Description
Technical Field
[0001] The invention relates to the technical field of flue gas analyzers, in particular to a portable and foldable flue gas emission rapid analyzer. Background Art
[0002] The most common and frequently used one is the infrared flue gas analyzer, which determines whether the substance is contained inside and detects the concentration changes inside by measuring the degree to which different substances absorb infrared rays of different bands.
[0003] When using the analyzer, some inevitable problems are often encountered. Since dust and water vapor often appear in the flue gas, and the temperature in the detection room changes, the water vapor will condense to varying degrees and stick to the inner wall of the detection room. These water droplets will also attract dust. When the temperature in the detection room rises, it will hinder the detection and the release of heat energy, causing serious interference to the detection. At the same time, during the detection process, due to the irregular flow direction of the flue gas, the gas content in the detection room will fluctuate, interfering with the concentration detection, resulting in the obtained data being inconsistent with the actual data. In addition, the accumulation of some dust at the outlet and inlet will also affect the concentration change in the detection room. During the detection, it is restricted by the detection device, resulting in the single adaptation of the detection device to the site, which seriously narrows the detection range. Summary of the Invention
[0004] The object of the present invention is to provide a portable and foldable flue gas emission rapid analyzer to solve the problems raised in the above background technology.
[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:
[0006] The rapid analyzer includes a flue gas analysis box, which is provided with a display screen and a control panel, a signal access port, which is connected to a flue gas detection component, and a flue gas detection component including a main spindle box, a detection motor is provided in the main spindle box, a collecting roller is provided on the output end of the detection motor, the collecting roller is rotatably connected to the main spindle box, a collecting tube is provided in the collecting roller, an infrared sensor is provided in the collecting tube, the infrared sensor is connected to a circuit substrate via a wire, the circuit substrate is provided in the main spindle box, and the circuit substrate is connected to the signal access port on the flue gas analysis box via a wire, and the flue gas detection component is placed in the main spindle box. It is placed in the area that needs to be inspected, and then the detection motor rotates and finds the best probing position. The collection tube in the collection roller will collect the flue gas in the area and transmit it to the interior. The infrared sensor will detect the flue gas components and flue gas concentration, and transmit the analyzed current to the circuit substrate. The circuit substrate will integrate these electrical signals. The flue gas detection component will transmit the collected information to the flue gas analysis box through the signal access port. The flue gas analysis box will analyze these electrical signals and display the analyzed data on the display screen for the operator to record.
[0007] An infrared sensor is provided in the collecting tube near one end of the spindle box, the infrared sensor includes a reference chamber and a detection chamber, an air inlet and an air outlet are provided on the detection chamber, an air inlet pipe is provided on the air inlet, an air inlet motor is provided in the air inlet pipe, the air inlet pipe is connected with the collecting tube, an air outlet pipe is provided on the air outlet, an exhaust port is provided on the collecting tube, the exhaust port is connected with the exhaust port on the collecting tube, an infrared component is provided on one side of the reference chamber and the detection chamber, a receiving chamber is provided on the side of the reference chamber and the detection chamber away from the infrared component, the receiving chamber is connected to the signal access port on the flue gas analysis box through a wire, the reference chamber and the detection chamber have the same specifications, a multi-section mirror is provided in the infrared sensor, and the multi-section mirror is provided. It is placed on both sides of the detection room and the reference room, and each multi-section mirror is respectively set on a focusing track, which is set on the output end of the focusing motor. The focusing motor is connected to the flue gas analysis box through a wire, and the focusing track is slidably connected to the infrared sensor. The motor in the intake pipe works, and the flue gas enters the intake pipe through the collection pipe and finally reaches the detection room. The reference room is filled with a gas element that does not absorb any infrared energy. The infrared component is turned on, and a filter wheel is set in the infrared component. By adjusting the use of the filter wheel, infrared light of different frequency bands can be emitted. Different gases have different chemical bonds or functional groups, and different absorption frequencies, which will be reflected on the infrared spectrum. In different positions, information about what kind of chemical bonds or functional groups are contained in the molecules can be obtained, and with the use of multi-section mirrors, the refraction direction and reflection direction of infrared light can be adjusted. As time goes by, the content change or content value of the internal component can also be judged. The receiving room will then convert the electrical signal into a tidy signal and transmit it to the flue gas analysis box through a wire. The flue gas analysis box will do data analysis and obtain a specific value. The detection time is short. When the value obtained by the flue gas analysis box is large or small and remains unchanged for a long time, it proves that the internal flue gas concentration is too large or too small. When it is large, due to the limited energy absorption of infrared light waves, the gathering motor will drive The focusing track shrinks, and the shrinking multi-section mirror will allow the infrared light waves reflected or refracted from the outer wall of the detection chamber to re-enter the detection chamber, increasing the range while also enhancing the utilization rate of infrared light. When the internal concentration is low, the value will not change significantly for a long time, and the accurate concentration value cannot be obtained. At this time, the focusing motor will drive the focusing track to shrink, and the shrinking multi-section mirror will allow the infrared light waves reflected or refracted from the outer wall of the detection chamber to re-enter the detection chamber, so that the internal detected substances can make full use of the infrared light, thereby enhancing the detection intensity. When the concentration is normal, the multi-section mirrors remain parallel.
