Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to industrial acidic wastewater treatment and recovery equipment. Background Art

[0002] Industrial acidic wastewater is a common type of wastewater generated in the industrial production process. Its characteristic is that it contains high concentrations of acidic substances, such as sulfuric acid, hydrochloric acid, etc. If this wastewater is discharged directly into the environment without treatment, it will cause serious damage to the soil, water bodies and ecosystems. Therefore, the treatment of industrial acidic wastewater is particularly important.

[0003] After searching, the Chinese invention patent with publication number "CN111732166A" discloses "an industrial wastewater treatment equipment". The application drives the lifting drive gear to rotate through the lifting drive motor, and then the lifting drive gear drives the annular rack and the rotating threaded sleeve to rotate, so that the jacking support screw drives the forward branch electromagnet and the two reverse branch electromagnets to enter and exit the wastewater connecting pipe through the entrance and exit passage. When entering, the current switch box transmits current to the forward branch electromagnet and the two reverse branch electromagnets, so that the forward branch electromagnet and the two reverse branch electromagnets obtain a magnetic field, and the metal waste slag in the industrial wastewater flowing through the forward branch electromagnet and the two reverse branch electromagnets in the wastewater connecting pipe is adsorbed, so that the metal waste slag is tightly adsorbed on the forward branch electromagnet and the two reverse branch electromagnets, thereby avoiding the metal waste slag in the industrial wastewater from being unable to be collected and mixed into the industrial wastewater sludge, causing pollution to the environment at the sludge discharge site, and also avoiding the metal waste slag from infiltrating into other equipment in the sewage during the later treatment process, causing other equipment to be stuck or damaged.

[0004] In addition, the Chinese invention patent with publication number "CN108249487A" discloses "a recycling and treatment system for treating acidic industrial wastewater". This application adds fixed grooves, elastic blocks and other mechanisms to automatically discharge the sludge when the sludge in the equipment reaches the set value, avoiding blockage of equipment pipelines due to failure to clean up the sludge in time, ensuring thorough filtration of wastewater, and preventing pollution and harm to human health and the environment when the filtered water is used.

[0005] However, when recycling sulfuric acid wastewater, since sulfuric acid wastewater is acidic, any one of the electrolysis method and the neutralization method or a combination of the two will be used for treatment when the industrial wastewater equipment is used for treatment. However, when using the electrolysis method, since the electrodes will continuously react with the electrolyte, it will cause corrosion and wear of the electrode materials. In addition, if the neutralization reaction is carried out simultaneously, the pressure of gas and foam, as well as the heat and stress generated during the electrolysis process, may cause the sealing of the electrolytic cell to be damaged, resulting in leakage.

DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the present invention application to clearly and completely describe the technical solution in the present invention application. Obviously, the described application is only a part of the present invention application, not the whole application. Based on the application in the present invention, all other applications obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] Before understanding the application proposed by this application, it should be clear that the industrial acidic wastewater treated by this application is sulfuric acid wastewater. It should be clear that sulfuric acid wastewater contains sulfate ions (SO4 ²- ), hydrogen ion (H + ) and other possible heavy metal ions and organic matter, such as: heavy metal ions include: lead (Pb ²+ ), cadmium (Cd ²+ ), chromium (Cr ³+ / Cr 6+ ), organic matter includes: phenol, formaldehyde, etc.

[0050] However, when recycling sulfuric acid wastewater, since sulfuric acid wastewater is acidic, electrolysis is used for treatment when treating industrial wastewater equipment. However, when using electrolysis, the electrodes will continuously react with the electrolyte, which will cause corrosion and wear of the electrode materials. Therefore, during actual operation, the present application performs a neutralization treatment on the sulfuric acid wastewater before treating the sulfuric acid wastewater by electrolysis, thereby effectively reducing the corrosion and wear problems generated during the electrolysis process. It should be added that the pH value of the sulfuric acid wastewater is adjusted to near neutrality through neutralization treatment, which not only reduces the loss of electrode materials, but also reduces the risk of damage to the sealing of the electrolytic cell. In addition, the wastewater after neutralization treatment is more suitable for subsequent electrolysis treatment, thereby improving the overall treatment efficiency.

[0051] Specifically, refer to Figure 1-Figure 12 It can be seen that in the present application, the device includes: a first pipe fitting 2 , a second pipe fitting 1 and a third pipe fitting 3 .

