Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to an environmentally friendly wastewater recycling and reuse device based on water environment engineering. Background Technology

[0002] In the field of water environment engineering, wastewater recycling and reuse is a key link in achieving sustainable water resource utilization and reducing environmental pressure. Currently, a lot of environmental wastewater is discharged directly and indiscriminately without treatment, causing severe pollution in many rivers. This not only damages the original water quality of the rivers but also spreads pollution to many aquatic plants and garden vegetation, resulting in large-scale death of aquatic plants and garden vegetation. Existing environmental wastewater recycling equipment has low purification effect in actual treatment and is difficult to reduce the economic cost of water treatment, thus hindering its widespread adoption.

[0003] Current existing technologies, such as patent application number "CN202120337836.6" entitled "An Environmentally Friendly Wastewater Recycling and Reuse Equipment Based on Water Environment Engineering," include "a housing, the interior of which is provided with a treatment chamber for treating wastewater, the interior of which is provided with a stirring mechanism for agitating the wastewater, the upper end of which is provided with a sprayer for injecting flocculant into the treatment chamber, the bottom of which has an opening, the interior of which is provided with a filter plate, the bottom of which has a locking mechanism for fixing the filter plate, and the exterior of which is provided with..." The pump mechanism extracts the treated water. This invention allows flocculant to be added into the treatment chamber, and multiple stirring rods are driven by a motor to increase the efficiency of flocculant use. After filtration, the pressure plate can be lifted by pulling a block, and then the clamping plate and filter plate can be removed for further processing of the waste. However, wastewater treatment requires continuous operation around the clock to ensure timely treatment of the continuously flowing wastewater. The motor driving the stirring rods must operate continuously or at high frequency. As a high-energy-consuming device, the motor's long-term continuous operation consumes a large amount of electrical energy, increasing the energy burden and hindering energy conservation and consumption reduction. Utility Model Content

[0004] The purpose of this invention is to provide an environmentally friendly wastewater recycling and reuse device based on water environment engineering, which can fully mix sewage and flocculant without using a motor, effectively reducing energy consumption.

[0005] The aforementioned environmentally friendly wastewater recycling and reuse equipment based on water environment engineering includes a box body with an opening at the top. A sealing plate is installed at the opening, and a sprayer is mounted on the sealing plate. Two feed pipes pass through the sealing plate, one of which is connected to the sprayer. Above the filter plate of the box body, two spiral tubes with opposite directions of rotation are installed. The two spiral tubes are cross-connected and communicate with each other. An installation plate is installed between the spiral tubes and the filter plate, and two drain pipes pass through the installation plate. Both ends of the two spiral tubes are detachably connected to the feed pipe and the drain pipe, respectively.

[0006] Furthermore, both ends of the spiral tube are threadedly connected to the feed pipe and the drain pipe respectively via threaded sleeves.

[0007] Furthermore, the housing and the enclosure are connected by fasteners.

[0008] Furthermore, the sealing plate and the mounting plate are connected by two connecting plates.

[0009] Furthermore, fins are provided on the inner wall of the helical intersection of the two helical tubes.

[0010] Furthermore, the inner wall of the spiral tube is sandblasted.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This invention installs two spiral tubes with opposite directions of rotation and intersecting within a housing, connecting two feed pipes and two drain pipes. Flocculant and wastewater are injected into the two spiral tubes through the two feed pipes respectively. The flocculant and wastewater converge at the intersection of the two spiral tubes. After being divided and twisted, the liquid flows to the next intersection and converges again at the next intersection. This allows for thorough mixing of wastewater and flocculant without the use of a motor, effectively reducing energy consumption. Attached Figure Description