[0008] The detection chamber is provided with a cleaning component, which includes a cleaning rack, which is movably connected to the detection chamber, a telescopic roller is provided in the cleaning rack, and the telescopic roller is slidably connected to the cleaning rack by a spring, and the telescopic roller is against the inner wall of the detection chamber, and the cleaning rack is a cavity structure, and a number of cleaning nozzles are provided on the side of the cleaning rack close to the inner wall of the detection chamber, a pressure plate is provided in the cleaning rack, and an air intake ball is provided at the air inlet of the cleaning rack, and the air intake ball is slidably connected to the cleaning rack by a spring, and the air intake ball is against the air inlet away from the spring end, and a first push plate and a second push plate are provided on the pressure plate, and the first push plate and the second push plate are rotatably connected to the pressure plate by an axis, and the pressure plate is slidably connected to the cleaning rack. During the detection process, water vapor and dust will inevitably appear in the emission of smoke. When they enter the detection chamber, when the infrared component starts working, the temperature in the detection chamber will change, and the temperature change affects the activity of the water vapor and sticks to the inner wall of the detection chamber, and at the same time causes the dust in the smoke to fall on the water vapor formed The air in the cleaning rack is then blown away by the pressure of the rollers as they move upwards, leaving marks on the dry dust. When the rollers are unable to move, gas is ejected from the cleaning nozzles, forming multiple air columns under the action of pressure. At this time, the rollers move downwards, and during the movement, the air columns will hit the marks left by the rollers during their ascent. Under the action of strong air pressure, a large amount of dust will be separated from the inner wall. Dust that has not separated from the inner wall will also be affected by the gas, creating an air barrier between the dust and the inner wall of the testing chamber, and will be knocked down by the rollers during their descent, thus completely removing the dry dust. The dry dust will also flow out of the testing chamber with the gas flow in the testing chamber.
[0009] The telescopic roller includes a cleaning roller, which is slidably connected to the cleaning frame through a telescopic connecting rod, and the cleaning roller is against the wall of the detection chamber. A cleaning cam is provided in the cleaning roller, and the cleaning cam is fixedly connected to the rotating shaft on the cleaning roller. A cleaning rod is provided at one end of the telescopic connecting rod near the cleaning roller and is slidably connected to the cleaning rod through a spring, and the cleaning cam is against the cleaning rod. The cleaning rod includes an embedded rod and a falling rod, and a falling rod is provided in the embedded rod. The falling rod is slidably connected to the embedded rod through a spring, and two falling hammers are provided on the falling rod. Each falling hammer is rotatably connected to the end of the falling rod away from the spring through a spring shaft. The telescopic roller cleaning roller will drive the cleaning roller to move during its movement. The cam rotates, the cleaning cam rotates and moves against the cleaning rod, and the cleaning tube reciprocates in the direction of the telescopic connecting rod. During the movement, the farthest position reached by the embedded rod in the cleaning rod is the position of the inner wall of the detection chamber, so that the embedded rod will penetrate into the contaminants on the inner wall, and the internal shedding rod will also move toward the inner wall of the detection chamber due to inertia and the action of the spring. When the embedded rod returns, the shedding hammer on the shedding rod will rotate due to the action of inertia and the spring, and hit the impurities. As the cleaning roller moves, the shedding hammer will pry the impurities on the inner wall of the detection chamber, and the impurities that have not fallen off will also loosen from the inner wall of the detection chamber.
