Abstract
Description
Technical Field
[0001] This invention relates to the field of wastewater treatment technology, and more specifically, to a desulfurization wastewater treatment device. Background Technology
[0002] Desulfurization wastewater treatment equipment is a specialized treatment device for high-salt, high-hardness wastewater generated by wet desulfurization processes in industrial fields such as coal-fired power plants and steel smelting. Its core function is to remove pollutants such as sulfides, sulfates, calcium and magnesium ions and heavy metals from the wastewater, so as to achieve the wastewater discharge in compliance with standards or reuse.
[0003] In existing technologies, filtered wastewater is typically introduced into a treatment tank through a feed pipe. Lime water or sodium carbonate solution is sprayed into the treatment tank to neutralize and precipitate sulfides and sulfates. The sulfides and sulfates combine to form calcium sulfide, while sodium carbonate adjusts the pH to assist in the precipitation of sulfides by metal ions. This ensures that the lime water or sodium carbonate solution is fully mixed with the wastewater, making the reaction more thorough. Ultimately, the sulfides and sulfates in the wastewater are effectively removed, and then the wastewater is transported to the next process through a discharge pipe.
[0004] In practical applications of existing technologies, calcium and magnesium ions in wastewater are difficult to completely remove during the wastewater desulfurization process, resulting in a significant amount of residual calcium and magnesium ions remaining after treatment. These residual calcium and magnesium ions may not only interfere with the removal of other pollutants in subsequent treatment processes, but may also prevent the treated wastewater from consistently meeting the predetermined reuse or discharge requirements, thus affecting the reliability and efficiency of the overall treatment system.
[0005] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a desulfurization wastewater treatment device. Summary of the Invention
[0006] The purpose of this invention is to provide a desulfurization wastewater treatment device to solve the above-mentioned problems.
[0007] To achieve the above objectives, an embodiment of the present invention provides the following technical solution:
[0008] A desulfurization wastewater treatment device includes a treatment tank, a desulfurization component, a calcium and magnesium removal control component, and a calcium and magnesium concentration adaptive flow channel adjustment component. A connecting block is fixedly connected to the upper surface of the treatment tank. The desulfurization component is installed inside the treatment tank. The calcium and magnesium removal control component is installed inside the treatment tank. The calcium and magnesium removal control component is installed inside the calcium and magnesium concentration adaptive flow channel adjustment component.
[0009] The desulfurization component includes a drive motor fixedly connected to the lower surface of the connecting block, a drive rod mounted on the output shaft end of the drive motor, and a rotating ball fixedly connected to one end of the drive rod; the calcium and magnesium removal control component includes a connecting rod fixedly connected to the outer surface of the rotating ball, a rotating disk fixedly connected to one end of the connecting rod, and multiple calcium and magnesium removal channels opened inside the rotating disk; the calcium and magnesium concentration adaptive flow channel adjustment component includes multiple auxiliary balls fixedly connected inside the calcium and magnesium removal channels, an elastic bladder installed inside the auxiliary balls, and a flow guide ring installed in the inner cavity of the calcium and magnesium removal channels.
[0010] As a further improvement of the present invention, the desulfurization component includes a lime chamber fixedly connected inside the rotating sphere. The outer surface of the lime chamber is provided with a plurality of holes. The interior of the lime chamber is filled with lime slurry blocks to enhance the removal effect of sulfides and heavy metal ions. The holes allow wastewater to enter the lime chamber, thereby improving the utilization rate of the reagent and preventing excessively high local concentrations.
[0011] As a further improvement of the present invention, the desulfurization component also includes an annular water pipe fixedly connected to the inside of the treatment tank by a support block. Multiple nozzles are installed obliquely on the outer surface of the annular water pipe, and a hose is connected to the outer surface of the annular water pipe. The liquid medicine is evenly delivered to the nozzles through the annular water pipe to realize the atomization spraying of the medicine. The hose is connected to an external storage tank to ensure a stable supply of liquid medicine and improve the mixing efficiency.
[0012] As a further improvement of the present invention, a filling chamber is installed on the outer surface of the elastic capsule, and multiple holes are opened on the outer surface of the filling chamber. The filling chamber is filled with polyphosphate blocks. Wastewater is introduced through the holes and reacts with the polyphosphate blocks in the filling chamber to form a dual-path removal mechanism of "main channel + secondary channel".
