Description

Technical Field

[0001] This application relates to the field of wastewater treatment equipment technology, specifically providing an automated ultraviolet sterilization device for a wastewater treatment line. Background Technology

[0002] Ultraviolet sterilization equipment typically uses multiple sets of ultraviolet sterilization lamps to achieve water sterilization. It is the mainstream automated equipment for end-of-pipe disinfection in wastewater treatment plants. With low-pressure / low-pressure high-intensity amalgam ultraviolet lamps as the core, it achieves sterilization by destroying the DNA / RNA of microorganisms with 254nm UV-C ultraviolet light. It does not require chemical agents and causes no secondary pollution; it is a key piece of equipment for wastewater treatment and remediation.

[0003] In the prior art, the invention patent with publication number CN112744892A discloses a self-cleaning open channel ultraviolet sterilization device for sewage treatment. The device uses water flow to drive the cleaning rod of the cleaning component to rotate, and uses the scraper to rub against the outer wall of the quartz sleeve to remove scale. At the same time, the lamp holder spacing is fixed.

[0004] However, this technology has obvious drawbacks compared to the present application. First, the mechanical scraping method for descaling is prone to damaging the quartz sleeve outside the ultraviolet lamp tube, reducing the ultraviolet transmission efficiency and affecting the sterilization effect. Second, the lamp holder spacing cannot be dynamically adjusted according to the sewage level. When the liquid level is too high, the narrow flow channel can easily cause the water level to rise, exacerbating the head pressure in the open channel. When the liquid level is normal, it is also impossible to ensure the rationality of the ultraviolet irradiation density, resulting in poor adaptability. In addition, the cleaning structure of this equipment relies on water flow drive. When the sewage flow is small, the cleaning effect is greatly reduced, and it is impossible to effectively remove scale according to the actual scaling condition of the lamp tube. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this application provides an automated ultraviolet sterilization device for wastewater treatment lines. This device effectively solves the technical problems of existing open-channel ultraviolet sterilization equipment, which suffers from the following issues: mechanical scraping for descaling easily damages the quartz sleeves of lamps, reduces ultraviolet transmission efficiency, has a fixed lamp holder spacing that cannot be dynamically adjusted with the wastewater level, easily causes water level rise and increases head pressure, and the descaling method cannot be adjusted in real time according to the actual scaling situation of the lamps, thus affecting the sterilization effect and equipment stability.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] This application discloses an automated ultraviolet sterilization device for a wastewater treatment line, including an adjustable main frame. The adjustable main frame is provided with an X-direction crossbeam, an inverted concave lamp holder, an ultraviolet sterilization lamp tube, and a suspended bracket. The inverted concave lamp holder is movably mounted on the X-direction crossbeam. The ultraviolet sterilization lamp tube is mounted below the inverted concave lamp holder. The suspended bracket is connected to the top of the adjustable main frame. The device also includes a responsive adjustment mechanism and a responsive descaling mechanism.

[0008] The responsive adjustment mechanism is installed on the top of the inverted concave lamp holder and the suspended bracket, and is used to adjust the spacing of each inverted concave lamp holder and ultraviolet sterilization lamp tube according to the height of the sewage liquid level.

[0009] The responsive descaling mechanism is mounted on the suspended bracket and the inverted concave lamp holder. It is used to monitor the light intensity of the ultraviolet sterilization lamp tube and spray high-pressure airflow onto the outer circumferential surface of the ultraviolet sterilization lamp tube to remove dirt when the intensity weakens.

[0010] Preferably, the responsive adjustment mechanism includes a sensing and monitoring device, a linear drive component, and a scissor-type articulated telescopic frame;

[0011] The sensing and monitoring device is installed on the outside of the X-direction crossbeam to monitor the level of sewage.

[0012] The linear drive component is fixedly installed on the top of one side of the ceiling bracket, and its linear motion output end is connected to the side wall of an inverted concave lamp holder, which is used to drive the inverted concave lamp holder to translate along the X direction.

[0013] The scissor-type articulated telescopic frame is hinged to the top of each inverted concave lamp holder, and is used in conjunction with the linear drive component to drive each inverted concave lamp holder to achieve equidistant spacing adjustment.

[0014] Preferably, the responsive descaling mechanism includes a support platform, a booster pump, a main gas supply pipe, a branch gas supply pipe, a diversion solenoid valve, a gate-type branch pipe, an annular cavity ring, and a valved jet nozzle.

