Description

Technical Field

[0001] The present invention belongs to the technical field of industrial sewage treatment, and particularly relates to an industrial sewage hierarchical treatment device and method. Background Art

[0002] Industrial sewage mainly comes from the wastewater generated in the production process, including cooling water, washing water, process wastewater, etc. These wastewaters contain various harmful substances, such as entanglements, heavy metals, organic solvents, acid-base substances, suspended solids, etc. Direct discharge of industrial sewage without treatment will seriously pollute water bodies and destroy the water ecological balance. Due to the different components of industrial sewage, etc., it is usually necessary to carry out hierarchical treatment. Primary treatment usually removes some larger suspended solids and entanglements. Secondary treatment mostly uses chemicals to neutralize its pH value and remove large solid particles. Tertiary treatment mostly uses air flotation to wrap and float the suspended solids in the water to remove them. An external device such as an air compressor is used to aerate the sewage to make the suspended solids combine with the bubbles. In recent years, with the recycling of energy and the maturity of electrolyzed water technology, the method of electrolyzing sewage has also been used in tertiary treatment for sewage treatment.

[0003] After retrieval, the Chinese patent with the application number 202011278043.8 discloses a micro-electrolysis treatment and collection device for industrial sewage, including a treatment tank. A treatment chamber is provided in the treatment tank. An adjustment mechanism is provided in the treatment chamber. The adjustment mechanism includes a discharge pipe fixedly installed on the upper end wall of the treatment chamber and connected to the outside of the treatment tank. A placement shaft is fixedly installed on the lower end surface of the discharge pipe. A placement box is provided in the placement shaft; the industrial sewage to be treated is discharged, and an appropriate amount of micro-electrolysis agent is added according to the discharge amount of the industrial sewage, so as to avoid waste caused by excessive addition of the micro-electrolysis agent or poor micro-electrolysis effect caused by too little micro-electrolysis agent, which affects the sewage treatment effect, and drives the micro-electrolysis material to fully generate an electrolysis reaction with the sewage, so that the sewage can be quickly coagulated.

[0004] Although the above-mentioned patent literature promotes the coagulation of pollutants in sewage through electrolysis of water, the bubbles generated during the electrolysis process (mainly composed of hydrogen with high energy density and oxidizing oxygen) are not effectively collected. This not only wastes the electrical energy consumed during the electrolysis process, but also wastes precious clean energy and industrial raw materials, resulting in a double waste of energy and resources. In the prior art, most manufacturers, due to cost and technical complexity considerations, usually do not recover the gas generated by electrolysis during the sewage treatment process. Even if a few manufacturers attempt to recover it, they often adopt complex processes of multi-stage separation. First, it is necessary to separate the gas from the suspended matter floating with the bubbles by means of precipitation, filtration, etc.; then, technologies such as pressure swing adsorption, membrane separation, or cryogenic distillation are used to separate hydrogen and oxygen. These separation methods not only have long process flows, huge equipment investments, but also high operating energy consumption and maintenance costs, and the economic benefits are not good. Summary of the Invention

[0022] The present invention also provides an industrial sewage grading treatment method, and this usage method includes the following steps:

[0023] S1, continuously introduce sewage through the water inlet pipe on one side of the sewage treatment device body, and it will sequentially enter the primary treatment chamber, the secondary treatment chamber and the tertiary treatment chamber for grading treatment.

[0024] S2, when the sewage is shunted by the shunt assembly and enters both sides of the cavity of the tertiary treatment chamber, then energize the electrolytic electrode rods, so that hydrogen is generated between the anodes of the electrolytic electrode rods and the sewage, and oxygen is generated between the cathodes and the sewage, and bubbles are formed to wrap the suspended matter upwards.

[0025] S3, as the sewage level gradually rises, it will enter the gas separation and recovery mechanism. Due to the accumulation of sewage inside the gas separation and recovery mechanism, it will further push the ventilation assembly to release the connection effect between the gas separation and recovery mechanism and the top of the air extraction mechanism.

