Description

Technical Field

[0001] This invention relates to the field of wastewater treatment, and in particular to a desulfurization wastewater treatment device. Background Technology

[0002] Currently, desulfurization wastewater treatment employs a "reactor (or triplex tank) + clarifier" process. The reactor (or triplex tank) serves as the container for the reaction between the reagents and the desulfurization wastewater, and the resulting slurry is prone to sedimentation. Furthermore, a significant portion flows into the clarifier by gravity. To ensure sufficient reaction between the reagents and the slurry, a horizontal plate is typically added. Currently, wastewater and reagent addition occur at the top of the reactor, and as the slurry flows into the reactor, dead zones inevitably lead to incomplete reactions due to poor agitation.

[0003] In addition, due to the high chloride ion content in desulfurization wastewater, corrosion protection requires rubber lining or glass flakes. In this case, the spacing between the horizontal plates is generally large, which makes the slurry easy to settle, causing blockage at the bottom and preventing normal operation. Summary of the Invention

[0004] In view of this, the present invention aims to provide a desulfurization wastewater treatment device to solve the problems in the prior art.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0006] This invention proposes a desulfurization wastewater treatment device, comprising a reactor with an internal cavity, a horizontal plate vertically fixed inside the reactor, a horizontal bar on the top of the reactor, a dosing assembly and a water inlet assembly rotatably mounted on the horizontal bar, a power assembly fixedly mounted on the horizontal bar and connected to the dosing assembly and the water inlet assembly, and an outlet pipe connected to the reactor at a lower position on the other side of the horizontal plate. There is a gap between the bottom end of the horizontal bar and the bottom surface of the reactor.

[0007] The dosing assembly includes a dosing pipe rotatably connected to the crossbar via a first connector, and dosing holes evenly spaced around the outer circumference of the dosing pipe, the dosing pipe being located inside the reactor;

[0008] The water inlet assembly includes a water inlet pipe rotatably connected to the crossbar via a second connector, and water inlets evenly spaced around the water inlet pipe. The water inlet pipe is inside the reactor, and multiple stirring rollers are fixedly spaced on the outer wall of the water inlet pipe. The diameter of the water inlet pipe is larger than that of the drug outlet pipe.

[0009] Furthermore, the power assembly includes a first gear fixedly mounted on the lower part of the first connector and a second gear fixedly mounted on the lower part of the second connector. The first gear and the second gear mesh with each other. A motor is fixedly mounted on the top of the cross plate, and a third gear is fixedly mounted on the end of the motor. The third gear meshes with the first gear or the second gear.

[0010] Furthermore, a nozzle is connected to the bottom end of the water inlet pipe, and an inner pipe is provided inside the water inlet pipe, with the top end of the inner pipe connected to the second connector.

[0011] Furthermore, an upper stirring plate is fixedly provided at the upper part of the dispensing tube, and a lower stirring plate is fixedly provided at the lower part. The upper and lower stirring plates are spiral in shape and the spiral directions are opposite.

[0012] Furthermore, a flow-guiding assembly is provided inside the reactor on one side of the horizontal plate. The flow-guiding assembly includes a vertical pipe in the shape of a "7" that is fixedly installed on the side wall of the horizontal plate. The end of the vertical pipe extends to the top of the horizontal plate and penetrates the horizontal plate to the other side of the horizontal plate. The bottom end of the vertical pipe is connected to an installation box, and the end is connected to a water pump inside the installation box. A mesh is fixedly installed at the opening of the installation box.

[0013] Furthermore, extension plates are fixedly provided on both sides of the horizontal plate, the horizontal plate is slidably connected to the top of the reactor, and cylinders are fixedly provided on both sides of the reactor, with the ends of the cylinders fixedly connected to the extension plates.

[0014] Furthermore, a flushing pipe is connected to the outlet pipe, and a valve is installed on the flushing pipe.

