Description

Technical Field

[0001] The invention belongs to the technical field of wastewater treatment, in particular to an industrial wastewater treatment device, and more specifically to a platinum-palladium treatment device for industrial wastewater. Background Art

[0002] Industrial wastewater often contains highly toxic heavy metal ions, such as Cr 6+ The common treatment method is to reduce the high-valent heavy metal ions into low-toxic or non-toxic forms (such as Cr) by catalytic reduction reaction, using precious metal catalysts such as platinum and palladium and reducing agents (such as hydrogen and formic acid). 3+ etc.), thereby achieving the purpose of purifying wastewater. Platinum and palladium are widely used in the field of industrial wastewater treatment due to their excellent catalytic properties, chemical stability and corrosion resistance.

[0003] Existing industrial wastewater treatment devices usually adopt a fixed reaction box structure, which is mainly composed of a wastewater input system, a catalyst addition system, a reaction system and an effluent treatment system. Existing wastewater treatment devices for high-priced toxic heavy metal ions usually adopt a method of directly adding catalysts into wastewater during use. However, since the direct feeding position is relatively fixed and the mixing effect is poor, the catalyst is usually added to the reaction box through a fixed feeding port, resulting in uneven distribution in the wastewater, easy deposition at the bottom of the reaction box, and difficulty in sufficient contact with the wastewater, resulting in insufficient reaction and poor catalytic effect, thereby reducing the reaction efficiency. At the same time, since the catalyst cannot be effectively dispersed and the concentration of reactants in some areas is insufficient, the heavy metal reduction is incomplete. At the same time, unreacted catalysts and reducing agents are discharged with the wastewater, resulting in waste of resources and secondary pollution risks, and some catalysts fail to play their catalytic role.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figures 1 to 12 As shown, the present invention provides an industrial wastewater treatment device, including a working box 1, a control terminal 11 fixedly arranged outside the working box 1, and a support plate 12 fixedly installed on both sides symmetrically inside the working box 1, and also includes: The reaction mechanism 2 is located at the upper part of the working box 1 and is used to treat the wastewater; A recovery mechanism 3, which is located at the bottom of the reaction mechanism 2 and is used to recover the treated platinum and palladium; The reaction mechanism 2 includes a reaction box 21 fixedly arranged on the top of the support plate 12, a water outlet arranged at the bottom of the reaction box 21, two movable grooves 211 opened on both sides of the reaction box 21, a mixing component 22 arranged inside the reaction box 21, and a feeding component 23 located inside the reaction box 21, wherein the mixing component 22 is used to fully stir the wastewater, the catalyst and the reducing agent, and the feeding component 23 is used to uniformly add the catalyst and the reducing agent; The feeding assembly 23 includes a quantitative box 231 , a feeding pipe 232 arranged at the bottom of the quantitative box 231 , and a driving component 233 arranged inside the reaction box 21 for driving the quantitative box 231 and the feeding pipe 232 to move along the inside of the reaction box 21 .

[0023] The above scheme is adopted: by using the reaction mechanism 2 to achieve a full reaction of the wastewater and the catalyst, specifically by introducing the wastewater feed port into the interior of the reaction box 21, pouring the platinum palladium particles as a catalyst into the quantitative box 231, under the catalytic action of the platinum palladium catalyst, the heavy metal ions such as Cr in the wastewater 6+The platinum palladium catalyst in the quantitative box 231 is discharged through the discharge pipe 232 during the treatment process.

The feed tube 232 passes through the U-shaped groove 2313 and slides inside the U-shaped groove 2313. A telescopic rod 234 is fixedly provided on the side wall of the sleeve rod 2321.

The stirring rod 221 is provided with multiple groups of stirring blades.

[0025] The above scheme is adopted: through the coordinated use of the reaction box 21, the mixing component 22 and the discharge component 23, the platinum-palladium catalyst is uniformly introduced into the wastewater. Specifically, the adjusting motor 2332 is used to drive the bidirectional screw rod 2331 to rotate, so that the connecting frame 2312 slides along the bidirectional screw rod 2331 under the limiting action of the moving block 2311 and the moving groove 211. During the sliding process, the sleeve rod 2321 cooperates with the telescopic rod 234 under the limiting action of the corrugated groove 2334, driving the sleeve rod 2321 to move along the corrugated groove 2334 on the mounting plate 2333, and synchronously drives the bottom discharge pipe 232 to move along the U-shaped groove 2313 during the movement. The bellows 2322 has telescopic ductility and can be automatically adjusted during the movement of the connecting frame 2312 without affecting its movement. The bellows adjustment of the feeding pipe 232 can be achieved to discharge the platinum-palladium catalyst inside the quantitative box 231 into the reaction box 21 by corrugating movement, so that the platinum-palladium catalyst inside falls evenly into the reaction box 21, increasing the contact range with the wastewater. During the feeding process, the rotating motor 222 is synchronously started to drive the stirring rod 221 to rotate, so that the platinum-palladium catalyst falling into the reaction box 21 is fully mixed with the wastewater, and the heavy metal ions in the wastewater are converted into low-toxic or non-toxic forms, thereby improving the catalytic reaction efficiency and the wastewater treatment efficiency.

