DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figures 1 to 7 As shown, the present invention provides an energy-saving and environmentally friendly water circulation waste gas treatment device, including a lifting device 1 and a carrying plate 2, and the lifting device 1 is arranged on one side of the carrying plate 2, a carrying shaft 3 is arranged at the bottom of the lifting device 1, and a plurality of rotating devices 4 are evenly arranged on the circumference of the carrying shaft 3, and an air outlet device 5 is arranged at the bottom of each rotating device 4, and the plurality of air outlet devices 5 are connected to an air inlet pipe, and each air inlet pipe is provided with a solenoid valve, and a plurality of treatment boxes 6 for containing liquid medicine and with open tops corresponding to the plurality of air outlet devices 5 are evenly arranged on the carrying plate 2, and each air outlet device 5 is lowered into the treatment box 6 when treating the waste gas, and the air outlet device 5 closes the top of the treatment box 6 when treating the waste gas, and a separation structure 7 for separating sediment and wastewater is arranged in each treatment box 6, and a recovery device 8 for recovering sediment and wastewater respectively is arranged on the outer wall of each treatment box 6.

[0031] When the technical solution of the present application is actually applied, multiple treatment boxes 6 are filled with liquid medicine for treating exhaust gas. Then the lifting device 1 drives the load-bearing shaft 3 to drive multiple rotating devices 4 and multiple air outlet devices 5 to descend synchronously until the air outlet device 5 is located below the liquid medicine in the treatment box 6. At the same time, the air outlet device 5 seals the top of the treatment box 6. Then the exhaust gas enters the air outlet device 5 through the air inlet pipe. The exhaust gas in the air outlet device 5 is passed into the liquid medicine, so that the exhaust gas can fully contact with the liquid medicine for reaction, so as to ensure that the exhaust gas can be fully treated before being discharged, thereby avoiding harm to the environment and human body.

[0032] In this embodiment, the treated waste gas is discharged outside the top area of ​​the closed treatment box 6 through the gas outlet device 5, and is collected by a designated device or transferred to a designated area for discharge.

[0033] While the exhaust gas is introduced into the exhaust device 5, the rotating device 4 drives the corresponding exhaust device 5 to rotate, so that the exhaust device 5 stirs the medicinal liquid in the treatment box 6, and the position of the exhaust gas introduced into the exhaust device 5 is evenly distributed in the rotating area of ​​the exhaust device 5, so that the introduced exhaust gas will not gather together and contact with the surrounding medicinal liquid, but will be dispersed and contact with the medicinal liquid, thereby further improving the treatment effect of the exhaust gas and the utilization rate of the medicinal liquid.

[0034] After the waste gas is treated with the liquid medicine, precipitates will appear. When the waste water (liquid medicine that has been used to treat the waste gas and has become ineffective) and the precipitates are recovered by the recovery device 8 through the separation structure 7, the precipitates and the waste water can be recovered separately, thereby improving the recovery efficiency and realizing the recycling of waste water, which has energy-saving and environmental protection effects.

[0035] Moreover, multiple treatment boxes 6 can treat the waste gas at the same time or alternately. At this time, the ineffective liquid medicine is collected by the recovery device 8, so that the waste gas can continue to be treated by the liquid medicine in other treatment boxes 6, thereby improving the treatment efficiency.

[0036] Furthermore, a liquid inlet pipe for introducing liquid medicine may be installed on the processing box 6 to improve the convenience of using the device.

[0037] In this embodiment, the lifting device 1 and the rotating device 4 are both existing technologies. For example, the lifting device 1 is a hydraulic push rod, and the rotating device 4 is directly driven by a motor, etc. The technical principles will not be elaborated in detail.

[0038] The air outlet device 5 includes a connecting seat 501 connected to the rotating device 4, a hollow rotating shaft 502 is arranged at the bottom of the connecting seat 501, a connecting sleeve 503 connected to the air inlet pipe is sealed and rotatably sleeved on the hollow rotating shaft 502, a plurality of air inlets 504 located inside the connecting sleeve 503 are evenly opened around its own axis on the hollow rotating shaft 502, an air outlet pipe 505 is connected to the bottom of the hollow rotating shaft 502, and both ends of the air outlet pipe 505 are closed, the middle part of the air outlet pipe is connected to the inside of the hollow rotating shaft 502, a plurality of shunt pipes 506 are evenly spaced along the axial direction of the air outlet pipe 505, and a one-way valve 506 is arranged at the end of each shunt pipe 506. 7. A cover plate 508 is rotatably provided on the hollow rotating shaft 502 and is located between the connecting sleeve 503 and the exhaust pipe 505, and the cover plate 508 is used to close the top of the processing box 6. The cover plate 508 and the outer wall of the hollow rotating shaft 502 are jointly provided with a connecting piece, and the connecting piece limits the rotation of the cover plate 508 around the axis of the hollow rotating shaft 502 by gravity, and releases the restriction on the cover plate 508 by pressing the cover plate 508 against the top of the processing box 6. An exhaust pipe 510 for exhausting waste gas is provided on the top of the cover plate 508, a plurality of positioning pins 514 are provided on the bottom of the cover plate 508, and a plurality of positioning holes 515 for inserting the positioning pins 514 are provided on the top of the processing box 6.