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0014] Example This embodiment describes an environmentally friendly wastewater recycling and reuse device based on water environment engineering, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes a housing 1 with an opening at the top. A sealing plate 8 is installed at the opening, and a sprayer 6 is mounted on the sealing plate 8. Two feed pipes 7 pass through the sealing plate 8, one of which is connected to the sprayer 6. Two spiral tubes 3 with opposite directions of rotation are installed above the filter plate 11 of the housing 1. The two spiral tubes 3 are connected and intersected. An installation plate 2 is installed between the spiral tubes 3 and the filter plate 11. Two drain pipes 10 pass through the installation plate 2. Both ends of the two spiral tubes 3 are detachably connected to the feed pipe 7 and the drain pipe 10, respectively. The opening of the box 1 is sealed by a sealing plate 8. The box 1 and the sealing plate 8 are connected by a buckle 5. The hook of the buckle is welded or threaded to the side wall of the sealing plate 8, and the buckle ring is welded or threaded to the side wall of the box 1. The sealing plate 8 is fixed to the opening of the box 1 by connecting the buckle ring and the buckle. There are at least two buckles, which are symmetrically distributed. A sprayer 6 is welded or threaded to the top of the sealing plate 8. There are two fixing holes on the sealing plate 8. A feed pipe 7 is welded or glued into each fixing hole. The discharge ends of the two feed pipes 7 pass through the fixing holes and are located below the sealing plate 8. One feed pipe 7 is connected to the sewage pipe, and the other feed pipe 7 is connected to the sprayer 6. The flocculant is discharged into the box 1 through the feed pipe 7 by the sprayer 6, and the wastewater in the sewage pipe is discharged into the box 1 through the feed pipe 7. The housing 1 contains two spiral tubes 3, which are spiral in opposite directions and connected at their intersection. A mounting plate 2 is located below each spiral tube 3, with two mounting holes. Drain pipes 10 are welded or glued into each mounting hole. The drain pipes 10 and feed pipes 7 are detachably connected to both ends of the spiral tubes 3. The two feed pipes 7 are inserted into the water inlets of the two spiral tubes 3; the two drain pipes 10 are inserted into the water outlets of the spiral tubes 3, thus connecting the water inlet of the spiral tube 3 to the feed pipes 7 and the water outlet of the spiral tube 3 to the drain pipes 10. Both ends of the spiral tube 3 are threadedly connected to the feed pipe 7 and the drain pipe 10 respectively via threaded sleeves 9. External threads are provided on the outer walls of both the inlet and outlet ends of the spiral tube 3. External threads are also provided on the outlet ends of the two feed pipes 7 and the inlet ends of the two drain pipes 10. The threaded sleeves 9 are threadedly connected to the inlet ends of the spiral tube 3 and the drain pipe 10 respectively, connecting the spiral tube 3 to the feed pipes 7. The threaded sleeves 9 are also threadedly connected to the outlet ends of the spiral tube 3 and the inlet ends of the drain pipes 10, connecting the spiral tube 3 to the drain pipes 10. The two spiral tubes 3 are easy to assemble and disassemble. In use, the flocculant is delivered to the feed pipe 7 through the sprayer 6 and then enters one of the spiral tubes 3. The other feed pipe 7 introduces the wastewater into the other spiral tube 3. The two spiral tubes 3 rotate in opposite directions and are intersecting, so that the flocculant and wastewater converge at the intersection. After they converge, they are split into two liquid streams again. The divided and twisted liquid streams are reassembled when they flow to the next intersection. This process is repeated in each intersection unit, thereby achieving extremely fast and uniform mixing of flocculant and wastewater. The two spiral tubes 3 rotate in opposite directions, and the fluid flows they generate also flow in opposite directions. This reverse rotation generates strong shear and torsional forces at the intersection point, causing the fluid to produce a three-dimensional, complex rotational motion. The spiral tubes 3 with opposite rotation directions can efficiently convert the axial kinetic energy of the fluid into lateral diffusion energy, generating strong secondary flows and vortices. The vortices can penetrate the laminar sublayer of the fluid, greatly promoting the contact frequency and efficiency between flocculant molecules and colloidal particles in wastewater at the microscale. No motor or stirring rod is needed; the mixing energy comes entirely from the pumping pressure energy of the fluid itself, greatly reducing the operating energy consumption of the equipment and meeting the requirements of energy conservation and environmental protection. The mixing energy of the spiral tubes 3 promotes rapid diffusion of the flocculant, causing