Description

Technical Field

[0001] This invention relates to the field of industrial wastewater treatment, specifically to an industrial wastewater treatment device with exhaust gas purification function. Background Technology

[0002] With the rapid development of industrial production, the problem of industrial wastewater and exhaust gas emissions has become increasingly serious, posing a grave threat to the environment and human health. Traditional industrial wastewater treatment facilities mainly focus on the purification of wastewater, often neglecting the control and treatment of exhaust gas emissions. However, in the industrial production process, many wastewater treatment stages generate exhaust gases containing harmful substances. If these exhaust gases are discharged directly into the atmosphere without treatment, they will seriously pollute the air, affect the ecological environment, and even endanger human health.

[0003] In the process of industrial wastewater treatment, the sludge produced in the wastewater often contains a certain amount of waste gas. These waste gases mainly include harmful gases remaining in the gaps between sludge particles, such as hydrogen sulfide. If they are directly discharged or improperly treated, they will cause secondary pollution to the environment. The lack of corresponding pretreatment measures for sludge makes it impossible to meet the actual needs.

[0004] Therefore, there is a need to provide an industrial wastewater treatment device with exhaust gas purification function, which aims to solve the above problems. Summary of the Invention

[0023] The designed extrusion mechanism effectively squeezes out and collects waste gas from the sludge, facilitating subsequent waste gas collection and treatment. Furthermore, the parallel arrangement of the protective inclined plate and the guide plate effectively prevents sludge from entering the rear of the extrusion plate, further improving sludge treatment efficiency. The extrusion process disrupts the gas-sealing structure within the sludge, making it easier to release and collect waste gas, thus increasing treatment efficiency. Simultaneously, the extrusion process reduces the volume of the sludge, making it more compact and facilitating subsequent transportation, storage, and disposal, thereby enhancing the overall effectiveness of sludge treatment.

[0024] The exhaust gas purification mechanism can convert the pressure generated during sludge treatment into the power for injecting purification liquid, thereby realizing the resource utilization of waste and reducing energy consumption. By integrating the two processes of sludge treatment and exhaust gas purification, the overall operating cost is reduced and the economic feasibility of the system is improved. At the same time, the wastewater purification mechanism can effectively achieve wastewater purification.

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0043] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0044] Example 1

[0045] See Figures 1-9 An industrial wastewater treatment device with exhaust gas purification function includes a wastewater injection pipe 1, a first treatment tank 2 connected to the wastewater injection pipe 1, a third treatment tank 62 connected to the first treatment tank 22 via a second treatment tank 22, and a fourth treatment tank 63 connected to the third treatment tank 62 via a fourth pipe 64. The device also includes:

[0046] The material turning and stirring mechanism is installed inside the first treatment tank 2 and is used for water flow to drive the turning of sludge and for forward and reverse stirring treatment. The material turning and stirring mechanism includes a rotating sleeve shaft 15 and a stirring shaft 18 for forward and reverse stirring, and an impeller 3 for stirring drive. There is a pair of impellers 3, which are symmetrically distributed below the wastewater injection pipe 1. The two impellers 3 are arranged in opposite directions, and the impellers 3 are rotatably installed inside the first treatment tank 2 through the impeller shaft 4. The rotating sleeve shaft 15 and the stirring shaft 18 are arranged in opposite directions.

[0047] Furthermore, the material turning and mixing mechanism also includes a guide plate 5 and a flow divider 6 for guiding materials, and a material turning blade 7 for turning materials. The material turning blade 7 is rotatably installed inside the first processing box 2 via a material turning shaft 8. The material turning shaft 8 is rotatably connected to an impeller shaft 4 via a first synchronous belt 9. The guide plate 5 and the flow divider 6 are installed below the impeller 3. A material guiding slope 20 is installed below the material turning blade 7 and is installed inside the first processing box 2.

[0048] Furthermore, the material turning and stirring mechanism also includes a first gear 10 and a first connecting shaft 12 for driving the rotating sleeve shaft 15 and the stirring shaft 18 to connect in both directions of stirring. The first gear 10 is fixedly connected to the material turning shaft 8, and a second gear 11 is meshed on the first gear 10. The second gear 11 is rotatably mounted on one side of the first processing box 2 through the first connecting shaft 12. The first connecting shaft 12 is rotatably connected to the stirring shaft 18 through the second synchronous belt 13, and the first connecting shaft 12 on the other side is rotatably connected to the rotating sleeve shaft 15 through the third synchronous belt 14.

