Description

Technical Field

[0001] This invention relates to the field of chlorine control, and more particularly to a chlorine control device. Background Technology

[0002] In the carbon production process, chlorine is an important component of the reaction and can affect the quality of the final carbon product. Therefore, in the actual carbon production process, the introduction of chlorine needs to be precisely controlled. This is because changes in parameters such as the concentration and flow rate of chlorine have a significant impact on the reaction process. Of course, the chlorine actually introduced is not 100% chlorine, but a mixture of chlorine and inert gases in a certain percentage.

[0003] In existing technologies, chlorine flow control is generally achieved by using a volumetric flow meter to precisely control the volumetric flow rate of chlorine. However, in low-temperature environments, even if the volumetric flow rate of chlorine is controlled to be the same by the volumetric flow meter, the chlorine gas will contract due to the temperature, resulting in a different output chlorine concentration than the set value. Low-concentration chlorine has limited purification effect and cannot completely remove other impurities, while high-concentration chlorine may lead to an increase in the generation of by-products, directly affecting the product quality of carbon production. Summary of the Invention

[0004] The purpose of this invention is to provide a chlorine control device to improve the problem that the concentration of chlorine cannot be controlled at low temperatures in the prior art.

[0005] A chlorine gas control device includes a housing, an inlet pipe connected to one side of the housing, an outlet pipe connected to the other side of the housing, a regulating box connected between the inlet pipe and the outlet pipe, the regulating box being located inside the housing, the regulating box being used to regulate the chlorine gas concentration, a moving component being provided inside the housing, the moving component being provided with symmetrically distributed heating plates, the heating plates being used to heat the chlorine gas in the regulating box to regulate the chlorine gas concentration, and the moving component being used to move the heating plates closer to the regulating box.

[0006] More preferably, the moving component includes a synchronization unit and an operation unit, wherein the synchronization unit is used to drive the heating plate to move synchronously, and the operation unit is used to drive the heating plate to move.

[0007] More preferably, the synchronization unit includes symmetrically distributed fixed rods, rotating blocks, and swing rods. The symmetrically distributed fixed rods are fixed inside the housing. The rotating blocks are rotatably connected to the fixed rods. An elastic element connects the rotating blocks and the fixed rods. The swing rods rotatably connect adjacent rotating blocks.

[0008] More preferably, the operating unit includes a slide rod and a spring, the slide rod is slidably connected to the swing rod, the slide rod is connected to the heating plate, and the spring is connected between the heating plate and the swing rod.

[0009] More preferably, a first concentration sensor is installed on the air intake pipe, the first concentration sensor is electrically connected to the heating plate, the regulating box is connected to a gas filling pipe, and a solenoid valve is installed on the gas filling pipe, the solenoid valve is electrically connected to the first concentration sensor.

[0010] More preferably, an air storage bladder is installed at the top of the box body, the air storage bladder is connected to the gas filling pipe, and the air storage bladder is connected to a gas delivery pipe.

[0011] More preferably, a first rotating shaft is rotatably connected to the side of the regulating box near the gas filling pipe, and a first stirring blade is connected to the first rotating shaft.

[0012] More preferably, the regulating box has multiple second rotating shafts rotatably connected inside, and second stirring blades are connected to the second rotating shafts. Adjacent second rotating shafts are connected by a transmission belt, and the second rotating shafts close to the first rotating shaft are also connected to the first rotating shaft by a transmission belt.

[0013] More preferably, a second concentration sensor is installed on the gas outlet pipe, which is used to detect the concentration of the output chlorine gas.

[0014] More preferably, a valve is installed on the gas outlet pipe, and the valve is electrically connected to the second concentration sensor.

[0015] Compared with the prior art, the present invention has the following advantages: 1. The present invention controls the opening of the solenoid valve by setting a first concentration sensor, so that the inert gas in the gas storage bag enters the regulating box through the gas filling pipe, mixes with chlorine, neutralizes the chlorine and gradually reduces its concentration, thereby avoiding excessively high chlorine concentration under low temperature conditions. 2. By installing a heating plate, when the first concentration sensor detects that the chlorine concentration does not meet the preset value, the first concentration sensor controls the solenoid valve to open and simultaneously controls the heating plate to start. The heating plate begins to heat up. As the gas in the gas storage bag gradually enters the regulating box, the chlorine concentration gradually returns to normal. At this time, the demand for the heating plate is not high. The gas in the gas storage bag decreases and contracts, and the swing arm is no longer squeezed. Under the reset action of the spring and torsion spring, it gradually resets, causing the heating plate to gradually move away from the regulating box, thereby preventing the chlorine concentration from becoming too low due to dilution and excessively high temperatures. 3. With the first and second stirring blades, when inert gas enters from the gas filling pipe, it will blow onto the first stirring blade, thereby driving the first rotating shaft to rotate. The second stirring blade and the second rotating shaft will then rotate via the transmission belt, so that the gas in the regulating box can be quickly and evenly mixed under the stirring action. 4. By setting a second concentration sensor and a valve, the valve 22 will only open when the chlorine concentration is detected by the second concentration sensor 21 to meet the standard, and the chlorine will flow out from the outlet pipe 3, to prevent the output chlorine concentration from not meeting the standard.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, 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. Unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by those skilled in the art. The terms "comprising" and similar expressions used herein mean that the element or object preceding the word covers the element or object listed after the word and its equivalents, but does not exclude other elements or objects.

