Technical Field

[0001] This invention relates to the field of waste sludge treatment technology, specifically to an enzymatic hydrolysis reactor structure for preparing carbon sources from waste sludge. Background Technology

[0002] Wastewater sludge is a solid waste generated during wastewater treatment, and its resource utilization is an important research direction in the current environmental protection field. Preparing carbon sources from wastewater sludge through enzymatic hydrolysis can achieve both sludge reduction and resource recovery, providing a low-cost carbon source for wastewater treatment systems, with significant economic and environmental benefits.

[0003] However, existing enzymatic hydrolysis reactors suffer from numerous technical challenges in treating waste sludge. Waste sludge is characterized by high viscosity and a tendency to agglomerate, resulting in low mixing levels between sludge and enzyme solution in traditional mixing devices and low carbon source conversion rates. Furthermore, enzyme solution is often added via single-point or top spraying, making it difficult for the enzyme solution to penetrate the pores within the sludge, leading to wasted enzyme activity and low reaction efficiency.

After the enzyme solution is sprayed out under high pressure by the conveying nozzle, it can quickly penetrate into the core area of ​​the sludge through the rectangular slot on the rotating cylinder. This reduces the enzyme solution accumulation and waste caused by traditional single-point addition, improves the enzyme solution utilization rate, and enhances the contact effect between the enzyme solution and the internal pores of the sludge, further ensuring the sufficiency of the enzymatic hydrolysis reaction. (4) This scheme can directly heat the sludge at the bottom of the tank by setting the electric heating wire on the side wall of the tank near the bottom, which can quickly increase the temperature of the reaction system and provide a suitable temperature environment for the enzymatic hydrolysis reaction. Moreover, the heating position is close to the reaction material, so the heat loss is smaller. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-10 This invention provides an enzymatic hydrolysis reactor structure for preparing carbon sources from waste sludge, comprising: Tank 1 has a feeding assembly installed on one side, which includes an installation pipe 101 and a feed pipe 102. An electric heating wire 105 is fixedly installed on the side wall of tank 1, located near the bottom. The installation pipe 101 and the feed pipe 102 work together to achieve orderly conveying of the remaining sludge, reducing sludge leakage or accumulation during feeding. The electric heating wire 105 is located near the bottom of the side wall of tank 1, which can directly heat the sludge at the bottom of the tank, quickly increase the temperature of the reaction system, provide a suitable temperature environment for the enzymatic hydrolysis reaction, and the heating position is close to the reactants, resulting in less heat loss. The stirring mechanism is installed inside the tank 1. Through a first gear 402, a second gear 406, and a rotating cylinder 401 with toothed grooves 408, the stirring mechanism can perform dual-mode stirring, including revolution and rotation, achieving a graded stirring effect. It should be noted that the first gear 402, as the core component for power transmission, works with the second gear 406 and the toothed grooves 408 on the inner wall of the rotating cylinder 401 to form a gear transmission structure, realizing the linkage between the revolution and rotation of the stirring components. The dual-mode stirring can adjust the stirring intensity according to the sludge dispersion state, which can reduce damage to enzyme activity while efficiently breaking up sludge aggregates. The graded stirring effect ensures full contact between the sludge and the enzyme solution, improving the efficiency of the enzymatic hydrolysis reaction. The feeding component is installed on the side wall of the tank 1. The feeding component adds materials into the tank 1 by moving the conveying nozzle 306. The anti-clogging mechanism is installed at the bottom of the mixing mechanism. Using a screw 502, it conveys excessive sludge upwards from the bottom, ensuring optimal reaction efficiency. Specifically, the screw 502 addresses the issue of residual sludge easily settling at the bottom of the tank. By conveying the accumulated sludge upwards, it reduces the risk of incomplete enzymatic hydrolysis caused by prolonged stagnation of the bottom sludge, while also minimizing clogging at the discharge port. This ensures smoother equipment operation and guarantees that all sludge in the entire reaction system participates in the enzymatic hydrolysis reaction, thereby improving carbon source conversion rate.

