Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a device and method for recovering dechlorinated wastewater from desulfurized gypsum. Background Technology

[0002] Desulfurized gypsum is a major byproduct of wet flue gas desulfurization in coal-fired power plants. The chloride ions it contains severely impact its subsequent resource utilization; for example, when used in building material production, it can easily lead to problems such as efflorescence, steel reinforcement corrosion, and reduced strength. Therefore, dechlorination treatment is usually required for desulfurized gypsum, a process that generates large amounts of high-chlorine wastewater. Currently, the common method for treating this type of desulfurized gypsum dechlorination wastewater is to add chemical agents to the wastewater and stir to ensure thorough mixing and reaction, thereby effectively reducing the chloride ion concentration in the wastewater and facilitating subsequent recycling or achieving compliant discharge.

[0003] However, existing recycling equipment often uses a stirring rod to stir in the same direction, resulting in poor mixing effect and low mixing efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a desulfurized gypsum dechlorination wastewater recovery device and method, which solves the technical problem that in the prior art, stirring rods are often used to stir in the same direction, resulting in poor mixing effect and low mixing efficiency.

[0005] To achieve the above objectives, the present invention provides a desulfurization gypsum dechlorination wastewater recovery device, comprising a tank, a reagent tube, and a mixing mechanism. The tank has an inlet and an outlet. The mixing mechanism includes a lifting component, two rotary joints, two rotating pipes, multiple diffusion pipes, two meshing parts, a rack, a sliding part, a connecting part, and a supporting component. The lifting component is mounted on the tank. The reagent tube is connected to the lifting component. The two rotating pipes are respectively connected to the reagent tubes through corresponding rotary joints. The diffusion pipes are connected to the corresponding rotating pipes. Both meshing parts are rotatably connected to the lifting component. The rotating pipes are slidably connected to the corresponding meshing parts. The sliding parts are slidably connected to the lifting component. The rack is fixedly connected to the sliding parts. The connecting part is fixedly connected to the sliding parts. The supporting component is used to drive the connecting part to move.

[0006] The supporting component includes a motor, a disc, a supporting rod, a follower, and a support rod. The housing has a sliding groove, the support rod is slidably connected to the sliding groove, the follower is fixedly connected to the support rod, and the follower has a through hole. The motor is mounted on the housing, and the output end of the motor is fixedly connected to the disc. One end of the supporting rod is fixedly connected to the disc, and the other end of the supporting rod is placed in the through hole.

[0007] The connecting member includes a connecting rod and two round rods. The follower has two round holes. The connecting rod is fixedly connected to the sliding member. One end of the two round rods is fixedly connected to the connecting rod, and the other end of the two round rods passes through the corresponding round holes.

[0008] The sliding component includes a sliding rod and a bracket. The lifting component has a guide groove. The sliding rod is slidably connected to the guide groove. The bracket is fixedly connected to the sliding rod. The bracket is fixedly connected to the rack and the connecting rod.

[0009] The lifting component includes two cylinders, two lugs, and a displacement plate. The cylinders are mounted on the housing, and the output end of the cylinder is fixedly connected to the corresponding lug. The displacement plate is fixedly connected to both lugs.

[0010] The meshing component includes a rotating component and a gear. The rotating component is rotatably connected to the displacement plate, the gear is fixedly connected to the rotating component, and the gear meshes with the rack.

[0011] This invention also provides a method for recovering dechlorination wastewater from desulfurized gypsum, using the dechlorination wastewater recovery equipment described above. Wastewater is introduced into the tank through the inlet; The supporting member is activated, causing it to move the connecting member. The connecting member then moves the sliding member on the lifting member. As the sliding member moves, it drives the rack to reciprocate laterally. The rack reciprocates laterally, thereby driving the two meshing parts to rotate reciprocally, and the two meshing parts rotate reciprocally, thereby driving the two rotating tubes to rotate reciprocally. During this process, the agent in the agent tube enters the two rotating tubes through the two rotating joints, and the agent in the two rotating tubes is diffused into the wastewater in the tank through the diffusion holes on the multiple diffusion tubes. At this time, the diffusion tubes are in a rotating state. The lifting component is activated, causing it to indirectly drive the diffusion tube to reciprocate up and down. The treated wastewater is discharged through the outlet.

