Preferably, the flange cylinder is made of partition board two parts of direct tube section and bottom.
The technical characteristics of the utility model also resides in：Described device further includes the connection that can be slided along flange cylinder inner wall
Inner cylinder；The front end for connecting inner cylinder is equipped with connecting plate, which is threadedly coupled by screw rod and flange cylinder front end face, and even
It connects and spring is set between inner cylinder and partition board.
Preferably, thermal insulation layer is set on the medial surface of the connecting plate.
The utility model compared with prior art, has the following advantages and advantageous effect：1. the utility model is in flue
Flange cylinder is set, and flue gas transfers heat to purging air pipe by flange cylinder, makes the gas temperature in purging air pipe
Always with the temperature close of flue gas, not only without electrical heating waste of energy, but also the temperature of purge gas need not be carried out constantly
Monitoring.Flange cylinder also is able to the pernicious gas in flue gas being isolated simultaneously, and flue gas is avoided to cause to corrode to purging air pipe, from
And increase the service life of purging air pipe, without often being safeguarded to purging air pipe；2. the company of setting in flange cylinder
Inner cylinder and spring are connect, such structure is adjusted when gap on the one hand can be generated between flange cylinder and flue, simultaneously also
Preferably purging air pipe can be fixed in flange cylinder.3. the device have it is simple in structure, convenient for safeguard and energy-saving ring
The advantages that guarantor.

Specific embodiment
The concrete structure of the utility model, principle and the course of work are described further below in conjunction with the accompanying drawings.
Principle schematic diagrams of the Fig. 1 for the first embodiment of the utility model, smoke sampling probe hot blow sweeping device
Including air source 1, sampling probe 2, purging air pipe 3 and flange cylinder 8；The flange cylinder 8 is arranged in flue 15, flange circle
The front end face of cylinder is tightly connected with flue wall surface；One end of purging air pipe is connect with air source 1, the other end by flange cylinder and
Sampling probe 2 is connected, and one section of pipeline of purging air pipe 3 is located in flange cylinder 8.It is also equipped on purging air pipe 3
Solenoid valve 4.This structure can heat flange cylinder 8 using flue gas, and flange cylinder 8 transfers heat to purge gass again
Pipeline 3, make gas temperature in purging air pipe 3 always with the temperature close of flue gas, both without electrical heating waste of energy,
The temperature of purge gas need not be monitored constantly again.For the ease of installing and safeguarding, flange cylinder can also make split