[0052] It should be clear that in the present application, the first pipe fitting 2 is used to receive industrial acidic wastewater, the second pipe fitting 1 is used to connect to the first pipe fitting 2 and treat the industrial acidic wastewater based on neutralization and electrolysis, and the third pipe fitting 3 is used to connect to the second pipe fitting 1 and to discharge the gas discharged from the second pipe fitting 1 based on neutralization and electrolysis.

[0053] It should be further added that, in the present application, the first pipe fitting 2 gradually opens the connection with the second pipe fitting 1 as the pressure of the industrial acidic wastewater in the first pipe fitting 2 increases. There is a time frequency for the first pipe fitting 2 to transport the industrial acidic wastewater to the second pipe fitting 1. In each time frequency segment, the second pipe fitting 1 receives the same amount of industrial acidic wastewater from the first pipe fitting 2, and the second pipe fitting 1 is charged with an equal amount of neutralizing liquid as the industrial acidic wastewater in each time frequency segment, and electrolysis is performed after the neutralizing liquid and the industrial acidic wastewater react. During the period when two adjacent time frequency segments are adjacent, the third pipe fitting 3 discharges the treated gas and the second pipe fitting 1 discharges the treated liquid.

[0054] It should be noted that in the present application, the treatment liquid is a strong alkaline solution, specifically a sodium hydroxide solution, with a concentration of 2% to 10%, which is used to ensure that the treatment liquid has sufficient alkalinity to neutralize the acidic substances. In addition, it should be noted that in actual applications, sulfuric acid (H2SO4) in sulfuric acid wastewater develops a neutralization reaction with sodium hydroxide (NaOH) to generate sodium sulfate (Na2SO4) and water (H2O). The chemical equation of the reaction is: According to the chemical equation, the neutralization method can reduce the acidity of sulfuric acid wastewater. In addition, it should be added that in the actual operation of the present application, the treatment gas discharged by the third pipe 3 is carbon dioxide (CO2) and oxygen (O2). These gases are by-products produced during the electrolysis process. Specifically, during the electrolysis process, sulfate ions (SO4 ²- ) and hydrogen ions (H + ) reacts under the action of electrodes to generate sulfuric acid (H2SO4) and water (H2O), while releasing oxygen, and heavy metal ions are deposited on the electrodes during the electrolysis process, thereby achieving removal. The combined use of neutralization treatment and electrolysis not only improves the treatment efficiency, but also achieves effective removal of harmful substances in sulfuric acid wastewater. In addition, in addition to generating sulfuric acid and water, carbon dioxide is also generated during the electrolysis process. This is because some water molecules are decomposed during the electrolysis process. The entire treatment process not only reduces the acidity of sulfuric acid wastewater, but also removes heavy metal ions therein, thereby achieving the purpose of purifying wastewater.

[0055] refer to Fig. 9 and Fig.10 It can be seen that in this application, the first condition 2 includes:

[0056] The electronic diversion valve tube 201 has a flange ring installed at one end thereof for connecting to industrial acid wastewater discharge equipment, and a filter ring 210 is installed inside the electronic diversion valve tube 201 .

[0057] It should be clear that when the first pipe fitting 2 is actually used, the flange ring installed in the electronic diversion valve tube 201 can be tightly connected to the equipment that produces industrial acidic wastewater by installing and tightening the screws and nuts on the flange ring. Specifically, in actual use, the equipment that produces industrial acidic wastewater can be an acid storage tank and a pickling and phosphating production line. In addition, it should be further explained that the material of the flange ring proposed in the present application must have good corrosion resistance to cope with the erosion of the acidic environment. In addition, in actual preparation, the cooperation between the electronic diversion valve tube 201 and the flange ring can be set to be detachable, so that the flange ring can be quickly maintained and replaced when it is worn or damaged.

[0058] In addition, reference Fig. 9 and Fig.10It can also be known that in the present application, a transmission rod 211 is slidably inserted into the center point of the filter ring 210, a stabilizing frame 208 is fixed to the side of the filter ring 210 facing the flange ring, one end of the transmission rod 211 passes through the stabilizing frame 208 to fix a force disk 205 that is compatible with the electronic diversion valve tube 201, and a return spring 206 is installed between the reverse side of the force disk 205 and the stabilizing frame 208.