[0015] Furthermore, the second connector is connected to a connecting pipe at its end, and a water inlet hopper is connected to the top of the connecting pipe. A strainer is fixedly installed on the water inlet hopper.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] In this invention, the inlet assembly guides wastewater into the reactor, the dosing assembly adds the wastewater treatment agent into the reactor, and the power assembly drives the inlet and dosing assemblies to rotate and stir simultaneously during wastewater introduction and agent addition, ensuring more thorough mixing and a more complete reaction between the agent and wastewater. The agent and wastewater flow into the reactor simultaneously from the outlet and inlet. Since the outlet and inlet are distributed from top to bottom as outlet pipes and inlet pipes, the rotation driven by the power assembly creates a vortex. Combined with the stirring roller, this vortex from the outlet and inlet pipes is stirred and mixed, ensuring a thorough mixing and reaction between the agent and wastewater.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

They are used only for the convenience of describing this invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] Furthermore, in the description of this invention, unless otherwise explicitly defined, the terms "installation," "connection," "linking," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention in light of the specific circumstances.

[0029] The following will refer to the appendix. Figures 1 to 5 The present invention will be described in detail with reference to the embodiments.

[0030] Overall, the present invention proposes a desulfurization wastewater treatment device, including a reactor 1 with an internal cavity, a horizontal plate 101 vertically fixed inside the reactor 1, a horizontal bar 2 set on the top of the reactor 1, a dosing assembly and a water inlet assembly rotatably set on the horizontal bar 2, a power assembly fixedly set on the horizontal bar 2 and connected to the dosing assembly and the water inlet assembly, and an outlet pipe 9 connected to the reactor 1 at a lower position on the other side of the horizontal plate 101. There is a gap between the bottom end of the horizontal bar 2 and the bottom surface of the reactor 1.

[0031] It should be understood that the main function of the horizontal plate 101 in the stirred reactor 1 is to guide the wastewater to flow in the reactor 1 along a predetermined path, ensuring that the wastewater and the reagent can be fully mixed and reacted, thereby improving the treatment efficiency.

[0032] In this embodiment, the water inlet assembly guides wastewater into reactor 1, the dosing assembly adds the wastewater treatment agent into reactor 1, and the power assembly drives the water inlet assembly and the dosing assembly to rotate and stir while introducing wastewater and adding chemicals, so that the mixing of chemicals and wastewater is more thorough and the reaction is more complete.

[0033] Among them, such as Figures 1 to 4 As shown, the dosing assembly includes a dosing pipe 4 rotatably connected to the crossbar 2 via a first connector 6, and dosing holes 401 evenly spaced on the outer circumference of the dosing pipe 4. The dosing pipe 4 is located inside the reactor 1. The water inlet assembly includes a water inlet pipe 5 rotatably connected to the crossbar 2 via a second connector 602, and water inlets 502 evenly spaced on the periphery of the water inlet pipe 5. The water inlet pipe 5 is located inside the reactor 1. Multiple stirring rollers 501 are fixedly spaced on the outer wall of the water inlet pipe 5. The diameter of the water inlet pipe 5 is larger than that of the dosing pipe 4.

[0034] It should be noted that the top of the first connector 6 is connected to the external equipment, and the bottom is connected to the outlet pipe 4, which is used to introduce the treatment agent into the outlet pipe 4 and flow out through the outlet hole 401. Similarly, the top of the second connector 602 is connected to the external equipment, which leads the wastewater into the inlet pipe 5 and flows out of the reactor 1 through the inlet 502.

[0035] In practice, the reagent and wastewater flow into the reactor 1 simultaneously from the reagent outlet 401 and the water inlet 502. Since the reagent outlet 401 and the water inlet 502 are distributed from top to bottom through the reagent outlet pipe 4 and the water inlet pipe 5, the rotation driven by the power component can form a vortex. Combined with the stirring roller 501, the vortex formed by the reagent outlet pipe 4 and the water inlet pipe 5 can be stirred and mixed, so that the reagent and wastewater can be fully mixed and reacted.

[0036] It should be further explained that the dosing assembly and the water inlet assembly are located on the same side of the horizontal plate 101. In addition, when setting them up, the diameter of the water inlet pipe 5 is larger than that of the outlet pipe 4, which is conducive to achieving a balance between wastewater and chemicals.

[0037] Both the first connector 6 and the second connector 602 mentioned above are rotary connectors, which can achieve the rotation function without affecting the flow of liquid.

[0038] like Figure 1 and Figure 2 As shown, the power assembly includes a first gear 3 fixedly mounted on the lower part of the first connector 6 and a second gear 301 fixedly mounted on the lower part of the second connector 602. The first gear 3 and the second gear 301 mesh with each other. A motor 303 is fixedly mounted on the top of the horizontal plate 101. A third gear 302 is fixedly mounted on the end of the motor 303. The third gear 302 meshes with the first gear 3 or the second gear 301.

