Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and particularly to a filtering and treatment device for organic waste gas treatment. Background Art

[0002] Organic waste gas generally has the characteristics of being flammable, explosive, toxic, harmful, insoluble in water, soluble in organic solvents, and difficult to treat. If directly discharged, it will cause serious pollution to the environment. Therefore, it is necessary to reasonably treat the waste gas containing organic gas before discharging. Organic waste gas treatment refers to the treatment work of adsorbing, filtering, and purifying the organic waste gas generated in the industrial production process. At present, when treating the waste gas containing organic gas, the commonly used methods include activated carbon adsorption treatment method, catalytic combustion method, catalytic oxidation method, etc. When using activated carbon adsorption treatment, since general organic waste gas will contain dust and other particulate impurities at the same time, in order to avoid blocking the activated carbon component, impurity pre-filtering treatment will be carried out on the waste gas before activated carbon adsorption to intercept most of the dust and other particulate impurities.

[0003] However, when the device for treating organic waste gas by means of activated carbon adsorption in the prior art is in use, it is impossible to conveniently clean the surface of the component provided for filtering dust and particulate impurities in the organic waste gas, which easily causes the surface of the dust and particulate impurity filtering component to have a low permeability due to excessive accumulation of dust and impurities in a short period of time, thereby affecting its service life.

[0004] Therefore, it is necessary to provide a filtering and treatment device for organic waste gas treatment to solve the above technical problems. Summary of the Invention

Specific embodiments

[0041] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0042] The first embodiment

[0043] Please refer to Figures 1 - 10, in the first embodiment of the present invention, the filtration treatment device for organic waste gas treatment includes: a bracket 1, on the top of the bracket 1, a filtration box 2, a front filtration cylinder 3 and an exhaust fan 5 are fixedly installed. Inside the filtration box 2, there are multiple activated carbon filter plates 6, and the activated carbon filter plates 6 are used to adsorb the organic gases in the waste gas. On the top of the front filtration cylinder 3, a connecting pipe 4 is fixedly installed, and one end of the connecting pipe 4 away from the front filtration cylinder 3 is fixedly connected to the filtration box 2. Inside the front filtration cylinder 3, there are multiple impurity removal filter elements 9 for pre-filtering the waste gas, aiming to intercept the dust and other particulate impurities in the waste gas. The air inlet of the exhaust fan 5 is fixedly connected to the side of the filtration box 2 away from the front filtration cylinder 3. An air inlet pipe 7 is also fixedly installed on the outer wall of the front filtration cylinder 3, and it is connected to the waste gas discharge pipe through the air inlet pipe 7, so that the waste gas can sequentially pass through the front filtration cylinder 3 and the filtration box 2 under the pumping of the exhaust fan 5. A partition 8 is fixedly installed inside the front filtration cylinder 3. A sealing groove is opened at the bottom of the partition 8, and an air passing opening is opened on the top inner wall of the sealing groove. A bottom sealing plate 10 is installed inside the front filtration cylinder 3. On the top of the bottom sealing plate 10, multiple rotating shafts 13 are rotatably installed. At the top ends of the multiple rotating shafts 13, positioning round seats 14 are rotatably sleeved respectively. The multiple impurity removal filter elements 9 are respectively installed on the multiple positioning round seats 14. The tops of the multiple impurity removal filter elements 9 are all located in the corresponding sealing grooves. Multiple stirring rods 18 are fixedly installed on the rotating shafts 13, and the stirring rods 18 are in contact with the surfaces of the corresponding impurity removal filter elements 9. The multiple stirring rods 18 are used to clean the sundries attached to the surfaces of the impurity removal filter elements 9. During the rotation of the rotating shafts 13, the multiple stirring rods 18 on them rotate, and the stirring rods 18 will brush off the dust on the surfaces of the impurity removal filter elements 9 during rotation. Multiple external gears 15 are fixedly sleeved on the multiple rotating shafts 13. At the central position of the bottom sealing plate 10, a central rotating rod 16 is penetrated and rotatably installed. An internal gear 17 is fixedly sleeved at the top end of the central rotating rod 16. The multiple external gears 15 are all meshed with the internal gear 17. When the internal gear 17 is rotated by the central rotating rod 16, the internal gear 17 can drive the multiple external gears 15 to rotate, and then the multiple rotating shafts 13 rotate simultaneously. A collection groove 1001 is opened on the top of the bottom sealing plate 10, and the collection groove 1001 is used to collect dust and other particulate impurities.

