Description

Technical Field

[0001] The invention belongs to the technical field of pollution-clearing devices, and in particular relates to a pollution-blocking device for a sewage inspection well. Background Art

[0002] The drainage network is an important facility for conveying sewage and discharging rainwater. It maintains urban environmental sanitation and public health, including effectively preventing urban waterlogging, protecting urban water environment and water quality, improving the overall urban environmental quality and promoting sustainable urban development. Therefore, the normal operation of the urban drainage network plays a vital role in the healthy development of the city.

[0003] In order to reasonably operate, maintain and control the urban drainage network, it is necessary to understand the specific drainage conditions inside the network, including water volume, water quality, temperature and pH value. However, the operation of the drainage network is complicated, and there are many kinds of garbage floating in the pipes. Among them, flexible film garbage represented by plastic bags has the greatest impact on sewage pipe monitoring equipment. It is very easy to attach or hang on the measuring probe, which ultimately affects the measurement effect. The flexible film covers the flow velocity probe, resulting in a flow velocity measurement value of 0. Covering the water quality probe causes the probe to be at a fixed value for a long time and unable to reflect water quality changes. In more serious cases, the probe will be physically damaged due to excessive water flow resistance.

[0004] However, the traditional screen pollution interception technology has the problem of too much resistance. If the sewage pipe is not cleaned in time, it may cause siltation, blockage and even sewage overflow. It cannot be put into the traditional inspection well. It can only be carried out by expanding the screen room at key nodes such as pumping stations and using automatic mechanical slag removal. It is not suitable for conventional water power and water quality probe pre-placement pollution interception.

[0005] Therefore, how to prevent pollutants from hanging or adhering to the measuring equipment, facilitate cleaning, and not cause a significant impact on the hydrodynamic conditions of the sewage pipe has become a technical problem that needs to be solved urgently. Summary of the invention

[0006] In view of the above-mentioned shortcomings of the prior art, the object of the present invention is to provide a low-resistance plastic film floating object interception device for a sewage inspection well, which is intended to collect and remove plastic film floating garbage in the inspection well without affecting the hydrodynamic conditions of the sewage pipe.

[0007] In a first aspect, the present invention provides a sewage inspection well device, the device being arranged on a sewage water guide channel under the inspection well, comprising: a preset number of spokes, a spoke fixing belt, and a hanging component;

[0008] The spokes are fixedly arranged on the spoke fixing belt to intercept floating garbage;

[0009] The spoke fixing belt is an arc-shaped structure, used to provide support for the spokes;

[0010] The suspension component is fixedly connected to the spoke fixing belt and comprises a first cable, a mounting indicating spring and a second cable, and is used for suspending and moving the dirt-trapping device.

[0011] In an implementation of the first aspect, the spoke includes a top horizontal extension section, an inclined section, and a bottom horizontal extension section; wherein the top horizontal extension section, the inclined section, and the bottom horizontal extension section are rigid structures, and the transition portions of the top horizontal extension section, the inclined section, and the bottom horizontal extension section are flexible structures.

[0012] In an implementation of the first aspect, a counterweight is provided at the front end of the bottom horizontal extension section of the spoke, and the heights of the spoke in the sewage are different due to the counterweights of different weights to meet the garbage collection requirements at different water levels.

[0013] In an implementation of the first aspect, a preset number of pointed protrusions are provided at the bottom of the inclined section of the spoke and the bottom of the bottom horizontal extension section.

[0014] In an implementation of the first aspect, the pointed protrusion is of unidirectional design, and the head of the pointed protrusion is arranged toward the direction of water flow.

[0015] In an implementation of the first aspect, the spokes include a central spoke, a wing spoke, and a side spoke;

[0016] The central spoke is arranged at the center axis position of the spoke fixing belt;

[0017] The side spokes are symmetrically arranged with the central spoke as the axis;

[0018] The side spoke strips are arranged on the inspection well chamber and are connected to the two ends of the spoke fixing belt.

[0019] In an implementation of the first aspect, the orientations of the wing spokes are arranged to converge toward the orientation of the central spoke.

[0020] In an implementation of the first aspect, the mounting indication spring is disposed between the first cable and the second cable, and the amount of mounted garbage is estimated based on the elastic extension of the spring to achieve timely cleaning.

