Description
Technical field
The present invention relates to environment monitoring device technical field, more particularly to a kind of it is used to carrying out continuous sampling to flue gas adopting
Sample device.
Background technology
Stationary source smoke on-line monitoring system is divided into direct extraction, in-situ method and dilution according to sample mode difference
Extraction method.The sampling flowsheet of extraction method is, flue gas by the thief rod of insertion chimney, sampling probe filter, sample-taking tracing pipe,
Pre-process, finally enter analyzer.Thief rod is generally stainless steel tube of the diameter in 20mm or so, its function is insertion cigarette
Chimney (inside) designated position make flue gas via the thief rod mouth of pipe suck, some can add a filter screen in the mouth of pipe, to flue gas into
The preliminary filtering of row.Because thief rod directly contacts flue gas, so to its material requirements anti-corrosion.Sample pole length caliber and sampling flow velocity
It can influence the response time of systematic sampling analyzer, dilution method system especially small to sampling quantity.First have to first in thief rod
Smoke evacuator just can guarantee that new flue gas enters.And flue gas flows at chimney (road) moment, detection flue gas should be with current stream
The flue gas of sampled bar entrance is synchronous, just can guarantee that the continuity of flue gas measurement data.And common thief rod can not improve in itself
Response time, can only shorten the response time by increasing sampling quantity, can so increase the maintenance of sampling filter core, can also accelerate
The corrosion and ageing of pretreatment system.The connection mode of common sampling probe filter core is using being threadedly coupled, since flue gas is prolonged
Corrosion, can cause filter core not easy to remove.
Now common is stainless steel tube (or the pipe of other anti-corrosion materials of an insertion chimney (chimney) using thief rod
Body), it can only meet that the sampled bar of flue gas enters the needs of probe, without other functions, it is necessary to by suitably increasing sampling quantity
3-5 times of system actual demand amount (generally) improves the response time, and higher sampling quantity can shorten in smoke measurement system
The service life of all parts.
The content of the invention
The defects of the technical problem to be solved in the present invention is for the prior art, there is provided a kind of structure design is more reasonable, rings
