Detailed Description

The invention will be further elucidated with reference to the drawings and the embodiments, which are exemplary only and do not limit the scope of the invention.

As shown in fig. 1, a high-pressure gas heating device of an extraction type smoke dust monitor comprises a heat conductor 1, a heating mechanism 2 and two connectors 3; the heating mechanism 2 is arranged on the heat conductor 1; an air inlet and outlet channel 11 which extends along the peripheral edge of the heat conductor 1 and two ports of which penetrate through the outer wall surface of the heat conductor 1 is also arranged in the heat conductor 1, and two ports of the air inlet and outlet channel 11 are respectively used for air inlet and air outlet; two connectors 3 are respectively installed at two ports of the air inlet and outlet channel 11 and connected with the heat conductor 1.

Preferably, a mounting groove (not shown) is formed on a surface of the heat conductor 1; the heating mechanism 2 is embedded into the mounting groove; as a preferred mode, the mounting groove is provided in the middle of one surface of the heat conductor 1, thereby enabling the heating mechanism 2 to heat the heat conductor 1 more uniformly and more quickly. And through setting up the mounting groove then can make the staff conveniently dismouting heating mechanism 2, also can make this high-pressure gas heating device of extraction formula flue gas monitor's whole volume less.

Preferably, both ends of the gas inlet/outlet passage 11 penetrate through the wall surface of the same side wall of the heat conductor 1. Through the arrangement, the air inlet and outlet channel 11 can have a long length, so that high-pressure air can have sufficient time to be heated.

Preferably, in order to prevent the two joints 3 from leaking air, a sealing ring 4 is provided at the joint of the two joints 3 and the heat conductor 1 for sealing.