[0019] Example 1: This embodiment of the invention provides a chlorine gas control device, such as... Figures 1-3 As shown, the device includes a housing 1, with an inlet pipe 2 connected to the left side of the housing 1 for receiving chlorine gas, and an outlet pipe 3 connected to the right side of the housing 1. A regulating box 4 is connected between the inlet pipe 2 and the outlet pipe 3, located inside the housing 1. The regulating box 4 is used to regulate the concentration of chlorine gas. A first concentration sensor 11 is installed on the inlet pipe 2. The regulating box 4 is connected to a gas filling pipe 12, which is equipped with a solenoid valve 13. The solenoid valve 13 is electrically connected to the first concentration sensor 11. A gas storage bladder 14 is installed at the top inside the housing 1 for storing inert gas. The gas storage bladder 14 is connected to the gas filling pipe 12 and a gas delivery pipe 15. A one-way valve is installed on the gas delivery pipe 15 to prevent the gas in the gas storage bladder 14 from overflowing in reverse. The gas in the gas storage bladder 14 is replenished through the gas delivery pipe 15.

[0020] Chlorine gas is introduced into the regulating tank 4 through the inlet pipe 2. In a low-temperature environment, the volume of chlorine gas will shrink due to the temperature. Similarly, the concentration of chlorine gas will also increase in a low-temperature environment, causing the concentration value sensed by the first concentration sensor 11 to be lower than the preset value. The first concentration sensor 11 controls the solenoid valve 13 to open, allowing the inert gas in the gas storage bag 14 to enter the regulating tank 4 through the gas filling pipe 12, mix with the chlorine gas, neutralize the chlorine gas and gradually reduce its concentration, and then the chlorine gas flows out through the outlet pipe 3.

[0021] Example 2: Based on Example 1, such as Figures 3-5 As shown, a movable component is provided inside the housing 1, and symmetrically distributed heating plates 10 are provided on the movable component. The heating plates 10 are electrically connected to the first concentration sensor 11. The heating plates 10 are used to heat the chlorine gas in the regulating tank 4 to regulate the chlorine gas concentration. The movable component is used to move the heating plates 10 closer to the regulating tank 4.

[0022] The moving component includes a synchronization unit and an operation unit. The synchronization unit is used to drive the heating plate 10 to move synchronously, and the operation unit is used to drive the heating plate 10 to move. The synchronization unit includes symmetrically distributed fixed rods 5, rotating blocks 6, and swing rods 7. The symmetrically distributed fixed rods 5 are fixed inside the housing 1. The rotating blocks 6 are rotatably connected to the fixed rods 5. A torsion spring is connected between the rotating blocks 6 and the fixed rods 5 to drive the rotating blocks 6 to reset. A swing rod 7 is rotatably connected between adjacent rotating blocks 6. The upper swing rod 7 is in compression engagement with the air storage bag 14. The operation unit includes a sliding rod 8 and a spring 9. The sliding rod 8 is slidably connected to the swing rod 7 and connected to the heating plate 10. A spring 9 is connected between the heating plate 10 and the swing rod 7.

[0023] Initially, the gas reservoir 14 is filled with gas and is in an inflated state. The inflated reservoir 14 presses against the swing rod 7, causing the upper swing rod 7 to move downwards, thereby driving the rotating block 6 to rotate. This causes the other swing rods 7 to swing inwards, thus pressing the heating plate 10 inwards and against the regulating box 4, compressing the spring 9. When the first concentration sensor 11 detects that the chlorine concentration does not meet the preset value, the first concentration sensor 11 controls the solenoid valve 13 to open and simultaneously controls the heating plate 10 to start. The heating plate 10 begins to heat. As the gas in the gas reservoir 14 gradually enters the regulating box 4, the chlorine concentration gradually returns to normal. At this time, the demand on the heating plate 10 is not high. The gas in the gas reservoir 14 decreases and contracts, and the swing rod 7 is no longer compressed. Under the reset action of the spring 9 and the torsion spring, it gradually resets, causing the heating plate 10 to gradually move away from the regulating box 4, thereby preventing the chlorine concentration from becoming too low due to dilution and excessively high temperatures.

[0024] Example 3: Based on Example 2, such as Figure 6 As shown, a first rotating shaft 16 is rotatably connected to the side of the regulating box 4 near the gas filling pipe 12. A first stirring blade 17 is connected to the first rotating shaft 16. Multiple second rotating shafts 18 are rotatably connected to the regulating box 4. Second stirring blades 19 are connected to the second rotating shafts 18. Adjacent second rotating shafts 18 are connected by a transmission belt 20. The second rotating shaft 18 near the first rotating shaft 16 is also connected to the first rotating shaft 16 by a transmission belt 20.

[0025] To prevent the inert gas from failing to mix evenly with the chlorine gas in a timely manner after being introduced into the regulating tank 4, the inert gas is blown onto the first stirring blade 17 after entering from the gas supply pipe 12, thereby driving the first rotating shaft 16 to rotate. Through the transmission belt 20, the second stirring blade 19 and the second rotating shaft 18 are driven to rotate, so that the gas in the regulating tank 4 can be quickly and evenly mixed under the stirring action.

[0026] Example 4: Based on Example 3, such as Figure 1 and Figure 3 As shown, a second concentration sensor 21 is installed on the gas outlet pipe 3. The second concentration sensor 21 is used to detect the concentration of the output chlorine gas. A valve 22 is installed on the gas outlet pipe 3. The valve 22 is electrically connected to the second concentration sensor 21.

[0027] To prevent the output of chlorine gas from failing to meet the standard, valve 22 will only open and chlorine gas will flow out from outlet pipe 3 when the chlorine gas concentration is detected by the second concentration sensor 21 to meet the standard.

[0028] While embodiments of the present invention have been described in detail above, it will be apparent to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations fall within the scope and spirit of the invention as set forth in the claims. Furthermore, the invention described herein may have other embodiments and can be implemented or carried out in various ways.
