Description
The utility model relates to the pretreatment unit of being washed the gas analysis instrument that device, condenser, drying chamber, throttling valve, filter paper form by sampling probe, liquid.
The QGS-08 infrared analyzer pretreatment unit that Beijing Analytical Instrument Factory produces comprises that sampling probe, the liquid of series connection are washed device, condenser, drying chamber, throttling valve, filter paper successively, sampling probe is with steam tracing by stopple coupon, stopple coupon periphery on sampling flange, the sampling flange and forms, this sampling probe can not guarantee the temperature of sample gas, easily make sample gas in stopple coupon, separate out crystallization, thereby cause sampling line to stop up.The sample tracheae that liquid is washed device has three branch roads, and first branch road connects U-tube manometer, the stabilivolt in second branch road is provided in a side of between jar and the outer jar, jar interior draft tube in the 3rd branch road is provided in a side of.The degree of depth that stabilivolt inserts in the washing lotion is darker than draft tube, and the stabilivolt bottom is mutually concordant with the discharging tube bottom, and interior tank top is provided with the outlet of sample gas, and the outer jar that this liquid is washed device seals.When analytic system pressure increases, sample gas is still discharged from draft tube in a large number, the sample gas of walking from stabilivolt seldom, the sample gas that comes out by stabilivolt enter the lotion pipeline drag-out wash device just still less, the pressure of this all gas outlet just increases along with the increase of system pressure, and stabilivolt does not play pressure stabilization function.Again because outer jar is sealed, the gas of being discharged by stabilivolt concentrates at outer tank top and air pressure is constantly risen, for reaching pressure equilibrium, and outer jar liquid level is descended, in jar liquid level rise, cause the sample gas carrying liquid or washing lotion is pressed onto the outlet of sample gas and can't supplies gas, though again through measures such as a series of condensation, dryings, part moisture is taken in the analysis meter, cause damage.
The pretreatment unit of the gas analysis instrument that the purpose of this utility model is exactly a kind of difficult obstruction of design, voltage regulation result is good.
The utility model comprises that successively sampling probe, the liquid of series connection washes device, condenser, exsiccator, throttling valve, filter paper, the closed circuit of measurement and control that this condenser comprises semiconductor condensation piece, lean against condenser pipe on the semiconductor condensation piece, form with semiconductor condensation piece; Drying chamber comprises that sample gas outlet is established on tank body, tank body top, the import of sample gas is established in the tank body bottom, it is characterized in that sampling probe comprises that the outlet of be fixedly connected on sampling flange, the sampling flange stopple coupon and steam tracing, steam tracing inserts in the import of stopple coupon; Liquid wash device comprise be provided with in the middle of outer jar, outer jar interior jar, outer jar top be provided with leakage fluid dram, outer jar bottom be provided with survey under the liquid level mouthful, outside jar and space one side of interior jar be provided with draft tube, opposite side be provided be connected to feed tube on T shape stabilivolt, the interior tank deck and escape pipe, T shape stabilivolt top one end communicate with escape pipe, the other end be survey mouth on the liquid level, below the bottom insertion liquid level.Enter the draft tube that liquid is washed device after the temperature and humidity of sample gas and steam raising sample gas, gas in interior jar with the washing lotion counter current contacting, remove harmful gas and impurity, sample gas after the purification, arrive condenser through escape pipe, make sample air cooling but and make the most of moisture in the sample gas be condensed into water, condensate water is in time discharged from the condenser pipe bottom, in drying chamber, further remove small amount of moisture through condensed sample gas, arrive the required flow of analysis meter through throttle valve control, by arriving analysis meter behind the filter paper elimination trace impurity.The utility model directly mixes with steam owing to sample gas, sample gas temperature and humidity improves fast and even, make sample gas avoid separating out crystallization, assurance stopple coupon and liquid are washed the draft tube of device and can not stopped up, the steam that is added is washed to cool off in the device at liquid and is become water, and the sample gas water cut after the purification can satisfy requirement of the present utility model.When analyzed system pressure raises, interior jar upper space and escape pipe, stabilivolt internal pressure also raise, and when it was increased to setting, a part of sample gas was discharged to the washing lotion from stabilivolt, after the washing lotion washing, enter atmosphere, be limited in the setting thereby use atmospheric pressure.The size of setting is inserted the degree of depth decision of washing lotion by stabilivolt.
So the utlity model has be difficult for to stop up, voltage regulation result is good, Failure analysis instrument not, the advantage that life cycle is long can be widely used in carrying out the pre-service aspect before the gas analysis that contains hazardous substance.
