Description

Technical Field

[0001] The utility model belongs to the technical field of chemical waste gas treatment, and in particular relates to a chemical waste gas purification box. Background Art

[0002] Chemical waste gas refers to toxic and harmful gases discharged from chemical plants during chemical production. Chemical waste gas often contains many types of pollutants with complex physical and chemical properties and different toxicities, which seriously pollute the environment and affect human health. Therefore, the waste gas can only be discharged from the chemical plant after being purified by purification equipment.

[0003] The Chinese patent network CN217746398U discloses a chemical waste gas treatment, purification and environmental protection device, which includes a box body, one end of the box body is connected to an air inlet pipe, the other end of the box body is connected to an air outlet pipe, a processing component is arranged on the top of the box body, the processing component includes a spray box, a fixed frame, a filter plate and an activated carbon plate, the inner wall of the box body is respectively fixedly connected with the spray box and the fixed frame, the number of the fixed frames is provided with two, the filter plate and the activated carbon plate are respectively clamped inside the two fixed frames, the fixed frame includes a top plate, a through groove and a frame, the inner wall of the top plate is provided with a through groove, and the bottom of the top plate is fixedly connected with the frame.

[0004] In the prior art, when the nozzle sprays the purification liquid onto the flowing exhaust gas, some harmful substances in the exhaust gas will undergo chemical changes with the purification liquid and produce some solid impurities. These solid impurities fall directly to the bottom of the box under the influence of their own gravity. At the same time, the dust carried by the exhaust gas will also accumulate at the bottom of the box. As time goes by, the accumulated impurities and dust will increase. When cleaning the impurities and dust accumulated inside the box, the operator needs to dig them out, which makes the whole cleaning work inconvenient. At the same time, the purification liquid can only be in contact with the exhaust gas for a short time under the spraying of the nozzle, which makes the effect of purifying the exhaust gas by the purification liquid poor.

[0016] Furthermore, an air outlet pipe is fixedly connected to one side of the filter box, a water inlet pipe is fixedly connected to one side of the purification box, and a water outlet pipe is fixedly connected to the bottom of the purification box.

[0017] The utility model has the following beneficial effects:

[0018] 1. The industrial waste gas of the utility model can flow directly into the interior of the filter box under the guidance of the guide pipe. At the same time, the industrial waste water reacts with the industrial waste water that has infiltrated into the filter box. The solid impurities and dust generated at this time can directly fall into the interior of the filter box. The purified waste gas flows upward and flows through the air groove and the air pipe to the interior of the filter box for secondary purification. When it is necessary to clean the solid impurities and dust collected in the filter box, the hydraulic cylinder is directly started, so that the hydraulic cylinder drives the shielding plate to move upward through the connecting seat, and the shielding plate drives the sealing frame to move out of the sealing groove. With the continuous movement of the shielding plate, the guide pipe at the bottom of the shielding plate also moves out of the interior of the filter box.

Then the filter box is lifted upward by the handle, and the filter box is directly moved out from the interior of the purification box and the solid impurities and dust collected by the filter box are cleaned outside the purification box. The filter box can directly collect the solid impurities generated when the industrial waste gas reacts with the purification solution. At the same time, when cleaning the solid impurities collected inside the filter box, the shielding component can be automatically moved upward by the driving component, so that it is also convenient to lift the filter box out of the purification box. In summary, it is more convenient to clean the solid impurities generated by the reaction of industrial waste gas and purification solution.

[0019] 2. Under the guidance of the guide tube, the industrial waste gas of the utility model can flow directly to a deeper position of the purification liquid inside the purification box. At this time, the industrial waste gas can flow upward due to the different density between the industrial waste gas and the purification liquid. In this process, the industrial waste gas can better react with the purification liquid. At the same time, the pH sensor can monitor the purification liquid. When the overall effect of the purification liquid is not good, the pH value will change. At this time, the pH sensor can transmit a signal to the control panel, and the control panel controls the alarm light to start and use it to remind the staff, so that the invalid purification liquid can be replaced in time. In summary, the guide tube and the monitoring and warning component cooperate with each other to ensure the effect of the purification liquid in purifying industrial waste gas.