[0020] In some embodiments, see Figure 3 , Figure 4 , Figure 5The stirring mechanism includes a rotating shaft 403, a baffle 407, a second electric push rod 409, a fixed rod 410, a first stirring element 411, and a second stirring element 412. A rotating cylinder 401 is rotatably connected inside the tank 1. The baffle 407 is fixedly installed on the inner wall of the rotating cylinder 401 near the top. The baffle 407 is an annular plate. A toothed groove 408 is formed on the inner wall of the rotating cylinder 401, located at the top of the baffle 407. A first gear 402 is installed at the center inside the tank 1, and a second gear 406... A second gear 406 is rotatably connected to the top of the baffle 407. It is located between the first gear 402 and the rotating cylinder 401, meshing with the first gear 402 and the tooth groove 408. At least three second gears 406 are provided. A second electric push rod 409 is installed inside the second gear 406. A through hole 413, matching the output end of the second electric push rod 409, is provided on the top of the inner wall of the tank 1. Several through holes 413 are provided, arranged in a ring on the inner wall of the tank 1. At the top, a rotating shaft 403 is fixedly installed at the bottom of the first gear 402, and a first stirring element 411 is fixedly installed on the side wall of the rotating shaft 403. Several first stirring elements 411 are provided. A fixing rod 410 is fixedly installed at the bottom of the second gear 406, and a second stirring element 412 is fixedly installed on the side wall of the fixing rod 410. The first stirring elements 411 and the second stirring elements 412 are staggered. It should be noted that the rotating shaft 403 drives the first stirring elements 411 to achieve stirring in the central area, and the fixing rod 410 drives the second stirring elements 412 to rotate on their own axis while revolving around the second gear 406. The staggered distribution of the first stirring elements 411 and the second stirring elements 412 can cover the entire space inside the tank, reducing the stirring dead zone. The baffle 407 provides a stable mounting support surface for the second gear 406, ensuring the smoothness of gear transmission. The second electric push rod 409 cooperates with the through hole 413, and the rotating cylinder 401 can be fixed or unlocked by extending and retracting the push rod, flexibly switching the stirring mode to adapt to the stirring needs of different reaction stages.

[0021] In some embodiments, see Figure 3 , Figure 7 The fixed rod 410 has an installation cavity 414. The second electric push rod 409 is fixedly installed on the top of the installation cavity 414. A power supply device is fixedly installed in the installation cavity 414. A wire 415 is fixedly installed at the output end of the power supply device. The other end of the wire 415 is connected to the second electric push rod 409. It should be noted that the installation cavity 414 provides a sealed installation space for the second electric push rod 409 and the power supply device, reducing the possibility of sludge or enzyme solution corroding electrical components and ensuring the service life of the equipment. The power supply device provides stable power to the second electric push rod 409 through the wire 415, ensuring reliable operation of the electric push rod and achieving precise switching of the stirring mode.

[0022] In some embodiments, see Figure 1 , Figure 3A servo motor 4 is fixedly installed on the top of the tank 1. A first gear 402 is fixedly installed on the output end of the servo motor 4. The first gear 402 is rotatably connected to the inside of the tank 1 through the servo motor 4. The servo motor 4 is located at the center of the top of the tank 1. It should be noted that the servo motor 4 provides a power source for the stirring mechanism. Its output speed can be precisely adjusted to meet the speed requirements of different stirring stages. The servo motor 4 is installed at the center of the top of the tank 1 to ensure that the first gear 402 is subjected to uniform force, driving the entire stirring mechanism to run smoothly and improving the stability and controllability of the stirring process.

