[0044] Please see Figures 1 to 3 This application provides a novel online exhaust gas monitoring device, which includes:

[0045] Calibration channel 1, full-process calibration tube assembly 2, cabinet housing 3, and monitoring components 4;

[0046] The monitoring component 4 and the full-process calibration tube component 2 are disposed inside the cabinet housing 3;

[0047] The calibration channel 1 is connected to the full-process calibration tube assembly 2 and is used to control the entry and exit of calibration gas;

[0048] The full-process calibration tube assembly 2 is connected to the monitoring assembly 4 and is used to control the gas flow rate of the calibration gas entering the monitoring assembly.

[0049] The components of this embodiment are described in detail below:

[0050] Calibration Channel 1: Located outside the cabinet housing 3, Calibration Channel 1 connects to the full-process calibration tube assembly 2. Its main function is to precisely control the entry and exit of calibration gas. Calibration Channel 1 is equipped with a dedicated gas control device. This device is controlled by externally input data, ensuring that the calibration gas effectively enters and exits Calibration Channel 1 according to predetermined methods and time parameters. This system significantly improves the efficiency and accuracy of calibration work and reduces human error.

[0051] Full-process calibration tube assembly 2: Located inside the cabinet housing 3, the full-process calibration tube assembly 2 connects to the monitoring assembly 4 and the calibration channel 1. Its main function is to precisely control and adjust the flow rate of calibration gas entering the monitoring assembly.

It is designed to sample the calibration gas, collect data from the sampled calibration gas, and analyze and compare the data with the internal gas data.

[0054] In this embodiment, calibration channel 1 controls the calibration gas to enter calibration channel 1, and full-process calibration tube assembly 2 is connected to calibration channel 1. Full-process calibration pipeline 2 controls the calibration gas to enter monitoring component 4 at a certain flow rate. Monitoring component 4 samples, analyzes and measures the calibration gas at a certain flow rate.

[0055] In practical applications, staff outside the cabinet input data to control the calibration channel 1, controlling the flow of calibration gas into it. Once the calibration gas is in the calibration channel 1, staff outside the cabinet input data a second time to control the control device of the full-process calibration tube assembly 2, ensuring the calibration gas enters the monitoring assembly 4 at a stable flow rate. In practice, staff use the monitoring assembly 4 to compare and analyze the calibration gas with the internal gas, adjusting the calibration gas concentration based on the measurement results until the calibration gas meets the predetermined accuracy and stability requirements.

[0056] In this embodiment, by adding a calibration channel 1 and a full-process calibration tube assembly 2 to the existing online exhaust gas detection device, the calibration gas is controlled to enter the device at a certain flow rate, ensuring the operational stability of the online exhaust gas monitoring device and thus improving the accuracy of the detection data.

[0057] In an optional embodiment, the calibration channel 1 includes a calibration gas inlet / outlet channel 11 and a calibration control valve 12;

[0058] The standard gas inlet / outlet channel 11 is connected to the full-process calibration tube assembly 2;

[0059] The calibration control valve 12 is installed on the calibration gas inlet / outlet channel 11.

[0060] This embodiment provides a specific implementation of calibration channel 1, in which calibration channel 1 includes a calibration gas inlet / outlet channel 11 and a calibration control valve 12. By installing the calibration control valve 12 on the calibration gas inlet / outlet channel 11, the entry and exit of calibration gas into and out of the calibration gas inlet / outlet channel 11 can be controlled. In practical applications, operators control the calibration gas inlet / outlet channel 11 by controlling the calibration control valve 12.

[0061] In this embodiment, by installing a calibration control valve 12 on the calibration gas inlet / outlet channel 11, it is ensured that the calibration gas can effectively enter and exit the calibration gas inlet / outlet channel 11 according to predetermined methods and time parameters.

[0066] This embodiment provides an implementation method for a full-process calibration tube assembly 2, which includes a first calibration line 21 and a solenoid valve 22. The calibration gas inlet / outlet channel 11 is connected to the monitoring component 4 via the first calibration line 21. By installing the solenoid valve 22 on the first calibration line 21, the flow rate of calibration gas entering the monitoring component 4 is controlled. In practical applications, the operator controls the first calibration line 21 to deliver the calibration gas from the calibration gas inlet / outlet channel 11 to the monitoring component 4, and effectively controls the flow rate of calibration gas entering the monitoring component 4 by controlling the solenoid valve 22 on the first calibration line 21.

[0067] In this embodiment, the operator controls the solenoid valve 22, which ensures that the gas flow rate received by the monitoring component 4 meets specific calibration requirements during the calibration or verification process, thereby guaranteeing the accuracy and reliability of subsequent measurement or detection results.

[0068] In an optional embodiment, the monitoring component 4 includes a cabinet control panel 41, a sampling platform 42, an analyzer 43, and a sensor 44;

[0073] This embodiment provides an implementation of the monitoring component 4, which includes a cabinet control panel 41, a sampling platform 42, an analyzer 43, and a sensor 44. In practical applications, calibration gas enters the cabinet control panel 41 along the first calibration pipeline 21. The cabinet control panel 41 monitors the status of the incoming calibration gas. The calibration gas then continues along the second calibration pipeline 21 into the sampling platform 42, where it is sampled and extracted. After sampling, the sampling platform 42 delivers the collected gas sample to the analyzer 43 via the third calibration pipeline 24. The analyzer 43 collects data from the gas sample and transmits the processed calibration gas data to the sensor 44 via an electrical connection. The sensor 44 compares and analyzes the calibration gas sample data with internal gas data.

