Description

Technical Field

[0001] This invention relates to the field of ozone gas technology, specifically to an ozone gas desorption and treatment device and method. Background Technology

[0002] Ozone is an allotrope of oxygen. At room temperature and pressure, it appears pale blue and has a distinctive, pungent odor. At low concentrations, it smells like grass, while at high concentrations it produces a pungent odor. Ozone is a strong oxidizing agent and chemically reactive, reacting with a wide range of organic and inorganic substances. This characteristic makes it widely used in disinfection, water purification, and air purification. For example, it is used for environmental disinfection in medical settings, for degrading pollutants in wastewater treatment, and for extending shelf life in food processing. It is also an important component of the atmospheric ozone layer. Located in the stratosphere, the ozone layer absorbs harmful ultraviolet radiation from the sun, protecting life on Earth from radiation damage. However, high concentrations of ozone near the ground can harm human health, irritating the respiratory mucosa and causing symptoms such as coughing and sore throat. Long-term exposure may also damage lung function and inhibit plant growth. Therefore, when using ozone artificially, its concentration must be strictly controlled and properly analyzed. In environmental monitoring, ozone concentration is also one of the important indicators for measuring air quality.

[0003] In the current technical field, ozone desorption processes rely on manual segmented operations. During the standard solution preparation stage, operational errors during manual weighing of solid reagents and inaccurate control of liquid addition often affect the stability of subsequent detection benchmarks. Existing detection solution preparation methods suffer from large fluctuations in accuracy, insufficient stability, high operational risks, and low efficiency. During the operation, the solution is exposed to the air for a long time, and light and oxygen accelerate reagent decomposition, resulting in degradation after preparation. In addition, the manual operation process is loosely connected, often taking several hours from solution preparation to completion of detection, resulting in low detection efficiency. Furthermore, the manual handling of substances such as concentrated sulfuric acid and ozone lacks effective protection, posing significant health and safety risks. Although some semi-automatic equipment has achieved automation of single links, there is a lack of coordination and linkage mechanisms between links, still requiring manual intermediate transfer and parameter adjustment, which cannot form a complete closed-loop detection system and is difficult to meet the actual needs of batch testing and efficient quality control.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The first rotating module drives the fixed component above it to rotate. The telescopic module in the fixed component extends and retracts to drive the clamping module, moving the container to the bottom of the solid feeding device, the filling head, and the stirring device. The solid feeding device quantitatively feeds its pre-stored sodium indigo disulfonate solid into the container below through its outlet. The liquid storage system supplies its internally stored deionized water to the left filling head and quantitatively adds it into the container. The first electric telescopic rod drives the support frame to move downward so that the stirring rod inside the stirring device can be inserted into the back of the container. The motor inside the stirring device drives the stirring rod to stir inside the container. The liquid storage system supplies its internally stored concentrated sulfuric acid to the right filling head, and from the right... After concentrated sulfuric acid is quantitatively added into the container by the side filling head, during the addition process, the micro motors on the left and right sides drive the corresponding drive rods to move circumferentially clockwise or counterclockwise. The drive rods on the left and right sides drive the connecting rods at the other end to move synchronously. With the cooperation of the connecting rods on the left and right sides, the support seat is driven to move back and forth along the outside of the guide rail frame. With the cooperation of the clamping module, the support seat drives the container to vibrate the liquid inside, thereby uniformly adding concentrated sulfuric acid. The first rotating module drives the fixed part above it to rotate the container again to the bottom of the stirring device. With the cooperation of the first electric telescopic rod, the stirring device is inserted into the container again and stirred until the reaction is completed and a standard solution of sodium indigo disulfonate is formed.