[0026] S4, as the sewage continuously enters the gas separation and recovery mechanism, it will drive the air extraction mechanism to operate, resulting in negative pressure in the inner cavity, so as to suck away some of the gas on the sewage liquid surface inside the gas separation and recovery mechanism and recycle it into the hydrogen fuel cell to provide electrical energy, realizing the recycling of energy. And the filter assembly inside the gas separation and recovery mechanism will block and retain the suspended matter in the sewage, and the water will be discharged and recycled through the external water pipe at the bottom of the gas separation and recovery mechanism.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] (1) By providing a flow splitting component and a gas separation and recovery mechanism in the present invention, when sewage can be guided into the interior of the tertiary treatment chamber through the flow splitting component, since the flow splitting component causes the sewage inside the tertiary treatment chamber to be split to both sides, and the sewage on both sides can be separated from the bubbles generated by electrolyzing hydrogen and oxygen with electrolytic electrode rods. Then, as the water flows upward into the gas separation and recovery mechanism, low-cost recovery of hydrogen and oxygen in the bubbles at the top of the sewage can be achieved, avoiding energy damage and reducing costs.

[0029] (2) By providing a gas separation and recovery mechanism and a ventilation component in the present invention, when sewage enters the gas separation and recovery mechanism, a part inside the gas separation and recovery mechanism will descend, thereby squeezing the inclined surfaces at the inner sides of the bottoms of both ends of the ventilation component, causing the two ends of the ventilation component to move away from each other. This enables the inner ends at the top to contact and seal the top part of the air extraction mechanism, facilitating the smooth linkage between the top of the gas separation and recovery mechanism and the top of the air extraction mechanism, and facilitating subsequent separation and recycling of the gas.

[0030] (3) By providing an air extraction mechanism and a hydrogen fuel cell in the present invention, when the ventilation component removes the sealing blockage of the top of the air extraction mechanism and the top of the gas separation and recovery mechanism, and there is continuous water flow inside the gas separation and recovery mechanism, the rotating water wheel will rotate continuously at this time. Thus, the air extraction mechanism will extract some of the gas inside the bubbles at the top of the sewage in the recovery tank. Finally, the gas can be pumped back and introduced into the parts of the cathode and anode inside the hydrogen fuel cell, enabling hydrogen to enter the anode part and oxygen to enter the cathode part, and then smoothly generating electrons to provide energy for the entire hydrogen fuel cell, achieving energy recovery and utilization.

Specific embodiments

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] As Figures 1 to 9As shown in the figure, the present invention provides an industrial sewage grading treatment device and method, including a sewage treatment device body 1, and further including: a tertiary treatment chamber 4, which is arranged at one end of the inner cavity of the sewage treatment device body 1; electrolytic electrode rods 5, which are arranged at the bottom of the inner cavity of the tertiary treatment chamber 4; a flow splitting component 6, which is arranged in the middle of the inner cavity of the tertiary treatment chamber 4; a gas separation and recovery mechanism 7, which is arranged on one side of the sewage treatment device body 1 and is located at the top of one side of the tertiary treatment chamber 4, and the top is connected to a hydrogen fuel cell 12 located on one side of the sewage treatment device body 1 through an air extraction mechanism 9. An air venting component 10 is arranged at the top of the gas separation and recovery mechanism 7, and the air venting component 10 blocks the connection ends at the top of the air extraction mechanism 9 and the gas separation and recovery mechanism 7. Among them, the gas separation and recovery mechanism 7 includes a recovery tank 701 arranged at the top of one side of the sewage treatment device body 1. Rotating water wheels 702 are movably sleeved at the top of one side of the two recovery tanks 701. A separation component 703 is movably installed in the inner cavity of the recovery tank 701 and is located at the bottom of the rotating water wheel 702. A water passing component 704 is arranged in the inner cavity of the recovery tank 701 and is located below the rotating water wheel 702.

