Further, described ash releasing tube and described exit flue tilt to install, and are less than 90 degree with the angle of described exit flue.
Further, described sampling line is provided with blower fan flue gas being delivered to the exhaust end of described sampling line by the inlet end suction of described sampling line.
Further, the inlet end of described stock layout pipeline is positioned at the upstream of the flue gas flow direction of described exit flue, and exhaust end is positioned at the downstream of the flue gas flow direction of described exhaust uptake.
Further, described analyser is arranged on the sampling line between described dust arrester and described blower fan.
The utility model obtains the flue gas in exit flue by sampling line, exhaust gas volumn during measurement can be reduced, reduce the flue gas flow rate entered in sampling line simultaneously, and then make the dust in flue gas obtain sedimentation, the dust content entered in analyser is reduced, decrease the probability that analyser is blocked, and then extend the serviceable life of analyser.
The present embodiment can reduce the maintenance work of analyser, conveniently extracts flue gas, and can obtain accurate analysis result, and extends the serviceable life of analyser.
Accompanying drawing explanation
Fig. 1 is the purification plant structural representation according to the utility model embodiment;
In figure: 10-exit flue, 20-sampling line, 21-inlet end, 22-exhaust end, 30-analyser, 40-dust arrester, 41-funnel, 42-ash releasing tube, 50-blower fan.
Embodiment
As shown in Figure 1, the extraction-type flue gas analysis instrument purification plant of the utility model embodiment comprises in general manner, for the flue gas of boiler being delivered to the exit flue 10 sent again after flue gas processing device processes, with the sampling line 20 that the opening by two ends is communicated with exit flue 10 respectively, and be arranged on sampling line 20 for the analyser 30 of analysis stream through the flue gas of sampling line 20.
The flue gas processing device of the present embodiment refers to the cleaning system of flue gas being carried out to desulphurization denitration process, the flue gas in exit flue 10 is obtained by sampling line 20, exhaust gas volumn during measurement can be reduced, reduce the flue gas flow rate entered in sampling line 20 simultaneously, and then make the dust in flue gas obtain sedimentation, the dust content entered in analyser 30 is reduced, decreases the probability that analyser 30 is blocked, and then extend the serviceable life of analyser 30.At the both ends open place of sampling line 20, can switch valve being set, with when not sampling, closing sampling line 20.
The present embodiment can reduce the maintenance work of analyser 30, conveniently extracts flue gas, and can obtain accurate analysis result, and extends the serviceable life of analyser 30.The scheme of the present embodiment is not only applicable to power industry, needs to analyze flue gas equally, as the industry such as chemical industry, metal smelt is applicable equally at some other.
Further, in an embodiment of the present utility model, for reducing the dust content in flue gas, at the inlet end 21 of sampling line 20, the dust arrester 40 filtering dust in flue gas can be set.The dust-filtering flowed through in the flue gas of sampling line 20 can be fallen by dust arrester 40, reduce dust further to the impact of analyser 30.
In the present embodiment, this dust arrester 40 can adopt electrostatic precipitation mode, also can adopt the filtration of filter screen one class.
For avoiding dust arrester 40 place to accumulate dust, this dust arrester 40 place can arrange the dust exhaust that the dust after by filtration drains back to exit flue 10.Directly the dust after filtration can be discharged by dust exhaust, avoid the analytical effect piling up rear impact analysis instrument 30.
Concrete dust exhaust can comprise the funnel 41 accepted and filter rear dust, and by the direct dispatch of dust in funnel 41 to the ash releasing tube 42 of exit flue 10.In the exit of ash releasing tube 42, can one-way cock be set, pours in down a chimney to avoid the flue gas in exit flue 10.In other embodiments, also can be directly connected with exit flue 10 by funnel 41.Directly dust arrester 40 can also be arranged on the opening part of the inlet end 21 of sampling line 20, the dust after filtration is directly dropped in exit flue 10.
