Description

Technical Field

[0001] The present invention mainly relates to the technical field of carbon emission monitoring, and specifically relates to a carbon emission monitoring device for polyester fiber production. Background Art

[0002] Polyester fiber (PET fiber) is produced using terephthalic acid (PTA) and ethylene glycol (EG) as raw materials through polymerization and spinning processes. During the production process, energy consumption (fossil fuel combustion) and process reactions (conversion of carbon-containing compounds) generate carbon emissions. During the production and processing of existing polyester fibers, carbon emissions generated by production are monitored through monitoring equipment, which is mainly divided into online monitoring and offline monitoring. Online monitoring can achieve real-time monitoring by installing monitoring equipment at the exhaust port, but this monitoring method usually has large monitoring data errors and the monitoring equipment is easily damaged. Offline monitoring uses a syringe or pump to collect exhaust gas into the box, and then monitors after collecting a certain amount of gas. This method can improve the accuracy of monitoring data and extend the service life of the monitoring equipment, but this monitoring method cannot achieve real-time monitoring. Since offline monitoring requires comparative analysis of multiple monitoring data, it is necessary to manually and precisely control the amount of gas collected each time, which not only increases the workload, but also easily affects the reliability of the data due to human errors; and when collecting through a syringe or pump, the initial residual air inside the box mixes with the collected carbon emission gas, which will directly affect the accuracy of the gas concentration, resulting in distortion of the monitoring results and errors in the data monitored by the monitoring equipment. Summary of the Invention

[0003] The technical solution of the present invention solves the technical problem that the offline monitoring equipment proposed in the above background technology is that the quantitative collection operation is cumbersome when collecting gas, and there is gas inside the box itself, which causes the collected gas to mix with the gas inside the box, affecting the concentration of the collected gas and causing the monitoring data error to increase.

[0004] The technical solution adopted by the present invention to solve the above technical problems is: A carbon emission monitoring device for polyester fiber production, comprising a box body and a box base for supporting and placing the box body, the box body being provided with a collection component for maintaining the interior of the box body in a vacuum state, and the collection component being used to collect and tighten carbon emission gas into the box body, the box body being provided with a drive component for maintaining the stability of the airflow when the collection component collects gas, the interior of the box body being provided with a laser sensor and a laser receiver for monitoring the collected gas, the box base being provided with a protective component for protecting the laser sensor, and the box body being provided with a control component for controlling the opening and closing states of the protective component.

[0007] Preferably, a first infusion block is provided on the support shell, and a first insertion rod is fixedly installed on the support block away from the motor. The end of the first insertion rod away from the support block is inserted into the hole of the first infusion block, and a first spring is sleeved on the first insertion rod.

[0008] Preferably, the driving assembly includes a driving housing, which is arranged on one side of the box body. A hole is provided inside the driving housing and is connected to a hole provided in the first infusion block through a connecting tube.

[0009] Preferably, a connecting rod is slidably connected inside the driving housing, an adsorption block is fixedly installed at one end of the connecting rod located inside the box body, a push block is fixedly installed at one end of the connecting rod away from the adsorption block, and a second spring is sleeved on the connecting rod.

[0010] Preferably, the control assembly includes a rotating rod, which is rotatably connected to the box body, a connecting block is fixedly mounted on one end of the rotating rod, a baffle is fixedly mounted on the connecting block, and a transmission ring is provided at one end of the connecting block away from the baffle.

[0011] Preferably, a transmission block is slidably connected in a groove provided inside the transmission ring, a second infusion block is provided on the transmission ring, and the inner cavity of the second infusion block is communicated with the groove provided in the transmission ring, the second infusion block is slidably connected to an insertion rod on the side away from the transmission ring, a push plate is fixedly installed on the end of the insertion rod away from the second infusion block, and a third spring is sleeved on the second infusion block and the insertion rod.

[0012] Preferably, the protective component includes a protective shell, which is hinged on the box base, and the box base is provided with a ventilation hole on the lower side of the protective shell. The box base has a hole inside which a push rod is slidably connected, and the push rod is hinged with a linkage block at one end away from the hole, and the linkage block is hinged to the protective shell at one end away from the push rod, and a fourth spring is sleeved on the push rod.

[0013] Preferably, the protective component also includes a third infusion block, the third infusion block is arranged on the box base, and the inner cavity of the third infusion block is connected to the box base through a hole, the third infusion block is slidably connected to the third infusion block, and a lower pressure block is fixedly installed on the end of the extrusion rod away from the third infusion block, the lower pressure block is provided with a first limiting block, and the box base is provided with a second limiting block, and the first limiting block and the second limiting block conflict with each other.