[0049] Furthermore, the rotating sleeve shaft 15 is provided with several L-shaped connecting rods 16, and several first stirring blades 17 for stirring are provided on the L-shaped connecting rods 16. Several second stirring blades 19 for stirring are provided on the stirring shaft 18. A coarse screen plate 21 is provided below the first stirring blades 17.

[0050] Preferably, during the purification of industrial wastewater, the wastewater is injected into the first treatment tank 2 through the wastewater injection pipe 1. Since two impellers 3 are symmetrically positioned below the wastewater injection pipe 1, the injection of wastewater drives the two impellers 3 to rotate in opposite directions. The wastewater and sludge fall downwards under the guidance of the guide plate 5 and the diversion plate 6. The turning blades 7 on the same side of the impeller 3 rotate under the synchronous drive of the first synchronous belt 9. Furthermore, due to the inclined guiding arrangement of the guide plate 5 and the diversion plate 6, the falling wastewater and sludge synchronously drive the turning blades 7 to rotate again, following the impeller 3 on the same side, maintaining the same direction of rotation as the impeller 3 on the same side. For example, as shown... Figure 3As shown, under the action of wastewater injection, the impeller 3 on the left and the turning blade 7 below rotate in the clockwise direction, while the impeller 3 on the right and the turning blade 7 below rotate in the counterclockwise direction. This facilitates the rotation and injection of wastewater and sludge, as well as subsequent driving operations. At the same time, the slope of the guide slope 20 is designed to prevent sludge from accumulating on the guide slope 20, and the rotation of the turning blade 7 is used for cleaning and scraping.

[0051] In addition, the turning blade 7 drives the turning shaft 8 to rotate, which in turn drives the first gear 10 to rotate. Under the meshing connection between the first gear 10 and the second gear 11, the first connecting shaft 12 is driven to rotate. Thus, the first connecting shaft 12 drives the second stirring blade 19 on the stirring shaft 18 to rotate under the synchronous drive of the second synchronous belt 13. On the other side, the first connecting shaft 12 drives the first stirring blade 17 on the rotating sleeve shaft 15 to rotate in the opposite direction under the synchronous drive of the third synchronous belt 14. This effectively achieves the forward and reverse cross rotation of the first stirring blade 17 and the second stirring blade 19, realizing good stirring of sludge in wastewater, which facilitates subsequent filtration and purification operations.

[0052] It should be noted that this forward and reverse rotation stirring method can significantly increase the degree of turbulence of materials on the coarse screen plate 21, so that wastewater and coagulants, flocculants and other chemicals can be fully mixed in a short time. The pipes for adding coagulants, flocculants and other chemicals are not shown in the diagram. In addition, this forward and reverse rotation stirring blades can form a complex flow field in the first treatment tank 2, including axial flow components and radial flow components. These components are in opposite directions, so that the wastewater circulates in the first treatment tank 2. This flow mode helps impurities and chemicals in the wastewater to quickly reach a uniform mixing state in all directions, thus facilitating subsequent filtration and purification operations.

[0053] Example 2

[0054] like Figures 1 to 14 As shown, this embodiment, based on embodiment 1, also includes a docking extrusion mechanism, which is installed inside the second processing box 22 and is synchronously driven by the material turning and stirring mechanism. The docking extrusion mechanism includes a partition plate 36 for material distribution and an extrusion plate 32 for extrusion setting. The extrusion plate 32 is provided with a protective inclined plate 33, and the extrusion plate 32 is provided with a plurality of perforating cones 34 for perforation and a bottom cleaning and scraping shovel 35.

