[0001] The invention relates to the technical field of copper smelting waste gas treatment, and in particular to a waste gas treatment device for copper smelting. Background Art

[0002] With the acceleration of industrialization, the copper smelting industry has flourished. However, the copper smelting process will produce a large amount of harmful gases. If discharged directly, the waste gas may not only cause acid rain, soil acidification, water pollution, and harm the ecology; it may also deteriorate air quality, cause haze, and threaten the health of the human respiratory system.

[0003] Therefore, it is necessary to use exhaust gas treatment equipment, with the help of advanced exhaust gas treatment technology, to effectively purify harmful gases before they are discharged.

DETAILED DESCRIPTION

[0031] 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.

[0032] Example 1: Please refer to Figure 1 to Figure 5 , a waste gas treatment device for copper smelting, comprising a treatment pipe 1, one end of the treatment pipe 1 is fixedly connected to an air intake pipe 3, and the end of the treatment pipe 1 away from the air intake pipe 3 is fixedly connected to a control valve 4 for detecting the waste gas treatment effect;

[0033] The inner cavity of the treatment tube 1 is fixedly installed with a filter structure for filtering smoke and dust in the exhaust gas. The filter membrane 701 of the filter structure is installed in the inner cavity of the treatment tube 1 to filter and separate the smoke and dust in the exhaust gas.

[0034] The inner cavity of the treatment tube 1 is fixedly installed with a purification structure for chemically purifying the waste gas. The fixing frame 801 of the purification structure is fixedly connected to the inner wall of the treatment tube 1. The inner cavity of the fixing frame 801 is slidably installed with a feed plate 802 for providing a reducing agent for purifying the waste gas. The inner cavity of the fixing frame 801 is rotatably installed with a plurality of three-sided flaps 803 for contacting and purifying the waste gas, and the three-sided flaps 803 are fitted with the feed plate 802. The three-sided flaps 803 rotate and fit with the feed plate 802 to absorb sufficient reducing agent to chemically purify the waste gas.

[0035] Specifically, the bottom end of the treatment tube 1 is fixedly connected to a support frame 2 for supporting and fixing the treatment tube 1, the top end of the control valve 4 is fixedly connected to a reflux pipe 5 for conveying waste gas reflux, and the bottom end of the control valve 4 is fixedly installed with an outlet pipe 6 for discharging waste gas;

[0036] The filtering structure includes a fixing plate 702, two fixing plates 702 are provided and both are fixedly connected to the inner wall of the processing tube 1, a filtering tube 703 for providing airflow is fixedly connected between the two fixing plates 702, and a filtering membrane 701 is installed in the filtering tube 703, and a cleaning structure for removing dust on the filtering membrane 701 is fixedly connected to the inner cavity of the filtering tube 703;

[0037] Specifically, there are a plurality of filter tubes 703 symmetrically and evenly distributed between the two fixed plates 702 , a plurality of filter membranes 701 are installed in the inner cavity of each filter tube 703 , and the cleaning structure is located between every two filter membranes 701 ;

[0038] More specifically, the filter membrane 701 is made of polypropylene, and filter holes are provided inside the filter membrane 701. After the filter membrane 701 has been used for a long time, the filtered dust may clog the filter holes, causing the exhaust gas to encounter resistance when passing through the filter membrane 701, thereby pushing the filter membrane 701 to bulge and enlarging the filter holes. The dust in the filter holes is removed by airflow, and the bulging filter membrane 701 is close to the removal structure. The flow of airflow drives the removal structure to vibrate, and the vibration energy can be effectively transmitted to the air near the filter membrane 701, generating strong airflow disturbance, thereby making it easier to shake off the dust particles on the surface of the filter membrane 701.

[0039] More specifically, both sides of each filter membrane 701 are fixedly connected with a circular outer frame 704 for fixing and limiting the filter membrane 701, and the outer wall of the circular outer frame 704 is fixedly connected to the inner wall of the filter tube 703;

[0040] The cleaning structure includes a fixed shaft 705, which is fixedly installed in the inner cavity of the filter tube 703, and a vibration sheet 706 for assisting in cleaning the filter membrane 701 is rotatably sleeved on the outer wall of the fixed shaft 705, and the vibration sheet 706 is located on one side of the filter membrane 701;

[0041] Specifically, the installation direction of the flutter plate 706 is perpendicular to the airflow direction, and the fixed shaft 705 provides a rotation support point for the flutter plate 706. The vertical installation can more efficiently utilize the airflow energy.