[0023] In some embodiments, see Figure 3 , Figure 6 , Figure 9 , Figure 10 The feeding assembly includes a storage tank 3, a connecting box 301, and a first electric push rod 305. The storage tank 3 is fixedly installed on the side wall of the tank body 1, located on one side of the electric heating wire 105. The connecting box 301 is fixedly installed on the top of the storage tank 3, and a connecting groove 304 is provided inside the connecting box 301, through which the connecting box 301 communicates with the storage tank 3. The first electric push rod 305 is fixedly installed on the inner wall of the storage tank 3, and the conveying nozzle 306 is fixedly installed on the first electric push rod. At the output end 305, a connecting hole 307 is provided on the inner wall of the tank 1, which is connected to the storage box 3. The conveying nozzle 306 is located inside the connecting hole 307. A connecting feeding port 308 is provided on one side of the conveying nozzle 306. A through slot 405 is provided on the side wall of the rotating cylinder 401. The slot 405 is rectangular. A sliding groove 404 is provided on the side wall of the rotating cylinder 401 to fit the conveying nozzle 306. A locking device is provided at one end of the sliding groove 404 to fit the conveying nozzle 306. It should be noted that the storage tank 3 is used to store enzyme solution. The connecting tank 301 replenishes the storage tank 3 with enzyme solution through the connecting tank 304 to ensure the continuity of feeding. The first electric push rod 305 drives the conveying nozzle 306 to move along the connecting hole 307. The slide 404 provides a moving guide for the conveying nozzle 306. The slot 4041 can fix the position of the conveying nozzle 306 when it is extended, so that the conveying nozzle 306 can fix the position of the rotating cylinder 401 after it is extended. When enzyme solution needs to be added, the first electric push rod 305 drives the conveying nozzle 306 to retract into the connecting hole 307 and be flush with the inner wall of the tank 1. At this time, the rotating cylinder 401 is no longer restricted and can rotate. At the same time, the feeding port 308 will be located in the storage tank 3, so that the enzyme solution in the storage tank 3 can be conveyed to the tank 1 through the conveying nozzle 306. The rectangular slot 405 facilitates the rapid entry of the enzyme solution sprayed from the conveying nozzle 306 into the interior of the rotating cylinder 401, so as to fully contact the sludge and improve the mixing efficiency.

[0024] In some embodiments, see Figure 1 , Figure 6A booster pump 302 is fixedly installed on the side wall of the connecting box 301. The output end of the booster pump 302 is connected to the connecting box 301. A feed pipe 303 is fixedly installed on the top of the connecting box 301. It should be noted that the booster pump 302 provides power for the enzyme solution delivery, ensuring that the enzyme solution sprayed from the delivery nozzle 306 has sufficient pressure, thereby enhancing the penetration ability of the enzyme solution into the sludge. The feed pipe 303 facilitates the replenishment of enzyme solution into the connecting box 301, making operation convenient and ensuring the continuous operation of the feeding component.

[0025] In some embodiments, see Figure 2 , Figure 8 The anti-blocking mechanism includes a movable rod 5, a sealing plate 501, a feeding plate 503, a connecting rod 505, a limiting member 506, and a rotating disk 508. The connecting rod 505 is fixedly installed on the top of the movable rod 5. A movable groove 504 is opened at the bottom of the rotating shaft 403. The rotating disk 508 is rotatably connected in the movable groove 504. A tension spring 510 is fixedly installed at the bottom of the rotating disk 508. The other end of the tension spring 510 is fixedly installed on the top of the limiting member 506. The connecting rod 505 is located in the movable groove 504. The limiting member 506 is fixedly installed on the top of the connecting rod 505. A limiting groove 507 that matches the limiting member 506 is opened on the inner wall of the movable groove 504. A spiral member 502 is fixedly installed on the side wall of the movable rod 5. A feeding plate 503 is fixedly installed on the surface of the spiral member 502. Several feeding plates 503 are provided. A protrusion 509 is fixedly installed on the side wall of the disc 508. The end faces of the limiting member 506 and the limiting groove 507 are both hexagonal. It should be noted that the movable rod 5 drives the screw 502 and the feeding plate 503 to rotate. The feeding plate 503 enhances the feeding capacity of the screw 502 and efficiently transports the sludge accumulated at the bottom. The connecting rod 505 connects the movable rod 5 and the limiting member 506. The hexagonal limiting member 506 cooperates with the limiting groove 507 to ensure that the power of the rotating shaft 403 can be stably transmitted to the movable rod 5. The tension spring 510 can adaptively adjust the height of the movable rod 5 according to the amount of sludge accumulation to reduce the damage to the screw 502 caused by overload. The rotating disc 508 and the protrusion 509 ensure the rotational flexibility in the movable groove 504. The sealing plate 501 prevents sludge from entering the interior of the movable groove 504 and reduces component jamming.

