Abstract
Description
Technical Field
[0001] The invention belongs to the field of detection equipment, and particularly relates to a continuous emission detection device for atmospheric pollutants. Background Art
[0002] In the glass, ceramic, cement and other manufacturing industries, high-temperature kilns are required for processing operations. During the operation, combustion waste gas will be emitted into the air. The waste gas emitted contains sulfur dioxide (SO2), nitrogen oxides (NOx), carbon monoxide (CO), etc. It is necessary to test whether the content meets the standards. Because once the gas content exceeds the standard, it will seriously endanger environmental health and cause serious environmental pollution.
[0003] Since exhaust gas is emitted continuously, it is not possible to judge whether the exhaust gas emissions meet the standards based solely on the test results of a certain period of time. Instead, the exhaust gas should be tested continuously. The continuous emission monitoring system (CEMS) is a system installed on the chimney or emission pipe that can monitor the concentration of pollutants such as nitrogen oxides. The continuous emission monitoring system usually includes a gas sampling probe, an analyzer and a data recording system. During the detection process, the sampling probe is directly installed inside the chimney, and the flue gas is sampled using the sampling probe, and then the sample is tested by the analyzer.
[0004] However, since the sampling probe is directly located in the flue gas for a long time, particles in the flue gas are easily attached to the sampling probe, causing the air inlet of the sampling probe to be blocked, thereby affecting the detection results. Summary of the Invention
[0005] The purpose of the present invention is to provide a continuous detection device for atmospheric pollutant emissions, which can filter out some particles in the flue gas during the process of flue gas sampling, thereby avoiding particle blockage and causing unsmooth flue gas sampling.
[0006] To achieve the above-mentioned object, the technical solution adopted by the present invention is a continuous detection device for atmospheric pollutant emissions, comprising: a flue gas sampling component, located above the chimney, for collecting and sampling the flue gas flowing out of the chimney;
[0007] a particle sampling component, located below the flue gas sampling component and capable of rotating, for sampling particles in the flue gas;
[0008] The transmission arm is connected to the flue gas sampling component and the particle sampling component respectively, and is used to move the two to the top of the chimney. After moving to the top of the chimney, the flue gas passes through the particle sampling component and the flue gas sampling component in sequence.
[0009] Furthermore, the flue gas sampling component includes: a flue gas collection hood, located above the chimney, for collecting flue gas;
[0010] The smoke flow pipe is connected to the smoke collection hood and is used to provide a flow channel for the collected smoke.
[0011] Furthermore, the particle sampling component includes: a flat hanging plate that is rotatable and has a smoke hole;
[0012] The filter sheet is covered on the flat hanging plate and is used to filter out particles in the flue gas.
[0013] Furthermore, the particle sampling component further comprises: a notch, provided on the flat hanging plate;
[0014] A horizontal lifting shaft is located in the notch and connected to the horizontal lifting plate;
[0015] The adsorption sleeve is arranged on the horizontal hanging shaft and can rotate, and is used for adsorbing particles in the flue gas.
[0016] Furthermore, the particle sampling component further includes: a transmission bar, which is located above the flat hanging plate and extends in an arc shape, and has convex teeth on its lower surface;
[0017] The outer gear ring is fixed to the end of the adsorption sleeve and meshes with the convex teeth on the transmission bar, so that the adsorption sleeve can rotate when performing circular motion.
[0018] Furthermore, the particle sampling component further includes: a sector-shaped flat plate fixed on the transmission bar;
[0019] The scraper is located on the fan-shaped flat plate and extends downward, and is used to remove particles on the adsorption sleeve.
[0020] Furthermore, it also includes: a bearing body, which is hinged to the transmission arm and is used to lock the positions of the smoke sampling component and the particle sampling component.
[0021] Furthermore, the power transmission arm includes: a tilting arm connected to the smoke sampling component and the particle sampling component;
[0022] The horizontal supporting arm is fixedly connected to the tilting supporting arm. When the horizontal supporting arm is in a horizontal state, the tilting supporting arm is in a vertical state.
