Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to an industrial wastewater treatment device and method with multiple separation functions. Background Technology

[0002] Wastewater includes industrial wastewater, industrial sewage, and cooling water. It refers to the wastewater and waste liquid generated during industrial production processes. It contains industrial raw materials, intermediate products, by-products, and pollutants generated during production that are lost with the water. Industrial wastewater is diverse and complex in composition. For example, wastewater from the electrolytic salt industry contains mercury, wastewater from the heavy metal smelting industry contains lead, cadmium, and other metals, wastewater from the electroplating industry contains cyanide and chromium, wastewater from the petroleum refining industry contains phenols, and wastewater from the pesticide manufacturing industry contains various pesticides.

[0003] This study addresses the challenges posed by toxic components in highly polluted industrial wastewater, including their ability to inhibit microbial activity, difficulty in decomposition, significant environmental hazards, high COD (Chemical Oxygen Demand) concentrations, and complex composition. Through theoretical analysis and numerical simulations, key components of the treatment system are optimized and improved, ultimately enhancing the efficiency and effectiveness of industrial wastewater treatment.

[0004] Meanwhile, existing industrial wastewater treatment equipment cannot effectively collect particulate matter after treating wastewater, making it inconvenient for subsequent unified treatment. Furthermore, existing wastewater treatment equipment does not specifically separate wastewater and then treat the separated products accordingly. This lack of specificity in wastewater treatment easily leads to poor wastewater treatment results. Summary of the Invention

[0010] Furthermore, the evaporation assembly includes an evaporation chamber, which is installed above the transmission pipe. The transmission pipe has an exhaust port located inside the evaporation chamber. An induction coil is installed outside the transmission pipe, which can heat the transmission pipe. A condensate film and a water collection chamber are provided inside the evaporation chamber. Multiple sets of guide rods are installed on the condensate film and the water collection chamber.

[0011] Furthermore, the flocculation component includes a flocculation tank, a stirring motor installed above the flocculation tank, a stirring assembly installed inside the flocculation tank, the output end of the stirring motor connected to the stirring assembly, a flocculation zone provided at the bottom of the flocculation tank, the flocculation zone connected to the slag discharge tank, and a recovery tank provided on the side of the flocculation tank, the recovery tank being connected to the water collection tank and the flocculation tank respectively.

[0012] Furthermore, the inner wall of the flocculation tank is provided with multiple sets of serpentine grooves, the stirring assembly includes a transmission rod, the transmission rod is provided with multiple sets of stirring rods and multiple sets of levers, the stirring rods are connected to the transmission rod through universal joints, the other end of the stirring rod is equipped with a slider, the slider cooperates with the serpentine grooves, the two ends of the stirring rod are respectively connected to the slider and the transmission rod through bearings, the stirring rod includes two sets of sub-rods, the two sets of sub-rods are connected by universal joints, and the total length of the two sets of sub-rods is greater than the radius of the flocculation tank.

[0013] Furthermore, the controller is installed on the side of the main body of the wastewater treatment equipment. The controller is connected to the main body of the wastewater treatment equipment and has a control panel. The control panel can indirectly control the main body of the wastewater treatment equipment.

[0014] To achieve the above objectives, the present invention provides the following technical solution: an industrial wastewater treatment method with multiple separation functions, the method being applicable to an industrial wastewater treatment device with multiple separation functions, and the method comprising the following steps:

[0015] S1: Separation component for wastewater separation;

[0016] S2: Slag discharge tank for drying and recycling of sand and gravel;

[0017] S3: The evaporation unit heats and sterilizes the separated liquid;

[0018] S4. The flocculation component performs secondary treatment on the separated liquid.

[0019] Furthermore, S1 includes S11: the separation component separates industrial wastewater into slurry and a small amount of impurities in liquid, the slurry enters the slag discharge tank, and the liquid enters the flocculation component through the evaporation component.

[0020] S2 includes S21: the slag discharge tank throws sand and gravel onto the conveyor belt through the bumping component, and the heating component dries the sand and gravel on the conveyor belt.

[0021] S3 includes S31: After the evaporation component heats the separated liquid, the generated steam enters the water collection tank to disinfect the liquid while recovering a small amount of liquid.