[0026] In some embodiments, see Figure 1 , Figure 2The installation pipe 101 is fixedly installed on the side wall of the tank 1 and is connected to the tank 1. The feed pipe 102 is fixedly installed on the top of the installation pipe 101 and is connected to the installation pipe 101. A cylinder 103 is fixedly installed on the inner wall of the installation pipe 101. A sealing element 104 is fixedly installed at the output end of the cylinder 103. One end of the sealing element 104 fits into the inner wall of the tank 1. It should be noted that the cylinder 103 drives the sealing element 104 to move, thereby opening or closing the connection between the installation pipe 101 and the tank 1. It opens when feeding and closes when reacting, ensuring the sealing of the tank 1. The sealing element 104 fits into the inner wall of the tank 1 to ensure the sealing effect, reduce the leakage of sludge or gas during the reaction, and reduce the entry of external impurities into the tank, which may affect the reaction effect.

[0027] In some embodiments, see Figure 1 , Figure 2 A discharge pipe 2 is fixedly installed at the bottom of the tank body 1, and a solenoid valve 201 is fixedly installed at the bottom of the discharge pipe 2. The discharge pipe 2 is funnel-shaped, and the spiral component 502 is located inside the discharge pipe 2. It should be noted that the funnel-shaped discharge pipe 2 facilitates the collection and discharge of enzymatic hydrolysis products, reducing residues; the solenoid valve 201 can precisely control the timing and speed of discharge, ensuring that discharge is carried out only after the reaction is complete; the spiral component 502 is located inside the discharge pipe 2 and can directly act on the sludge at the discharge port, effectively reducing the blockage of the discharge pipe 2 and ensuring smooth discharge.

[0028] The workflow and principle of this invention are as follows: First, residual sludge is introduced into the installation pipe 101 through the feed pipe 102. The cylinder 103 is activated to drive the sealing component 104 to move, opening the connection between the installation pipe 101 and the tank 1. The sludge enters the tank 1. After feeding is completed, the cylinder 103 drives the sealing component 104 to reset, closing the connection. Enzyme solution is added into the connecting box 301 through the feeding pipe 303. The enzyme solution enters the storage tank 3 through the connecting groove 304. The booster pump 302 is activated to increase the pressure. At the same time, when enzyme solution needs to be added, the first electric push rod 305 drives the conveying nozzle 306 to retract into the connecting hole 307, flush with the inner wall of the tank 1. The rotating drum 401 is unrestricted and can rotate, while the feeding port 308 is located in the storage tank 3, allowing the enzyme solution in the storage tank 3 to be transported to the tank 1 through the conveying nozzle 306. The rectangular slot 405 facilitates the rapid entry of the enzyme solution sprayed from the conveying nozzle 306 into the rotating drum 401, ensuring full contact with the sludge. Here, the power supply device in the mounting cavity 414 powers the second electric push rod 409. The output end of the second electric push rod 409 extends out and is embedded in the through hole 413, fixing the second gear 406 so that the fixed rod 410 only rotates on its own axis. Then, the first electric push rod 305 drives the conveying nozzle 306 to move along the connecting hole 307. The chute 404 provides a moving guide for the conveying nozzle 306, and the slot 4041 can fix the position of the conveying nozzle 306 when it is extended, so that the conveying nozzle 306 can fix the position of the rotating cylinder 401 after it is extended. The servo motor 4 is started to drive the first gear 402 to rotate. The first gear 402 meshes with the tooth groove 408 on the inner wall of the rotating cylinder 401 through the second gear 406. When the rotating cylinder 401 is in a fixed state, it drives the fixed rod 410 and the second stirring element 412 to revolve and rotate. The first gear 402 drives the rotating shaft 403 and the first stirring element 411 to rotate, realizing graded mixing, so that the sludge and enzyme solution are fully mixed. Mix, start the electric heating wire 105, and adjust the temperature inside the tank 1 to a suitable range for enzymatic hydrolysis. During the reaction, if sludge accumulates at the bottom, it will drive the screw 502 to move downward under the action of gravity. At the same time, the movable rod 5 and the connecting rod 505 will move downward. When too much sludge accumulates, the limiting part 506 will be stuck in the limiting groove 507. At this time, the rotating shaft 403 can drive the movable rod 5 to rotate through the limiting part 506 and the connecting rod 505. The screw 502 and the feeding plate 503 will transport the sludge at the bottom upward to reduce accumulation. After the enzymatic hydrolysis reaction is completed, open the solenoid valve 201, and the enzymatic hydrolysis product will be discharged through the funnel-shaped discharge pipe 2.
