Description

Technical Field

[0001] The present invention relates to the technical field of anaerobic treatment equipment, and specifically to an anaerobic water distribution device. Background Art

[0002] An anaerobic tank is a highly efficient multi-stage internal circulation anaerobic reactor, which has the characteristics of less land occupation, high organic loading, stronger shock resistance, more stable performance, and simpler operation and management. Currently, anaerobic tanks are widely used in the treatment of high-concentration organic wastewater, such as corn starch wastewater, citric acid wastewater, beer wastewater, potato processing wastewater, and alcohol wastewater. For an anaerobic tank, the key to its efficient operation lies in the internal water distribution device.

[0003] In the prior art, the widely used water distribution methods in anaerobic tanks are swirl water distribution and multi-point water distribution. Due to the uniformity problem of the distribution points and the inability of the water between the distribution points to mix, the multi-point water distribution results in uneven water distribution. Although the traditional swirl water distribution is superior to the multi-point water distribution method, during the water distribution process, due to the flow velocity of the water forming a swirl, the water at the center and the outside of the swirl plate cannot be fully mixed. In summary, neither of these two water distribution devices can maximize the requirement of uniform water distribution of the water distribution device. Summary of the Invention

[0004] The purpose of the present invention is to provide an anaerobic water distribution device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] An anaerobic water distribution device includes a main water distribution pipeline. One side of the main water distribution pipeline is provided with a first swirl plate, and the first swirl plate is of a conical structure. The main water distribution pipeline is connected to at least one inlet water distribution pipeline, and the inlet water distribution pipeline is located above the first swirl plate. At least one swirl stirrer is fixedly connected to the outside of the first swirl plate, and the swirl stirrers are arranged around the axis of the first swirl plate.

[0007] As a further solution of the present invention: There are three inlet water distribution pipelines, and the outlets of the three inlet water distribution pipelines are circumferentially arranged above the first swirl plate.

[0008] As a further solution of the present invention: The swirl stirring includes a first swirl stirrer arranged above the first swirl plate and a second swirl stirrer arranged on the periphery of the first swirl plate.

[0009] As a further solution of the present invention: Both the first swirl stirrer and the second swirl stirrer are provided with a plurality of them and are circumferentially arranged around the axis of the first swirl plate.

[0010] As a further solution of the present invention: the first swirl stirrer and the second swirl stirrer are at the same height.

[0011] As a further solution of the present invention: the first swirl stirrer and the second swirl stirrer have the same structure. The first swirl stirrer and the second swirl stirrer are both formed by buckling the backs of two second swirl plates, and swirl channels are arranged circumferentially on the second swirl plates.

[0012] As a further solution of the present invention: a baffle is arranged below the first swirl plate, and the first swirl plate is fixedly connected to the baffle through a first bracket.

[0013] As a further solution of the present invention: a water inlet is provided between the upper end of the baffle and the outer edge of the first swirl plate.

[0014] As a further solution of the present invention: a bottom plate is arranged below the baffle, and the baffle is fixedly connected to the bottom plate through a second bracket.

[0015] As a further solution of the present invention: the first swirl plate, the baffle, and the bottom plate are all steel plates.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The present invention can solve the common problems existing in swirl water distribution by performing water distribution. By using two-stage swirl water distribution, the water at the center and the outside of the swirl plate is fully mixed, so as to distribute water evenly.

[0018] 2. The present invention utilizes the conical structure of the conical swirl plate itself to make the inlet water tangent to it, and forms a clockwise or counterclockwise swirl according to the setting direction of the inlet water pipe, reducing the equipment cost while performing swirl water distribution.

[0019] 3. The present invention is provided with a small water flow stirrer. By using the principle that the linear velocity of the outer circle tangent is faster than that of the inner circle, the stirrer is rotated, so as to form multiple small swirl regions, thereby further mixing the external and internal water to supplement the problem of uneven water distribution existing in the whole swirl water distribution.

Specific implementation manner

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-3 , in the embodiment of the present invention, an anaerobic water distribution device includes a main water distribution pipe 1. A first cyclone plate 3 is arranged on one side of the main water distribution pipe 1. The first cyclone plate 3 is of a conical structure. The main water distribution pipe 1 is connected with at least one inlet water distribution pipe 2. The inlet water distribution pipe 2 is located above the first cyclone plate 3. In this embodiment, there are three inlet water distribution pipes 2. The water outlets of the three inlet water distribution pipes 2 are circumferentially arranged above the first cyclone plate 3. The three inlet water distribution pipes 2 inlet water in the same tangential direction. On the inner wall of the first cyclone plate 3, cyclone water distribution is formed through the first cyclone plate 3.

[0026] At least one cyclone stirrer is fixedly connected to the outside of the first cyclone plate 3. The cyclone stirrers are arranged around the axis of the first cyclone plate 3. The cyclone stirring includes a first cyclone stirrer 4 arranged above the first cyclone plate 3 and a second cyclone stirrer 5 arranged outside the first cyclone plate 3. There are multiple first cyclone stirrers 4 and second cyclone stirrers 5 and they are circumferentially arranged around the axis of the first cyclone plate 3. The first cyclone stirrer 4 and the second cyclone stirrer 5 are at the same height. The first cyclone stirrer 4 and the second cyclone stirrer 5 have the same structure. The first cyclone stirrer 4 and the second cyclone stirrer 5 are both formed by buckling the backs of two second cyclone plates 11. The second cyclone plate 11 is circumferentially provided with cyclone flow channels 12. One end close to the center of the circle is closed and the other end is open. Water flows in from the open end, driving the small cyclone plate to rotate, thus forming a small-scale cyclone. In addition, the materials of the first cyclone stirrer 4 and the second cyclone stirrer 5 are ABS materials.

[0027] A baffle 6 is arranged below the first cyclone plate 3. The first cyclone plate 3 is fixedly connected to the baffle 6 through a first support 8. There is a water inlet 10 between the upper end of the baffle 6 and the outer edge of the first cyclone plate 3. Water flows out of the anaerobic water distribution device from here. A bottom plate 7 is arranged below the baffle 6. The baffle 6 is fixedly connected to the bottom plate 7 through a second support 9. The first cyclone plate 3, the baffle 6, and the bottom plate 7 are all made of steel plates. The anaerobic water distribution device of the present application is installed in an anaerobic tank.

[0028] When the present invention is in use, sewage is distributed through the main water distribution pipe 1, and the water is evenly dispersed into a plurality of inlet water distribution pipes 2. It enters the anaerobic water distribution device through the inlet water distribution pipes 2. The inlet water forms a clockwise or counterclockwise swirling flow when tangent to the first swirl plate 3, forming a large swirl water distribution, so that the inlet water is fully agitated; the fully agitated and evenly distributed inlet water flows into the anaerobic tank through the water inlet between the first swirl plate 3 and the baffle 6; at this time, the first swirl stirrer 4 and the second swirl stirrer 5 arranged on the inner layer and the outer layer outside the anaerobic water distribution device are also working. Since the linear velocity of the outer circle tangent is faster than that of the inner circle, through the push of the water flow, the first swirl stirrer 4 and the second swirl stirrer 5 are rotated, so as to form a plurality of small swirl regions inside the anaerobic tank, and perform dead-angle-free agitation to supplement the problem of uneven water distribution existing in the whole swirl water distribution, so that the inlet water is fully agitated and evenly distributed.