[0023] Support arm, connected to the flat support arm;
[0024] The transmission disc is fixedly connected to the support arm and is connected to the bearing body. When the transmission disc rotates, the smoke sampling component and the particle sampling component are connected and moved.
[0025] Furthermore, it also includes: a top component connected to the chimney, which is used to position the bearing body.
[0026] Furthermore, the positioning component includes: a guide rail, arranged on the chimney;
[0027] The slide is connected to the guide rail and the bearing body respectively and can slide along the length direction of the guide rail;
[0028] The clamping piece is connected to the bearing body and is used for clamping the chimney.
[0029] Compared with the prior art, the beneficial effect of the present invention is that when the flue gas is sampled, the flue gas passes through the particle sampling component and the flue gas sampling component in sequence. When the flue gas passes through the particle sampling component, some particles in the flue gas are filtered out by the particle sampling component, and then when the flue gas flows to the flue gas sampling component, the particulate matter contained therein will be reduced. When the particulate matter can be completely filtered out, the blockage of the flue gas flow channel on the flue gas sampling component can be avoided. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0041] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.
[0042] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.
[0043] See Figure 1 As shown, a continuous detection device for atmospheric pollutant emissions includes a flue gas sampling component, a particle sampling component and a carrying body 1. The flue gas sampling component and the particle sampling component are both connected to the carrying body 1. A positioning component is also connected to the carrying body 1. The positioning component is connected to the outside of the chimney 2, so that the position of the carrying body 1 is locked. At this time, the carrying body 1 cannot move. A carrying cavity is provided inside the carrying body 1, and a detection analyzer is provided in the carrying cavity (the detection analyzer is a prior art product). Then, the flue gas discharged from the chimney 2 can be sampled through the flue gas sampling component, and the sample is transported to the detection analyzer for detection.
[0044] The positioning components include a clamping member and a slide 3. The slide 3 and the clamping member are both connected to the supporting body 1. The slide 3 is connected to a guide rail 4. The guide rail 4 is installed on the chimney 2. The guide rail 4 extends along the length direction of the chimney 2. The slide 3 and the supporting body 1 can move along the length direction of the guide rail 4, so that the supporting body 1 can be moved from the bottom of the chimney 2 to the top of the chimney 2, and the supporting body 1 located at the top of the chimney 2 can also be moved downward. When the supporting body 1 is at the top position of the chimney 2, the chimney 2 is tightly clamped by the clamping member to achieve the positioning of the supporting body 1. At this time, the supporting body 1 is connected to the chimney 2, which increases the stability of the supporting body 1 while moving the flue gas sampling component and the particle sampling component to the top of the chimney 2. The flue gas discharged from the chimney 2 passes through the particle sampling component and the flue gas sampling component in turn to achieve flue gas sampling;
[0045] See Figure 2 、 Figure 9 and Figure 10 As shown, the above-mentioned flue gas sampling device includes a flue gas collecting hood 501, which can be moved to the top of the chimney 2. The flue gas collecting hood 501 is connected to a flue gas circulation pipe 502. When the flue gas collecting hood 501 is located directly above the chimney 2, the flue gas circulation pipe 502 is located between the chimney 2 and the flue gas collecting hood 501. During the process of the flue gas discharged from the chimney 2 flowing to the flue gas collecting hood 501, the flue gas contacts the outer wall of the flue gas circulation pipe 502. At this time, the heat in the flue gas is transferred to the flue gas circulation pipe 502. The lower end of the flue gas circulation pipe 502 is connected to a flexible pipe. The flexible tube 503 extends into the interior of the supporting body 1 and is connected to the detection analyzer. At the same time, a flue gas drainage component (such as an exhaust pump, etc.) is provided on the detection analyzer to draw the flue gas in the flue gas collection cover 501 into the detection analyzer. During the flow of flue gas in the flue gas circulation pipe 502, the heat in the flue gas is transferred to the flue gas circulation pipe 502. Therefore, during the flow of flue gas in the flue gas circulation pipe 502, the gas will not condense. At this time, the inner wall of the flue gas circulation pipe 502 is relatively dry, which reduces the adhesion of dust particles in the flue gas.
