Description

Technical Field

[0001] The present application belongs to the technical field of sewage treatment, and specifically relates to a water distributor for anaerobic reaction equipment. Background Art

[0002] As the most important component system of the anaerobic reactor, the water distribution tank has become one of the important factors affecting the entire wastewater treatment process. Once uneven water distribution such as short-flow and blind spots occur, it will lead to local accumulation of sludge. Long-term local accumulation of sludge will cause tank acidification, seriously affecting the stable operation of the system.

[0003] In order to improve the uniformity of water distribution and reduce sludge accumulation, existing water distribution tanks usually adopt multi-point spraying to evenly spread the sludge in the water distribution tank. However, there will still be accumulation of mud and dirt, which requires manual cleaning after work. It is difficult to clean the dead corners at the corners, and the acidification of the tank body cannot be avoided. Utility Model Content

[0004] The present application provides a water distributor for anaerobic reaction equipment to solve the technical problem of acidification of the water distribution tank due to scaling in the anaerobic reactor.

[0005] The technical solution adopted in this application is:

[0006] A water distributor for anaerobic reaction equipment comprises a water distribution tank and a spray unit, wherein the water distribution tank comprises a tank body, wherein an annular guide slope is arranged in the tank body, wherein the annular guide slope gradually slopes downward from the outer edge to the inner edge, and a recovery port is arranged in the center of the annular guide slope; wherein the spray unit comprises a spray structure, wherein the spray structure is arranged as a whole above the annular guide slope, wherein the spray structure comprises a water outlet pipe and a water distribution nozzle connected to the water outlet pipe, wherein the water distribution nozzle is provided with a water spray port opening toward the annular guide slope.

[0007] The water distributor for anaerobic reaction equipment of the present application also includes the following additional technical features:

[0008] The spray structure includes a plurality of water outlet pipes, which are distributed on the same horizontal plane and located at positions of the same height as the tank body.

[0009] Each of the water outlet pipes is connected to two of the water distribution nozzles.

[0010] The projection of at least some of the multiple water distribution nozzles on the horizontal plane falls on a circle coaxial with the annular guide slope.

[0011] The distance between any two adjacent water distribution nozzles whose projections fall on a circle coaxial with the annular guide slope is equal.

[0012] The spray unit includes a rotating member, and the rotating member controls the water distribution nozzle to rotate in a direction parallel to the guiding inclined surface.

[0013] It also includes a water distribution bag for supplying water to the water outlet pipeline, and the water distribution bag is connected to the spray structure through a water distribution pipe.

[0014] The water distribution bag is located at the side of the tank body, and a through hole for the water distribution pipe to pass through is opened on the side wall of the tank body. The water distribution pipe passes through the through hole and passes through the tank body in a horizontal direction.

[0015] The annular guiding inclined surface is integrally formed with the tank body.

[0016] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0017] 1. The water distribution tank of the present application includes a tank body provided with an annular guide slope and a spray structure above the annular guide slope, the spray structure can spray water to the annular guide slope through the water spray port on the water distribution nozzle, so that the sludge on the annular guide slope is fully mixed with the water, the sludge on the annular guide slope is vertically displaced under the action of its own gravity, and is displaced in a direction parallel to the tangent of the annular guide slope under the impact of the water spray, that is, the sludge on the annular guide slope is spirally moved toward the recovery port under the combined action of the vertical force and the lateral force, so that the sludge and water are fully mixed, and the sludge can slide down to the recovery port under the action of its own weight, thereby avoiding the sludge from being hidden in the water distribution tank, saving the operation of cleaning the sludge in the water distribution tank after the water distribution work is completed, and effectively reducing the occurrence of acidification caused by the sludge hiding for too long in the water distribution tank.

[0018] 2. As a preferred embodiment of the present invention, the number of water outlet pipes is set to be multiple, which increases the spraying area of ​​the spray structure, so that the sludge on the annular guide slope can be more evenly spread and fully mixed with water, reducing the occurrence of insufficient reaction caused by the sludge being unable to contact with water, which helps to improve the water distribution efficiency of the water distribution tank, thereby improving the reaction efficiency of the anaerobic reactor; and multiple water outlet pipes are distributed on the same horizontal plane, so that the vertical heights of each water outlet are consistent, avoiding the different heights of the water outlet pipes causing the water flow sprayed from the water outlet located above to be blocked by the water outlet pipe located below, thereby improving the uniformity and consistency of the water spray.