[0020] 2. The fourth electric telescopic rod drives the rotating seat to rotate to the right. The rotating seat drives the front and rear rollers to move upward. The front and rear rollers move to the right along the inner cavity of the corresponding sliding groove, and with the cooperation of the rollers and the sliding groove, drive the lifting frame to move upward. The two side fixing modules extend to fix the bottom of the outer wall of the container. The fourth electric telescopic rod drives the rotating seat to rotate in the opposite direction, and drives the rollers to move downward, thereby causing the lifting frame to move downward along the inner cavity of the slot seat, so as to move the container through the inner cavity of the base shell slot to the bottom of the base shell. The first motor drives the base plate with the cooperation of the lead screw assembly. The base plate moves to the right along the base of the limiting assembly. The device moves to the lower inlet of the gas extraction and injection system, and with the cooperation of the internal structure of the moving part, the container above the lifting frame aligns with the lower inlet of the gas extraction and injection system. The operator then aligns the sampling bottle containing the gas to be tested with the inlet located on the outside of the top shell of the gas extraction and injection system. The gas extraction and injection system extracts the gas to be tested from the sampling bottle and discharges it into the inner cavity of the container above the lifting frame through its own inlet, allowing the gas to fully react with the sodium indigo disulfonate solution. After the gas filling is completed, the internal structure of the moving part resets, and the device continues to move the container to the lower part of the sample preparation mechanism.

[0021] 3. After the empty cuvette is placed inside the micro-clamping module and clamped and fixed by the transport robotic arm, the fifth electric telescopic rod drives the moving seat to move downward along the outside of the slide rail frame, so that the moving seat drives the clamping component to descend to the specified height position outside the container. The clamping component pours the sample solution inside the container into the liquid dropping system through the funnel. The liquid dropping system quantitatively adds a specified amount of sample solution to the empty cuvette inside the micro-clamping module. The transport robotic arm transfers the cuvette inside the micro-clamping module to the spectrophotometer. The spectrophotometer detects the absorbance of the absorbing liquid and calculates the ozone concentration inside the sample gas by referring to the standard curve.

[0022] In summary, this invention enables automated and coordinated control of the entire ozone detection process, improves reaction sufficiency, avoids detection deviations caused by incomplete local reactions, and ensures uniform sample dosage during sample preparation. This effectively avoids health hazards to operators from chemical reagent volatilization and ozone leakage, meeting the multiple requirements for detection accuracy, efficiency, and safety in industrial and laboratory settings.

The peristaltic pump head uses corrosion-resistant silicone tubing, which is compatible with sodium indigo disulfonate reaction solution. The micro clamping module 68 is installed on the outer surface of the second vertical frame 66 and located below the liquid dispensing system 67's outlet. The micro clamping module 68 is electrically connected to controller 3 and uses small electric fingers. The inner side of the clamping claws is attached with PTFE anti-slip pads, specifically for fixing standard cuvettes. The funnel 69 is installed at the top of the liquid inlet of the liquid dispensing system 67 and is made of high borosilicate glass.

[0035] The specific tasks are as follows:

[0036] Step 1: Prepare a standard solution of sodium indigo disulfonate:

[0037] S1: After the operator starts the controller 3, the controller automatically activates the telescopic module 413 and the clamping module 417 according to the preset program. The telescopic module 413 extends forward, driving the clamping module 417 to the inside of the left sealing door of the top shell 2. The operator opens the left sealing door and puts the clean reaction container into the clamping mouth of the clamping module 417. The clamping module 417 tightens to complete the fixation, and then the operator closes the sealing door.

[0038] S2: Controller 3 synchronously starts the first rotating module 42, the second electric telescopic rod 47 and the solid feeding device 48. The first rotating module 42 drives the fixed part on its top to rotate. At the same time, the telescopic module 413 adjusts the position by telescopically moving the container to directly below the discharge port of the solid feeding device 48. The second electric telescopic rod 47 extends downward so that the discharge port of the solid feeding device 48 is close to the top opening of the container. The solid feeding device 48 quantitatively feeds the pre-stored sodium indigo disulfonate solid powder into the container according to the preset dosage.

[0039] S3: After feeding is completed, the first rotating module 42 drives the container to rotate again, and in conjunction with the telescopic module 413, moves the container to below the left filling head 410. The third electric telescopic rod 49 on the left extends downward, so that the left filling head 410 is close to the container opening. The liquid storage system 411 delivers a preset volume of deionized water to the filling head. After the water is added, the container is transferred to below the stirring device 45. The first electric telescopic rod 46 pushes the support frame 44 downward, inserting the stirring rod of the stirring device 45 into the liquid in the container. After the stirring device 45 is started, it drives the stirring rod to rotate at high speed, so that the sodium indigo disulfonate solid powder is completely dissolved in the deionized water. After the dissolution is completed, the first electric telescopic rod 46 retracts, and the stirring rod is pulled out of the container.