[0059] It should be clear that in the actual operation of the present application, in order to ensure the stability of the cooperation between the return spring 206 and the stabilizing frame 208, reference Fig. 9 and Fig.10 It can be seen that a spring seat 207 for receiving the return spring 206 is fixed on the top of the stabilizing frame 208 , wherein the stabilizing frame 208 is provided with the return spring 206 installed between the spring seat 207 and the reverse side of the force-bearing disk 205 .

[0060] In addition, in the present application, a plurality of connecting tubes 202 are fixed to the outside of the electronic diversion valve tube 201, and both ends of the connecting tubes 202 are connected to the inside of the electronic diversion valve tube 201, and the two ends of the connecting tubes 202 are respectively arranged in the electronic diversion valve tube 201 near the front and back sides of the filter ring 210.

[0061] It should be noted that in the present application, during the filling process of the industrial acidic wastewater in the electronic diversion valve tube 201, the transmission rod 211 is moved toward the second pipe fitting 1 by means of contact with the force plate 205, and during the movement, a neutralizing liquid equal to the industrial acidic wastewater is allowed to enter the second pipe fitting 1.

[0062] Specifically, during the actual operation of the first pipe fitting 2 in the present application, the movement of the transmission rod 211 is pushed by the force plate 205. The movement of the force plate 205 occurs along with the filling process of the industrial acidic wastewater. When the industrial acidic wastewater reaches a certain amount, the force plate 205 will be subjected to sufficient pressure, thereby pushing the transmission rod 211 to move in the direction of the second pipe fitting 1. The movement of the transmission rod 211 causes the opening of the connecting pipe 202 to gradually increase until it is fully opened. In this way, the flow rate of the industrial acidic wastewater can be controlled to ensure that it flows into the second pipe fitting 1 at a stable speed. At the same time, since the other end of the connecting pipe 202 is connected to the storage space of the neutralizing liquid, during the movement of the transmission rod 211, the neutralizing liquid will also flow into the second pipe fitting 1 in a corresponding amount and mix with the industrial acidic wastewater for neutralization treatment. This design not only ensures the continuity and uniformity of the neutralization reaction, but also further improves the treatment efficiency and treatment effect by precisely controlling the flow rate of the neutralizing liquid.

[0063] refer to Figure 4-Figure 7It can be seen that in the present application, the second pipe fitting 1 includes: a transfer pipe 101, which is used to communicate with the first pipe fitting 2 and the third pipe fitting 3, and an injection pipe 105 for adding neutralizing liquid is installed at one end of the surface of the transfer pipe 101. An electrolytic dish 113 is fixed to the bottom end of the inner wall of the transfer pipe 101, and the electrolytic dish 113 is fixed with an isolation cover 109 attached to the top surface of the inner wall of the transfer pipe 101. A connecting notch 114 adapted to the injection pipe 105 is opened at one end of the top of the isolation cover 109. A diversion funnel 112 is fixed to the position of the isolation cover 109 facing the first pipe fitting 2, and the diversion funnel 112 is used to transfer the industrial acidic wastewater from the first pipe fitting 2 to the electrolytic dish 113.

[0064] It should be added that in the present application, a plurality of assembly pins 106 are fixed to the outside of the transfer tube 101 near the end of the diversion funnel 112, and a locking strap 107 capable of inserting a screw is fixed to one end of each assembly pin 106. Fig. 9 and Fig.10 It can be seen that in the present application, the electronic diversion valve tube 201 is provided with a plug-in interface 204 whose number and position match the assembly pin 106 at one end away from the flange ring, wherein the plug-in interface 204 and the assembly pin 106 are adapted, and the outer part of the filter ring 210 is also fixed with a number and position of a snap-fit ​​folding plate 209 that matches the plug-in interface 204, and a through hole that can be passed by a screw is installed in the snap-fit ​​folding plate 209, and a plurality of screw grooves 203 are provided at a position near the plug-in interface 204 on the outer part of the electronic diversion valve tube 201, and the screw grooves 203 are adapted to the screw, refer to Figure 1-Figure 3 It can be seen that the first pipe 2 and the second pipe 1 cooperate with each other through the screw and the screw groove 203 to fit the locking strap 107 with the snap-fit ​​folding plate 209 and install them together, thus completing the assembly between the first pipe 2 and the second pipe 1.

