Description

Technical Field

[0001] The present invention relates to the technical field of dust removal and desulfurization equipment, and specifically provides an environment-friendly dust removal and desulfurization equipment. Background Art

[0002] During the production process of existing industries, a large amount of waste gas is generated. These waste gases contain various harmful components, among which sulfur-containing substances have a great impact on the air. Directly discharging them into the atmosphere will seriously affect the atmospheric environment and then cause harm to the human body. Therefore, existing industrial waste gases are treated by dust removal and desulfurization equipment before being discharged. Existing dust removal and desulfurization equipment operates by discharging the gas into the equipment and then spraying liquid through a spraying device for dust removal and desulfurization of the gas. However, there are still some problems in the use of existing dust removal and desulfurization equipment, which are specifically as follows:

[0003] When existing dust removal and desulfurization equipment is in use, a liquid storage area is formed at the bottom inside the equipment, and there is an exhaust gas inlet above. When the exhaust gas enters this area, the liquid sprayed from above is used to sediment and collect it, and then it is pumped out again by a reflux pump and sprayed from the top for continuous recycling. In this way, the dust and impurities mixed in the bottom liquid cannot be well separated, resulting in damage to the circulation pump. At the same time, the increasingly turbid treatment liquid will also cause the treatment effect to gradually decrease. Finally, there will be too much dirt and impurities inside the equipment, requiring frequent shutdown for maintenance. This not only reduces the use efficiency of the equipment but also cannot guarantee the treatment effect of the equipment on the waste gas. Therefore, we propose an environment-friendly dust removal and desulfurization equipment. Summary of the Invention

All other implementation manners obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0034] Please refer to Figures 1-5An environmentally friendly dust removal and desulfurization device comprises an outer cylinder 1, a separation cylinder 2 is fixedly installed at the bottom end of the inner part of the outer cylinder 1, a shielding ring 3 is fixedly installed at the top of the separation cylinder 2 inside the outer cylinder 1, a filter assembly 4 is movably installed inside the separation cylinder 2, an external drive motor 5 is fixedly installed at the top end of the outer drive motor 5, a driving rod 6 is fixedly installed at the bottom end of the external drive motor 5, a spray assembly 7 is fixedly installed in the middle of the driving rod 6, a top cover 8 is fixedly installed in the middle of the inner part of the outer cylinder 1, a water inlet center pipe 9 is fixedly installed at the top of the top cover 8, and the outer cylinder 1 A supporting base 10 is fixedly installed in the middle of the inner part, a stirring wheel 11 is fixedly installed at the bottom end of the driving rod 6, an air inlet pipe 12 is fixedly installed inside the outer cylinder 1, a support rod 13 is fixedly installed outside the air inlet pipe 12, a collecting assembly 14 is sleeved and fixedly installed on the support rod 13, an air outlet assembly 15 is fixedly installed in an annular shape at the bottom end of the air inlet pipe 12, a circulating pump 16 is arranged outside the outer cylinder 1, circulating pipes 17 are fixedly installed at both ends of the circulating pump 16, and an electric telescopic rod 18 is fixedly installed at the top of the outer cylinder 1;

[0035] Compared with the prior art, the present application provides a separation cylinder 2 at the bottom end of the outer cylinder 1, and uses the separation cylinder 2 to divide the interior into two parts, the inner part is an impurity separation and collection area, and the outer part is a clean circulating liquid flow area. The inner part is driven by the rotation of the stirring wheel 11 at the bottom to rotate the liquid and impurities therein to generate centrifugal force. Under the action of the centrifugal force, the internal liquid and the impurities therein are driven to rotate together and adhere to the inside of the filter ring net 43 on the side, so that the impurities are separated, and the liquid can flow through the filter ring net 43 to the outside of the separation cylinder 2 for subsequent circulation. In this way, the cleanliness of the circulating liquid can not only protect the service life of the circulating pump 16, but also avoid the accumulation of dirt inside the entire equipment due to the spraying of dirty liquid, and can also ensure that the sprayed liquid is free from dust in industrial waste gas. Impurities are effectively adsorbed and separated to improve the gas treatment effect. At the same time, a support rod 13 is arranged in a ring on the bottom side of the air inlet pipe 12, and the support rod 13 is arranged inside the separation cylinder 2. In this way, the exhaust gas can be discharged from the internal area of ​​the separation cylinder 2, and the crystallinity of the liquid outside the separation cylinder 2 can be guaranteed. At the same time, the matching arrangement of the limit rotating block 147 and the resistance block 45 is utilized so that the filter ring net 43 will compress the collection component 14 as a whole toward the middle during the upward movement. When the upward process is completed and the downward movement is completed, the scraping groove 141 is utilized to scrape and separate the dust and impurities accumulated on the inside of the filter ring net 43, and after scraping, the dust and impurities can enter the collection groove 142 for collection. This not only can realize regular equipment self-cleaning and ensure the use effect of the equipment, but also can extend the maintenance cycle, reduce the maintenance frequency, and ensure the use efficiency of the equipment.

