Embodiment
See also Fig. 1 and Fig. 2, integrated sampling of the utility model and pretreatment unit, this device 1 are mainly formed by extracting probe 11, the pneumatic sampling ball valve 12 of stainless steel, moisture trap 13, peristaltic pump 14 and stainless steel blowback solenoid valve 15 fully; Wherein:
Moisture trap 13 mainly is made up of main body 134, upper press cover 135 and lower cover 136, these upper and lower two glands 135,136 from two side pressures and are positioned at middle main body 134, on this upper press cover 135, be furnished with the input port 131 and the delivery outlet 133 that connect with this moisture trap 13, on this lower cover 136, be furnished with the delivery outlet 132 that connects with this moisture trap 13; The material selection boric acid silica glass tube of this main body 134, the material selection teflon of these two glands 135,136.
The thief hatch A that extracts probe 11 fully is communicated to an end of the pneumatic sampling ball valve 12 of stainless steel through the stainless-steel tube of one section preset length, the other end of the pneumatic sampling ball valve 12 of this stainless steel is communicated to the input port 131 of moisture trap 13 through the stainless-steel tube of one section preset length, the delivery outlet 132 of this moisture trap 13 is communicated to peristaltic pump 14 through the stainless-steel tube of one section preset length, another delivery outlet 133 of this moisture trap 13 is communicated to high temperature sampling pipeline (not shown), and this peristaltic pump 14 also is communicated in a drainpipe (not shown).
In addition, stainless steel blowback solenoid valve 15 stainless-steel tubes through one section preset length are communicated in this back blow port B that extracts probe 11 fully, the material selection stainless steel 316L of this stainless steel blowback solenoid valve 15.
The pneumatic sampling ball valve 12 of described stainless steel, moisture trap 13, peristaltic pump 14 and stainless steel blowback solenoid valve 15 all are fixed on the support 16, this support 16 is fixed on this first fixed frame 171, thus, Jin Cou arrangement has been saved the space widely; And as shown in Figure 2, be distributed with the hollow-out parts 161 of a plurality of strips on the side of this support 16, make under the prerequisite of the intensity that does not influence this support 16, alleviated the weight of this device 1 significantly, and reduced cost.
In implementation process, flue gas enters heating region 1131 through the stopple coupon 112 that extracts probe 11 fully, adding thermal control units 113 makes the temperature of heating region 1131 about 350 ℃, because extract the material selection stainless steel 316L of probe 11 fully, seal 115 has been selected high pressure XB450 it-plate for use, but 450 ℃ of heatproofs, so can satisfy the work requirements that this extracts probe 11 fully.Flue gas filters by ceramic element 114, elimination the particle of diameter greater than 1 μ, input port 131 by stainless-steel tube, the pneumatic sampling ball valve 12 of stainless steel, moisture trap 13 enters into moisture trap 13 again, because moisture trap 13 is under the normal temperature, water in the flue gas and crystal can condense rapidly, but simultaneously because crystal is very easily water-soluble, so the crystallization meeting is along with condensate water is drained by peristaltic pump 14 by delivery outlet 132, peristaltic pump 14 twenty four hours continuous workings can guarantee that the water in the moisture trap 13 can spill-over.Flue gas is handled the back through moisture trap 13 directly can enter high temperature sampling pipeline by delivery outlet 133; such flue gas has been removed most particles, water, saline crystallization; play pretreated effect, protected the serviceable life and the measuring accuracy of the pipeline and the analyser (not shown) in downstream biglyyer.
Stainless steel blowback solenoid valve 15 in the device 1 is controlled by external signal; the time opening blowback; the pneumatic sampling ball valve 12 of stainless steel was closed when stainless steel blowback solenoid valve 15 was opened; do not damaged with protection moisture trap 13 by the pressurized air that blowback solenoid valve 15 is produced; pressurized air enters in the ceramic element 114 that extracts probe 11 fully by blowback solenoid valve 15 and back blow port B successively, and the particle in the ceramic element 114 is blown in the air-returen flue again.Just can guarantee that so also the ceramic element 114 that extracts probe 11 fully can not stop up because of working long hours, the continuous operation that whole device also can the longer time guarantees the online rate of whole flue gas discharge continuous monitoring system, improves the usability of total system.
In sum, this device adopts and extracts probe 11 fully, increases heating power, and heating-up temperature guarantees more than 350 ℃, guarantees not have saline crystallization to produce in ceramic element 114 with this.This extracts the sealing gasket of probe 11 inside fully simultaneously, and encapsulant is selected high pressure XB450 it-plate for use, but 450 ℃ of heatproofs guarantee to extract probe 11 fully when being heated to more than 350 ℃, all sealing gaskets can normally use.Moisture trap 13 mainly plays the water in the nature condensation flue gas, and the saline crystallization in the flue gas forms solid-state at normal temperatures and is dissolved in condensate water simultaneously, is drained by peristaltic pump 14 in the lump.Blowback solenoid valve 15 in the device 1, regularly open ceramic element 114 is carried out blowback, guarantee the dust containing capacity of filter core 114, just can guarantee that so also ceramic element 114 can not stop up because of working long hours, at exhanst gas outlet the pneumatic sampling ball valve 12 of stainless steel is installed simultaneously, when popping one's head in blowback, close pneumatic sampling ball valve 12, to guarantee that upstream device is not damaged, thus, whole device also can the longer time continuous operation, guarantee the online rate of whole flue gas discharge continuous monitoring system, improve the usability of total system.
More than be illustrative to description of the present utility model; and it is nonrestrictive; those skilled in the art is understood, and can carry out many modifications, variation or equivalence to it within spirit that claim limits and scope, but they will fall in the protection domain of the present utility model all.
