[0016] Beneficial effects

[0017] This invention provides an adjustable acid-base spray structure and its straw hydrolysis reactor. It has the following beneficial effects:

[0018] 1. This adjustable acid-base spray structure and its straw hydrolysis reactor allows for adjustment of the position of the infusion holes by rotating a claw disc within the outer shell. When the infusion hole aligns with one of the distribution holes, the infusion pipe can deliver the liquid material to the corresponding first, second, or third spray element. Different heights and positions of the first, second, and third spray elements achieve zoned spraying, improving the uniformity of hydrolysis. The infusion pipe connects to a pump that transports the material; rotating the claw disc adjusts the spray position, allowing for precise matching of the hydrolysis stage (initial acidic penetration → mid-stage alkaline neutralization) to promote straw hydrolysis. The structure is rationally designed, featuring three layers of ring spray elements with decreasing diameters and vertically equidistant distribution, achieving three-dimensional coverage within the reactor. A rotary fluid distributor with a sealed rotating structure between the claw disc and the outer shell controls the switching of spray layers through a single-hole alignment mechanism.

[0026] An adjustable acid-base spray structure and its straw hydrolysis reactor, such as Figure 2 and Figure 3 As shown, it includes:

[0027] The first spray element 11, the second spray element 12, and the third spray element 13 form a ring with decreasing diameter, and the first spray element 11, the second spray element 12, and the third spray element 13 are vertically and equally spaced.

[0028] like Figure 2 , Figure 4 and Figure 5 As shown, the distribution structure is set above the first spray element 11 for conveying materials to the first spray element 11, the second spray element 12, and the third spray element 13. The distribution structure includes a housing 20, a claw plate 21, a distribution hole 22, and an infusion hole 23. The claw plate 21 is rotatably connected to the housing 20. The housing 20 has several distribution holes 22, each of which is connected to the first spray element 11, the second spray element 12, and the third spray element 13 respectively. The claw plate 21 has an infusion hole 23, which can be rotated to adjust the infusion hole 23 to align with one of the distribution holes 22. The distribution structure also includes an infusion tube 24. The infusion tube 24 is fixedly installed at the top center of the claw plate 21. The infusion hole 23 extends to the end of the infusion tube 24 and is connected to the infusion tube 24. The housing 20 is a cylindrical structure, and a sealing ring is fixedly provided on the inner wall of the housing 20. The claw plate 21 is a circular plate adapted to the housing 20 and is rotatably set inside the cavity of the housing 20.

[0029] In this design, the position of the infusion port 23 is adjusted by rotating the claw disc 21 within the housing 20. When the infusion port 23 aligns with one of the distribution ports 22, the infusion pipe 24 can deliver the liquid material to the corresponding first spray element 11, second spray element 12, or third spray element 13. By using the first spray element 11, second spray element 12, and third spray element 13 at different heights and positions, zoned spraying is achieved, improving the uniformity of hydrolysis. The infusion pipe 24 is connected to a pump for conveying the material; rotating the claw disc 21 allows for... The spray position can be adjusted according to the degree of hydrolysis, precisely matching the hydrolysis stage of the material (initial acidic penetration → mid-term alkaline neutralization) to promote the hydrolysis of straw. The structure is reasonably designed, with three layers of circular spray elements with decreasing diameter and vertical equidistant distribution to achieve three-dimensional coverage inside the reactor. Rotary fluid distributor: The sealed rotating structure of the claw plate 21 and the outer shell 20 controls the switching of spray layers through a single-hole alignment mechanism. Integrated infusion channel: The central infusion pipe 24 is directly connected to the claw plate 21, simplifying the pipeline layout.

[0030] like Figure 5As shown, the distribution structure also includes a gear ring 25 and a motor 26. The gear ring 25 is fixedly connected to the claw disk 21, and the motor 26 is located above the claw disk 21. The output shaft of the motor 26 is fixedly mounted with a gear that meshes with the gear ring 25. The motor 26 can drive the claw disk 21 to rotate and adjust the position of the infusion hole 23. The motor 26 can be a servo motor. The motor 26 needs to be connected to a controller. The rotation angle of the output shaft of the motor 26 is limited by the controller coding, thereby ensuring the accuracy of the alignment between the infusion hole 23 and the distribution hole 22. The output shaft of the motor 26 drives the gear to rotate, and the gear moves the gear ring 25 to make the claw disk 21 rotate, thereby adjusting the position of the infusion hole 23. Adjusting the liquid sprayed by one of the first spray component 11, the second spray component 12, or the third spray component 13 is simple and quick, and automatic control can be achieved.

[0031] like Figure 2 and Figure 3 As shown, the outer casing 20 is fixedly equipped with a first connector 14, a second connector 15, and a third connector 16. The first connector 14, the second connector 15, and the third connector 16 are respectively located in two distribution holes 22. The first connector 14 is connected to the first spray element 11, the second connector 15 is connected to the second spray element 12, and the third connector 16 is connected to the third spray element 13. The first spray element 11, the second spray element 12, and the third spray element 13 are hollow inside and each has a spray hole at the bottom. The first spray element 11 is located above the second spray element 12, and the third spray element 13 is located below the second spray element 12. The diameter of the first spray element 11 is larger than the diameter of the second spray element 12, and the diameter of the second spray element 12 is larger than the diameter of the third spray element 13. The corresponding pipes are connected to the first spray element 11, the second spray element 12, and the third spray element 13 respectively to realize the branch delivery of liquid and ensure the accuracy and controllability of the spray position.

[0032] like Figure 1 and Figure 2 As shown, a straw hydrolysis reactor includes a reaction vessel 10. A feed pipe for feeding is fixedly installed on the top of the reaction vessel 10, and a discharge pipe for discharging is fixedly installed on the bottom of the reaction vessel 10. The reaction vessel 10 is equipped with all the aforementioned adjustable acid-base spray structures. The first spray element 11, the second spray element 12, and the third spray element 13 are all fixedly installed on the inner wall of the reaction vessel 10. The outer shell 20 and the motor 26 are fixedly installed on the top of the reaction vessel 10. By setting the above structure, the spray position can be precisely controlled when the entire device hydrolyzes straw, ensuring the full reaction of the straw.

[0033] The working principle of this utility model is as follows: The output shaft of the motor 26 drives the gear to rotate, and the gear moves the toothed ring 25 to make the claw disk 21 move in a circle, which can adjust the position of the infusion hole 23. When the infusion hole 23 is aligned with one of the distribution holes 22, the infusion pipe 24 can transport the liquid material to the corresponding first spray member 11, second spray member 12 or third spray member 13. The corresponding pipeline is connected to the first spray member 11, second spray member 12 and third spray member 13 respectively to realize the branch delivery of liquid. By using the first spray member 11, second spray member 12 and third spray member 13 with different heights and positions, the first spray member 11, second spray member 12 and third spray member 13 can achieve zoned spraying, and the straw in the reaction vessel can react with the liquid and hydrolyze.