[0014] Compared with the prior art, the present invention has the following beneficial effects: the collection component uses a vacuum pump to evacuate the interior of the box body to a vacuum state, and then uses the pressure difference between the inside and outside of the box to drive the collection tube to inhale carbon emission gas. The collection process is automatically started and stopped based on the change of the pressure difference between the inside and outside of the box. When the gas in the box is sufficient to the point where the pressure difference cannot continue to inhale, the collection automatically terminates the vacuum environment. This not only prevents other gases in the box itself from mixing with the collected gas and affecting the normal concentration of the collected gas, but also collects gas through vacuum pressure to ensure that the amount of gas collected inside the box body each time is basically consistent, which can reduce the error in the carbon emission gas monitoring data. The core of carbon emission monitoring is to calculate emissions by collecting gas concentrations. However, unstable airflow will cause the collected gas samples to not truly reflect the actual state of the emission source. The driver component adjusts the diameter of the collection tube according to the changes in the air pressure inside the box (the tube diameter expands when the air pressure inside the box is high, and the tube diameter shrinks when the air pressure is low) to compensate for the pressure fluctuations inside the box. As the vacuum degree gradually decreases with the entry of gas (that is, the air pressure inside the box gradually increases), the airflow pressure inside the tube is maintained stable by changing the diameter of the collection tube, ensuring a uniform airflow velocity, avoiding fluctuations in the laser sensor receiving signal due to unstable airflow, and reducing errors in carbon emission monitoring. When the inside of the box body is in a vacuum state, the negative pressure environment will damage the laser sensor and affect the accuracy of the laser sensor. When the inside of the box body is in a vacuum state and the box body is collecting gas to enter the inside of the box body, the protective component is in a closed state to prevent the inside of the box body from having a large pressure that affects the accuracy of the laser sensor; when there is enough gas collected inside the box body, and the air pressure inside the box body is not enough to draw the gas into the inside of the box body, the protective component is opened, and the carbon emissions can be monitored by the laser sensor. In this way, the service life of the laser sensor can be improved.

[0017] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0018] Please refer to the attached Figures 1-10, including a box body 1 and a box base 12 for supporting the box body 1, the box body 1 is provided with a collection component 2 for keeping the inside of the box body 1 in a vacuum state, and the collection component 2 is used to collect carbon emission gas into the box body 1, the box body 1 is provided with a driving component 3 for maintaining the stability of the airflow when the collection component 2 collects gas, the inside of the box body 1 is provided with a laser sensor 6 and a laser receiver 61 for monitoring the collected gas, the box base 12 is provided with a protective component 5 for protecting the laser sensor 6, and the box body 1 is provided with a control component 4 for controlling the opening and closing state of the protective component 5.

[0019] The specific operation process of the present invention is as follows: the air inside the box body 1 is extracted through the collection component 2, so that the inside of the box body 1 is in a vacuum state. At this time, the control component 4 drives the protective component 5 to be in a closed state. The protective component 5 covers the laser sensor 6 to play a protective role. When the inside of the box body 1 is in a vacuum state, the drive component 3 is opened by the control component 4. The pressure generated by the vacuum state inside the box body 1 drives the drive component 3. At this time, the drive component 3 opens the collection component 2, and the collection component 2 starts to collect carbon emission gas. During the collection process, the control component 4 still controls the protective component 5 to be in a closed state. The collection component 2 collects gas through the vacuum pressure inside the box body 1. As the gas enters the box body 1 Inside, the vacuum degree inside the box body 1 decreases (the internal air pressure gradually balances with the outside), and the pressure generated inside the box body 1 decreases. As the internal pressure of the box body 1 decreases, the driving component 3 begins to adjust the pressure of the collection component 2 itself. In this way, even if the internal pressure of the box body 1 decreases, the collection component 2 increases the pressure to compensate for the reduced pressure of the box body 1, so that the gas flow collected by the collection component 2 remains stable. When enough gas is collected inside the box body 1, the internal air pressure of the box body 1 tends to the set value, and there is no need to continue collecting gas. At this time, the driving component 3 closes the collection component 2, and the control component 4 opens the protection component 5. The carbon emissions of the collected gas inside the box body 1 are monitored through the laser sensor 6 and the laser receiver 61; The laser sensor 6 (using the Siemens ULTRAMAT 23 model (infrared laser principle)) emits a laser of a specific wavelength (such as a 4.26μm infrared laser for CO2) through the collected gas in the box body 1; the laser receiver 61 receives the laser signal after being absorbed by the gas, and calculates the concentration of the carbon component (such as CO2) in the gas by the degree of light intensity attenuation, thereby realizing carbon emission monitoring. Please refer to Figures 1-8The collection component 2 includes a support shell 211, which is fixedly mounted on one side of the box body 1. A collection tube 212 is provided on one side of the box body 1, and the collection tube 212 passes through the interior of the support shell 211. A vacuum pump 213 is provided above the box body 1. Support blocks 214 are slidably connected on both sides of the top of the box body 1. A conveying block 215 is provided on the support block 214. A motor 216 is fixedly mounted on one side of the support block 214. The rotating shaft of the conveying block 215 is fixedly connected to the output end of the motor 216. Rollers 217 are rotatably connected on both sides of the conveying block 215, and the roller 217 on one side is in contact with the collection tube 212.

