[0002] When the boiler flue gas is discharged through the chimney pipe, real-time component detection is generally required to ensure that the flue gas components are not discharged exceeding the standard. At present, the flue gas is generally sampled from the chimney through a flue gas sampling probe. After obvious soot particles are filtered by a ceramic filter tube, it is then transported to the monitoring cabinet through a pipeline for real-time component analysis. However, in the pre-treatment process of the flue gas at the outlet of some boilers, there are relatively more water vapor and residual tar. In order to avoid the condensation of water vapor and the adhesion of tar during transportation, a heat tracing pipeline is generally used. However, after the sampled flue gas is transported into the component analyzer in the monitoring cabinet, since the water vapor and tar are not treated, and continuously introduced into the flue gas component analyzer, there will be phenomena of water vapor condensation and tar retention, which will have an adverse impact on the flue gas component analyzer. In addition, the flue gas transported through the heat tracing pipeline still has relatively more heat, and directly and continuously introduced into the monitoring cabinet, it is easy to cause the problem of high heat load of the electronic components in the monitoring cabinet.

The exhaust pipe 12 penetrates through the monitoring cabinet 1 to the outside. Start the air-cooled refrigeration unit 4,The output end of the air-cooled refrigeration unit 4 continuously conveys cold air into the air-cooled box 5. The condensate pipe 6 is rapidly cooled by the cold air. The water vapor in the flue gas in the condensate pipe 6 will be rapidly cooled and condensed into liquid water droplets, and the remaining tar will be mixed in the water droplets. The liquid water droplets mixed with tar will accumulate in the filter box 9, thereby greatly reducing the content of water vapor and tar in the flue gas finally introduced into the flue gas analyzer, and effectively reducing the adverse effects of water vapor and tar on the flue gas analyzer. Connection ports are respectively arranged on the side surface of the filter box 9 corresponding to the conduit one 8 and the conduit two 10. Hoop fasteners are sleeved between the conduit one 8 and the conduit two 10 and the connection ports. Connection ports are respectively arranged on the side surface of the filter box 9 corresponding to the conduit one 8 and the conduit two 10. Hoop fasteners are sleeved between the conduit one 8 and the conduit two 10 and the connection ports, which facilitates the quick disassembly of the connection between the filter box 9, the conduit one 8 and the conduit two 10, and facilitates the removal, maintenance and replacement of the filter box 9. The connection ports of the filter box 9 are all opened on the upper side of the side surface. The height of the connection ports affects the collection capacity of the filter box 9. The connection ports of the filter box 9 are all opened on the upper side of the side surface.

[0037] During use, the flue gas sampling device is connected to the heat tracing pipeline, and the heat tracing pipeline is connected to the input end of the condenser 6. The sampled flue gas is transported through the condenser 6. The air-cooled refrigeration unit 4 is started, and the output end of the air-cooled refrigeration unit 4 continuously transports cold air into the air-cooled box 5. The condenser 6 is quickly cooled by the cold air, and the water vapor in the flue gas in the condenser 6 will quickly cool and condense into liquid water droplets. The remaining tar will be mixed in the water droplets, and then it will be sent into the filtration box 9 through the control valve 1 7 and the conduit 1 8. The liquid water droplets mixed with tar will accumulate in the filtration box 9. After that, the remaining flue gas will enter the flue gas composition analyzer 3 through the conduit 2 10 and the control valve 2 11 for composition analysis. The analyzed flue gas will finally be discharged from the exhaust pipe 12. Thus, before the flue gas enters the flue gas composition analyzer, the water vapor and remaining tar in the flue gas can be condensed and liquefied and collected, thereby greatly reducing the content of water vapor and tar finally introduced into the flue gas composition analyzer, and effectively reducing the adverse effects of water vapor and tar on the flue gas composition analyzer. In addition, during use, connection ports are respectively provided on the side surface of the filtration box 9 corresponding to the conduit 1 8 and the conduit 2 10. Hoop joints are sleeved between the conduit 1 8 and the conduit 2 10 and the connection ports, which facilitates the quick disassembly of the connection between the filtration box 9, the conduit 1 8 and the conduit 2 10, and is convenient for removing the filtration box 9 for maintenance and replacement. In addition, the height of the connection port affects the collection capacity of the filtration box 9. The connection ports of the filtration box 9 are all opened on the upper side of the side surface. In order to increase the effective capacity of the filtration box 9, in addition, porous ceramic filter balls 91 are filled in the filtration box 9. The contact surface of the porous ceramic filter balls 91 can greatly increase the adsorption effect on the liquefied water droplets and tar, thereby increasing the collection effect on the liquefied water droplets and tar. In addition, a partition 92 is provided in the middle of the inner side of the filtration box 9. Fine holes are opened on the side surface of the partition 92. The connection ports are respectively arranged on both sides of the partition 92. After the flue gas enters the filtration box 9, the fine holes of the partition 92 have a slower passing speed for the flue gas, thereby increasing the contact time between the flue gas and the porous ceramic filter balls 91, and further increasing the collection effect on the liquefied water droplets and tar. In addition, a cleaning port is opened on the lower side of the side surface of the filtration box 9. The diameter of the cleaning port is larger than the diameter of the porous ceramic filter balls 91. There is a gap between the bottom of the partition 92 and the filtration box 9, and the gap is larger than the diameter of the porous ceramic filter balls 91. A sealing plug 93 is hermetically inserted at the cleaning port for discharging the water mixture collected in the filtration box 9, and is convenient for pouring out the porous ceramic filter balls 91 for cleaning and replacement. A transparent glass window is opened on the side surface of the filtration box 9 for observing the collection situation of the water mixture in the filtration box 9. In addition, the air-cooled box 5 is arranged between the inner side walls of the flue gas composition analyzer 3 and the monitoring cabinet 1. An air outlet is opened on the upper side of the air-cooled box 5. Cold air passes through the air-cooled box 5, and finally the continuous cold air is directly blown into the monitoring cabinet 1, which can increase the heat dissipation effect on the monitoring cabinet 1. Heat dissipation plates 51 are evenly arranged on the inner side of the air-cooled box 5, which can increase the heat contact area, thereby increasing the heat exchange effect.
