Description

Technical Field

[0001] This utility model belongs to the field of solid-liquid separation technology, specifically relating to a spiral tube packing material with simple structure, high sedimentation efficiency, strong adaptability, and good sludge removal effect, and a sedimentation tank with the spiral tube packing material installed vertically. Background Technology

[0002] Sedimentation is one of the most commonly used solid-liquid separation technologies. Based on the principle of shallow sedimentation, the sedimentation efficiency of a sedimentation tank is mainly determined by the sedimentation area. Therefore, adding inclined plates or tubes to the sedimentation tank can greatly increase the sedimentation area, thereby improving sedimentation efficiency. Currently, inclined plates or tubes in sedimentation tanks are generally straight components, requiring installation at a 60° angle. Due to the angle after installation, some areas of the sedimentation tank have gaps in the inclined plates or tubes, rendering these areas ineffective for sedimentation and hindering efficiency improvement. Furthermore, because inclined plates or tubes need to be installed at an angle, they are mainly installed in rectangular or square sedimentation tanks, making them difficult to install in circular or irregularly shaped tanks, thus limiting their application.

[0003] In existing technologies, to address the insufficient number of inclined plates or tubes in sedimentation tanks, one approach is to reduce the surface load, i.e., decrease the ratio of unit flow rate to sedimentation tank area, thereby extending the residence time of turbid water in the sedimentation tank and providing more time for particle settling, thus allowing more particles sufficient time to settle to the bottom. However, reducing the surface load leads to a decrease in sedimentation efficiency, necessitating an increase in sedimentation tank area and significantly increasing construction costs. Another approach is to add flocculants to the sedimentation tank to accelerate sedimentation by promoting the binding of suspended solids in the turbid water. However, continuous use of flocculants results in high chemical costs, and improper flocculant dosage control can affect subsequent treatment processes and pose potential hazards to the environment and operator health. Additionally, another approach involves staggered arrangement of multiple layers of inclined tubes or plates within the sedimentation tank to increase the sedimentation area and shorten the particle settling distance, thereby improving overall sedimentation efficiency. However, staggered multi-layered inclined tubes or plates are not only difficult to install, but also prone to clogging after a period of use due to their small spacing, increasing the difficulty and cost of cleaning and maintenance. In addition, longitudinal guide (or partition) walls can be installed in the sedimentation tank to make the water flow in the tank more stable, effectively avoiding unfavorable water flow phenomena such as short-circuiting, deflection, and density flow, thereby reducing the interference of water flow on particle sedimentation and improving sedimentation efficiency. However, since the design and construction of guide (or partition) walls require precise calculations and careful construction by professional technicians, unreasonable design or poor construction quality may aggravate water flow turbulence. Moreover, adding guide (or partition) walls will divide the sedimentation tank into multiple sedimentation chambers, thereby increasing the difficulty of cleaning sediment.

[0004] Therefore, researching a simple, efficient, adaptable, and effective sedimentation tank packing material and sedimentation tank is of great practical significance for improving the sedimentation efficiency of existing sedimentation tanks. Utility Model Content

[0005] In order to solve the problems mentioned in the background art, this utility model provides a spiral tube packing material with simple structure, high sedimentation efficiency, strong adaptability and good sludge discharge effect, and also provides a sedimentation tank with vertically installed spiral tube packing material.

[0006] The spiral wound tube packing of this utility model is implemented as follows: the spiral wound tube packing includes at least two pipes that are intertwined along the length direction, and a pipe clamp fixed to the outside of the intertwined pipes to stabilize the relative position of each pipe. When the spiral wound tube packing is placed vertically, the inner and outer walls of each pipe form a slope greater than 30° and less than 70° with the horizontal plane.

[0007] Furthermore, the pipe clamp is a square, rectangular, circular, or hexagonal sleeve, which is fixedly wrapped around both ends or the entire length of the pipe where the spiral filler is intertwined.

[0008] Furthermore, the pipes of the spiral packing are either spirally wound in a cross direction or spirally wound in the same direction.

[0009] The sedimentation tank with vertically installed spiral wound tube packing of this utility model is implemented as follows: it includes a tank body, an inlet pipe, and an outlet pipe. The inlet pipe is fixedly installed at the lower part of one side of the tank body, and the outlet pipe is fixedly installed at the upper part of the tank body on the side away from the inlet pipe. Several spiral wound tube packings are vertically installed in the tank body. The inner and outer walls of each pipe of the spiral wound tube packing in the tank body form a slope greater than 30° and less than 70° with the horizontal plane.

[0010] Furthermore, the outer walls of the clamps of adjacent spiral wound packing tubes in the pool abut against each other.

[0011] Furthermore, within the pool body, in the blank areas between each spiral tube packing and the pool wall, spiral tube packing with a small cross-sectional size is vertically fixed or filled with sealing filler. The spiral tube packing with a small cross-sectional size is made to reduce the number of pipes and / or reduce the pipe diameter.

[0012] Furthermore, the inlet pipe is fixedly installed below the spiral wound packing on one side of the pool body, and the outlet pipe is fixedly installed above the spiral wound packing on the side of the pool body away from the inlet pipe.

[0013] Furthermore, the pool body is provided with a conical sedimentation section below the water inlet pipe, and a drain pipe and a drain valve are provided at the bottom of the conical sedimentation section.

