Description

Technical Field

[0002] CEMS (Continuous Emission Monitoring System) is a device that continuously monitors the concentration and total amount of gaseous pollutants and particulate matter emitted by air pollution sources and transmits the information to the competent authorities in real time. The CEMS system is widely used in emission supervision of fixed pollution sources, such as boilers, industrial furnaces, incinerators, etc. It tracks and measures the pollutant concentration in the emitted flue gas in real time, and uploads the data to the local environmental management department, providing a scientific basis for environmental protection supervision.

[0065] In one embodiment, a cross connection portion 71 is disposed at one end of the threaded rod 304 away from the extrusion portion 306 , and an outer side wall of the cross connection portion 71 is slidably connected to an inner side wall of the central support plate 102 .

[0066] The cross connection part 71 is driven to move by the threaded rod 304 , and the moving cross connection part 71 slides in the central support plate 102 to prevent the threaded rod 304 from rotating synchronously with the first nut 305 .

[0067] In one embodiment, four sliders 72 are symmetrically fixedly connected to the top of the lower bracket 103, two slide grooves 75 are provided at the bottom of the central support plate 102, the outer walls of the four sliders 72 are slidingly connected to the inner walls of the two slide grooves 75 respectively, the inner wall of the lower bracket 103 is symmetrically slidingly connected to four screws 73, the upper surface of the central support plate 102 is symmetrically fixedly connected to four second nuts 74, one ends of the four screws 73 pass through the lower bracket 103, the sliders 72 and the inner wall of the central support plate 102 in sequence and are threadedly connected to the inner wall of the second nut 74, and the other ends of the four screws 73 are fixedly connected to knobs 76.

[0068] The slider 72 is driven into the slide groove 75 by moving the lower bracket 103, and then the slider 72 is driven to slide in the slide groove 75 by moving the lower bracket 103 horizontally. When the movement of the slider 72 is restricted by the slide groove 75, the screw rod 73 is driven to penetrate the lower bracket 103, the slider 72 and the center support plate 102 by moving the knob 76, and the screw rod 73 is threadedly connected with the second nut 74 by turning the knob 76, so that the lower bracket 103 is installed and fixed as a whole on the bottom of the center support plate 102.

[0069] When the present invention is working: firstly, the installation position of the monitoring device is determined according to actual needs, and pre-drilling is performed outside the chimney body 101 according to the determined installation position.

[0070] When the monitoring device needs to be installed, the central support plate 102 is first moved to drive the first plug-in portion 301 to be inserted into the pre-punched hole, and then the first nut 305 is rotated to drive the threaded rod 304 to move using the thread. The moving threaded rod 304 drives the cross connection portion 71 and the extrusion portion 306 to move. The moving cross connection portion 71 slides in the central support plate 102 to prevent the threaded rod 304 from rotating synchronously with the first nut 305. The moving extrusion portion 306 slides into the connecting sleeve 302 to push the limit block 307 to move, so as to partially remove the limit block 307 from the connecting sleeve. At the top of 302, when the movement of the extrusion part 306 is blocked, the moving threaded rod 304 cooperates with the extrusion part 306 to drive the connecting sleeve 302 to move as a whole, and the moving connecting sleeve 302 drives the spring 303 and the limit block 307 to move. The moving spring 303 is compressed, and the moving limit block 307 contacts the inner wall of the chimney body 101 to limit the connecting sleeve 302, and then the first nut 305 is continued to be rotated to make one side of the central support plate 102 fit and squeeze the outer wall of the chimney body 101 to complete the preliminary fixing operation of the central support plate 102. Then, the distance between the side support rods 401 is adjusted by rotating the internal threaded sleeve 403 using the thread, so that the overall length of the side support rods 401 and the internal threaded sleeve 403 can be adjusted according to actual needs, and then the fixing block 402 is installed and fixed on the surface of the chimney body 101 using expansion bolts, so that the side support rods 401 and the internal threaded sleeve 403 can be used to provide support for the bottom of one side of the central support plate 102, thereby increasing the overall stability of the central support plate 102.

[0071] When the center support plate 102 is fixed, the central control communication mechanism 6 and the integrated detection mechanism 5 are driven to move as a whole by moving the lower bracket 103, and the slider 72 is driven to slide into the slide groove 75, and then the slider 72 is driven to slide in the slide groove 75 by moving the lower bracket 103 horizontally, so that the slide groove 75 cooperates with the slider 72 to provide supporting tension for the lower bracket 103, and the lower bracket 103 is used to drive the integrated detection mechanism 5 to be inserted into the interior of the chimney body 101. When the movement of the slider 72 is restricted by the slide groove 75, the screw rod 73 is driven to penetrate the lower bracket 103, the slider 72 and the center support plate 102 by moving the knob 76, and the screw rod 73 is threadedly connected with the second nut 74 by turning the knob 76, so that the lower bracket 103 is installed and fixed as a whole on the bottom of the center support plate 102, thereby completing the overall installation operation of the monitoring equipment.

[0072] When the monitoring equipment is put into use, the arc-shaped curved fan blades 202 drive the central shaft 201 to rotate under the action of wind force, and the rotating central shaft 201 drives the input shaft of the wind turbine 204 to rotate, so as to provide mechanical power for the wind turbine 204, and then the mechanical energy is converted into electrical energy through the wind turbine 204, and the electrical energy is transmitted to the battery 604 for storage in conjunction with the inverter, so as to power the entire equipment.

[0073] When it is necessary to monitor the flue gas discharged from the chimney body 101, the temperature and humidity, SO2, NOx gas content, solid particulate content and flow rate and other data in the flue gas in the chimney body 101 are detected through the integrated probe 503, and the detected data are fed back to the control terminal 603, and then the data is pre-stored through the control terminal 603, and the detected data is sent to the main system in conjunction with the communication module 605 for CEMS online monitoring. When the monitored data exceeds the threshold, the warning light 606 is started by the control terminal 603 using a relay, and the working warning light 606 issues a light warning, and the ventilation hood 502 is set to extend the time the flue gas stays inside it, so that the integrated probe 503 can accurately detect the flue gas.

[0074] In order to reduce the overall energy consumption of the monitoring equipment and ensure that the power generation of the power generation mechanism 2 can meet the overall needs of the equipment, a timed start program can be entered into the control terminal 603 so that the integrated probe 503 can be controlled by the control terminal 603 to monitor the flue gas emitted from the chimney body 101 at regular intervals.

[0075] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