[0012] This invention discloses a desulfurization gypsum dechlorination wastewater recovery device and method. In practical use, wastewater enters the tank through the inlet. Then, the supporting member is activated, which drives the connecting member to move. The connecting member then drives the sliding member to slide on the lifting member. Simultaneously, the sliding member moves, causing the rack to reciprocate laterally. The rack's reciprocating motion further drives the two meshing members to rotate reciprocally. The two meshing members' reciprocating rotation further drives the two rotating pipes to rotate. During this process, the reagent in the reagent pipe enters the two rotating joints. The agent in the two rotating tubes is diffused into the wastewater in the tank through the diffusion holes on the multiple diffusion tubes. At this time, the diffusion tubes are rotating, so that the agent can come into contact with the wastewater more comprehensively. At the same time, the lifting component can indirectly drive the diffusion tubes to move up and down, further improving the mixing effect. The treated wastewater can be discharged through the outlet for further treatment. This method solves the technical problem in the prior art that the mixing effect is poor and the mixing efficiency is low when the stirring rod is used to stir in the same direction.

Figure 3 This is the front view of the present invention. Figure 4 This is a side view of the present invention.

This embodiment of the invention provides a desulfurized gypsum dechlorination wastewater recovery device, including a housing 1, a reagent tube 2, and a mixing mechanism. The mixing mechanism includes a lifting component, two rotary joints 3, two rotating tubes 4, multiple dispersion tubes 5, two meshing parts, a rack 6, a sliding part, a connecting part, and a supporting component. The supporting component includes a motor 7, a disc 8, a supporting rod 9, a follower 10, and a support rod 11. The connecting part includes a connecting rod 12 and two round rods 13. The sliding part includes a sliding rod 14 and a bracket 15. The lifting component includes two cylinders 16, two lugs 17, and a displacement plate 18. The meshing part includes a rotating part 19 and a gear 20. The aforementioned solution solves the technical problem in the prior art where stirring rods are often used in the same direction during use, resulting in poor mixing effect and low mixing efficiency.

[0023] In this specific embodiment, the tank 1 has an inlet 21 and an outlet 22. Wastewater enters the tank 1 through the inlet 21 and is discharged through the outlet 22 after treatment.

[0024] The lifting component is mounted on the housing 1. The medicine tube 2 is connected to the lifting component. Two rotating tubes 4 are connected to the medicine tube 2 via corresponding rotary joints 3. The diffusion tube 5 is connected to the corresponding rotating tube 4. Both meshing parts are rotatably connected to the lifting component. The rotating tube 4 is slidably connected to the corresponding meshing part. The sliding part is slidably connected to the lifting component. The rack 6 is fixedly connected to the sliding part. The connecting part is fixedly connected to the sliding part. The abutting component is used to drive the connecting part to move. In actual use, wastewater enters the housing 1 through the inlet 21. Then, the abutting component is activated, which drives the connecting part to move. The connecting part then drives the sliding part to slide on the lifting component. While the sliding part moves, it drives the rack 6 to reciprocate laterally. The rack 6 moves laterally and reciprocates, which in turn drives the two meshing parts to rotate reciprocally. The reciprocating rotation of the two meshing parts drives the two rotating tubes 4 to rotate. During this process, the agent in the agent tube 2 enters the two rotating tubes 4 through the two rotary joints 3. The agent in the two rotating tubes 4 is diffused into the wastewater in the tank 1 through the diffusion holes on the multiple diffusion tubes 5. At this time, the diffusion tubes 5 are in a rotating state, so that the agent can come into contact with the wastewater more comprehensively. At the same time, the lifting component can indirectly drive the diffusion tubes 5 to move up and down, further improving the mixing effect. The treated wastewater is discharged through the outlet 22 for further treatment. This method solves the technical problem in the prior art that the mixing effect is poor and the mixing efficiency is low when the stirring rod is used to stir in the same direction.

[0025] Secondly, the housing 1 has a sliding groove 23, the support rod 11 is slidably connected to the sliding groove 23, the follower 10 is fixedly connected to the support rod 11, the follower 10 has a through hole 24, the motor 7 is mounted on the housing 1, the output end of the motor 7 is fixedly connected to the disc 8, one end of the abutment rod 9 is fixedly connected to the disc 8, and the other end of the abutment rod 9 is placed in the through hole 24. When the motor 7 is started, the output end of the motor 7 drives the disc 8 to rotate. While the disc 8 rotates, it drives the abutment rod 9 to slide in the through hole 24. While the abutment rod 9 slides in the through hole 24, it drives the follower 10 to move. The follower 10 then drives the support rod 11 to slide in the sliding groove 23, and the follower 10 drives the connecting member to move.

