Description

Technical Field

[0001] The invention relates to the technical field of industrial waste gas treatment, in particular to waste gas pretreatment and separation equipment for RTO equipment. Background Art

[0002] RTO is a regenerative thermal oxidizer. Its principle is to oxidize organic matter (VOCs) in the exhaust gas into corresponding carbon dioxide and water at high temperature, thereby purifying the exhaust gas. This equipment is used to treat various organic waste gases generated in industrial production. The treatment method is usually to directly connect the exhaust source of the waste gas to the RTO equipment for direct treatment;

[0003] In industrial production, organic waste gas will carry some solid particles, so the solid particles in the waste gas will enter the RTO equipment for treatment together, which is very likely to cause solid particles to accumulate at the initial exhaust port of the RTO equipment and produce scale, while increasing the difficulty of waste gas treatment. Therefore, it is necessary to equip waste gas separation equipment to separate and filter the solid particles in the waste gas to ensure the stable and efficient waste gas treatment work.

[0004] A waste gas pretreatment separation device for RTO equipment is disclosed in a patent application with reference publication number CN116651135A. The separation device uses a condensing inner core and a particle filtering inner core arranged in an installation cylinder to first condense and drain the exhaust gas, and then filter and remove solid particles, thereby achieving preliminary filtration treatment of the organic waste gas, so that the organic waste gas entering the RTO equipment can avoid solid particle fouling during the treatment process.

[0005] The above separation device can well complete the separation and filtration of the exhaust gas through the particle filter core, avoiding the problem of solid particles fouling in the RTO device. However, after regular use, the particle filter core on the separation device still needs to be repeatedly disassembled and installed, which increases the maintenance workload, and the particle filter core cannot be automatically replaced, and the filter material cannot be quickly and actively replaced.

[0006] Furthermore, after a single replacement of the particle filter core is completed, the particle filter core needs to be repositioned to reset to a predetermined position, which is time-consuming and labor-intensive, increases the difficulty of subsequent maintenance, and increases labor input costs.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention is provided with an active cutting mechanism.

[0022] The present invention is provided with a limiting mechanism. Under normal conditions, the limiting frame and the fixing frame are close to each other to press the filter cloth, thereby ensuring the stability of the filter cloth. When the cutting plate completes cutting of a separation chamber, the linkage arm corresponding to the separation chamber on this side moves with the cutting plate. Since the initial height of the linkage arm is higher than the initial height of the guide sleeve, when the linkage arm is inserted into the corresponding guide sleeve, the guide sleeve and the limiting frame are driven to move upward as a whole, that is, the limiting frame is separated from the filter cloth, which facilitates the switching of the filter cloth and reduces the resistance. The movements of the two limiting frames are independent of each other and are not interfered with each other, thereby providing convenience for the switching of the filter cloth.

[0043] It is worth noting that: when separation is performed: by providing a switching separation mechanism, the filter cloth 102 is correspondingly wound on one of the winding shafts 101, and the other end of the filter cloth 102 passes through the separation chamber 1 and is wound on another winding shaft 101. At this time, the filter cloth 102 is in contact with the fixing frame 104 in the separation chamber 1, and the filter cloth 102 is restricted by the fixing frame 104 to prevent the filter cloth 102 from being damaged by the impact of the exhaust gas. At this time, the exhaust gas is introduced into the separation chamber 1 through the air inlet pipe 5 and then filtered and separated through the filter cloth 102. After that, the separated exhaust gas is discharged from the separation chamber 1 through the air outlet pipe 6, thereby completing the separation of the exhaust gas. At the same time, when the filter cloth 102 wound on the winding shaft 101 is used up, it is only necessary to replace the corresponding rolled filter cloth 102.

