Abstract
The utility model relates to an apparatus for removing water vapour. The utility model comprises a slot body, a slot cover which is fixedly arranged on the slot body, and a gas permeable film which is arranged between the slot body and the slot cover, only permeates gas and does not permeate water or water vapour. The slot cover is provided with a hydride gas outlet hole. One side of the slot body which is contacted with the slot cover is provided with a waste liquid tank. The side of the slot body is provided with a mixture gas inlet and a waste liquid outlet. The utility model can be used for the hydride generation systems of various atomic spectrometers (comprise AAS, AFS and AES), and is arranged between a regular gas-liquid segregator and an atomizer, and can also be used for other mixture gas separation with water vapour. Water vapour can not enter into the atomizer at all under the function of the gas permeable film. Therefore, the utility model increases instrumental signal-to-noise ratio, and effectively improves instrumental detection lower bound.
Description
Background technology
The utility model relates to a kind of moisture separator, specifically, relates to a kind of device of removing steam.
Technical field
Hydride generation method is widely used in atomic spectroscopic analysis (comprising AAS, AES and AFS).It is to utilize the acid-base neutralization reaction, makes tested element generate gaseous hydride, carries it into atomizer by carrier gas, and the waste liquid that generates with reaction effectively separates.But carry in the process of gaseous hydride in carrier gas, taken away steam simultaneously.Steam enters atomizer with gaseous hydride, is one of principal element of jitter.
" secondary gas-liquid separation " or " three grades of gas-liquid separations " or the like arranged in the prior art, main design philosophy, be with steam after carrying distance through one section, the moisture that condenses is from coming out, but still has the steam that is not condensed to enter atomizer.
The utility model content
The purpose of this utility model provides a kind of setting that is used for the removal steam of hydride generating system.
The device of removal steam described in the utility model, comprise cell body, be fixedly mounted on the groove lid on the cell body and be arranged on cell body and the groove lid between, the ventilated membrane of a permeable watertight and steam, described groove lid has the hydride gas venthole, described cell body has waste liquid tank with the one side that the groove lid contacts, and has gaseous mixture inlet and waste liquid outlet in the side of cell body.
The contact-making surface that described groove is placed on cell body be the plane or have with cell body on the corresponding groove of waste liquid tank.
The lower curtate of described waste liquid tank favours the last plane of cell body, and described gaseous mixture inlet is arranged on the high side of bottom land, and the waste liquid outlet is arranged on the low side of bottom land.
The inlet end of described venthole is help gas communication tubaeform.
Described gaseous mixture inlet is arranged on the same side with the waste liquid outlet or is arranged on the different sides.
Device described in the utility model can be used for all kinds of atomic spectrographs hydride generating system of (comprising AAS, AFS and AES), is installed between conventional gas-liquid separator and the atomizer, also can be used for the mixed gas separation that other have steam.Under the effect of ventilated membrane, steam can not enter atomizer fully, thereby has improved instrument signal to noise ratio, has effectively improved the lower limit that detects of instrument.
Description of drawings
Fig. 1 is the schematic representation of apparatus of removal steam described in the utility model.
The specific embodiment
Atomic spectroscopic analysis adopts hydride generation method usually, by reacting with acid-base neutralization, make tested element generate gaseous hydride, carry it into atomizer by carrier gas, but carry in the process of gaseous hydride in carrier gas, taken away steam simultaneously, the gaseous hydride that has steam of this moment, for sake of convenience, be called gaseous mixture.
Below in conjunction with accompanying drawing, the device of removal steam described in the utility model is elaborated.
Referring to Fig. 1, the device of removal steam described in the utility model comprises cell body 3, be fixedly mounted on the groove lid 1 on the cell body 3 and be arranged on cell body 3 and groove lid 1 between, the ventilated membrane 2 of a permeable watertight and steam.Described groove lid 1 can be used bolt, screw or other methods commonly used with the fixing of cell body 3.
The described groove lid 1 of going up has hydride gas venthole 4, being screwed hole shown in Fig. 1, also can be a through hole, and this Kong Yuyi pipeline is communicated with, discharging hydride gas, with the contact-making surface of cell body 3 can for the plane or have with cell body 3 on waste liquid tank 5 corresponding grooves.Described cell body 3 has waste liquid tank 5 with groove lid 1 one side that contacts, and the lower curtate of this waste liquid tank favours the last plane of cell body 3, and promptly the degree of depth of waste liquid tank 5 is dark on one side, on one side shallow, have gaseous mixture inlet 6 and waste liquid outlet 7 in the side of cell body 3.Described gaseous mixture inlet 6 is arranged on the high side of bottom land, and waste liquid outlet 7 is arranged on the low side of bottom land, helps gaseous mixture with steam like this in this retention period, and water vapor condensation is the discharge behind the water.
Described gaseous mixture inlet 6 and waste liquid outlet 7 can be arranged on the same side of cell body 3 according to the needs of the installation site of integral device, also can be arranged on the different sides.
The air inlet of described venthole 4 can be for helping the tubaeform of gas communication.
During work, gaseous mixture inlet 6 links to each other with the hydrogenation gas-liquid separator outlet of routine, hydride gas outlet 4 is communicated with atomizer, the carrier gas and the steam-laden gaseous hydride of conventional gas-liquid separator output enter gaseous mixture inlet 6, and carrier gas and gaseous hydride see through ventilated membrane, enter atomizer through hydride gas outlet 4, and steam can not see through ventilated membrane, is condensed in the waste liquid tank 5, discharges through waste liquid outlet 7.