[0036] See also Figures 1-3, An environmentally friendly dust removal and desulfurization device, including a shielding ring 3. The shielding ring 3 is composed of two parts. One part is arranged on the outer side of the top end of the separation cylinder 2, and the other part is arranged on the inner side of the top end of the separation cylinder 2. A structure with a high outer side and a low middle part is formed between the two parts of the separation cylinder 2, and the range covered by the inner diameter wraps the collection component 14;

[0037] In this embodiment, it should be noted that this can ensure that the liquid sprayed from above flows and accumulates towards the middle after contacting the upper surface of the shielding ring 3, thereby ensuring that the sewage mixed with dust and impurities is concentrated in the middle part of the separation cylinder 2 for separation treatment, and ensuring the use effect of the device.

[0038] Please refer to Figures 1-4 , An environmentally friendly dust removal and desulfurization device, including a top cover 8 and an inlet central pipe 9. The top cover 8 and the inlet central pipe 9 are movably arranged outside the driving rod 6, and the spraying component 7 is fixedly connected outside the driving rod 6 through a short rod. The stirring wheel 11 is movably arranged at the bottom of the middle area wrapped by the separation cylinder 2 and is attached to the inner surface of the bottom end of the outer cylinder 1;

[0039] In this embodiment, it should be noted that this can drive the spraying component 7 to rotate by the rotation of the driving rod 6, thereby realizing the full and sufficient spraying and dust removal and desulfurization effect on the upward flowing gas inside the outer cylinder 1. At the same time, combined with the rotation of the stirring wheel 11 at the bottom, the liquid mixed with dust and impurities gathered in the middle area of the separation cylinder 2 is stirred, and then under the action of the generated centrifugal force, the dust and impurities are continuously piled up and filtered on the filter component 4 for collection, so as to ensure that there is enough clean liquid outside the separation cylinder 2 for recycling, and ensure the sustainable usability of the device.

[0040] Please refer to Figures 1-3 , An environmentally friendly dust removal and desulfurization device, including an electric telescopic rod 18. The electric telescopic rod 18 is fixedly installed below the filter component 4 at the top of the outer cylinder 1. The bottom of the filter component 4 is inserted and movably connected in the separation cylinder 2; the intake pipe 12 is an L-shaped structure and the height of its vertical direction is greater than the height that the filter component 4 can move up;

[0041] In this embodiment, it should be noted that this can achieve scraping off the impurities piled up and filtered on the filter component 4 by the collection component 14 during the up and down movement of the filter component 4, thereby ensuring the permeability of the filter component 4 and ensuring the continuous use effect of the device.

[0042] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 10, An environment-friendly dust removal and desulfurization device, including a filtering component 4. The filtering component 4 includes a top ring 41. A long rod 42 is fixedly installed at the bottom end of the top ring 41. A filtering ring net 43 is fixedly installed at the bottom end of the long rod 42. A bottom ring 44 is fixedly installed at the bottom end of the filtering ring net 43. A contact block 45 is fixedly installed on the upper surface of the bottom ring 44 in a ring-shaped and uniform manner.