[0022] S4 includes S41: After the liquid enters the flocculation tank, a certain amount of flocculant is added to separate the impurities in the liquid from the liquid.

[0023] S42: The separated liquid enters the recovery tank, and the separated flocculated impurities enter the slag discharge pool.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. When in use, this device can separate particulate matter, oil and other substances in wastewater through the separation component, and then treat them accordingly. The particulate matter is treated uniformly, while the separated liquid is heated and disinfected. Then, the remaining fine particles are subjected to secondary flocculation treatment, so that the final wastewater is free of particulate matter, which is convenient for recycling or secondary disinfection.

[0026] 2. When in use, the slag discharge tank can recover the sand and gravel particles inside. Then, depending on the different particles, they can be used accordingly. In specific use, the separation component can discharge the slurry into the slag discharge tank, and then the agitation component stirs in the slag discharge tank. Each stirring will carry up the particles in the tank, and some particles and liquid will be thrown onto the conveyor belt under the inertial swing.

[0027] 3. When in use, the evaporation component can heat-treat the separated liquid, sterilizing it by heating. Specifically, when industrial wastewater after passing through the separation component is discharged from the transmission pipe to the flocculation component, it will pass through the evaporation component. The induction coil of the evaporation component can heat the transmission pipe, and the liquid passing through the transmission pipe will be indirectly heated. After the liquid is heated to a high temperature, it will generate a certain amount of steam. When passing through the evaporation box, the steam will be discharged through the exhaust port. Then the steam will be adsorbed on the condensate film. Because the condensate film is limited by the guide rod, the steam on the condensate film will form water droplets and enter the water collection tank through the guide rod. Then the water collection tank will discharge the collected liquid into the recovery tank.

[0028] 4. When in use, the stirring assembly can agitate the liquid in the flocculation tank, accelerating the reaction between the liquid and the flocculant. Specifically, the stirring assembly operates under the drive of a stirring motor. The motor drives a transmission rod to rotate, which in turn drives the stirring rod and the agitator plate. The agitator plate agitates the water flow, increasing its speed. The other end of the stirring rod is connected to a serpentine chute via a slider. As the stirring rod rotates, it moves along the serpentine chute. Because the stirring rod consists of two sets of sub-rods connected by a universal joint, and the total length of the two sets of sub-rods exceeds the radius of the flocculation tank, the stirring rod rotates in a curved shape within the flocculation tank. One end of the stirring rod is fixed to the transmission rod, causing it to oscillate repeatedly as it moves along the serpentine chute, thus more thoroughly agitating the liquid in the flocculation tank.

[0039] The technical solutions of the embodiments 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example: Figures 1-9 As shown, the present invention provides an industrial wastewater treatment device with multiple separation functions, including a wastewater treatment device body 1 and a controller 9. The wastewater treatment device body 1 includes a separation component 2 and a flocculation component 3. A slag discharge tank 4 is installed at the bottom of the separation component 2. The separation component 2 cooperates with the flocculation component 3 and the slag discharge tank 4 respectively. The flocculation component 3 cooperates with the slag discharge tank 4. The separation component 2 can separate oil and sand from the wastewater. The flocculation component 3 can flocculate the residual particles in the wastewater. The slag discharge tank 4 can collect sand.

[0041] In operation, the device first supplies industrial wastewater to the separation component 2, where it separates the wastewater from the slurry. The separated slurry is then discharged into the slag discharge tank 4, while the separated liquid is supplied to the flocculation component 3. Before entering the flocculation component 3, the liquid passes through the evaporation component 7, which heats the liquid to a high temperature, removing harmful substances. This heating also generates water vapor, which is only released when passing through the evaporation component 7. The evaporation component 7 collects the water vapor, which is then directly transferred to the recovery tank 11 for further processing as needed. The liquid in tank 11 is processed, while most of the liquid enters the flocculation component 3. The flocculation component 3 can perform secondary treatment on the filtered liquid. The specific working process is as follows: an appropriate amount of flocculant is added to the flocculation tank 31 according to the total amount of liquid, and then the stirring component 8 is started to accelerate the reaction between the flocculant and the liquid. After the reaction with the reagent, the liquid will have flocculent impurities and will be deposited in the flocculation zone 32. The relatively clean liquid will be discharged into the recovery tank 11. After the clean liquid is discharged, a small portion of the liquid will carry the flocculent impurities into the slag discharge tank 4, where the particulate matter will be recovered. Thus, when the device is in use, it can recover recyclable materials from industrial wastewater and disinfect some harmful substances.