[0013] As a further improvement of the present invention, the calcium and magnesium removal control component includes a polyphosphate chamber installed inside the rotating disk, a pumping pipe installed inside the polyphosphate chamber, a pump installed on the outer surface of the pumping pipe, and a plurality of branch pipes fixedly connected to one end of the pumping pipe, so that the agent is delivered to the branch pipes through the pumping pipe.
[0014] As a further improvement of the present invention, the branch pipe is connected to the atomizing spray gun through the connecting pipe. The atomizing spray gun is inserted into the inner cavity of the calcium and magnesium removal channel. The medicine is transported to the atomizing spray gun through the connecting pipe. The atomizing spray gun converts it into micron-sized water mist. The water mist is sprayed into the calcium and magnesium removal channel to improve the contact area and reaction efficiency with calcium and magnesium ions.
[0015] As a further improvement of the present invention, the calcium and magnesium concentration adaptive flow channel adjustment component includes multiple elastic rods fixedly connected inside the flow guide ring. A magnetic block is fixedly connected inside the elastic rod near the top wall of the inner cavity of the flow guide ring. An electromagnet is fixedly connected inside the treatment tank. The electromagnet and the magnetic block are magnetically connected. The elastic rod supports the flow guide ring and transmits displacement force when the magnetic field changes, thereby driving the flow guide ring to reset. The magnetic block and the electromagnet form a non-contact driving structure. The main controller adjusts the current direction and intensity of the electromagnet to change the magnetic force (attraction or repulsion) between it and the magnetic block, thereby realizing the automatic adjustment of the flow guide ring.
[0016] As a further improvement of the present invention, the guide ring is inverted trumpet shape, and a plurality of metal springs are fixedly connected to the outer surface of the auxiliary ball. An elastic bladder is connected to the bottom of the guide ring, and a delivery pipe is connected inside the elastic bladder. The inverted trumpet-shaped guide ring optimizes the water flow distribution and generates a vortex, while the metal springs enhance the disturbance effect.
[0017] As a further improvement of the present invention, one end of the delivery pipe is fixedly connected to an adjustment pipe, which is connected to the inner cavity of the elastic bladder to realize gas transmission and pressure regulation, thereby dynamically adjusting the flow area of the calcium and magnesium removal channel.
[0018] As a further improvement of the present invention, the bottom of the treatment tank is fixedly connected with multiple support legs, the outer surface of the treatment tank is fixedly connected with a feed pipe, the outer surface of the treatment tank is installed with a discharge pipe, and the outer surfaces of the feed pipe and the discharge pipe are both covered with cover plates, so as to realize the input of wastewater and the output of purified water through the feed pipe and the discharge pipe.
[0019] Compared with the prior art, the advantages of the present invention are: (1) The desulfurization wastewater to be treated is introduced into the treatment tank through the feed pipe, and the lime water and sodium carbonate mixture is transported to the ring water pipe through the hose. The nozzle sprays the medicine solution evenly into the treatment tank. At the same time, the rotating ball is driven by the drive motor and drive rod to disperse the sprayed medicine solution, making it finer and more evenly distributed, improving the utilization rate of the mixture. Under the action of centrifugal force, the wastewater and medicine solution are fully collided and mixed, removing sulfides and heavy metal ions, and completing the preliminary purification; (2) The wastewater enters the lime chamber through the holes on the surface of the rotating ball and comes into contact with the lime slurry block, and enters the lime chamber through the holes on the surface of the rotating ball. (2) Remove sulfides and heavy metal ions from wastewater in one step to avoid excessive local concentration, improve the reaction efficiency of the solution and reduce waste; (3) After preliminary treatment, the wastewater enters the calcium and magnesium removal channel. The pump draws the polyphosphate agent from the polyphosphate chamber to the atomizing spray gun. The atomizing spray gun converts the agent into a mist and sprays it evenly into the calcium and magnesium removal channel to increase the contact area between the agent and the wastewater. At the same time, the sprayed mist agent will impact the calcium and magnesium removal channel to further refine it, accelerate the complexation reaction rate of calcium and magnesium ions, effectively reduce the total hardness of the water and prevent scale formation in subsequent equipment; (4) The concentration of calcium and