Description

Technical Field

[0001] This utility model belongs to the field of environmental engineering technology, specifically a continuous focused ultrasonic reactor. Background Technology

[0002] An ultrasonic reactor is a reactor that utilizes ultrasound to enhance various chemical processes and is widely used in industries such as environmental remediation. It mainly consists of three parts: an ultrasonic generator, an ultrasonic transducer, and a reactor. The ultrasonic generator is an electrical signal device that generates ultrasonic frequencies; the ultrasonic transducer is a device that converts the electrical energy output from the generator into ultrasonic vibrations; the intense cavitation and thermal effects generated by the ultrasonic transducer occur within the reactor chamber.

[0003] Currently, conventional sonochemical reactors mainly consist of ultrasonic probe-type and ultrasonic tank-type reactors. These reactors suffer from significant acoustic impedance differences between the reactor and the liquid, resulting in high sound intensity near the probe and low sound intensity further away, severe sound wave reflection, and frequent energy loss. Furthermore, temperature control within the tank is difficult, hindering industrial-scale scaling. Moreover, the surface of the vibrator placed inside the reactor experiences severe erosion over time, with corrosion products contaminating the liquid within the reactor chamber and reducing cavitation efficiency. In contrast, cavity-type ultrasonic reactors using piezoelectric ultrasonic transducers avoid contact between the transducer and the processing liquid, preventing contamination and corrosion, and offering a longer service life. However, the distance and isolation between the piezoelectric ultrasonic transducer and the medium in the reaction chamber result in less pronounced vibration, lower sound field intensity, and poor energy dispersion, leading to energy loss and poor cavitation bubble activity.

[0004] Therefore, it is necessary to design a continuous ultrasonic reactor with energy-concentrating effect. To this end, this utility model provides a continuous ultrasonic reactor with energy-concentrating effect. Utility Model Content

[0016] Preferably, a connecting plate is fixedly and detachably installed at the output end of the connecting tee pipe, a connecting cylinder is detachably installed on the bottom surface of the connecting plate, and a storage cylinder is elastically installed on the inner wall of the connecting cylinder.

[0040] The reaction container 3 is a regular hexagon made of stainless steel, with a side length of 8-9 cm and a height of 70-80 cm.

[0041] Multiple ultrasonic transducers 6 are provided, and the multiple ultrasonic transducers 6 are evenly arranged on the outer wall of the reaction container 3. The ultrasonic transducers 6 are connected in series and connected to the ultrasonic generator 7.

[0044] The filtration assembly includes a filter screen 5, which is fixedly installed at one end of the material outlet 4 of the ultrasonic reactor. The ultrasonic transducer 6 of the ultrasonic reactor has an ultrasonic emission frequency of 25kHz and an ultrasonic power of 5 to 200W.

[0047] The height of the ultrasonic reactor material inlet 1 is the same as the height of the five ultrasonic transducers 6.

[0048] The ultrasonic transducer 6 and the reaction container 3 vibrate as a whole.

[0049] By setting up a reaction container 3, which is a regular hexagon, multiple ultrasonic transducers 6 are evenly arranged on the outer wall of the reaction container 3. The ultrasonic transducers 6 are connected in series and connected to the ultrasonic generator 7. During use, the radiation area can be effectively increased, the sound field distribution in the reactor chamber is stable and uniform, the cavitation activity is uniformly distributed, the power consumption of a single transducer is low, which can reduce decoupling losses and improve energy utilization efficiency. The centrally symmetrical design of the ultrasonic transducers 6 can concentrate the intensity in the central area, reducing the erosion of the inner wall surface and the problem of local cavitation. The generated sound field and temperature field are unified, effectively enhancing the heat transfer between the solid wall and the fluid. The liquid surface temperature is a radiative pattern with high temperature in the middle and low temperature around the edges.

[0050] Compared with Embodiment 1, another embodiment of this utility model is as follows:

[0051] The end of the ultrasonic reactor material outlet 4 away from the reaction container 3 is detachably equipped with a connecting tee pipe 8, wherein the input end of the connecting tee pipe 8 is connected to the ultrasonic reactor material outlet 4, and the material input from the ultrasonic reactor material inlet 1 is discharged through the connecting tee pipe 8.

