Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic precipitators, in particular to a vertical wet electrostatic precipitator. Background Art

[0002] With the continuous development of society, the scale of industrial production is also increasing. In modern industrial production, smoke containing a large amount of harmful dust will be generated in some processes. These smoke need to be strictly treated before they can be discharged to avoid pollution to the environment. Vertical wet electrostatic precipitator is one of the more typical equipment in this treatment process. It absorbs harmful dust in the smoke through static electricity and other methods, and further cleans and collects the dust through spraying and other methods.

[0003] In order to avoid wasting water resources, some existing vertical wet electrostatic precipitators will use circulating water for spraying during use. Although the clean water will be filtered during this process, filtering alone is too simple and the effect needs to be improved. In particular, some fine dust is difficult to separate from the clean water by filtering, which causes serious damage to the subsequent water pumps and pipes used for circulating water, requiring frequent maintenance of the equipment. Utility Model Content

[0030] like Figure 2 and Figure 3 As shown, a collecting, filtering and guiding chamber 5 is installed at the middle position inside the vertical electrostatic precipitator main body 1, and partition plates 6 are installed on both sides of the bottom of the collecting, filtering and guiding chamber 5. A water flow through hole 7 is opened on one side of the partition plate 6. The partition plate 6 divides the bottom space of the vertical electrostatic precipitator main body 1 into three independent water storage spaces. The collecting, filtering and guiding chamber 5 guides the sprayed and filtered water to the first water storage space far away from the water pump 4, and the vertical electrostatic precipitator main body 1 corresponds to a sewage pipe connected to each water storage space, and the water storage space close to the water pump 4 is correspondingly connected to a water supply pipe;

[0031] like Figure 2 and Figure 3 As shown, a ball valve 8 is arranged inside the water flow through hole 7, a rotating rod 9 is installed at the bottom of the outer side wall of the ball valve 8, and the rotating rod 9 passes through the partition plate 6 and the vertical electrostatic precipitator cylinder body 1 respectively, and a limiting groove 10 is provided on the outer side wall of the rotating rod 9, and a gear body 11 is installed at the bottom end of the rotating rod 9, the central axis of the rotating rod 9 is perpendicular to the transverse central axis of the partition plate 6, and the rotating rod 9 is rotatably connected to the partition plate 6 and the vertical electrostatic precipitator cylinder body 1 respectively, and when the rotating rod 9 rotates, the ball valve 8 can be driven to open the corresponding water flow through hole 7 or close the corresponding water flow through hole 7, and the rotating rod 9 can be connected to the vertical electrostatic precipitator cylinder body 1 through a sealed bearing;

[0032] like Figure 2 and Figure 3As shown, a driving mechanism for driving the rotating rod 9 to rotate intermittently is provided on the vertical electrostatic precipitator body 1, and the driving mechanism is used to squeeze the limiting mechanism, and the driving mechanism includes a motor 15, the motor 15 is installed at the middle position of the bottom of the vertical electrostatic precipitator body 1, and an output shaft 16 is installed at the output end of the motor 15, an incomplete gear 17 is installed at the bottom end of the output shaft 16, and an eccentric wheel 18 is installed on the outer side of the output shaft 16, the central axis of the incomplete gear 17 is parallel to the central axis of the gear body 11, and the incomplete gear 17 is located at a position meshing with the gear body 11, when the motor 15 drives the incomplete gear 17 to rotate through the output shaft 16, the incomplete gear 17 can intermittently mesh with one group of the two groups of gear bodies 11, and drive the rotating rod 9 of this group to rotate one circle, when the incomplete gear 17 is driven by the motor 15 through the output shaft 16 When the complete gear 17 is meshed with a group of gear bodies 11 far away from the water pump 4, the water in the water storage space far away from the water pump 4 flows into the middle water storage space. When the incomplete gear 17 is meshed with a group of gear bodies 11 close to the water pump 4, the water in the middle water storage space flows into the water storage space close to the water pump 4, so that the water pump 4 can perform delivery and spraying. The tooth block distribution angle on the incomplete gear 17 is less than 180°, and the two groups of ball valves 8 are in a closed state in the initial state, so that there is a period of time when the incomplete gear 17 is completely not meshed with any of the two groups of gear bodies 11. At this time, the three groups of water storage spaces are completely in a mutually closed state, and the middle water storage space is not affected by the external water flow at this time, so that the static task can be completed, and then the task of treating clean water can be further completed. Example