[0021] In an implementation of the first aspect, the curvature of the spoke fixing belt is an adjustable structure to accommodate inspection wells of different diameters.

[0022] In an implementation of the first aspect, a surface of the spoke fixing belt is coated with an anti-corrosion coating.

[0023] As described above, the garbage intercepting device of the present invention has a high efficiency in garbage interception and collection capability: through the structural design of the spokes, the dynamics of the water flow and the floating characteristics of the garbage are fully considered, and the rigid structure and the flat structure of the flexible transition part are combined to ensure the stability and durability of the spokes when intercepting garbage, and the necessary flexibility and impact resistance are provided through the flexible transition part. The spokes can effectively adapt to the changes in the water flow in the sewage water channel and the requirements of garbage interception while maintaining the integrity of the structure and the continuity of the function. In addition, by limiting the movement of the spokes in a vertical plane, the design also ensures that the spokes will not affect each other, thereby optimizing the overall performance of the garbage intercepting device. The present invention uses the combined effect of the rigid strips and the flexible transition strips. When the more plastic films are attached to the rigid strips, the greater the tension they are subjected to, and the strips will be closer to the water surface, reducing the overall water resistance. At the same time, the rigid strips at the edges will also be subjected to the radial tension generated by the impact of the water flow on the plastic film, and will move closer to the pipe wall, reducing the overall water resistance. Prevent excessive impact on the flow state of the sewage pipe. The garbage intercepting device described in the present invention can adapt to different water level conditions: by designing counterweights of different weights, the height of the spokes in the sewage can be accurately controlled. The counterweights ensure that the garbage intercepting device can maintain optimal garbage intercepting performance under various conditions, thereby protecting the unobstructed flow of the sewer system and reducing environmental pollution.

[0033] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0034] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0035] Trash interceptors are generally installed in the city's underground pipe system, especially under the inspection wells of sewage pipes. These inspection wells are the entrances for maintenance and repair of underground pipes. For example, in small village sewage treatment facilities: in their primary treatment stage, they are used to intercept and remove floating garbage in sewage entering the treatment plant to protect subsequent treatment equipment from being blocked or damaged; or in sewage discharge systems, especially those that merge with rainwater systems, they are used to intercept floating plastic film garbage brought in by rainwater flow.

[0036] The device is placed directly in the sewage gutter, which is the main channel for sewage flow. The device is used to intercept film floating garbage in sewage. The space of the inspection well and sewage gutter is usually small, so the design of the device needs to take this into account so that it can be effectively installed and operated in a limited space. The water flow in the installation environment has a certain flow rate and flow rate. The design of the device needs to be able to adapt to these water flow dynamics to ensure the effective interception of garbage without causing too much obstruction to the water flow. Considering that the installation environment of the device needs to take into account the safety of the staff, certain requirements are put forward for the installation safety and operability of the device.

[0037] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0038] like Figures 1 to 4 As shown, in one embodiment, the sewage intercepting device of the present invention is arranged on the sewage water channel under the inspection well, and comprises: a preset number of spokes 11, a spoke fixing belt 12, and a hanging component 13;

[0039] The spokes 11 are fixedly arranged on the spoke fixing belt 12 to intercept floating garbage;

[0040] The spoke fixing belt 12 is an arc-shaped structure, used to provide support for the spoke 11; its specific gravity is less than that of water, and it has a certain buoyancy when submerged, and has the ability to bend downward. When the pipe is fully submerged, it can fit the pipe wall or the upper surface of the inspection well to reduce the fluid resistance when submerged;

[0041] The suspension component 13 is fixedly connected to the spoke fixing belt 12, and includes a first cable 131, a mounting indicating spring 132, and a second cable 133, and is used for suspending and moving the dirt-trapping device.

[0042] Furthermore, the spokes include a top horizontal extension section 21, an inclined section 22, and a bottom horizontal extension section 23; wherein the top horizontal extension section 21, the inclined section 22, and the bottom horizontal extension section 23 are rigid structures, and the transition portions of the top horizontal extension section 21, the inclined section 22, and the bottom horizontal extension section 23 are flexible structures.

