Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a multi-point water distribution type water treatment flocculation reaction device. Background Technology

[0002] In recent years, with the increasing prominence of global environmental problems and the growing emphasis placed on water pollution control by governments worldwide, the water treatment market has been expanding. Flocculation reaction units play a crucial role in water treatment.

[0003] Flocculation is a process in which chemical agents (such as flocculants) are pre-added to wastewater to disrupt the stability of colloids in the wastewater, causing colloids and fine suspended solids to aggregate into separable flocs, which are then separated and removed. It is mainly used to remove suspended solids, turbidity, color, oil, pathogens, and viruses from water. Flocculation is suitable for treating various types of polluted raw water and industrial wastewater, including wastewater from knitting and dyeing, pulp and paper making, wastewater containing heavy metals, converter dust removal wastewater, and mine wastewater.

[0004] The current conventional flocculation processes mainly include: baffle flocculation tank, perforated cyclone flocculation tank and mechanically stirred flocculation tank.

[0005] A baffle flocculation tank is formed by installing horizontal or vertical baffles in the water channel, which creates a gradually decreasing velocity gradient in the water flow after chemical mixing, thereby causing particles to contact, collide, and aggregate, forming large flocs.

[0006] A perforated vortex flocculation tank is a flocculation tank consisting of several interconnected water chambers, each with an opening (usually a square opening) on ​​the upper or lower left or right side of the inlet and outlet partition walls. The arrangement of the openings in each chamber is such that the inlet and outlet are staggered, so that the inflowing water forms a vortex, thereby enabling the water flow and the added coagulant to carry out a flocculation reaction process.

[0007] A mechanically stirred flocculation tank is a water treatment device that promotes the collision of particles in water through mechanical agitation, forming flocs. It mainly consists of an agitator, a tank body, and baffles, typically employing a horizontal-axis or vertical-axis paddle-type flocculation mixer. The agitator is driven by an electric motor to stir the water, causing the particles to collide and flocculate.

[0008] However, existing flocculation processes have various problems:

[0009] The flow conditions in the baffled flocculation tank are not ideal, thus requiring a longer flocculation time and resulting in a larger tank volume. A significant proportion of energy consumption is wasted, leading to substantial head loss. At sharp corners, the probability of particle collision increases, easily causing floc breakage. When the flow rate is too low, the baffle spacing is too narrow, making construction and maintenance inconvenient.

[0010] The flocculation effect of perforated vortex flocculation tanks is greatly affected by the flow rate. When the flow rate changes, the arrangement of the orifices and the formation of the vortex are affected, resulting in poor flocculation. In addition, the uneven flow of water in the tank makes it easy for sludge to accumulate at the bottom.

[0011] Mechanically stirred flocculation tanks require significant energy consumption to achieve efficient flocculation. Furthermore, the equipment is prone to malfunctions, necessitating regular maintenance and repairs, which increases maintenance costs and downtime. Additionally, mechanically stirred flocculation tanks may experience short-circuiting in the reaction tank and unstable water flow, leading to unsatisfactory flocculation results and low reagent utilization. Summary of the Invention

[0012] To address the shortcomings of existing technologies, this invention provides a multi-point water distribution type water treatment flocculation reaction device. Bottom water inlet solves the problem of sludge accumulation at the bottom of the flocculation tank. Multi-point water distribution increases the contact conditions between the chemical solution and the wastewater, improving the utilization efficiency of the chemical solution. After passing through the water distribution head, the wastewater and chemical solution form a stable vortex that gradually increases in size, enhancing the floc formation effect. The wastewater after the flocculation reaction exits through the upper water guide hole, ensuring stable effluent flow and solving the problem of floc formation followed by deflocculation.

[0013] To achieve the above objectives, this utility model employs the following technical solution:

[0014] A multi-point water distribution type water treatment flocculation reaction device includes a reaction tank. An inlet pipe is provided at the bottom of the side wall of the reaction tank. The inside of the reaction tank is arranged sequentially from bottom to top as a wastewater distribution zone, a flocculation reaction zone, a flocculation flow stabilization zone, and a chemical solution distribution zone. A chemical solution inlet pipe is provided at the top of the reaction tank. An outlet pipe is provided on the side wall of the reaction tank. The inlet pipe is connected to the wastewater distribution zone.

[0015] Furthermore, the flocculation reaction zone includes an inlet flow stabilizing plate, multiple drug inlet pipes, and a conical water distribution head located at the bottom of the drug inlet pipes. The inlet flow stabilizing plate is provided with multiple flow stabilizing plate holes, and the conical water distribution head is located within the flow stabilizing plate holes.

[0016] Furthermore, the flocculation flow stabilization zone includes a flocculation flow stabilization plate, and the drug inlet pipe extends upward through the flocculation flow stabilization plate.

[0017] Furthermore, the liquid distribution area includes a liquid distribution plate, which is provided with multiple liquid distribution holes, each of which is connected to a port of the inlet pipe.

[0018] Furthermore, the conical water distribution head includes a water guiding cone, a medicine dispensing cone is provided at the top of the water guiding cone, a medicine dispensing hole is provided on the medicine dispensing cone, and a connecting rod with an internal cavity is provided at the top of the medicine dispensing cone, with external threads provided on the outer side of the top of the connecting rod.