[0032] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0034] See also Figure 1-Figure 8 As shown, the utility model is a chemical waste gas purification box, including a purification box 1, the inner wall of the purification box 1 is fixedly connected with a support frame 2, the interior of the support frame 2 is movably connected with a filter assembly 3, the top of the purification box 1 is movably connected with a shielding assembly 4, the interior of the filter assembly 3 is provided with a guide tube 5, the top of the guide tube 5 passes through the shielding assembly 4 and is fixedly connected with a universal telescopic tube 6, one end of the universal telescopic tube 6 is fixedly connected with an air intake pipe 7, the air intake pipe 7 is fixedly installed on the outer surface of the purification box 1, a driving assembly 8 is fixedly installed on the outer side of the purification box 1, the output end of the driving assembly 8 is rotatably connected to the shielding assembly 4, and a monitoring and warning assembly 9 is fixedly installed on the outer surface of the purification box 1.

[0035] When purifying industrial waste gas, the purifying liquid is poured into the interior of the purification box 1, and then the industrial waste gas flows into the interior of the purification box 1 through the air intake pipe 7, the universal telescopic tube 6 and the guide tube 5. At this time, the purifying liquid reacts with the harmful substances in the industrial waste gas and makes the solid impurities generated by the reaction fall directly into the interior of the filter component 3. When it is necessary to clean the impurities collected in the filter component 3, the driving component 8 is directly driven, and the driving component 8 drives the shielding component 4 to move upward and does not block the top of the purification box 1. At this time, the filter component 3 can be directly lifted out from the interior of the purification box 1 and then the collected solid impurities can be cleaned outside the purification box 1.

[0036] The driving component 8 can drive the shielding component 4 to move upward and make the shielding component 4 no longer block the top of the purification box 1. This arrangement makes it more convenient to take out the filter component 3 from the inside of the purification box 1, and also makes it more convenient to clean the magazines collected inside the filter component 3; at the same time, the industrial waste gas can flow to the bottom of the purification box 1 under the guidance of the guide tube 5. At this time, the industrial waste gas can better contact with the purification liquid and get a full reaction. In addition, the monitoring and warning component 9 can monitor the pH value of the purification liquid, so that the staff can replace the expired purification liquid in time, thereby ensuring the effect of purifying the industrial waste gas by the purification liquid.

[0037] In one embodiment, for the above-mentioned filter assembly 3, the filter assembly 3 includes a connecting frame 301, the connecting frame 301 is arranged on the top of the supporting frame 2, the inner wall of the connecting frame 301 is fixedly connected with a filter box 302, the filter box 302 is movably connected to the supporting frame 2, and the top of the connecting frame 301 is fixedly connected with a handle 303.

[0038] The bottom end of the guide tube 5 is located inside the filter box 302, so that the solid impurities generated by the reaction between the industrial waste gas flowing out of the guide tube 5 and the purification liquid can directly fall into the inside of the filter box 302. When cleaning the solid impurities collected inside the filter box 302, the filter box 302 can be lifted out of the purification box 1 through the handle 303. The whole operation is relatively convenient. At the same time, the support frame 2 can support the filter box 302 through the connecting frame 301, and the support frame 2 can limit the filter box 302, so that the stability of the filter box 302 during operation can be guaranteed.

[0039] In one embodiment, for the above-mentioned shielding component 4, the shielding component 4 includes a shielding plate 401, and the shielding plate 401 is arranged on the top of the purification box 1. A sealing groove 402 is opened on the top of the purification box 1, and a sealing frame 403 is movably connected inside the sealing groove 402, and the sealing frame 403 is fixedly connected to the shielding plate 401.

[0040] When the baffle plate 401 is sealing and shielding the top of the purification box 1, the sealing frame 403 at the bottom of the baffle plate 401 can be directly moved to the inside of the sealing groove 402. The setting of the sealing groove 402 and the sealing frame 403 ensures the effect of the baffle plate 401 in sealing the purification box 1. At the same time, the baffle plate 401 can also be limited, so that the baffle plate 401 will not move around at will when sealing the purification box 1.

[0041] In one embodiment, for the above-mentioned driving component 8, the driving component 8 includes a hydraulic cylinder 801, and the hydraulic cylinder 801 is fixedly installed on one side of the purification box 1. The output end of the hydraulic cylinder 801 is fixedly connected with a connecting seat 802, and the connecting seat 802 is rotatably connected to the baffle plate 401.

