Description
Technical field
The utility model relates to a kind of new gas pretreating device, and particularly one is applicable to the mass spectrometric new gas pretreating device of process gas.
Background technology
In actual production environment, gaseous sample is in different temperature, air pressure, humidity, has particle, corrosivity etc., therefore actual sampling environment need be adopted to have the sampling system of height endurability, and need have suitable sample gas purification function.
Sampling system also should have multi-point sampling function, analyzes while realizing different monitoring points.Also must have hazardous gas and upgrade fast and low-residual characteristic.In addition, due to mass spectrometric response signal and sample introduction pressure exponentially relation, gas sampling pressure must be controlled to ensure stability and the repeatability of instrument.
As can be seen here, for needing through a series of pretreatment procedure before the sampling of mass spectrometer, and prior art can the complete device of the above-mentioned work of complete independently, the Functional Unit device that interim access is corresponding according to actual needs often, causes mass spectrometer pre-treatment job stability, reliability lower.
Summary of the invention
The utility model technical issues that need to address are: stability and the reliability of existing mass spectrometer pre-treatment work are lower.
The utility model takes following technical scheme:
A kind of mass spectrometer pretreating device, it is characterized in that: comprise housing, described housing is provided with injection port 1, described injection port 1 is communicated with by the entrance of sample channel with vertical strainer tube 2, the bottom of described strainer tube 2 is provided with drainage arrangement, the bottom of described housing is provided with freeing port 8, and described freeing port 8 is connected with drainage arrangement; The gas outlet on the top of strainer tube 2 is communicated with pressure maintaining valve 3 entrance, the outlet of pressure maintaining valve 3 is communicated with output filter and carries out fine filtering, be communicated with the outlet 5 on housing after fine filtering, described pressure maintaining valve 3 also has pressure relief opening, and described pressure relief opening is communicated with the exhaust vent 7 on housing; The outside of the outward extending pipeline of described outlet 5 is provided with heating arrangement 6.
The feature of the technical program is: the mass spectrometer pretreating device providing a kind of commercialization, by filtration unit, stable-pressure device, drainage arrangement, heating arrangement is organically combined in a housing, and arranged by the rationalization of pipeline, achieve and a kind ofly can realize dedusting simultaneously, dewater, the new gas pretreating device being specifically designed to process gas mass spectrometer of foam-expelling, pipeline temperature control and voltage stabilizing function.
Further, described drainage arrangement is provided with automatic drain valve 4.
Further, described housing is rectangular parallelepiped.

The beneficial effects of the utility model are:
1) simultaneously for mass spectrometer gas sampling, achieve dedusting simultaneously, dewater, foam-expelling, pipeline temperature control and voltage stabilizing function.
2) mass spectrometer employing gas pretreatment procedure rear stability, reliability improve greatly.
3) mass spectrometer adopts gas pre-treatment convenient.
4) commercialization of mass spectrometer pre-treatment work is achieved.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model mass spectrometer pretreating device.
In figure, 1. injection port, 2. strainer tube, 3. pressure maintaining valve, 4. drainage arrangement, 5. outlet, 6. heating arrangement, 7. exhausr port, 8. freeing port.
Embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.
Goal of the invention of the present utility model is: provide a kind of and have dedusting, dewater, the new gas pretreating device being specifically designed to process gas mass spectrometer of foam-expelling, pipeline temperature control and voltage stabilizing function.Embodiment is as follows:
See Fig. 1, a kind of mass spectrometer pretreating device, comprises sampling control system, exhaust emission system, discharging of waste liquid system and sample heating system.
Sampling control system: four tunnel sample gas enter pretreating device sample introduction 1 from sampling conduit through sampling probe sampling, and the sample gas flowed out from two-way valve is filtered for the first time through strainer tube 2, flows through de-watering apparatus 4, and through voltage regulation part 3, sample is stabilized in certain pressure.Sample gas enters sample heating system after output filter again fine filtering.
Toxic emission part: flow out sample gas from voltage regulation part 3 bypass and converge to exhaust gas collection block through two logical vent valves, access exhaust system from total exhausr port 7.
Discharging of waste liquid part: the waste liquid during work of pre-treatment instrument in sample gas can in drainage arrangement inner accumulated.The waste liquid gathered reaches certain liquid level, and waste liquid can converge to liquid header 8 by drainage arrangement lower interface automatically, discharges from the outlet of house steward.
Sample heating system: adopt temperature control type electric-heating belt to carry out electrical heating.Temperature carries out closed-loop control by intelligent temperature controller, and control temperature environmentally can require autonomous setting with application.There are heat-insulation layer and metal protection protector in heating system outside.Sample gas after heating is analyzed through out splice going splice access gas mass spectrometer.
Through the process of gas pretreating device, sample gas being made when entering mass spectrometer, reaching the quality being bordering on Standard Gases, guarantee reliability when online analytical instrument system is run for a long time continuously and security.
