Description

Technical Field

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

[0002] In the current context of environmental governance, the importance of waste gas treatment devices is self-evident. However, existing waste gas treatment devices often face technical limitations, and their treatment methods are too single, which limits their treatment efficiency to a certain extent. Specifically, many waste gas treatment devices mainly rely on spraying to remove harmful substances in waste gas. Although spraying technology can reduce the concentration of harmful substances in waste gas to a certain extent, it is obviously impossible to achieve the ideal treatment effect by relying solely on this method.

[0003] Although the spraying method is simple and direct, it is incapable of dealing with complex exhaust gas components. There are many types of harmful substances in exhaust gas, some of which exist in the form of gas, and some may exist in the form of particles or aerosols. It is difficult to effectively remove all harmful substances by spraying alone. In addition, the solution used in the spraying process also needs to be replaced and treated regularly, which not only increases the operating cost, but also may bring new environmental problems.

[0004] The present invention provides an exhaust gas purification device with various treatment methods. Summary of the invention

[0005] In order to overcome the shortcomings of existing waste gas treatment devices that the treatment method is too single and cannot effectively reduce the concentration of harmful substances in the waste gas, resulting in substandard waste gas emissions and affecting environmental quality, the technical problem is: to provide a waste gas purification device that adopts multiple treatment methods.

[0006] The technical solution is: an exhaust gas purification device, including a reaction tower, a sprayer and an efficiency-enhancing blade. The reaction tower is divided into a waste liquid chamber, an air chamber and a deepening treatment room from bottom to top. The air inlet pipe is connected to the air chamber, and the air outlet pipe is connected to the deepening treatment room. A sprayer is arranged in the air chamber of the reaction tower. The sprayer is composed of a liquid tank, a water pipe, a water pump and an annular nozzle. The liquid tank is connected to the outside of the reaction tower. A water pump is arranged in the liquid tank. The water pump is connected to a water pipe. The end of the water pipe penetrates into the air chamber of the reaction tower and is connected to the annular nozzle. The efficiency-enhancing blade is rotatably connected in the reaction tower and is located below the sprayer. The efficiency-enhancing blade is powered by a power component. The power component is a servo motor and a rotating shaft. The servo motor is fixed above the reaction tower. The output shaft of the servo motor is connected to the rotating shaft through a coupling. The efficiency-enhancing blades are equidistantly fixed on the rotating shaft. It also includes an electrostatic adsorption mechanism. The electrostatic adsorption mechanism consists of a friction roller, a transmission gear group, a friction receptor and a conductive rod. The friction roller is rotatably connected in the deepening treatment room of the reaction tower. A conductive rod is fixed to the bottom end of the friction roller. The friction receptor is located on the inner wall of the reaction tower. The power component drives the friction roller to rotate through the transmission gear group. The friction roller and the friction receptor rub to generate static electricity, and the static electricity adsorbs dust at the conductive rod.

[0007] Furthermore, a guide groove in the direction of free fall is provided on the inner wall of the gas chamber of the reaction tower.

[0008] Furthermore, a tortuous exhaust gas outlet channel is provided at the gas outlet end of the deep processing room at the top of the reaction tower.

[0009] Furthermore, the transmission gear set is a planetary gear set, which consists of a driving gear, a driven gear and a ring gear. The driving gear is connected to the output shaft of the servo motor in the power assembly through a key, the driven gear is connected to the friction roller, the ring gear is fixed to the top surface of the reaction tower, and the friction receptor is annular and fixed under the ring gear. When the servo motor is turned on to drive the driving gear to rotate, the driving gear drives the driven gear to rotate synchronously. At the same time, the driven gear revolves in cooperation with the driving gear and the ring gear.

[0010] Furthermore, the friction roller and the friction receptor surface are both provided with rubber protrusions.

[0011] Furthermore, it also includes a cleaning mechanism, which includes a cleaning pipe, a pump and an atomizing nozzle. The lower end of the cleaning pipe is connected to the waste liquid chamber at the bottom of the reaction tower, the lower end of the cleaning pipe is connected to the pump, a pipe valve is arranged in the middle of the cleaning pipe, the upper end of the cleaning pipe is connected to the deep processing room at the top of the reaction tower, the upper end of the cleaning pipe is connected to the atomizing nozzle, and the atomizing nozzle points to the conductive rod.

[0012] Furthermore, a reflux pipe is included, which is arranged in the reaction tower and connects the inside and outside of the exhaust gas outlet channel.

