[0002] Biological enzymes are organic substances with high catalytic activity produced by living cells. Most of them are proteins, and a very small part is RNA. Biological enzymes bind to substrates through specific structures to form enzyme-substrate complexes. Biological enzymes have been widely used due to their unique biological functions and high efficiency of enzyme catalysis. Immobilized enzymes are an enzyme application technology developed in the past decade or so, and have attractive application prospects in industrial production, chemical analysis, and medicine. After enzymes are immobilized, their stability is generally increased, they are easy to separate from the reaction system, and they are easy to control, can be used repeatedly, are easy to transport and store, and are conducive to automated production.

[0003] At present, in the process of processing the catalytic reaction of biological enzymes, the enzyme and substrate are generally put in all at once, and then the product is taken out through a one-time reaction and filtered and purified. Since the catalytic reaction is affected by many factors, a single catalytic number will directly lead to insufficient reaction, which will not only cause a waste of resources, but also result in the purity of the reactants failing to meet the specification requirements. Summary of the invention

[0007] As a preferred technical solution of the present invention, the reflux assembly includes a straight cylinder, a top plate is installed on the top of the straight cylinder, the top edge of the top plate is threadedly connected with bolts, the top plate is connected to the top surface of the reactor body by bolts, and the straight cylinder is provided with a hole on one side close to the top plate.

[0008] As a preferred technical solution of the present invention, the bottom end of the straight tube is connected to a flaring tube, and the flaring tube is located directly above the plurality of airbags.

[0009] As a preferred technical solution of the present invention, a circular hole is opened on the top surface of the top plate, a feeding assembly is arranged inside the circular hole, the feeding assembly includes a feeding barrel, the feeding barrel is inserted and connected to the inside of the circular hole, a sealing plug is threadedly connected to the top end of the feeding barrel, and a twist handle is installed on the top surface of the sealing plug.

[0010] As a preferred technical solution of the present invention, the bracket is located inside the straight tube.

[0011] As a preferred technical solution of the present invention, the partition plate includes a recessed circular plate, which is fixedly installed inside the reactor body. A cross opening is opened at the center of the top surface of the recessed circular plate, and the inner wall of the cross opening coincides with the outer wall of the inner tube and the airbag.

[0012] As a preferred technical solution of the present invention, an air pump is installed on one side of the outer wall of the reactor body, and the output end of the air pump extends into the interior of the reactor body and is connected to one end of the joint.

[0013] As a preferred technical solution of the present invention, a gathering opening is provided at the inner bottom end of the reactor body, and a discharge valve is connected to the bottom end of the gathering opening.

[0014] As a preferred technical solution of the present invention, support legs are respectively welded to the four corners of the bottom end of the reactor body.

[0015] In another aspect, the present invention provides a method for using an internal circulation catalytic reactor for a biological enzyme, comprising the following steps: S1. Adding raw materials: First, by holding the twist handle and twisting the sealing plug, the sealing plug is separated from the feed barrel, and then the same amount of reaction raw materials are injected into the feed barrels at different positions, and the sealing plug is twisted again to seal the feed barrel; S2. Blowing up the raw materials: while feeding, the air pump is started to inject air into the air guide tube from its output end until it is transported to the inside of the outer tube, and the air pressure inside the outer tube is increased to push the inner tube to extend upward until the inner tube drives the air bag to extend to the inside of the cross opening, and the air flow is continuously supplied to fill the entire cross opening, and the air hole is set so that the air flow inside the air bag can be released upward, thereby blowing up the raw materials accumulated on the partition board; S3, contact reaction: after the blowing in step S2, the stationary raw materials can be subjected to the upward airflow, thereby entering the inside of the expanded tube, and in conjunction with the connection of the straight tube, the raw materials following the upward airflow can contact the MBR membrane inside the straight tube and undergo a catalytic reaction; S4, reflux cycle: by opening a hole on one side of the straight cylinder, the raw material passing through the MBR membrane can pass through the straight cylinder and fall back onto the partition plate, and with the help of the rising airflow released by the blowing component, it enters the MBR membrane in the straight cylinder again, thus achieving the circulation activity law; S5, material discharge: after completing multiple cycles in step S4, the air pump is stopped so that the air flow is no longer supplied to the interior of the inner tube, and the inner tube is retracted to the interior of the outer tube through the elastic action of the spring on the inner tube. At the same time, since the airbag also lacks air flow supply, it will become deflated and detach from the cross opening, making the cross opening unobstructed up and down, causing the material after the catalytic reaction to fall to the gathering opening at the bottom of the reactor body, and then the discharge operation of the reactor is completed by opening the discharge valve.

[0016] Compared with the prior art, the present invention has the following beneficial effects: Through the mutual cooperation of the reflux component, MBR membrane, partition plate and blowing component, the reactor can achieve a more complete catalytic reaction of the raw materials, wherein, airflow is injected into the air guide tube through the output end of the air pump and transported to the inside of the outer tube, and the air pressure inside the outer tube is increased to push the inner tube to extend upward until the inner tube drives the airbag to extend to the inside of the cross opening, and prompts the airbag to fill the entire cross opening, and at the same time, with the setting of the air holes, the airflow inside the airbag can be released upward, thereby blowing up the raw materials accumulated on the partition plate, and driving the raw materials into the reflux component through the rising airflow, and contacting the MBR membrane for a preliminary catalytic reaction, and then by utilizing the hole setting in the reflux component, the raw materials that pass through the MBR membrane can fall back to the partition plate again, and thus be brought into the MBR membrane by the rising airflow for catalytic reaction again, thereby realizing the internal circulation function of the reactor.

[0026] Among them, an air pump 400 is installed on one side of the outer wall of the reactor body 100, and the output end of the air pump 400 extends to the interior of the reactor body 100 and is connected to one end of the connector 7008. Through the installation and use of the air pump 400, it supplies airflow to the blowing assembly 700.

[0027] A gathering opening is provided at the inner bottom of the reactor body 100 , and a discharge valve 900 is connected to the bottom of the gathering opening.

At the same time, since the airbag 7004 also lacks air flow supply, it will become shrunken and detach from the cross opening 8002, making the cross opening 8002 unobstructed up and down, causing the material after the catalytic reaction to fall to the gathering opening at the bottom of the reactor body 100, and then the discharge operation of the reactor is completed by opening the discharge valve 900.
