For this reason, the utility model adopts following technical scheme:
A kind of continuous analytical sampling pretreatment unit of hyperchannel being applicable to dirt and wet gas, comprise dirt and wet gas outlet conduit, some dilution tunnels are provided with in described dirt and wet gas outlet conduit, described dilution tunnel is connected with hay tank by by-pass valve control, the exit of described hay tank is provided with dust-removal cloth-bag, the outlet of described hay tank is connected with sample gas conveying arm, described sample gas conveying arm is connected with aspiration pump, the end of described sample gas conveying arm is connected with sample gas delivery main respectively, described sample gas delivery main is connected with buffer tank in turn, accurate filter and suspended body flowmeter, the end of described sample gas delivery main connects gas analyzer.
Further, described sample gas conveying arm position between hay tank and aspiration pump is connected with anti-blowpipe, described anti-blowpipe is connected with blowback operation valve.
Further, the drainage face, end of described dilution tunnel is in 45 ° of grooves.
Further, described dilution tunnel is inserted into dirt and wet gas outlet conduit internal diameter 1/3 place perpendicular to dirt and wet gas outlet conduit.
Further, described dust-removal cloth-bag is glass fibre dust-removal cloth-bag.
The beneficial effects of the utility model are:
1, any gas circuit parallel running or the single channel method of operation can be selected voluntarily to carry out gas sample, can when gas analyzer not interruption of work, manual fixed point, timing cleaning be any road dilution tunnel or replacing dust-removal cloth-bag wherein, achieves the object of dynamic on-line continuous sampling;
2, due to 45 ° of bevel design in drainage face, dilution tunnel end, representative for dirt and wet gas outlet conduit central point sample gas can take out by dilution tunnel, can avoid gas laminar flow and vortes interference again;
What 3, adopt easily maintenance adds glass fibre cloth bag dedusting method straight through filter tank, various dust in sample gas are realized at dust-removal cloth-bag place efficiently " physical separation ", overcomes traditional major defect that the existence of rigid surface pore type filtrator easily blocks, the life-span is short;
4, the utility model structure is simple, use is changed conveniently, filtration cleaning efficiency is high, maintenance is little; Can realize gas circuit switch before bleed in advance, alternately on-line period and timing nitrogen blowback and a lot of dust glass fibre cloth bag deashing automatically.