[0010] The detection room is provided with a flow guide component, which is arranged above the cleaning component. The flow guide component includes a flow guide box, which is arranged between the air inlet pipe and the air outlet pipe. A flow guide disc is arranged in the flow guide box. A spiral flow guide groove is arranged on the side of the flow guide disc close to the cleaning frame. A runner is arranged on the side of the flow guide disc away from the runner groove. The runner on the flow guide disc is connected to the air inlet pipe and the air outlet pipe through a crawler. During the detection process, the irregular flow of smoke will cause the concentration of various components in the detection room to change to a certain extent, and dust accumulation is likely to occur, affecting the detection effect, and some substances are not detected in time. The exhaust gas is discharged at the same time, which will also produce the effect of continuous detection, thereby affecting the detection accuracy. The air intake motor in the air intake pipe provides power for the guide disc. The rotation of the guide disc drives the guide groove to rotate. The guide groove is spiral, which will guide the smoke in the detection room to form a cyclone. While ensuring the smoke concentration, the gas at the air inlet can also be moved to fit the inner wall of the detection room, reducing the adsorption of dust on the inner wall of the detection room. At the same time, the cyclone formed can effectively reduce the impact of the smoke on the detection room when it enters the detection room, reduce the generation of excess energy on the smoke, and ensure monitoring accuracy.
[0011] The air intake pipe and the air outlet pipe are respectively provided with air guide turbines. The air guide turbines in the air intake pipe are connected to the output end of the air intake motor in the air intake pipe. Each air guide turbine is connected to the guide disc through tracks. The air guide turbine blades in the air intake pipe and the air outlet pipe are in opposite directions. The free-flowing flue gas will also gather due to water vapor, and the internal pressure will be greater than the external pressure. As the pressure increases, the particle size of the polymer will increase, which will absorb most of the energy of the infrared component and cause energy loss, resulting in inaccurate detection accuracy. The guide disc Rotating under the action of the air intake motor, the guide groove can fully mix the internal flue gas, which speeds up the flow of the flue gas and reduces the aggregation of water vapor on other substances. The air guide turbines at both ends have the same speed and opposite directions, which can balance the internal air pressure. Under the action of the guide groove, negative pressure will be generated near the air inlet and outlet, which enhances the flue gas flow speed at the air inlet and outlet, and cooperates with the air guide turbine to increase the speed of air intake and exhaust, reducing the problem of reduced air intake and outlet volume caused by blockage of the air inlet and outlet due to dust.
[0012] The collecting roller is a multi-section structure. The top section of the collecting roller is connected to the output end of the detection motor. The adjacent collecting rollers are rotatably connected by a rotating connecting rod. Each collecting roller is provided with a downwind paddle. A rotating shaft is provided in the collecting roller. The rotating shaft is rotatably connected to the collecting roller. A rotating motor is provided in the collecting roller. The output end of the rotating motor is connected to the rotating connecting rod. A rotating electrode is provided at the input end of the rotating motor. The rotating electrode is rotatably connected to the rotating motor. The output end of the rotating electrode is against the input end of the rotating motor and is connected. A trigger paddle is provided at the input end of the rotating electrode. A spring is provided on the rotating shaft. The end of the spring away from the rotating shaft is against the trigger roll. The trigger roll is against the trigger paddle. The weights of the trigger ends at both ends of the rotating electrode are different. When the position inside the detected area changes, the collecting roller will undergo corresponding posture correction to adapt to various terrains. When the direction of the smoke flow changes, under the action of the downwind paddle, the wind will carry a section The collecting roller rotates to adapt to the optimal angle of wind direction, and the rotating shaft inside the collecting roller rotates and drives the spring to rotate. When the rotating shaft is consistent with the flow direction of the flue gas, the rotating shaft has the highest speed. At this time, through the transmission of the coupling group, the spring indirectly connected to the rotating shaft is in the longest state, the triggering reel will maintain the maximum deformation and resist the triggering paddle, the rotating motor will not rotate and will be in a locked state. When the speed of the rotating shaft decreases, the elongation of the spring will decrease, the deformation of the triggering reel will also decrease, the triggering paddle will also release the rotating electrode, and the rotating motor will rotate until the speed of the rotating shaft returns to perpendicular to the flow direction of the flue gas. When the collecting roller is correcting its posture, the rotating electrode will rotate. The rotating motor is a DC motor, and the DC motor will also rotate in different directions, thereby adjusting the posture of the collecting roller to better adapt to the flue gas emission area.
