such devices are known for generating harmful gases in

air - a useful model p © 15 2IG62. The device contains a pressure vessel, a dispenser, a throttling device, an evaporation device, a carrier gas, a thermostat to limit the influence of temperature among, a compressor, a drying device,

The disadvantage is the generation of one gas.

Also known are calibration ampoules (cylinders) filled with gas of a certain concentrate produced by the Amerschansky company VASVDASH / l 47- catalog fschrs VASNAMSH SM International exhibition Neftegaz, 1995, Moscow, Moscow

The disadvantage is that mixtures send only specific values of gas concentrations that are unregulated.

A known device is a generator (hydrogen fluoride containing a power source, the output of which is connected to an effluent cell made in the form of a mono (poly) cristallic solid-electrolyte ion-conducting element from lanthanum trifluoride doped with a fluoride wire with a platinum anode and a cathode core in the form of a silver in an aqueous solution of sodium fluoride and ash fluoride. / 57 RF patent 2094793 7

| the generator is equipped with a pump, a flow indicator, two adjustable chokes, an output switch, a reference voltage source, two switches, two analog-to-digital converters, two amplifiers, a suction transformer, a voltage converter: to the current source.

The disadvantage is the generation of hydrogen fluoride only.

Known chlorine generator 1rant-GC is designed to generate a variable fixed gp1popriblya chlorine in the air. / USA catalog, appliances and GA, J /

The disadvantage is that it generates only one chlorine.

A device is also known for a dosing gas mixture designed for generating a mixture of either hydrogen chloride or ash ash.

the disadvantage is that it generates only one harmful co-component. / certificate P © liJ 21662 publ. 01.27.02 In IS 3 - 2003, / l§7 “

The task that will be solved by the new design of the plant for testing mixtures - the generation of calibration mixtures of two or three harmful gases, which will allow the analysis of

the presence of other gas for the accuracy and performance of the calibration characteristics of the gas analyzer, to clarify the correlation at the same time, the presence of extraneous gas must be taken into account when operating the gas analyzer in a specific production and the surrounding air.

The prototype of the proposal; the most constructive are the generators of individual gas mixtures L1, L4, L5, LB 7 which create a certain percentage of harmful gas in the air.

A certain gas generator contains a harmful gas dispenser, an impeller for the consumption of diluent gas (air), and controls that allow you to create span gas mixtures of different concentrations of a single gas.

The thrashing constituent is distinguished by the fact that a set of separate gas generators was used, sewerage was provided, an additional gas supply for the caddy of the gas component was added, a common mixer, and clean the shut-off organ.

A general view of the design of the generator of calibration gas mixtures of the RPS is shown in Fig. 1. 1 - a generator of an air gas mixture containing hydrogen chloride, 2 - a generator of air gas gas, containing chlorine, 3 - a flowmeter of an air mixture of layered hydrogen, 4 - a flow chiller, an air mixture of chlorine, 5 - a mixer 11, a common valve, 6 a shut-off valve, a common valve, 7 - 1-piece valves, 8- generator of hydrogen fluoride mixtures, 9- flowmeter of hydrogen fluoride mixture, 8- generator of atzhaka air mixture, 9- flowmeter of mixture with air, 8- fluorine air mixture generator, fluorine mixture flow meter, air generator and it takes control of the gas if its design provides for controls that allow you to create certain predetermined gas concentrates in the air, Kshshigl generator 1,2,8, a certain set gas concentration in BQgyxe is created during calibration when calibrating, which flows through channel 7 through a flow meter with either 4 msw 9 or 9 into the common mixer 5 and through the outlet 7-: norgo |: “valve 6 at the input of the analyzer under test, which had to be tipped off, to experience the influence of their {gas mixtures on the gauge thickness for a specific gas The specified co-concentrations of gas mixtures are generated by acting on the controls of each of the generators of a certain gas (W 2t 8 8, 8) the Koropix stream is mixed into a common gas mixture stream in barely 5.

cokhleksiiii containing combinations of controlled generators of various gas mixtures: hydrogen chloride flare, ashliak, fluorine, hydrogen fluoride, which makes it possible to reveal the effect of gas mixtures on the accuracy of the percentage determination of each gas when they are taken together in the mixture when gas analyzers are calibrated. The proposed generator is new, so such a design: there is no space in the technique. The proposed generator is applicable in industry for calibration of gas analyzers, for the creation of variable gas mixtures.
