DETAILED DESCRIPTION

[0022] The utility model will be described below with specific embodiments, but is not limited to the utility model.

[0023] Example one

[0024] As Figures 1-5 shown in the embodiment, a coal quality particle active carbon denitration value measuring device is provided, which is installed on the smoke pipe 1. The measuring device includes a measuring instrument 4 for monitoring the denitration value of coal quality particle active carbon. The measuring instrument 4 can extend into the interior of the smoke pipe 1, and its main function is to monitor the denitration value of coal quality particle active carbon. The denitration value refers to the ability of active carbon to reduce the content of nitrogen oxides in flue gas. The measuring instrument 4 can extend into the interior of the smoke pipe 1 to accurately monitor.

[0025] The interior of the smoke pipe 1 is provided with a flue 8, and the sidewall of the smoke pipe 1 is provided with a window 2. The interior of the window 2 is provided with a support plate 3 that can extend into the interior of the flue 8. The measuring instrument 4 is fixedly installed on the support plate 3. The smoke pipe 1 is a pipeline for discharging flue gas, and the interior of the smoke pipe 1 is designed with a flue 8 for guiding the flow of flue gas. The window 2 is used to allow a part of the measuring device to extend into the interior of the flue 8 for monitoring. The support plate 3 provides a stable platform for fixedly installing the measuring instrument 4. The measuring instrument 4 is a device for monitoring the denitration value of coal quality particle active carbon, and is fixedly installed on the support plate 3. In this way, the measuring instrument 4 can extend into the interior of the flue 8 through the window 2 to monitor the content of nitrogen oxides in flue gas.

[0026] The measuring instrument 4 is provided with a smoke inlet 43 and a smoke outlet 44. When the support plate 3 extends to the interior of the flue 8, the flow delay can enter the interior of the measuring instrument 4 from the smoke inlet 43 and be discharged from the smoke outlet 44. The measuring instrument 4 is designed with two openings, the smoke inlet 43 and the smoke outlet 44. When the support plate 3 (on which the measuring instrument 4 is installed) extends into the interior of the flue 8, the smoke flowing in the flue 8 can enter the interior through the smoke inlet 43 of the measuring instrument 4. Inside the measuring instrument 4, there are some devices for monitoring or processing the smoke (such as sensors, filters, etc., which are not the problems to be solved by the present invention and are existing technologies, so they are not specifically explained in the present invention). Then, the processed or monitored smoke will be discharged from the smoke outlet 44 of the measuring instrument 4 and continue to flow along the flue 8.

[0027] Example 2

[0028] like Figures 1-5 As shown, based on the first embodiment, this embodiment provides a connection method for the support plate 3, which is as follows:

[0029] A mounting bracket 7 is fixed to the smoke pipe 1. The support plate 3 is connected to the mounting bracket 7 via a connecting rod 6. A drive device is installed inside the mounting bracket 7. This drive device, via the connecting rod 6, drives the support plate 3 into the flue 8. When entering the flue 8, the support plate 3 is positioned at an angle to the flow direction of the flue 8. The measuring instrument 4 is mounted on the side of the support plate 3 near the smoke inlet. The mounting bracket 7 serves as a support point for the subsequent installation and fixation of the connecting rod 6 and support plate 3. The support plate 3 (on which the measuring instrument 4 is mounted) is not directly fixed to the smoke pipe 1, but is connected to the mounting bracket 7 via the connecting rod 6. This allows the support plate 3 to move under the action of the drive device. Inside the mounting bracket 7, a drive device (which can be a motor, cylinder, etc.) is installed. This drive device provides power, driving the support plate 3 through the connecting rod 6 for telescopic movement. When the drive device is activated, it pushes the support plate 3 into or out of the flue 8 via the connecting rod 6. This allows the measuring instrument 4 to be placed at different locations within the flue 8 for monitoring as needed. When support plate 3 extends into flue 8, it is not completely parallel to the flue gas flow direction, but rather arranged at a certain angle. This arrangement is likely intended to optimize the flue gas flow path and improve monitoring accuracy by converging the flue gas and allowing it to more easily enter the measuring instrument 4. The measuring instrument 4 is mounted on the side of support plate 3 near the smoke inlet. This means that when support plate 3 extends into flue 8, the measuring instrument 4 is the first to come into contact with the flowing flue gas, allowing for monitoring.

