Abstract
Description
Technical Field
[0001] This application relates to the field of wastewater treatment technology, and more specifically, to a desulfurization wastewater treatment system and method. Background Technology
[0002] Desulfurization wastewater mainly consists of the discharge water from the absorption tower during the wet desulfurization (limestone / gypsum method) of boiler flue gas. To maintain the material balance in the desulfurization unit's slurry circulation system, prevent the concentration of soluble components (chlorine) in the flue gas from exceeding the specified value, and ensure the quality of the gypsum, a certain amount of wastewater must be discharged from the system. This wastewater primarily originates from the gypsum dewatering and cleaning system. The impurities contained in the wastewater mainly include suspended solids, supersaturated sulfites, sulfates, and heavy metals.
[0003] Research revealed that traditional desulfurization wastewater treatment processes are complex. The desulfurization wastewater is slightly acidic, and the use of wastewater hydrocyclones results in high overflow concentrations, making manual adjustments difficult. Furthermore, a wide variety of chemicals are used, and the chemicals have poor stability. In addition, the sludge equipment has a high failure rate, leading to high levels of heavy metals, fluorides, and COD in the desulfurization wastewater.
[0004] Traditional desulfurization wastewater treatment processes often struggle to remove heavy metals and COD from wastewater, hindering its compliance with discharge standards. Furthermore, the dosing equipment, typically installed at the top of the wastewater treatment plant, is difficult, cumbersome, energy-intensive, and labor-intensive. Additionally, the sludge deposited at the bottom of the treatment plant after purification is difficult to remove. Therefore, this paper proposes a desulfurization wastewater treatment system and method. Summary of the Invention

[0050] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them.

[0051] Example
[0052] like Figures 1-7 As shown, the desulfurization wastewater treatment system according to an embodiment of this application includes a three-compartment assembly 100 for collecting and purifying desulfurization wastewater. The three-compartment assembly 100 includes a purification box 110. The purification box 110 consists of a neutralization box 111, a reaction box 112, and a flocculation box 113, and is used for multi-layer purification of desulfurization wastewater. A lower support box 120 is fixedly connected to the bottom of the purification box 110 for storing and installing the feeding assembly 300 and the sewage discharge assembly 400.
[0053] The bottom of the lower support box 120 is provided with a slide rail 121 for auxiliary movement of the pump body 330. The front end of the lower support box 120 is provided with a sliding groove 122 for the movement of the pipeline. The front end of the purification box 110 is connected with a side plate 130 to increase the overall aesthetics of the triple box assembly 100.
[0054] An integrated treatment process is adopted, which utilizes the neutralization box 111, reaction box 112 and flocculation box 113 on the purification box 110 and directly supplies chemicals through the storage component 200 to remove metal ions and COD content from wastewater.
[0055] like Figures 2-3 It is known that the storage component 200 is fixedly installed on the top and front end of the purification box 110 for storing the medicine.
[0056] The storage assembly 200 includes a storage chamber 210 and a discharge pipe 220 for material conveying. The discharge pipe 220 is installed at the output end of the bottom of the storage chamber 210. A material inlet hole 211 is provided at the top of the front end of the storage chamber 210 for material injection. The top of the storage chamber 210 is movably connected to a cover by a hinge. To facilitate the movement of the cover, its end is provided with an anti-slip protrusion. The valve body 221 can be a metering valve for precise material feeding.
[0057] The bottom of the storage chamber 210 is connected to a connecting frame 212 for supporting it. The bottom of the connecting frame 212 is connected to a bottom base 213. The bottom base 213 is installed above the purification box 110. A valve body 221 is installed on the surface of the discharge pipe 220 for opening and closing the pipe cavity.
[0058] Specifically, there are multiple sets of storage components 200, which are respectively set on the top of the neutralization box 111, the reaction box 112, and the flocculation box 113, and on the left, middle and right sides of the front end of the side plate 130, while the two vertical storage components 200 are used in conjunction with each other.
[0059] like Figures 2-5 It is known that the feeding assembly 300 is located at the bottom of the purification box 110 and is used for the addition of multiple drugs. The feeding assembly 300 includes a drive component 310 for power drive and a lead screw component 320 for transmission. The output end of the lead screw component 320 is provided with a feeding pump body 330 for conveying drugs. Through the drive component 310 and the lead screw component 320, the position of the feeding pump body 330 can be adjusted so that it can drive the conveying pipe to move to one end of the corresponding storage component 200 for drug addition.