[0039] After the air outlet pipe 505 completely enters the medicine liquid in the treatment box 6, the cover plate 508 is abutted against the top of the treatment box 6, the positioning pin 514 is inserted into the corresponding positioning hole 515, and the cover plate 508 is pushed by the treatment box 6, so that the connecting part releases the restriction on the cover plate 508, so that when the hollow rotating shaft 502 rotates, the cover plate 508 is fixed to the top of the treatment box 6 through the matching connection between the positioning pin 514 and the positioning hole 515, instead of rotating with the hollow rotating shaft 502, thereby ensuring the sealing effect of the top of the treatment box 6.

[0040] The exhaust gas enters the connecting sleeve 503 through the air inlet pipe, and enters the hollow rotating shaft 502 through the air inlet port 504, then enters the multiple branch pipes 506 through the air outlet pipe 505, and is discharged into the liquid medicine in the treatment box 6 through multiple one-way valves 507 for treatment. The exhaust gas is discharged through multiple one-way valves 507, so that the exhaust gas contacts the liquid medicine as evenly as possible for sufficient treatment, thereby improving the treatment effect of the exhaust gas. The treated exhaust gas is discharged through the exhaust pipe 510.

[0041] After the rotating device 4 is started, the rotating device 4 drives the connecting seat 501 to drive the hollow rotating shaft 502 to rotate, and the air outlet pipe 505 rotates synchronously with the hollow rotating shaft 502, so that the medicine liquid in the treatment box 6 is stirred by the rotation of the air outlet pipe 505, so that the exhaust gas is evenly dispersed into the interior of the medicine liquid for treatment, ensuring that the medicine liquid treats the exhaust gas and improving the treatment effect of the exhaust gas.

[0042] When the hollow rotating shaft 502 rotates, the connecting sleeve 503 rotates on the hollow rotating shaft 502 under the restriction of the air intake pipe, thereby avoiding the interference of the air intake pipe on the rotation of the hollow rotating shaft 502 .

[0043] In this embodiment, the one-way valve 507 is a prior art and is used to limit waste water and sediment from entering the air outlet pipe 505 .

[0044] The pipe opening on the diversion pipe 506 faces the inner bottom of the processing box 6.

[0045] The introduced waste gas can impact the liquid medicine at the bottom of the treatment box 6, thereby causing the liquid medicine to surge, further improving the treatment effect of the liquid medicine on the waste gas and the utilization rate of the liquid medicine.

[0046] The connecting part includes a magnetic annular plate 511 which is arranged on the outer wall of the hollow rotating shaft 502 and is concentric therewith. The bottom of the cover plate 508 can be attracted to the magnetic annular plate 511 by magnetic force. A clamping strip 512 is vertically arranged on the top of the magnetic annular plate 511. A clamping slot 513 is opened on the cover plate 508 for the clamping strip 512 to pass through, and the exhaust pipe 510 is located above the clamping slot 513 and is connected to the clamping slot 513.

[0047] When the cover 508 is not in contact with the top of the processing box 6, the bottom of the cover 508 is in contact with the top of the magnetic annular plate 511, so that the cover 508 is supported by the magnetic annular plate 511, and the clamping strip 512 is inserted into the clamping groove 513, so that the cover 508 cannot rotate around the hollow rotating shaft 502, thereby ensuring that the positioning pin 514 at the bottom of the cover 508 can be accurately inserted into the positioning hole 515.

[0048] After the cover 508 abuts against the top of the processing box 6, the lifting device 1 is driven to lift the cover 508 by the top of the processing box 6 until the clamping strip 512 is disengaged from the clamping slot 513, thereby releasing the restriction on the rotation of the cover 508 and allowing the cover 508 to rotate around the axis of the hollow rotating shaft 502, thereby avoiding interference with the rotation of the hollow rotating shaft 502.

[0049] After the exhaust gas treatment is completed, the exhaust pipe 505 rotates to the initial position so that the clamping strip 512 is aligned with the clamping groove 513 .

[0050] The separation structure 7 includes two filter plates 701 which are obliquely symmetrically arranged on the inner wall of the processing box 6, and the tops of the two filter plates 701 are connected to each other. The upper surface of each filter plate 701 is provided with two guide blocks 702 which are in contact with the inner wall of the processing box 6, and the two guide blocks 702 on the same filter plate 701 are located on both sides of the upper surface of the filter plate 701.