[0046] The upper end of the above-mentioned flue gas circulation pipe 502 is connected to the top of the flue gas collection cover 501. The flue gas circulation pipe 502 includes a vertical section 5021 and a horizontal section 5022. The connection between the lower end of the vertical section 5021 and the horizontal section 5022 is an arc transition. The other end of the horizontal section 5022 is connected to the flexible pipe 503. At this time, the vertical section 5021 is parallel to the central axis of the chimney 2, and the horizontal distance between the vertical section 5021 and the supporting body 1 is relatively large. 1 is also fixed with a tilting arm 601, and a particle sampling component is installed on the tilting arm 601. When the smoke collection cover 501 is located above the chimney 2, the particle sampling component is located between the smoke collection cover 501 and the chimney 2. At this time, the tilting arm 601 is in a vertical state, and the particle sampling component is located above the horizontal section 5022 of the smoke flow pipe 502. That is, the smoke discharged from the chimney 2 first passes through the particle sampling component, and the particles in the smoke are sampled by the particle sampling component.
[0047] See Figure 1 、 Figures 7 to 9 As shown, the particle sampling component includes a rotating sleeve 701 mounted on the tilting arm 601, and a flat hanging plate 702 is provided on the rotating sleeve 701. The flat hanging plate 702 is provided with a plurality of notches 703. The notches 703 extend along the radial direction of the flat hanging plate 702. A horizontally extending flat hanging shaft 704 is provided in each notch 703. There is a large gap between the flat hanging shaft 704 and the notch 703. A rotatable adsorption sleeve 705 is sleeved on the flat hanging shaft 704. The adsorption sleeve 705 can rotate. When the rotating sleeve 701 rotates, it will drive the flat hanging shaft 704 to move in a circular trajectory. At this time, the adsorption sleeve 705 can pass over the chimney 2, and the dust particles in the flue gas are sampled through the adsorption sleeve 705.
[0048] An extension ring 709 is provided at the rear end of the adsorption sleeve 705, and an outer gear ring is fixed on the outer circumferential surface of the extension ring 709. A fixed arm 706 is provided on the flip arm 601. The fixed arm 706 is located above the rotating sleeve 701 and is in a horizontal state. Arc-shaped transmission bars 707 are provided at both ends of the fixed arm 706, of which the one close to the chimney 2 is the outer transmission bar, and the transmission bar 707 located above the supporting body 1 and away from the chimney 2 is the inner transmission bar. The lower surface of the transmission bar 707 is provided with convex teeth, so that the outer gear ring and the transmission bar 707 are engaged, that is, when the rotating sleeve 70 When the rotating sleeve 701 rotates, it can drive the adsorption sleeve 705 to make a circular motion. After the outer gear ring moves to engage with the transmission bar 707, as the rotating sleeve 701 continues to rotate, the adsorption sleeve 705 and the transmission bar 707 move relative to each other. At this time, the outer gear ring will rotate, thereby driving the adsorption sleeve 705 to rotate. When the adsorption sleeve 705 makes a circular motion in the upper area of the chimney 2, the adsorption sleeve 705 can also rotate around its own central axis, that is, the adsorption sleeve 705 can rotate on its own, thereby improving the utilization rate of the adsorption sleeve 705 and allowing the adsorption sleeve 705 to fully contact the particles in the flue gas;
[0049] When the adsorption sleeve 705 passes over the chimney 2, it will move to the top of the carrier body 1. A fan-shaped flat plate 708 is fixed on the inner transmission bar. Several scrapers are fixed on the fan-shaped flat plate 708. The scrapers extend downward and are arranged along the circumferential direction of the fan-shaped flat plate 708. When the rotating sleeve 701 rotates until the adsorption sleeve 705 passes over the chimney 2, the adsorption sleeve 705 can pass under the inner transmission bar. At this time, the adsorption sleeve 705 contacts the lower edge of the scraper, and bristles can be set at the lower edge of the scraper. When the adsorption sleeve 705 moves in a circular trajectory and rotates, the contact between the scraper and the adsorption sleeve 705 can remove the dust particles on the adsorption sleeve 705 and pass through the gap between the adsorption sleeve 705 and the notch 703. A collecting bucket 710 is provided on the supporting body 1, and the collecting bucket 710 is connected to the detection analyzer through a feeding pipe. In this way, the adsorption sleeve 705 does not need to be constantly smoked by the exhaust gas from the chimney 2, avoiding the adhesion of a large amount of tar, oil particle mixture, etc. on its surface, which makes it impossible to sample the flue gas particles.