the colloidal particles to gradually grow after destabilization, making it easier to form flocs with uniform size, dense structure, and excellent settling performance. The flocs formed after thorough mixing have excellent settling performance. Filtering them through the filter plate 11 results in a sludge concentration... Higher height and smaller size reduce energy consumption and reagent costs in the sludge dewatering process. The treated wastewater is then discharged from tank 1 via a pump connected to tank 1 for further wastewater treatment. Stable and efficient mixing can buffer fluctuations in influent water quality and quantity, providing a relatively stable condition for subsequent processes, thereby ensuring that indicators such as effluent turbidity and phosphorus content consistently meet discharge or reuse standards. Furthermore, the inner wall of the spiral tube 3 is sandblasted, creating an uneven surface that generates vortices when fluid flows through it. These vortices increase the turbulence of the water flow, increasing the contact probability between flocculant and wastewater, thus achieving rapid and uniform mixing. The turbulence and vortices generated on the sandblasted surface have a strong self-cleaning effect on the inner wall of the spiral tube 3, effectively preventing material deposition on the wall surface and maintaining the long-term unobstructed and stable operation of the spiral tube 3. Without consuming additional energy, it significantly improves the mixing speed, uniformity, and final flocculation effect. Furthermore, the spiral tube 3 can be lengthened or more intersection points can be added to accommodate different water volumes and required mixing intensities, making it more flexible in use. The spiral tube 3 is installed between the sealing plate 8 and the mounting plate 2 via the threaded sleeve 9. When the spiral tube 3 is damaged or blocked, it can be disassembled for cleaning or replacement, making it more flexible in use. like Figure 1 , Figure 2 and Figure 4 As shown, the sealing plate 8 and the mounting plate 2 are connected by two connecting plates 4; two connecting plates 4 are provided between the sealing plate 8 and the mounting plate 2, and they are connected by two mounting plates 2, which makes it easier to take the mounting plate 2 and the spiral tube 3 out of the box 1 or to put them into the box 1 after installation, which is more conducive to the installation and disassembly of the spiral tube 3. like Figure 2 As shown, fins 12 are provided on the inner wall of the spiral confluence of the two spiral tubes 3. The spiral tubes 3 themselves are responsible for generating large-scale rotation and confluence, while the fins 12 set in the confluence area are like a series of high-speed rotating blades, which act precisely at the moment of collision of the two fluids with opposite directions of rotation and the highest energy. This can maximize the conversion of the fluid's kinetic energy into shear force to tear and divide the flow streams, and the mixing efficiency is much higher than that of simple pipe wall confluence. The presence of fins 12 will generate a large number of smaller and stronger vortices in its wake. These micro vortices greatly increase the contact area between the fluids, achieving more thorough micro-mixing and ensuring that the flocculant has a higher probability of collision with every colloidal particle in the wastewater. Even at the spiral confluence, there may be laminar flow areas with uneven mixing. The fins 12 can mechanically cut into the fluid, forcibly exchanging the central fluid with the wall fluid and one fluid with another, ensuring that all fluids participate equally in the mixing process and achieving uniform mixing throughout the entire area. This can form flocs with more uniform size, denser structure, and better settling performance, directly improving the effect of subsequent sedimentation or filtration processes. In actual use, the housing 1 is equipped with two spiral tubes 3 with opposite directions of rotation and cross-connection. The opening at the top of the housing 1 is sealed by the sealing plate 8. The two spiral tubes 3 are connected to two feed pipes 7 and a drain pipe 10 respectively. The flocculant is injected into the feed pipe 7 through the sprayer 6 and then enters the spiral tube 3 connected to it. The other feed pipe 7 discharges wastewater into the other spiral tube 3. The flocculant and wastewater converge at the intersection of the two spiral tubes 3 and are then divided into two liquid streams that flow downward from the two spiral tubes 3. After being divided and twisted, the liquids flow to the next intersection and converge again at the next intersection, quickly and evenly mixing the flocculant and wastewater. After the wastewater reacts with the flocculant, it settles and is discharged after being filtered by the filter plate 11. The flocculant and wastewater are fully mixed without the use of a motor, reducing energy consumption and operating costs.