magnesium ions in the wastewater is detected in real time by the monitoring sensor. When the sensor detects that the calcium and magnesium ion concentration is too high, the main controller starts the electromagnet to generate a magnetic field with the same polarity as the magnetic block. This causes the magnetic block to be repulsed, which drives the guide ring and elastic rod to move downward, squeezing the elastic bladder to release gas, pushing the auxiliary ball to expand, reducing the effective flow area of the calcium and magnesium removal channel, extending the wastewater retention time, and improving the reaction efficiency. This allows for real-time monitoring and automatic adjustment, dynamically changing the size of the calcium and magnesium removal channel to adapt to water quality fluctuations and enhance adaptability. (5) When the calcium and magnesium ion concentration returns to the normal range, the main controller adjusts the direction of the electromagnet current to generate a magnetic field with the opposite polarity to the magnetic block. The magnetic block resets under the attraction force, driving the guide ring. The elastic rod returns to its original state, the elastic bladder contracts, the volume of the auxiliary ball decreases, the calcium and magnesium removal channel returns to normal flow capacity, the wastewater forms a swirling effect through the guide ring, making the water flow distribution more uniform, avoiding excessive local concentration or dead zone formation, thereby achieving adaptive recovery of the size of the calcium and magnesium removal channel; (6) through the hole two on the surface of the auxiliary ball, some wastewater can enter the filling chamber through this hole two, and react with the solid polyphosphate block in it again to chemically complex, further reducing the concentration of residual calcium and magnesium ions in the wastewater, thereby forming a dual-path removal mechanism of "main channel + secondary channel", and at the same time, the metal shrapnel on the surface of the auxiliary ball can play an impact disturbance function on the wastewater.

[0034] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0035] Example 1:
[0036] Please see Figures 1-9 A desulfurization wastewater treatment device includes a treatment tank 1, a desulfurization component 2, a calcium and magnesium removal control component 3, and a calcium and magnesium concentration adaptive flow channel adjustment component 4. A connecting block 104 is fixedly connected to the upper surface of the treatment tank 1, and multiple support legs 101 are fixedly connected to the bottom of the treatment tank 1. The support legs 101 support the treatment tank 1. An inlet pipe 102 is fixedly connected to the outer surface of the treatment tank 1, and an outlet pipe 103 is installed on the outer surface of the treatment tank 1. Both the inlet pipe 102 and the outlet pipe 103 are covered with cover plates. The inlet pipe 102 ensures the input of wastewater, and the outlet pipe 103 can discharge the purified wastewater into the interior of the treatment tank 1.
[0037] The desulfurization assembly 2 is installed inside the treatment tank 1. The desulfurization assembly 2 includes a drive motor 201 fixedly connected to the lower surface of the connecting block 104. A drive rod 202 is installed at the output shaft end of the drive motor 201. A rotating ball 203 is fixedly connected to one end of the drive rod 202. The desulfurization assembly 2 includes a lime chamber 204 fixedly connected inside the rotating ball 203. Multiple holes 207 are opened on the outer surface of the lime chamber 204. The lime chamber 204 is filled with lime slurry. Some wastewater enters the lime chamber 204 through the holes 207 and reacts with the lime slurry to promote the further purification of the wastewater. The desulfurization assembly 2 also includes an annular water pipe 205 fixedly connected to the inside of the treatment tank 1 by a support block. Multiple nozzles 206 are installed obliquely on the outer surface of the annular water pipe 205. A flexible hose 208 is connected to the outer surface of the annular water pipe 205.
[0038] Furthermore, one end of the hose 208 is connected to an external storage tank containing a mixture of lime water and sodium carbonate, and the mixture is transported to the nozzle 206 via a ring water pipe 205. The nozzle 206 sprays the solution into the inner cavity of the treatment tank 1. The drive motor 201 is started to drive the drive rod 202 to rotate. When the drive rod 202 rotates, it drives the rotating ball 203 to rotate. At this time, the solution is transported to the nozzle 206 through the hose 208 and the ring water pipe 205. The nozzle 206 sprays the solution evenly into the interior of the treatment tank 1. During the rotation, the rotating ball 203 disperses the sprayed solution. At the same time, after the wastewater enters the treatment tank 1 from the feed pipe 102, it is dispersed under the centrifugal force generated by the rotating ball 203 and fully collides and mixes with the solution, completing the initial purification of the wastewater.