[0044] In the embodiment of the present invention, the two switching units 10 both include a take-up shaft 101 rotatably inserted into the two storage boxes 9, and a ratchet mechanism is installed between the take-up shaft 101 and the storage box 9, the ratchet mechanism consists of a ratchet and a pawl, the ratchet is fixedly sleeved on the outside of the take-up shaft 101, the pawl is installed on the storage box 9 through a torsion spring, the pawl contacts with the ratchet to complete the rotation restriction, and the rotation restriction direction of the ratchet and the pawl is matched with the one-way bearing 155, the ratchet mechanism is used to complete the stable restriction of the take-up shaft 101, when the take-up shaft 101 performs the filter cloth 102 switching action, the ratchet mechanism is unlocked to make the take-up shaft 101 rotate stably, on the contrary, when the take-up shaft 101 does not perform the filter cloth 102 switching action, the ratchet mechanism is locked to prevent the take-up shaft 101 from rotating, and the take-up shaft 101 and the storage box 9 are locked. The storage boxes 9 are detachably connected, a filter cloth 102 is wound on a take-up shaft 101 in one of the storage boxes 9, and two channels 103 are provided on both sides of the separation chamber 1 in cooperation with the two storage boxes 9, the filter cloth 102 passes through the channels 103 and is wound on the take-up shaft 101 in the other storage box 9, the filter cloth 102 passes through the separation chamber 1 for separation and filtration, and the filter cloth 102 and the take-up shaft 101 are detachably connected, a fixing frame 104 is detachably installed in the two separation chambers 1 by bolts, the fixing frame 104 is used to support and limit the filter cloth 102, and a plurality of ventilation zones are evenly provided on the fixing frame 104, the two storage boxes 9 are open on the side away from the separation chamber 1, and a sealing cover 105 is detachably sealed and installed on the open side of the two storage boxes 9 by bolts;

[0045] It is worth noting that when the filter cloth 102 is switched: by providing a switching unit 10, since two drive racks 153 are provided on the cutting plate 13, and the two drive racks 153 are respectively meshed with the drive gears 156 of the two separation chambers 1, and the linkage shaft 154 and the winding shaft 101 are unidirectionally restricted to rotate through a one-way bearing 155, when the cutting plate 13 moves toward one separation chamber 1 to complete the cutting, the two drive racks 153 are synchronously driven to move toward one side, and at this time, the winding on the separation chamber 1 on one side is about to be cut off. The shaft 101 is restricted in rotation by the one-way bearing 155 and completes transmission with the linkage shaft 154. At the same time, the reel shaft 101 of the separation chamber 1 on the other side is relatively rotated with the linkage shaft 154 by the one-way bearing 155, that is, the reel shaft 101 of the separation chamber 1 on the other side does not rotate, so that one of the reel shafts 101 on the two separation chambers 1 rotates and the other does not rotate, avoiding interference with the other separation chamber 1 when the filter cloth 102 of the separation chamber 1 on one side is switched, so the driving rack 153 is engaged with the driving gear 156 to complete the rotation of the reel shaft 101. , the filter cloth 102 wound on the other reel 101 is pulled and reeled up while the reel 101 is rotating, so that the clean filter cloth 102 is laid on the fixing frame 104 of the separation chamber 1 again to wait for the next separation work, so that the overall separation work can complete the continuous and uninterrupted filtering and separation work, without stopping to replace the filter cloth 102, and can complete the automatic switching of the filter cloth 102, with a high degree of automation, without manual replacement of the filter cloth 102, saving time and labor, and can complete the corresponding separation chamber during the process of the cutting plate 13 completing the cutting 1 filter cloth 102 is switched, on the contrary, when the separation chamber 1 on the other side needs to be cut off, the reel 101 on the separation chamber 1 that needs to be cut off is driven by the driving rack 153 and the driving gear 156 to complete the rotation to switch the filter cloth 102, and the reel 101 of the other separation chamber 1 is not subject to the transmission interference of the driving rack 153 and the driving gear 156 under the action of the one-way bearing 155, so that the switching of the filter cloth 102 in the two separation chambers 1 is relatively independent and does not interfere with each other, so that the switching of the filter cloth 102 is safe and stable.

[0046] Among them, electrical components such as the electric cylinder 14, the No. 1 electric regulating valve and the No. 2 electric regulating valve are all connected to switches through wires, and the switches are electrically connected to a controller, and the specific structure of the controller is not limited.

[0047] Embodiment 2: Based on the active cutting mechanism provided in Embodiment 1, this embodiment provides a further technical solution of the active cutting mechanism.

