Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, and in particular to a high-efficiency anaerobic tower for wastewater treatment. Background Technology

[0002] An anaerobic tower is a treatment device that uses the degradation of organic matter in wastewater by anaerobic microorganisms under anaerobic conditions to purify the wastewater. Under anaerobic conditions, anaerobic bacteria in the wastewater decompose organic matter such as carbohydrates, proteins, and fats to produce organic acids. Then, under the action of methanogenic bacteria, these organic acids are further fermented to form methane, carbon dioxide, and hydrogen, thereby purifying the wastewater.

[0003] However, in existing anaerobic wastewater treatment towers, the wastewater inside the tower is difficult to mix thoroughly with the sludge, and it is easily clogged by the sludge. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency anaerobic tower for wastewater treatment. Through a multi-layer spiral structure, wastewater and sludge are fully mixed, thereby improving wastewater treatment efficiency. Furthermore, the multiple layers facilitate water distribution from top to bottom, reducing the clogging problem caused by direct start-up of the lower water distribution layer.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A high-efficiency anaerobic wastewater treatment tower includes an anaerobic tower body, within which a water distribution structure is provided. The water distribution structure comprises several vertically distributed water distribution layers, each containing an inlet, and several outlets connected to the inlets are also provided on the outer periphery.

[0007] The anaerobic tower body is connected to one or more water inlets, which are connected to the inlets of one or more water distribution layers. The outlet of the water distribution layer is connected to a guide pipe to guide the water outflow direction. Some or all of the water distribution layers are of the upward spiral type. The outlet end of the guide pipe of the upward spiral water distribution layer is inclined in a clockwise / counterclockwise direction to guide the water outflow in a spiral upward direction.

[0008] By adopting the above technical solution, the multi-layer water distribution layer structure is easy to process, and the guide pipe outlet on it makes the water flow out in a spiral upward shape, which can fully mix the outflowing sewage and sludge, thereby improving the sewage treatment efficiency of the reactor; the multi-layer water distribution layer is easy to start from top to bottom, reducing the problem of easy blockage caused by directly starting the lower water distribution layer.

[0009] Furthermore, the upper water distribution layers are of the upward spiral type, and the lower water distribution layers are of the downward spiral type. The outlet ends of the guide pipes of the downward spiral water distribution layers are all inclined downward in a clockwise / counterclockwise direction, guiding the water out in a spiral downward.

[0010] By adopting the above technical solution, the water outlet spiral descends from the lower water distribution layer, allowing the outflowing sewage to be fully mixed with the sludge at various locations at the bottom of the tower, thereby further improving the sewage treatment efficiency.

[0011] Furthermore, the upward-swirling water distribution layer is conical in shape, wider at the top and narrower at the bottom, with the water spiraling upwards along its outer perimeter while expanding outwards.

[0012] By adopting the above technical solution, the water outlet of the spiral water distribution layer can rise in a spiral manner and expand outward, which facilitates water distribution to the upper part of the entire anaerobic tower and reduces the space required for the water distribution structure.

[0013] Furthermore, the downward spiral water distribution layer is conical in shape, with a smaller top and a larger bottom. As the water spirals downward along its outer perimeter, it expands outward.

[0014] By adopting the above technical solution, the water outlet of the downward swirling water distribution layer can expand outward, making it easier to distribute water to the bottom of the anaerobic tower and reducing the space required for the water distribution structure.

[0015] Furthermore, the water distribution layers are set with the same external dimensions and are connected sequentially, one above the other.

[0016] By adopting the above technical solution, it is convenient to replace the water distribution layers with each other, select the number of water distribution layers as needed, facilitate processing and installation, and make adjustment easy.

[0017] Furthermore, vertical holes are opened at the top of the water distribution layer, and several horizontal holes are also opened inward around the outer periphery of the water distribution layer. The inner end of the horizontal holes is connected to the lower end of the vertical holes, and the water inlet is connected to the corresponding water inlet pipe, which is connected to the upper end of the corresponding vertical hole.

[0018] By adopting the above technical solution, the connection between the water inlet and different water outlet positions on the outer periphery of the water distribution layer is realized, and the water inlet pipe is connected to the water distribution layer from top to bottom, reducing the problem of blockage.

[0019] Furthermore, a receiving groove is provided at the lower part of the water distribution layer to accommodate the water inlet pipe in the adjacent water distribution layer below.

[0020] By adopting the above technical solution, it is convenient to connect and fix adjacent water distribution layers.

[0021] Furthermore, the inner end of the guide tube is threaded to the outer end of the horizontal hole.

[0022] By adopting the above technical solution, the installation and fixation of the guide tube were achieved.

[0023] Furthermore, the top of the water distribution structure is equipped with a top block, which is a cone shape with a pointed top.

[0024] By adopting the above technical solution, the problem of sludge accumulation at the top of the water distribution structure has been reduced.

[0025] In summary, the present invention has the following beneficial effects:

[0026] The multi-layer water distribution structure is easy to process. The guide pipe outlet on the top spiral water distribution layer makes the water flow out in a spiral upward shape, which can fully mix the outflowing sewage and sludge and improve the sewage treatment efficiency of the reactor. The multi-layer water distribution layer is easy to start from top to bottom, reducing the clogging problem caused by directly starting the lower water distribution layer.

