Description

Technical Field

[0001] This utility model relates to catalyst regeneration technology, specifically a catalyst regeneration reactor. Background Technology

[0002] A catalyst is generally a substance that can increase the reaction rate without changing the overall reaction standard. After a certain number of uses and time, catalysts are usually regenerated. The catalyst regeneration process does not involve the disintegration of the overall catalyst structure. A catalyst regeneration system is an industrial device or process system specifically designed to restore the activity of deactivated catalysts. Its core objective is to remove deactivation factors such as carbon deposits, poisons (such as sulfur and heavy metals), and sintering products from the catalyst surface through physical, chemical, or physicochemical methods, so as to restore the catalyst to its original catalytic performance, thereby extending its service life and reducing production costs.

[0003] Existing catalyst regeneration systems typically place the catalyst to be regenerated directly into the reactor. However, the catalyst to be regenerated is usually agglomerated and has a large volume. Therefore, the catalyst located inside the agglomerates is difficult to regenerate. Moreover, the catalyst to be regenerated usually adsorbs a large amount of water. This water not only leads to a decrease in catalyst activity, but also affects the regeneration temperature during the regeneration process, resulting in an increase in regeneration time and affecting regeneration efficiency.

The drying box 5 has a feed inlet 6 at the top and a discharge outlet 10 at the bottom, which is connected to the reactor 11. The feeding conveyor belt 4 is used to transport the catalyst discharged from the feed inlet 3 to the feed inlet 6. The drying box 5 is equipped with a mixing component for stirring the catalyst inside the drying box 5. The drying box 5 is connected to a drying pipe 16 for blowing in high-temperature dry air to dry the catalyst inside the drying box 5.

The crushing box 1 is fixed with a crushing motor. The crushing motor drives the transmission gear to rotate. The crushing motor drives the two transmission gears to rotate, so that the two crushing rollers 2 rotate towards each other, crushing the agglomerated catalyst and achieving the crushing effect. The crushing roller 2 can also have protrusions evenly distributed on it. Through the compression of the protrusions, large pieces of catalyst can be crushed, preventing the catalyst from slipping above the two crushing rollers 2.

[0026] The reactor 11 is provided with a discharge port, and a feeding conveyor belt 12 is provided below the discharge port. The feeding conveyor belt 12 is used to discharge the regenerated catalyst.

[0027] The mixing assembly includes a stirring motor 7 and a stirring shaft.

[0028] The bottom of the stirring shaft is provided with a scraper 9, and the bottom of the scraper 9 abuts against the bottom wall of the drying box 5; the scraper 9 can scrape the catalyst to the discharge port 10.

[0029] The top of the drying chamber 5 is equipped with an exhaust port, and the exhaust port is equipped with a filter screen.

[0030] The reactor 11 is provided with an inlet pipe 14 and an exhaust pipe 15. The exhaust pipe 15 is connected to the heat exchange box 13. The inlet pipe 14 and the drying pipe 16 both pass through the heat exchange box 13. The heat exchange box 13 is used to contain the high-heat waste gas discharged from the exhaust pipe 15. Through heat conduction, the gas in the inlet pipe 14 and the drying pipe 16 is heated to realize the waste heat utilization function.

[0031] The outer periphery of the section of the air inlet pipe 14 and the drying pipe 16 located inside the heat exchange box 13 is uniformly provided with several fins; the arrangement of the fins can increase the contact area between the drying pipe 16 and the air inlet pipe 14 and the high-heat exhaust gas, thereby improving the heat conduction efficiency.
