Description

Technical Field

[0001] The utility model relates to the technical field of oil fume waste gas treatment, in particular to an oil fume waste gas treatment device. Background Technique

[0002] A large amount of waste gas is generated during the production of oil. The waste gas contains oil and other pollutant particles. Therefore, the waste gas needs to be treated by treatment equipment before it can be discharged. Waste gas purification mainly refers to the work of treating industrial waste gas generated in industrial sites, such as dust particles, flue gas soot, odor gas, and toxic and harmful gases.

[0003] In the Chinese utility model patent with the publication number of CN211836982U, an exhaust gas treatment device for oil production is disclosed, including a filter box, characterized in that: the left end of the filter box is fixedly connected with a treatment box, the left end of the treatment box is provided with an air inlet, a water curtain device is fixedly installed inside the treatment box, the right end of the filter box is fixedly connected with a degassing box, the upper end of the degassing box is provided with an air outlet, and support columns are fixedly connected to the lower end of the filter box at equal intervals

[0004] In view of the above related technologies, the inventor believes that there are the following defects: the above device precipitates impurities in the waste gas through a water curtain. Subsequently, the waste gas is secondarily filtered through a filter screen. During this process, after the filter screen is used for a long time, a large amount of impurities will accumulate on the surface of the filter screen. At this time, if the filter screen is not replaced in time, it is easy to cause the filtering effect to decline. In the above device, the filter screen is fixedly connected to the inner wall of the filter box, which increases the difficulty for the staff to replace the filter screen, and thus increases the work difficulty of the staff. Content of the Utility Model

[0005] In order to solve the above problems, the utility model provides an oil fume waste gas treatment device.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: an oil fume waste gas treatment device, including a filter pipe, the filter pipe includes a first filter pipe, a connecting pipe installed on the side wall of the first filter pipe, and a second filter pipe installed on the side wall of the connecting pipe away from the first filter pipe. An air inlet is provided at one end of the first filter pipe away from the second filter pipe, an air outlet is provided at one end of the second filter pipe away from the first filter pipe, a water curtain device is installed inside the first filter pipe, activated carbon is provided inside the second filter pipe, a filter screen is provided inside the connecting pipe, and a connecting component for connecting with the first filter pipe and the second filter pipe is provided on the connecting pipe.

[0007] By adopting the above technical solution, when treating waste gas, the waste gas enters the filter pipe through the air inlet, and the particles in the waste gas are precipitated by the water curtain (the treatment of waste water is not the technical means solved by the present utility model, so it will not be shown and introduced in detail). Subsequently, the impurities in the gas are filtered by the filter screen and activated carbon, and the treated waste gas is further discharged through the air outlet. When the staff needs to replace the filter screen, the staff needs to close the connection component, remove the connecting pipe, and then replace the filter screen. After the replacement is completed, the staff can install the connecting pipe again to complete the replacement of the filter screen. In this process, the working difficulty of the staff is reduced.

[0008] Further, sliding grooves are symmetrically formed on two opposite side walls of the connecting pipe, mounting grooves are symmetrically formed on the side walls of the first filter pipe and the second filter pipe close to each other, the connecting component includes a plurality of sliding rods respectively slidably arranged in the plurality of sliding grooves and a plurality of threaded rods respectively threadedly connected to one ends of the plurality of sliding rods away from the mounting grooves, and the plurality of sliding rods are all slidably connected to the adjacent mounting grooves.

[0009] By adopting the above technical solution, when the staff needs to disassemble the connecting pipe, the staff needs to rotate the threaded rod, so that the sliding rod slides in the direction away from the mounting groove under the action of the threaded rod, so that the sliding rod is separated from the mounting groove. Subsequently, after the filter screen is replaced, the staff needs to align the sliding rod with the mounting groove. At this time, the staff rotates the threaded rod in the reverse direction, so that the sliding rod slides in the direction close to the mounting groove under the action of the threaded rod, so that one end of the sliding rod slides into the mounting groove, and then the connecting pipe is fixed to the first filter pipe and the second filter pipe. In this process, the walls of the first filter pipe and the second filter pipe are fixed to each other, and the probability that the first filter pipe and the second filter pipe shake and are separated from the connecting pipe will not occur.