[0050] The above-mentioned flat hanging plate 702 can be provided with a smoke hole 7021. At this time, a filter plate can be covered on the upper surface of the flat hanging plate 702. The filter plate can filter out some particles in the smoke, thereby reducing the particle content in the smoke entering the smoke collection hood 501 and avoiding a large amount of dust particles adhering to the inner wall of the smoke circulation pipe 502.
[0051] See Figure 1 、 Figure 4 、 Figure 5As shown, since the flue gas sampling component and the particle sampling component in the present technical solution need to be located above the upper port of the chimney 2, the supporting body 1 needs to be positioned at the upper end of the chimney 2. After long-term use, in order to ensure the accuracy of the detection results, the flue gas sampling component and the particle sampling component also need to be maintained. Therefore, in order to facilitate the maintenance of the flue gas sampling component and the particle sampling component, rail grooves 401 are provided on the two side elevations of the guide rail 4, and an open groove 301 is provided on the bottom surface of the slide 3. After the guide rail 4 and the slide 3 are assembled, part of the guide rail 4 is located in the open groove 301 of the slide 3. At this time, a guide wheel group 302 is provided on the side elevation of the slide 3. The guide wheel group 302 is located in the rail groove 401. The guide wheel group 302 is composed of a plurality of guide wheels arranged along the length direction of the slide 3. The setting of the guide wheel group 302 can prevent the slide 3 from separating from the guide rail 4, and has strong stability during the upward movement of the supporting body 1.
[0052] A linear groove 402 is provided on the top surface of the guide rail 4, and the bottom surface of the linear groove 402 has protruding teeth, which are arranged along the length direction of the linear groove 402. A cavity is provided in the carrier body 1, and a driving motor is installed in the cavity of the carrier body 1. A through opening 303 is provided on the slide 3, and the output end of the driving motor is connected to a driving gear. After passing through the through opening 303, the driving gear engages with the protruding teeth on the bottom surface of the linear groove 402. Through the operation of the driving motor, the carrier body 1 can climb upward along the guide rail 4. The driving motor is a radio motor and has a power-off self-locking function. Its operation can be controlled by a remote control, so that the carrier body 1 can be conveniently moved to the top position of the chimney 2.
[0053] See Figure 3 、 Figure 6 、 Figure 7 As shown, the clamping member includes an arm 801 hinged on the supporting body 1, and the arm 801 is two, and the two arm 801 can move simultaneously, that is, they can move in a direction close to each other or in a direction away from each other. The specific moving direction is related to the moving direction and position of the supporting body 1. When the supporting body 1 moves toward the top of the chimney 2 and has approached the top position of the chimney 2, the supporting body 1 continues to climb upward. At this time, the two arm 801 will move in a direction close to each other, and finally both arm 801 will contact the chimney 2. At this time, the two arm 801 hold the chimney 2 tightly, so that the supporting body 1 has a high stability. When it is necessary to move the supporting body 1 downward from the top position of the chimney 2, the output shaft of the driving motor is controlled to rotate in the opposite direction, which drives the supporting body 1 downward and simultaneously moves the two arm 801 in a direction away from each other. At this time, the two arm 801 no longer contact the chimney 2, so that the supporting body 1 can move downward.