[0042] When the filter box 302 is lifted out from the interior of the purification box 1, the hydraulic cylinder 801 is directly driven, so that the hydraulic cylinder 801 drives the baffle plate 401 to move upward through the connecting seat 802, and the baffle plate 401 drives the guide tube 5 to move out from the interior of the filter box 302. At the same time, the universal telescopic tube 6 begins to lengthen under the drive of the baffle plate 401. When the baffle plate 401 moves to a certain height, the baffle plate 401 is directly rotated so that the baffle plate 401 no longer blocks the top of the purification box 1. In summary, the setting of the hydraulic cylinder 801 makes it more convenient to remove the baffle plate 401 from the top of the purification box 1. At the same time, the baffle plate 401 can be rotated, so that the filter box 302 will not be blocked by the baffle plate 401 when it is lifted out from the interior of the purification box 1.

[0043] In addition, in a specific implementation, the upper corners of the connecting seat 802 close to the shielding plate 401 are rounded, and the lower corners are directly in contact with one side of the shielding plate 401. This setting ensures that when the shielding plate 401 is moved up and down, the shielding plate 401 will not rotate downward under the restriction of the connecting seat 802.

[0044] In one embodiment, for the above-mentioned monitoring and warning component 9, the monitoring and warning component 9 includes a pH sensor 901, the pH sensor 901 is fixedly installed on the inner wall of the purification box 1, a control panel 902 is fixedly installed on the outer surface of the purification box 1, the pH sensor 901 is electrically connected to the control panel 902, an alarm light 903 is fixedly installed on the outer surface of the purification box 1, and the alarm light 903 is electrically connected to the control panel 902.

[0045] The pH sensor 901 can monitor the pH value of the purification liquid inside the purification box 1. When the overall purification effect of the purification liquid is not good, the pH value of the purification liquid changes. At this time, the pH sensor 901 senses the change and transmits a signal to the control panel 902. At the same time, the control panel 902 can start the alarm light 903 to alarm and remind the staff, so that the staff can replace the purification liquid inside the purification box 1. The above-mentioned arrangement enables the purification liquid inside the purification box 1 to be replaced in time when it fails, so that the purification effect of purifying industrial waste gas by the purification liquid can be guaranteed.

[0046] In one embodiment, for the above-mentioned purification box 1, an air groove 10 is opened on the inner wall of the purification box 1, a filter box 11 is fixedly connected to one side of the purification box 1, an air pipe 12 is arranged inside the filter box 11, and the air pipe 12 is fixedly connected to the purification box 1, a positioning frame 13 is fixedly connected to the inner wall of the filter box 11, and an activated carbon plate 14 is arranged inside the positioning frame 13.

[0047] Since the density of industrial waste gas is different from the density of the entire purification liquid, the industrial waste gas inside the purification liquid can flow upward and directly flow out from the inside of the purification liquid after reacting with the purification liquid. The flowing waste gas can flow directly to the inside of the filter box 11 through the air groove 10 and the air pipe 12, so that the activated carbon plate 14 inside the filter box 11 performs secondary purification on the waste gas. The setting of the air pipe 12 prevents the waste gas flowing from the purification box 1 from accumulating on the top of the filter box 11, so that the activated carbon plate 14 as a whole can be fully utilized.

[0048] In one embodiment, for the above-mentioned filter box 11, a placement groove 15 is opened on the top of the filter box 11, a through groove 16 is opened at the bottom of the placement groove 15, and a mounting frame 17 is movably connected inside the through groove 16, and the mounting frame 17 is movably connected to the positioning frame 13. A mounting groove 18 is opened on one side of the mounting frame 17, and the activated carbon plate 14 is movably connected to the mounting groove 18. A magnetic groove 19 is opened at the bottom of the inner wall of the placement groove 15, and a magnet frame 20 is movably connected inside the magnetic groove 19. A placement plate 21 is fixedly connected to the top of the magnet frame 20, and the placement plate 21 is movably connected to the placement groove 15.