[0010] Further, rotating grooves are respectively formed on the upper surface and the bottom surface of the connecting pipe, receiving grooves are formed on the inner walls of the two rotating grooves close to each other, the plurality of threaded rods respectively penetrate through the adjacent sliding grooves and extend into the adjacent receiving grooves, rotating rods are rotatably arranged in the two rotating grooves, first bevel gears are fixedly arranged on the side walls of the two rotating rods close to each other, second bevel gears are fixedly arranged on the side walls of the plurality of threaded rods away from the sliding rods, and the first bevel gears are meshed with the second bevel gears.

[0011] By adopting the above technical solution, when the staff needs to rotate the threaded rod, the staff needs to rotate the rotating rod, so that the first bevel gear rotates synchronously with the rotating rod under the action of the rotating rod, so that the second bevel gear rotates under the action of the first bevel gear, so that the threaded rod rotates under the action of the second bevel gear, so that the sliding rod slides under the action of the threaded rod, and the difficulty of the staff rotating the threaded rod is reduced, thereby reducing the working difficulty of the staff.

[0012] Furthermore, a fixing ring is fixedly arranged on the inner wall of the chute. The threaded rod penetrates through the fixing ring and is rotatably connected with the fixing ring. An annular groove is formed on the inner wall of the fixing ring, and an annular block is rotatably arranged in the annular groove. The annular block is fixed to the threaded rod.

[0013] By adopting the above technical solution, when the threaded rod rotates, the annular block rotates synchronously with the threaded rod under the action of the threaded rod. During this process, the side wall of the annular block abuts against the inner wall of the annular groove, thereby reducing the probability that the threaded rod follows the sliding rod and causes the second bevel gear and the first bevel gear to be separated from each other, thus improving the stability of the device.

[0014] Furthermore, first sealing grooves are formed on two opposite side walls of the connecting pipe, second sealing grooves are formed on the side walls of the first filter pipe and the second filter pipe close to each other, and a sealing device is commonly installed in the first sealing groove and the second sealing groove.

[0015] By adopting the above technical solution, the sealing device reduces the probability of leakage when treating waste gas, thus improving the sealing performance of the device.

[0016] Furthermore, a chamfer is formed at one end of the sliding rod away from the threaded rod.

[0017] By adopting the above technical solution, the chamfer reduces the difficulty of the sliding rod entering the installation groove, thus reducing the working difficulty of the staff.

[0018] Furthermore, adjusting knobs are fixedly arranged on the side walls of the two rotating rods away from each other.

[0019] By adopting the above technical solution, the adjusting knob reduces the difficulty of the staff rotating the rotating rod, thus reducing the working difficulty of the staff.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In this application, when treating waste gas, the waste gas enters the filter pipe through the air inlet, and the particles in the waste gas are precipitated by the water curtain (the treatment of waste water is not the technical means solved by the utility model, so it will not be shown and introduced in detail). Subsequently, the impurities in the gas are filtered by the filter screen and activated carbon, and the treated waste gas is discharged through the air outlet. When the staff needs to replace the filter screen, the staff needs to close the connecting component, remove the connecting pipe, and then replace the filter screen. After the replacement is completed, the staff can install the connecting pipe again to complete the replacement of the filter screen. During this process, the working difficulty of the staff is reduced;

[0022] 2. In this application, when the staff needs to disassemble the connecting pipe, the staff needs to rotate the threaded rod, so that the sliding rod slides away from the installation groove under the action of the threaded rod, so that the sliding rod is separated from the installation groove. Subsequently, when the filter screen is replaced, the staff needs to align the sliding rod with the installation groove. At this time, the staff rotates the threaded rod in the reverse direction, so that the sliding rod slides towards the installation groove under the action of the threaded rod, so that one end of the sliding rod slides into the installation groove, so that the connecting pipe is fixed to the first filter pipe and the second filter pipe. During this process, the walls of the first filter pipe and the second filter pipe are fixed to each other, so that the probability that the first filter pipe and the second filter pipe shake and are separated from the connecting pipe will not occur;

[0023] 3. In this application, when the staff needs to rotate the threaded rod, the staff needs to rotate the rotating rod, so that the first bevel gear rotates synchronously with the rotating rod under the action of the rotating rod, so that the second bevel gear rotates under the action of the first bevel gear, so that the threaded rod rotates under the action of the second bevel gear, so that the sliding rod slides under the action of the threaded rod, thereby reducing the difficulty for the staff to rotate the threaded rod, and thus reducing the work difficulty of the staff.