[0043] The top horizontal extension is oriented parallel to the main flow direction of the water. This section is rigid, meaning it will not bend or deform under normal use. Its straight orientation and rigid structure are used to provide a stable platform, ensuring that the trash can be effectively captured and intercepted plastic film trash floating on the water surface.

[0044] The inclined section starts from the end of the top horizontal extension section, gradually turns from a horizontal position to a vertical position, and its direction gradually changes from parallel to the water flow direction to perpendicular to the water flow direction. It guides the garbage from the top horizontal extension section to the bottom horizontal extension section; the rigid structure is also adopted, and this design helps to reduce the impact of the water flow on the garbage and maintain the stability of the shape and position, thereby improving the interception efficiency.

[0045] The horizontal extension at the bottom, pointing in the main flow direction, is also a rigid structure. This part of the spoke is located below the inclined section and is used to intercept trash at a lower water level while maintaining the shape and function of the spoke.

[0046] The transition part adopts a flexible structure. This design allows the spokes to bend between the vertical planes to a certain extent, so that they can buffer and adapt when subjected to external forces (such as water flow impact, garbage impact, etc.); at the same time, it limits the left and right swing of the spokes on the horizontal plane and reduces the collision damage between the spokes. The main function of the flexible transition part is to connect the top horizontal extension section, the inclined section and the bottom horizontal extension section of the rigid structure. In one embodiment, the vertical force analysis front view when the flow velocity is 0 is as follows Figure 2b As shown in the figure, the vertical force analysis front view when the flow velocity is large is as follows Figure 2cThe top view of the horizontal force analysis when the flow velocity is 0 is shown in 2d, and the top view of the horizontal force analysis when the flow velocity is large is shown in Figure 2e As shown. It can be seen that when the spokes are impacted by large flow, the design takes into account the principles of fluid dynamics to improve the durability and reliability of the spokes and reduce the impact on the flow pattern of the pipeline. Specifically, when sewage passes through the sewage guide channel at a large flow rate, the impact force of the water flow will affect the spokes. This impact force may cause additional stress on the spokes, which may cause structural damage or reduce its interception efficiency if the spokes are not designed properly. In terms of design, the spokes have a certain degree of flexibility under the impact of the fluid. This means that when the spokes are impacted, the spokes can extend vertically, thereby reducing the stress concentration caused by the impact of water flow or garbage impact. This ductility of the spokes can adaptively adjust their shape to reduce the flow resistance area, allowing the water flow to pass more smoothly, thereby reducing the impact on the flow pattern of the pipeline. Due to the flexible design of the spokes, they can disperse stress when they are impacted and avoid stress concentration at a specific point, thereby improving the overall durability and reliability of the spokes. Furthermore, because the spokes can adjust their shapes adaptively, they can reduce the flow resistance, allowing the water flow to maintain its original flow state when passing through, thereby reducing the impact on the flow state of the entire sewage channel. This design helps to maintain the stable operation of the sewage system and avoid the negative consequences caused by the impact of the sewage interception device on the water flow, such as a decrease in water flow speed and accumulation of sediment in the water body.

[0047] The flat structure makes the layout and movement trajectory of the spokes simpler, making it easier for maintenance personnel to inspect, clean and replace them. The non-staggered design between the spokes reduces the potential risk of getting stuck or damaged, and improves the operating safety of the device.

[0048] The flat spoke design, which combines a rigid structure with a flexible transition section, ensures the stability and durability of the spokes when intercepting garbage, while providing the necessary flexibility and impact resistance through the flexible transition section. This design enables the spokes to effectively adapt to the changes in water flow and garbage interception requirements in the sewage channel while maintaining the integrity of the structure and the continuity of its functions. By limiting the movement of the spokes in one plane, the design also ensures that the spokes do not affect each other, thereby optimizing the overall performance of the interceptor.

[0049] Furthermore, a counterweight block 24 is provided at the front end of the bottom horizontal extension section of the spoke. The counterweight blocks 24 with different weights make the heights of the spokes in the sewage different to meet the garbage collection requirements at different water levels.

