Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas absorption device for waste gas treatment. Background Technique

[0002] As is well known, waste gas treatment refers to purifying the waste gas generated in the industrial production process to meet the requirements of national and local environmental protection standards. Waste gas treatment is a legal requirement that industrial enterprises must comply with and also reflects the social responsibility of enterprises. Waste gas treatment technologies include various methods such as physical, chemical, and biological methods, such as adsorption, membrane separation, catalytic oxidation, and biodegradation. Enterprises should actively adopt effective waste gas treatment measures to reduce environmental pollution and protect the ecological environment.

[0003] The Chinese Utility Model Publication Specification CN218924083U discloses a waste gas absorption device for waste gas treatment in a spray tower, including a spray tower, a fixed rod is arranged on the spray tower, and an intake pipe is arranged on the fixed rod; both ends of the intake pipe are respectively connected with a gas collecting hood and the spray tower; a dust removal component is arranged inside the intake pipe; the dust removal component includes a mounting plate arranged on the intake pipe, a motor and a rotating shaft are respectively arranged on both sides of the mounting plate; the rotating shaft is connected with the output end of the motor, and the rotating shaft passes through the mounting plate; a dust removal auger is arranged on the rotating shaft.

[0004] Although this device ensures the cleanliness inside the intake pipe, after the dust removal auger of this device is used for a long time, larger particle dust will adhere to the blade surface of the dust removal auger. When the adhered amount is relatively large, it will reduce the filtering effect. And the dust removal auger of this device is not convenient to be disassembled from the intake pipe, nor is it convenient to install and then clean. Therefore, the practicality is not very good and there is room for improvement. Content of the Utility Model

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figure 1-7, An exhaust gas absorption device for waste gas treatment of the present utility model includes a spray tower 1. A connecting pipe 2 is arranged at the left part of the spray tower 1. Several fixing plates 16 are arranged at the upper part of the connecting pipe 2. The right parts of the several fixing plates 16 are all connected to the spray tower 1. The fixing plates 16 fix the connecting pipe 2 on the spray tower 1. The lower part of the left part of the connecting pipe 2 is penetrated and connected with an air inlet pipe 3. External waste gas enters the connecting pipe 2 through the air inlet pipe 3 and then enters the exhaust gas absorption device for waste gas treatment for treatment. An installation plate 4 is arranged at the upper part of the left part of the connecting pipe 2. A connecting rod 5 is rotatably connected to the middle of the installation plate 4 through a rotating shaft and is inserted with a filtering device for filtering out larger particles in the waste gas. Several connecting plates 6 are arranged inside the left part of the connecting pipe 2. Sliding grooves 7 are arranged in the middle of the several connecting plates 6 and are slidably arranged with the filtering device. The filtering device includes a bracket 8. The two sides of the bracket 8 are respectively slid into the sliding grooves 7 of the connecting plates 6 for installation. Several first threaded holes are arranged at the lower part of the bracket 8 and are all threadedly connected with first bolts 9. Several second threaded holes are arranged at the lower parts of the several connecting plates 6 and are all threadedly connected with the corresponding first bolts 9. Screw the first bolts 9 into the second threaded holes of the connecting plates 6 and then into the first threaded holes of the bracket 8, so as to fix the bracket 8 on the connecting plates 6. A rotating rod 10 is rotatably connected to the middle of the bracket 8 through a bearing. A driving motor 15 is installed at the lower part of the rotating rod 10. Start the driving motor 15. The driving motor 15 rotates, driving the rotating rod 10 to rotate. A slot 11 is arranged at the upper part of the rotating rod 10 and is inserted with the connecting rod 5. When the bracket 8 is installed on the connecting plates 6, the slot 11 at the upper part of the rotating rod 10 is inserted with the connecting rod 5 at the lower part of the installation plate 4. Filtering auger blades 12 are arranged on the rotating rod 10. When the rotating rod 10 rotates, it drives the filtering auger blades 12 to rotate, contacts the waste gas moving in the connecting pipe 2, and filters out larger particles in the waste gas. Smaller particles enter the right part of the connecting pipe 2 through the round hole of the installation plate 4 and enter the spray tower 1 for treatment. A sealing cover 13 is penetrated and slidably connected to the lower part of the rotating rod 10. Several third threaded holes are arranged on the sealing cover 13 and are all threadedly connected with third bolts 14. Several fourth threaded holes are arranged at the lower part of the left part of the connecting pipe 2 and are all threadedly connected with the corresponding third bolts 14. Screw the third bolts 14 into the third threaded holes of the sealing cover 13 and the fourth threaded holes at the lower part of the connecting pipe 2, so as to fix the sealing cover 13 at the lower part of the connecting pipe 2 and seal the lower pipe orifice of the connecting pipe 2. Several fifth threaded holes are arranged at the lower part of the driving motor 15 and are all threadedly connected with fifth bolts 17. The lower parts of the several fifth bolts 17 are threadedly connected with a fixing frame. The upper part of the fixing frame is connected to the lower part of the sealing cover 13. The fixing frame fixes the driving motor 15 on the sealing cover 13.

[0027] To sum up, when the exhaust gas absorption device for exhaust gas treatment is in use, the staff starts the driving motor 15, and the driving motor 15 rotates, driving the rotating rod 10 and the filtering auger blades 12 to rotate, and the larger particles in the exhaust gas entering from the intake pipe 3 into the connecting pipe 2 are filtered out. When it has been used for a period of time, the filtering auger blades 12 filter a lot of particles on the surface of the filtering auger blades 12, which affects the filtering effect, the third bolt 14 can be unscrewed from the sealing cover 13, and the fifth bolt 17 can be unscrewed from the fixing frame at the same time, and the sealing cover 13 and the fixing frame can be slid down a distance. After that, the staff passes the arm and palm through the gap between the sealing cover 13 and the connecting pipe 2, extends into the interior of the connecting pipe 2, unscrews several first bolts 9, and then slides the bracket 8 out of the slide groove 7 of the connecting plate 6, and takes out the rotating rod 10 and the filtering auger blades 12 from the connecting pipe 2 for cleaning.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