[0042] like Figures 1-3 As shown in this embodiment, specifically, an installation frame 41 and a conveyor belt 42 are installed above the slag discharge tank 4. A heating component 5 is installed between the conveyor belts 42, and a separation component 2 is installed between the installation frames 41. A bumping component 6 is installed inside the slag discharge tank 4. The bumping component 6 includes a bumping platform 63 and multiple sets of bumping motors 61. The multiple sets of bumping motors 61 are equidistantly installed outside the slag discharge tank 4. Multiple sets of S-shaped transmission plates 62 are installed inside the slag discharge tank 4. One end of the multiple sets of S-shaped transmission plates 62 is connected to the bumping motor 61, and the other end of the S-shaped transmission plate 62 is connected to the bumping platform 63. The bumping platform 63 is provided with filter holes. The bumping component 6 cooperates with the conveyor belt 42.

[0043] When the slag discharge tank 4 of the device is in use, it can recycle the sand and gravel particles inside it. Then, it can be used according to the different particles. In specific use, the separation component 2 can discharge the slurry into the slag discharge tank 4. Then, the agitation component 6 stirs in the slag discharge tank 4. Each stirring will bring up the particles in the tank. Some particles and liquid will be thrown onto the conveyor belt 42 under the inertial swing.

[0044] Its working principle is as follows: the external bumping motor 61 drives the S-shaped transmission plate 62 to rotate. Because there are multiple sets of S-shaped transmission plates 62, the movement trajectory of the bumping platform 63 is limited. Each time the bumping platform 63 moves to the highest position, it will move downward under the drive of the S-shaped transmission plate 62. The sand and gravel on the bumping platform 63 will be thrown onto the conveyor belt 42 by inertia. Then the heating component 5 will heat the sand and gravel particles on the conveyor belt 42 so that they can be discharged in a dry state. Due to the structure of the conveyor belt 42, most of the liquid will return to the slag discharge pool 4 with the curvature of the conveyor belt 42. The particulate matter will be intercepted by the irregular lint on the conveyor belt 42, thereby reducing the burden on the heating component 5.

[0045] like Figure 2 As shown, in this embodiment, specifically, the heating component 5 includes multiple sets of heating wires 51, which are equidistantly installed between the conveyor belts 42. The heating wires 51 can dry the sand and gravel on the conveyor belts 42.

[0046] When in use, the heating component 5 of the device can heat and dry the sand and gravel on the conveyor belt 42, thereby facilitating the storage and handling of sand and other particulate matter during recycling. Specifically, when there is sand or particulate matter on the conveyor belt 42, the controller 9 will energize the heating wire 51, so that the heating wire 51 can generate heat, thereby heating the sand and gravel particles on the conveyor belt 42, thus facilitating the subsequent recycling of sand and gravel and other particulate matter.

[0047] like Figures 1-2 and Figure 4 As shown in this embodiment, specifically, the separation component 2 includes multiple sets of hydrocyclones 21, which are equidistantly installed between the mounting brackets 41. The bottom of the hydrocyclone 21 is provided with a sandblasting port 212, and the top of the hydrocyclone 21 is provided with a water inlet 211 and an overflow port 213. The overflow port 213 cooperates with the flocculation component 3, and a transmission pipe 22 is connected between the overflow port 213 and the flocculation component 3. An evaporation component 7 is provided on the transmission pipe 22, and the liquid separated by the evaporation component 7 is evaporated and disinfected.

