Description

Technical Field

[0001] The utility model belongs to the technical field of optical fiber manufacturing equipment, and in particular relates to a deuterium gas processing intelligent circulation scheduling system. Background Art

[0002] During the optical fiber drawing process, disordered silicon-oxygen bond (Si-O) free radicals are generated. These radicals easily react with hydrogen atoms (H) to form silanol (Si-OH) groups, which in turn increases the water peak at 1385nm, affecting the fiber's transmission performance. To address this issue, all full-wave optical fibers undergo deuterium treatment after drawing. Deuterium (D or 2H) replaces ordinary hydrogen, reducing the generation of silanol (Si-OH) groups and enhancing the fiber's resistance to hydrogen aging, allowing it to withstand long-term corrosion in hydrogen-containing environments.

[0003] Deuterium, an isotope of hydrogen with the chemical symbol D or 2H, has an abundance of only 0.015% on Earth. This means that while deuterium is present in seawater and ordinary water, its content in ordinary hydrogen is very low, and most of it exists in the form of heavy water (D2O), also known as deuterium oxide. As a scarce resource, deuterium is expensive, which directly increases the production cost of optical fiber. Therefore, how to effectively reduce deuterium consumption while ensuring optical fiber quality has become a pressing issue in the optical fiber manufacturing industry. Utility Model Content

[0004] In response to the above-mentioned problems in the prior art, the present invention aims to provide an intelligent circulation scheduling system for deuterium gas processing, which can achieve efficient recycling of deuterium gas and solve the problem of high optical fiber manufacturing costs.

[0005] In order to achieve the above-mentioned purpose of the utility model, the technical solution adopted by the utility model is as follows: a deuterium gas treatment intelligent circulation scheduling system is provided, which includes a control system, an air intake pipe and an exhaust pipe, one end of the air intake pipe is connected to a deuterium gas source, and the other end is closed; a plurality of deuterium gas treatment tanks are arranged in parallel between the air intake pipe and the exhaust pipe, and a deuterium gas concentration sensor and an air pressure sensor are arranged inside each of the deuterium gas treatment tanks, the top of each deuterium gas treatment tank is connected to the air intake pipe through an air intake pipe with a first solenoid valve, the bottom of the deuterium gas treatment tank is connected to the exhaust pipe through an air outlet pipe with a second solenoid valve, a third solenoid valve is provided at the outlet of the exhaust pipe, and one side of the deuterium gas treatment tank is connected to a vacuum pump through a vacuum tube with a fourth solenoid valve;

[0006] The deuterium gas concentration sensor, the air pressure sensor, the first solenoid valve, the second solenoid valve, the third solenoid valve, the fourth solenoid valve and the vacuum pump are all electrically connected to the control system.

[0007] The basic principle of the intelligent circulation scheduling system for deuterium treatment in the utility model is as follows: after the deuterium treatment tank A in the intelligent circulation scheduling system for deuterium treatment completes the deuterium treatment of the optical fiber, the first solenoid valve, the second solenoid valve, the third solenoid valve and the fourth solenoid valve arranged on the deuterium treatment tank A are all closed, and the deuterium treatment tank A enters a standby state; when the deuterium treatment tank B is required to perform deuterium treatment on the optical fiber, the fourth solenoid valve and the vacuum pump are opened through the control system to evacuate the deuterium treatment tank B. When the evacuation of the deuterium treatment tank B is completed, the second solenoid valves on the deuterium treatment tank A and the deuterium treatment tank B are opened, and the deuterium treatment tank B is evacuated. The deuterium gas in the body A is transported to the deuterium gas treatment tank body B until the pressure is balanced, and then the first solenoid valve on the deuterium gas treatment tank body B is opened, and the air inlet pipe replenishes the deuterium gas to the deuterium gas treatment tank body B until the deuterium gas concentration and the air pressure in the deuterium gas treatment tank body B reach the preset value and then stops. The deuterium gas treatment tank body B performs deuterium treatment on the optical fiber; during the deuterium treatment process of the optical fiber, the remaining deuterium gas treatment tank bodies also adopt the above operation to circulate the deuterium gas in multiple deuterium gas treatment tank bodies, thereby realizing the recycling and intelligent scheduling of deuterium gas, significantly reducing the deuterium gas consumption in the optical fiber production process, thereby reducing the optical fiber production cost and enhancing the market competitiveness of the enterprise.