[0044] In this embodiment, in order to protect the external gear 15 and the internal gear 17 from dust, a protective cover 12 is fixedly installed on the top of the bottom sealing plate 10. The multiple external gears 15 and the internal gear 17 are all located inside the protective cover 12. The protective cover 12 is composed of a circular enclosure and a conical cover. The conical cover is fixedly installed on the top of the circular enclosure. The multiple rotating shafts 13 all penetrate the conical cover and are rotationally and sealingly connected to the conical cover. The conical cover is beneficial for part of the dust and other impurities to roll into the collection groove 1001.

[0045] In this embodiment, the impurity removal filter element 9 specifically includes a porous tube 901, a docking head 902, a base 903, and a filter cotton sleeve 904. The docking head 902 is fixedly installed at the top of the porous tube 901, the base 903 is fixedly installed at the bottom of the porous tube 901, and the filter cotton sleeve 904 is fixedly sleeved on the porous tube 901. In order to increase the sealing degree of the docking between the impurity removal filter element 9 and the partition plate 8, first sealing gaskets are fixedly installed on the top inner walls of a plurality of sealing grooves. The first sealing gaskets are made of silica gel. The tops of a plurality of docking heads 902 all extend into the corresponding sealing grooves and are in contact with the corresponding first sealing gaskets. A positioning groove 9031 is formed in the bottom of the base 903. The tops of a plurality of positioning round seats 14 all extend into the corresponding positioning grooves 9031 and are in contact with the top inner walls of the corresponding positioning grooves 9031. When installing the impurity removal filter element 9, the impurity removal filter element 9 is sleeved on the positioning round seat 14 through the positioning groove 9031. In this way, when the bottom sealing plate 10 enters the front filter cylinder 3, a plurality of impurity removal filter elements 9 can be longitudinally aligned with a plurality of sealing grooves. Pushing the bottom sealing plate 10 upward can make the docking heads 902 at the tops of a plurality of impurity removal filter elements 9 enter the sealing grooves. In this embodiment, in order to increase the filtering area on the outer surface of the impurity removal filter element 9, a plurality of vertically distributed vertical protrusions 9041 are integrally formed on the outer wall of the filter cotton sleeve 904. Arc-shaped grooves are formed on both sides of the vertical protrusions 9041. A channel is formed between any two adjacent vertical protrusions 9041. A plurality of dial rods 18 are all located in the corresponding channels. When the dial rods 18 rotate, they will sequentially sweep across a plurality of vertical protrusions 9041, and the vertical protrusions 9041 will have a compression process. After the dial rods 18 leave the vertical protrusions 9041, due to the previous compression, there will be a subsequent rebound process. In this way, part of the dust embedded in the surface layer of the vertical protrusions 9041 can also be ejected. In addition, a servo motor or other power elements can be arranged at the bottom of the bottom sealing plate 10 to drive the central rotating rod 16 to rotate a certain number of turns regularly to complete the cleaning work on the surface of the impurity removal filter element 9.

[0046] In this embodiment, in order to ensure the sealing degree between the bottom sealing plate 10 and the front filter cylinder 3, a fixing ring 11 is fixedly installed on the inner wall of the front filter cylinder 3. A second sealing gasket is fixedly installed at the bottom of the fixing ring 11. The top of the bottom sealing plate 10 is in contact with the second sealing gasket.