[0043] Through the flow splitting component 6, the sewage can be split and enter the two ends of the inner cavity of the tertiary treatment chamber 4. Then, by energizing the electrolytic electrode rods 5, an electrolytic reaction occurs in the internal sewage to produce oxygen and hydrogen. The oxygen and hydrogen will form bubbles in the water, which can carry the suspended matter upward. Subsequently, the water flow first rotates through the rotating water wheel 702 and is guided into the recovery tank 701. The overall separation component 703 will be pushed and squeezed downward by the water pressure until the inside of the separation component 703 is pushed open through the water passing component 704, enabling the sewage to flow smoothly downward. And the air venting component 10 releases the seal on the top of the air extraction mechanism 9 and the recovery tank 701, and part of the gas inside the bubbles at the top of the sewage will be extracted and absorbed by the air extraction mechanism 9.

[0044] As Figure 1 shown, a primary treatment chamber 2 and a secondary treatment chamber 3 are respectively arranged at the other end and the middle of the sewage treatment device body 1.

[0045] Adopting the above solution: When an external water pipe is connected to the top of one side of the sewage treatment device body 1 close to the primary treatment chamber 2, the sewage can be introduced into the interiors of the primary treatment chamber 2, the secondary treatment chamber 3, and the tertiary treatment chamber 4 for grading treatment. Since the parts of the primary treatment chamber 2 and the secondary treatment chamber 3 belong to the prior art, no further description will be given.

[0046] As Figure 1 and Figure 2 shown, the flow splitting component 6 includes a fixed shell 601, a water pipe 602, and a guide plate 603;

[0047] The fixed housing 601 is fixedly installed at the top on one side of the inner cavity of the tertiary treatment chamber 4. The water pipe 602 is arranged in the middle of the tertiary treatment chamber 4, and one end of the water pipe 602 is communicated with the fixed housing 601. The flow guide plate 603 is arranged at the other end of the water pipe 602.

[0048] Adopting the above scheme: By arranging the flow guide plate 603, since the water pipe 602 is higher than the top of the flow guide plate 603, the sewage can smoothly pass through the water pipe 602 and be sprayed out in a fountain shape from the other end. Through the design of the flow guide plate 603, the sprayed sewage can impact and separate the sewage at both ends of the tertiary treatment chamber 4, and synchronously separate the bubbles generated by energizing the electrolytic electrode rods 5.

[0049] As Figure 4 shown, the separation component 703 includes a movable plate 7031, a limiting rod 7032, and a first spring 7033;

[0050] The movable plate 7031 is movably installed in the inner cavity of the recovery box 701. The top of one side of the movable plate 7031 is slidably sleeved with the inside of the recovery box 701 through the limiting rod 7032. The limiting rod 7032 is elastically connected with the inside of the recovery box 701 through the first spring 7033.

[0051] Adopting the above scheme: By arranging the first spring 7033, when the movable plate 7031 is pushed downward by the water pressure, the first spring 7033 will be compressed, enabling the middle of the water passing component 704 to be smoothly pushed open, allowing the water flow to go downward. And part of the water pressure will be lost, so that part of the elastic force of the first spring 7033 is released to push the movable plate 7031 upward, which will assist in pushing part of the gas at the top of the sewage into the air extraction mechanism 9. When the water passing component 704 stops being pushed, the water pressure will continue to push the movable plate 7031 downward.

[0052] As Figure 5 and Figure 6 shown, the water passing component 704 includes a check valve flap 7041, a pipe jacking frame 7042, and a sealing ring 7043;

[0053] The check valve flap 7041 is arranged inside the movable plate 7031. The pipe jacking frame 7042 is arranged inside the recovery box 701 and is located at the bottom of the movable plate 7031. The sealing ring 7043 is arranged at the top of the pipe jacking frame 7042. Adopting the above scheme: By arranging the sealing ring 7043, when the movable plate 7031 moves downward, the check valve flap 7041 at the top of the pipe jacking frame 7042 will be turned upward. Due to the design of the sealing ring 7043, the tightness of the gap between the top of the check valve flap 7041 and the pipe jacking frame 7042 can be enhanced.

[0054] As Figure 5 and Figure 6As shown, a filter assembly 8 located below the top pipe rack 7042 is installed inside the recovery box 701, and the filter assembly 8 includes a movable frame 801 and a filter medium 802, and the hydrogen fuel cell 12 includes a battery shell 1201, a top cover 1202 and an electrode rod 1203;

[0055] The movable frame 801 is movably installed inside the recycling box 701, the filter medium 802 is arranged inside the movable frame 801, the battery shell 1201 is arranged on one side of the sewage treatment device body 1 and is located below the recycling box 701, the top cover 1202 is arranged on the top of the battery shell 1201, the electrode rod 1203 is arranged inside the electrode rod 1203, and the electrode rod 1203 is electrically connected to one side of the electrolytic electrode 5 through an electric wire.