[0026] like Figures 2 to 3 As shown, the recovery mechanism 3 includes a magnetic roller 31 located directly below the water outlet, a control motor 32 fixedly arranged at one end of the magnetic roller 31, a guide box 33 located at the bottom of the magnetic roller 31, a scraper 34 fixedly arranged on one side of the top of the guide box 33, and a circulation component 35 arranged at the bottom of the guide box 33, the scraper 34 is used to scrape the platinum and palladium on the magnetic roller 31, and the circulation component 35 is used to recover substances in the wastewater; Both ends of the magnetic roller 31 are rotatably connected to the symmetrical sides of the support plate 12 and the working box 1, the control motor 32 is fixedly connected to the outer wall of the working box 1, and the two sides of the guide box 33 are fixedly connected to the side of the support plate 12 close to each other. The guide box 33 is trapezoidal in shape, and the bottom is sequentially provided with a first discharge port 331 and a second discharge port 332. A guide plate 333 is fixedly provided on the inclined surface of the guide box 33 on the side close to the second discharge port 332, and a third discharge port 334 is provided at the top position of the guide box 33 close to the guide plate 333. The scraper 34 is fixedly connected to the top of the side of the guide box 33 close to the guide plate 333. The scraper 34 is triangular in shape and is tightly attached to the magnetic roller 31. The scraper 34 is made of rubber.

[0027] The above scheme is adopted: the wastewater to be treated is poured into the interior of the reaction mechanism 2 along the top of the working box 1, and then platinum palladium particles are poured into the reaction mechanism 2 as a catalyst. Under the catalytic action of the platinum palladium catalyst, heavy metal ions such as Cr in the wastewater are 6+The wastewater undergoes a reduction reaction with a reducing agent such as hydrogen, formic acid, etc., converting it into a low-toxic or non-toxic form, and then uses the recovery mechanism 3 for discharge and recovery. At the same time, it is also convenient to recover platinum and palladium simultaneously, thereby improving the utilization rate. Specifically, the wastewater after the reaction treatment enters the interior of the guide box 33, and passes through the magnetic roller 31 to adhere the platinum and palladium particles in the treated water to the magnetic roller 31. The water flows through the first discharge port 331 into the bottom circulation component 35 for detection and discharge. At the same time, the control motor 32 is started to drive the magnetic roller 31 to rotate. During the rotation, the magnetic roller 31 will drive the platinum and palladium particles on the surface to pass through the scraper 34, and the scraper 34 will scrape them off. The scraped platinum and palladium particles may be mixed with this part of the water source, which falls on the guide plate 333 by gravity. The water flow containing the platinum and palladium particles is discharged into the circulation component 35 along the second discharge port 332 and the guide plate 333 through the guide plate 333 for circulation treatment, thereby completing the entire operation.

[0028] like Figure 6 As shown, the circulation assembly 35 includes a recovery box 351 fixedly arranged at the bottom of the guide box 33, a drainage pipe 352 fixedly installed on the side of the recovery box 351 and penetrating the support plate 12 and the side wall of the working box 1, a recovery pipe 353 fixedly arranged on the side of the recovery box 351, and a circulation pipe 354 fixedly installed on the side of the recovery box 351 away from the scraper 34; Two partitions 3511 are fixedly arranged inside the recovery box 351, and the two partitions 3511 divide the recovery box 351 into three sections, namely, recovery zone 1, recovery zone 2 and recovery zone 3, wherein recovery zone 1 is located at the bottom of the guide plate 333, recovery zone 2 is located at the bottom of the second discharge port 332, and recovery zone 3 is located at the bottom of the first discharge port 331. Recovery zone 1 and recovery zone 2 are used to recover platinum and palladium, and recovery zone 3 is used to detect the treated wastewater. A PH sensor 3512 is fixedly arranged inside the recovery zone 3, and the PH sensor 3512 is electrically connected to the control terminal 11; The first solenoid valve 3521, the second solenoid valve 3531 and the third solenoid valve 3541 are fixedly arranged on the drain pipe 352, the recovery pipe 353 and the circulation pipe 354 respectively. The first solenoid valve 3521, the second solenoid valve 3531 and the third solenoid valve 3541 are all electrically connected to the control terminal 11. A guide pipe 3532 is fixedly arranged on the side of the recovery area 2. The guide pipe 3532 is connected to the recovery pipe 353 and a filter 3533 is fixedly arranged at the connection between the two. A pump body is fixedly arranged inside the reaction box 21. The recovery pipe 353 and the circulation pipe 354 on the side away from the recovery box 351 both penetrate the reaction box 21 and are connected to the pump body inside the reaction box 21.