[0008] Furthermore, the air intake pipe is connected to a pressure-balancing pipe with a fifth solenoid valve, which is connected to an external air intake device. The external air pressure device delivers air to the deuterium treatment tank through the pressure-balancing pipe, thereby adjusting the deuterium concentration and pressure within the deuterium treatment tank.

[0009] Furthermore, the optical fiber deuterium treatment process consumes a very small amount of deuterium gas, and the air in the tank will not be 100% exhausted during vacuuming, which will cause the deuterium concentration to decrease. The deuterium concentration in each deuterium treatment tank is 2%, and the air pressure is 0.05 MPa, which can eliminate the hydrogen loss defect of the optical fiber.

[0010] Furthermore, the deuterium gas concentration in the deuterium gas source is 3%, and the vacuum pump evacuates at a pressure of 0.08 MPa, so that the deuterium gas treatment intelligent circulation scheduling system ensures that the deuterium gas concentration in the deuterium gas treatment tank is 2% during long-term operation.

[0011] Furthermore, the control system is electrically connected to a reaction time module and a touch display, and the touch display is used for the deuterium gas concentration, air pressure and reaction time of each deuterium gas treatment tank, so that the operator can intuitively understand the working status of each deuterium gas treatment tank; the touch display is also provided with a touch switch button, a touch emergency stop button and a touch start and stop button; the touch switch button is used to control the working status of the first solenoid valve, the second solenoid valve, the third solenoid valve, the fourth solenoid valve, the fifth solenoid valve and the vacuum pump; the touch emergency stop button is used to control the emergency stop of the deuterium gas treatment intelligent circulation scheduling system; the touch emergency stop button is used to turn off or start the deuterium gas treatment intelligent circulation scheduling system; the setting of the touch switch button, the touch emergency stop button and the touch start and stop button can facilitate the operator to manually control the entire deuterium gas treatment intelligent circulation scheduling system.

[0012] The beneficial effects of the present invention are as follows: the present invention provides an intelligent circulation scheduling system for deuterium gas processing, which controls multiple deuterium gas processing tanks so that deuterium gas is circulated in multiple deuterium gas processing tanks, thereby realizing the recycling and intelligent scheduling of deuterium gas, significantly reducing the deuterium gas consumption in the optical fiber production process, thereby reducing the optical fiber production cost and enhancing the market competitiveness of the enterprise.

For those skilled in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the appended claims, these changes are obvious, and all inventions and creations conceived using the present invention are protected.

[0016] like Figure 1As shown, the utility model provides an intelligent circulation scheduling system for deuterium gas treatment, which includes a control system, an air intake pipe 1 and an exhaust pipe 2, wherein one end of the air intake pipe 1 is connected to a deuterium gas source 3 and the other end is closed; the air intake pipe 1 and the exhaust pipe 2 are spaced apart in the vertical direction, and a plurality of deuterium gas treatment tanks 4 are arranged in parallel between the air intake pipe 1 and the exhaust pipe 2. Specifically, a deuterium gas concentration sensor and an air pressure sensor are provided inside each of the deuterium gas treatment tanks 4, the top of each deuterium gas treatment tank 4 is connected to the air intake pipe 1 through an air intake pipe 6 with a first solenoid valve 5, the bottom of the deuterium gas treatment tank 4 is connected to the exhaust pipe 2 through an air outlet pipe 8 with a second solenoid valve 7, a third solenoid valve 9 is provided at the outlet of the exhaust pipe 2, and one side of the deuterium gas treatment tank 4 is connected to a vacuum pump 12 through a vacuum tube 11 with a fourth solenoid valve 10.

[0017] The deuterium gas concentration sensor, the air pressure sensor, the first solenoid valve 5 , the second solenoid valve 7 , the third solenoid valve 9 , the fourth solenoid valve 10 and the vacuum pump 12 are all electrically connected to the control system.

