Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment equipment, and in particular to a gas collecting component, a gas collecting mechanism, a three-phase separator and an anaerobic reactor. Background Art

[0002] At present, anaerobic reactors used for sewage treatment are mainly divided into two categories: one is a low-load anaerobic filter and an anaerobic baffle reactor. This type of anaerobic reactor has a simple structure and does not contain a three-phase separator inside; the other is an anaerobic reactor with a three-phase separator. This type of anaerobic reactor has high sewage treatment efficiency and is therefore widely used in sewage treatment.

[0003] The working principle of the anaerobic reactor with a three-phase separator: the sewage is lifted to the bottom of the anaerobic reactor by a water pump, and the sewage is evenly distributed on the entire cross section by the water distribution system at the bottom. At the same time, the outlet pressure and gas production of the inlet water are used to make the wastewater fully contact and transfer mass with the high-concentration anaerobic sludge, degrading the organic matter in the wastewater to generate biogas. The biogas drives the wastewater to rise slowly in the reaction zone and contact with the anaerobic sludge to further degrade the organic matter. In the process of the simultaneous rise of biogas, water, and sludge, the biogas first enters the interior of the three-phase separator and is discharged through the pipeline. The sludge and wastewater rise to the separation zone through the gap of the three-phase separator. The sludge is precipitated and concentrated in the separation zone and refluxed to the lower part of the three-phase separator to maintain the biomass in the anaerobic reactor. The effluent after precipitation is discharged outside the tank through the pipeline.

[0004] In existing anaerobic reactors, three-phase separators such as Figure 1 As shown, it mainly includes a gas collecting mechanism, an air chamber and a fixing plate, and the three are connected together by welding to form a whole, which leads to a large volume of the three-phase separator, which is extremely inconvenient to install and transport, and very difficult to maintain.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0057] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0058] In existing anaerobic reactors, three-phase separators such as Figure 1 As shown, it mainly includes a gas collecting mechanism, an air chamber and a fixing plate, and the three are connected together by welding to form a whole, which leads to a large volume of the three-phase separator, which is extremely inconvenient to install and transport, and very difficult to maintain.

[0059] In order to solve the above technical problems, an embodiment of the present invention provides a gas collecting component, in which the first overlapping portion and the second overlapping portion on the first component and the second component of the gas collecting component can overlap the gas collecting components, so that the gas collecting channel can be formed without welding. In addition, the gas collecting component can make the three-phase separator modular, convenient for installation and transportation, and very simple for maintenance.

[0060] First refer to Figure 2-3An embodiment of the present invention provides an air collecting component 10, which includes a first component 11 and a second component 12, wherein the first side end of the first component 11 and the first side end of the second component 12 are connected to each other to form a V-shaped structure, which is conducive to air collection and the sedimentation of water and sludge. In addition, the first component 11 has a first overlapping portion 111 extending below its outer contour, and the second component 12 has a second overlapping portion 121 extending below its outer contour, and the first overlapping portion 111 and the second overlapping portion 121 can also form a V-shaped structure. In addition, in the embodiment provided by the present invention, there is no special restriction on the length of the first overlapping portion 111 and the second overlapping portion 121. For example Figure 2 In the embodiment, the length of the first overlapping portion 111 is significantly shorter than the length of the remaining portion of the first member 11, and the length of the second overlapping portion 121 is significantly shorter than the length of the remaining portion of the second member 12; for example Figure 3 In the embodiment, the length of the first overlapping portion 111 is greater than the length of the remaining portion of the first component 11 , and the length of the second overlapping portion 121 is also greater than the length of the remaining portion of the second component 12 .

[0061] In the embodiment provided by the present invention, the first component 11 and the second component 12 can both be plate-shaped, and their materials can be non-metallic materials and metal materials, such as PP, PE, PVC, 304 stainless steel, etc. In the manufacturing process, the molten material is injected into the mold for one-time molding to obtain the gas collecting component 10. The size of the first component 11 and the second component 12 can be designed according to the treatment volume of sewage and the requirements of the corresponding equipment (shell of the anaerobic reactor).

[0062] In the sewage treatment process, since water and sludge will fall on the outer surfaces of the first component 11 and the second component 12, in order to make the V-shaped structure of the gas collecting component 10 more stable, refer to Figure 3 As shown, in a possible implementation, the second side end of the first member 11 extends downward in the vertical direction to form a first vertical portion 112, and the second side end of the second member 12 extends downward in the vertical direction to form a second vertical portion 122, and the first vertical portion 112 and the second vertical portion 122 are arranged relative to each other, so that the gas collecting component 10 is not easily deformed by external force, which indirectly improves the strength of the gas collecting component 10 and further maintains its stable V-shaped structure. In addition, the arrangement of the first vertical portion 112 and the second vertical portion 122 can also facilitate subsequent installation.