[0014] This utility model has the following beneficial effects:

[0015] 1. The spiral wound tube packing of this utility model is composed of intertwined and fixedly positioned pipes. Compared with traditional straight and inclined plate or pipe packing, it can effectively avoid the problem of ineffective sedimentation areas caused by installation inclination, and increase the effective sedimentation area. At the same time, the intertwined and fixedly positioned pipes create a slope on the inner and outer walls of the pipes, which can further increase the effective sedimentation area and ultimately achieve a revolutionary improvement in the utilization rate of sedimentation space. It also facilitates the discharge of sludge under its own weight, thereby greatly improving the sedimentation efficiency of the sedimentation tank and making it less prone to clogging.

[0016] 2. The spiral wound tube packing of this utility model is optimized and innovated through fluid dynamics. The spiral wound tube packing is set with mutually spirally wound pipes, so that the pipes form a continuous and gradually changing flow channel. This not only significantly reduces water flow disturbance compared with traditional straight inclined pipes, but also the micro vortex effect generated by the cross spiral of multiple pipes can promote particle collision and aggregation, thereby shortening the sedimentation time and further improving the sedimentation efficiency.

[0017] 3. The spiral wound tube packing of this utility model is designed to be applicable to sedimentation tanks of various shapes, such as rectangular, circular and irregular shapes, breaking through the limitation that traditional straight inclined plates or inclined tubes are mainly applicable to rectangular sedimentation tanks, and its adaptability is significantly enhanced.

[0018] 4. The sedimentation tank with vertically installed spiral wound tube packing of this utility model, by vertically arranging several modularly designed spiral wound tube packings in the tank, not only facilitates the quick disassembly and replacement of each spiral wound tube packing in the tank, but also realizes the serialization and standardization of spiral wound tube packings, thereby enabling the spiral wound tube packings to be mass-produced in the factory, which is conducive to reducing the use cost of spiral wound tube packings.

[0019] 5. This utility model features a sedimentation tank with vertically installed spiral wound tube packing. By optimizing the relative positions of the inlet pipe, outlet pipe, and spiral wound tube packing in the sedimentation tank, the pipes in the spiral wound tube packing can form a self-cleaning channel under the flushing of water flow, which can effectively improve the anti-clogging performance of the pipes. Combined with the conical sedimentation section design at the bottom of the tank and the sewage pipe and sewage valve, it can completely solve the problem of easy sludge accumulation in traditional multi-layer inclined pipes or inclined plates.

[0020] In summary, this utility model has the characteristics of simple structure, high sedimentation efficiency, strong adaptability, and good sludge removal effect. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this does not limit the present invention in any way. Any changes or improvements made based on the teachings of the present invention shall fall within the protection scope of the present invention.

[0031] like Figures 1 to 4 As shown, the spiral wound tube packing of this utility model includes at least two pipes 5 that are intertwined along the length direction, and a pipe clamp 6 fixed to the outside of the intertwined pipes 5 to stabilize the relative position of each pipe 5. When the spiral wound tube packing 4 is placed vertically, the inner and outer walls of each pipe 5 form a slope greater than 30° and less than 70° with the horizontal plane.

[0032] The pipe clamp 6 is a square, rectangular, circular or hexagonal sleeve, and the pipe clamp 6 is fixedly wrapped around both ends or the entire length of the pipe 5 where the spiral filler 4 is intertwined.

[0033] The pipes 5 of the spiral filler 4 are either spirally wound in a cross direction or spirally wound in the same direction.

[0034] like Figures 5 to 8As shown, the sedimentation tank of this utility model with vertically installed spiral wound tube packing includes a tank body 1, an inlet pipe 2, and an outlet pipe 3. The inlet pipe 2 is fixedly installed at the lower part of one side of the tank body 1, and the outlet pipe 3 is fixedly installed at the upper part of the tank body 1 away from the inlet pipe 2. Several spiral wound tube packings 4 are vertically installed inside the tank body 1. The inner and outer walls of each pipe 5 of the spiral wound tube packings 4 inside the tank body 1 form a slope greater than 30° and less than 70° with the horizontal plane.

[0035] The outer walls of the clamps 6 of adjacent spiral wound tube packing 4 inside the pool body 1 abut against each other, and the outer walls of the clamps 6 of the spiral wound tube packing 4 near the edge inside the pool body 1 abut against the pool wall of the pool body 1.

[0036] The pool body 1 is vertically fixed with spiral tube packing 4 with a small cross-sectional size in the blank area between each spiral tube packing 4 and the pool body 1 wall, or filled with sealing filler 7. The spiral tube packing 4 with a small cross-sectional size is made to reduce the number of pipes 5 and / or reduce the diameter of pipes 5.

[0037] The inlet pipe 2 is fixedly installed below the spiral wound packing 4 on one side of the pool body 1, and the outlet pipe 3 is fixedly installed above the spiral wound packing 4 on the side of the pool body 1 away from the inlet pipe 2.

[0041] During operation, turbid water enters the tank body 1 through the inlet pipe 2 below the spiral wound tube packing 4. The turbid water then flows upwards through the pipe 5 inside the spiral wound tube packing 4 or between the outer walls of the pipe 5. Suspended solids in the turbid water settle on the inner and outer walls of the pipe 5 and slide down the slope to the conical sedimentation section 8 under gravity. The supernatant is discharged through the outlet pipe 3 above the spiral wound tube packing 4.