[0015] The support platform is fixedly installed on one side of the top of the suspended bracket;

[0016] The booster air pump is installed on the top surface of the support platform;

[0017] The main gas supply pipe is connected to the gas supply end of the booster pump via a main solenoid valve;

[0018] The gas supply branch pipe is connected to the gas supply main pipe, and the gas supply branch pipe is provided with a diversion section that corresponds to the number and position of the inverted concave lamp holders;

[0019] The diversion solenoid valves are located at each diversion point of the gas transmission branch pipe;

[0020] The portal branch pipe is connected to the diversion solenoid valve;

[0021] The annular cavity is connected to both ends of the bottom of the portal branch pipe and is coaxially arranged at the end of the ultraviolet sterilization lamp tube.

[0022] In summary, the technical solution provided in this application has at least one of the following advantages compared with the prior art:

[0023] This automated ultraviolet sterilization equipment for wastewater treatment line solves the problems of existing ultraviolet sterilization equipment, such as the inability of lamp spacing to adapt to the liquid level and the easy damage to the quartz sleeve during lamp descaling, by setting up a responsive adjustment mechanism and a responsive descaling mechanism. The equipment can automatically adjust the lamp spacing according to the wastewater level and perform non-contact descaling, ensuring the sterilization effect while extending the lamp life.

[0024] The responsive adjustment mechanism uses an ultrasonic level sensor to acquire liquid level signals in real time. In conjunction with the linkage of a servo telescopic cylinder and a scissor-type articulated telescopic frame, it can achieve precise equidistant adjustment of the lamp holder spacing. When the liquid level is too high, it widens the flow channel to prevent the water level from rising. When the liquid level is normal, it ensures the irradiation density and adapts to the dynamic changes in sewage flow and liquid level.

[0025] The responsive descaling mechanism uses high-pressure airflow for non-contact descaling, combined with an annular cavity ring and an inclined valved jet nozzle to achieve all-round flushing of the outer circumference of the lamp tube, removing scale more thoroughly. It also has a built-in one-way valve to prevent sewage backflow, avoid air circuit blockage and corrosion, and ensure the effectiveness of the descaling action and the operational stability of the air circuit system.

[0026] The diversion solenoid valve can independently open and close the gas path corresponding to a single lamp, and can perform targeted descaling on lamps with scale buildup without having to start the entire descaling mechanism, thus reducing the energy consumption of the equipment and making the equipment more energy-efficient, suitable for the continuous operation of sewage treatment lines.

[0041] The present application will be further described below with reference to embodiments.

[0042] As a first embodiment of this application:

[0043] Reference Appendix Figures 1 to 5 As shown, an automated ultraviolet sterilization device for a sewage treatment line includes an adjustable main frame 1, which consists of four adjustable main frames 1. Each adjustable main frame 1 is composed of a fixed rod and a movable rod inserted into the fixed rod. The fixed rod and the movable rod are connected by an adjusting bolt with an external thread to form a damping limit structure. Loosening the adjusting bolt can adjust the extension length of the movable rod along the axial direction of the fixed rod, thereby adapting to the sewage level of different open channels and ensuring that the ultraviolet sterilization lamp is always in the appropriate irradiation position, thus improving the adaptability of the equipment to different working conditions.

[0044] An X-direction crossbeam 11 is fixedly connected between the top inner sides of two adjustable main frame bodies 1 located on the same side. Several inverted concave lamp holders 12 are installed on the two X-direction crossbeams 11. One inverted concave lamp holder 12 in the middle is fixedly embedded between the two X-direction crossbeams 11, while the remaining inverted concave lamp holders 12 are movably installed on the X-direction crossbeams 11. All the inverted concave lamp holders 12 are evenly distributed. Several evenly distributed ultraviolet sterilization lamp tubes 13 are fixedly installed below each inverted concave lamp holder 12. The tops of the four adjustable main frame bodies 1 are fixedly connected to a suspended ceiling bracket 14. The suspended ceiling bracket 14 provides a stable installation foundation for various functional components of the equipment and improves the structural rigidity of the overall frame.

