Description

Technical Field

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

[0002] At present, the desulfurization wastewater treatment adopts the "reactor (or triple tank) + clarifier" process. The reactor (or triple tank) is used as a container for the reaction of the reagent and the desulfurization wastewater. The slurry is very easy to settle after the reaction. And a considerable part of it enters the clarifier by gravity. In order to ensure that the reagent and the slurry react fully, it is usually done by adding a horizontal plate. The existing addition of wastewater and dosing is carried out at the top of the reactor. As it flows into the reactor, it is inevitable that the reaction will be insufficient due to the stirring dead corner.

[0003] In addition, due to the high chloride ion content in desulfurization wastewater, anti-corrosion requires rubber lining or glass flakes. At this time, for the anti-corrosion operation requirements, the spacing between the horizontal plates is generally large, which makes it easy for the slurry to settle, causing blockage at the bottom and unable to operate normally.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

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

[0030] In general, the present invention proposes a desulfurization wastewater treatment device, including a reactor 1 with an inner cavity formed inside, a horizontal plate 101 vertically fixed inside the reactor 1, a horizontal bar 2 arranged on the top of the reactor 1, a dosing component and a water inlet component rotatably arranged on the horizontal bar 2, a power component fixedly arranged on the horizontal bar 2 and connected to the dosing component and the water inlet component, and a water outlet pipe 9 connected to the reactor 1 at a lower position on the other side of the horizontal plate 101, and 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 transverse plate 101 in the stirred reactor 1 is to guide the wastewater to flow along a predetermined path in the reactor 1, 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 component can guide the wastewater into the reactor 1, the dosing component is used to add the agent for treating the wastewater into the reactor 1, and the power component can drive the water inlet component and the dosing component to rotate and stir while introducing the wastewater and adding the agent, so that the mixing of the agent and the wastewater is more thorough and the reaction is more sufficient.

[0033] Among them, Figures 1 to 4 As shown, the dosing component includes a drug outlet pipe 4 rotatably connected to the cross bar 2 through a first joint 6, and drug outlet holes 401 evenly spaced on the outer circumference of the drug outlet pipe 4, and the drug outlet pipe 4 is located in the reactor 1; the water inlet component includes a water inlet pipe 5 rotatably connected to the cross bar 2 through a second joint 602, and water inlets 502 evenly spaced on the side of the water inlet pipe 5, the water inlet pipe 5 is in the reactor 1, and a plurality of stirring rollers 501 are fixedly spaced on the outer wall of the water inlet pipe 5, and the diameter of the water inlet pipe 5 is larger than that of the drug outlet pipe 4.

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

[0035] During specific implementation, the medicine and wastewater flow into the reactor 1 from the medicine outlet hole 401 and the water inlet 502 at the same time. Since the medicine outlet hole 401 and the water inlet 502 are spread over the medicine outlet pipe 4 and the water inlet pipe 5 from top to bottom, the power component drives it to rotate and form a vortex. Combined with the stirring roller 501, the vortex formed by the medicine outlet pipe 4 and the water inlet pipe 5 can be stirred and mixed, so that the medicine 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, the diameter of the water inlet pipe 5 is larger than the drug outlet pipe 4, which is conducive to achieving a balance between wastewater and drugs.

[0037] The first joint 6 and the second joint 602 are both rotary joints, which can realize 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 joint 6, and a second gear 301 fixedly mounted on the lower part of the second joint 602, the first gear 3 and the second gear 301 are meshed, a motor 303 is fixedly provided on the top of the cross plate 101, a third gear 302 is fixedly provided on the end of the motor 303, and the third gear 302 is meshed with the first gear 3 or the second gear 301.

[0039] During specific implementation, the motor 303 drives the third gear 302 to rotate, transmits power to the second gear 301, and the second gear 301 transmits power to the first gear 3, thereby realizing the rotation of the water inlet pipe 5 and the medicine outlet pipe 4; of course, the power can also be transmitted to the first gear 3, and the first gear 3 transmits power to the second gear 301.

[0040] Preferably, in this embodiment, two groups of dosing components are provided and are located around the water inlet component, so as to realize the function of adding different drugs.

[0041] In order to prevent the wastewater from mixing with the reagent and causing precipitation, which would block the bottom of the reactor 1, Figure 3 and Figure 4 As shown, the bottom end of the water inlet pipe 5 is connected to a nozzle 503 , an inner pipe 504 is arranged inside the water inlet pipe 5 , and the top end of the inner pipe 504 is connected to the second joint 602 .

[0042] During specific implementation, wastewater enters the inner tube 504, and then enters the water inlet pipe 5 through the inner tube 504. The inner diameter of the bottom end of the water inlet pipe 5 is larger than the inner diameter of the nozzle 503, so that the wastewater will spray high-pressure water downward through the nozzle 503 to flush away the sediment at the bottom of the reactor 1 to prevent it from clogging at the bottom.

[0043] As a preferred example, Figure 2 As shown, an upper stirring blade 403 is fixedly provided at the upper position of the medicine outlet pipe 4, and a lower stirring blade 402 is fixedly provided at the lower part. The upper stirring blade 403 and the lower stirring blade 402 are spiral-shaped, and the spiral directions are opposite. In this embodiment, the upper stirring blade 403 and the lower stirring blade 402 rotate to stir the sprayed liquid medicine, increase the contact between the medicine and the wastewater, and thus increase the treatment efficiency. The cylinder 202 can drive the cross bar 2 to slide back and forth on the top of the reactor 1, reducing the stirring dead angle and increasing the reaction effect of the medicine and the wastewater.

[0044] As a preferred structure of the present invention, in order to prevent the gap between the transverse plate 101 and the reactor 1 from being clogged and to increase the processing efficiency, in the present embodiment, a drainage assembly is provided on one side of the transverse plate 101 in the reactor 1, and the drainage assembly includes a vertical pipe 8 in a 7-shape fixedly arranged on the side wall of the transverse plate 101, and the end of the vertical pipe 8 extends to the top of the transverse plate 101 and penetrates the transverse plate 101 and extends into the other side of the transverse plate 101, the bottom end of the vertical pipe 8 is connected to an installation box 801, and the end is connected to a water pump 802 in the installation box 801, and a partition net 803 is fixedly provided at the open portion of the installation box 801.

[0045] In specific implementation, the water pump 802 can suck the sediment in the gap into the vertical pipe 8, and then re-introduce it to the side of the horizontal plate 101 for reaction stirring, thereby increasing the efficiency of the reaction, wherein the provided partition 803 can break up the accumulated sediment and allow it to smoothly enter the vertical pipe 8. It should be noted that in this embodiment, the drainage assembly is preferably provided in three groups.

[0046] In order to facilitate the cleaning of the inside of the reactor 1, in this embodiment, a flushing pipe 901 is connected to the pipeline of the water outlet pipe 9, and a valve 902 is provided on the pipeline of the flushing pipe 901. Water is guided into the reactor 1 through the flushing pipe 901 for cleaning. It should be noted that the valve 902 is closed when the wastewater is treated.

[0047] In this embodiment, in order to reduce the dead angle of stirring and make the reagent and wastewater react completely, in this embodiment, Figure 1 and Figure 2 As shown, extension plates 201 are fixedly provided on both sides of the transverse plate 101 , the transverse plate 101 is slidably connected to the top of the reactor 1 , cylinders 202 are fixedly provided on both sides of the reactor 1 , and the ends of the cylinders 202 are fixedly connected to the extension plates 201 .

[0049] The filter screen 701 has a filtering effect on wastewater and can filter solid impurities to the top of the filter screen 701, making it convenient for the operator to handle.

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