[0020] The vacuum pump 213 is connected to the inner cavity of the box body 1 through the exhaust pipe, and in the initial state, the driving component 3 will drive the roller 217 on one side to press against the collection tube 212. At this time, the collection tube 212 is in a closed state, and the vacuum pump 213 is started. The vacuum pump 213 extracts the gas inside the box body 1 until the inside of the box body 1 is basically in a vacuum state (in the process of extracting the gas inside the box body 1, the driving component 3 is in a closed state. At this time, the driving component 3 is not linked to the air pressure environment inside the box body 1). When it is necessary to collect carbon emission gas, the driving component 3 is turned on at this time. The driving component 3 contacts the air pressure inside the box body 1. The vacuum negative pressure state inside the box body 1 will drive the driving component 3 to move toward the inner cavity of the box body 1. At this time, the roller 217 pressing against the collection tube 212 is extracted by the driving component 3. At this time, the diameter of the collection tube 212 is opened to the maximum state, and the vacuum pump 213 is started at the same time. The motor 216 is driven, and the motor 216 drives the conveying block 215 to rotate through the rotating shaft. The conveying block 215 drives the rollers 217 on both sides to rotate along the collection tube 212 inside the support shell 211. The collection tube 212 collects carbon emission gas through the vacuum pressure inside the box body 1. As the gas enters the box body 1, the internal air pressure inside the box body 1 gradually balances with the external pressure, and the pressure begins to decrease. At this time, the internal air pressure of the box body 1 decreases (the pressure on the drive component 3 decreases), and the drive component 3 begins to slowly push the rollers 217 inward. At this time, the rollers 217 squeeze the collection tube 212, and the inner diameter of the collection tube 212 decreases and the pressure increases to compensate for the reduced pressure inside the box body 1. The rollers 217 compress the collection tube 212 and move along the collection tube 212. The compressed area changes continuously, so that the inner cavity of the collection tube 212 is similar to a piston to transport gas, thereby ensuring the stability of gas transportation.

[0021] Please refer to Figure 7-10A first infusion block 220 is provided on the support shell 211, and a first insertion rod 218 is fixedly installed on the support block 214 on the side away from the motor 216. The end of the first insertion rod 218 away from the support block 214 is inserted into the hole of the first infusion block 220, and a first spring 219 is sleeved on the first insertion rod 218. The driving assembly 3 includes a driving shell 31, which is provided on one side of the box body 1. A hole is opened inside the driving shell 31 and is connected to the hole opened in the first infusion block 220 through a connecting pipe 221. A connecting rod 33 is slidably connected inside the driving shell 31, and an adsorption block 34 is fixedly installed on one end of the connecting rod 33 on the inner side of the box body 1. A push block 32 is fixedly installed on the end of the connecting rod 33 away from the adsorption block 34, and a second spring 35 is sleeved on the connecting rod 33.

[0022] The interior of the box body 1 is in a vacuum state, and the hole of the adsorption block 34 provided inside the box body 1 is opened. The internal pressure of the box body 1 drives the adsorption block 34 to move backward, and the adsorption block 34 pulls the connecting rod 33 and the push block 32 to move backward. At this time, the second spring 35 is in a stretched state, and the push block 32 moves backward to make room for a part of the inner cavity of the drive housing 31. A sealing ring is provided on the push block 32, and the whole is configured as a piston. The inner cavity of the drive housing 31 and the first-level connecting pipe 221 of the inner cavity of the first infusion block 220 are both provided with hydraulic oil. , and the first insertion rod 218 is inserted into the hole of the first infusion block 220 and a piston is provided at one end. When the push block 32 moves forward to make room, the first spring 219 begins to contract and drives the first insertion rod 218 to insert more into the first infusion block 220. At this time, the hydraulic oil is squeezed into the inner cavity of the drive housing 31. At this time, the first insertion rod 218 drives the first support block 214 to move backward, and the roller 217 moves away from the collection tube 212. On the contrary, when the gas inside the box body 1 increases, the roller 217 will move closer to the collection tube 212.