[0040] S4: With the cooperation of the first rotating module 42 and the telescopic module 413, the container moves to the bottom of the right-side filling head 410. The right-side third electric telescopic rod 49 drives the right-side filling head 410 to come close to the container. The liquid storage system 411 injects a preset dose of concentrated sulfuric acid into the container through the right-side filling head 410. During the filling process, the micro motors 419 on both sides drive the drive rod 420 to rotate clockwise or counterclockwise. The drive rod 420 pulls the connecting rod 418, which in turn drives the support seat 416 to slide back and forth along the guide rail frame 415. The support seat 416 is linked with the clamping module 417, causing the container to shake back and forth, so that the concentrated sulfuric acid and the solution are quickly mixed.

[0041] S5: After the shaking ends, the container is moved back to the bottom of the stirring device 45. The first electric telescopic rod 46 pushes the stirring rod into the solution, and the stirring device 45 is started again to stir thoroughly until the solution forms a uniform and stable sodium indigo disulfonate standard solution.

[0042] Step 2: Reaction of ozone gas with standard solution:

[0043] S1: After the sodium indigo disulfonate standard solution is prepared, the first rotating module 42 drives the fixed component to turn forward, and the telescopic module 413 extends to move the container to the top of the groove on the base housing 41. The fourth electric telescopic rod 425 retracts, causing the rotating seat 426 to rotate to the right. The roller 427 on the rotating seat 426 rolls upward along the sliding groove 431, pushing the lifting frame 429 to move upward along the slot seat 428, passing through the groove of the base housing 41 and reaching the bottom of the container. The two fixed modules 430 on the lifting frame 429 extend and clamp the bottom of the container from the outside. The fourth electric telescopic rod 425 extends and resets, causing the lifting frame 429 and the container to move downward, passing through the groove and entering the transfer position below the base housing 41.

[0044] S2: The first motor 423 starts, driving the screw of the lead screw assembly 422 to rotate. The lead screw nut drives the base plate 424 and the upper container to move to the right along the limit assembly base 41 until the container opening moves to the lower filling port position of the gas extraction and injection system 5. The fourth electric telescopic rod 425 shortens again, driving the lifting frame 429 and the container to move upward and connect with the lower filling port of the extraction and injection system 5. The staff connects the sampling bottle containing the ozone gas to be tested to the air inlet exposed outside the top shell 2 of the gas extraction and injection system 5. After the extraction and injection system 5 starts, it extracts the detection gas in the sampling bottle and injects it into the sodium indigo disulfonate standard solution in the container at a uniform speed through the filling port. The ozone reacts fully with the solution, and the blue color of the solution gradually fades. After the reaction is completed, the moving parts are reset, driving the container to continue to move to the right and stop directly below the detection sample preparation mechanism 6, waiting for the subsequent sample transfer.

[0045] Step 3: Sample solution detection and concentration calculation:

[0046] S1: Controller 3 starts the transport robot arm 8, and its gripping end moves to the inside of the right sealing door of the top housing 2. The operator opens the right sealing door and puts the clean and dried empty cuvette into the gripping end of the transport robot arm 8. After the transport robot arm 8 clamps the cuvette, the operator closes the sealing door. The transport robot arm 8 sends the cuvette into the clamping mouth of the micro clamping module 68. The micro clamping module 68 tightens and fixes the cuvette, and the transport robot arm 8 then releases and resets.

[0047] S2: The fifth electric telescopic rod 65 extends, driving the movable seat 44 to move downward along the slide rail frame 63, so that the clamping component on the front side of the movable seat 44 is lowered to a suitable height outside the container. The clamping component clamps the outer wall of the container, and the fixing module 430 on the movable component retracts to release the workpiece. The fifth electric telescopic rod 65 shortens, raising the container to the specified height. The second rotating module 61 drives the first vertical frame 62 to rotate 90 degrees, so that the container opening faces the funnel 69 on the right. The clamping component tilts the container, and the solution after reaction inside the container flows into the storage chamber of the liquid dropping system 67 through the funnel 69. The liquid dropping system 67 accurately drops the solution into the cuvette fixed by the micro clamping module 68 below according to the preset dosage, completing the preparation of the test sample.