[0043] In this embodiment, it should be noted that the top end of the electric telescopic rod 18 is fixedly installed on the lower surface of the top ring 41. A hollow groove is opened on the separation cylinder 2. A mesh hole is opened on the filtering ring net 43 at the position of the hollow groove of the separation cylinder 2. The inner diameter of the bottom ring 44 is smaller than the inner diameter of the filtering ring net 43 and the outer diameter is equal to the outer diameter of the filtering ring net 43. The contact block 45 is fixedly installed on the upper surface of the bottom ring 44 inside the filtering ring net 43. The side of the contact block 45 close to the center of the long rod 42 is a bevel structure. In this way, the centrifugal force generated by the rotation of the stirring wheel 11 can be used to rotate the dust and impurities to the filtering ring net 43 for centralized accumulation and collection. And under the drive of the electric telescopic rod 18, the filtering ring net 43 can move up and down, and then with the existence of the collection component 14, the dust and impurities accumulated on the surface of the filtering ring net 43 can be scraped and cleaned to ensure the permeability of the filtering ring net 43, and then ensure the continuous use of the device.

[0044] Please refer to Figures 1-4 , An environment-friendly dust removal and desulfurization device, including a spraying component 7. The spraying component 7 includes an intermediate ring cylinder 71. A plurality of branch pipes 72 are fixedly installed on the side of the intermediate ring cylinder 71 in a uniform manner. A spraying head 73 is fixedly installed at the bottom end of the branch pipe 72.

[0045] In this embodiment, it should be noted that the inside of the intermediate ring cylinder 71 is fixedly connected to the driving rod 6 through a short rod. The spraying head 73 is provided with double-layer misaligned nozzles. The intermediate ring cylinder 71 is rotatably arranged between the top cover 8 and the supporting base 10. One end of the circulating pipeline 17 is hermetically connected to the water inlet central pipe 9 in a penetrating manner. In this way, it can be ensured that the sprayed water combined with the rotatable intermediate ring cylinder 71 can completely cover the flow of the gas flow channel in the outer cylinder 1, and then ensure that the impurities in the gas can be more fully separated and removed.

[0046] Please refer to Figures 2-7 , An environment-friendly dust removal and desulfurization device, including a collection component 14. The collection component 14 includes a scraping groove 141. A collection groove 142 is fixedly installed at the bottom end of the scraping groove 141. A telescopic sleeve rod 143 is fixedly installed on one side of the scraping groove 141. A cross plate 144 is fixedly installed at the end of the telescopic sleeve rod 143. A first spring 145 is fixedly installed on one side of the scraping groove 141. A locking pin rod 146 is inserted and movably installed on the cross plate 144. A limiting rotating block 147 is movably installed on the other side of the scraping groove 141.

[0047] In this embodiment, it should be noted that a straight groove penetrating the upper and lower ends is formed in the middle of the other side of the scraping groove 141, and the position of this straight groove corresponds to the position of the abutting block 45. The collecting groove 142 is fixedly connected to the lower part of the scraping groove 141 on the side where the telescopic sleeve rod 143 is located and communicates with the inside of the scraping groove 141. The other end of the first spring 145 is fixedly installed on the cross plate 144. A circular groove is formed at the end of the support rod 13. The cross plate 144 is clamped at the end of the support rod 13. The locking pin rod 146 penetrates the cross plate 144 and is inserted and limited in the circular groove at the end of the support rod 13. The limiting rotating block 147 is set for one-way downward rotation limit. In this way, during the upward movement of the abutting block 45, it will abut against the side surface of the limiting rotating block 147, and then the scraping groove 141 will continuously compress the first spring 145 until the abutting block 45 completely moves upward beyond the limiting rotating block 147 and then rebounds under the action of the first spring 145. In this way, the edge of the scraping groove 141 can be attached to the surface of the filter ring net 43, and then the dust and impurities adhered to its surface can be scraped off during the downward movement, realizing the self-cleaning effect of the device. And with the storage capacity of the collecting groove 142, the maintenance cycle of the device can be greatly extended, thereby improving the use efficiency of the device.

