Description

Technical Field

[0001] The present invention relates to the technical field of air monitoring, and in particular to an online air quality monitoring device for environmental protection projects. Background Art

[0002] In the actual monitoring work of environmental protection projects, the emission pollution detection of exhaust gas particulate matter to the air is a common air quality detection item. The particulate matter content of the emitted air is directly related to the air quality. When conducting smoke and exhaust gas quality detection, it is necessary to ensure that the wind pressure speed remains consistent. The chimney outlet is easily disturbed by external wind direction, air pressure and other factors, forming vortexes or sudden changes in air flow cross-sections. When the current environmental protection project air quality online monitoring device is monitoring, the chimney is affected by the environment and exhaust speed. Its exhaust is not convenient for monitoring under the premise of maintaining a consistent exhaust wind speed. Multiple monitoring data deviations are large, affecting data accuracy. At the same time, the monitoring filter is prone to forgetting to clean, which is not convenient for automatic control pre-cleaning to ensure consistent monitoring benchmarks. Filters clogged with impurities will also affect monitoring accuracy. At the same time, traditional cleaning methods are prone to dust backflow, which causes blockage again, affecting data accuracy, and it is not convenient to automatically perform air detection after dehumidification, affecting the life of the filter and reducing data accuracy.

This structure can realize automatic control, which can ensure the accuracy of gas impurity detection. At the same time, this structure adopts the lifting dehumidification member 2, which does not affect the chimney flue gas emission efficiency and does not cause obstruction while performing detection work. When the smoke is collected, the smoke can be promoted to converge in the filter cartridge 704 for detection, shortening the monitoring time, and avoiding the problem of incomplete smoke detection range in the traditional monitoring method of inserting a test structure into the inner wall of the chimney. The lifting hydraulic cylinder 103 is controlled to drive the lifting cover 201 to descend. At this time, the lifting cover 201 descends and fits the mounting ring 101. At this time, the lifting cover 201 can move down to squeeze the circulation slide shaft 301, driving the closing cover 302 to move down, and no longer fit into the circulation hole 1011 for sealing. At this time, the cold water in the circulation hole 1011 can flow into the connecting hole 202 for cooling water supply.

[0036] Among them, the monitoring control component 4 includes: a monitoring installation shell 401 and a power ring 402, the monitoring installation shell 401 is threadedly connected to the lifting cover 201; the power ring 402 is embedded in the inner side of the monitoring installation shell 401; the exhaust control component 5 includes: a guide cover 501, an exhaust hole 5011, a flow control electric push rod 502 and a closing column 503, the guide cover 501 is fixedly installed at the bottom of the lifting cover 201; a gap is set between the outer side of the guide cover 501 and the inner side of the lifting cover 201; a circle of exhaust holes 5011 is opened on the outer side of the guide cover 501; the flow control electric push rod 502 is fixedly installed at the bottom of the guide cover 501 through a bracket; the flow control electric push rod 502 The output shaft is fixedly mounted with a closing column 503; the closing column 503 is slidably plugged into the guide cover 501; the closing column 503 is used to block the exhaust hole 5011; the lifting connection member 6 includes a lifting shell 601, an exhaust pipe 6011, a conductive ring 6012, an air intake pipe 602, a solenoid valve 603 and an extrusion spring 604, and the lifting shell 601 is slidably sleeved on the monitoring installation shell 401; the exhaust pipe 6011 is fixedly mounted on the side of the lifting shell 601, and the exhaust pipe 6011 passes through the monitoring installation shell 401; the air intake pipe 602 is fixedly mounted on the side of the lifting shell 601, and the air intake pipe 602 passes through the monitoring installation shell 401; the air intake pipe 602 02 is equipped with a solenoid valve 603; the air intake pipe 602 is connected to a pressure tank; an extrusion spring 604 is fixedly installed on the top of the lifting shell 601, and the extrusion spring 604 is located inside the monitoring installation shell 401; a conductive ring 6012 is sleeved on the outside of the lifting shell 601, and the conductive ring 6012 is attached to the electrical ring 402. The lifting connector 6 can be used to cooperate with the monitoring control component 4 to detect the exhaust speed during each air impurity detection, ensuring that the exhaust speed is relatively consistent, which can improve the accuracy of the result comparison and is more convenient for long-term monitoring. The air intake speed can be adjusted in conjunction with the exhaust control component 5, and the structure control is simple, eliminating the problem of exhaust speed. To solve the problem of large data deviation caused by different degrees, this structure can use the conductive ring 6012, the power ring 402 and the pressure sensor 703 in series to ensure that the particle detection work can be carried out normally only when the exhaust speed is the same, to prevent misoperation of the detection and recording data. When the lifting cover 201 descends and closes the mounting ring 101, the air pressure is discharged into the lifting shell 601 from the exhaust hole 5011. At this time, under the action of the air pressure, the lifting shell 601 can move, and the closing column 503 is driven to rise and fall by the flow-control electric push rod 502 to adjust the blocking of the exhaust hole 5011. The larger the blocked area of the exhaust hole 5011, the worse the fluidity, which can reduce the exhaust speed.