[0050] The counterweight block allows the immersion depth of the spokes in the sewage to be adjusted by adding extra weight. Under normal conditions, in order to further fit the pipe groove and match the characteristics of the pipe groove flow rate being small in the middle and large on both sides, a counterweight rule of heavy in the middle and light on both sides can be adopted. At the same time, the height of the spokes in the water can be adjusted by changing the weight of the counterweight block according to different water depths. When the downstream monitoring device is located at the bottom of the pipe, a heavier counterweight block can be used to make the spokes sink to a lower level in order to intercept garbage close to the bottom of the water. When the downstream monitoring device is located in the middle and top of the pipe, a lighter counterweight block can be used to keep the spokes in a higher position in order to intercept garbage floating on the water surface or at a higher water level.

[0051] The counterweights are designed to be replaceable or adjustable so that fluctuations in water levels can be quickly responded to without having to replace the entire spoke or unit. By adjusting the counterweights, the spokes can adapt to seasonal water level changes, maintaining the effectiveness of the interceptor. Replacing or adjusting the counterweights is relatively simple and does not require complex tools or expertise, reducing maintenance costs and difficulties. Properly adjusting the height of the spokes can more effectively intercept trash and reduce the likelihood of trash passing through, thereby improving the overall efficiency of the interceptor.

[0052] like Figure 3 As shown, the inclined section 22 of the spoke and the bottom 23 of the horizontal extension section are provided with a preset number of pointed protrusions 31. The pointed protrusions 31 are unidirectionally designed, and the heads of the pointed protrusions are arranged facing the direction of the water flow.

[0053] Specifically, the pointed protrusion 31 is located at the inclined section 22 and the bottom 23 of the horizontal extension section of the spoke, that is, at the part where the spoke contacts or is close to the water surface. The shape of the pointed protrusion is similar to a hook, with a sharp head structure. The head of the pointed protrusion is arranged to face the main flow direction of the water flow.

[0054] The hook-shaped pointed protrusions can effectively hook and intercept garbage floating on the water surface, especially those lightweight and flexible garbage that may move quickly with the water flow. Due to the hook shape of the pointed protrusions, they can prevent the intercepted garbage from sliding back down or being washed away by the water flow. The arrangement of the pointed protrusions in the direction of the water flow helps to guide the garbage to move along the spokes and eventually be collected by the spokes. The hook-shaped protrusions increase the contact area and friction between the spokes and the garbage, thereby improving the interception efficiency. The one-way design of the pointed protrusions ensures that once the garbage is intercepted, it is difficult to escape against the direction of the water flow, which improves the interception efficiency of the entire garbage interception device. Due to the hook-shaped structure of the pointed protrusions, it is relatively easy to clean up the intercepted garbage, and the garbage can be removed from the protrusions by simple mechanical or manual operations. The number and arrangement of the pointed protrusions can be preset according to actual needs to adapt to different water flow speeds and garbage types.

[0055] Further, such as Figure 4 As shown, the spokes include a central spoke 41, wing spokes 42 and side spokes 43; the central spoke 41 is arranged at the central axis of the spoke fixing belt 12; the wing spokes 42 are arranged symmetrically with the central spoke 41 as an axis; the side spokes 43 are placed on the inspection well chamber and connected to the two ends of the spoke fixing belt 12. The direction of the wing spokes 43 is set to converge in the direction of the central spoke. The wing spokes 43 are installed on both sides, one side is made of metal and has a larger mass, and one side is made of plastic and has a smaller mass. When the pollution intercepting device is placed in the well, the wing spokes 43 with a larger mass face downwards, which is convenient for hoisting and placement.

[0056] Specifically, the central spoke is located at the center axis of the spoke fixing belt, which is on the center line of the entire trash intercepting device. It is responsible for intercepting garbage floating along the center line of the water flow. The wing spokes are symmetrically arranged with the central spoke as the axis. They are located on both sides of the central spoke and are equidistant from the central spoke. The function of the wing spokes is to expand the interception range and capture garbage that deviates from the center line of the water flow but is still in the mainstream area. Their symmetrical design helps to maintain the balance of the device while improving the interception efficiency. The side spokes are arranged on the inspection well chamber and are connected to the two ends of the spoke fixing belt. They are located at the edge of the trash intercepting device, close to the wall of the well chamber. The side spokes are used to intercept garbage close to the edge of the well chamber, which may deviate from the mainstream due to the edge effect of the water flow. The presence of the side spokes ensures that the interception range of the entire trash intercepting device covers the outermost area of ​​the water flow.

