Its core feature is the use of porous ceramic filter tubes as a carrier to load catalysts, achieving integrated dust removal and chemical reaction treatment.

[0003] The utility model patent with patent authorization announcement number CN220126174U discloses a ceramic filter tube catalytic reactor, including a reaction vessel body and a ceramic outer tube. A partition layer is fixedly installed in the reaction vessel body, and the partition layer divides the reaction vessel body into two spaces, namely a first medium chamber and a second medium chamber. A connected ceramic outer tube is fixedly installed in the reaction vessel body, and the ceramic outer tube is located in the second medium chamber. An upper filter assembly is fixedly installed in the ceramic outer tube. A flow guiding structure is installed at the bottom of the upper filter assembly. A lower filter assembly is fixedly installed in the ceramic outer tube below the flow guiding structure.

[0004] However, existing ceramic filter tube catalytic reactors also have certain shortcomings. Although existing ceramic filter tube catalytic reactors use filter screens to pre-filter flue gas, the filter screens will become clogged after long-term use due to the adhesion characteristics of particulate impurities. Utility Model Content

[0005] The purpose of this invention is to provide an anti-clogging ceramic filter tube catalytic reactor, which solves the problem that existing ceramic filter tube catalytic reactors, although using filter screens to pre-filter flue gas, will cause filter screen clogging after long-term use due to the adhesion characteristics of particulate impurities.

A lower cover 4 is fixedly connected to the lower end of the reactor vessel 1. An outlet pipe 5 is fixedly connected to the inner wall of the lower cover 4. A mounting lug 6 is fixedly connected to the side of the upper cover 2. A mounting plate 7 is fixedly connected to the side of the reactor vessel 1, and the mounting plate 7 contacts the mounting lug 6. A nut 8 is fixedly connected to the lower end of the mounting plate 7. A bolt 9 is movably connected to the inner wall of the mounting lug 6, and the bolt 9 is movably connected to the mounting plate 7. The bolt 9 and the nut 8 are connected by threads. The bolt 9 and the nut 8 can be used to lock the mounting lug 6 and the mounting plate 7 together. An annular groove 10 is formed on the surface of the bolt 9.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 An end rod 11 is fixedly connected to the inner wall of the mounting plate 7. A movable plate 12 is slidably sleeved on the outer side of the end rod 11. The movable plate 12 is slidably connected to the mounting plate 7. A spring 13 is provided on the outer side of the end rod 11. One end of the spring 13 is welded to the mounting plate 7, and the other end of the spring 13 is welded to the movable plate 12. The movable plate 12 can be connected and used through the setting of the spring 13. An insertion rod 14 is fixedly connected to the inner wall of the movable plate 12. The insertion rod 14 is slidably connected to the annular groove 10. The bolt 9 can be inserted and limited through the cooperation of the insertion rod 14 and the annular groove 10.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5The reactor 1 is equipped with an anti-clogging filter mechanism 15, which includes a conveying pipe 150. The conveying pipe 150 is fixedly connected to the inner wall of the reactor 1. A suction pump 151 is installed on the outer side of the conveying pipe 150. A spray pipe 152 is fixedly connected to the upper side of the conveying pipe 150 and to the left of the suction pump 151. Two evenly distributed support rods 153 are fixedly connected to the inner wall of the reactor 1 and to the upper side of the conveying pipe 150. A motor 154 is fixedly installed on the end face of the two support rods 153. A squeezing rod 155 is fixedly connected to the output shaft of the motor 154. A fixing ring 156 is fixedly connected to the inner wall of the reactor 1. A movable ring 157 is slidably connected to the inner wall of the fixed ring 156. A filter screen 158 is fixedly connected to the inner wall of the movable ring 157. A limiting piece 161 is fixedly connected to the upper end of the fixed ring 156. A support piece 162 is fixedly connected to the inner wall of the reactor 1. A spring 163 is welded to the lower end of the support piece 162. The other end of the spring 163 is welded to the movable ring 157. With the installation of the suction pump 151 and the nozzle 152, the filter screen 158 can be cleaned by backflushing air. With the action of the motor 154, the extrusion rod 155 and other structures, the movable ring 157 can drive the filter screen 158 to shake back and forth, and perform auxiliary vibration to remove impurities from the filter screen 158.

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 The lower end of the movable ring 157 is fixedly connected to a protrusion 159, which contacts the extrusion rod 155. The protrusion 159 can be used to extrude the extrusion rod 155. The lower end of the fixed ring 156 is fixedly connected to a limiting piece 160, which contacts the movable ring 157. The limiting piece 160 can limit the contact of the movable ring 157.

[0027] The specific implementation process of this utility model is as follows: When in use, the filter screen 158 can be used to pre-filter out large particles in the input flue gas. With the cooperation of the suction pump 151 and the delivery pipe 150, air can be input into the nozzle 152 to perform air jet back cleaning on the filter screen 158.

[0028] The output shaft is driven by motor 154 to rotate, which in turn drives the extrusion rod 155 to rotate. The extrusion part of the extrusion rod 155 extrudes the protrusion 159, pushing the moving ring 157 upward along the inner wall of the fixed ring 156. This causes the second spring 163 to deform and the moving ring 157 to disengage from the first limiting piece 160. Finally, the moving ring 157 contacts the second limiting piece 161. When the extrusion rod 155 disengages from the protrusion 159, the second spring 163 returns to its original shape, pushing the moving ring 157 downward. This causes the filter screen 158 to move, and the moving ring 157 contacts the first limiting piece 160, vibrating the filter screen 158. This helps to clean the particulate impurities attached to the filter screen 158, ensuring the flowability of the filter screen 158 and preventing clogging.

[0029] By pulling the movable plate 12 away from the mounting plate 7, the movable plate 12 slides stably along the surface of the end rod 11, and the spring 13 deforms. When the movable plate 12 moves, it can drive the insertion rod 14 to move, and finally the insertion rod 14 is disengaged from the bolt 9, so that the bolt 9 can be removed, and then the upper cover 2 can be disassembled, which is convenient for operators to regularly and thoroughly clean the particulate impurities accumulated inside the reactor 1.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