[0037] Example 2, on the basis of Example 1, the lifting connection member 6 also includes: a stop ring 605, a blocking column 606 and a closed tension spring 607, the end of the exhaust pipe 6011 is fixedly sleeved with a stop ring 605, and the inner side of the stop ring 605 is a slope structure; the exhaust pipe 6011 is sleeved with a blocking column 606, and a gap is provided between the outer periphery of the blocking column 606 and the inner wall of the exhaust pipe 6011; the end of the closed tension spring 607 is fixedly installed on the inside of the exhaust pipe 6011; the other end of the closed tension spring 607 is fixedly installed with a blocking column 606; the blocking column 606 is used to close the stop ring 605; the particle monitoring component 7 includes a monitoring installation cylinder 701, a sliding column 702, a pressure sensor 703 and a filter cylinder 704, which can adopt HZC-H 1 type pressure sensor 703, and an external matching display is connected to the ground for online data display. The monitoring installation tube 701 is fixedly installed on the inner side of the lifting shell 601; a sliding column 702 is slidably installed inside the monitoring installation tube 701, and a spring is connected between the sliding column 702 and the monitoring installation tube 701; a pressure sensor 703 is fixedly installed on the bottom of the sliding column 702; a filter cartridge 704 is slidably installed inside the lifting shell 601, and the end of the pressure sensor 703 is attached to the filter cartridge 704; a filter mesh hole is provided inside the filter cartridge 704; the conductive ring 6012, the power ring 402 and the pressure sensor 703 are connected in series with a power supply; the backflush control component 8 includes: a power post 801, a flashlight 802 and a power block 803, the power post 801 is fixedly installed on the bottom of the lifting cover 201; the flashlight 802 is sleeved on the outside of the power post 801; the power block 803 is fixedly installed on the side of the lifting hydraulic cylinder 103 on the same side; the power post 801 is sleeved in the power block 803;The flashlight 802, the power block 803 and the solenoid valve 603 are connected in series with the power supply, and the particle monitoring component 7 can perform accurate air particulate content detection in real time. The backflush control component 8 can be used to automatically control the backflush of the filter cartridge 704 before the staff needs to perform impurity quality detection, so as to keep the baseline of the filter cartridge 704 consistent each time the air quality is monitored, and at the same time prevent the staff from forgetting the backflush operation, and can realize the control to start the backflush before the detection work. At the same time, the backflush control component 8 is used in conjunction with the guide cover 501, which can realize automatic guidance of dust discharge during the backflush work, and can prevent dust from being directly discharged into the chimney and then discharged again, affecting the particle detection accuracy. At the same time, it also prevents the backflush air pressure from being directly blown into the chimney and affecting parameters such as the chimney exhaust rate, affecting the subsequent detection accuracy. This structure is simple to control and can automatically connect to power without manual operation. The use of a lifting connector 6 prevents pressure release during back-blowing exhaust without affecting normal air pressure circulation, making the structure more reasonable. When the lifting cover 201 drives the power connection column 801 downward, the power connection column 802 will first contact the power connection block 803. At this time, the lifting cover 201 has not yet been attached to the mounting ring 101. At this time, the solenoid valve 603 can be energized to open, releasing air pressure. Under the action of air pressure, the mesh on the filter cartridge 704 can be back-blown. At this time, the particles blown out of the previous filter can be discharged from the exhaust port 5011, guided between the guide cover 501 and the inner side of the lifting cover 201, and directly discharged out of the chimney, preventing impurities from being back-blown into the chimney. The pressure is detected in real time by the pressure sensor 703, and the data can be viewed on an external display.

