Description
Technical field
The present invention relates to gas detection technical field of tools, more particularly, to a kind of chimney tail gas sampling pipe and its make
Use method.
Background technique
The chimney sampling apparatus being commercialized on the market can only all operate on the chimney for have thieff hatch, due to ship chimney
Structure is special, and the exhaust gas concentration of discharge is high, temperature is high, opens thieff hatch and may cause toxic gas and leaks into cabin, jeopardizes the person
Safety, therefore ship chimney is without thieff hatch.It is directly protruded into from ship chimney exhaust outlet currently, some monitorings mainly pass through
The mode of sampling pipe is monitored sampling.But sampling pipe is directly put in into chimney exhaust outlet and is acquired, due to rushing for air-flow
It hits, sampling pipe itself is easy to cause constantly to rock, even result in sampling pipe and chimney occurs to hit and suck the product on chimney wall
Dirt or blocking sampling pipe, seriously affect sampling quality and sampling efficiency.In addition, flue gas is on stack cross section and non-uniform Distribution,
Stack cross section different location must accurately be sampled, can just obtain representative monitoring result.Moreover, many chimneys
Height and position is different, bore position is different, there is high requirement to the controllability of sampling pipe.Therefore, a kind of satisfaction is designed
The sampling pipe of application has great importance.