[0033] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a limit mechanism for limiting the rotation of the rotating rod 9 is provided on the vertical electrostatic precipitator body 1, and the limit mechanism includes two sets of fixed plates 12, and the two sets of fixed plates 12 are respectively installed on one side of the bottom of the vertical electrostatic precipitator body 1, and one side of the fixed plate 12 passes through a limit rod 13, and a spring 14 is connected between the limit rod 13 and the fixed plate 12, and the end of the limit rod 13 away from the vertical electrostatic precipitator body 1 is spherical, and the limit rod 13 and the fixed plate 12 are slidably connected. Under normal conditions, the limit rod 13 is always It slides in the corresponding limit groove 10, thereby limiting the rotation of the rotating rod 9. Only when the incomplete gear 17 begins to mesh with the corresponding gear body 11, the squeezing amplitude of the eccentric wheel 18 on the corresponding limit rod 13 will be reduced to the extent that the limit rod 13 begins to leave the corresponding limit groove 10, thereby releasing the rotation restriction of the rotating rod 9 when the rotating rod 9 rotates. In other time periods, the rotating rod 9 is in a state of being restricted in rotation by the corresponding limit rod 13, thereby fully ensuring the stability of the ball valve 8 and further ensuring its sealing effect.

[0034] The working principle of the utility model: during use, smoke is sent into the vertical electrostatic dust collector body 1 from the smoke inlet pipe, the vertical electrostatic dust collector body 1, the water pump 4 and the motor 15 are turned on, and after the smoke enters the vertical electrostatic dust collector body 1, the vertical electrostatic dust collector body 1 adsorbs the dust in the smoke and discharges it through the pipe on the top of the vertical electrostatic dust collector body 1 to enter the next treatment process, the water pump 4 transports the treated water in the water storage space at the bottom of the vertical electrostatic dust collector body 1 close to the filter bin 3 to the water distributor 2 corresponding to the smoke and the smoke treatment part of the vertical electrostatic dust collector body 1 for spraying, and then the clean water falls into the interior of the collecting filter diversion bin 5, the collecting filter diversion bin 5 filters the clean water and diverts it to the water storage space away from the water pump 4.

[0035] In the above process, the motor 15 drives the output shaft 16 and the incomplete gear 17 to rotate continuously. When the incomplete gear 17 is meshed with the gear body 11 on the side away from the water pump 4, the squeezing amplitude of the eccentric wheel 18 on the corresponding limiting rod 13 is reduced to the extent that the group of limiting rods 13 leave the corresponding limiting groove 10, so that the group away from the water pump 4 can rotate at this time, and then the incomplete gear 17 drives the group of rotating rods 9 and the ball valve 8 thereon to rotate, and the water storage space on the side away from the water pump 4 and the middle water storage space are released, so that the water flow can enter the middle water storage space, and then the incomplete gear 17 is released from the meshing with the group of gear bodies 11, and the rotating rod 9 rotates just one circle, so that the water storage space on the side away from the water pump 4 and the middle water storage space are re-closed, and at the same time, the squeezing amplitude of the eccentric wheel 18 on the corresponding limiting rod 13 gradually increases. Until the group of limiting rods 13 are inserted into the corresponding limiting grooves 10, the rotation of the group of rotating rods 9 is restricted again, and at this time the incomplete gear 17 has not started to mesh with the other group of gear bodies 11. Therefore, the middle water storage space is in a completely closed state at this time, so that the clean water can complete the static task in this space. After a period of time, the incomplete gear 17 rotates to start meshing with the gear body 11 close to the side of the water pump 4. As mentioned above, the squeezing amplitude of the corresponding eccentric wheel 18 on the corresponding limiting rod 13 is reduced, and the rotation restriction of the rotating rod 9 close to the side of the water pump 4 is released and drives the corresponding ball valve 8 to rotate one circle. In this process, the clean water that has been static flows from the upper and middle part into the water storage space close to the side of the water pump 4, and the water supply pump 4 continuously transports and sprays, and the above process is repeated continuously, so that the dust and impurity treatment task of the clean water can be further completed on the basis of filtration.

[0036] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