[0026] Meanwhile, the follower 10 has two circular holes 25, the connecting rod 12 is fixedly connected to the sliding member, one end of the two circular rods 13 is fixedly connected to the connecting rod 12, and the other end of the two circular rods 13 passes through the corresponding circular holes 25. When the follower 10 moves, it drives the circular rods 13 to move. When the circular rods 13 move, they drive the connecting rod 12 to move, which in turn drives the sliding member to move.

[0027] Furthermore, the lifting component has a guide groove 26, the slide rod 14 is slidably connected to the guide groove 26, the bracket 15 is fixedly connected to the slide rod 14, the bracket 15 is fixedly connected to the rack 6 and the connecting rod 12, when the connecting rod 12 moves, it drives the bracket 15 to move laterally, the bracket 15 drives the slide rod 14 to slide in the guide groove 26, the slide rod 14 is used to guide the bracket 15, and the bracket 15 drives the rack 6 to move.

[0028] Furthermore, the cylinder 16 is mounted on the housing 1, and the output end of the cylinder 16 is fixedly connected to the corresponding support lug 17. The displacement plate 18 is fixedly connected to both of the support lugs 17. When the cylinder 16 is started, the cylinder 16 drives the corresponding support lug 17 to move, and the support lug 17 in turn drives the displacement plate 18 to move.

[0029] The rotating component 19 is rotatably connected to the displacement plate 18, the gear 20 is fixedly connected to the rotating component 19, and the gear 20 meshes with the rack 6. When the rack 6 moves, it drives the gear 20 to rotate, the gear 20 drives the corresponding rotating component 19 to rotate, and the rotating component 19 in turn drives the corresponding rotating tube 4 to rotate.

[0030] The desulfurized gypsum dechlorination wastewater recovery equipment also includes a hose 27, a nozzle 28, and a connecting block 29. The hose 27 is disposed between the agent tube 2 and the nozzle 28. The two ends of the connecting block 29 are fixedly connected to the nozzle 28 and the bracket 15, respectively. The nozzle 28 is used to spray the agent in the agent tube 2 into the wastewater in the tank 1. When the bracket 15 moves, it drives the connecting block 29 to move, and the connecting block 29 in turn drives the nozzle 28 to move laterally, thereby increasing the spraying range.

[0031] This invention also provides a method for recovering dechlorination wastewater from desulfurized gypsum, using the dechlorination wastewater recovery equipment described above. Wastewater is introduced into the tank 1 through the inlet 21; The abutting member is activated, causing the abutting member to move the connecting member. The connecting member then causes the sliding member to slide on the lifting member. As the sliding member moves, it causes the rack 6 to reciprocate laterally. The rack 6 reciprocates laterally, thereby driving the two meshing parts to rotate reciprocally, and the two meshing parts rotate reciprocally, thereby driving the two rotating tubes 4 to rotate reciprocally. During this process, the agent in the agent tube 2 enters the two rotating tubes 4 through the two rotating joints 3, and the agent in the two rotating tubes 4 is diffused into the wastewater in the tank 1 through the diffusion holes on the multiple diffusion tubes 5. At this time, the diffusion tubes 5 are in a rotating state. The lifting component is activated, causing it to indirectly drive the diffusion tube 5 to move up and down reciprocally. The treated wastewater is discharged through the outlet 22.

[0032] In a desulfurization gypsum dechlorination wastewater recovery device and method of the present invention, wastewater enters the tank 1 through the inlet 21. Then, the supporting member is activated, which drives the connecting member to move. The connecting member then drives the sliding member to slide on the lifting member. Simultaneously, the sliding member moves, causing the rack 6 to reciprocate laterally. The reciprocating motion of the rack 6 further drives the two meshing members to rotate reciprocally. The reciprocating rotation of the two meshing members further drives the two rotating pipes 4 to rotate. During this process, the reagent in the reagent pipe 2 enters the two rotating joints 3. The agent in the two rotating tubes 4 is diffused into the wastewater in the tank 1 through the diffusion holes on the multiple diffusion tubes 5. At this time, the diffusion tubes 5 are rotating, so that the agent can come into contact with the wastewater more comprehensively. At the same time, the lifting component can indirectly drive the diffusion tubes 5 to move up and down, further improving the mixing effect. The treated wastewater can be discharged through the outlet 22 for further treatment. This method solves the technical problem in the prior art that the mixing effect is poor and the mixing efficiency is low when the stirring rod is used to stir in the same direction.