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0031] As Figures 1-5 shown, an oil fume waste gas treatment device disclosed in an embodiment of the present application includes a filter pipe 1, a water curtain device 16, activated carbon 17, a filter net 18, a connection assembly 3, a rotating rod 4, a first bevel gear 41, a second bevel gear 42, a fixing ring 5, and an annular block 51. The filter pipe 1 includes a first filter pipe 11, a connecting pipe 12, and a second filter pipe 13. The first filter pipe 11 is a rectangular tubular structure, the connecting pipe 12 is a rectangular tubular structure, and the connecting pipe 12 is installed on the side wall of the first filter pipe 11. The second filter pipe 13 is a rectangular tubular structure, and the second filter pipe 13 is installed on the side wall of the connecting pipe 12 away from the first filter pipe 11. An air inlet 14 is provided at one end of the first filter pipe 11 away from the second filter pipe 13, and an air outlet 15 is provided at one end of the second filter pipe 13 away from the first filter pipe 11. The water curtain device 16 is installed in the first filter pipe 11 for precipitating particles in the waste gas. The filter net 18 is arranged in the connecting pipe 12 for filtering impurities. The activated carbon 17 is arranged in the second filter pipe 13 for filtering.

[0032] When treating the waste gas, the waste gas enters the filter pipe 1 through the air inlet 14, and the particles in the waste gas are precipitated by the water curtain (the treatment of waste water is not the technical means solved by the present utility model, so it will not be shown and introduced in detail). Subsequently, the impurities in the gas are filtered by the filter net 18 and the activated carbon 17, and the treated waste gas is further discharged through the air outlet 15. When the staff needs to replace the filter net 18, the staff needs to close the connection assembly 3, remove the connecting pipe 12, and then replace the filter net 18. After the replacement is completed, the staff can install the connecting pipe 12 again to complete the replacement of the filter net 18. In this process, the working difficulty of the staff is reduced.

[0033] Chute grooves 2 are symmetrically formed on two opposite side walls of the connecting pipe 12, and mounting grooves 21 are symmetrically formed on side walls of the first filter pipe 11 and the second filter pipe 13 that are close to each other. A connecting assembly 3 is arranged on the connecting pipe 12 and is used for connecting with the first filter pipe 11 and the second filter pipe 13. The connecting assembly 3 includes slide rods 31 and threaded rods 32. The slide rods 31 are rectangular rod-shaped structures. There are multiple slide rods 31, which are respectively slidably arranged in multiple chute grooves 2, and multiple slide rods 31 are all slidably connected to the adjacent mounting grooves 21. There are multiple threaded rods 32, which are respectively threadedly connected to one ends of the multiple slide rods 31 away from the mounting grooves 21, and their axes are horizontal.

[0034] When the staff needs to disassemble the connecting pipe 12, the staff needs to rotate the threaded rod 32, so that the slide rod 31 slides away from the mounting groove 21 under the action of the threaded rod 32, thereby separating the slide rod 31 from the mounting groove 21. Subsequently, after the filter screen 18 is replaced, the staff needs to align the slide rod 31 with the mounting groove 21. At this time, the staff rotates the threaded rod 32 in the reverse direction, so that the slide rod 31 slides towards the mounting groove 21 under the action of the threaded rod 32, so that one end of the slide rod 31 slides into the mounting groove 21, thereby fixing the connecting pipe 12 to the first filter pipe 11 and the second filter pipe 13. During this process, the walls of the first filter pipe 11 and the second filter pipe 13 are fixed to each other, so that the probability that the first filter pipe 11 and the second filter pipe 13 shake and separate from the connecting pipe 12 will not occur.