[0013] Furthermore, the return pipe is provided with a water trap.

[0014] The beneficial effects are: 1. The exhaust gas is subjected to the first round of treatment through the sprayer, and then the friction roller and the friction receptor are continuously in friction contact, and the exhaust gas is further treated through the conductive rod through the principle of electrostatic adsorption, so as to effectively remove harmful substances in the exhaust gas. Compared with the existing purification device, this device uses both spraying and electrostatic adsorption to treat the exhaust gas, which improves the exhaust gas treatment effect and reduces the harmfulness of exhaust gas emissions.

[0015] 2. A tortuous exhaust gas outlet channel is provided at the top of the reaction tower, which increases the contact time and contact area between the exhaust gas and the conductive rod, improves the adsorption capacity of the conductive rod, and thus improves the exhaust gas treatment capacity.

[0016] 3. A cleaning mechanism is provided, which can pump the waste liquid in the waste liquid chamber to the atomizing nozzle for spraying and cleaning the conductive rod, thereby reducing the subsequent maintenance investment and improving the service life and practicality of the device.

[0027] Embodiment: A waste gas purification device, such as Figure 1-Figure 6 As shown, it includes a reaction tower 1, a sprayer 4 and a synergistic blade 6. The reaction tower 1 is divided into a waste liquid chamber 102, an air chamber 101 and a deepening treatment room 103 from bottom to top. The air inlet pipe 2 is connected to the air chamber 101, and the air outlet pipe 3 is connected to the deepening treatment room 103. The air chamber 101 of the reaction tower 1 is provided with a sprayer 4, and the sprayer 4 is composed of a liquid tank, a water pipe, a water pump and an annular nozzle. The liquid tank is connected to the outside of the reaction tower 1, and a water pump is provided in the liquid tank. The water pump is connected to a water pipe. The end of the water pipe penetrates into the air chamber 101 of the reaction tower 1 and is connected to an annular nozzle. The liquid tank contains a treatment liquid corresponding to the treatment of the waste gas. The synergistic blade 6 is rotatably connected in the reaction tower 1 and is located below the sprayer 4. The synergistic blade 6 is powered by a power assembly 5. The power assembly 5 is a servo motor and a rotating shaft. The servo motor is fixed above the reaction tower 1. The output shaft of the servo motor is connected to the rotating shaft through a coupling. The synergistic blade 6 is equidistantly fixed on the rotating shaft The reactor 1 also includes an electrostatic adsorption mechanism, which is composed of a friction roller 7, a transmission gear set 8, a friction receptor 9 and a conductive rod 10. There are six friction rollers 7, and the six friction rollers 7 are evenly spaced and rotatably connected to a rotating ring, and the rotating ring is rotatably connected in the deepening treatment room 103 of the reaction tower 1. The bottom end of the friction roller 7 is fixedly connected to the conductive rod 10. The deepening treatment room 103 at the top of the reaction tower 1 is provided with a tortuous exhaust gas outlet channel. The conductive rod 10 is located in the exhaust gas outlet channel. The tortuous exhaust gas outlet channel can greatly increase the contact time and contact area between the exhaust gas and the conductive rod 10, thereby improving the electrostatic adsorption treatment capacity, so as to achieve the deepening treatment effect. The friction receptor 9 is located on the inner wall of the reaction tower 1, and the power component 5 drives the friction roller 7 to rotate through the transmission gear set 8. The friction roller 7 and the friction receptor 9 rub to generate static electricity, and the static electricity is used to adsorb dust at the conductive rod 10.

[0028] like Figure 4 , Figure 5 and Figure 6As shown, the transmission gear set 8 is a planetary gear set, and the transmission gear set 8 is composed of a driving gear, a driven gear and a ring gear. The driving gear is connected to the output shaft of the servo motor in the power assembly 5 through a key, and the driven gear is connected to the friction roller 7. The ring gear is fixed to the top surface of the reaction tower 1, and the friction receptor 9 is annular and fixed below the ring gear. The servo motor is turned on to drive the driving gear to rotate, and the driving gear drives the driven gear to rotate synchronously. At the same time, the driven gear revolves in cooperation with the driving gear and the ring gear, that is, the friction roller 7 revolves while rotating, so that the friction roller 7 can be in friction contact with the friction receptor 9. The friction roller 7 and the friction receptor 9 are made of fluoroprene rubber material, and the surfaces of the friction roller 7 and the friction receptor 9 are provided with rubber protrusions to improve the friction electrification efficiency. The static electricity generated by the two will be introduced into the conductive rod 10, and the conductive rod 10 adsorbs the fine dust in the exhaust gas.