[0038] The working principle of this embodiment is: the mounting ring 101 is pre-buried at the top of the chimney. When smoke detection is required, the lifting hydraulic cylinder 103 is controlled to drive the lifting cover 201 to descend. The lifting cover 201 descends and fits the mounting ring 101. At this time, the lifting cover 201 can move down to squeeze the circulation slide shaft 301, driving the closing cover 302 to move down and no longer fit into the circulation hole 1011 for sealing. At this time, the cold water in the circulation hole 1011 can flow into the connecting hole 202, fill the lifting cover 201, and be discharged from the drain pipe 203 for circulation. During the process, the water pump external to the water inlet pipe 102 can supply water in real time, ensuring that cooling and water supply can be automatically performed during gas detection. At the same time, when the detection is completed and the lifting cover 201 is lifted, the circulation slide shaft 301 is released, and the closing cover 302 is squeezed by the spring. , and under the control of water pressure, it can move up to block the closed flow hole 1011. When the lifting cover 201 descends to close the mounting ring 101, the air pressure is discharged from the exhaust hole 5011 into the lifting shell 601. At this time, under the action of air pressure, the lifting shell 601 can move, and the closed column 503 is driven to rise and fall by the flow-control electric push rod 502 to adjust the blocking of the exhaust hole 5011. The larger the blocked area of the exhaust hole 5011, the worse the flowability, which can reduce the exhaust speed. Under the squeezing of the squeezing spring 604, the lifting shell 601 drives the conductive ring 6012 to descend. In this way, the position of the conductive ring 6012 can be adjusted to fit the connecting ring 402 to ensure that the exhaust pressure and speed are consistent. At this time, the conductive ring 6012 is connected to the connecting ring 402, and the pressure sensor 703 can be energized. During the pressure detection work, when the lifting cover 201 is controlled to descend, the lifting cover 201 drives the power pole 801 to descend, and the power pole 802 will first contact the power block 803. At this time, the lifting cover 201 has not yet fitted the mounting ring 101. At this time, the solenoid valve 603 can be energized to open and release the air pressure. Under the action of the air pressure, the mesh on the filter cartridge 704 can be back-blown. At this time, the particles blown out last time can be discharged from the exhaust hole 5011, guided between the guide cover 501 and the inner side of the lifting cover 201, and directly discharged outside the chimney to avoid impurities being blown back into the chimney. When the filter cartridge 704 is filtering normally, the air pressure of the chimney itself is relatively small, and the closed tension spring 607 can pull the blocking column 606 to maintain a tight connection with the stop ring 605. The distance is maintained and does not affect the exhaust. On the contrary, after the solenoid valve 603 is opened, the high-pressure gas is quickly released. At this time, the air pressure increases instantly, and the sealing column 606 can stretch the closed tension spring 607 and directly fit the closed stop ring 605. As the lifting cover 201 continues to descend, the flashlight 802 no longer fits the contact block 803. At this time, the solenoid valve 603 is closed and the power is cut off, and the air intake is stopped. At this time, the gas discharged from the chimney can be filtered and isolated through the mesh on the filter cartridge 704. At this time, the permeability of the filter cartridge 704 becomes worse, and the force pushed upward by the air pressure increases. The pressure is detected in real time by the pressure sensor 703, and the data is observed through an external display. The pressure sensor 703 detection data parameters can be monitored for reference within the same time.