[0051] When the drug solution becomes ineffective or the treatment of the waste gas is completed, the waste water is recovered from the bottom of the filter plate 701 by the drug solution recovery device 8 for recycling, and the sediment remains on the filter plate 701 and slides downward along the surface of the guide block 702 and the filter plate 701 into the drug solution recovery device 8 by gravity, thereby realizing the separate recovery of the sediment and the waste water and improving the convenience of use.

[0052] A sliding push plate 703 that slides in the horizontal direction is slidably connected to the inner wall of the processing box 6. A roller 704 located below the filter plate 701 and an elastic paddle 705 that is perpendicular to the horizontal plane are provided on the side of the sliding push plate 703 that faces the center of the processing box 6. The roller 704 and the elastic paddle 705 are respectively located at the lower end and the upper end of the sliding push plate 703. A shield plate 706 that is slidingly sealed to the top of the guide block 702 is fixedly connected to the sliding push plate 703. A guide groove 707 for the sliding push plate 703 to slide is jointly provided on the inclined outer side of the filter plate 701 and the guide block 702.

[0053] The two filter plates 701 are both slidably connected to the inner wall of the processing box 6, and the sliding direction of the filter plates 701 is perpendicular to the horizontal plane.

[0054] When the air outlet pipe 505 rotates, it will contact the elastic paddle 705, and the elastic paddle 705 drives the sliding push plate 703 to slide on the inner wall of the processing box 6, so that the roller 704 abuts against the bottom of the filter plate 701, and the filter plate 701 moves upward due to the pressure of the roller 704. When the air outlet pipe 505 pushes the elastic paddle 705 until the sliding push plate 703 contacts the inner side wall of the guide groove 707, the air outlet pipe 505 squeezes the elastic paddle 705 to cause greater elastic deformation, so that The air outlet pipe 505 passes over the elastic paddle 705 and loses contact with the elastic paddle 705. Under the gravity of the filter plate 701 and the guide block 702, the roller 704 is forced to move in the opposite direction and drives the sliding push plate 703 to reset. As the air outlet pipe 505 circulates, the filter plate 701 can move up and down. When the liquid medicine recovery device 8 recovers the precipitate and wastewater, the precipitate slides down due to the up and down movement of the filter plate 701, thereby improving the collection effect of the precipitate.

[0055] The shield plate 706 is used to limit the sediment from falling below the filter plate 701 through the guide groove 707, thereby preventing the sediment from mixing with the wastewater when being discharged out of the treatment box 6.

[0056] The two filter plates 701 are connected to counterweights 708 by ropes below, which can accelerate the downward movement of the filter plates 701 for resetting.

[0057] The drug liquid recovery device 8 includes sedimentation discharge pipes 801 respectively arranged on two opposite outer walls of the treatment box 6 and a sewer pipe 804 arranged on the outer wall of the treatment box 6, and the top of each sedimentation discharge pipe 801 extends to communicate with the interior of the treatment box 6, and each sedimentation discharge pipe 801 and the sewer pipe 804 are provided with a valve body, and are respectively opposite to the bottom of the two filter plates 701, the bottoms of the two sedimentation discharge pipes 801 are commonly connected to a collecting box 802, and the end of the sewer pipe 804 is connected to a recovery water tank 805, and a baffle 803 perpendicular to the horizontal plane is provided at the lower edge of each filter plate 701, and each baffle 803 is in contact with the inner wall of the treatment box 6 and is located below the top of the corresponding sedimentation discharge pipe 801.

[0058] After the exhaust gas is stopped, the two valve bodies are opened, so that the sediment discharge pipe 801 and the sewer pipe 804 are opened, and the sediment slides down through the filter plate 701 to the sediment discharge pipe 801 and enters the corresponding collection box 802. The wastewater enters the recovery water tank 805 through the sewer pipe 804 for collection.

[0059] The baffle 803 is provided to restrict sediment from entering the space below the filter plate 701 in the processing box 6 from the edge of the filter plate 701 when the filter plate 701 moves up and down.

[0060] In this embodiment, the recovery water tank 805 and the collection box 802 are both arranged below the supporting plate 2. For example, a plurality of first support columns are arranged below the supporting plate, a first bottom plate is commonly arranged at the bottom of the plurality of first support columns, a plurality of second support columns are arranged at the bottom of the first bottom plate, a second bottom plate is commonly arranged at the bottom of the plurality of second support columns, a plurality of recovery water tanks 805 are arranged on the second bottom plate, and a plurality of collection boxes 802 are arranged on the first bottom plate.