[0029] like Figure 4 As shown, the inner wall of the air chamber 101 of the reaction tower 1 is provided with a guide groove 1001 in the direction of free fall. When the sprayer 4 sprays the exhaust gas to reduce dust, the waste liquid will flow downward under the action of the guide groove 1001, thereby reducing the amount of dust attached to the inner wall of the air chamber 101, reducing subsequent maintenance costs, and achieving a self-cleaning effect.

[0030] like Figure 7 and Figure 8 As shown, a cleaning mechanism is also included, which includes a cleaning pipe 11, a pump 12 and an atomizing nozzle 13. The lower end of the cleaning pipe 11 is connected to the waste liquid chamber 102 at the bottom of the reaction tower 1, the lower end of the cleaning pipe 11 is connected to the pump 12, a pipe valve 1101 is arranged in the middle of the cleaning pipe 11, the upper end of the cleaning pipe 11 is connected to the deep processing room 103 at the top of the reaction tower 1, the upper end of the cleaning pipe 11 is connected to the atomizing nozzle 13, and the atomizing nozzle 13 points to the conductive rod 10.

[0031] like Figure 7 and Figure 8 As shown, a reflux pipe 14 is also included. The reflux pipe 14 is arranged in the reaction tower 1 and connects the inside and outside of the exhaust gas outlet channel. The reflux pipe 14 is provided with a water trap. Part of the waste liquid is retained in the water trap. The provision of the water trap does not affect the discharge of the waste liquid from the exhaust gas outlet channel, and the reflux pipe 14 can be closed to prevent the exhaust gas from escaping.

[0032] The working principle of the embodiment of the present invention is as follows: the power assembly 5 drives the efficiency-enhancing blade 6 to rotate, and then the sprayer 4 is turned on to continuously spray the treatment liquid. The air inlet pipe 2 of the device is connected to the exhaust gas end, and the exhaust gas enters the air chamber 101 of the reaction tower 1, and then fully fuses and reacts with the treatment liquid. The treatment liquid solidifies the harmful substances in the exhaust gas. The efficiency-enhancing blade 6 can not only disturb the exhaust gas and increase the contact area between the treatment liquid and the exhaust gas, but also can receive the waste liquid that absorbs the harmful substances and solidify them through centrifugal action. The waste liquid is guided to the inner wall of the air chamber 101, and the waste liquid is introduced into the waste liquid chamber 102 through the guide groove 1001. At this point, the waste gas will complete the spray treatment. At this time, part of the waste gas still carries harmful substances and escapes upward. The waste gas will enter the deep processing room 103, which is provided with a tortuous waste gas outlet channel. During this period, the power component 5 continues to drive the friction roller 7 to perform circular motion and self-rotation through the transmission gear group 8. The friction roller 7 will continue to be frictionally charged with the friction receptor 9, and the static electricity will be transmitted to the conductive rod 10, and by The conductive rod 10 located in the exhaust gas outlet channel continuously electrostatically adsorbs the exhaust gas to achieve the effect of deepening treatment. It is worth explaining in detail that the deepening treatment room 103 is divided into an upper space and a lower space. The lower space is the exhaust gas outlet channel, and a transmission gear set 8, a friction roller 7 and a friction receptor 9 are arranged in the upper space. A rotating partition is arranged at the connection between the upper space and the lower space. The conductive rod 10 is rotatably connected to the partition. The upper space and the lower space are not intercommunication, thereby ensuring the stable and safe outlet of the exhaust gas. The exhaust gas is discharged from the exhaust pipe 3. After a large amount of harmful dust is attached to the conductive rod 10, it can be cleaned by a cleaning mechanism, that is, the pump 12 is turned on to pump the waste liquid in the waste liquid chamber 102 to the atomizing nozzle 13 for spraying. Since the conductive rod 10 continues to rotate, the atomizing nozzle 13 can fully and efficiently rinse the conductive rod 10, and then the waste liquid falls into the exhaust gas outlet channel, and then the reflux pipe 14 guides the waste liquid in the exhaust gas outlet channel back to the waste liquid chamber 102, so that the treatment liquid is fully utilized and material waste is reduced.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