[0013] An anti-touch end is provided at the bottom end of the collecting roller, and the anti-touch end is sleeved on the collecting tube. Several anti-collision buttons are provided on the anti-touch end, and each anti-collision button is respectively against the alarm shrapnel. The alarm shrapnel is provided inside the anti-touch end, and the alarm shrapnel is connected to the flue gas analysis box through a wire. When the collecting roller is correcting its posture or probing, its specific depth cannot be determined due to the obstruction of the flue gas. When the anti-touch end touches the top or the pipe with a more special posture change, the anti-collision button will be triggered, and the electrical signal will be transmitted into the flue gas analysis box through the alarm shrapnel, and the alarm signal will be triggered. At this time, the operator will adjust the posture to avoid damage to the flue gas detection component.
[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. The present invention has a cleaning component for the inner wall of the detection chamber. During the detection process, temperature changes affect the activity of water vapor and adhere to the inner wall of the detection chamber. At the same time, it causes dust in the flue gas to fall on the water film formed by water vapor. As the temperature in the detection chamber rises, dry dust blocks appear on the detection wall, affecting the light transmittance of the detection chamber wall. The cleaning component will clean it regularly, using a combination of high air pressure and high vibration to completely remove impurities on the inner wall of the detection chamber, while also reducing damage to the detection chamber.
[0015] 2. The present invention has a guide component. During the detection process, the irregular flow of flue gas will cause the concentration of various components in the detection room to change to a certain extent, and dust accumulation is likely to occur, affecting the detection effect. Moreover, if some substances are not discharged in time, the effect of continuous detection will occur, thereby affecting the detection accuracy. The guide component will guide it and form a cyclone to ensure the concentration of the flue gas in the detection room. At the same time, the formed cyclone can effectively reduce the impact of the flue gas on the detection room when it enters the detection room, reduce the generation of excess energy on the flue gas, and ensure monitoring accuracy.
[0016] 3. The detection component of the present invention has the function of automatically deforming and changing the direction of exploration. Since the terrain and environment detected by the detection device are different, the restrictions will also be greatly increased. The detection device can automatically adjust the posture of the collection roller according to the changes in the detection environment, through the flow direction and flow speed of the gas to better adapt to the area of flue gas emission, so that the detection equipment can increase the detection range while effectively avoiding the problem of collision damage caused by the equipment during the detection process. Moreover, since the position change is in the center of the air flow, the detection accuracy is guaranteed.
[0017] 4. The present invention adopts a multi-section mirror detection method to avoid measurement errors caused by excessively high or low smoke concentrations. The use of an adjustable mirror angle can also increase the energy utilization rate of infrared light, expand the detection range, and increase measurement flexibility.

The smoke analysis box will analyze these electrical signals and display the analyzed data on the display screen for the operator to record.
[0032] An infrared sensor 11 is provided in the collecting tube 10 near one end of the spindle box 6. The infrared sensor 11 includes a reference chamber 14 and a detection chamber 15.

An air inlet motor 1504 is provided in the air inlet pipe 1503. The air inlet pipe 1503 is communicated with the collecting tube 10. An air outlet pipe 1505 is provided on the air outlet 1502. An exhaust port is provided on the collecting tube 10. The exhaust port 1505 is communicated with the exhaust port on the collecting tube 10.