[0048] When in use, the separation component 2 of this device can separate particulate matter and liquid in industrial wastewater. In specific use, the wastewater pipeline needs to be connected to the inlet 211 of the hydrocyclone 21. When the industrial wastewater enters the hydrocyclone 21, the two-phase mixture to be separated enters the hydrocyclone 21 tangentially from the periphery of the hydrocyclone 21 under a certain pressure, generating a strong three-dimensional elliptical strong rotational shear turbulent motion. Due to the size difference between coarse and fine particles, they are subjected to different magnitudes of centrifugal force, centripetal buoyancy, and fluid drag. Under the action of centrifugal sedimentation, most of the coarse particles are discharged through the sandblasting port 212 at the bottom of the hydrocyclone 21, while most of the fine particles are discharged through the overflow pipe, thereby achieving the purpose of separation and classification.

[0049] like Figure 1 , Figure 6 and Figure 7 As shown, in this embodiment, specifically, the evaporation assembly 7 includes an evaporation box 71, which is installed above the transmission pipe 22. The transmission pipe 22 is located inside the evaporation box 71 and has an exhaust port 221. An induction coil 72 is installed outside the transmission pipe 22, which can heat the transmission pipe 22. A condensate film 711 and a water collection tank 712 are provided inside the evaporation box 71. Multiple sets of guide rods 713 are installed on the condensate film 711 and the water collection tank 712. The guide rods 713 are installed at an angle between the condensate film 711 and the water collection tank 712. The guide rods 713 are inclined downward from one end of the condensate film 711 to the top of the water collection tank 712.

[0050] When in use, the evaporation component 7 of this device can perform heat treatment on the separated liquid, thereby heating and disinfecting the separated liquid. Specifically, when the industrial wastewater after passing through the separation component 2 is discharged from the transmission pipe 22 to the flocculation component 3, it will pass through the evaporation component 7. The induction coil 72 of the evaporation component 7 can heat the transmission pipe 22, and the liquid passing through the transmission pipe 22 will be indirectly heated. After the liquid is heated to a high temperature, a certain amount of steam will be generated. When passing through the evaporation box 71, the steam will be discharged through the exhaust port 221. Then the steam will be adsorbed on the condensate film 711. Since the condensate film 711 is limited by the guide rod 713, the steam on the condensate film 711 will form water droplets and enter the water collection tank 712 through the guide rod 713. Then the water collection tank 712 will discharge the collected liquid into the recovery tank 11.

[0051] like Figure 5 As shown in this embodiment, specifically, the flocculation component 3 includes a flocculation tank 31, a stirring motor is installed on the top of the flocculation tank 31, a stirring component 8 is installed inside the flocculation tank 31, the output end of the stirring motor is connected to the stirring component 8, a flocculation zone 32 is provided at the bottom of the flocculation tank 31, the flocculation zone 32 is connected to the slag discharge tank 4, and a recovery tank 11 is provided on the side of the flocculation tank 31, the recovery tank 11 is connected to the water collection tank 712 and the flocculation tank 31 respectively;

[0052] When in use, the flocculation component 3 of this device can flocculate the separated liquid. This is because there are still a small number of particles in the liquid separated by the separation component 2, only the particles are relatively small. The flocculation component 3 can flocculate these small particles. In specific use, the operator needs to add a certain amount of flocculant according to the total amount of liquid in the flocculation tank 31, and then start the stirring motor. The stirring motor can drive the stirring component 8, thereby accelerating the reaction between the liquid and the reagent. The flocculated particles will slowly settle into the flocculation zone 32, and the flocculated particles in the flocculation zone 32 will be discharged into the slag discharge tank 4 for particulate matter recovery.

[0053] like Figure 5 and Figure 9 As shown in this embodiment, specifically, the inner wall of the flocculation tank 31 has multiple sets of serpentine grooves 311. The stirring assembly 8 includes a transmission rod 81, on which multiple sets of stirring rods 82 and multiple sets of levers 84 are provided. The stirring rods 82 are connected to the transmission rod 81 through universal joints. The other end of the stirring rod 82 is equipped with a slider 83, which cooperates with the serpentine grooves 311. The two ends of the stirring rod 82 are respectively connected to the slider 83 and the transmission rod 81 through bearings. The stirring rod 82 includes two sets of sub-rods 821, which are connected by universal joints. The total length of the two sets of sub-rods 821 is greater than the radius of the flocculation tank 31.