[0074] In this embodiment, the data acquisition and analysis are effectively realized through the connection and data transmission functions of devices such as the cabinet control panel 41, sampling platform 42, analyzer 43 and sensor 44. This provides effective support for adjusting the calibration gas concentration based on the measurement results until the system reaches the predetermined accuracy and stability requirements.

[0075] In an optional embodiment, the sampling platform 42 is provided with a sampling probe 421 and a base 422;

[0076] The sampling probe 421 is mounted on the base 422;

In practical applications, the sampling probe 421 is used to collect the required gas sample, and the base 422 is used to collect the gas sample. After completing the calibration gas collection, the sampling probe 421 transmits the collected calibration gas sample to the third calibration pipeline 24 via the base 422.

[0079] In this embodiment, by setting a sampling probe 421 and a base 422 on the sampling platform 42, gas samples are collected, providing effective technical support for subsequent data collection of calibration gases.

[0080] In an optional embodiment, a heat tracing pipe 25 is installed on the third calibration line 24.

[0081] This embodiment provides an implementation of a heat tracing pipe 25, which is installed on a third calibration pipeline 24. In practical applications, the main function of the heat tracing pipe 25 is to provide continuous and stable temperature control for the third calibration pipeline 24. This function ensures that the calibration gas sample within the third calibration pipeline can be maintained within a suitable temperature range during transmission, effectively preventing condensation caused by changes in ambient temperature. By precisely controlling the temperature, the heat tracing pipe 25 ensures the stability of the physical state of the calibration gas sample, providing a reliable guarantee for gas sample transmission.

[0082] In this embodiment, condensation may cause corrosion or blockage inside the third calibration line 24, affecting the normal operation and lifespan of the equipment. The application of the heat tracing pipe 25 effectively avoids this problem, extends the service life of the third calibration line 24, and thus reduces maintenance costs.

[0083] In an optional embodiment, the rack control panel 41 is provided with a pre-processing control board 411, which is located on the outside of the rack housing 3.

[0084] This embodiment provides an implementation of a rack control panel 41. In this implementation, a preprocessing control board 411 is mounted on the rack control panel 41 and is located on the exterior of the rack housing 3. In practical applications, operators can remotely control and monitor the monitoring component 4 through the preprocessing control board 411. The preprocessing control board 411 can monitor the working status of the monitoring component 4 in real time, including its operating status and fault information. By feeding back the working status to the rack control panel 41, the rack control panel 41 feeds back this working status to the preprocessing control board 411. Operators can quickly understand the current status of the monitoring component 4 by checking the preprocessing control board 411, thus enabling timely responses and actions. Furthermore, the preprocessing control board 411 can receive data input from operators and perform physical control of the monitoring component 4, calibration channel 1, and full-process calibration tube assembly 2.

[0085] In this embodiment, the user inputs data information into the preprocessing control board 411 to physically control the monitoring component 4, calibration channel 1, and full-process calibration tube assembly 2. This reduces direct contact between personnel and the monitoring component 4, calibration channel 1, and full-process calibration tube assembly 2, lowering the safety risks that may arise from improper operation or equipment malfunction. Simultaneously, the operational status monitoring function can promptly detect potential problems and prevent malfunctions, further ensuring the safety of equipment and personnel.

[0086] In an optional embodiment, the pretreatment control board 411 is provided with a temperature controller 412, a calibration adjustment switch 413, and a calibration gas flow regulator 414.

[0090] This embodiment provides an implementation of a pretreatment control board 411, which includes a temperature controller 412, a calibration adjustment switch 413, and a calibration gas flow regulator 414. In practical applications, the temperature controller 412 controls and displays the current temperature, allowing operators to control the temperature of the heating pipe 25 by checking the displayed temperature, thus ensuring the stability of the physical state of the calibration gas sample. Before the calibration gas enters the calibration gas inlet / outlet channel 11, operators can control the calibration control valve 12 by turning the calibration adjustment switch 413, ensuring that the calibration gas effectively enters and exits the calibration gas inlet / outlet channel 11 according to a predetermined method and time. Before the calibration gas enters the monitoring component 4, operators can control the solenoid valve 22 on the first calibration pipeline 21 by adjusting the calibration gas flow regulator 414, thereby controlling the flow rate of the calibration gas into the monitoring component 4. This function ensures that the gas flow rate received by the monitoring component 4 meets specific calibration requirements during calibration or verification, thus guaranteeing the accuracy and reliability of subsequent measurement or detection results.

In practical applications, staff can operate the backflush button 416 to control the backflush port for equipment cleaning, thereby maintaining the equipment in good working condition.

[0093] In an optional embodiment, the cabinet housing 3 is provided with a ventilation section 31, which is connected to the analyzer 43 and is used to discharge the gas inside the analyzer 43.