The motor in the air intake pipe works, and the flue gas enters the air intake pipe through the collection pipe and finally reaches the detection chamber. The reference chamber is filled with a gas element that does not absorb any infrared energy. Turn on the infrared component. A filter wheel is provided in the infrared component, which can be adjusted by using the filter wheel. Depending on the situation, infrared light of different frequency bands is emitted. Different gases have different chemical bonds or functional groups, and different absorption frequencies. They will be in different positions on the infrared spectrum, so that information about what chemical bonds or functional groups are contained in the molecules can be obtained. In conjunction with the use of multi-section mirrors, the refraction direction and reflection direction of the infrared light can be adjusted. As time goes by, the content change or content value of the internal component can also be judged. The receiving room will then convert the electrical signal into something and transmit it to the flue gas analysis box through a wire. The flue gas analysis box will perform data analysis and obtain specific values. The detection time is short. When the value obtained by the flue gas analysis box is large or small and remains unchanged for a long time, it proves that the internal flue gas concentration is too large or too small. At this time, due to the limited energy absorption of infrared light waves, the focusing motor will drive the focusing track to shrink. The shrinking multi-section mirror will allow the infrared light waves reflected or refracted from the outer wall of the detection chamber to re-enter the detection chamber, increasing the range while enhancing the utilization rate of infrared light.

A spiral flow guide groove 1803 is provided on the side of the flow guide disc 1802 close to the cleaning frame 1506. A runner is provided on the side of the flow guide disc 1802 away from the flow guide groove 1803. The runner on the flow guide disc 1802 is connected to the air inlet pipe 1503 and the air outlet pipe 1505 through a crawler. During the detection process, the irregular flow of smoke will cause the concentrations of various components in the detection chamber to fluctuate. It will produce certain changes and easily generate dust accumulation, which will affect the detection effect. Moreover, if some substances are not discharged in time, it will also produce the effect of continuous detection, thereby affecting the detection accuracy. The air intake motor in the air intake pipe provides power for the guide disc. The rotation of the guide disc drives the guide groove to rotate. The guide groove is spiral, which will guide the smoke in the detection room to form a cyclone. While ensuring the smoke concentration, the gas at the air inlet can also be moved to fit the inner wall of the detection room, reducing the adsorption of dust on the inner wall of the detection room. At the same time, the cyclone formed can effectively reduce the impact of the smoke on the detection room when it enters the detection room, reduce the generation of excess energy on the smoke, and ensure monitoring accuracy.
[0036] An air guide turbine 1804 is provided in the air inlet pipe 1503 and the air outlet pipe 1505 respectively. The air guide turbine 1804 in the air inlet pipe 1503 is connected to the output end of the air intake motor 1504 in the air inlet pipe 1503. Each air guide turbine 1804 is connected to the guide disc 1802 via tracks. The blades of the air guide turbine 1804 in the air inlet pipe 1503 and the air outlet pipe 1505 are in opposite directions. The free-flowing flue gas will also gather due to water vapor, and the internal pressure will be greater than the external pressure. As the pressure increases, the particle size of the polymer will increase, which will absorb most of the energy of the infrared component. It also causes energy loss, resulting in inaccurate detection accuracy. The guide disc rotates under the action of the air intake motor, and the guide groove can fully mix the internal flue gas, which speeds up the flow of the flue gas and reduces the aggregation of water vapor to other substances. The air guide turbines at both ends have the same speed and opposite directions, which can balance the internal air pressure. Under the action of the guide groove, negative pressure will be generated near the air inlet and outlet, which enhances the flue gas flow speed at the air inlet and outlet, and cooperates with the air guide turbine to increase the speed of air intake and exhaust, reducing the problem of reduced air intake and outlet volume caused by blockage of the air inlet and outlet caused by dust.