[0039] Example 2:
[0040] Reference Figures 1-9 This is the second novel embodiment of the present invention, which is based on the previous embodiment. The calcium and magnesium removal control component 3 is installed inside the treatment tank 1.
[0041] The calcium and magnesium removal control component 3 includes a connecting rod 301 fixedly connected to the outer surface of the rotating ball 203. One end of the connecting rod 301 is fixedly connected to a rotating disk 302. The rotating disk 302 has multiple calcium and magnesium removal channels 303 inside. The calcium and magnesium removal control component 3 includes a polyphosphate chamber 304 installed inside the rotating disk 302. The polyphosphate chamber 304 is filled with polyphosphate brine. The polyphosphate brine is used to remove calcium and magnesium ions from wastewater. Depending on actual needs, the polyphosphate brine can be replaced with other agents that can effectively remove calcium and magnesium ions, such as sodium hexametaphosphate or sodium citrate.
[0042] The polyphosphate chamber 304 is equipped with a pumping pipe 305. A pump 308 is installed on the outer surface of the pumping pipe 305. One end of the pumping pipe 305 is fixedly connected to multiple branch pipes 309. The branch pipes 309 are connected to the atomizing spray gun 307 through the connecting pipe 306. The atomizing spray gun 307 is inserted into the inner cavity of the calcium and magnesium removal channel 303 so as to spray the agent on the wastewater flowing in the calcium and magnesium removal channel 303, so that the agent removes the calcium and magnesium ions in the wastewater.
[0043] The atomizing spray gun 307 employs a contraction-expansion nozzle structure. After the liquid is accelerated at the throat, it undergoes cavitation due to a sudden pressure drop when ejected from the expansion section, creating a velocity difference with the wastewater in the channel. The high-speed jet impacts the water flow, tearing it into 50-100μm droplets. Even in water, it overcomes viscous constraints to achieve atomization. Simultaneously, the rotation of the rotating disk 302 causes the wastewater in the calcium and magnesium removal channel 303 to form a swirling flow. The shear force of the water flow further assists in droplet dispersion, preventing re-aggregation after atomization and ensuring sufficient contact area with the wastewater. The nozzle of the atomizing spray gun 307 is oriented at a 30°-45° angle to the water flow direction in the calcium and magnesium removal channel 303, rather than directly facing the water flow. This reduces the direct impact of the high-speed water flow on the nozzle, preventing the droplets from being "dispersed" by the water flow and resulting in excessively high local concentrations. It also allows the droplets to diffuse along the swirling flow direction, evenly distributing them across the entire channel cross-section. A precision filter and sealing joint can be added as needed to ensure the operational stability of the atomizing spray gun 307.
[0044] The calcium and magnesium removal control component 3 is internally equipped with a calcium and magnesium concentration adaptive flow channel adjustment component 4. The calcium and magnesium concentration adaptive flow channel adjustment component 4 includes multiple auxiliary balls 408 fixedly connected inside the calcium and magnesium removal channel 303. An elastic bladder 401 is installed inside the auxiliary balls 408. A flow guide ring 404 is installed inside the cavity of the calcium and magnesium removal channel 303. The calcium and magnesium concentration adaptive flow channel adjustment component 4 includes multiple elastic rods 4041 fixedly connected inside the flow guide ring 404. The elastic rods 4041 have good elasticity and reset performance, and can generate corresponding deformation displacement when the external magnetic field changes, and automatically return to the initial state after the magnetic field is removed.