[0055] Furthermore, the docking extrusion mechanism also includes a push plate 29 and a guide rod 31 for extrusion connection. The extrusion plate 32 is fixedly connected to the push plate 29 via the guide rod 31. The guide rod 31 is slidably connected to the second processing box 22. The push plate 29 is slidably connected to the inside of the docking box 23. A spring 30 is provided at the connection between the push plate 29 and the second processing box 22. A guide plate 40 is provided on the second processing box 22, and a fine sieve plate 41 is provided inside the second processing box 22. A partition plate 36 is provided on the fine sieve plate 41. A partition knife 37 is provided at the end of the partition plate 36. A through hole 38 adapted to slide connection of the perforated cone 34 is opened on the partition plate 36. A guide groove 39 adapted to slide connection of the push shovel 35 is opened on the partition plate 36. A limiting block 42 adapted to docking protective inclined plate 33 is provided inside the second processing box 22, and the protective inclined plate 33 is arranged parallel to the guide plate 40.

[0056] Furthermore, the docking extrusion mechanism also includes an eccentric wheel 28 for driving the extrusion plate 32 to reciprocate. The eccentric wheel 28 is rotatably mounted inside the docking box 23 via a third connecting shaft 27, and the eccentric wheel 28 is adapted to be rotatably connected to the side of the push plate 29. The third connecting shaft 27 is rotatably connected to a second connecting shaft 25 via a bevel gear pair 26. The second connecting shaft 25 is rotatably connected to a tilting shaft 8 via a fourth synchronous belt 24, and the bottom of the docking box 23 is provided with support feet 73 for support.

[0057] Preferably, in this embodiment, after the wastewater passes through the coarse screen plate 21, it falls onto the separator plate 36 under the guidance of the guide plate 40 for diversion. Subsequently, it undergoes filtration on the fine screen plate 41. Simultaneously, the turning blades 7 drive the turning shaft 8 to rotate, and the fourth synchronous belt 24 drives the second connecting shaft 25 on the docking box 23 to rotate. The second connecting shaft 25, connected by the bevel gear pair 26, drives the eccentric wheel 28 on the third connecting shaft 27 to rotate. Thus, under the eccentricity of the eccentric wheel 28 and the elastic reset action of the spring 30, the guide rod 31 drives the perforated cone 34 and the pusher shovel 35 on the extrusion plate 32 to reciprocate on the fine screen plate 41. Whenever the extrusion plate 32 on one side of the separator plate 36 performs extrusion filtration, the extrusion plate 32 on the other side moves and resets. Specifically, see... Figure 13 As shown, the extrusion plate 32 and the pusher shovel 35 can scrape the sludge on the fine screen plate 41. At the same time, the perforated cone 34 can perform multiple extrusion treatments, so that the waste gas in the sludge can be effectively squeezed out and collected, which facilitates the subsequent waste gas collection and treatment. In addition, the parallel arrangement of the protective inclined plate 33 and the guide plate 40 can effectively prevent sludge from entering the rear position of the extrusion plate 32, thereby further improving the sludge treatment efficiency.

[0058] The extrusion process can disrupt the gas-sealing structure in the sludge, making it easier for waste gas to be released and collected, thus improving the efficiency of waste gas treatment and the effect of sludge treatment. At the same time, the extrusion process can reduce the volume of sludge, making it more compact and facilitating subsequent transportation, storage and disposal. The sludge after removing waste gas is more stable, reducing problems such as sludge expansion and odor caused by waste gas release, and improving the overall effect of sludge treatment.

[0059] Example 3

[0060] like Figures 1 to 15 As shown, this embodiment, based on the above embodiment, also includes an exhaust gas purification mechanism, which is installed above the side of the second processing box 22 and is synchronously driven by the docking extrusion mechanism. It is used to extract the exhaust gas generated in the second processing box 22 and the first processing box 2 for purification. The exhaust gas purification mechanism includes a water tank 51 for exhaust gas extraction and a curved rod 61 for extraction drive. The curved rod 61 is rotatably installed on the docking box 23.

[0061] The wastewater purification unit is installed at the internal connection between the third treatment tank 62 and the fourth treatment tank 63 for the purification of wastewater.