[0019] 3. As a preferred embodiment of the present invention, the projection of at least some of the multiple water distribution nozzles on the horizontal plane falls on a circle coaxial with the annular guide slope, so that the sludge can be moved in the same direction, that is, the tangent direction of the concentric circles under the spreading action of the water distribution nozzles, reducing the occurrence of interactive collisions of the sludge under the action of the water distribution nozzles located at different positions, thereby ensuring the consistency of the sludge movement direction and helping to improve the water distribution efficiency of the water distribution tank.

[0020] 4. As a preferred embodiment of the utility model, the water distribution bag is arranged on the side of the tank body, and a through hole is opened on the side of the tank body for the water distribution pipe to pass through, so that the water distribution pipe can extend from the side of the tank body and stay above the annular guide slope. Compared with extending the water distribution pipe into the top or bottom of the tank body, inserting the water distribution pipe into the side helps to flatten the water distribution tank, reduce the footprint of the water distribution tank, and can also effectively avoid the occurrence of water leakage caused by opening holes in the bottom.

[0036] like Figure 1As shown, a water distributor for anaerobic reaction equipment includes a water distribution tank and a spray unit, the water distribution tank includes a tank body 1, an annular guide slope 2 is arranged in the tank body 1, the annular guide slope 2 gradually slopes downward from the outer edge to the inner edge, and a recovery port 3 is arranged in the center of the annular guide slope 2; the spray unit includes a spray structure, and the spray structure is arranged as a whole above the annular guide slope 2, the spray structure includes a water outlet pipe 4 and a water distribution nozzle 5 connected to the water outlet pipe 4, and the water distribution nozzle 5 is provided with a water spray port opening toward the annular guide slope 2.

[0037] The water distribution tank of the present application includes a tank body 1 in which an annular guide slope 2 and a spray structure above the annular guide slope 2 are provided. The spray structure can spray water to the annular guide slope 2 through the water spray port on the water distribution nozzle 5, so that the sludge on the annular guide slope 2 is fully mixed with the water. The sludge on the annular guide slope 2 is vertically displaced under the action of its own gravity, and is displaced in a direction parallel to the tangent of the annular guide slope 2 under the impact of the water flow sprayed by the water distribution nozzle 5, that is, the sludge on the annular guide slope 2 is spirally moved toward the recovery port 3 under the combined action of the vertical force and the lateral force, so that the sludge and water are fully mixed, and the sludge can slide down to the recovery port 3 under the action of its own weight, thereby avoiding the sludge from being hidden in the tank body 1, and eliminating the operation of cleaning the sludge in the water distribution tank after the water distribution work is completed, thereby effectively reducing the occurrence of acidification caused by the sludge hiding for too long in the water distribution tank.

[0038] As a preferred implementation of the present application, Figure 1 As shown, the spray structure includes a plurality of water outlet pipes 4, which are distributed on the same horizontal plane and located at the same height as the tank body 1. The number of water outlet pipes 4 is set to be multiple, which increases the spraying area of ​​the spray structure, so that the sludge on the annular guide slope 2 can be more evenly spread, so as to be fully mixed with water, and reduce the occurrence of insufficient reaction caused by the inability of sludge to contact water, which helps to improve the water distribution efficiency of the water distribution tank, thereby improving the reaction efficiency of the anaerobic reactor; and the plurality of water outlet pipes 4 are distributed on the same horizontal plane, so that the vertical heights of the water outlets are consistent, and the different heights of the water outlet pipes are avoided, so as to avoid the water flow sprayed from the water outlet located above being blocked by the water outlet pipe located below, thereby improving the uniformity and consistency of the water spray.

[0039] As a preferred embodiment of this implementation, Figure 1As shown, each of the water outlet pipes 4 is connected to two of the water distribution nozzles 5. Each water outlet pipe 4 is connected to two water distribution nozzles 5, which increases the number of water distribution nozzles 5 above the annular guide slope 2, making the watering more uniform, and the sludge on the annular guide slope 2 can be more fully mixed with water, providing a guarantee for the subsequent reaction work of the anaerobic reaction equipment. This embodiment does not limit the number of water distribution nozzles 5 on each water outlet pipe 4, and it can also be one or more than two.

