Embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
As shown in Figs. 1-3, a kind of anti-interference sampling apparatus of boiler back end ductwork gas, including upper cover, by outer barrel, inner cylinder structure
Into cylinder, the inner cylinder is arranged in outer barrel, and inner cylinder upper and lower side is not closed, and upper cover is arranged on inner cylinder upper end, the outer barrel
Lower part is provided with connector, at connector releasable connection have collecting vessel, metal filtering core is provided with inner cylinder, metal filtering core is arranged on
Upper cover downside, inner cylinder top are provided with fairlead, and fairlead input terminal is connected with metal filtering core, and fairlead output terminal is used for
Connection smoke filter or preprocessor, outer barrel top side have been horizontally disposed with a sample probe.
In the present embodiment, the upper cover is threadedly coupled with inner cylinder, and collecting vessel is threadedly coupled with outer barrel.
In the present embodiment, it is provided with rubber seal between the upper cover and cylinder.
In the present embodiment, the outer barrel, inner cylinder lower part are in up big and down small frustum.
In the present embodiment, sample probe be stainless steel tube, fairlead be copper pipe, filtration liner is externally provided with strainer, filtering
Pad as cotton pad or gauze liner.
In the present embodiment, the sample probe, fairlead are metal tube, and ground connection is provided with sample probe, fairlead
Line.
In the present embodiment, ground wire and sample probe, fairlead soldering, sample probe is stainless steel tube, fairlead is
Copper pipe.
In the present embodiment, the metal filtering core is brass filter core or stainless steel filter core.
In the present embodiment, when measuring SO2 when gas, it is necessary to allow tested gas to maintain certain temperature, to prevent water
Steam condenses, and at this moment needs to use the connecting tube with heating, it is worth mentioning at this point that in this case, the outer drum outer wall should also be set
Heating unit, the heating unit are 24V silica gel heat tapes, and silica gel heat tape electrically connects with temperature controller, transformer
Connect, silica gel heat tape can look for manufacturing firm to customize, and shape should be able to be close on outer barrel, it is preferred to use 24V（Alternating current-direct current