[0060] The lead screw 320 includes a mounting frame 321, which is installed at the bottom of the inner cavity of the lower bearing housing 120. The front end of the mounting frame 321 is provided with an opening and closing groove 322. The lead screw 320 is movably installed in the inner cavity of the mounting frame 321 through a bearing. A threaded screw plate 323 is threaded on the surface of the lead screw 320. One end of the threaded screw plate 323 passes through the opening and closing groove 322 and is connected to the support 331. The bottom of the delivery pump body 330 is provided with a support 331, which enhances the stability of the delivery pump body 330 and facilitates the movement of the delivery pump body 330. The support 331 is slidably set in the inner cavity of the slide rail 121 through a pulley to provide auxiliary support for the delivery pump body 330.
[0061] Specifically, the output end of the drive unit 310 is connected to one end of the lead screw 320, enabling transmission of the lead screw 320. The lead screw 320 is preferably a reciprocating lead screw. Thus, when the drive unit 310 is working, it can drive the feed pump body 330 to move under the cooperation of the lead screw 320 and the screw plate 323. Under the action of the pulleys on the slide rail 121 and the support 331, the stability of the feed pump body 330 during movement is increased, thereby facilitating the adjustment of the position of the feed pump body 330 among the multiple material storage components 200.
[0062] like Figure 2 and Figure 4 As shown, a distance sensor is provided at the material storage assembly 200 on the side plate 130 for use when the feed pipe 332 travels, to control the travel position of the feed pipe 332 and ensure that it is precisely at the bottom of the discharge pipe 220.
[0063] Preferably, the top of the feed pipe 332 is connected to a feed hopper for auxiliary material receiving;
[0064] like Figure 4 It can be seen that the output end of the induced draft pump body 330 is connected to the feed pipe body 332 through a flange seal, and the input end of the induced draft pump body 330 is connected to the feed pipe body 340. The induced draft pump body 330 is preferably a diaphragm pump.
[0065] The feed pipe 332 and the feeding pipe 340 respectively penetrate the inner cavity of the sliding groove 122 and slide in contact with it. To enhance the connection stability, the inner cavity of the sliding groove 122 is provided with a sliding plate, which is connected to the surface of the feed pipe 332 and the feeding pipe 340.
[0066] like Figure 2 It can be seen that the bottom of the front end of the side plate 130 is provided with a through groove that has the same shape and effect as the sliding groove 122, which is used to support the feed tube 332 and avoid limiting the movement of the feed tube 332.
[0067] like Figure 1 and Figure 2 As shown, the top of the purification box 110 is equipped with a guardrail, and one end of the feeding pipe 340 is equipped with a monitoring component 350. The monitoring component 350 includes a sliding plate 352, which is sleeved on the surface of the feeding pipe 340. Its top and bottom are slidably disposed on the top of the purification box 110 through a sliding joint 353. The sliding joint 353 and the guardrail on the top of the purification box 110 are in sliding contact to assist in supporting the feeding pipe 340. A connecting seat 351 is installed on the surface of the monitoring component 350, and its other end is connected to the sliding plate 352.
[0068] Specifically, the monitoring component 350 is an intelligent monitoring camera used to observe the wastewater treatment status inside the neutralization tank 111, reaction tank 112 and flocculation tank 113 of the purification box 110. In cooperation with the feeding pipe 340, the monitoring component 350 can be driven to move laterally around the purification box 110 through the drive component 310 and the lead screw component 320, thereby effectively observing the wastewater treatment status inside the purification box 110.
[0069] like Figure 2 and Figure 4 As shown, an auxiliary support rod 360 is provided at the end of the feeding pipe 340. There are multiple auxiliary support rods 360, which are connected by a connecting plate 362. A sliding sleeve 361 is slidably sleeved on the surface of the auxiliary support rod 360. One end of the sliding sleeve 361 is connected to the feeding pipe 340 to increase the stability of the feeding pipe 340 when it moves. The bottom of the connecting plate 362 is connected to the end of the guardrail on the purification box 110.
[0070] like Figure 4 As shown, the other end of the feeding tube 340 is a telescopic tube, which can force one end of the feeding tube 340 into the material inlet hole 211. When moving, the other end of the feeding tube 340 is stretched and disengaged from the material inlet hole 211, thereby effectively conveying material into its interior.
[0071] Preferably, magnetic strips are embedded at the junction of the material inlet hole 211 and the feeding tube 340 to increase the stability of the feeding tube 340 in conveying materials to the top storage chamber 210 of the purification box 110.