[0040] As another preferred embodiment of this embodiment, Figure 1 As shown, the projections of at least some of the multiple water-distributing nozzles 5 on the horizontal plane fall on a circle coaxial with the annular guide slope 2. The sludge can be moved in the same direction, that is, the tangent direction of the concentric circle, under the spreading action of the water-distributing nozzles 5, which reduces the occurrence of the phenomenon of mutual collision of the sludge under the action of the water-distributing nozzles 5 located at different positions, thereby ensuring the consistency of the sludge movement direction and helping to improve the water distribution efficiency of the water-distributing tank. Preferably, the water-distributing nozzles 5 whose projections on the horizontal plane are located in the same concentric circle have the same height in the vertical direction, and each water-distributing nozzle 5 whose projections on the horizontal plane are located in the same concentric circle has the same height difference with the annular guide slope 2 below, so that the impact force of the water flow sprayed by each water-distributing nozzle 5 on the sludge is the same, further improving the consistency of the movement direction of the sludge after being impacted by the water flow.

[0041] As a preferred example under this embodiment, Figure 1 As shown, the distance between any two adjacent water-distributing nozzles 5 projected on a circle coaxial with the annular guide slope 2 is equal, so that the water-distributing nozzles 5 can spread the water flow of the sludge more evenly, so that the sludge and the water flow can be fully mixed.

[0042] As a preferred embodiment of the application, the spray unit includes a rotating member, and the rotating member controls the water distribution nozzle 5 to rotate in a direction parallel to the guide slope. By providing a rotating member and driving the water distribution nozzle 5 to rotate in a direction parallel to the guide slope, the water flow sprayed by the water distribution nozzle 5 is made more uniform, and the annular guide slope 2 can be covered to the greatest extent, which greatly improves the mixing uniformity of the water flow and the sludge located above the annular guide slope 2.

[0043] As a preferred implementation of the application, Figure 1 As shown, it also includes a water distribution bag 6 for supplying water to the water outlet pipe 4, and the water distribution bag 6 is connected to the spray structure through a water distribution pipe 7. By providing the water distribution bag 6 for supplying water to the spray structure, the integrity of the water distributor is enhanced.

[0044] As another preferred embodiment of this embodiment, Figure 1 As shown, the water distribution bag 6 is located at the side of the tank body 1, and the side wall of the tank body 1 is provided with a through hole for the water distribution pipe 7 to pass through, and the water distribution pipe 7 passes through the tank body 1 in the horizontal direction through the through hole. By arranging the water distribution bag 6 at the side of the tank body 1 and opening a through hole for the water distribution pipe 7 to pass through the side of the tank body 1, the water distribution pipe 7 can extend from the side of the tank body 1 and stay above the annular guide slope 2. Compared with extending the water distribution pipe 7 at the top or bottom of the tank body 1, inserting the water distribution pipe 7 at the side helps to flatten the water distribution tank, reduce the floor space of the water distribution tank, and effectively avoid the occurrence of water leakage caused by opening a hole at the bottom.

[0045] The present application does not limit the connection method between the annular guide slope 2 and the water distribution tank, and it can adopt any one of the following embodiments:

[0046] Embodiment 1: The annular guide slope 2 is detachably connected to the tank body 1 by means of snap connection, plug connection, etc. The annular guide slope 2 and the tank body 1 are detachably connected, and the annular guide slope 2 with different inclination angles can be replaced according to different usage requirements, thereby improving the application adaptability of the water distribution tank.

[0047] Embodiment 2: The annular guide slope 2 is fixedly connected to the tank body 1 by welding or the like. The annular guide slope 2 is fixedly connected to the tank body 1 by welding or the like, and the annular guide slope 2 and the tank body 1 can be separately manufactured and then assembled, which reduces the difficulty of processing the tank body 1.

[0048] Embodiment 3: The annular guiding slope 2 is integrally formed with the tank body 1. Integral forming helps to improve the connection strength between the tank body 1 and the annular guiding slope 2.

[0049] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0050] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0051] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