[0030] The connecting rod 6 is shaped like an arc plate. An arc-shaped slot 701 is provided inside the fixed frame 7 to match the arc plate. One end of the arc plate extends into the interior of the arc slot and can slide within the arc slot 701. A drive gear 9 is rotatably mounted inside the fixed frame 7, and the drive gear 9 engages with the teeth provided on the connecting rod 6. The connecting rod 6 is not linear, but is designed in the shape of an arc plate. This design may be to match the shape of the cigarette pipe 1 or to achieve a specific motion trajectory. Inside the fixed frame 7, there is an arc-shaped slot 701 that matches the shape of the arc plate. The function of this slot is to provide a stable sliding track for the arc plate, ensuring that it does not deviate from the predetermined path during movement. One end of the arc plate is inserted into the arc slot 701 and can slide within the slot. A motor is fixed inside the fixed frame 7 to drive the drive gear 9 to rotate.

[0031] Example 3

[0032] like Figures 1-5 As shown, based on the first and second embodiments, this embodiment provides an installation method of the measuring instrument 4, which is as follows:

[0033] A baffle 5 is fixed inside the window 2. The baffle 5 is provided with a through hole, and the connecting rod 6 passes through the through hole. The baffle 5 can play a sealing role. When the support plate 3 is in the open state, the smoke cannot be discharged from the window 2. Even if the smoke pressure inside the flue 8 is high, it will not leak out through the window 2.

[0034] When the support plate 3 is closed and mounted on the window 2, a clearance space is created between the support plate 3 and the baffle 5. The measuring instrument 4 is installed within the clearance space. When the support plate 3 is closed, the measuring instrument 4 is securely enclosed, neither interfering with the normal operation of the flue 8 nor being disturbed by the external environment. At the same time, when measurements are required, the support plate 3 can be opened, allowing the measuring instrument 4 to extend into the flue 8 for monitoring, while the baffle 5 seals the window 2 to prevent smoke leakage.

[0035] The measuring instrument 4 comprises a base frame 41 and a cover 42. The cover 42 is semi-cylindrical and contains a space for mounting a measuring tube 45. A smoke inlet 43 and a smoke outlet 44 are located at the end and rear of the cover 42, respectively. The smoke inlet 43 is used to introduce the smoke to be monitored, while the smoke outlet 44 is used to discharge the smoke that has been processed by the measuring tube 45. This design ensures that smoke can pass smoothly through the measuring instrument 4, while facilitating both monitoring and processing of the smoke.

[0036] There is space around the measuring tube 45 and between the base frame 41 and the cover 42. This space is used for the smoke to pass through, ensuring that the smoke can surround the outside of the measuring tube 45.

[0037] Working principle:

[0038] The measuring device is installed on the flue 1 through the fixing frame 7, the support plate 3 is connected with the fixing frame 7 through the connecting rod 6, and the extension and retraction movement of the support plate 3 is controlled by the driving device (such as a motor). When the support plate 3 extends into the inside of the flue 8, it is arranged at an angle with the flow direction of the flue 8, which optimizes the smoke flow path.

[0039] The measuring instrument 4 is fixedly installed on the support plate 3, when the support plate 3 extends into the inside of the flue 8, the flue gas enters the inside of the measuring instrument 4 through the smoke inlet 43 of the measuring instrument 4. The inside of the measuring instrument 4 is provided with a device for monitoring or processing flue gas, which monitors the content of nitrogen oxides in the flue gas. After the monitoring is completed, the flue gas is discharged from the smoke outlet 44 of the measuring instrument 4 and continues to flow along the flue 8.

[0040] The inside of the window 2 is provided with the baffle 5, when the support plate 3 is closed and installed on the window 2, the space is formed between the baffle 5 and the support plate 3, and the measuring instrument 4 is installed in the space. The baffle 5 plays a sealing role to prevent the flue gas from leaking from the window 2.

[0041] The extension and retraction of the support plate 3 is controlled by the driving device, so that the measuring instrument 4 can extend into or withdraw from the inside of the flue 8 as needed for monitoring. The modular design of the measuring instrument 4 facilitates maintenance and replacement.

[0042] Finally, it should be pointed out that the above embodiments are only used to illustrate but not to limit the technical solutions of the present application. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present application can still be modified or replaced equivalently without departing from the spirit and scope of the present application. Any modification or partial replacement should be covered in the scope of the claims of the present application.