[0048] Please refer to Figures 2-8 , an environment-friendly dust removal and desulfurization device, including an air outlet assembly 15. The air outlet assembly 15 includes an air outlet pipe 151. Two horizontal positioning plates 152 are fixedly installed on both sides inside the air outlet pipe 151. An air outlet groove 153 is formed at the bottom end of the air outlet pipe 151. A movable opening and closing assembly 154 is movably connected to the horizontal positioning plate 152;

[0049] In this embodiment, it should be noted that the inside of the air outlet pipe 151 is connected to the inside of the intake pipe 12 in a through manner. A groove is formed between the two horizontal positioning plates 152. The air outlet pipe 151 is arranged at the bottom end inside the separation cylinder 2 and in the liquid. In this way, the air pressure generated by the input gas inside the air outlet pipe 151 can be used to push the movable opening and closing assembly 154 to move, and then open the air outlet groove 153 so that the gas is ejected into the liquid remaining below, thereby realizing the preliminary filtering and separation of dust and impurities and improving the treatment effect on the gas. And when it is necessary to stop the machine, while the gas pressure gradually decreases, the movable opening and closing assembly 154 will also automatically close, thereby avoiding liquid backflow and ensuring the service life of the device.

[0050] Please refer to Figures 8-9 , an environment-friendly dust removal and desulfurization device, including a movable opening and closing assembly 154. The movable opening and closing assembly 154 includes a straight plate 1541. A vertical plate 1542 is fixedly installed on one side of the top end of the straight plate 1541. Sealing ends 1543 are uniformly fixedly installed at the bottom end of the straight plate 1541. A second spring 1544 is fixedly installed on one side of the vertical plate 1542;

[0051] In this embodiment, it should be noted that card slots are provided on both sides of the straight plate 1541, and the card slots are slidably connected to the horizontal positioning plate 152. The closed end 1543 is arranged to fit the inner bottom end of the air outlet pipe 151 and the coverage range is larger than that of the air outlet slot 153. One end of the second spring 1544 is fixedly installed at the inner end of the air outlet pipe 151. In this way, when the machine stops, the elastic force of the second spring 1544 can be used to block the air outlet slot 153 with the closed end 1543, avoiding the liquid in the outer cylinder 1 from flowing back and ensuring the use effect of the air outlet assembly 15.

[0052] Working principle: The gas enters from the intake pipe 12 and then enters the inside of the air outlet pipe 151. The increased air pressure will compress the second spring 1544, thereby driving the closed end 1543 to open the air outlet slot 153. The gas is sprayed from the air outlet slot 153 into the liquid at the inner bottom end of the outer cylinder 1. The gas passes through the liquid and flows upward. The circulation pump 16 is started to pump the liquid in the outer cylinder 1 into the circulation pipe 17, then into the middle ring cylinder 71 and the branch pipes 72, and finally sprayed out from the spray head 73. The sprayed water mist will sediment the impurity particles in the gas and flow downward to the inner bottom end of the outer cylinder 1. At the same time, the outer drive motor 5 at the top will also be started to drive the drive rod 6 to rotate, and the drive rod 6 will drive the entire spray assembly 7 and the stirring wheel 11 to rotate. The rotation of the stirring wheel 11 will cause the liquid to rotate as a whole to generate centrifugal force, so that the dust and impurities in it will continuously accumulate on the surface of the filter ring net 43 under the action of the centrifugal force. When it is necessary to clean the surface of the filter ring net 43, just start the electric telescopic rod 18. The electric telescopic rod 18 drives the filter ring net 43 to move upward. The abutting block 45 will push the scraping groove 141 to compress the first spring 145 under the action of the limit rotating block 147. When the abutting block 45 completely passes through the limit rotating block 147, the scraping groove 141 rebounds and fits to the surface of the filter ring net 43. Then, the electric telescopic rod 18 is contracted to drive the filter ring net 43 to move downward, so that the scraping groove 141 scrapes the dust and impurities on the surface of the filter ring net 43 and collects them into the collection groove 142, ensuring the permeability of the filter ring net 43 and realizing the continuous usability of the equipment.

[0053] 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 principle and spirit of the present invention.