[0027] The outlet ends of the guide pipes of the downward spiral water distribution layer are all inclined downward in a clockwise / counterclockwise direction, guiding the water outflow in a spiral downward, so that the outflowing sewage is fully mixed with the sludge at various positions at the bottom of the tower, further improving the sewage treatment efficiency.

[0028] The upper and lower swirling water distribution layers are conical, allowing the water from the upper and lower swirling water distribution layers to spiral upwards or downwards while also expanding outwards. This facilitates water distribution to the entire upper and lower parts of the anaerobic tower, reducing the space required for the water distribution structure. Attached Figure Description

[0033] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. These embodiments do not constitute a limitation of the present invention. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0034] A highly efficient anaerobic wastewater treatment tower, such as Figure 1As shown, the anaerobic tower body 1 includes a water distribution structure 2 fixed inside the anaerobic tower body 1. The anaerobic tower body 1 also contains existing structures such as a three-phase separator, a gas-water separator, and a biogas collection pipe, which will not be described in detail here. The water distribution structure 2 includes several water distribution layers 21 distributed vertically. Adjacent water distribution layers 21 and the bottom water distribution layer 21 and the anaerobic tower body 1 can be fixed to each other by means of snap-fit ​​or bolt connection. The water distribution layer 21 is provided with an inlet, and several outlets connected to the inlet are provided on the outer periphery to realize the outward distribution of water from the inlet to the various outlets on the outer periphery.

[0035] like Figure 1 and Figure 2 As shown, the anaerobic tower body 1 is connected to multiple water inlets, and the water inlets are fixedly connected to the corresponding water inlet pipes 3. A valve is installed at the outer end of the water inlet pipe 3 to control its opening and closing. The inner end of the water inlet pipe 3 is connected to the inlet of one or more water distribution layers 21. A guide pipe 22 is connected at the outlet of the outer periphery of the water distribution layer 21 to guide the water outflow direction.

[0036] The upper water distribution layers 21 are of the upward spiral type. The outlet ends of the guide pipes 22 of the upward spiral water distribution layers 21 are all inclined in the counterclockwise direction, guiding the water to rise in a spiral.

[0037] The lower water distribution layers 21 are of the downward spiral type. The outlet ends of the guide pipes 22 of the downward spiral water distribution layers 21 are all inclined downward in a counterclockwise direction, guiding the water out in a spiral downward.

[0038] The multi-layer water distribution layer 21 has a structure that is easy to manufacture. The guide pipe 22 outlet on the upper spiral water distribution layer 21 causes the water to rise in a spiral shape, which can fully mix the outflowing sewage with sludge and improve the sewage treatment efficiency of the reactor. The water outflow spiral descends from the lower water distribution layer 21, which can fully mix the outflowing sewage with sludge at various positions at the bottom of the tower, further improving the sewage treatment efficiency. The water distribution layer 21 is controlled by the valve on the inlet pipe 3 to start sequentially from top to bottom, reducing the easy blockage problem caused by directly starting the lower water distribution layer 21.

[0039] like Figure 1 As shown, the upward spiral water distribution layer 21 is conical, with a larger top and a smaller bottom. As the water spirals upward along its outer circumference, it expands outward, facilitating water distribution to the entire upper part of the anaerobic tower and reducing the space required for the water distribution structure 2.

[0040] The downward spiral water distribution layer 21 is conical in shape, with a smaller top and a larger bottom. As the water flows down spirally along its outer periphery, it expands outward, allowing the water from the downward spiral water distribution layer 21 to expand outward, facilitating water distribution to the bottom of the anaerobic tower and reducing the space required for the water distribution structure 2.

[0041] like Figure 1 and Figure 2As shown, the water distribution layers 21 are arranged with the same external dimensions, and are connected one above the other by bolts. This facilitates the replacement of the upper-swirling water distribution layer 21 or the lower-swirling water distribution layer 21, and allows the selection of the number of water distribution layers 21 as needed. This makes it easy to process and install, and also easy to adjust.

[0042] Specifically, a vertical hole is opened at the top center of the water distribution layer 21, and several horizontal holes are also opened inward around the outer periphery of the water distribution layer 21. The inner end of the horizontal hole is connected to the lower end of the vertical hole. The water inlet pipe 3 is fixed and connected to the upper end of the corresponding vertical hole. The water inlet pipe 3 is connected to the water distribution layer 21 from top to bottom, which reduces the problem of blockage.

[0043] The lower part of the water distribution layer 21 has a receiving groove and several weight reduction holes. The receiving groove accommodates the water inlet pipe 3 in the adjacent water distribution layer 21 below, which facilitates the connection and fixation between adjacent water distribution layers 21. The inner end of the guide pipe 22 is threaded to the outer end of the horizontal hole. The top of the water distribution structure 2 is also fixed with a top block 4. The top block 4 is a cone with a pointed top, which reduces the problem of sludge accumulation at the top of the water distribution structure 2.

[0044] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within the scope of its essence and protection. Such modifications or equivalent substitutions should also be considered to fall within the protection scope of the present invention.