[0045] A magnetic block 6 is fixedly connected to the inside of the elastic rod 4041 near the top wall of the inner cavity of the guide ring 404. An electromagnet 5 is fixedly connected to the inside of the treatment tank 1. The electromagnet 5 and the magnetic block 6 are magnetically connected. A monitoring sensor, such as an ion selective electrode sensor (e.g., Thermo Scientific Orion 9302BN model), is installed on the upper surface of the guide ring 404. Dedicated calcium ion selective electrodes and magnesium ion selective electrodes are selected for calcium and magnesium ion respectively. The concentration is reflected by directly measuring the activity of calcium and magnesium ions in the wastewater. The measurement accuracy is high and the response speed is fast. The data is fed back to the main controller based on the STM32 series ARM Cortex-M microcontroller. The main controller controls the electromagnet 5 to generate a change in magnetic field, which drives the magnetic block 6 to move the guide ring 404, squeezes the second elastic bladder 405 to release gas into the first elastic bladder 401, and pushes the auxiliary ball 408 to change its volume. This dynamically adjusts the flow area of the calcium and magnesium removal channel 303, ensuring stable effluent quality and optimizing treatment efficiency, preventing equipment scaling and fluctuations in treatment effect.
[0046] The guide ring 404 is inverted trumpet shape, and multiple metal springs 402 are fixedly connected to the outer surface of the auxiliary ball 408. The inverted trumpet-shaped guide ring 404 guides the wastewater to form a swirling distribution, and the metal springs 402 enhance the turbulent mixing effect, ensuring efficient and stable removal of calcium and magnesium ions under different water quality conditions. The bottom of the guide ring 404 is connected to an elastic bladder 405, and the interior of the elastic bladder 405 is connected to a conveying pipe 403. One end of the conveying pipe 403 is fixedly connected to a regulating pipe 406, which is connected to the inner cavity of the elastic bladder 401. The interior of the elastic bladder 405 is filled with gas, and gas transmission is achieved between the elastic bladder 401 and the elastic bladder 405 through the conveying pipe 403 and the regulating pipe 406. Thus, under the linkage of the magnetic block 6 and the electromagnet 5, the effective flow area of the calcium and magnesium removal channel 303 is dynamically adjusted to optimize the wastewater treatment effect.
[0047] Furthermore, the pump 308 is activated to deliver the polyphosphate agent in the polyphosphate chamber 304 through the delivery pipe 305 and connecting pipe 306 to multiple atomizing spray guns 307. The atomizing spray guns 307 convert the agent into water mist and spray it into the calcium and magnesium removal channel 303. The water mist is further dispersed by the impact generated when the monitoring sensor detects that the calcium and magnesium ion concentration is too high. When the monitoring sensor detects that the calcium and magnesium ion concentration is too high, the electromagnet 5 is activated to generate the same magnetic field as the magnetic block 6, causing the magnetic block 6 to move the guide ring 404 and the elastic rod 4041 downward, and squeeze the elastic bladder 405, releasing gas through the delivery pipe 403 and regulating pipe 4. 06 is conveyed to the elastic bladder 401, causing the elastic bladder 401 to expand and increase the volume of the auxiliary ball 408, thereby reducing the effective flow area of the calcium and magnesium removal channel 303; when the calcium and magnesium ion content in the wastewater is within the preset value, the electromagnet 5 is activated to generate a magnetic field opposite to that of the magnetic block 6, causing the magnetic block 6 to move the guide ring 404, and the guide ring 404 is reset by the elastic rod 4041, and the channel restores its normal flow capacity. When the wastewater forms a vortex through the guide ring 404, the water flow distribution is more uniform, avoiding excessively high local concentrations or dead zones. The uniformly distributed wastewater then enters the calcium and magnesium removal channel 303.
[0048] Working principle: In use, the feed pipe 102 is usually connected to the wastewater pipe to ensure that the wastewater enters the treatment tank 1 at a stable flow rate. Then, the power supply of the treatment tank 1 is stably connected to the external socket, and it is confirmed that the drive motor 201 and the electromagnet 5 are in normal standby state. The pump 308 communicates with the main controller through the wireless module. At the same time, one end of the hose 208 is connected to the external lime water and sodium carbonate mixture storage tank (or a chemical solution that can eliminate sulfur-containing substances such as sulfides and sulfates in wastewater) to ensure that the chemical solution is delivered to the annular water pipe 205 through the hose 208, and then delivered to the nozzle 206 through the annular water pipe 205, so that the nozzle 206 sprays the chemical solution into the inner cavity of the treatment tank 1.