[0056] The above scheme is adopted: through the design of the filter medium 802, the suspended matter electrolyzed in the sewage can be filtered, and by pulling the movable frame 801 and the filter medium 802 outward, the filter medium 802 can be replaced, and the overall design of the hydrogen fuel cell 12 can provide power to the electrolysis pole 5.

[0057] like Figure 8 and Figure 9 As shown, the air extraction mechanism 9 includes a driving gear 901, a first driven gear 902, a connecting rod structure 903, a linkage assembly 904, an air suction fan blade 905 and an air extraction pipe 906;

[0058] The top of the recovery box 701 is fixedly connected to the hydrogen fuel cell 12 through the exhaust pipe 906, the driving gear 901 is arranged at one end of the rotating water wheel 702, the first driven gear 902 is arranged inside the recovery box 701, and the surface of the first driven gear 902 is meshed with the surface of the driving gear 901, the linkage assembly 904 is arranged on one side of the recovery box 701, and the linkage assembly 904 is transmission-connected to the first driven gear 902 through the connecting rod structure 903, and the suction fan blade 905 is arranged in the inner cavity of the driving gear 901 and is located on the outside of the linkage assembly 904.

[0059] The above scheme is adopted: by providing a connecting rod structure 903, when the rotating water wheel 702 is driven to rotate by sewage, it can drive the first driven gear 902 to drive the connecting rod structure 903 to rotate, and then the linkage component 904 can be transmitted through the connecting rod structure 903, so that the linkage component 904 drives the suction fan blade 905 to rotate, so that a negative pressure area is generated on one side of the suction fan blade 905 to extract gas.

[0060] like Figure 9 As shown, the linkage assembly 904 includes a first bevel gear rod 9041, a second bevel gear rod 9042 and a second driven gear 9043;

[0061] The first bevel gear rod 9041 is arranged on one side of the recycling bin 701, and one end of the first bevel gear rod 9041 is sleeved with one end of the connecting rod structure 903. The second bevel gear rod 9042 is arranged inside the recycling bin 701, and the end of the second bevel gear rod 9042 meshes with the end of the first bevel gear rod 9041. The second driven gear 9043 is arranged at the bottom of the second bevel gear rod 9042, and the second driven gear 9043 meshes with the surface of the suction fan blade 905.

[0062] With the above solution: by providing the second driven gear 9043, when the connecting rod structure 903 drives the first bevel gear rod 9041 to rotate, the gears on the surface can drive the second bevel gear rod 9042 to rotate, and then the gears on the surface of the second driven gear 9043 drive the suction fan blade 905 to rotate.

[0063] As Figure 9 shown, the ventilation assembly 10 includes a ventilation baffle 101, a limiting shaft 102, a connecting frame 103, a second spring 104 and a triangular block 105;

[0064] The ventilation baffle 101 is movably installed at both ends of the top of the movable plate 7031. The limiting shaft 102 is arranged inside the recycling bin 701 and is located above the ventilation baffle 101. The connecting frame 103 is installed on the top of the ventilation baffle 101, and the surface of the connecting frame 103 is movably sleeved with the surface of the limiting shaft 102. The outside of the connecting frame 103 is elastically connected to the inside of the recycling bin 701 through the second spring 104. The triangular block 105 is arranged at the inner end of the bottom of the connecting frame 103. A breathable and waterproof film 11 is arranged inside the recycling bin 701 above the ventilation baffle 101.

[0065] With the above solution: by providing the triangular block 105, when the movable plate 7031 moves down to the bottom, it will cause the bottom of both ends to squeeze and push the inclined surface of the triangular block 105, and then push the connecting frame 103 and the ventilation baffle 101 to move away from each other. When the movable plate 7031 is pulled up to one end, the elastic force of the second spring 104 will be released to push the connecting frame 103 and the ventilation baffle 101 to reset, so as to scrape off some impurities adhering to the bottom of the breathable and waterproof film 11 and avoid blockage.