[0047] In this embodiment, in order to facilitate the installation of the bottom sealing plate 10 and the multiple impurity removal filter elements 9, a vertical seat is fixedly installed on one side of the bracket 1 close to the front filter cylinder 3. An elevating carrier plate 19 is slidably sleeved on the vertical seat. Specifically, limiting slideways are opened on both sides of the vertical seat. Two limiting sliders are fixed on the elevating carrier plate 19. One ends of the two limiting sliders close to each other both extend into the corresponding limiting slideways and are slidably connected with the inner walls of the corresponding limiting slideways. A plurality of positioning slots 1901 are opened at the top of the elevating carrier plate 19. A plurality of positioning insertion rods 21 are fixedly installed at the bottom of the bottom sealing plate 10, and the positioning insertion rods 21 are adapted to the positioning slots 1901. A handle is welded on the elevating carrier plate 19. During use, first insert the plurality of positioning insertion rods 21 into the corresponding positioning slots 1901, so that the bottom sealing plate 10 can be axially aligned with the front filter cylinder 3. Correspondingly, the plurality of positioning round seats 14 and the corresponding sealing grooves can also be axially aligned. Then, sleeve the impurity removal filter elements 9 on the positioning round seats 14. After the impurity removal filter elements 9 are sleeved, they can be automatically axially aligned with the corresponding sealing grooves. After that, just lift the elevating carrier plate 19 upward, and the bottom sealing plate 10 can smoothly enter the front filter cylinder 3, and the tops of the plurality of impurity removal filter elements 9 can also enter the corresponding sealing grooves.

[0048] In this embodiment, the bottom sealing plate 10 is fixed on the front filter cylinder 3 by nuts. Specifically, a plurality of screw rods are fixedly installed at the bottom of the front filter cylinder 3. A plurality of L-shaped fixing feet 20 are fixedly installed at the bottom of the bottom sealing plate 10. The plurality of screw rods respectively penetrate through the plurality of L-shaped fixing feet 20 and are respectively movably connected with the plurality of L-shaped fixing feet 20. Nuts are threadedly sleeved on the plurality of screw rods.

[0049] In this embodiment:

[0050] During use, the air inlet pipe 7 is externally connected to an exhaust gas discharge pipe. After starting the operation of the exhaust fan 5, the exhaust gas is drawn into the front filter cylinder 3 through the air inlet pipe 7, and then sequentially enters the filter box 2 through the connecting pipe 4. Before the exhaust gas enters the connecting pipe 4, it needs to pass through the filter cotton sleeve 904 on the impurity removal filter element 9, and the dust and other particulate impurities carried in the exhaust gas will be intercepted, which greatly reduces the particulate impurities in the exhaust gas entering the filter box 2, so as to avoid the blockage of the activated carbon filter plate 6. After the exhaust gas filtered in advance enters the filter box 2, it needs to sequentially pass through a plurality of activated carbon filter plates 6, and the organic gas in the exhaust gas will be adsorbed by the micropores on the activated carbon filter plates 6. Finally, the exhaust gas filtered twice is discharged through the air outlet of the exhaust fan 5;