[0057] The spokes are designed to converge toward the central spoke, forming an interception network with the central spoke as the convergence point. The converging orientation makes the ends of the wing spokes face the central spoke, which can concentrate on intercepting garbage flowing to the central area. When the water flow pushes the garbage to the center, the wing spokes can effectively guide it to the central spoke, thereby improving the interception efficiency. By converging the orientation of the wing spokes, the chance of garbage escaping during the interception process can be reduced. Garbage is more easily intercepted when it approaches the central area because it faces the joint interception of multiple spokes. Converging orientation helps to guide the water flow in the direction of the spokes, which can reduce the impact of the water flow on the garbage, making it easier for the garbage to be intercepted rather than washed away by the water flow. When the spokes converge, they support each other structurally, which enhances the stability of the entire garbage interceptor, enabling it to better resist the impact of the water flow and the impact of garbage. Converging orientation can better adapt to different sizes of garbage and flow in the case of variable flow. The central spoke acts as the main interception point to handle larger or heavier garbage, while the wing spokes assist in intercepting smaller or lighter garbage. In short, the converging pointing design of the spokes is to improve the interception efficiency of the pollution-blocking device, reduce garbage escape, optimize the water flow path, enhance structural stability, and facilitate maintenance and garbage collection, thereby making the pollution-blocking device more effective and reliable.

[0058] By combining the central spoke, wing spokes and edge spokes, the interceptor can form a comprehensive interception network, covering the entire area from the center of the water flow to the edge, thereby maximizing the garbage interception effect. This spoke layout not only improves the interception efficiency, but also enhances the structural stability of the entire device, because the central spoke serves as a supporting axis, and the wing spokes and edge spokes on both sides provide balanced support. Spokes in different positions can be adjusted according to the actual water flow conditions and garbage distribution to meet different interception needs. This spoke design ensures that the interceptor can operate efficiently and stably through reasonable layout and function allocation, and adapts to garbage interception needs in various sewage environments.

[0059] As shown in FIG. 2 , the mounting indication spring 132 is disposed between the first cable 131 and the second cable 133 , and the amount of mounted garbage is estimated based on the elastic extension of the spring to achieve timely cleaning.

[0060] Specifically, the mounting indicator spring is set and used to monitor the amount of garbage accumulated on the garbage intercepting device, and is located between the first cable and the second cable. The two cables are used to suspend and move the garbage intercepting device. The setting position of the spring enables it to sense the change in fluid resistance to the garbage on the device. When garbage accumulates on the garbage intercepting device, the resistance to the device increases. This increased resistance causes the mounting indicator spring to elastically stretch. The degree of elongation of the spring is proportional to the amount of accumulated garbage. By observing the elongation of the spring, the amount of garbage hanging on the garbage intercepting device can be estimated. This estimation is usually based on the elastic coefficient of the spring and the relationship between the pre-set elongation and the weight of the garbage.

[0061] By monitoring the elongation of the spring, it is possible to understand the accumulation of garbage in a timely manner, so that when the amount of garbage reaches a certain threshold, it can be cleaned up to avoid excessive accumulation that affects the efficiency and function of the garbage interceptor. The load indicator spring helps prevent the garbage interceptor from being damaged by garbage overload. Cleaning before the spring reaches its maximum elongation limit can protect the device from excessive stress. The elongation data of the spring can be used to develop a maintenance plan for the garbage interceptor, for example, to arrange the frequency of cleaning and maintenance according to the speed and amount of garbage accumulation.

[0062] In summary, the loading indicator spring is a simple and effective feedback mechanism that makes the operation and maintenance of the trash interceptor more intelligent and efficient. By monitoring the elastic extension of the spring, the amount of garbage accumulation can be estimated in real time, thereby ensuring the continued normal operation of the trash interceptor and extending its service life.