[0035] Rotating grooves 22 are respectively formed on the upper surface and the bottom surface of the connecting pipe 12, and receiving grooves 23 are formed on inner walls of the two rotating grooves 22 that are close to each other. Multiple threaded rods 32 respectively penetrate through the adjacent chute grooves 2 and extend into the adjacent receiving grooves 23. The rotating rods 4 are circular rod-shaped structures, and their axes are vertical. There are two rotating rods 4, which are respectively rotatably arranged in the two rotating grooves 22. There are two first bevel gears 41, which are respectively fixedly arranged on side walls of the two rotating rods 4 that are close to each other, and their axes coincide with the axes of the rotating rods 4. There are multiple second bevel gears 42, which are respectively fixedly arranged on side walls of the multiple threaded rods 32 away from the slide rods 31, and their axes coincide with the axes of the threaded rods 32.

[0036] When the staff needs to rotate the threaded rod 32, the staff needs to rotate the rotating rod 4, so that the first bevel gear 41 rotates synchronously with the rotating rod 4 under the action of the rotating rod 4, so that the second bevel gear 42 rotates under the action of the first bevel gear 41, so that the threaded rod 32 rotates under the action of the second bevel gear 42, so that the slide rod 31 slides under the action of the threaded rod 32, thereby reducing the difficulty for the staff to rotate the threaded rod 32, and thus reducing the work difficulty of the staff.

[0037] The fixed ring 5 is a circular ring structure, and its axis coincides with the axis of the threaded rod 32. The fixed ring 5 is fixedly arranged on the inner wall of the sliding groove 2. The threaded rod 32 penetrates through the fixed ring 5 and is rotatably connected to the fixed ring 5. An annular groove 24 is formed on the inner wall of the fixed ring 5. The annular block 51 is a circular ring structure, and its axis coincides with the axis of the threaded rod 32. The annular block 51 is rotatably arranged in the annular groove 24, and the annular block 51 is fixedly connected to the threaded rod 32.

[0038] When the threaded rod 32 rotates, the annular block 51 synchronously rotates with the threaded rod 32 under the action of the threaded rod 32. During this process, the side wall of the annular block 51 abuts against the inner wall of the annular groove 24, thereby reducing the probability that the threaded rod 32 follows the sliding rod 31 and causes the second bevel gear 42 and the first bevel gear 41 to separate from each other, thus improving the stability of the device.

[0039] To improve the sealing performance of the device, first sealing grooves 25 are formed on two opposite side walls of the connecting pipe 12, and second sealing grooves 26 are formed on the side walls of the first filter pipe 11 and the second filter pipe 13 that are close to each other. A sealing device 6 is installed in both the first sealing groove 25 and the second sealing groove 26. The sealing device 6 reduces the probability of leakage during the treatment of waste gas, thereby improving the sealing performance of the device.

[0040] To reduce the working difficulty of the staff, a chamfer 7 is formed at one end of the sliding rod 31 away from the threaded rod 32. The chamfer 7 reduces the difficulty of the sliding rod 31 entering the installation groove 21, thereby reducing the working difficulty of the staff.

[0041] To reduce the working difficulty of the staff, adjusting knobs 8 are fixedly arranged on the side walls of the two rotating rods 4 that are away from each other. The adjusting knob 8 reduces the difficulty for the staff to rotate the rotating rod 4, thereby reducing the working difficulty of the staff.

[0042] The working principle of an oil fume waste gas treatment device in this embodiment is as follows: When treating waste gas, the waste gas enters the filter pipe 1 through the air inlet 14, and the particles in the waste gas are precipitated by the water curtain. Subsequently, the impurities in the gas are filtered through the filter net 18 and the activated carbon 17, and the treated waste gas is further discharged through the air outlet 15. When the staff needs to replace the filter net 18, the staff needs to close the connecting component 3, remove the connecting pipe 12, and then replace the filter net 18. After the replacement is completed, the staff can install the connecting pipe 12 again to complete the replacement of the filter net 18. During this process, the working difficulty of the staff is reduced.

[0043] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
