[0016] As shown in Figure 1 the utility model discloses a flue gas sampling probe heat conducting device, it includes sleeve 100 and heat conducting cylinder 200, sleeve 100 is used to suit heat conducting cylinder 200, so that the inner diameter of sleeve 100 is greater than the outer diameter of heat conducting cylinder 200, so that heat conducting cylinder 200 is installed in the cylinder of sleeve 100, when installing heat conducting cylinder 200, need to ensure that heat conducting cylinder 200 and sleeve 100 are coaxially installed. The outer wall of heat conducting cylinder 200 is provided with a plurality of heating pipes 210 distributed along the axial direction, the heating pipe 210 is used to transmit the heat collected to heat conducting cylinder 200, and heat conducting cylinder 200 transmits the heat to sampling probe 300.
[0017] In the utility model, connecting seat 110 is arranged at one end of sleeve 100, so that the end of sleeve 100 is connected with sampling probe 300 through connecting seat 110, and a sealing ring is arranged between sleeve 100 and connecting seat 110. The other end of sleeve 100 is connected with sampler 400 through flange 120, and heating pipe 210 needs to be in conduction with heating system 410 of sampler 400, so that the heat of heating system 410 is transmitted to the heating pipe.
[0018] In the utility model, in order to facilitate the installation of heat conducting cylinder 200, mounting surface 130 for abutting heat conducting cylinder 200 is arranged at the end of sleeve 100, when installing heat conducting cylinder 200, heat conducting cylinder 200 is abutted against mounting surface 130.

[0019] In this utility model, a heat insulation cotton 140 is also provided inside the sleeve 100. The heat insulation cotton 140 covers the outside of the heating tube 210 to prevent heat loss and at the same time prevent the heating tube 210 from transferring heat to the sleeve 100, thereby preventing burns to the operator and ensuring the safety of the operator.
[0020] In this utility model, in order to increase the contact area between the heating tube 210 and the heat-conducting cylinder 200, a number of grooves 220 distributed along the axial direction are provided on the outer wall of the heat-conducting cylinder 200.

Then, the connecting seat 110 is installed at the front of the sleeve 100, and the entire heat-conducting device is assembled. After the heat conduction device is assembled, it is directly fitted onto the sampling probe 300 of the existing sampler 400. The sleeve 100 is connected and fixed to the sampler 400 through the flange 120. In this way, the heating tube 210 is connected to the internal heating system 410 of the sampler 400 through the flange 120. The sampler 400 automatically adjusts the heating temperature to the set value through its own temperature control system. Heat is introduced into the sampling probe 300 through the heating tube 210 and the heat conduction cylinder 200 to ensure that the outer surface temperature of the sampling probe 300 is higher than the flue gas dew point temperature, thereby preventing flue gas condensation.