[0063] Furthermore, the spoke fixing belt 12 is divided into two half arcs, which are connected to the cable part by a hinge. The half arc can be folded down by the hinge and has a certain horizontal support strength. The arc is an adjustable structure to adapt to inspection well chambers of different diameters. The surface of the spoke fixing belt is coated with an anti-corrosion coating.

[0064] The adjustable curvature design allows the spoke fixing belt to adapt to inspection wells of different diameters. This is because the diameter of the inspection well may vary depending on the engineering standard, location or age. This structure is usually achieved by adjusting the curvature of the spoke fixing belt. This involves movable connection points, retractable components or adjustable fastening devices, so that the fixing belt can be adjusted according to the specific size of the inspection well. The adjustable curvature improves the adaptability of the spoke fixing belt, allowing it to be widely used in inspection wells of different sizes without the need to customize specific components for each inspection well.

[0065] The adjustable arc structure enables the spoke fixing belt to not only adapt to inspection wells of different diameters, but also maintain its performance and durability in harsh sewage environments. This design improves the flexibility and reliability of the pollution-blocking device, enabling it to operate effectively in a variety of environments.

[0066] By combining the central spokes, flank spokes and edge spokes, the present invention enables the garbage interception device to form a comprehensive interception network, covering the entire area from the center of the water flow to the edge, thereby maximizing the garbage interception effect. This spoke layout not only improves the interception efficiency, but also enhances the structural stability of the entire device, because the central spoke serves as a support axis, and the flank spokes and edge spokes on both sides provide balanced support. Spokes in different positions can be adjusted according to the actual water flow conditions and garbage distribution to meet different interception requirements. This spoke design ensures that the garbage interception device can operate efficiently and stably through reasonable layout and function allocation, and adapt to garbage interception needs in various sewage environments.

[0067] The adjustable curvature structure allows the spoke fixing belt to adapt to different diameters of manholes. This is because the diameter of the manhole may vary depending on the engineering standard, location or age. The adjustable curvature design allows the spoke fixing belt to flexibly adjust its curvature to adapt to manholes of different sizes according to the specific application environment and needs. This design improves the applicability and flexibility of the waste interceptor, allowing it to be widely used in a variety of engineering environments without the need to customize specific components for each specific application scenario.

[0068] In one embodiment, if Figure 5 As shown, the installation steps of the pollution intercepting device of the present invention are as follows:

[0069] S1. Place the sewage intercepting device in the sewage channel under the inspection well. First, ensure that the first cable 131 is firmly fixed on the device; then put another cable 51 on the lighter side spoke 43, which is to balance the gravity when placing the device and facilitate the adjustment of the spatial structure of the device.

[0070] S2. Slowly lower the device to a position slightly higher than the platform of the inspection well chamber through the first cable 131. Due to the center of gravity of the flank spokes 43, the lighter side will face downward, reducing the width of the overall structure so that it can pass through the inspection well shaft. By shaking the first cable 131 left and right, the position of the heavier side can be adjusted so that it is placed on the platform on one side of the inspection well chamber. Then, by pulling the other cable 51, gradually open the fixing belt 12 on the other side until the entire device is placed in place. Finally, loosen and retract the other cable 51, and fix the second cable 133 to the hook of the inspection well anti-fall net to ensure the stability of the device.

[0071] S3. Check the spring of the device regularly to monitor the accumulation of garbage. If the length of the spring reaches a preset threshold, it means that enough garbage has accumulated on the device and needs to be cleaned. By pulling the second cable 133, the device can be pulled up so that its spring is folded, making it easier to pull out from the inspection well.

[0072] S4. After clearing the mounted garbage, repeat step S1 to place the device.

[0073] In summary, the low-resistance plastic film floating debris intercepting device for sewage inspection wells provided by the present invention can not only efficiently intercept floating garbage, but also adapt to different environmental conditions and maintain long-term stable operation by combining the reasonable layout of the central spokes, wing spokes and side spokes, and adopting the design of adjustable arc structure and anti-corrosion coating. These design features enable the intercepting device to play an effective role in urban sewage treatment, rainwater drainage systems and other occasions where garbage interception is required, protect the normal operation of subsequent treatment facilities, reduce maintenance costs, and improve the treatment efficiency of the overall system.

[0074] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