[0048] S3: The robotic arm 8 restarts, removes the cuvette containing the sample solution from the micro clamping module 68, transfers it to the detection chamber of the spectrophotometer 7 and closes the chamber door. The spectrophotometer 7 starts automatically and detects the absorbance of the solution at a wavelength of 610nm. The detection data is transmitted to the controller 3 in real time. The controller 3 automatically calculates the ozone concentration in the gas to be detected using the built-in ozone concentration and absorbance standard curves. The entire detection process is then completed.

The first electric telescopic rod (46) pushes the stirring rod into the solution, and the stirring device (45) is started again to stir thoroughly until the solution forms a uniform and stable sodium indigo disulfonate standard solution. Step 2: Reaction of ozone gas with standard solution: S21: After the sodium indigo disulfonate standard solution is prepared, the first rotating module (42) drives the fixed part to turn to the front, the telescopic module (413) extends to move the container to the top of the groove of the base shell (41), the fourth electric telescopic rod (425) retracts to drive the rotating seat (426) to rotate to the right, the roller (427) on the rotating seat (426) rolls upward along the sliding groove (431), pushing the lifting frame (429) to move upward along the slot seat (428), and after passing through the groove of the base shell (41), it reaches the bottom of the container. The two fixed modules (430) on the lifting frame (429) extend to clamp the bottom of the container from the outside. The fourth electric telescopic rod (425) extends and resets, driving the lifting frame (429) and the container to move downward, passing through the groove and entering the transfer position below the base shell (41). S22: The first motor (423) starts, driving the screw of the lead screw assembly (422) to rotate. The lead screw nut drives the base plate (424) and the upper container to move to the right along the limit assembly base (421) until the container opening moves to the lower filling port position of the gas extraction and injection system (5). The fourth electric telescopic rod (425) shortens again, driving the lifting frame (429) and the container to move upward and connect with the lower filling port of the extraction and injection system (5). The staff connects the sampling bottle containing the ozone gas to be tested to the air inlet of the gas extraction and injection system (5) exposed outside the top shell (2). After the extraction and injection system (5) starts, it extracts the detection gas in the sampling bottle and injects it into the sodium indigo disulfonate standard solution in the container at a uniform speed through the filling port. The ozone reacts fully with the solution, and the blue color of the solution gradually fades. After the reaction is completed, the moving parts are reset, driving the container to continue to move to the right and stop directly below the detection sample preparation mechanism (6) to wait for the subsequent sample transfer. Step 3: Sample solution detection and concentration calculation: S31: The controller (3) starts the transport robot arm (8), and its gripping end moves to the inside of the right sealing door of the top shell (2). The operator opens the right sealing door and puts the clean and dried empty cuvette into the gripping end of the transport robot arm (8). After the transport robot arm (8) clamps the cuvette, the operator closes the sealing door. The transport robot arm (8) sends the cuvette into the clamping mouth of the micro clamping module (68). The micro clamping module (68) tightens and fixes the cuvette. The transport robot arm (8) then releases and resets. S32: The fifth electric telescopic rod (65) extends, driving the moving seat (64) to move downward along the slide rail frame (63), so that the clamping component on the front side of the moving seat (64) is lowered to a suitable height outside the container. The clamping component clamps the outer wall of the container. The fixing module (430) on the moving component retracts to release the workpiece. The fifth electric telescopic rod (65) shortens, raising the container to a specified height. The second rotating module (61) drives the first vertical frame (62) to rotate (90) degrees, so that the container opening faces the funnel (69) on the right. The clamping component tilts the container. The solution after reaction inside the container flows into the storage chamber of the liquid dripping system (67) through the funnel (69). The liquid dripping system (67) accurately drips the solution into the cuvette fixed by the micro clamping module (68) below according to the preset dose, completing the preparation of the test sample. S33: The handling robotic arm (8) starts again, takes the cuvette containing the sample solution from the micro clamping module (68), transfers it to the detection chamber of the spectrophotometer (7) and closes the chamber door. The spectrophotometer (7) starts automatically and detects the absorbance of the solution at a wavelength of 610nm. The detection data is transmitted to the controller (3) in real time. The controller (3) automatically calculates the ozone concentration in the gas to be detected through the built-in ozone concentration and absorbance standard curve. The entire detection process is completed.