[0042] More specifically, in order to limit the vibration range of the vibration sheet 706, the upper and lower ends of each vibration sheet 706 are fixedly connected to the limit shaft 707, and the outer wall of the fixed shaft 705 is fixedly sleeved with a limit frame 708. The left and right ends of the limit frame 708 are provided with sliding grooves for providing sliding of the limit shaft 707, and the limit shaft 707 is located in the sliding groove, which effectively prevents the vibration sheet 706 from deviating or swinging significantly due to irregular fluctuations of the airflow or instantaneous strong airflow impact, and avoids hard collision with the inner wall of the filter tube 703 or the adjacent filter membrane 701. At the same time, the vibration amplitude of the vibration sheet 706 is limited to ensure that the airflow disturbance created by it near the filter membrane 701 is more uniform and stable, and can accurately and continuously act on the surface of the filter membrane 701, so as to shake the dust particles off the filter membrane 701 rhythmically, ensure the filtering accuracy of the filter membrane 701, and ensure that the impurities in the exhaust gas are efficiently intercepted;

[0043] The bottom end of each filter tube 703 is fixedly connected with a collection tank box 709 for collecting dust, and the bottom end of the processing tube 1 is fixedly installed with a collection box 710 for uniformly collecting dust, and the collection box 710 and the collection tank box 709 are fixedly connected through a pipeline;

[0044] Specifically, an air pump 711 for providing collection suction is fixedly connected to one side of the collection box 710, and the suction end of the air pump 711 is connected to the interior of the collection box 710 through a pipe. A filter plate 712 for filtering and separating impurities is fixedly connected to the inner cavity of the collection box 710, and a collection pull box 713 for accumulating dust is slidably installed in the inner cavity of the collection box 710.

[0045] Example 2: Please refer to Figure 1-2 , Figure 6 to Figure 8 , a waste gas treatment device for copper smelting, which differs from Example 1 in that the purification structure further includes a positioning plate 804, the positioning plate 804 is fixedly installed in the inner cavity of the fixing frame 801, a total of two positioning plates 804 are provided, and a rotating shaft 805 is rotatably connected between the two positioning plates 804 through a bearing, a three-sided flap 803 is fixedly sleeved on the outer wall of the rotating shaft 805, and a driving structure for driving the three-sided flap 803 to flip is fixedly connected to the bottom end of the rotating shaft 805;

[0046] Specifically, a storage box 806 and a water pump 807 for conveying the reducing agent are fixedly installed on the top surface of the fixing frame 801, and the storage box 806 and the water pump 807 are fixedly connected by a pipeline, and the water outlet of the water pump 807 is connected to the feed plate 802 through a pipeline, and a hydrophilic sponge is fixedly provided on one side of the feed plate 802 close to the three-sided flap 803 and on the outer wall of the three-sided flap 803, so that the reducing agent can be evenly distributed on the surface of the feed plate 802, ensuring that the three-sided flap 803 can fully absorb the required reducing agent when the feed plate 802 is attached;

[0047] More specifically, a spring 812 for providing movement of the feed plate 802 is fixedly installed on one side of the feed plate 802 away from the three-sided flap 803, one end of the spring 812 is fixedly connected to a bottom plate 813, and the bottom plate 813 is fixedly connected to the fixing frame 801. Since the three-sided flap 803 is set in a triangle shape, in order to ensure that the three-sided flap 803 can fully fit the feed plate 802, when the three-sided flap 803 is turned over, it will push the feed plate 802 to squeeze the spring 812, thereby providing space for the three-sided flap 803 to turn over;

[0048] The driving structure includes a triangular gear 808, which is fixedly mounted on the bottom end of the rotating shaft 805. The bottom end of the inner cavity of the fixed frame 801 is rotatably connected to a rotating shaft 809 through a bearing. A driving wheel 810 for driving the triangular gear 808 to rotate is fixedly sleeved on the outer wall of the rotating shaft 809, and the driving wheel 810 is meshed with the triangular gear 808.

