Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, SO in a kind of heat-engine plant desulfurized tower exiting flue gas2Concentration sampling analysis device, including the powder being sequentially connected with
Dirt defecator 1, SO2Adsorbent equipment 2, gas flowmeter 4 and air pump 5, described dust filtering device 1 is electrostatic precipitation
Device, utilizes high voltage electric field to make flue gas ionize, and dust in air-flow is charged to be separated with air-flow under electric field action, to sampling gas
Body carries out preliminary purification, reduces dust to SO2The impact that concentration measures.As in figure 2 it is shown, described SO2Adsorbent equipment 2 wraps
Include housing 21, described housing 21 can arrange radiating fin, increase area of dissipation, the gas sampled of high temperature is lowered the temperature,
Multiple adsorbent block 22 it is sequentially provided with, it is possible to form level, make the SO in gas sampled in described housing 212Adsorb more thorough
The end.Described adsorbent block 22 is provided with some first through holes, arranges the first through hole, by increasing capacitance it is possible to increase the adsorption plane of adsorbent block 22
Long-pending, improve adsorbent block 22 further to SO2Adsorption effect.Described first through hole is inclined hole, the inclination of described first through hole
Direction is contrary on adjacent two adsorbent blocks 22, and the first through hole is set to the inclined hole on inclination adjacent two adsorbent blocks 22
Incline direction is contrary, it is possible to slow down the flow velocity of gas sampled, makes gas sampled at SO2Abundant and adsorbent block in adsorbent equipment 2
22 contacts.Described SO2The arrival end of adsorbent equipment 2 is provided with gas diverter 23, it is possible to entering SO2Adsorbent equipment 2
Gas sampled be diffused shunting, make gas sampled scatter, it is to avoid a point of blow-through adsorbent block 22, increase adsorbent
The burden of block 22.Described gas diverter 23 is a conical piece, and described conical piece is provided with and some is parallel to high line
Second through hole, can be tentatively to entering SO through the second through hole2The gas sampled of adsorbent equipment 2 is slowed down.Described second leads to
Hole is arranged ringwise.Described second through hole is gradually tilted to the summit of cone to outer shroud by ring.Make the second through hole towards all
Point to summit, contribute to the circulation of gas.The bus of described circular cone is the concave arc internally caved in, housing 21 be provided with