[0065] It should also be noted that the reference Figure 6 It can be seen that in the present application, a damping rod 110 is fixed to one end of the interior of the isolation cover 109 away from the diversion funnel 112, and a sealing ring 117 is fixed to one end of the telescopic end face of the damping rod 110 facing the diversion funnel 112. The sealing ring 117 is adapted to the diversion funnel 112, and a shielding folding plate 111 is fixed to the top end of the outside of the sealing ring 117. The top surface of the shielding folding plate 111 is attached to the inner wall of the top surface of the isolation cover 109 and is adapted to the connecting notch 114.

[0066] It should be noted that the reference Figure 6It can be seen that this structure is the first structure in the second pipe fitting 1. The structure is punched by the process acidic wastewater through the sealing ring 117 to realize the operation of the damping rod 110. In actual use, the structure can effectively control the flow rate of the industrial acidic wastewater and ensure the mixing uniformity of the neutralization liquid and the acidic wastewater. The damping rod 110 is used to control the flow of the neutralization liquid. When the industrial acidic wastewater enters the electrolytic dish 113 through the guide funnel 112, the damping rod 110 retracts and allows the neutralization liquid to flow.

[0067] In addition, as a supplement to the first structure, refer to Figure 5 It can be seen that the second structure inside the second pipe fitting 1 is disclosed. Specifically, in the present application, a damping rod 110 is fixed to one end of the isolation cover 109 away from the diversion funnel 112. The telescopic end of the damping rod 110 can extend into the interior of the first pipe fitting 2. A shielding folding plate 111 is fixed to the outside of the telescopic end of the damping rod 110. The shielding folding plate 111 and the connecting gap 114 are matched. When the industrial acidic wastewater enters the second pipe fitting 1, the telescopic end of the damping rod 110 runs and allows the neutralizing liquid with an equal amount to the industrial acidic wastewater to enter along the connecting gap 114.

[0068] It should be noted that the second structure further optimizes the flow control of the neutralizing liquid in design compared to the first structure by allowing the damping rod 110 to pass through the guide funnel 112 and the transmission rod 211. Specifically, in the second structure, the telescopic end of the damping rod 110 is fixedly connected to the transmission rod 211, so that the movement of the damping rod 110 is synchronized with the transmission rod 211. When the transmission rod 211 moves due to the push of the force plate 205, the damping rod 110 also telescopes and retracts accordingly, thereby adjusting the flow rate of the neutralizing liquid. The linkage mechanism of the second structure ensures that the neutralizing liquid and the industrial acidic wastewater are mixed more evenly, while improving the efficiency of the neutralization reaction.

[0069] refer to Figure 7 It can be seen that in the present application, the two ends of the bottom of the transfer tube 101 are respectively installed with power supply seats 108, the transfer tube 101 is installed with a sealing cover 103 away from the diversion funnel 112, and two electrode tubes 102 are inserted in the sealing cover 103. The electrode tube 102 is arranged at the middle end position inside the electrolytic dish 113, and the two electrode tubes 102 are respectively connected to the two power supply seats 108. It should be added that, referring to Figure 7 It can be seen that tube openings 115 adapted to the two electrode tubes 102 are respectively opened on both sides of one end of the electrolytic vessel 113, and power supply ports 116 adapted to the connectors of the power supply seat 108 are respectively opened on both ends inside the electrolytic vessel 113.

[0070] It should be clear that reference Figure 8It can be seen that in the present application, the surface of the electrode tube 102 is a conductive and corrosion-resistant material, specifically stainless steel, and the inner wall of the electrode tube 102 is a non-conductive and corrosion-resistant material, specifically polytetrafluoroethylene. It should be noted that when the present application is actually in operation, the electrode tube 102 acts as two electrodes in the electrolysis method. During the electrolysis process, the conductive and corrosion-resistant surface of the electrode tube 102 can effectively conduct current, while the inner wall of polytetrafluoroethylene ensures the stability and durability of the electrode tube 102 in a strong acidic environment.