[0066] The present invention also provides an industrial sewage grading treatment method, and the treatment method includes the following steps:

[0067] S1, the user can first continuously introduce sewage through the water inlet pipe on one side of the sewage treatment device body 1, and it will enter the primary treatment chamber 2, the secondary treatment chamber 3 and the tertiary treatment chamber 4 in sequence to achieve grading treatment;

[0068] S2. After the sewage is blocked by the fixed housing 601 and enters the water pipe 602, it will be diverted by the guide plate 603 and enter both sides of the cavity of the three-stage treatment chamber 4. Then, the electrolytic electrode rods 5 are energized, so that hydrogen is generated between the anode of the electrolytic electrode rods 5 and the sewage, and oxygen is generated between the cathode and the sewage. Then, due to the impact of the water flow at the position of the guide plate 603, the bubbles of hydrogen and oxygen generated by the anode and cathode in the sewage will be separated. Subsequently, gas bubbles will be generated inside the sewage to wrap the suspended matter and move upward;

[0069] S3. As the sewage level gradually rises, it will enter the rotating water wheel 702 and drive the rotating water wheel 702 to rotate, so as to seal and divert the sewage with bubbles into the recovery tank 701. As a result, the whole of the movable plate 7031 will move downward until the one-way valve flap 7041 inside the movable plate 7031 is opened by the top end of the pipe jacking frame 7042. Then, the sewage will fall through the pipe jacking frame 7042, pass through the filter medium 802 for filtration and then be discharged, while the suspended matter will be left on the top of the filter medium 802;

[0070] S4. As the sewage continuously enters the gas separation and recovery mechanism 7, it will drive the air extraction mechanism 9 to operate, causing a negative pressure in the inner cavity, so as to suck away and recover some of the gas on the sewage liquid surface inside the gas separation and recovery mechanism 7 into the hydrogen fuel cell 12 to provide electrical energy, realizing the recovery and utilization of energy. The filter component 8 inside the gas separation and recovery mechanism 7 will block and retain the suspended matter in the sewage, and the water will be discharged and recovered through the external water pipe at the bottom of the gas separation and recovery mechanism 7.

[0071] Specifically, since the downward movement of the movable plate 7031 will cause the bottom parts on both sides to squeeze the inclined surfaces of the triangular blocks 105, and push the triangular blocks 105, the connecting frame 103 and the ventilation baffle 101 to move away from each other, the ventilation baffle 101 can release the sealing effect on the communicating part between the top of the recovery tank 701 and the top of the air extraction pipe 906. Since the rotating water wheel 702 is continuously driven by the water flow to rotate, it will rotate through the driving gear 901. Due to the meshing relationship between the surfaces of the driving gear 901 and the first driven gear 902, the first driven gear 902 can be driven to rotate. Then, through the connecting rod structure 903, the first bevel gear rod 9041 can be linked to rotate. At the same time, due to the meshing relationship between the ends of the first bevel gear rod 9041 and the second bevel gear rod 9042, the second bevel gear rod 9042 and the second driven gear 9043 can be driven to rotate. Finally, through the meshing relationship between the surfaces of the second driven gear 9043 and the suction fan blade 905, the whole suction fan blade 905 can be driven to rotate, so that a negative pressure area is generated on one side of the suction fan blade 905, and some of the gas inside the bubbles on the sewage surface in the inner cavity of the recovery tank 701 can be extracted through the air extraction pipe 906, and the breathable waterproof membrane 11 can block the sewage.

[0072] It is not difficult to understand that in this Embodiment 1 Figure 1 only shows the front-back relationship between the primary treatment chamber 2, the secondary treatment chamber 3, and the tertiary treatment chamber 4. In practice, for industrial sewage with a small treatment volume, the attached Figure 1 overall structure can be adopted. When it comes to industrial sewage with a large treatment volume, the primary treatment chamber 2 and the secondary treatment chamber 3 can be regarded as separate entities.

[0073] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0074] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
