Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of catalyst filters, in particular to a novel catalyst filter. Background Art
[0002] The slurry bed hydrogenation process is a hydrogenation reaction technology widely used in chemical production. This technology is based on a slurry bed reactor and hydrogen as a reducing agent. The chemical reaction process is carried out under high pressure, high temperature and catalyst, thereby achieving hydrogenation conversion of organic molecules.
[0003] The slurry bed reactor is a highly efficient reaction device with the advantages of high specific surface area, high catalytic activity and high hydrogenation reaction rate. In the slurry bed reactor, the catalyst and reactants enter the reactor simultaneously in the form of a suspension, and the organic molecules are hydrogenated and converted under the action of the catalyst to finally produce water-white hydrogenated petroleum resin. However, due to the filtration efficiency of the filter, there will be very little catalyst residue in the hydrogenated petroleum resin, which affects the final quality of the resin. The degree of catalyst filtration depends on the filtration procedure and filtration accuracy of the filter.
[0004] The existing catalyst filter uses a metal filter element with a certain filtration accuracy as a filter. The original catalyst filter only has a fixed filter element pore size, which intercepts catalyst particles of a certain particle size, but cannot intercept smaller particles in the catalyst, resulting in catalyst residues in the resin, affecting the quality of the catalyst. Based on this, it is very important to propose a new catalyst filter. Utility Model Content

DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] Figure 1 This is a schematic diagram of the overall appearance structure of the utility model, and combined with Figure 2As shown, the novel catalyst filter comprises an outer shell 1 and a slurry tank 2, a filter element 12 is arranged inside the outer shell 1, the filter element 12 is used to filter impurities or larger particles in the slurry, a monitoring device can be arranged in the catalyst accumulation area of the filter element 12, the monitoring device comprises a pressure sensor and a displacement sensor, and is used to monitor the catalyst thickness in the accumulation area, a slurry circulation component is arranged between the slurry tank 2 and the outer shell 1, the slurry circulation component comprises a first circulation pipe 3, a circulation pump 7, a third circulation pipe 11 and a discharge pipe, and the third circulation pipe 11 is connected to the feed end of the circulation pump 7 Between the lower end of the outer wall of the outer shell 1 and the slurry tank 2, one end of the first circulation pipe 3 is connected to the discharge end of the circulation pump 7, and the other end of the first circulation pipe 3 extends to the inner upper end of the outer shell 1, and the discharge pipe fitting is installed at the inner upper end of the outer shell 1, the discharge pipe fitting is located above the filter element 12, and the discharge pipe fitting is connected to the other end of the first circulation pipe 3. A solenoid valve (not shown) can be installed on the first circulation pipe 3, and the solenoid valve is used to adjust the flow rate of the slurry to control the speed and density of the catalyst accumulation. A second circulation pipe 8 is connected between the bottom end of the outer shell 1 and the slurry tank 2.
[0028] Among them, the discharge pipe includes a cross discharge pipe 13 and multiple discharge nozzles 14, one end of the cross discharge pipe 13 is connected to one end of the first circulation pipe 3 located inside the outer shell 1, and the multiple discharge nozzles 14 are evenly installed on the lower end surface of the cross discharge pipe 13.
[0029] Through the above technical solution:
[0030] During specific use, the circulation pump 7 can be started first, and the catalyst slurry in the slurry tank 2 can be extracted by using the third circulation pipe 11. The catalyst slurry enters the first circulation pipe 3 through the circulation pump 7, and then is sent to the discharge pipe through the first circulation pipe 3. It can flow out to the filter element 12 in an orderly manner through the multiple discharge nozzles 14 on the lower end face of the cross discharge pipe 13, and is preliminarily filtered through the filter element 12 to form a catalyst accumulation on the surface of the filter element 12. When it accumulates to a certain extent, a denser new filter element is formed to completely intercept the catalyst. The flowing catalyst slurry can flow back to the slurry tank 2 through the second circulation pipe 8. In this way, the continuous circulation of the catalyst slurry can be achieved, and the catalyst accumulation is formed on the surface of the filter element 12, which can improve the interception efficiency of the catalyst, improve the product quality, and further ensure the stable operation of the device.
[0031] The discharge from the discharge nozzles 14 in multiple directions facilitates the uniform accumulation of the catalyst slurry, thereby improving the overall catalyst interception effect.
[0032] In addition, see Figure 2 and Figure 3As shown, a cover 9 is detachably provided on one side of the outer shell 1, and an air supply pipe 10 is penetrated by the cover 9. The air inlet end of the air supply pipe 10 is used to connect to a compressed air source, and the compressed air source is used to provide high-pressure gas for backblowing.

The length of the spray tube 15 is equal to the length of the filter element 12, and the outer wall of the spray tube 15 is installed with multiple directional nozzles 16.
[0033] As can be seen from the above, after filtering for a certain period of time, when the catalyst accumulation on the filter element 12 reaches a certain level and affects the passing speed of the resin liquid, the catalyst accumulation can be destroyed by backblowing, and the cycle can be re-established to form an accumulation filter element and start a new round of filtration.
[0034] When back-blowing is performed, the compressed air source can be started to supply air to the air supply pipe 10, and the high-pressure air is sent to the spray tube 15 through the air supply pipe 10, and then sprayed out through multiple directional nozzles 16, which can destroy the catalyst accumulation on the filter element 12, thereby completing the back-blowing function.
[0035] See also Figure 4 As shown, a tank cover 4 is provided at the top of the slurry tank 2, a motor 5 is installed in the middle of the top of the tank cover 4, a connecting rod 19 is connected to the bottom of the motor 5, and multiple groups of stirring structures are installed outside the connecting rod 19.

[0037] Through the above technical solution:
[0038] When in use, the motor 5 can be started, and the output end of the motor 5 can be used to drive the connecting rod 19 to rotate, thereby driving the stirring rod 17 installed outside the fixed block 18 to rotate, so as to stir the catalyst slurry in the slurry tank 2 to avoid the deposition of the catalyst slurry.
[0039] Furthermore, a feeding pipe 6 is connected to the top of the tank cover 4 , and the feeding pipe 6 is connected to the inside of the slurry tank 2 .
[0040] As can be seen from the above, during use, the catalyst slurry can be added from the feed pipe 6, which is more convenient and practical.
