Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to a filtering device for a hydrocracking reactor. Background Art

[0002] The hydrocracking reactor is an important industrial equipment, mainly used to crack heavy oil or coal and other raw materials under hydrogenation conditions to produce light oil products or fuels. It cracks heavy molecules into lighter products through the hydrocracking reaction on the catalyst, and at the same time performs hydrogenation reaction to improve the stability and quality of the product.

[0003] In the processing steps of the hydrocracking reactor, filtration mainly occurs in the stage of raw material processing. During the raw material processing, the raw petroleum fraction or crude oil will undergo pretreatment operations such as desalting and desulfurization, and then be sent to the hydrocracking unit for heating and cracking. In this process, the raw materials may contain solid particles, impurities, etc. These impurities may have an adverse effect on the subsequent cracking reaction and the activity of the catalyst. In order to solve the above problems, the crude oil can be filtered before processing to remove impurities and solid particles therein, thereby ensuring the smooth progress of the hydrocracking reaction and the long-term stability of the catalyst. For this reason, we propose a filtering device for a hydrocracking reactor. Utility Model Content

[0025] See also Figure 1-4 A filtering device for a hydrocracking reactor comprises a filtering tank 1, a detachably connected sealing cover 2 is fixedly mounted on the top of the filtering tank 1, a discharge pipe 3 for discharging materials is provided at the bottom of the filtering tank 1, a closed ball valve 4 is rotatably mounted inside the discharge pipe 3, a feed pipe 5 for feeding materials is provided on the top of the sealing cover 2, and further comprises:

[0026] A separation assembly is arranged inside the filter tank 1. The separation assembly is used to filter crude oil containing impurities. The separation assembly includes a separation cover barrel 7, a sliding frame 8 and a collection cover 9. Two sets of sliding frames 8 are fixedly installed at equal intervals on the inner wall surface of the filter tank 1. The separation cover barrel 7 is rotatably installed between the two sets of sliding frames 8. A collection cover 9 for collecting is fixedly installed on the inner wall surface of the filter tank 1 at a position corresponding to the separation cover barrel 7. The sliding frame 8 penetrates the collection cover 9 and is fixedly installed with the collection cover 9;

[0027] The filter assembly is arranged at the bottom of the inner wall of the filter tank 1. The filter assembly is used to filter the separated crude oil. The filter assembly includes a fixed frame 13, a filter membrane 14 and a scraper 15. The fixed frame 13 is fixedly arranged at the bottom of the inner wall of the filter tank 1. The filter membrane 14 is fixedly arranged on the inner wall of the fixed frame 13. The scraper 15 for scraping is fixedly arranged at the position of the filter membrane 14 at the bottom of the fixed frame 13 corresponding to the filter membrane 14. Through the arrangement of the filter assembly, after the crude oil is separated and filtered through the separation cover barrel 7 and falls along the collection cover 9, it will fall on the top of the filter membrane 14. When the drive motor is started to drive the drive shaft 10 to rotate, the auxiliary slide bar 11 at the bottom of the drive shaft 10 will rotate synchronously, thereby squeezing the crude oil falling on the top of the filter membrane 14 to rub and squeeze with the filter membrane 14, so that the crude oil passes through the filter membrane 14 and is subjected to secondary filtration, thereby improving the purity and quality of the crude oil, and facilitating the processing and use of the crude oil in the hydrocracking reactor.

[0028] Furthermore, the feed pipe 5 passes through the sealing cover 2 and extends to the interior of the filter tank 1, and a guide pipe 6 for guiding is fixedly installed at the bottom of the feed pipe 5 at a position corresponding to the separation component.

[0029] Furthermore, the separation cover barrel 7 is a double-layer structure as a whole, the outside of the separation cover barrel 7 is a filter cover, and the inside of the separation cover barrel 7 is a connecting tube. A number of connecting rods for strengthening the connection are equidistantly fixedly installed on the inner wall surface of the filter cover, and the other ends of the connecting rods are fixedly installed on the outer wall surface of the separation cover barrel 7.

[0030] Furthermore, a driving motor is fixedly installed on the top of the sealing cover 2, and a driving shaft 10 is fixedly installed on the output end of the driving motor. An auxiliary sliding rod 11 is fixedly installed on the bottom of the driving shaft 10 at the position corresponding to the filter component, and the bottom of the auxiliary sliding rod 11 is in contact with the top of the filter component. Through the setting of the separation component, when in use, the driving motor is started to drive the driving shaft 10 to rotate through the driving motor, so that through the connection between the driving shaft 10 and the separation cover barrel 7, the separation cover barrel 7 is driven to rotate between the two sets of sliding frames 8, thereby driving the crude oil inside the separation cover barrel 7 to separate with the rotation of the separation cover barrel 7, and utilizing the centrifugal force generated by the crude oil in the rotational motion to separate impurities and particulate matter from the crude oil under the action of centrifugal force, thereby leaving the impurities inside the separation cover barrel 7, and the separated crude oil will flow out through the holes opened on the separation cover barrel 7 and be dispersed inside the collecting cover 9, and then through the convergence of the collecting cover 9, the separated crude oil will fall along the collecting cover 9 for the next processing.

[0031] Furthermore, a plurality of connecting rods 12 are fixedly installed at equal intervals inside the separation cover barrel 7 , and the separation cover barrel 7 is fixedly connected to the driving shaft 10 .

[0032] Instructions

[0033] When in use, firstly, the crude oil to be processed is injected into the filter tank 1 through the feed pipe 5. After being diverted by the guide pipe 6, the crude oil will fall into the separation cover barrel 7. At this time, the drive motor is started to drive the drive shaft 10 to rotate, thereby driving the separation cover barrel 7 to rotate between the two sets of sliding frames 8 through the connection between the drive shaft 10 and the separation cover barrel 7, thereby driving the crude oil in the separation cover barrel 7 to separate with the rotation of the separation cover barrel 7. The centrifugal force generated by the crude oil in the rotational motion is utilized to separate impurities and particulates from the crude oil under the action of centrifugal force, thereby leaving the impurities in the separation cover barrel 7, and the separated crude oil will flow out through the holes opened on the separation cover barrel 7 and be dispersed in the collection cover 9. Then, the separated crude oil will fall along the collection cover 9 through the convergence of the collection cover 9. After separation and filtration from the cover barrel 7 and falling along the collecting cover 9, it will fall on the top of the filter membrane 14. When the drive motor is started to drive the drive shaft 10 to rotate, the auxiliary slide bar 11 at the bottom of the drive shaft 10 will rotate synchronously, thereby squeezing the crude oil falling on the top of the filter membrane 14 to rub and squeeze the filter membrane 14, so that the crude oil passes through the filter membrane 14 and is filtered twice, thereby improving the purity and quality of the crude oil. When processing is needed, it is only necessary to rotate and open the ball valve inside the discharge pipe 3, and the crude oil after separation and filtration inside will be discharged from the discharge pipe 3, so that it can be used in subsequent processing. Through the mutual cooperation between the above-mentioned structures, the device can filter the crude oil before processing to remove impurities and solid particles therein, thereby ensuring the smooth progress of the hydrocracking reaction and the long-term stability of the catalyst, which is more convenient and practical.