[0054] When in use, the stirring assembly 8 of this device can stir the liquid in the flocculation tank 31, accelerating the reaction between the liquid and the flocculant. Specifically, the stirring assembly 8 operates under the drive of a stirring motor. The stirring motor drives the transmission rod 81 to rotate, which in turn drives the stirring rod 82 and the deflector plate 84 on it to rotate. The deflector plate 84 can agitate the water flow, increasing its speed. However, the other end of the stirring rod 82 is connected to the serpentine chute 311 via a slider 83, thus the stirring rod 82 rotates... When in motion, the stirring rod 82 moves along with the serpentine chute 311. Since the stirring rod 82 consists of two sets of sub-rods 821 connected by a universal joint, and the total length of the two sets of sub-rods 821 is greater than the radius of the flocculation tank 31, the stirring rod 82 will rotate in a curved shape inside the flocculation tank 31. One end of the stirring rod 82 is fixed on the transmission rod 81. As the stirring rod 82 moves along with the serpentine chute 311, it will fluctuate repeatedly, thereby more fully stirring the liquid in the flocculation tank 31.

[0055] like Figure 1 As shown in this embodiment, specifically, a controller 9 is installed on the side of the wastewater treatment equipment body 1. The controller 9 is connected to the wastewater treatment equipment body 1. The controller 9 is equipped with a control panel 91, which can indirectly control the wastewater treatment equipment body 1.

[0056] When in use, the device can control the entire wastewater treatment equipment 1 through the controller 9, and the control panel on the controller 9 can be easily operated by the workers, so the workers can indirectly control the entire equipment through the control panel.

[0057] like Figures 1-9 As shown, this invention provides a method for treating industrial wastewater with multiple separation functions. The method is applicable to an industrial wastewater treatment device with multiple separation functions and includes the following steps:

[0058] S1: Separation component for wastewater separation;

[0059] S2: Slag discharge tank for drying and recycling of sand and gravel;

[0060] S3: The evaporation unit heats and sterilizes the separated liquid;

[0061] S4. The flocculation component performs secondary treatment on the separated liquid.

[0062] like Figures 1-9 As shown, in this embodiment, specifically, S1 includes S11: the separation component separates industrial wastewater into slurry and a small amount of impurities in liquid, the slurry enters the slag discharge tank, and the liquid enters the flocculation component through the evaporation component.

[0063] S2 includes S21: The slag discharge tank throws sand and gravel onto the conveyor belt through the bumping component, and the heating component dries the sand and gravel on the conveyor belt.

[0064] S3 includes S31: After the evaporation component heats the separated liquid, the generated steam enters the water collection tank to disinfect the liquid while recovering a small amount of liquid.

[0065] S4 includes S41: After the liquid enters the flocculation tank, a certain amount of flocculant is added to separate the impurities in the liquid from the liquid.

[0066] S42: The separated liquid enters the recovery tank, and the separated flocculated impurities enter the slag discharge pool.

[0067] Working Principle: In operation, industrial wastewater is first supplied to separation component 2. Separation component 2 separates the wastewater and slurry. The separated slurry is then discharged into slag discharge tank 4, while the separated liquid is supplied to flocculation component 3. Before entering flocculation component 3, the liquid also passes through evaporation component 7. Evaporation component 7 heats the liquid at high temperatures, removing harmful substances. This heating generates water vapor, which is only released when passing through evaporation component 7. The evaporation component 7 collects the water vapor, which is then directly transferred to recovery tank 11 for further processing as needed. The liquid in the recovery tank 11 is processed, and most of the liquid enters the flocculation component 3. The flocculation component 3 can perform secondary treatment on the filtered liquid. The specific working process is as follows: an appropriate amount of flocculant is added to the flocculation tank 31 according to the total amount of liquid, and then the stirring component 8 is started to accelerate the reaction between the flocculant and the liquid. After the reaction with the reagent, the liquid will have flocculent impurities and will be deposited in the flocculation zone 32. The relatively clean liquid will be discharged into the recovery tank 11. After the clean liquid is discharged, a small portion of the liquid will carry the flocculent impurities into the slag discharge tank 4, where the particulate matter will be recovered. Thus, when the device is in use, it can recover recyclable materials from industrial wastewater and disinfect some harmful substances.

[0068] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