[0063] Further, based on the above possible implementation scheme, continue to refer to Figure 4 As shown, the first vertical portion 112 and the second vertical portion 122 are connected by reinforcing ribs, which can further ensure the strength of the gas collecting component 10.

[0064] In another possible embodiment, the gas collecting component 10 further includes a reinforcing plate 14. Figure 5 As shown, the first component 11 and the second component 12 pass through the reinforcing plate, which can also further ensure the strength of the air collecting component 10.

[0065] As mentioned above, the V-shaped structure of the gas collecting component 10 is conducive to gas collection and the sedimentation of water and sludge. Specifically, in the process of water and sludge falling, they will fall on the outer surfaces of the first component 11 and the second component 12, and the inclined surfaces thereof can make the water and sludge automatically rise and fall. In order to enable the water and sludge that fall on the surfaces of the first component 11 and the second component 12 to rise and fall quickly therefrom, in a possible implementation scheme, the V-shaped top angle of the V-shaped structure is 60-90°. In addition, the V-shaped top angle of the V-shaped structure is within the above range, and its assembly in the anaerobic reactor can reduce the number of gas collecting components 10, thereby achieving the purpose of reducing costs.

[0066] Exemplarily, the V-shaped top angle of the V-shaped structure can be, but is not limited to, 60°, 61°, 62°, 63°, 64°, 65°, 66°, 67°, 68°, 69°, 70°, 71°, 72°, 73°, 74°, 75°, 76°, 77°, 78°, 79°, 80°, 81°, 82°, 83°, 84°, 85°, 86°, 87°, 88°, 89°, or 90°.

[0067] In addition, refer to Figure 6-7 An embodiment of the present invention further provides an air collecting mechanism, which includes two air collecting components 10, wherein one end of one adjacent air collecting component 10 is respectively abutted against a first overlapping portion 111 and a second overlapping portion 121 on the other air collecting component 10 to form an overlap, and an air blocking portion 41 is provided at the other end of one air collecting component 10.

[0068] Specifically, the number of gas collecting components 10 in the gas collecting mechanism 40 needs to be selected according to the cross-sectional area of ​​the anaerobic reactor. In a specific embodiment, the gas collecting mechanism 40 may include three gas collecting components 10, and adjacent gas collecting components 10 may overlap to form a gas collecting hood, and a gas blocking portion 41 is provided at one end of the first gas collecting component, that is, the gas blocking portion 41 can block the biogas from flowing out of the end, and can only flow out from the other end along the inner surface of the gas collecting hood.

For details, refer to Figure 7 (a). In addition, refer to Figure 7 (b) Even if the overlap is tilted, there may still be leakage.

[0071] Continue to refer to Figure 8 The frame 20 is made of a plurality of profiles or is formed by injection molding to form a cage-type frame, wherein the profile can be steel or the like. As described above, a plurality of frames 20 are stacked to form a layered structure, which is not only easy to assemble, but also allows for partial replacement. In addition, the frames of each layer and the adjacent layers are connected by conventional connection methods such as buckles and hooks. Moreover, the gas collecting mechanism 40 and the frame 20 can also be installed by buckles, hooks, tying, etc.

[0072] Reference Figure 8 In order to prevent gas leakage at the overlap of the gas collecting component 10 in the gas collecting mechanism 40, in a possible implementation, the gas collecting mechanism 40 is tilted, so that there is no gas storage and gas pressure at the overlap of the gas collecting component 10, so that no gas leakage occurs. The tilt angle of the gas collecting mechanism 40 is 0-45°.

[0073] Exemplarily, the inclination angle of the air collecting mechanism 40 can be, but is not limited to, 0°, 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, 45°.

[0079] Reference Fig.11 As shown, in a possible implementation scheme, in order to increase the area of ​​the separation zone (the separation zone refers to the area covered by the gas collecting mechanism, which can realize the function of three-phase separation) to reduce the area of ​​the gas chamber, the gas collecting mechanism 40 is symmetrically installed on both sides of the gas chamber 30.

[0080] Reference Fig.12 As shown, in a possible implementation, the three-phase separator is installed in the shell of the anaerobic reactor, and when the span is relatively large, in order to eliminate the impact of different sedimentation heights caused by different positions, the bottom of the shell of the anaerobic reactor is tilted and has the same inclination angle as the gas collecting mechanism 40 in the three-phase reactor.

[0081] Reference Fig.13As shown, in the gas, water and sludge mixing area, the gas, water and sludge are fully in contact, and under the action of the gas, the water and sludge are driven into the separation area. In the separation area, the gas enters the gas collecting mechanism 40, and the water and sludge rise along the surface of the gas collecting component 10.