[0072] Desulfurization wastewater can be fed into the triple-tank assembly 100. The wastewater is purified by the structural characteristics of the purification tank 110. During desulfurization, the storage assembly 200 can add chemicals to the purification tank 110 to accelerate the treatment of desulfurization wastewater and remove impurities such as heavy metals from the wastewater. When the triple-tank assembly 100 and the storage assembly 200 are used together for purification, the feeding assembly 300 can feed chemicals into the storage assembly 200, reducing manual feeding and increasing feeding efficiency.
[0073] like Figures 2-6 It is known that the sewage discharge component 400 is set at the sludge output end at the bottom of the purification box 110 for sludge discharge; the sewage discharge component 400 includes a sewage discharge main pipe 410 and a feeding auger 420. The sewage discharge main pipe 410 is set in the inner cavity of the lower bearing box 120. The end of the sewage discharge main pipe 410 is connected to a plurality of connecting pipe fittings 411. The top of the plurality of connecting pipe fittings 411 is respectively connected to the bottom of the neutralization box 111, the reaction box 112 and the flocculation box 113 on the purification box 110. The sewage discharge main pipe 410 and the connecting pipe fittings 411 cooperate for sludge discharge. The feeding auger 420 is set in the inner cavity of the sewage discharge main pipe 410.
[0074] like Figure 4 and Figure 6 As shown, the output end of the drive unit 310 is fitted with an active gear disk 311, which is used to provide auxiliary transmission for the components on the sewage discharge assembly 400. One end of the feeding auger 420 is connected to a coupling 430. The surface of the coupling 430 is fitted with a driven gear disk 431. The driven gear disk 431 and the active gear disk 311 mesh with each other. Through the drive unit 310 and under the transmission cooperation of the active gear disk 311 and the driven gear disk 431, the feeding auger 420 is driven to rotate, thereby effectively discharging the sludge from the neutralization box 111, the reaction box 112 and the flocculation box 113 through the sewage discharge main pipe 410 quickly.
[0075] like Figures 2-7 It is known that the stirring assembly 500 is set in the inner cavity of the purification box 110 and is used for mixing the reagents and discharging sludge. The stirring assembly 500 includes a stirring motor 510. The output end of the stirring motor 510 is connected to a transmission rod 520. The surface and bottom of the transmission rod 520 are respectively connected to stirring blades 530 and scraper plates 540. When the stirring motor 510 is working, it can drive the stirring blades 530 and scraper plates 540 to rotate through the transmission rod 520, thereby quickly mixing the wastewater and reagents in the neutralization box 111, reaction box 112 and flocculation box 113, and accelerating the wastewater purification treatment. The scraper plates 540 can scrape off the sludge attached in the neutralization box 111, reaction box 112 and flocculation box 113, so that the sludge falls into the sewage discharge pipe 410 and is quickly discharged.
[0076] like Figure 7 As shown, a support frame 511 is provided at the bottom of the stirring motor 510. The support frame 511 is mounted on the purification box 110. A mounting base 512 is installed on the top of the support frame 511 to provide auxiliary support for the stirring motor 510 and the storage chamber 210 located on top of the purification box 110.
[0077] like Figures 1-7 As shown, the desulfurization wastewater treatment method according to an embodiment of this application includes:
[0078] S1. Control the valve body 221 to open and close, and put the corresponding reagents, such as sodium hydroxide and high-efficiency wastewater removal agent, into the neutralization tank 111 through the corresponding storage chamber 210. Operate the stirring motor 510 to control the transmission rod body 520 and stirring blade body 530 to rotate, and stir the wastewater inside the neutralization tank 111 to react. The effluent enters the reaction tank 112.
[0079] The wastewater from desulfurization is a supersaturated solution of gypsum, which contains a large number of metal ions. Various metal ions can easily react in the desulfurization system, damaging the material of the system or causing precipitation and scaling. Therefore, adding sodium hydroxide to the neutralization tank can increase the pH value of the wastewater, causing the metal ions to precipitate in the alkaline solution. On the other hand, it can also reduce the saturation of the solution.
[0080] S2. Control the opening and closing of the corresponding valve body 221, and put the corresponding reagents, such as organic sulfur and high-efficiency wastewater removal agent, into the reaction tank 112 through the corresponding storage chamber 210. Operate the stirring motor 510 to control the transmission rod body 520 and stirring blade body 530 to stir and react the wastewater inside the neutralization tank 111. The effluent enters the flocculation tank 113.