[0045] Further implementation includes a responsive adjustment mechanism 2, which is installed on the top of the inverted concave lamp holder 12 and the suspended bracket 14. This mechanism is used to adjust the spacing between the inverted concave lamp holders 12 and the ultraviolet sterilization lamps 13 according to the sewage level. The responsive adjustment mechanism 2 includes a sensing and monitoring device 21, a linear drive component 22, a scissor-type articulated telescopic frame 23, and a limiting sliding structure. The sensing and monitoring device 21 is an ultrasonic level sensor installed on the outside of the X-direction crossbeam 11 in the direction of water flow. It acquires real-time sewage level information by emitting and receiving reflected ultrasonic signals, and then converts this information into an electrical signal transmitted to the main controller of the equipment, providing an effective signal basis for spacing adjustment. The linear drive component 22 is a servo telescopic cylinder, fixedly installed on the top side of the suspended bracket 14. Its linear motion output end is fixedly connected to the side wall of one of the inverted concave lamp holders 12 near that end. The extension and retraction of the stopper rod is controlled by the main controller based on the liquid level signal, realizing linear drive of the connected inverted concave lamp holders; the scissor-type articulated telescopic frame 23 is hinged to the top of each inverted concave lamp holder 12, and has several first hinge parts and second hinge parts. Each first hinge part is distributed in a straight line along the middle of the scissor-type articulated telescopic frame 23 and is rotatably connected to the top of each inverted concave lamp holder 12. Each second hinge part is distributed on both sides of the straight line in the middle, and each second hinge part is hinged to each other and correspondingly hinged to the connecting rod of the scissor-type articulated telescopic frame 23. When the linear drive component 22 drives a single inverted concave lamp holder 12 to move, the scissor-type articulated telescopic frame realizes synchronous expansion or folding through the hinge linkage between the connecting rods, thereby driving the remaining moving inverted concave lamp holders to move synchronously at equal distances, ensuring that the spacing between each ultraviolet sterilization lamp tube is always uniform, ensuring that the sewage can receive uniform ultraviolet irradiation when it flows through, and avoiding insufficient local irradiation dose.

[0046] Furthermore, a limiting sliding structure is provided between the remaining inverted concave lamp holders 12 (excluding the central inverted concave lamp holder 12) and the X-direction crossbeam 11. This structure includes a guide pulley 24 and a guide wheel groove 25. The guide pulley 24 is rotatably connected to the bottom of both ends of the top of the inverted concave lamp holder 12. The guide wheel groove 25 is opened at the top of the X-direction crossbeam 11. The guide pulley 24 is slidably embedded in the guide wheel groove 25. This structure converts the sliding friction between the inverted concave lamp holder and the X-direction crossbeam into rolling friction, reducing motion resistance. At the same time, the guide wheel groove limits the sliding trajectory of the guide pulley, preventing swaying or jamming when the inverted concave lamp holder moves horizontally, and ensuring the smoothness and stability of the spacing adjustment.

[0047] As a second embodiment of this application:

[0048] Reference Appendix Figure 1 , Figures 6 to 9 As shown, the above-mentioned automated ultraviolet sterilization equipment for a wastewater treatment line also includes a responsive descaling mechanism 3. The responsive descaling mechanism 3 is mounted on the suspended bracket 14 and the inverted concave lamp holder 12. It is used to monitor the light intensity of the ultraviolet sterilization lamp tube 13 and spray high-pressure airflow onto the outer circumferential surface of the ultraviolet sterilization lamp tube 13 to remove dirt when the intensity weakens. The descaling is carried out by a non-contact high-pressure airflow impact method, which avoids the damage to the quartz sleeve outside the ultraviolet sterilization lamp tube caused by the traditional mechanical scraping method, ensures the transmission efficiency of ultraviolet light, reduces the wear and tear of components, and extends the overall service life of the equipment.

[0049] Further implemented, the responsive descaling mechanism 3 includes a support platform 31, a booster pump 32, a main air supply pipe 33, a branch air supply pipe 34, a diversion solenoid valve 35, a gate-type branch pipe 36, an annular cavity ring 37, a valved jet nozzle 371, and a light intensity detection element 301. The support platform 31 is fixedly mounted on one side of the top of the suspended bracket 14. The booster pump 32 is installed on the top surface of the support platform 31. The booster pump is equipped with a controller, which can receive external signals and realize automatic start and stop, providing a stable high-pressure airflow for the descaling operation. Power; The main gas supply pipe 33 is connected to the gas supply end of the booster pump 32 through the main solenoid valve. The main solenoid valve controls the overall on / off of the gas path. The gas supply branch pipe 34 is connected to the main gas supply pipe 33. The gas supply branch pipe 34 is provided with a diversion section corresponding to the number and position of the inverted concave lamp holders 12. The diversion solenoid valve 35 is provided at each diversion section of the gas supply branch pipe 34, which can realize the independent on / off of the gas path corresponding to a single inverted concave lamp holder. It can perform targeted descaling of the scaled ultraviolet sterilization lamp tubes and reduce unnecessary energy consumption.

