[0034] like Figure 1 As shown, the continuous hydrolysis reaction tower device includes a lower cylinder mechanism, a main cylinder mechanism and an upper cylinder mechanism. The lower cylinder mechanism, the main cylinder mechanism and the upper cylinder mechanism are arranged in sequence from bottom to top. The lower cylinder mechanism is used to buffer the pantolactone hydrolysate feed. In this area, impurities in the pantolactone hydrolysate will precipitate and separate; the pantolactone hydrolysate fully reacts with the reaction enzyme bacteria pellets at the main cylinder mechanism; after the hydrolysis reaction is completed, the pantolactone hydrolysate enters the upper cylinder mechanism, separates from the reaction enzyme bacteria pellets and then flows out.

[0035] Among them, the lower cylinder mechanism includes a skirt cylinder 1, a lower head 2, a lower cylinder 3 and a lower conical shell 4. The lower cylinder 3 is fixedly installed by the skirt cylinder 1, and the lower head 2 is blocked at the lower end of the lower cylinder 3, and a sewage outlet is provided on the lower head 2. The large end of the lower conical shell 4 is sealed and connected with the upper end of the lower cylinder 3, and the inner cavity is connected. A plurality of lower cylinder liquid level gauges 5 are provided on the outer wall of the lower cylinder 3 for monitoring the liquid level in the lower cylinder 3. A lower cylinder manhole 6 is also provided on the outer wall of the lower cylinder 3 for equipment maintenance, cleaning, etc.

[0036] The main cylinder mechanism includes a main cylinder 10, a jacket 11 and a plurality of tray assemblies 9. The lower end of the main cylinder 10 is connected and sealed with the small end of the lower conical shell 4; the jacket 11 is sleeved on the outer side of the main cylinder 10 to form a closed insulation chamber between the two, and the insulation chamber has an insulation liquid inlet 7 and an insulation liquid outlet 14, which are respectively located at the lower end and the upper end of the insulation chamber.

[0037] A plurality of tray assemblies 9 are installed in the inner cavity of the main cylinder 10 and are spaced apart in the axial direction of the main cylinder 10; a reaction cavity for accommodating the reaction enzyme pellets is formed between two tray assemblies 9. The reaction enzyme pellets are immobilized enzyme particles of hydrolytic enzymes, which belong to the prior art. Figure 2-6 As shown, each tray assembly 9 includes a horizontal tray 20, a pellet retention tray 21 and a pellet baffle 22. The horizontal tray 20 is as shown in FIG. Figure 4 As shown, there are a plurality of first circulation channels 24 evenly distributed thereon, and the first circulation channels 24 may be straight through holes or other forms of structures; the cross-section of the holes may be any shape such as circular, elliptical, or elongated, as long as the liquid is allowed to flow from one side of the horizontal tower plate 20 to the other side.

[0038] The horizontal tray 20 has a blanking portion 23 for loading the reaction enzyme pellets; the blanking portion 23 allows the reaction enzyme pellets to fall from the upper side of the horizontal tray 20 to the lower side thereof under the action of gravity. The blanking portion 23 can be a through hole located inside the horizontal tray 20, or a groove located at the edge of the horizontal tray 20. Preferably, the blanking portion 23 is located at the edge of the horizontal tray 20 and is an arc-shaped groove; since the pantolactone hydrolyzate flows at the center of the main cylinder 10 and the disturbance is stronger than that at the edge, the blanking portion 23 is arranged at the edge of the horizontal tray 20, which not only does not affect the flow of the pantolactone hydrolyzate, but also can minimize the movement of the reaction enzyme pellets from the lower side of the horizontal tray 20 along the blanking portion 23 to the upper side of the horizontal tray 20.

[0039] At the same time, the positions of the drop parts 23 on the two adjacent horizontal tower plates 20 need to be staggered to avoid the reaction enzyme bacteria balls falling directly onto the lowest horizontal tower plate 20 when feeding, while there is no drop on other horizontal tower plates 20 or the reaction chambers between all horizontal tower plates 20 are filled with reaction enzyme bacteria balls.

[0040] In order to reduce the escape of reaction enzyme balls to the upper side of the horizontal plate 20, the ball retention plate 21 is fixedly installed at the blanking portion 23. When the blanking portion 23 is located inside the horizontal plate 20 and is a circular or other shaped through hole, the ball retention plate 21 is a cylindrical structure with two ends open and circumferentially closed, and a blanking channel is formed inside; when the blanking portion 23 is located at the edge of the horizontal plate 20 and is an open groove-like structure, the ball retention plate 21 is an open arc-shaped plate, and the ball retention plate 21 and the inner wall of the main cylinder 10 together form a blanking channel.