[0054] A stopper 403 is provided on the guide rail 4, and the stopper 403 is close to the upper end of the guide rail 4. A jacking rod 304 is connected to the slide 3, and the jacking rod 304 passes through the slide 3. At this time, the jacking rod 304 can move relative to the slide 3, and an elastic reset member 305 is connected between the jacking rod 304 and the slide 3. In the initial state, there is a certain distance between the upper end of the jacking rod 304 and the upper end of the slide 3, and as the supporting body 1 climbs upward, the slide 3 and the jacking rod 304 are driven to move upward until the upper end of the jacking rod 304 is against the stopper 403, and then as the supporting body 1 continues to climb , the blocking seat 403 blocks the further movement of the lifting rod 304. At this time, the lifting rod 304 and the slide 3 move relative to each other, so that the distance between the upper end of the lifting rod 304 and the upper end surface of the slide 3 gradually decreases. As the distance gradually decreases, the two arm rods 801 move in the direction of approaching each other. Finally, when the chimney 2 is tightly held by the two arm rods 801, the supporting body 1 and the slide 3 cannot continue to climb upward. At this time, the driving motor stops working, thereby realizing the positioning of the supporting body 1 and the slide 3, so that the supporting body 1 at the top of the chimney 2 has higher stability and is not easy to fall.
[0055] Specifically, a flat plate is docked at the upper end of the top rod 304, and a traction member 306 is docked at the lower end of the top rod 304. At the same time, an extension channel 307 is provided on the slide 3. The extension channel 307 is parallel to the opening groove 301. The extension channel 307 passes through the slide 3, that is, the extension channel 307 extends from the upper end of the slide 3 to the lower end. The traction member 306 at the lower end of the top rod 304 passes through the extension channel 307. At this time, the upper end of the traction member 306 is located above the slide 3. A guide is provided on the bearing body 1. Wheel 308, the traction component 306 passes over the top of the guide wheel 308 and then extends horizontally, and finally the upper end of the traction component 306 is connected to the arm 801. When the top rod 304 moves axially downward, a downward traction force is applied to the traction component 306, so that the upper end of the traction component 306 applies a pulling force to the arm 801, so that the arm 801 moves toward the direction close to the chimney 2. In this process, the two arms 801 move toward the direction close to each other, and finally the chimney 2 is tightly embraced by the two arms 801.
[0056] The arm 801 is an arc-shaped rod, and a bow-shaped elastic rod 802 is fixed on the inner side of the arm 801. A limit block is provided on the supporting body 1. When the arm 801 moves toward the chimney 2, the elastic rod 802 first contacts the limit block. At this time, the elastic rod 802 first deforms to a certain extent. As the arm 801 continues to move toward the chimney 2, until the arm 801 contacts the chimney 2, the chimney 2 is tightly embraced by the arm 801. When the downward traction force is no longer applied to the traction component 306, the arm 801 moves away from the chimney 2 under the action of the restoring force of the elastic rod 802, thereby facilitating the downward movement of the supporting body 1.
[0057] When the supporting body 1 needs to move downward, the top rod 304 needs to be restored to its initial position, wherein the elastic return member 305 is arranged between the flat plate and the top surface of the slide 3. The elastic return member 305 includes a spring that generates a restoring force after compression. During the upward movement of the supporting body 1, the elastic return member 305 is compressed, and then the arm 801 is driven to move toward the chimney 2. When the output shaft of the control drive motor rotates in the opposite direction, the top rod 304 is restored to its initial position under the action of the restoring force of the elastic return member 305. That is, at this time, the distance between the upper end of the top rod 304 and the top end of the slide 3 gradually increases. At this time, the traction component 306 will not apply a pulling force to the arm 801, so under the action of the elastic rod 802, the arm 801 can be moved away from the chimney 2, and finally the arm 801 is separated from the chimney 2.
