Abstract
The utility model discloses a gas purification device which mainly comprises a storage cylinder, purifying material and an air tube, wherein the storage cylinder comprises a cylinder body and a cylinder cover, a baffle plate with through holes is arranged between the cylinder cover and the purifying material, quartz wool is arranged between the baffle plate and the cylinder cover, the purifying material comprises a molecular sieve and allochroic silicagel, and the cylinder body is made of colorless and transparent organic glass. The gas purification device is used in an analytical instrument for determining element content of products in a gaseous state, has a simple structure, is convenient to install, can be mounted in any positions on the analytical instrument, can achieve simultaneous purification treatment for various gases, has a good filtering effect, and can ensure accurate and reliable measurement results.
Description
Technical field
The utility model relates to a kind of gas purification apparatus, is mainly used in to measure under the gaseous state alanysis instrument and equipment of some constituent content in the product.
Background technology
When utilizing coulometry maybe should measure under the gaseous state in the product some element with the light technology, need a certain amount of detected sample gas is delivered in the pyrolysis furnace by carrier gas (as argon gas), be allowed to condition at fully burn in the quantitative oxygen after, enter sensing chamber again, determine its content.The effect of carrier gas is to enter reative cell together with certain flow velocity carrier band gaseous sample to separate, and brings the each several part after separated into sensing chamber again and detects, and flows out sensing chamber's emptying or collection at last, and carrier gas has been carrier band effect and do not play centrifugation.
More or less exist the organic impurities of different sizes in the carrier gas, can react with oxygen after entering in the pyrolysis furnace, influence testing result, cause measurement result inaccurate.Also contain a spot of moisture content in carrier gas and the oxygen in addition, enter detection system after, make the lens surface in the detection system be detained aqueous vapor easily, can influence testing result equally.Therefore, before entering pyrolysis furnace, carrier gas and oxygen all will be through purifying and dehumidification treatments.This just needs a kind of device that purifies and anhydrate, and finishes the preceding preparation of reaction.Generally all buy ready-made filter.The filtration device structure of buying is complicated, inconvenience is installed, and uses restrictedly, and medium is few, and filter effect is bad.
The utility model content
The purpose of this utility model provides a kind of simple in structure, and is easy for installation, and purified treatment is effective, guarantees measurement result gas purification apparatus accurately and reliably.
The technical solution of the utility model is: gas purification apparatus mainly is made of storage cylinder, the tracheae that is contained in the cleaning of substances of storage cylinder inside and is connected the storage cylinder two ends, described storage cylinder is made of cylindrical shell and cover, silicagel pad is arranged between the two, be provided with the baffle plate of band through hole between cover and the cleaning of substances, between baffle plate and the cover quartz wool is housed, described cleaning of substances is molecular sieve and discolour silica gel.
Described cylindrical shell is threaded with cover; Described cylinder material is a colourless transparent resin glass; Described tracheae is a polyfluortetraethylene pipe.
The main medium that the gas purification apparatus that the utility model provides adopts is a molecular sieve.Molecular sieve is a kind of cancellated natural or artificial synthetic chemical substance that has.As cross-link dextran, zeolite etc.As chromatography media the time, can carry out classification to mixture by molecular size and separate.The molecular sieve wettability power is extremely strong and can regenerate.It only allows the diameter molecule littler than the aperture to enter, and therefore the molecule in the mixture can be sieved by size.Store in the cylindrical shell cleaning of substances half be molecular sieve half be discolour silica gel.Molecular sieve is mainly used in purification, and discolour silica gel is mainly used in the situation that moisture content absorbs of observing.The discolour silica gel outward appearance is orange colour or translucent glass shape particle, also has very strong wettability power, and its appearance color can produce the obvious color variation along with the increase of hygroscopic capacity in moisture absorption process.Separate with a baffle plate between molecular sieve and discolour silica gel and the storage cover.The effect of baffle plate is to prevent from that molecular sieve and discolour silica gel particle are retained in to store cylindrical shell and store the silicagel pad place that is used to seal between the cover, cause poorly sealed, thereby leak gas.Store the quartz wool between cover and the baffle plate.The effect of quartz wool is to stop the fine particle of molecular sieve and discolour silica gel to enter the whole system gas circuit.Storing cylindrical shell and storing between the cover has silicagel pad, and sealing is reliable.The storage cylinder material is a colourless transparent resin glass, is beneficial to observation.Be thread connection between storage cylindrical shell and the storage cover, easy to loading and unloading.The polyfluortetraethylene pipe of storage cylinder one end is introduced gas; The polyfluortetraethylene pipe of the other end is derived purified gas, enters into reative cell.
The utility model is simple in structure, and is easy to install, can be assemblied in any position of analysis Instrument equipment, can realize multiple gases purified treatment simultaneously, and good purification guarantees measurement result accurately and reliably.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Referring to accompanying drawing, cylindrical shell 7 and cover 2 that storage cylinder is made material by colourless transparent resin glass constitute, there is silicagel pad 4 at both places of being threadedly engaged with, be equipped with in the cylindrical shell by molecular sieve and each half cleaning of substances of forming 6 of discolour silica gel, be provided with the baffle plate 5 of band through hole between cleaning of substances and the cover, quartz wool 3 is housed between baffle plate and the cover, and polyfluortetraethylene pipe 1 is sealedly connected on the cover at storage cylinder two ends.
Claims (4)
1. gas purification apparatus, it is characterized in that mainly constituting by storage cylinder, the tracheae that is contained in the cleaning of substances of storage cylinder inside and is connected the storage cylinder two ends, described storage cylinder is made of cylindrical shell and cover, silicagel pad is arranged between the two, be provided with the baffle plate of band through hole between cover and the cleaning of substances, between baffle plate and the cover quartz wool is housed, described cleaning of substances is molecular sieve and discolour silica gel.
