Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, and in particular to a water distributor that relies on hydraulic power to rotate. Background Technology

[0002] The upflow anaerobic sludge blanket (UASB) reactor, as a core piece of equipment in high-efficiency anaerobic treatment processes, directly impacts wastewater treatment efficiency through the performance of its water distribution system. An ideal water distribution system must meet three main requirements: uniform water distribution, effective hydraulic mixing, and low maintenance. Existing technologies suffer from the following shortcomings:

[0003] (1) Mechanically driven water distributor: requires an additional motor or transmission mechanism, which not only increases energy consumption (accounting for about 15% to 20% of the total energy consumption of the reactor), but is also prone to failure in a humid anaerobic environment, resulting in high maintenance costs.

[0004] (2) Fixed water distributor: such as double-layer perforated pipe structure, there is a water distribution blind zone (CV value is often >10%), which leads to excessive local sludge load or insufficient reaction. Utility Model Content

[0005] The purpose of this invention is to provide a water distributor that relies on hydraulic power to rotate, so as to solve one or more technical problems existing in the prior art, or at least provide a beneficial option or create conditions.

[0006] The technical solution adopted to solve the above-mentioned technical problems is as follows:

[0007] This utility model provides a water distributor that is driven by hydraulic power to rotate, including a water distributor body, a main inlet pipe and multiple water distribution pipes. The water distributor body has multiple concentrically arranged annular tracks, and several inclined guide vanes are provided between two adjacent annular tracks. A rotating shaft is rotatably provided in the middle of the water distributor body, and the rotating shaft is provided with an elastic scraper. The multiple water distribution pipes extend along the radial direction of the water distributor body and are all distributed on the water inlet side of the water distributor body. The two ends of each water distribution pipe are a closed end and a connected end, respectively. The connected ends of the multiple water pipes are all connected to the main inlet pipe. Each water distribution pipe is provided with multiple oblique water distribution holes, and the multiple oblique water distribution holes are all in contact with the elastic scraper.

[0008] The beneficial effects of this utility model are:

[0009] Wastewater flows through the main inlet pipe to the distribution pipe, and then exits obliquely through the radial distribution pipe. The high-pressure water inlet creates a vortex flow, which drives the guide vanes and elastic scrapers to rotate. The elastic scrapers are made of soft rubber and can scrape away sludge clogging the oblique distribution holes, preventing blockage. This application utilizes hydrodynamic rotation to improve uniformity and reduce clogging.

[0011] As a further improvement to the above technical solution, the angle between the guide vane and the axis of the water distributor body is 30-45°.

[0012] As a further improvement to the above technical solution, the rotating shaft is rotatably located in the middle of the water distributor body via a sealed bearing.

[0013] As a further improvement to the above technical solution, the water distributor body is made of stainless steel.

[0014] As a further improvement to the above technical solution, the rotating shaft is a hollow component, and the main water inlet pipe passes through the inside of the rotating shaft.

[0015] As a further improvement to the above technical solution, the multiple water distribution pipes are distributed in a tree-like pattern.

[0016] As a further improvement to the above technical solution, the water distributor also includes a reactor, the water distributor body is located inside the reactor, and the multiple water distribution pipes are matched with the inner diameter of the reactor.

[0017] As a further improvement to the above technical solution, a wear-resistant slider is provided at one end of the rotating shaft near the water distributor body, and the wear-resistant slider slides in contact with the annular track.

[0018] As a further improvement to the above technical solution, the wear-resistant slider is a ceramic component. Attached Figure Description

[0028] Reference Figures 1 to 4 This utility model provides a water distributor that relies on hydraulic power to drive rotation, and the following embodiments are provided:

[0029] A water distributor driven by hydraulic power includes a water distributor body 100, a main inlet pipe 200, and multiple water distribution pipes 210. The water distributor body 100 is provided with two concentric annular tracks 110, and several inclined guide vanes 120 are provided between two adjacent annular tracks 110. The guide vanes 120 form an angle of 30-45° with the axis of the water distributor body 100, converting axial water flow into tangential kinetic energy. The rotating water flow drives the water distributor to rotate, further improving the uniformity of water distribution.

[0030] Multiple water distribution pipes 210 extend radially along the water distributor body 100. Each water distribution pipe 210 has a closed end and a connected end, respectively. The connected ends of all pipes are connected to the main inlet pipe 200. Each water distribution pipe 210 has multiple oblique water distribution holes 211, allowing high-pressure, oblique water to flow out, which helps to create a vortex flow and drives the rotation of the guide vanes 120 and the elastic scraper 140. The axis of the oblique water distribution holes 211 forms an angle of 15-20° with the radial direction of the water distributor body 100, creating a reaction torque. The oblique water distribution holes 211 are gradually expanding, with a spacing of 100mm between them. They use Φ8 / 12mm gradually expanding holes, and the number of holes is calculated based on the flow rate, with each hole designed for a flow rate of 0.5–1 m³ / h. The multiple water distribution pipes 210 are evenly distributed on the inlet side of the water distributor body 100. (Refer to...) Figure 2 Multiple water distribution pipes 210 are distributed in a tree-like pattern.

