Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of garbage treatment equipment, and particularly to a conveying pipeline and an anaerobic reactor having the same. Background Art
[0002] The leachate produced by garbage incineration and landfill projects has poor water quality and is discharged or reused after being treated by a leachate treatment system. Anaerobic reaction is required for leachate treatment to degrade organic matter. If the anaerobic reaction conditions are not met, the normal-temperature leachate in the anaerobic reactor will be heated and kept at a temperature close to 40 °C. In the related art, due to the increase in leachate temperature, the solubility of CaCO3 decreases, and scale is more likely to form in the pipeline in the anaerobic effluent section. Therefore, after the effluent pipeline of the anaerobic reactor operates for a period of time, the effluent pipeline is severely blocked by scale, affecting the normal drainage of the effluent pipeline, and thus regular maintenance or even pipeline replacement is required, resulting in an increase in maintenance costs, so the practicability is poor. Summary of the Utility Model

Therefore, the practicability of the conveying pipeline of the embodiment of the utility model is improved.
[0007] Thus, the conveying pipeline of the embodiment of the utility model is not prone to scale formation and has the advantage of high practicability.

[0022] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.
[0023] The conveying pipeline 100 according to an embodiment of the present invention will be described below with reference to the drawings.
[0024] As Figure 1 shown, the conveying pipeline 100 of the embodiment of the present utility model includes: a pipe body 1 and a flow guiding member 2.
[0025] The pipe body 1 is adapted to be connected to the drainage port 201 of the anaerobic reactor 200. That is to say, one end of the pipe body 1 communicates with the drainage port 201 of the anaerobic reactor 200, and the other end of the pipe body 1 communicates with the outside, so that the leachate is discharged through the pipe body 1. The flow guiding member 2 is arranged on the inner wall surface of the pipe body 1, and the flow guiding member 2 is spiral along the extending direction of the pipe body 1.
[0026] When the leachate passes through the pipe body 1, a part of the leachate far from the inner wall surface of the pipe body 1 flows along the extending direction of the pipe body 1, and a part of the leachate close to the inner wall surface of the pipe body 1 is guided by the flow guiding member 2, and the flowing direction of the leachate is generally consistent with the extending direction of the flow guiding member 2. The flow guiding member 2 is spiral along the extending direction of the pipe body 1. That is to say, the flow guiding member 2 forms a certain angle with the extending direction of the pipe body 1, so that the flow path of a part of the leachate close to the inner wall surface of the pipe body 1 is longer than that of a part of the leachate far from the inner wall surface of the pipe body 1. Since the flow rate of the leachate entering the pipe body 1 is constant during drainage, the flow velocity of a part of the leachate close to the inner wall surface of the pipe body 1 is greater than that of a part of the leachate far from the inner wall surface of the pipe body 1. Therefore, scale is not likely to form on the inner wall surface of the pipe body 1.
[0027] By arranging the spiral flow guiding member 2 on the inner wall surface of the pipe body 1 of the conveying pipeline 100 of the embodiment of the present utility model, the flow velocity of the leachate close to the inner wall surface of the pipe body 1 is increased, so that scale is not likely to form on the inner wall surface of the pipe body 1, and the problem that the pipeline for discharging leachate in the related art needs to be frequently repaired or replaced is solved. Therefore, the practicability of the conveying pipeline 100 of the embodiment of the present utility model is improved.
[0028] Thus, scale is not likely to form in the conveying pipeline 100 of the embodiment of the present utility model, and it has the advantage of high practicability.
[0029] In some embodiments, there are multiple flow guiding members 2, and the multiple flow guiding members 2 are all arranged on the inner wall surface of the pipe body 1, and the multiple flow guiding members 2 are spaced apart in the circumferential direction of the pipe body 1. In other words, the multiple flow guiding members 2 are evenly distributed in the pipe body 1, so that the leachate close to the inner wall surface of the pipe body 1 can be evenly guided by the flow guiding members 2, and scale is not likely to form on the inner wall surface of the pipe body 1.
[0030] In some embodiments, the pipe body 1 includes a first section 11 and a second section 12, the first section 11 and the second section 12 are communicated, the extending direction of the first section 11 is perpendicular to the extending direction of the second section 12, and the first section 11 is adapted to be connected to the drainage port 201 of the anaerobic reactor 200.
[0031] It is understandable that the drain outlet 201 of the anaerobic reactor 200 is at a relatively high height. The first section 11 is connected to the drain outlet 201 of the anaerobic reactor 200, and the second section 12 is arranged downward so as to be connected to other devices, thereby improving the adaptability of the conveying pipeline 100 of the embodiment of the present utility model.
[0032] In some embodiments, the flow guide member 2 is arranged in the second section 12, and the dimension of the flow guide member 2 in the extending direction of the second section 12 is the same as the dimension of the second section 12 in its extending direction. Thus, the second section 12 is not easily fouled.
[0033] In some embodiments, the cross-sectional area of each flow guide member 2 decreases in the direction close to the central axis of the pipe body 1 on the inner wall surface of the pipe body 1. Thus, the resistance of the flow guide member 2 to the leachate is reduced, enabling the leachate to flow more smoothly in the pipe body 1.
[0034] Optionally, the ratio of the dimension of the flow guide member 2 in the radial direction of the pipe body 1 to the diameter dimension of the pipe body 1 is 0.02 - 0.06. Optionally, the ratio of the dimension of the flow guide member 2 in the radial direction of the pipe body 1 to the diameter dimension of the pipe body 1 is 0.03 - 0.05. Thus, it is ensured that the flow guide member 2 can have a guiding effect on the leachate close to the inner wall surface of the pipe body 1, avoiding the structure of the inner wall surface of the pipe body 1, and preventing the flow guide member 2 from having too large a size, causing structural redundancy, and ensuring the smooth flow of the leachate in the pipe body 1.
[0035] Among them, the ratio of the dimension of the flow guide member 2 in the radial direction of the pipe body 1 to the diameter dimension of the pipe body 1 includes but is not limited to 0.02, 0.03, 0.04, 0.05 or 0.06.
[0036] Optionally, the ratio of the wall thickness of the pipe body 1 to the diameter dimension of the pipe body 1 is 0.05 - 0.12. Optionally, the ratio of the wall thickness of the pipe body 1 to the diameter dimension of the pipe body 1 is 0.06 - 0.1. Optionally, the ratio of the wall thickness of the pipe body 1 to the diameter dimension of the pipe body 1 is 0.07 - 0.09. Thus, it is ensured that the pipe body 1 has sufficient structural strength.
[0037] Among them, the ratio of the wall thickness of the pipe body 1 to the diameter dimension of the pipe body 1 includes but is not limited to 0.05, 0.06, 0.07, 0.08, 0.09, 0.1, 0.11 or 0.12.
[0038] In some embodiments, the pipe body 1 is one of a plastic pipe and a rubber pipe, thereby improving the corrosion resistance of the pipe body 1 and extending the service life of the conveying pipeline 100 of the embodiment of the present utility model.

Therefore, the practicability of the conveying pipeline 100 of the embodiment of the present utility model is improved.
