-frequency high-amplitude knocking according to the rotation speed of the water outlet pipe (22) through the knocking hammer (33), thereby reducing the blockage of the water distribution pipe (11).