[0062] Furthermore, the exhaust gas purification mechanism also includes a piston plate 55 and a traction rod 59 for driving the interior of the water tank 51 to extract the purified liquid. The piston plate 55 is slidably connected to the interior of the water tank 51 by a piston rod 56. The water tank 51 is fixedly installed on the side of the second treatment tank 22. One end of the piston rod 56 is fixedly connected to a pressing plate 58. One end of the traction rod 59 is hinged to the pressing plate 58. The other end of the traction rod 59 is fixedly connected to a connecting sleeve 60. The connecting sleeve 60 is adapted to be rotatably connected to a curved rod 61. One end of the curved rod 61 is fixedly connected to a third connecting shaft 27. The curved rod 61 is rotatably installed on the docking box 23 by a support frame 49. A vent hole 57 is provided on the water tank 51.

[0063] Furthermore, the exhaust gas purification mechanism also includes a third pipe 50 and a sixth pipe 74 for extraction, and an exhaust fan 44 for extracting exhaust gas. The water tank 51 is connected to the purification liquid storage tank 53 through the sixth pipe 74. A one-way valve 54 for water extraction is installed on the sixth pipe 74. The water tank 51 is connected to the spray pipe 48 through the third pipe 50. The spray pipe 48 is installed at the top inside the exhaust gas purification box 46. A drain pipe 47 is installed on the exhaust gas purification box 46. A one-way valve 52 for water outlet is installed on the third pipe 50. The exhaust fan 44 is connected to the interior of the second treatment box 22 through the first pipe 43, and the exhaust fan 44 is connected to the exhaust gas purification box 46 through the second pipe 45.

[0064] Furthermore, the wastewater purification mechanism includes a water pump 68 for pumping wastewater. The water pump 68 is installed inside the third treatment tank 62. The water pump 68 is connected to the inside of the third treatment tank 62 through a fifth pipe 67. A fine filter layer 66 is provided on the outside of the connection between the fifth pipe 67 and the inside of the third treatment tank 62. The water pump 68 is connected to the inside of the fourth treatment tank 63 through a fourth pipe 64.

[0065] Furthermore, the wastewater purification mechanism also includes a graphite layer 69, a sponge layer 70, and an activated carbon layer 71 for purification one by one. The graphite layer 69, the sponge layer 70, and the activated carbon layer 71 are installed one by one from bottom to top inside the fourth treatment box 63. An ultraviolet germicidal lamp 72 is installed at the top inside the fourth treatment box 63, and a drain pipe 65 is installed on the fourth treatment box 63.

[0066] Preferably, in this embodiment, the exhaust fan 44 can extract and process the exhaust gas in the first processing box 2 and the second processing box 22, and then inject it into the interior of the exhaust gas purification box 46 through the second pipe 45. The turning blade 7 drives the third connecting shaft 27 to rotate, and at the same time drives the curved rod 61 to rotate. Thus, under the rotatable connection between the curved rod 61 and the connecting sleeve 60, the piston plate 55 on the piston rod 56 is driven to reciprocate inside the water tank 51. Thus, under the connection between the outlet check valve 52 set on the third pipe 50 and the pumping check valve 54 set on the sixth pipe 74, the purification liquid in the purification liquid storage tank 53 is continuously drawn to the spray pipe 48 for spraying, thereby effectively realizing the purification treatment of exhaust gas.

[0067] The rotation of impeller 3 and turning blades 7 not only realizes the continuous compression of sludge to release waste gas, but also realizes the corresponding extraction of purification liquid and injection into the waste gas for purification. The pressure generated during sludge treatment is converted into the power for injection of purification liquid, realizing the resource utilization of waste and reducing energy consumption. By integrating the two processes of sludge treatment and waste gas purification, the overall operating cost is reduced and the economic feasibility of the system is improved.

[0068] After being screened by the fine sieve plate 41, the wastewater enters the third treatment tank 62. The water pump 68 operates, and under the filtration and screening effect of the fine filter layer 66, the water pump 68 draws the filtered wastewater through the fifth pipe 67 and injects it into the interior of the fourth treatment tank 63 through the fourth pipe 64. Thus, under the layer-by-layer purification effect of the graphite layer 69, the sponge layer 70 and the activated carbon layer 71, as well as the ultraviolet sterilization effect of the ultraviolet germicidal lamp 72 above, cleaner water can be discharged from the drain pipe 65, achieving a good purification operation of the wastewater.

[0069] It should be noted that the components in this application are all general standard parts or parts known to those skilled in the art, which effectively solve the technical problems raised in the background art.