[0023] Please refer to Figure 10 The control component 4 includes a rotating rod 41, which is rotatably connected to the box body 1. A connecting block 42 is fixedly installed at one end of the rotating rod 41, and a baffle 43 is fixedly installed on the connecting block 42. A transmission ring 44 is provided at the end of the connecting block 42 away from the baffle 43. A transmission block 45 is slidably connected in a groove provided inside the transmission ring 44. A second infusion block 46 is provided on the transmission ring 44, and the inner cavity of the second infusion block 46 is connected to the groove provided in the transmission ring 44. A second insertion rod 47 is slidably connected to the side of the second infusion block 46 away from the transmission ring 44. A push plate 48 is fixedly installed on the end of the second insertion rod 47 away from the second infusion block 46. A third spring 49 is sleeved on the second infusion block 46 and the second insertion rod 47.

[0024] When the vacuum pump 213 is exhausted, the rotating rod 41 rotates, and the baffle 43 is rotated to the hole where the adsorption block 34 is provided (the hole where the adsorption block 34 is provided and the inner cavity of the box body 1 are separated by the baffle 43). At this time, the transmission ring 44 is at the bottom, which will press down the protective component 5 to close the protective component 5. When the inside of the box body 1 is in a vacuum state and carbon emission gas needs to be collected, the rotating rod 41 is rotated 180°. At this time, the transmission ring 44 rotates to the top (at this time, the baffle 43 is turned away from the hole, and the hole and the inner cavity of the box body 1 are connected to each other. The baffle 34 is rotated to the bottom, but the baffle 34 does not press down the protective component 5). At this time, the box body 1 draws out the adsorption block 34 through the vacuum pressure. The transmission block 45 has an inclined surface at the beginning. The adsorption block 34 is drawn out and inserted into the transmission ring 44. The adsorption block 34 contacts the transmission block 45 along the transmission block. The inclined surface of 45 moves backward, pressing the transmission block 45 down into the groove of the transmission ring 44. Hydraulic oil is provided in the groove of the transmission ring 44, and hydraulic oil is also provided inside the second infusion block 46. When the transmission block 45 is pressed down, the hydraulic oil in the groove is squeezed into the second infusion block 46. The second plug rod 47 is inserted into the second infusion block 46 and a piston is provided at one end. The hydraulic oil pushes the second plug rod 47 to extend. At this time, the second plug rod 47 drives the push plate 48 to press down on the top of the protective component 5, driving the protective component 5 to close, and at this time the third spring 49 is in a stretched state. As the gas inside the box body 1 increases and the pressure decreases, the adsorption block 34 is pulled out from the inside of the transmission ring 44 under the action of the second spring 35. At this time, the transmission block 45 is not pressed down. At this time, the third spring 49 drives the second plug rod 47 and the push plate 48 to rise and reset. The protective component 5 is unpressed and is in an open state. At this time, the laser sensor 6 is exposed inside the box body 1 to monitor carbon emissions.

[0025] Please refer to Figure 6 The protective assembly 5 includes a protective shell 51, which is hinged on the box base 12. The box base 12 is provided with a ventilation hole 13 on the lower side of the protective shell 51. The box base 12 has a hole inside which a push rod 57 is slidably connected. The push rod 57 is hinged with a linkage block 59 at one end away from the hole. The linkage block 59 is hinged to the protective shell 51 at one end away from the push rod 57. A fourth spring 58 is sleeved on the push rod 57. The protective assembly 5 also includes a third infusion block 54. The third infusion block 54 is provided on the box base 12, and the inner cavity of the third infusion block 54 is connected to the hole provided in the box base 12. The third infusion block 54 is slidably connected with an extrusion rod 53. The extrusion rod 53 is fixedly installed with a lower pressing block 52 at one end away from the third infusion block 54. A first limiting block 55 is provided on the lower pressing block 52, and a second limiting block 56 is provided on the box base 12. The first limiting block 55 and the second limiting block 56 conflict with each other.

[0026] Hydraulic oil is provided inside the inner cavity of the third infusion block 54 and the box base 12. When the lower pressing block 52 is pressed down, the lower pressing block 52 inserts more of the extrusion rod 53 into the inner cavity of the third infusion block 54, and the extrusion rod 53 inserted into the inner cavity of the third infusion block 54 is provided with a piston, and the push rod 57 is inserted into the part of the inner cavity of the box base 12 storing the hydraulic oil. The extrusion rod 53 squeezes the hydraulic oil in the inner cavity of the third infusion block 54 into the inner cavity of the box base 12, and the push rod 57 is pushed outward. The push rod 57 pushes the linkage block 59 forward, and the protective shell 51 is pushed to cover the laser sensor. The push rod 57 pulls the linkage block 59 into the groove of the box base 12. At this time, the protective shell 51 is pulled and rotated 90 degrees to be in the open state, and the push rod 57 squeezes the hydraulic oil into the third infusion block 54, driving the extrusion rod 53 and the lower pressure block 52 to rise. The first limiting block 55 and the second limiting block 56 are used to limit the rising height of the lower pressure block 52, and the ventilation hole 13 is used to replace the internal gas before the protective shell 51 is opened.

[0027] The above description of the present invention is exemplified in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