[0049] Subsequently, the power supply and controller of the drive motor 201 and the monitoring sensor are started, causing the drive motor 201 to drive the drive rod 202 to rotate. When the drive rod 202 rotates, it will drive the rotating ball 203 to rotate. At this time, the liquid medicine enters the annular water pipe 205 through the hose 208 and is evenly sprayed into the treatment tank 1 by multiple nozzles 206. During the rotation, the rotating ball 203 disperses the sprayed liquid medicine, making the medicine finer and more evenly distributed. At the same time, after the wastewater enters the treatment tank 1 from the feed pipe 102, it is dispersed under the centrifugal force generated by the rotating ball 203 and fully collides and mixes with the liquid medicine, thereby removing sulfides, sulfates and heavy metal ions from the wastewater. The wastewater comes into contact with the lime slurry blocks filled in the lime chamber 204 through multiple holes 207 on the surface of the rotating ball 203, further completing the preliminary purification of the wastewater.
[0050] After preliminary treatment, the wastewater continues to flow downwards and enters the calcium and magnesium removal control component 3 and the calcium and magnesium concentration adaptive flow channel adjustment component 4 below. At this time, the rotating ball 203 drives the rotating disk 302 to rotate synchronously through the connecting rod 301, forming a secondary stirring effect and improving the mixing efficiency of wastewater and chemical solution.
[0051] Simultaneously, the power supply and controller of the pump 308 are activated, causing the pump 308 to transport the polyphosphate agent (or other agents capable of eliminating calcium and magnesium ions) in the polyphosphate chamber 304 through the pumping pipe 305 and connecting pipe 306 to multiple atomizing spray guns 307. The atomizing spray guns 307 convert the agent into water mist and spray it into the calcium and magnesium removal channel 303. The spraying into the calcium and magnesium removal channel 303 creates an impact, further dispersing the water mist and increasing the contact area between the agent and the wastewater. Furthermore, when the rotating disk 302 rotates, the rotation of the rotating disk 302 also enhances the mixing disturbance in the calcium and magnesium removal channel 303, causing the agent to react with the calcium and magnesium ions in the wastewater to achieve the purpose of removing calcium and magnesium compounds, thereby effectively reducing the total hardness of the water and preventing scaling in subsequent equipment.
[0052] When the monitoring sensor installed on the guide ring 404 detects the concentration of calcium and magnesium ions in the wastewater entering the calcium and magnesium removal channel 303 in real time, and the monitoring sensor detects that the concentration of calcium and magnesium ions is too high, the electromagnet 5 is activated to generate the same magnetic field as the magnetic block 6. This causes the magnetic block 6 to move the guide ring 404 and the elastic rod 4041 downwards, squeezing the second elastic bladder 405. The gas is released and transported to the first elastic bladder 401 through the conveying pipe 403 and the regulating pipe 406, causing the first elastic bladder 401 to expand and increase in size. This pushes the auxiliary ball 408 to increase in volume, thereby reducing the effective flow area of the calcium and magnesium removal channel 303 (e.g., Figure 8 As shown in the figure, this extends the residence time of wastewater in the channel and improves the removal effect of the reagent on calcium and magnesium ions.
[0053] When the monitoring sensor detects in real time that the calcium and magnesium ion content in the desulfurization wastewater is within the preset value, the electromagnet 5 is activated to generate a magnetic field opposite to that of the magnetic block 6, causing the magnetic block 6 to move the guide ring 404, and the guide ring 404 is reset by the elastic rod 4041 (e.g., Figure 6 As shown), the elastic bladder 401 returns to its original shape, the auxiliary ball 408 contracts, and the channel restores its normal flow capacity. When the wastewater forms a vortex through the guide ring 404, the water flow distribution becomes more uniform, avoiding excessively high local concentrations or dead zones. The uniformly distributed wastewater then enters the calcium and magnesium removal channel 303.
[0054] In addition, the metal shrapnel 402 on the surface of the auxiliary ball 408 can impact the wastewater, further reducing the calcium and magnesium ions in the wastewater. The wastewater can enter the filling chamber 407 through the hole 2 and undergo a chemical complexation reaction with the polyphosphate block in the filling chamber 407, further reducing the concentration of residual calcium and magnesium ions in the wastewater, forming a dual-path removal mechanism of "main channel + secondary channel".