[0071] Furthermore, in this application, reference is made to Fig.11 and Fig.12 It can be seen that the third pipe fitting 3 includes: a three-way pipe seat 312, and the two pipe heads at the horizontal position of the three-way pipe seat 312 are respectively a connecting pipe 301 and a discharge pipe 305, the connecting pipe 301 is used to connect with the second pipe fitting 1, and the discharge pipe 305 is used to discharge gas, and the pipe head at the vertical position of the three-way pipe seat 312 is an extension pipe 306, and a barrier ring 307 is fixed inside the extension pipe 306, and a support platform 304 is installed at a position opposite to the extension pipe 306 in the three-way pipe seat 312, and a sensor 303 for detecting gas components is installed in the support platform 304, and an isolation plate 302 for cooperating with the barrier ring 307 is fixed at the bottom of the support platform 304 near one end of the connecting pipe 301, and a filter component with a hollow middle part is installed at the bottom of the extension pipe 306, and the gas enters along the connecting pipe 301, flows from the surface of the filter component under the barrier of the isolation plate 302 and the barrier ring 307, and is discharged toward the discharge pipe 305 through the interior of the filter component.

[0072] It should be added that reference Figure 1-Figure 12 It can be seen that in the present application, an exhaust pipe 104 for connecting with the connecting pipe 301 is fixed to the outside of the transfer pipe 101, and flange rings are installed on the outside of the exhaust pipe 104 and the connecting pipe 301. The connection between the connecting pipe 301 and the transfer pipe 101 is achieved by installing bolts and nuts between the two flange rings.

[0073] It should be clear that in the present application, the gas is divided into the gas produced by the neutralization method and the gas produced by the electrolysis method, which are respectively gas A and gas B. Gas A mainly contains carbon dioxide and water vapor produced after the neutralization reaction, while gas B mainly contains hydrogen and oxygen produced during the electrolysis process. In the present application, gas A and gas B enter the three-way pipe seat 312 through the connecting pipe 301 of the third pipe fitting 3, and then are discharged through the discharge pipe 305 respectively. The sensor 303 is used to monitor the gas composition in real time to ensure the safety of gas discharge. The hollow design of the middle part of the filter component allows the gas to fully contact the filter material when passing through, effectively removes possible particulate impurities, and ensures the cleanliness of the exhaust gas. The use of the isolation plate 302 and the barrier ring 307 further ensures the separation and purity of the gas during the discharge process, prevents the mixing of different gases, and thus improves the operating efficiency and safety of the entire system.

[0074] In addition, reference Fig.11 and Fig.12 It can also be known that in the present application, the filtering component includes: a guide cone tube 308, a threaded sleeve 311 is rotatably connected to the outside of the wide mouth end, one end of the threaded sleeve 311 is threadedly connected to the extension tube 306, and the other end of the threaded sleeve 311 is threadedly installed with a sealing cap 309, and the sealing cap 309 is filled with activated carbon 310 for adsorbing liquid, and a groove is opened at the center point of the activated carbon 310 in the sealing cap 309, and the groove is adapted to the tapered end of the guide cone tube 308.

[0075] It should be further added that in the present application, a plurality of grooves are provided on the outer surface of the guide cone tube 308, and a spiral arm 313 is fixed in each groove. When the gas passes through the spiral arm 313 on the surface of the guide cone tube 308, it cooperates with the inner wall of the threaded sleeve 311 to form a gas channel for accelerating the gas flow rate.

[0076] In addition, it should be noted that since both the neutralization method and the electrolysis method require a certain amount of time to react, during actual operation, the sensor 303 and the electronic diversion valve tube 201 are associated through the programming of an existing computer. Specifically, when the sensor 303 collects gas A, the electronic diversion valve tube 201 is closed, and the flow of gas A is continuously obtained. When the flow of gas A gradually stabilizes, the computer controls the operation of the power socket 108 to start electrolysis of the neutralized solution. When the sensor 303 obtains gas B and the flow of gas B gradually decreases from large to zero, the computer controls the electronic pump installed outside the two conductive tubes to complete the recovery of the solution. Finally, the computer opens the electronic diversion valve tube 201 again to complete the primary cleaning of industrial acidic wastewater.

[0077] It should be added that in order to further improve the intelligence of the technical solution proposed in this application, during the actual operation of this application, a pH sensor and a liquid flow sensor can be installed in the transfer tube 101, wherein the pH sensor is used to monitor the pH value of the solution in real time to ensure that the neutralization reaction reaches the expected pH range, while the liquid flow sensor is used to accurately control the flow rate of the solution to ensure the stability and efficiency of the entire treatment process.

[0078] Although the applications of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these applications without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended applications and their equivalents.