[0051] Since the surface of the filter cotton sleeve 904 has a plurality of vertical ridges 9041, the filtration area is relatively larger. After the impurity removal filter element 9 has been used for a certain period of time, a large amount of dust and other particulate impurities will adhere to its surface, thereby affecting the permeability of the impurity removal filter element 9. In this case, the central rotating rod 16 can be rotated to clean the surface of the impurity removal filter element 9 to extend its service life. During the rotation of the central rotating rod 16, the internal gear 17 will be driven to rotate, and during the rotation of the internal gear 17, a plurality of external gears 15 will be driven to rotate, so that a plurality of rotating shafts 13 will rotate. The rotating shaft 13 drives a plurality of lever rods 18 on itself to rotate. Since the docking head 902 at the top of the impurity removal filter element 9 abuts against the first sealing gasket in the sealing groove and the static friction force received is relatively large, the impurity removal filter element 9 will not rotate during the rotation of the rotating shaft 13. In this way, a relative rotation will occur between the plurality of lever rods 18 and the corresponding impurity removal filter element 9. During the rotation of the lever rod 18, it will sequentially sweep over the vertical ridges 9041 on the filter cotton sleeve 904, so that the dust and other particulate impurities adhering to the surface of the filter cotton sleeve 904 will be shaken off. At the same time, during the process that the lever rod 18 sweeps over the vertical ridges 9041, the vertical ridges 9041 will have a process of being compressed first and then released and rebounding, and part of the dust embedded in the surface layer of the vertical ridges 904 can also be ejected. In this way, after rotating the central rotating rod 16 clockwise several times and then counterclockwise several times, the cleaning work of the dust and impurities on the surface of the impurity removal filter element 9 can be better completed;

[0052] When there is a relatively large amount of dust and impurities embedded in the impurity removal filter element 9, its permeability will become very poor, and cleaning the outer surface through the lever rod 18 can no longer improve the situation. In this case, it is necessary to replace the filter cotton sleeve 904 on the impurity removal filter element 9. When replacing, first lift the lifting carrier plate 19 upward until the bottom ends of the plurality of positioning insertion rods 21 enter the corresponding positioning slots 1901, and then sequentially remove the nuts on the plurality of screw rods. In this way, the plurality of L-shaped fixing feet 20 will lose their restraint. After that, slowly lower the lifting carrier plate 19. Under the action of gravity, components such as the bottom sealing plate 10 and the impurity removal filter element 9 will all move downward along with the lifting carrier plate 19, and finally move outside the front filter cylinder 3. After the lifting carrier plate 19 is lowered to the lowest position, the impurity removal filter elements 9 on the positioning round seat 14 can be taken away one by one, and at the same time, the dust and particulate impurities collected in the collection tank 1001 can also be cleaned. After replacing the new filter cotton sleeve 904, the installation work of the bottom sealing plate 10 and the plurality of impurity removal filter elements 9 can be completed by operating in the reverse of the above working principle.

[0053] Compared with the related technology, the filtering and treatment device for organic waste gas treatment provided by the present invention has the following beneficial effects:

[0054] The outer surface of the impurity removal filter element 9 is provided with a plurality of vertical ridges 9041, and channels are formed between any two vertical ridges 9041, so that the filtration area of the impurity removal filter element 9 can be significantly increased, which is beneficial to reducing the initial resistance of the impurity removal filter element 9 and improving its service life; through the settings of the bottom sealing plate 10, a plurality of rotating shafts 13, a plurality of positioning circular seats 14, a plurality of external gears 15, a central rotating rod 16, an internal gear 17, and a plurality of shifting rods 18, during use, after rotating the central rotating rod 16, a plurality of rotating shafts 13 can be driven to rotate. During the rotation of the rotating shafts 13, a plurality of shifting rods 18 on themselves will be driven to rotate, and during the rotation of the shifting rods 18, the dust and impurities attached to the surface of the impurity removal filter element 9 can be shaken off, so that the permeability of the impurity removal filter element 9 can be restored to a certain extent, and the service life of the impurity removal filter element 9 can be further extended. The surface of the impurity removal filter element 9 can be cleaned without disassembling it, and the operation is simple; through the settings of the lifting carrier plate 19, a plurality of positioning insertion rods 21, vertical seats and other components, it is convenient to automatically align the impurity removal filter element 9 with the sealing groove on the partition plate 8 when installing the impurity removal filter element 9, and at the same time, components such as the bottom sealing plate 10 and the impurity removal filter element 9 can be stably supported, which is beneficial to improving the installation efficiency of the impurity removal filter element 9 and the bottom sealing plate 10.