[0050] The portal branch pipe 36 is connected to the diversion solenoid valve 35 and is horizontally mounted and fixed on the ceiling bracket 14. The portal branch pipe can move synchronously with the translation of the inverted concave lamp holder to ensure continuous air circuit connection and avoid air circuit breakage or leakage caused by lamp holder movement.

[0051] The annular cavity ring 37 is connected to the bottom two ends of the portal branch pipe 36 and is coaxially arranged at the end of the ultraviolet sterilization lamp tube 13. The annular cavity ring is specially set at the non-light-emitting end of the ultraviolet sterilization lamp tube to avoid blocking the ultraviolet irradiation area and ensure that the sterilization effect is not affected by the descaling structure. Each ultraviolet sterilization lamp tube 13 has an annular cavity ring 37 at both ends. The valve-equipped jet nozzle 371 is distributed in a ring on the side of the annular cavity ring 37 facing the ultraviolet sterilization lamp tube 13 and is connected to the annular cavity ring 37. The valve-equipped jet nozzle 371 is inclined towards the outer circumference of the ultraviolet sterilization lamp tube 13. The high-pressure airflow sprayed at an angle forms a directional high-speed impact flow in the water, and at the same time drives the surrounding water flow to form a swirling flow, which forms an all-round flushing of the outer wall of the ultraviolet sterilization lamp tube. The impact force and cavitation effect of the water flow are used to peel off the scale and biofilm.

[0052] The built-in one-way valve of the valved jet nozzle 371 can effectively prevent sewage backflow into the air path, avoid blockage and corrosion of the air path, and ensure the operational stability of the air path system; the light intensity detection component 301 is an ultraviolet intensity sensor, which is installed on the bottom surface of the top of each inverted concave lamp holder 12, with its detection end facing the ultraviolet sterilization lamp tube 13 below vertically.

[0053] This detection device can monitor the effective irradiation intensity of the ultraviolet sterilization lamp in real time. When the detected intensity is lower than the preset threshold, it is determined that the lamp tube is scaled or the lamp tube is attenuating. The signal is then transmitted to the controller of the booster air pump to trigger the descaling action. When the irradiation intensity recovers to above the preset threshold, the controller controls the booster air pump to stop and closes all solenoid valves, terminating the descaling action.

[0054] As a supplement, the aforementioned main gas pipe 33, branch gas pipe 34, portal branch pipe 36, annular cavity ring 37, and valve-equipped nozzle 371 are all made of corrosion-resistant metal materials, specifically 316L stainless steel, to avoid corrosion and leakage.

[0055] The complete working and usage principle of the above embodiments is as follows:

[0056] During equipment installation, first adjust the extension length of the movable rod by loosening the adjusting bolts of the adjustable main frame 1 according to the actual sewage level in the open channel, so that the ultraviolet sterilization lamp tube 13 is in the appropriate irradiation position, and then tighten the bolts to complete the limit fixation.

[0057] After the equipment is in operation, the sensing and monitoring device 21 detects the sewage level in real time and transmits the signal to the main controller. The controller controls the linear drive component 22 to move according to the liquid level change, which drives the individual inverted concave lamp holder 12 to move. Through the hinge linkage of the scissor-type hinge telescopic frame 23, the other inverted concave lamp holders 12 are moved synchronously and equidistantly to adjust the lamp spacing. At the same time, the light intensity detection component 301 continuously monitors the irradiation intensity of the ultraviolet sterilization lamp tube 13. When the intensity is lower than the preset threshold, the signal is transmitted to the controller of the booster air pump 32, triggering the booster air pump 32 to start. The main solenoid valve and the corresponding diversion solenoid valve 35 are opened. The high-pressure airflow is delivered to the annular cavity ring 37 through the main air supply pipe 33, the branch air supply pipe 34, and the gate-type branch pipe 36. It is then sprayed obliquely from the valve-equipped jet nozzle 371 onto the outer circumference of the lamp tube. The scale layer is peeled off by the water flow impact and cavitation effect. After the intensity recovers, the air pump stops, the solenoid valve closes, and the descaling action ends. The limiting sliding structure provides guidance and limitation for the lamp holder's translation throughout the entire process. The air circuit components are made of 316L stainless steel to prevent corrosion and leakage and ensure the stability of the air circuit.