[0049] When replacing the activated carbon plate 14, the placement plate 21 is directly lifted upward, and the placement plate 21 is moved out from the inside of the placement groove 15, and the magnet frame 20 is moved out from the inside of the magnetic groove 19. At the same time, the mounting frame 17 is moved inside the positioning frame 13 driven by the placement plate 21. When the mounting frame 17 is completely moved out of the inside of the filter box 11, the activated carbon plate 14 is directly pushed to move the activated carbon plate 14 out from the inside of the mounting groove 18, and then the new activated carbon plate 14 is moved into the mounting groove 18, and then the mounting frame 17 is moved into the inside of the filter box 11. In summary, the arrangement of the magnetic groove 19 and the magnet frame 20 allows the two to be adsorbed together when the magnet frame 20 moves to the inside of the magnetic groove 19, so that the placement plate 21 will not move out from the inside of the placement groove 15 without the influence of a large external force, and at the same time, the stability of the mounting frame 17 when supporting the activated carbon plate 14 can be guaranteed, and the arrangement of the magnetic groove 19 and the magnet frame 20 can also play a certain sealing role.

[0050] In one embodiment, for the filter box 11 , an air outlet pipe 22 is fixedly connected to one side of the filter box 11 , an inlet pipe 23 is fixedly connected to one side of the purification box 1 , and a water outlet pipe 24 is fixedly connected to the bottom of the purification box 1 .

[0051] After completing secondary purification inside the filter box 11, the industrial waste gas can flow out directly through the air outlet pipe 22. When the purification liquid inside the purification box 1 needs to be replaced, the water outlet pipe 24 can be directly opened to allow the ineffective purification liquid inside the purification box 1 to flow out. During this process, the operator can also clean the solid impurities collected inside the filter box 302. When the ineffective purification liquid is discharged, the new purification liquid is poured into the interior of the purification box 1 through the water inlet pipe 23. The whole operation is relatively convenient.

[0052] Through the above technical solution, 1. The industrial waste gas can flow directly into the interior of the filter box 302 under the guidance of the guide pipe 5. At the same time, the industrial waste water reacts with the industrial waste water that has penetrated into the interior of the filter box 302. The solid impurities and dust generated at this time can directly fall into the interior of the filter box 302. The purified waste gas flows upward and flows through the air groove 10 and the air pipe 12 to the interior of the filter box 11 for secondary purification. When it is necessary to clean the solid impurities and dust collected in the filter box 302, the hydraulic cylinder 801 is directly started, so that the hydraulic cylinder 801 drives the baffle 401 to move upward through the connecting seat 802. The shielding plate 401 drives the sealing frame 403 to move out from the inside of the sealing groove 402. As the shielding plate 401 continues to move, the guide tube 5 at the bottom of the shielding plate 401 also moves out from the inside of the filter box 302. When the shielding plate 401 moves, the universal telescopic tube 6 extends. When the shielding plate 401 moves to a suitable height, the shielding plate 401 is directly rotated upward so that the shielding plate 401 no longer blocks the top of the purification box 1. Then, the filter box 302 is lifted upward by the handle 303, so that the filter box 302 is directly moved out of the purification box 1 and the filter box 302 collects the filter outside the purification box 1. 1. The solid impurities and dust generated by the reaction of industrial waste gas with the purification liquid can be cleaned. The filter box 302 can directly collect the solid impurities generated when the industrial waste gas reacts with the purification liquid. At the same time, when cleaning the solid impurities collected inside the filter box 302, the shielding component 4 can be automatically moved upward by the driving component 8, so that it is also convenient to lift the filter box 302 out of the purification box 1. In summary, it is convenient to clean the solid impurities generated by the reaction of industrial waste gas with the purification liquid; 2. The industrial waste gas can flow directly to the deeper position of the purification liquid inside the purification box 1 under the guidance of the guide pipe 5. At this time, the industrial waste gas is Different from the density of the purification liquid, it can flow upward. In this process, the industrial waste gas can better react with the purification liquid. At the same time, the pH sensor 901 can monitor the purification liquid. When the overall effect of the purification liquid is not good, the pH value will change. At this time, the pH sensor 901 can transmit a signal to the control panel 902, and the control panel 902 controls the alarm light 903 to start and remind the staff, so that the invalid purification liquid can be replaced in time. In summary, the guide tube 5 and the monitoring and warning component 9 cooperate with each other to ensure the effect of the purification liquid in purifying industrial waste gas.
