Below in conjunction with accompanying drawing 1, further specify the know-why and the operational process of intrinsically safe type sample gas processing system of the present invention: selecting the correct position of process pipe is sampling spot, technology stop valve one end of removable sampling probe 1 directly is welded on the process pipe, the probe stopple coupon inserts 5～20 centimetres in pipeline, and sampling is just representative like this.The analyzed sample gas of technological process enters stopple coupon from sample gas sample tap, if when stopple coupon inlet crystallization or pollution occur obstruction dangerous is arranged, can be under the sampling condition and isolating seal state of higher temperature and pressure, pull down the extraction stopple coupon and safeguard cleaning, under the isolating seal state, go in the insertion process pipeline again then.The technology stop valve of sampling probe 1 plays the isolating seal effect, and reduction valve 3 decompression is regulated pressure to the 0.12MPa, also can close and cut off sample gas.Sample gas with sample gas transfer tube 2 from on-site transfer to analyzing the cabinet 22, its distance should≤15 meters, for making it condensation blocking pipeline do not take place, be with steam tracing device 4 tracing thermal-insulatings about 120 ℃.Equipment or parts keep in repair if desired in the analysis cabinet 22, and the manual ball valve of available water cooling de-watering device 6 front ends cuts off sample gas, and tensimeter shows that sample gas enters the pressure when analyzing cabinet 22.Sample gas is after the pre-cooled pipe 5 pre-cooled reduction temperature of sample gas, send into water cooling de-watering apparatus 6, the pre-cooled pipe 5 of sample gas is exposed pads tubular constructions, because of the temperature difference plays cooling effect greatly, water cooling de-watering apparatus 6 has made up hydrocooler and two functions of components of moisture trap, complexity, cooling structure are efficiently arranged, chilled water enters from following side entrance, discharge from last side outlet, efficient cooling sample gas, its depoint depression is extremely near room temperature, and therefrom isolated condensed fluid and pollutant are arranged to condensate discharge collector 20 by automatic blowdown valve 7.Sample gas enters self-cleaning style air filter 8, have the high strength of nano-meter characteristic, the polymerization filtration membrane of low vapour lock, the dust-filtering precision is brought up to 0.05um 99%, and stop 99.9% various liquid mists to pass through, thereby play high efficiency synthetic filter effect, make sample gas more approach the high-quality of " dustless "; The by-pass of this filtrator 8 also have from purge, self-cleaning non-maintaining function, also can online in case of necessity replacing filtering membrane; Drop that by-pass is taken away and pollutant are arranged to condensate discharge collector 20 by automatic blowdown valve 7; The flow of by-pass is 3～5 times of sample airshed, is regulated by bypass flow meter 15 to show bypass flow, and the effect of accelerating the sample gas processing system reaction velocity is arranged.Need to use standard substance gas cylinder at zero point 16 and terminal point gas cylinder 17 to carry out periodic calibration at gas analyzer 11 to ensure necessary accuracy in detection, switching gas circuit when five-way transfer valve 9 is used for calibration gas analyser 11.Infiltration style air dry device 10 will use the clean source of the gas of dry pressurized air as dry sample gas, drying tube is hydrophilic sulfate material, be easy to absorb hydrone and make it pass tube wall and enter tubular shell, and the clean band of gas that is entered tubular shell walks to become wet purified gas, be that moisture all is evaporated in the purified gas, freely discharge from moisture escape hole 21, the gas molecule of other composition then can not pass through dry tube wall, and sample gas dew point further is reduced to below-6 ℃.The sample gas of this moment has been more to approach high-quality as the standard gas of " dustless ", " anhydrous ", regulate, show suitable sample airshed through sample airshed meter 14, flow to online gas analyzer 11 and carry out safety, continuous, stable, reliable, high-precision test analysis.If sample atmospheric pressure＜0.01MPa needs to adopt pneumatic sampling pump 12 negative pressure suction sample gas.Pneumatic sampling pump 12 can only place after the gas analyzer 11; Pneumatic sampling pump 12 is to make driving force with the pressurized air of certain pressure and flow, and the pressurized air that pneumatic sampling pump 12 and infiltration style air dry device 10 use is all used pressure maintaining valve 19 decompressions and shown pressure, regulates with compressed air require meter 18 to show flow; After sample gas that pneumatic sampling pump 12 is discharged and pressurized air and by-pass compile, discharge with secured fashion from the safety dumping cover 13 of being with spark arrester.Condensate discharge collector 20 compiles after condensed fluid, pollutant and the chilled water, and also the mode with safety is discharged into suitable place, to prevent the pollution of the environment.
Above-mentioned whole sample gas disposal parts are all without 220V AC AC power, thereby are safe, can reduce explosion-proof input greatly.
Above the present invention is described in detail, has used specific case herein principle of the present invention and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present invention and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, all have flexible change part in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