[0081] Since neutralization tank 111 cannot remove all metal ions, sodium hydroxide can only precipitate hydroxide metal ions. At this time, organic sulfur needs to be added to reaction tank 112 to generate sulfide precipitates of the remaining heavy metal ions, thereby further removing metal ions from the wastewater.
[0082] S3. Control the opening and closing of the corresponding valve body 221, and add the corresponding agents, such as flocculant, polyferric sulfate and high-efficiency wastewater removal agent, into the flocculation box 113 through the corresponding storage chamber 210. Operate the stirring motor 510 to control the rotation of the transmission rod body 520 and the stirring blade body 530 to stir and react the wastewater inside the neutralization box 111.
[0083] It can aggregate the fine and dispersed metal ions in wastewater into large particles, thereby accelerating the entire sedimentation process. During this process, oxygen ion polyacrylamide, a coagulant aid, is added to the outlet of flocculation box 113 to further improve the flocculation speed of the precipitate. The purified product is then discharged through the pipe.
[0084] S4. When inspecting the wastewater inside the purification chamber 110, the drive component 310 can be controlled to move the lead screw component 320 and adjust the position of the feeding pipe 340, thereby assisting in adjusting the movement of the monitoring component 350 to inspect the wastewater inside the purification chamber 110.
[0085] S5. When feeding material to the top of the purification box 110, the control drive 310 drives the lead screw 320, so that the screw plate 323 drives the feeding pump body 330 to slide laterally along the opening and closing groove 322, so that the feed pipe 332 moves to the bottom of the corresponding discharge pipe 220 on the side plate 130. At the same time, the feeding pipe 340 is inserted into the corresponding feeding through hole 211 to prepare for receiving material.
[0086] S6. During material conveying, the feeding pump body 330 is used to control the valve body 221 on the discharge pipe body 220 at the corresponding side plate 130 position to open, so that the material stored inside the storage chamber 210 is sucked into the corresponding storage chamber 210 above the purification box 110 through the feeding pipe body 332, the feeding pump body 330 and the feeding pipe body 340, thus completing the feeding.
[0087] S7. When the sewage in the purification box 110 is discharged, the driving stirring motor 510 drives the scraper plate 540 to rotate, and scrapes the sludge in the inner cavity of the neutralization box 111, reaction box 112 and flocculation box 113 into the sewage discharge pipe 410. The driving drive 310 drives the coupling 430 and the feeding auger 420 to rotate through the active gear plate 311 and the driven gear plate 431, thereby quickly discharging the sludge in the sewage discharge pipe 410 and completing the sludge cleaning work.
[0088] Specifically, the working principle of this desulfurization wastewater treatment system and method is as follows: Control valve 221 to open and close, add the corresponding reagent to neutralization tank 111, operate stirring motor 510 to control transmission rod 520 and stirring blade 530 to rotate, stirring the wastewater inside neutralization tank 111, and the effluent enters reaction tank 112; subsequently, add the corresponding reagent to reaction tank 112, and stir the wastewater inside neutralization tank 111, the effluent enters flocculation tank 113; add the corresponding reagent to flocculation tank 113, and stir the wastewater inside neutralization tank 111, thereby purifying the wastewater.
[0089] When feeding material into the top of the purification box 110, the control drive 310 drives the lead screw 320 to move the feed pipe 332 to the bottom of the corresponding discharge pipe 220 on the side plate 130. At the same time, the feeding pipe 340 is inserted into the corresponding feed hole 211 to prepare for receiving material. Meanwhile, the drive 310 drives the lead screw 320 to move and adjust the position of the feeding pipe 340, which can assist in adjusting the movement of the monitoring component 350.
[0090] During material conveying, the feeding pump body 330 is used to control the valve body 221 on the discharge pipe body 220 at the corresponding side plate 130 position to open, so that the material stored inside the storage chamber 210 is sucked into the corresponding storage chamber 210 above the purification box 110 through the feed pipe body 332, the feeding pump body 330 and the feed pipe body 340, thus completing the feeding.
[0091] When the sewage in the purification box 110 is discharged, the driving stirring motor 510 drives the scraper plate 540 to rotate, and scrapes the sludge in the neutralization box 111, reaction box 112 and flocculation box 113 into the sewage discharge pipe 410. The driving component 310 drives the coupling component 430 and the feeding auger 420 to rotate through the active gear plate 311 and the driven gear plate 431, thereby quickly discharging the sludge in the sewage discharge pipe 410 and completing the sludge cleaning work.
