Abstract
The invention discloses a gas purifying device which mainly consists of a storage cylinder, a purification substance and an air pipe. The storage cylinder consists of a cylinder body and a cylinder cover, a baffle plate with a through hole is arranged between the cylinder cover and the purification substance, quartz wools are arranged between the baffle plate and the cylinder cover, the purification substance is molecular sieves and allochroic silicagel, and the cylinder body is a colorless and transparent organic glass material. The gas purifying device is applied to an analytical instrument for measuring certain element content in product in the gas state, has a simple structure, is convenient to install, can be assembled at any position of an instrument, can purify a plurality of gases simultaneously, is good in purifying effect and can ensure the accuracy and reliability of the measuring result.
Description
Technical field
The present invention relates to a kind of gas purification apparatus, be mainly used in and measure under the gaseous state alanysis instrument and equipment of some constituent content in the product.
Background technology
Utilize coulometry or use optical tech when measuring under the gaseous state in the product some element; Need a certain amount of sample gas to be detected is delivered in the pyrolysis furnace through carrier gas (like argon gas), be allowed to condition at fully burn in the quantitative oxygen after; Get into sensing chamber again, determine its content.The effect of carrier gas is to get into 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 the entering pyrolysis furnace is interior, influence testing result, cause measurement result inaccurate.Also contain a spot of moisture content in carrier gas and the oxygen in addition, after the entering detection system, make the lens surface in the detection system be detained aqueous vapor easily, can influence testing result equally.Therefore, before getting into pyrolysis furnace, carrier gas and oxygen all will pass through and purify and dehumidification treatments.This just needs a kind of device that purifies and anhydrate, and accomplishes the preceding preparation of reaction.Generally all buy ready-made filter.The filtration device structure of buying is complicated, inconvenient installation, uses restrictedly, and medium is few, and filter effect is bad.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, easy for installation, purified treatment is effective, guarantees measurement result gas purification apparatus accurately and reliably.
Technical scheme of the present invention is: gas purification apparatus mainly is made up of storage cylinder, the tracheae that is contained in the inner cleaning of substances of storage cylinder and is connected the storage cylinder two ends; Said storage cylinder is made up 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 be housed, said cleaning of substances is molecular sieve and discolour silica gel.
Said cylindrical shell is threaded with cover; Said cylinder material is a colourless transparent resin glass; Said tracheae is a polyfluortetraethylene pipe.
The main medium that gas purification apparatus provided by the invention adopts is a molecular sieve.Molecular sieve is a kind of cancellated natural or artificial synthetic chemical substance that has.Like cross-link dextran, zeolite etc.As chromatography media the time, can carry out fractionated to mixture by molecular size.The molecular sieve wettability power is extremely strong and can regenerate.It only allows the diameter molecule littler than the aperture to get into, and therefore can the molecule in the mixture be sieved by size.Store in the cylindrical shell cleaning of substances half the be molecular sieve half the 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 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 get into 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 present invention 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 a structural representation of the present invention.
The specific embodiment
Referring to accompanying drawing; The cylindrical shell 7 that storage cylinder is made material by colourless transparent resin glass constitutes with cover 2; Both have silicagel pad 4 by the screw thread joint, are equipped with in the cylindrical shell by molecular sieve and each half cleaning of substances of forming 6 of discolour silica gel, are 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.