[0019] Furthermore, annular protrusions are provided around the upper surface of the liquid distribution holes.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. This device solves the problem of easy sludge accumulation at the bottom of the flocculation tank by introducing water from the bottom; and by distributing water at multiple points, it increases the contact conditions between the chemical solution and the wastewater, thereby improving the utilization efficiency of the chemical solution; after the wastewater passes through the water distribution head, the chemical solution and wastewater form a stable vortex that gradually increases in size, which improves the floc formation effect; the wastewater after the flocculation reaction exits through the upper water guide hole, resulting in stable effluent, thus solving the problem of floc formation followed by deflocculation.

[0022] 2. This device is arranged on-site according to the actual water level. Wastewater flows in and out by its own pressure, without the need for power transportation. The wastewater and the chemical solution spontaneously form a vortex according to the internal structure of the equipment, without the need for mixing equipment, which greatly reduces the energy consumption of operation.

[0023] 3. The conical water head comes in various styles and is detachable, allowing for matching to different water qualities in different industries. It can also be adjusted and replaced according to the physical state of the added chemical solution, such as viscosity, density, and particle size. Attached Figure Description

[0038] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined in this application.

[0039] like Figure 1-5 As shown, a multi-point water distribution type water treatment flocculation reaction device is disclosed, including a reaction tank 8. A water inlet pipe 1 is provided at the bottom of the side wall of the reaction tank 8. The inside of the reaction tank 8 is arranged sequentially from bottom to top as a wastewater distribution zone 2, a flocculation reaction zone 3, a flocculation flow stabilization zone 4, and a chemical solution distribution zone 5. A chemical solution inlet pipe 7 is provided at the top of the reaction tank 8. A water outlet pipe 6 is provided on the side wall of the reaction tank 8. The water inlet pipe 1 is connected to the wastewater distribution zone 2.

[0040] Specifically, the flocculation reaction zone 3 includes an inlet flow stabilizing plate 32, multiple drug inlet pipes 34, and a conical water distribution head 33 located at the bottom of the drug inlet pipes 34. The inlet flow stabilizing plate 32 is provided with multiple flow stabilizing plate holes 31, and the conical water distribution head 33 is located inside the flow stabilizing plate holes 31.

[0041] The flocculation and flow stabilization zone 4 includes a flocculation and flow stabilization plate 41, and the drug inlet pipe 34 extends upward through the flocculation and flow stabilization plate 41.

[0042] The liquid distribution area 5 includes a liquid distribution plate 51, on which a plurality of liquid distribution holes 52 are provided, and each liquid distribution hole 52 is connected to a port of the inlet pipe 34.

[0043] The processing steps of this device are as follows:

[0044] S1. Wastewater enters the bottom of reaction tank 8 through inlet pipe 1 and gathers in wastewater distribution area 2. The wastewater in wastewater distribution area 2 is in a turbulent state.

[0045] S2. Turbulent sewage in sewage distribution zone 2 flows upward and undergoes initial water distribution after passing through the inlet flow stabilizer plate hole 31 to reduce the intensity of sewage turbulence before continuing to flow upward.

[0046] S3. The liquid medicine enters the liquid medicine distribution zone 5 through the liquid medicine inlet pipe 7. After being homogenized in the liquid medicine distribution zone 5, the liquid medicine passes evenly through the liquid medicine distribution plate 51 through the liquid medicine distribution hole 52, and enters the flocculation reaction zone 3 through the liquid medicine inlet pipe 34 and the conical water distribution head 33.

[0047] S4. The chemical solution and wastewater form a stable vortex that gradually increases in size in the flocculation reaction zone 3 and flow upwards slowly.

[0048] S5. The mixed liquid in the flocculation reaction zone 3 passes through the flocculation flow stabilization plate 41, causing the sewage flow state to change from vortex to laminar flow before entering the flocculation flow stabilization zone 4.

[0049] S6. The mixed liquid entering the flocculation and stabilization zone 4 is discharged through the outlet pipe 6, completing the coagulation and chemical reaction process.

[0050] Among them, such as Figure 3 As shown, the conical water distribution head 33 includes a water guiding cone 331, a medicine dispensing cone 332 is provided at the top of the water guiding cone 331, a medicine dispensing hole 333 is provided on the medicine dispensing cone 332, and a connecting rod 334 with an internal cavity is provided at the top of the medicine dispensing cone 332. The connecting rod 334 has an external thread on the outer side of its top, and is connected to the medicine inlet pipe 34 through the external thread of the connecting rod. The medicine enters into the medicine dispensing cone 332 and flows out through the medicine dispensing hole 333.

[0051] The entire conical water distribution head 33 can be replaced according to the type and requirements of the added liquid. The replaced discharge cone head 332 has different forms, such as 6 small round holes, 4 large round holes, and 6 square holes.

[0052] The preferred liquid distribution hole 52 is non-planar. The upper surface of the liquid distribution hole 52 is provided with annular protrusions around the perimeter. After the liquid enters the liquid distribution area 5, it will not immediately enter the adjacent inlet pipe 32. Instead, it will first accumulate in the liquid distribution area 5. When the accumulated liquid height exceeds the annular protrusion, it will overflow into the inlet pipe 32. Therefore, the liquid is evenly fed through the annular protrusion. All the elevations of the annular protrusion are the same, ensuring that the liquid flows evenly from the liquid distribution hole 52 into the distribution pipe and the inlet pipe.

[0053] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