[0049] Specifically, a drive motor 811 is installed below the rotating shaft 809, and the drive motor 811 is fixedly connected to the bottom end of the inner cavity of the fixed frame 801. The output end of the drive motor 811 and one end of the rotating shaft 809 are both fixedly connected with pulleys, and the two are rotationally connected by a belt.

[0050] Example 3: Please refer to Figure 2 , Fig. 9 , a waste gas treatment device for copper smelting, which differs from Example 1 in that a fan 9 is fixedly connected to the inner wall of a treatment tube 1, and a rotating fan blade 10 is fixedly connected to the output end of the fan 9, and the fan 9 drives the rotating fan blade 10 to rotate to suck the waste gas into the treatment tube 1.

[0051] See also Figure 1-2 , Fig.10 The inner cavity of the control valve 4 is rotatably connected to a bent rotating rod 401 through a bearing, and a rotating block 402 is fixedly sleeved on the outer wall of the bent rotating rod 401. One end of the rotating block 402 is rotatably connected to a push rod 403 through a pin shaft, and the other end of the rotating block 402 is rotatably connected to a moving rod 404 through a pin shaft, one end of the push rod 403 is fixedly connected to a throttle plug 405, and one end of the moving rod 404 is fixedly connected to a throttle plate 406;

[0052] Specifically, a monitor for real-time monitoring of the exhaust gas treatment effect and a sensor for controlling the operation of the drive motor 811 are fixedly installed on the outer wall of the control valve 4, and a motor 407 for controlling the rotation of the bending rotating rod 401 is fixedly installed inside the control valve 4, and the output end of the motor 407 is fixedly connected to the bending rotating rod 401.

[0053] The working principle of the present invention is:

[0054] First, the waste gas generated by copper smelting enters the treatment tube 1 through the air inlet pipe 3, and is sucked by the rotating blades 10 driven by the fan 9, and the waste gas is transported to the treatment tube 1 for treatment;

[0055] The exhaust gas first enters the filtering structure, and the filter tube 703 is equipped with a multi-layer polypropylene filter membrane 701. The airflow passes through the filter holes on the filter membrane 701, and the smoke and dust particles in the exhaust gas are intercepted. If the smoke and dust block the filter holes, the airflow pushes the filter membrane 701 to bulge and involves expanding the filter holes. The airflow is used to blow and remove the dust in the filter holes. At the same time, the vibration sheet 706 vibrates through the airflow, and the vibration energy can be effectively transmitted to the air near the filter membrane 701, generating a strong airflow disturbance, so that it is easier to shake off the dust particles on the surface of the filter membrane 701. The dust on the surface of the filter membrane 701 is effectively cleaned, and the removed dust is collected into the collection box 710 through the collection tank box 709 at the bottom of the filter tube 703. The air pump 711 provides suction to collect the dust in the collection pull box 713, and clean it regularly;

[0056] Then the filtered exhaust gas enters the purification structure, and the exhaust gas passes through the three-sided flap 803, so that the exhaust gas reacts chemically with the reducing agent on the surface of the three-sided flap 803 to convert and purify the pollutants in the exhaust gas. The purified exhaust gas enters the control valve 4 and is discharged from the outlet pipe 6;

[0057] When the monitor detects that the exhaust gas treatment effect does not meet the standard, the signal is transmitted to the motor 407 in the control valve 4 through the sensor, and the motor 407 drives the bending rotating rod 401 to rotate, and the push rod 403 drives the throttle plug 405 to close the outlet pipe 6, and at the same time the moving rod 404 drives the throttle plate 406 to open the return pipe 5, and the exhaust gas that does not meet the standard is transported back to the treatment pipe 1 by the return pipe 5, and is filtered and chemically purified again;

[0058] At the same time, the signal is also transmitted to the water pump 807 through the sensor, and the liquid reducing agent in the storage box 806 is evenly distributed to the surface of the supply plate 802 through the water pump 807. The driving motor 811 rotates through the belt drive shaft 809, and the driving wheel 810 mounted on the shaft 809 engages with the triangular gear 808 to drive the three-sided flap 803 to rotate, so that the three-sided flap 803 is in contact with the supply plate 802 to replenish the reducing agent, thereby ensuring that the reducing agent is in full contact with the exhaust gas, a chemical reaction occurs, and the pollutants in the exhaust gas are converted and purified.

[0059] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed in the present invention, which should be covered by the protection scope of the present invention.