[0058] The traction component 306 is a stainless steel traction rope, which has high corrosion resistance and high temperature resistance, and can ensure that the traction force is continuously applied to the arm 801.
[0059] See Figures 1 to 3 and Figure 10 As shown, after the supporting body 1 is moved to the top position of the chimney 2, it is necessary to control the flue gas sampling component and the particle sampling component to be located above the chimney 2. After the flue gas in the chimney 2 is discharged, the flue gas can pass through the particle sampling component and the flue gas sampling component in sequence, thereby sampling the flue gas. The flue gas sampling component and the particle sampling component cannot hinder the upward climbing of the supporting body 1 at the initial stage, so the flue gas sampling component is movably connected to the supporting body 1. When the supporting body 1 climbs upward, the flue gas sampling component and the particle sampling component are located on the side of the supporting body 1. When the supporting body 1 reaches the top of the chimney 2 and the arm 801 moves toward the chimney 2, the flue gas sampling component and the particle sampling component are moved. When the arm 801 hugs the chimney 2, the flue gas sampling device can be located above the chimney 2. At this time, the flue gas sampling device collects and samples the flue gas discharged from the chimney 2.
[0060] The smoke sampling device in the present application can be moved in the lateral direction of the carrier body 1. In order to control its movement, a flat support arm 602 is docked at the lower end of the flip arm 601, and a 90° angle is formed between the flat support arm 602 and the flip arm 601. When the flip arm 601 is in a vertical state, the flat support arm 602 is in a horizontal state. The free end of the flat support arm 602 is docked with a support arm 603, and the support arm 603 is parallel to the flip arm 601. A transmission disk 604 is fixed to the lower end of the support arm 603. At this time, a transmission arm is formed by the flat support arm 602, the support arm 603 and the transmission disk 604. The transmission arm can control the smoke sampling component and the particle sampling component to move in an arc trajectory. A lateral flat port is provided on the carrier body 1, and a central axis is fixed at the center position of the transmission disk 604. The central axis is located in the lateral flat port. 04 is provided with a crown gear, which is coaxially arranged with the transmission disk 604. At the same time, a connecting rod 803 is fixed at the end of the arm 801, and a positioning support is provided on the side of the supporting body 1. The connecting rod 803 is vertically penetrated by the positioning support, at this time, a hinge is formed between the arm 801 and the supporting body 1, and a driving gear 804 is connected to the lower end of the connecting rod 803, and the driving gear 804 is engaged with the crown gear. When the arm 801 moves toward the chimney 2, the transmission disk 604 is driven to rotate through the connecting rod 803, and the support arm 603 is swung upward. At this time, the flue gas sampling device is driven to move in an arc trajectory, so that the flue gas sampling component can move to the flue gas collection cover 501 above the chimney 2. In this way, when the supporting body 1 climbs upward smoothly, the flue gas sampling device will not hinder the climbing of the supporting body 1 during this process.
[0061] In addition, a stepper motor 711 is provided on the flat support arm 602 in the present application, and the output shaft of the stepper motor 711 is parallel to the tilting arm 601. A small gear ring is fixed to the lower end of the rotating sleeve 701, and a working gear is fixed to the output shaft of the stepper motor 711. The working gear is engaged with the small gear ring at the lower end of the rotating sleeve 701. At this time, the rotation of the rotating sleeve 701 can be controlled by the stepper motor 711, so that the adsorption sleeve 705 can perform circular motion, and after passing over the chimney 2, it can adsorb dust particles in the flue gas.
[0062] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate, and the components shown as units may or may not be physical units, i.e., they may be located in one location or distributed across multiple network units.