[0041] The pellet retention plate 21 extends to the upper and lower sides of the horizontal tower plate 20. The portion located on the upper side of the horizontal tower plate 20 can retain a certain amount of reaction enzyme pellets on the horizontal tower plate 20 when the reaction enzyme pellets are added from top to bottom; and the portion located on the lower side of the horizontal tower plate 20 can confine the reaction enzyme pellets to the lower area of ​​the horizontal tower plate 20 when the pantolactone hydrolyzate flows from bottom to top when the equipment is in use.

[0042] The specific connection structure of the horizontal tower plate 20 and the ball retention plate 21 is that the blanking part 23 has a clamping edge, the outer wall of the ball retention plate 21 is provided with a clamping part 26, and the clamping part 26 is provided with a clamping groove 25; the clamping edge extends into the clamping groove 25 and is fixedly installed by bolts, screws and other connecting parts.

[0043] Furthermore, the ball baffle 22 is slidably arranged on the inner side of the ball retention plate 21, and the shape of the ball baffle 22 is adapted to the structure of the blanking channel, for example, it is a cylindrical or curved plate. The density of the material of the ball baffle 22 is less than the density of the pantolactone hydrolyzate; when the pantolactone hydrolyzate is injected into the main cylinder 10, the ball baffle 22 floats up, thereby approaching or abutting against the lower side of the horizontal tower plate 20 on its upper side, and the reaction enzyme ball entering the blanking part 23 with the flow of liquid is trapped in the ball baffle 22, and will not continue to flow up with the pantolactone hydrolyzate. When there is no pantolactone hydrolyzate flowing in the main cylinder 10, the reaction enzyme ball falls back into the reaction chamber where it was originally located under the action of its own weight. The upper end of the ball baffle 22 has a limit table 28, which can cooperate with the upper edge of the ball retention plate 21, so as to limit the lowest position of the ball baffle 22.

[0044] Furthermore, the ball retention plate 21 is provided with a plurality of second flow channels 27, and the ball baffle plate 22 is provided with a plurality of third flow channels 29 to allow liquid to pass through the ball retention plate 21 and the ball baffle plate 22, but the reaction enzyme balls cannot pass through.

[0045] The lower end of the main cylinder 10 is provided with a hydrolyzate inlet 8, and the main cylinder 10 is also provided with a plurality of temperature measuring ports 12, which are evenly distributed in the axial direction of the main cylinder 10. A main cylinder manhole 13 is also provided on the side wall of the main cylinder 10 for equipment maintenance and feeding of reaction enzyme bacteria balls. Multiple main cylinder manholes 13 can be provided on the main cylinder 10 as needed.

[0046] The upper cylinder mechanism includes an upper conical shell 15, an upper cylinder 16, and an upper head 18. The small end of the upper conical shell 15 is sealed and connected to the upper end of the main cylinder 10, and the large end is sealed and connected to the upper cylinder 16; this structure is conducive to the sedimentation and fall of the reaction enzyme bacteria balls in the pantolactone hydrolyzate, and then realizes separation from the liquid, which can prevent the bacteria balls from being lost during the discharge process of the pantolactone hydrolyzate. The upper cylinder 16 is provided with a plurality of upper cylinder liquid level gauge ports 17 to monitor the material situation at the top of the tower during the reaction. The upper head 18 closes the upper end of the upper cylinder 16, and a hydrolyzate outlet 19 is provided on it.

[0047] Before the pantolactone hydrolysis reaction, the reaction enzyme bacteria balls required for production are first put into the tower through the main cylinder manhole 13, and the reaction enzyme bacteria balls will be evenly distributed on the horizontal tower plate 20.

[0048] After the addition of the reaction enzyme pellets is completed, the pantolactone solution is pumped in from the hydrolyzate inlet 8. As the pantolactone solution is pumped in, the pantolactone solution will fully contact the reaction enzyme pellets on the horizontal tray 20. As the pantolactone hydrolyzate flows upward, the reaction rate gradually increases. When the hydrolyzate outlet 19 is reached, the reaction is terminated and the reaction liquid is continuously extracted to enter the next step of separation of the reaction liquid.

[0049] During the hydrolysis reaction, the reaction temperature is controlled by controlling the flow rates of the insulation liquid inlet 7 and the insulation liquid outlet 14 of the jacket 11; the temperatures of the multiple temperature measuring ports 12 are observed, and the constant temperature water of the insulation liquid inlet 7 and the insulation liquid outlet 14 is fine-tuned, thereby controlling the continuous progress of the pantolactone hydrolysis reaction.
