The thermal power plant uses a power generation method that converts the chemical energy of coal, natural gas, oil, biomass, etc. into electrical energy, resulting in serious carbon emission problems, and it is necessary to accurately monitor the carbon emissions of thermal power plants in real time.

[0003] In the prior art, when monitoring the carbon emissions of thermal power plants, the hot waste gas emitted after combustion is usually introduced into the monitor for measurement and analysis. Due to the high temperature of the hot waste gas, it will greatly reduce the monitoring accuracy and the service life of the device. The particulate matter contained in the waste gas is likely to cause blockage of the air filtration device and requires frequent cleaning, resulting in high maintenance costs.

[0035] The working process of the present utility model is as follows:

[0036] When it is necessary to use this device to monitor the carbon emissions of the hot exhaust gas in a thermal power plant, an instruction can be issued in the main control room of the power plant. The WI-FI antenna 12 will send the received instruction to the main control module 32. Subsequently, the main control module 32 controls the micro-fan 26 to start, introducing the hot exhaust gas from the smoke exhaust duct of the thermal power plant into the hot exhaust gas intake channel 10. The hot exhaust gas filters the particulate matter in the gas using the air filter plate 9, and then enters the double-spiral elastic tube bundle heat exchanger body 33, flowing out after passing through the tube-side fluid inlet pipe 37, the outer spiral elastic tube bundle 43, the inner spiral elastic tube bundle 44, and the tube-side fluid outlet pipe 40. During this period, heat is transferred to the circulating cooling water to reduce the gas temperature. Subsequently, the cooled exhaust gas enters the multi-gas monitoring mechanism. The temperature acquisition module 28, the CO2 acquisition module 27, the CH4 acquisition module 29, and the N2O acquisition module 30 monitor the exhaust gas temperature and the contents of CO2, CH4, and N2O gases in real time, and complete data processing in the main control module 32 to generate carbon emission data and carbon emission warning information. The data is transmitted back to the main control room of the thermal power plant in real time through the WI-FI module 31 and the WI-FI antenna 12, and the relevant parameters are also displayed on the display screen 8 in real time. Once the carbon emission exceeds the standard, the device will send a warning to the relevant personnel through the warning light 14, the buzzer 13, the WI-FI module 31, and the WI-FI antenna 12. The exhaust gas that has completed the monitoring is discharged through the hot exhaust gas exhaust channel 16. When necessary, the operation of this device can also be manually controlled through the control panel 7. When the device is running, the circulating cooling mechanism keeps running. The water pump 20 pumps out the cooling water in the cooling water tank 19 and injects it into the double-spiral elastic tube bundle heat exchanger body 33, flowing out after passing through the shell-side fluid inlet 41, the baffle plate 45, and the shell-side fluid outlet 42. During this period, the cooling water absorbs the heat of the hot exhaust gas and heats up. The setting of the hollow tube 46 can prevent the cooling water from flowing through the area without tube bundles, improving the heat exchange efficiency. The liquid flow meter 24 monitors the cooling water flow in real time. Subsequently, the heated cooling water enters the plate-fin heat exchanger 18, flowing out after passing through the hot side inlet 47, the inlet head 48, the hot fluid flow channel 51, the outlet head 50, and the hot side outlet 49. During this period, the heat is transferred to the air through the fins 52. The radiator fan body 17 keeps running, sucking in air through the top radiator air intake grille 11 and the side radiator air intake grille 4, flowing through the fins 52, and then discharging it from the radiator exhaust grille 2, dissipating the heat of the cooling water into the environment to cool down the cooling water. The cooled cooling water flows back to the cooling water tank 19. During the operation of the circulating cooling mechanism, the main control module 32 adjusts the opening degree of the liquid flow control solenoid valve 21 and the rotation speed of the water pump 20 in real time according to the temperature information monitored by the temperature acquisition module 28 to adjust the cooling water flow, thereby adjusting the hot exhaust gas temperature, enabling the data acquisition module to always operate at the optimal working temperature, improving the monitoring accuracy, extending the device life, reducing costs. After the device has been running for a period of time, the air filter plate 9 is blocked due to the accumulation of particulate matter, resulting in a decrease in the hot exhaust gas intake flow rate, affecting the monitoring. Therefore,The main control module 32 regularly starts the compressed air backwashing mechanism to clean the particulate matter on the air filter plate 9. The main control module 32 first stops the operation of the device, then closes the solenoid valve 25 of the monitoring module, opens the solenoid valve 22 of the gas cylinder, releases the compressed air in the compressed air cylinder 23. After the cleaning is completed, the solenoid valve 22 of the gas cylinder is closed, the solenoid valve 25 of the monitoring module is opened and the device resumes operation. The compressed air cylinder 23 can be used multiple times, reducing the number of manual maintenance and operation costs. When the compressed air is exhausted, the gas cylinder can be replaced conveniently and quickly through the maintenance window 3.

[0037] Finally, the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