[0037] The collecting roller 9 is a multi-section structure. The top section of the collecting roller 9 is connected to the output end of the detection motor 8. The adjacent collecting rollers 9 are connected in rotation through a rotating connecting rod 19. Each collecting roller 9 is provided with a downwind paddle 901. A rotating shaft 902 is provided in the collecting roller 9. The rotating shaft 902 is connected in rotation with the collecting roller 9. A rotating motor 903 is provided in the collecting roller 9. The output end of the rotating motor 903 is connected to the rotating connecting rod 19. The input end of the rotating motor 903 is provided with a rotating electrode 904. The rotating electrode 90 4 is rotatably connected to the rotating motor 903, and the output end of the rotating electrode 904 is connected to the input end of the rotating motor 903. The input end of the rotating electrode 904 is provided with a trigger paddle 905. A spring is provided on the rotating shaft 902. The end of the spring away from the rotating shaft 902 is pressed against the trigger roll 906. The trigger roll 906 is pressed against the trigger paddle 905. The trigger ends of the rotating electrode 904 have different weights. When the position inside the detected area changes, the collecting roller will undergo corresponding posture correction to adapt In various terrains, when the direction of smoke flow changes, under the action of the downwind paddle, the wind will cause a section of the collecting roller to rotate, adapting to the optimal angle of the wind direction. The follower shaft in the collecting roller rotates and drives the spring to rotate. When the follower shaft is consistent with the flow direction of the smoke, the speed of the follower shaft is the highest. At this time, through the transmission of the coupling group, the spring indirectly connected to the follower shaft is in the longest state, the trigger reel will maintain the maximum deformation and resist the trigger paddle, the rotating motor will not rotate and will be in a locked state. When the speed of the follower shaft decreases, the elongation of the spring will decrease, the deformation of the trigger reel will also decrease, the trigger paddle will also release the rotating electrode, and the rotating motor will rotate until the speed of the follower shaft returns to perpendicular to the direction of smoke flow. When the collecting roller is correcting its posture, the rotating electrode will rotate. The rotating motor is a DC motor, and the DC motor will also rotate in different directions, thereby adjusting the posture of the collecting roller to better adapt to the area of smoke emission.
[0038] The bottom end of the collecting roller 9 is provided with an anti-touch end 908, which is sleeved on the collecting tube 10.

The alarm shrapnel 910 is connected to the flue gas analysis box 1 through a wire. When the collecting roller is correcting its posture or probing, its specific depth cannot be determined due to the obstruction of the flue gas. When the anti-touch end reaches the top or the pipe with a more special posture change, the anti-collision button will be triggered, and the electrical signal will be transmitted into the flue gas analysis box through the alarm shrapnel, and the alarm signal will be triggered. At this time, the operator will adjust the posture to avoid damage to the flue gas detection component.
[0039] The working principle of the present invention is as follows: the smoke detection component 5 is placed in the area to be inspected, and then the detection motor 8 rotates and finds the best detection position. When the position inside the detected area changes, the collection roller 9 will undergo corresponding posture correction to adapt to various terrains, thereby adjusting the posture of the collection roller 9 to better adapt to the area of smoke emission. The air intake motor 1504 in the air intake pipe 1501 works, and the smoke enters the air intake pipe 1503 through the collection pipe 10, and finally reaches the detection chamber 15, while the reference chamber 14 is filled with a gas element that does not absorb any infrared energy. The infrared component 16 is turned on. The infrared component 16 can emit infrared rays of different bands by adjustment. Different components can be detected by bands of different frequencies. As time goes by, the content change or content value of the component inside can also be judged. During the detection process, the guide disc 1802 rotates to drive the guide groove 1803 to rotate. The guide groove 18 03 is spiral, which will guide the smoke in the detection chamber 15 to form a cyclone, adjust the smoke concentration, and the gas at the air inlet 1501 moves along the inner wall of the detection chamber 15. At the same time, the cyclone formed can effectively reduce the impact of the smoke on the detection chamber 15 when it enters the detection chamber 15, and reduce the generation of excess energy in the smoke. Then the receiving chamber 17 will organize and convert the electrical signals and transmit them to the circuit substrate 13 through the wire. The circuit substrate 13 will integrate these electrical signals. The smoke detection component 5 will transmit the collected information to the smoke analysis box 1 through the signal access port 4. The smoke analysis box 1 will analyze these electrical signals and display the analyzed data on the display screen 2 for the operator to record. The cleaning component will regularly clean the detection chamber 15. The cleaning component will regularly clean it, using a combination of high air pressure and high vibration to completely remove impurities on the inner wall of the detection chamber 15.