[0018] The actual use process of the deuterium treatment intelligent circulation scheduling system is as follows: after the deuterium treatment tank A in the deuterium treatment intelligent circulation scheduling system completes the deuterium treatment of the optical fiber, the first solenoid valve 5, the second solenoid valve 7, the third solenoid valve 9 and the fourth solenoid valve 10 set on the deuterium treatment tank A are all closed, and the deuterium treatment tank A enters the standby state; when the deuterium treatment tank B is required to perform deuterium treatment on the optical fiber, the fourth solenoid valve 10 and the vacuum pump 12 are opened through the control system to evacuate the deuterium treatment tank B. When the deuterium treatment tank B is evacuated, the second solenoid valve 7 on the deuterium treatment tank A and the deuterium treatment tank B is opened, and the deuterium treatment tank B is evacuated. The deuterium gas in the body A is transported to the deuterium gas treatment tank body B until the pressure is balanced, and then the first solenoid valve 5 on the deuterium gas treatment tank body B is opened, and the air inlet pipe 1 replenishes the deuterium gas to the deuterium gas treatment tank body B until the deuterium gas concentration and air pressure in the deuterium gas treatment tank body B reach the preset value and then stops. The deuterium gas treatment tank body B performs deuterium treatment on the optical fiber; during the deuterium treatment process of the optical fiber, the remaining deuterium gas treatment tank bodies 4 also adopt the above operation to circulate the deuterium gas in multiple deuterium gas treatment tank bodies 4, realizing the recycling and intelligent scheduling of deuterium gas, significantly reducing the deuterium gas consumption in the optical fiber production process, thereby reducing the optical fiber production cost and enhancing the market competitiveness of the enterprise.

[0019] Preferably, but not limited to, the air intake pipe 1 is connected to a pressure balancing pipe 14 having a fifth solenoid valve 13. The pressure balancing pipe 14 is configured to communicate with an external air intake device. The external air pressure device delivers air to the deuterium processing tank 4 through the pressure balancing pipe 14, thereby adjusting the deuterium concentration and pressure within the deuterium processing tank 4.

[0020] The optical fiber deuterium treatment process consumes a small amount of deuterium gas, and the air in the tank will not be 100% exhausted during vacuuming, which will cause the deuterium concentration to decrease. The deuterium concentration in each deuterium treatment tank 4 is 2%, and the air pressure is 0.05 MPa, which can eliminate the hydrogen loss defect of the optical fiber.

[0021] The deuterium concentration in the deuterium gas source 3 is 3%, and the vacuum pressure of the vacuum pump 12 is 0.08 MPa, so that during the long-term operation of the deuterium gas processing intelligent circulation scheduling system, the deuterium concentration decreases significantly with the number of cycles. When the number of cycles reaches infinite, the deuterium concentration tends to stabilize at 2%, meeting the optical fiber deuterium processing requirements.

[0022] The control system is electrically connected to a reaction time module and a touch display, and the touch display is used to display the deuterium gas concentration, air pressure and reaction time of each deuterium gas treatment tank 4, so that the operator can intuitively understand the working status of each deuterium gas treatment tank 4; the touch display is also provided with a touch switch button, a touch emergency stop button and a touch start and stop button; the touch switch button is used to control the working status of the first solenoid valve 5, the second solenoid valve 7, the third solenoid valve 9, the fourth solenoid valve 10, the fifth solenoid valve 13 and the vacuum pump 12; the touch emergency stop button is used to control the emergency stop of the deuterium gas treatment intelligent circulation scheduling system; the touch emergency stop button is used to turn off or start the deuterium gas treatment intelligent circulation scheduling system; the setting of the touch switch button, the touch emergency stop button and the touch start and stop button can facilitate the operator to manually control the entire deuterium gas treatment intelligent circulation scheduling system.

[0023] In summary, the intelligent circulation scheduling system for deuterium gas processing of the present invention controls multiple deuterium gas processing tanks 4 so that deuterium gas is circulated in multiple deuterium gas processing tanks 4, thereby realizing the recycling and intelligent scheduling of deuterium gas, significantly reducing the deuterium gas consumption in the optical fiber production process, thereby reducing the optical fiber production cost and enhancing the market competitiveness of the enterprise.