[0029] The above scheme is adopted: the recycling component 35 is used to realize the recovery of platinum-palladium particles and the detection and circulation treatment of wastewater, thereby improving the wastewater treatment effect and the recovery rate of platinum-palladium. The specific process is as follows: the treated water flow is introduced into the recovery area three through the guide box 33, and the water flow containing platinum-palladium elements is introduced into the recovery area two and the recovery area three through the second discharge port 332 and the guide plate 333 respectively. The pH sensor 3512 in the recovery area three detects the pH value of the treated water flow, and transmits the detection result to the control terminal 11, and compares it with the preset threshold value (usually pH value 6-9) in the storage module. If the detection result exceeds the threshold range, indicating that the treatment is unqualified, the control terminal 11 will start the third solenoid valve 3541, and cooperate with the pump body to re-introduce the unqualified wastewater through the circulation pipe 354 into the reaction mechanism 2 for secondary treatment; if the detection is qualified, the control terminal 11 opens the first solenoid valve 3521 to discharge the qualified water flow through the drain pipe 352; In addition, when the water flow and particles containing platinum and palladium elements enter the recovery area two and the recovery area three, the control terminal 11 can start the second solenoid valve 3531 to transport the water flow containing platinum and palladium elements to the filter 3533 through the recovery pipe 353 and the guide pipe 3532. After the activated carbon in the filter 3533 filters the water flow, the filtered water flow is reintroduced into the reaction mechanism 2 along the recovery pipe 353 for reuse through the pump body. Through the above process, not only the effective treatment and detection of wastewater is achieved, but also the efficient recovery of platinum and palladium elements is completed, achieving the dual effects of resource recycling and environmental protection treatment.

[0030] The working principle and use process of the present invention are as follows: when using the device, the driving component 233 can be used to first move the quantitative box 231 to a side away from the feed port. At this time, the wastewater to be treated is introduced into the interior of the reaction box 21 along the feed port. After the introduction is completed, the driving component 233 is used to move the reaction box 21 to the feed port, and the platinum-palladium catalyst is introduced into the quantitative box 231. During the introduction, the dosage of the platinum-palladium catalyst can be adjusted according to the amount of wastewater to be treated. After the feeding is completed, the driving component 233 is used to drive the sleeve rod 2321 to move along the corrugated groove 2334 on the mounting plate 2333. During this process, the quantitative box 231 slides in the moving groove 211, and the discharge pipe 232 slides in the U-shaped groove 2313, so that the platinum-palladium catalyst in the quantitative box 231 is discharged along the bottom corrugation of the discharge pipe 232, so that the platinum-palladium catalyst is evenly distributed in the reaction box 21, and the mixing component 22 is used to realize the platinum-palladium The catalyst and wastewater are fully mixed and reacted to achieve the treatment of the wastewater. The treated wastewater and the platinum-palladium catalyst enter the guide box 33 along the discharge port at the bottom of the reaction box 21. When passing through the magnetic roller 31, the platinum-palladium particles are adsorbed by the magnetic roller 31. The magnetic roller 31 drives the adsorbed platinum-palladium particles to move synchronously during rotation, and scrapes them off through the scraper 34, so that they fall into the recovery area two and the recovery area three under the action of gravity for collection. The water flow without platinum-palladium particles directly enters the recovery area three through the first discharge port 331. The PH sensor 3512 in the recovery area three detects the treated water. If the water quality is qualified, it is discharged through the drain pipe 352; if it is unqualified, the water flow is re-introduced into the reaction box 21 through the circulation pipe 354 for secondary treatment. At the same time, the platinum-palladium elements in the recovery area two and the recovery area three re-enter the reaction box 21 through the recovery pipe 353, realizing the recycling of resources, thereby significantly improving the resource utilization rate.