[0039] In practice, the motor 303 drives the third gear 302 to rotate, transmitting power to the second gear 301, which in turn transmits power to the first gear 3, thereby enabling the rotation of the water inlet pipe 5 and the medicine outlet pipe 4. Alternatively, the power can be transmitted to the first gear 3, which in turn transmits power to the second gear 301.

[0040] Preferably, in this embodiment, two sets of dosing components are provided and located around the water inlet component. This enables the addition of different chemicals.

[0041] To prevent sedimentation from forming after the wastewater mixes with the reagents, which could cause blockage at the bottom of reactor 1, such as... Figure 3 and Figure 4 As shown, the bottom end of the water inlet pipe 5 is connected to a nozzle 503, and the water inlet pipe 5 is provided with an inner pipe 504. The top end of the inner pipe 504 is connected to the second connector 602.

[0042] In practice, wastewater enters the inner pipe 504 and then enters the inlet pipe 5 through the inner pipe 504. The inner diameter of the bottom end of the inlet pipe 5 is larger than the inner diameter of the nozzle 503, so that the wastewater will be sprayed downward through the nozzle 503 to flush away the sediment at the bottom of the reactor 1 and prevent it from clogging the bottom.

[0043] As a preferred option, such as Figure 2 As shown, an upper stirring plate 403 is fixedly installed at the upper part of the dispensing pipe 4, and a lower stirring plate 402 is fixedly installed at the lower part. The upper stirring plate 403 and the lower stirring plate 402 are spiral in shape and in opposite directions. In this embodiment, the rotation of the upper stirring plate 403 and the lower stirring plate 402 can stir the sprayed liquid, increase the contact between the agent and the wastewater, and thus increase the treatment efficiency. The cylinder 202 can drive the crossbar 2 to slide back and forth on the top of the reactor 1, reducing the dead zone of stirring and increasing the reaction effect between the agent and the wastewater.

[0044] As a preferred structure of the present invention, in order to prevent the gap between the horizontal plate 101 and the reactor 1 from becoming clogged and to increase the processing efficiency, in this embodiment, a flow guiding assembly is provided on one side of the horizontal plate 101 inside the reactor 1. The flow guiding assembly includes a vertical pipe 8 in the shape of a "7" fixedly installed on the side wall of the horizontal plate 101. The end of the vertical pipe 8 extends to the top of the horizontal plate 101 and passes through the horizontal plate 101 to extend into the other side of the horizontal plate 101. The bottom end of the vertical pipe 8 is connected to a mounting box 801, and the end is connected to a water pump 802 inside the mounting box 801. A partition net 803 is fixedly installed at the opening of the mounting box 801.

[0045] In practice, the water pump 802 can draw the sediment from the gaps into the vertical pipe 8, and then guide it back to one side of the horizontal plate 101 for reaction and stirring, thereby increasing the reaction efficiency. The partition screen 803 can break up the accumulated sediment, allowing it to smoothly enter the vertical pipe 8. It should be noted that in this embodiment, three sets of the diversion components are preferably provided.

[0046] To facilitate cleaning of the interior of reactor 1, in this embodiment, a flushing pipe 901 is connected to the outlet pipe 9, and a valve 902 is installed on the flushing pipe 901. Water is guided into reactor 1 through the flushing pipe 901 for cleaning. It should be noted that valve 902 is in the closed state during wastewater treatment.

[0047] In this embodiment, to reduce dead zones in the stirring and ensure a thorough reaction between the reagent and the wastewater, as follows: Figure 1 and Figure 2 As shown, extension plates 201 are fixedly provided on both sides of the horizontal plate 101. The horizontal plate 101 is slidably connected to the top of the reactor 1. Cylinders 202 are fixedly provided on both sides of the reactor 1. The ends of the cylinders 202 are fixedly connected to the extension plates 201.

[0048] In addition, such as Figures 1 to 3 As shown, in order to prevent the wastewater entering the inlet pipe 5 from carrying solid impurities, in this embodiment, the end of the second connector 602 is connected to a connecting pipe 702, the top of the connecting pipe 702 is connected to an inlet hopper 7, and a strainer 701 is fixedly installed on the inlet hopper 7.

[0049] The strainer 701 filters wastewater, filtering solid impurities to the top of the strainer for easy handling by the operator.

[0050] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. 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.