[0048] like Figure 2 , Figures 10 to 12As shown, the active cutting mechanism includes two limiting rods 11 symmetrically installed at the top and bottom ends of the back of the two separation chambers 1, and the two limiting rods 11 are detachably connected to the two separation chambers 1 through a bracket. A linkage plate 12 is slidably installed on the two limiting rods 11, and a cutting plate 13 is detachably installed on the lower surface of the linkage plate 12. One end of the cutting plate 13 extends to one of the separation chambers 1 to complete the blocking, and the other end of the cutting plate 13 is correspondingly slid through one side of the separation chamber 1. The cutting plate 13 can complete the blocking of one separation chamber 1, and a penetration area that cooperates with the cutting plate 13 is opened on the opposite side of the two separation chambers 1, and an electric cylinder 14 is installed on the back of one of the separation chambers 1 through a bracket, and the output end of the electric cylinder 14 is detachably fixedly connected to one side of the linkage plate 12, and a follower unit 15 is installed on the cutting plate 13, and the follower unit 15 is respectively connected to one of the winding shafts 101 of the two switching units 10. The corresponding winding shaft 101 is driven by the cutting plate 13 and the follower unit 15 to complete the active switching of the filter cloth 102;

[0049] It is worth noting that: when the separation chamber 1 is switched: an active cutting mechanism is provided, under normal conditions, the cutting plate 13 is extended to one separation chamber 1 to complete the blocking, and the other separation chamber 1 is in an open state. At this time, the separation chamber 1 in the open state can introduce the exhaust gas and separate and filter it. When the separation chamber 1 needs to be switched, it is only necessary to start the electric cylinder 14 to push the linkage plate 12 to move, and guide the linkage plate 12 through the limiting rod 11 to drive the cutting plate 13 to move out of one separation chamber 1 and insert it into the other separation chamber 1, thereby completing the active switching of the two separation chambers 1, which is convenient for free switching according to the use requirements, and in a single switching process, the filter cloth 102 of the separation chamber 1 on one side can be actively switched;

[0050] In the embodiment of the present invention, the follower unit 15 includes a fixed seat 151 installed on the top of the cutting plate 13, two driving arms 152 are symmetrically installed at the front end of the fixed seat 151, and driving racks 153 are fixedly installed at the tails of the two driving arms 152. A linkage shaft 154 is concentrically installed on the top of the winding shafts 101 that are far away from each other on the two switching units 10. A one-way bearing 155 is installed at the connection between the linkage shaft 154 and the winding shaft 101. The one-way bearing 155 completes the one-way restriction of the rotation direction of the linkage shaft 154. A driving gear 156 is fixedly sleeved on the outside of the linkage shaft 154. The winding shafts of the two switching units 10 The driving gear 156 on 101 is respectively meshed with the two driving racks 153, and the restricted rotation directions of the one-way bearings 155 on the winding shafts 101 of the two switching units 10 are opposite. When the cutting plate 13 moves toward the separation chamber 1 on the corresponding side to complete the blocking, the one-way bearing 155 on the winding shaft 101 corresponding to the separation chamber 1 is restricted in rotation to drive the winding shaft 101 to rotate to complete the switching of the filter cloth 102, and tracks 157 are detachably installed on the upper surfaces of the two top covers 4, and a slide seat 158 ​​is slidably engaged with the track 157. The slide seats 158 on the two top covers 4 are respectively detachably fixedly connected to the backs of the two driving arms 152.

[0051] Embodiment 3: Based on the limiting mechanism provided in Embodiment 1, this embodiment provides a further technical solution of the limiting mechanism.

[0052] like Figure 7 , Fig.14 and Fig.15 As shown, the limiting mechanism is composed of two pressing units 16 and two driving units 17. The two pressing units 16 are correspondingly installed in the two separation chambers 1. The filter cloths 102 in the two separation chambers 1 are actively pressed by the two pressing units 16. The two driving units 17 are correspondingly installed on the cutting plate 13. The two driving units 17 follow the action of the cutting plate 13 to drive the two pressing units 16. One of the driving units 17 follows the cutting plate 13 to insert into the corresponding pressing unit 16, and the other driving unit 17 follows the cutting plate 13 to move out of the corresponding pressing unit 16.