[0031] A rotating shaft 130 is rotatably mounted in the middle of the water distributor body 100. The rotating shaft 130 is equipped with elastic scrapers 140, and multiple oblique water distribution holes 211 are engaged with the elastic scrapers 140. As the water flow rotates, the elastic scrapers 140 rotate accordingly, engaging with different oblique water distribution holes 211 during rotation, thus removing sludge and preventing blockages. Wastewater flows through the main inlet pipe 200 to the distribution pipe 210, and then exits obliquely through the radial distribution pipe 210. The high-pressure water inlet creates a vortex flow, driving the guide vanes 120 and the elastic scrapers 140 to rotate. The elastic scrapers 140 are made of soft rubber and can scrape away sludge clogging the oblique water distribution holes 211, preventing blockages. This application utilizes hydrodynamic rotation to improve uniformity and reduce clogging.

[0032] Furthermore, the rotating shaft 130 is rotatably mounted in the middle of the water distributor body 100 via a mechanically sealed bearing 212. This mechanically sealed bearing 212 uses a nitrile rubber seal ring, which can effectively withstand system pressure and prevent leakage. By placing the bearing in the middle, a strong intermediate support point is provided for the rotating shaft 130. Working in conjunction with the bottom support system, this design greatly improves the rotational stability of the entire rotating system under high-speed water flow impact, effectively suppressing radial runout and vibration, thereby extending the service life of the equipment under long-term continuous operation.

[0033] The water distributor body 100 is made of a single stainless steel component, such as 304 or 316L stainless steel, with a thickness of 5mm. This material selection not only gives the water distributor extremely high structural strength and rigidity, enabling it to withstand the enormous torque and weight of the water distribution pipe 210 and the water flow, but its excellent corrosion resistance also ensures long-term stable operation of the entire system in environments with corrosive media, such as sewage treatment and chemical processing, fundamentally avoiding secondary pollution and structural damage to the equipment caused by rust.

[0034] The rotating shaft 130 is designed as a hollow component, forming a water passage inside. The stationary external main water inlet pipe 200 passes directly through the hollow rotating shaft 130. This flow channel design greatly simplifies the water supply pipeline structure, achieving the most direct and efficient water flow transfer between the static water supply system and the dynamic rotating water distribution system. The water flow does not need to pass through any complex hoses or external rotating joints, but is directly delivered from the center of the main shaft to the rotating water distributor body 100, significantly reducing potential leakage risks and maintenance complexity.

[0035] The water distributor system also includes the reactor 300 to which it is applied, with the distributor body 100 located at the center of the reactor 300. Its multiple radial water distribution pipes 210 are arranged in a dendritic, symmetrical pattern, with their total length precisely matching the inner diameter of the reactor 300. This design ensures that the spray holes at the ends of the water distribution pipes 210 can cover as far as the vicinity of the reactor 300 wall, thereby achieving uniform water distribution across the entire cross-section of the reactor 300 without dead zones. This completely avoids the formation of blind spots in water distribution, providing uniform hydraulic load and nutrients to the packing material or microorganisms within the reactor 300, thus directly improving the overall treatment efficiency and effectiveness of the reactor 300.

[0036] To further optimize the wear resistance and lifespan of the bottom support, a fixed annular track 110 is provided at the center of the bottom of the reactor 300. This track is made of ultra-high molecular weight polyethylene, which has an extremely low coefficient of friction and self-lubricating properties. Correspondingly, a wear-resistant slider is fixedly installed at one end of the rotating shaft 130 near the water distributor body 100. This wear-resistant slider is preferably a high-performance ceramic component, such as alumina or silicon carbide ceramic.

[0037] The bottom of the wear-resistant slider is machined with a sliding surface that matches the annular track 110. When the rotating shaft 130 rotates under the drive of water flow, the ceramic wear-resistant slider rotates with the shaft, and its sliding surface undergoes relative sliding friction with the fixed ultra-high molecular weight polyethylene annular track 110. The extremely high hardness, wear resistance, and corrosion resistance of the ceramic material, combined with the extremely low coefficient of friction of the polymer track, ensures that the entire rotating system can operate smoothly with minimal resistance even in sludge environments rich in abrasive particles. This key improvement minimizes wear on the bottom support components, extends the maintenance cycle from the traditional months to several years, and significantly reduces the total life-cycle maintenance cost of the equipment, making it particularly suitable for industrial-scale continuous operation scenarios with extremely high requirements for reliability and economy.

[0038] This application also has the following beneficial effects:

[0039] (1) Energy saving: Energy consumption is reduced by 15% to 20% compared with mechanical drive. It is driven by water power and requires no additional power, thus reducing operating costs.

[0040] (2) Uniformity: Dynamic rotation enables water distribution coverage angle to reach 360°, CV value to drop below 5%, and sludge-sewage contact area to increase by 40%;

[0041] (3) Reliability: The non-contact flow guide design reduces wear by 90%, and the self-cleaning system extends the clogging cycle to more than 6 months;

[0042] (4) Adaptability: It can rotate stably within a flow range of 3 to 20 m3 / h and adapt to UASB load fluctuations.

[0043] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
