DETAILED DESCRIPTION

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] like Figure 1 As shown, a flue gas emission monitoring and display device for a gas-fired steam combined cycle unit includes a flue gas monitoring platform 1. The upper part of the flue gas monitoring platform 1 has an opening, and a display 2 is installed at the opening. A U-shaped housing 3 is installed below the display 2. Fixing ears 4 are fixedly installed at both ends of the housing 3. The fixing ears 4 are fixedly connected to the inside of the flue gas monitoring platform 1 via screws 5. A control panel 6 is installed below the display 2 of the flue gas monitoring platform 1. A processor 7 is installed inside the flue gas monitoring platform 1. The processor 7 can be electrically connected to the display 2 and the control panel 6 for data signal transmission. The processor 7 can also be electrically connected to a socket 8 built into the flue gas monitoring platform 1. The lower part of the flue gas monitoring platform 1 is connected to a cooling gas inlet pipe 9, and the upper part of the flue gas monitoring platform 1 is connected to a cooling gas outlet pipe 10. An outlet pump 11 is installed on the cooling gas outlet pipe 10. In use, this utility model introduces low-temperature gas into the flue gas monitoring station 1 through the cooling gas inlet pipe 9 to exchange heat with the flue gas monitoring station 1. Under the action of the outlet pump 11, the gas is discharged through the cooling gas outlet pipe 10, thus conveniently completing the heat exchange operation in the flue gas monitoring station 1.

[0017] Specifically, the housing 3 described in this embodiment is made of a material with high thermal conductivity, and several heat dissipation fins 12 are provided on the bottom of the housing 3. In this invention, the heat dissipation fins 12 can quickly dissipate heat from the display 2, making it convenient to use.

[0018] Specifically, in this embodiment, a ramp 13 is provided at the lower part of the cooling gas outlet pipe 10, and the highest point of the ramp 13 is higher than the highest point of the display 2. In this utility model, the ramp 13 can guide the low-temperature gas introduced into the flue gas monitoring station 1 from the cooling gas inlet pipe 9 towards the display 2 as the gas outlet pump 11 moves it upward, thereby improving the heat exchange efficiency.

[0019] Further, the bottom of the display 2, the bottom of the control panel 6 and the side of the processor 7 are respectively provided with a temperature sensor 14. The temperature sensor 14 can monitor the temperature of the display 2, the control panel 6 and the processor 7 in real time, so that the cooling operation is performed in time when the temperature exceeds the specified range, and use is facilitated.

[0020] Further, the cooling gas inlet pipe 9 is provided with a one-way valve 15. The one-way valve 15 can prevent the gas in the smoke monitoring console 1 from flowing out through the cooling gas inlet pipe 9, and ensure the normal use of the cooling operation.

[0021] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the utility model, and not to limit them; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