[0053] It is worth noting that: when limiting: by providing a limiting mechanism, under normal conditions, under the action of the four return springs 164, the limiting frame 163 is driven to move under the limit of the four guide rods 162, and the limiting frame 163 and the fixing frame 104 are driven to approach and press the filter cloth 102, thereby ensuring the stability of the filter cloth 102. At the same time, the two linkage arms 171 of the two driving units 17 are linked with the cutting plate 13. When the cutting plate 13 completes the cutting of one separation chamber 1, the linkage arm 171 corresponding to the separation chamber 1 on the side is connected with the cutting plate 13. As the cutting plate 13 moves, the linkage arm 171 is driven to be inserted into the guide sleeve 165 of the limiting frame 163 on the separation chamber 1. Since the initial distances of the linkage arm 171 and the guide sleeve 165 relative to the cutting plate 13 are different, that is, the initial height of the linkage arm 171 is higher than the initial height of the guide sleeve 165, when the linkage arm 171 is inserted into the corresponding guide sleeve 165, the guide sleeve 165 and the limiting frame 163 are driven to move upward as a whole, that is, the limiting frame 163 is separated from the filter cloth 102, which is convenient for the filter cloth 102 to be removed. The switching of the two separation chambers 1 also follows the cutting plate 13 to complete the linkage. The two limiting frames 163 move independently and are not interfered with each other, which provides convenience for the switching of the filter cloth 102. The separation work of the filter cloth 102 is compressed, and the separation work is ensured to be carried out stably. In order for the linkage arm 171 to be smoothly inserted into the guide sleeve 165, a slope 172 is provided on the side of the linkage arm 171 close to the guide sleeve 165. The linkage arm 171 is actively guided by the slope 172. At the same time, the linkage arm 171 is inserted into the guide sleeve 165 by the rotating wheel 173 to complete the rotational guidance, so that the linkage arm 171 is inserted into the guide sleeve 165 more smoothly, avoiding obstacles and reducing friction.

[0054] In the embodiment of the present invention, the two pressing units 16 each include four guide plates 161 distributed in a rectangular shape in the separation chamber 1, guide rods 162 are slidably penetrated on the four guide plates 161, plugs for limiting the movement of the limiting frame 163 are installed on the guide rods 162, and a limiting frame 163 is installed at the bottom of the four guide rods 162. The limiting frame 163 is correspondingly slidably installed in the separation chamber 1, and the limiting frame 163 and the fixing frame 104 are close to complete the pressing of the filter cloth 102.

[0056] The present invention provides an exhaust gas pretreatment separation device for RTO equipment, and the specific working principle is as follows: first, a No. 1 collecting pipe 7 is connected to the exhaust gas source, and then the exhaust gas is guided into the corresponding separation chamber 1 through the air inlet pipe 5. By arranging a switching separation mechanism in the separation chamber 1, the exhaust gas is filtered and separated from its impurities through the switching separation mechanism after entering the separation chamber 1, and then the filtered exhaust gas is sent to the lower-level processing equipment through the exhaust pipe 6 and the No. 2 collecting pipe 8, so as to complete the active interception and separation of the exhaust gas;

[0057] The exhaust gas separation equipment adopts a design of two separation chambers 1, and with the assistance of an active cutting-off mechanism, the active cutting-off mechanism can move in the two separation chambers 1 to complete targeted active cutting, so that one of the two separation chambers 1 is flowing and the other is closed, and the switching is flexible, which is convenient for switching and use according to needs. At the same time, when the active cutting-off mechanism is switched, the synchronous linkage switching unit 10 is actuated, so that the separation chamber 1 actively cut off by the cutting plate 13 completes the active switching of the filter cloth 102, that is, the clean filter cloth 102 is actively switched to the filtering and separation area, and no manual maintenance and replacement are required, which saves time and effort and reduces maintenance costs. Moreover, with the assistance of the limiting mechanism, under normal conditions, the limiting mechanism is used to press the filter cloth 102 in the separation chamber 1. At the same time, during the switching process of the active cutting-off mechanism, the limiting mechanism in the separation chamber 1 actively cut off by the cutting plate 13 is synchronously driven to move synchronously, so that the limiting mechanism on the side where the filter cloth 102 needs to be replaced moves, so that the limiting mechanism is separated from the filter cloth 102, so that the switching of the filter cloth 102 is smoother, the resistance is reduced, and it is convenient to use.