[0052] A sealing ring 13 is fixedly installed on the inner wall of the connecting tee pipe 8. The radial outer wall of the sealing ring 13 has through holes corresponding to the output end of the connecting tee pipe 8. The radial outer wall of the connecting tee pipe 8 has two output ports. The number of through holes on the outer wall of the sealing ring 13 is the same as the number of output ports, so as to facilitate the passage of materials.

[0053] A control cylinder 12 is rotatably mounted on the inner wall of the connecting tee pipe 8. The outer wall of the control cylinder 12 fits against the inner wall of the sealing ring 13. The sealing connection between the connecting tee pipe 8 and the control cylinder 12 is achieved by setting the sealing ring 13.

[0054] The radial outer wall of the control cylinder 12 is provided with a through hole for material to pass through. By rotating the control cylinder 12 until the through hole on the outside of the control cylinder 12 is aligned with one of the output ports, the material is controlled to be discharged through the through hole.

[0055] The output end of the connecting tee pipe 8 is fixedly and detachably mounted with a connecting plate 10. The inner wall of the connecting plate 10 is provided with internal threads. The bottom surface of the connecting plate 10 is detachably mounted with a connecting cylinder 9.

[0056] A storage cylinder 16 is flexibly installed on the inner wall of the connecting cylinder 9, and a through hole is provided on the outer wall of the storage cylinder 16 for material to pass through.

[0057] The filtration assembly also includes a filter cylinder 22, which is fixedly installed on the inner wall of the storage cylinder 16. The material enters the inner cavity of the storage cylinder 16 through the connecting plate 10, is filtered by the filter cylinder 22, and is finally discharged through the connecting cylinder 9.

[0058] A support platform is rotatably mounted on the inner wall of the storage cylinder 16. An installation shaft 20 is rotatably mounted on the upper end face of the support platform, wherein the axis of the installation shaft 20 coincides with the axis of the storage cylinder 16. An adsorption blade 19 is fixedly mounted on the radial outer wall of the installation shaft 20. The adsorption blade 19 is common activated carbon, which is used to adsorb impurities when the material is discharged.

[0059] The adsorption blades 19 are spirally distributed and there are multiple blades 19. The multiple adsorption blades 19 are evenly distributed in a ring along the axis of the mounting shaft 20. When the material is discharged, the material impacts the adsorption blades 19 and drives the adsorption blades 19 to rotate, thereby improving the contact efficiency with the material and thus improving the adsorption efficiency of impurities.

[0060] A support bracket 17 is fixedly installed on the inner wall of the storage cylinder 16, and a connecting shaft 18 is elastically installed in the middle of the support bracket 17. The outer wall of the connecting shaft 18 slides against the inner wall of the support bracket 17.

[0061] One axial end of the connecting shaft 18 passes through the bearing bracket 17 and is fixedly connected to the center of the bottom surface of the storage cylinder 16. A spring is provided on the outer wall of the connecting shaft 18, and the other end of the spring is in contact with the bottom surface of the bearing bracket 17.

[0062] After the material flows into the storage cylinder 16, the material impacts the adsorption blade 19, thereby generating downward pressure, at which point the spring is compressed.

[0063] A guide cylinder 21 is fixedly installed on the inner wall of the connecting plate 10. The inner wall of the guide cylinder 21 slides against the outer wall of the storage cylinder 16. By sliding the guide cylinder 21 to the storage cylinder 16, the connection between the storage cylinder 16 and the connecting plate 10 can be maintained during the sliding of the storage cylinder 16, thereby facilitating the entry of materials into the inner cavity of the storage cylinder 16.

[0064] A guide vane 11 is rotatably installed on the inner wall of the output end of the connecting three-way pipe 8. The guide vane 11 is inclined and multiple vanes are evenly arranged in a ring. When the material passes through the connecting three-way pipe 8, the guide vane 11 rotates.

[0065] The bottom of the guide vane 11 is fixedly mounted with a control blade 15 via a connecting rod. When the guide vane 11 rotates, it drives the control blade 15 to rotate.

[0066] A support plate 14 is fixedly installed on the inner wall of the output end of the connecting three-way pipe 8. A fan-shaped groove is opened on the side wall of the support plate 14. The outer wall of the control blade 15 slides and fits against the upper end surface of the support plate 14. When the control blade 15 is rotated, the flow hole diameter of the support plate 14 is adjusted, thereby adjusting the water flow. When the material passes through, the impact force is changed. By adjusting the impact force in conjunction with the spring force, the storage cylinder 16 is controlled to shake up and down, thereby improving the filtration effect.
