When being always zero, then it may determine that in the water vapour and be not released into CO.
The detection method of on-condensible gas in a kind of steam above-mentioned, the quantitative detecting method include keeping being passed through tank body dress
The water vapour micro-positive pressure discharge set makes the gas in tank device without accumulation, so that the first quadrature tube normal pressure is sucked vapor, rely on
The internal pump of gas-detecting device does power, while condensing water vapour, air balance sucking, made up in time because steam is cold
It is solidifying and the flow of vacancy, two kinds of fluids are converted, but front and back gas CO concentration is constant；When the measured value number of gas-detecting device
When value stablizes constant, measured value, the concentration of CO as in steam are read.
When using qualitative checking method above-mentioned, suitably increase the discharge amount of steam to be measured, the first quadrature tube is suitably close
Steam outlet increases the soakage of steam, reduces the amount of filling into of outside air.When water vapour is in stainless steel bottle body or vial
When being cooled to water in body, fixed gas is in stainless steel bottle body or the intracorporal upper gaseous phase spatial summation of vial in water vapour.If
If sealing in CO in steam, CO is accumulated in stainless steel bottle body or glass body internal upper part gas-phase space, then sucks gas detection
Device, just start gas washing bottle stainless steel bottle body or the intracorporal original gas of vial be air, CO value be 0, about several seconds
Afterwards, CO value can gradually increase, and can exceed instrument range.If the depths steam Pai Kou is inserted into suction inlet one end of the first quadrature tube, can
It can be accumulated as pure conversion gas or water-gas, the CO of 20%-40%.If not sealing in CO in steam, though fixed gas how
Accumulation, gas-detecting device will not show numerical value.So when long-time detects, a large amount of steam sample introductions detect the gas of CO
The reading of detection device is zero always, then can determine to seal in CO without leakage in steam at this for certain.The qualitative side
Method has accumulation enlarge-effect, can capture the micro CO being released into, can accurately determine whether leakage.But accurately to know
The ratio of contained CO in steam, that is, conversion gas or water-gas seal in the leakage severity of steam, by monitoring the data
To judge degree of danger, selection proper moment parking maintenance, then quantitative detecting method will be introduced.
When using quantitative detecting method above-mentioned, steam valve is adjusted, controls water vapour uniform discharge, adjusts tank body branch
Frame, the air-flow micro-positive pressure for making tank device turn back up.The tube body fixed frame for adjusting tank device, makes the first quadrature tube nozzle
Suck the water vapour of normal pressure.While water vapour is cooling, the volume that water vapour is available is filled by air balance.Air fills into
It also occurs at the suction inlet of the first quadrature tube and enters together with water vapour, unique power source is exactly the gas detection of end
The internal pump of device.By adjusting the tube body fixed frame of tank device, to select the first quadrature tube suitably to suck position, control
Sucking water vapour is normal pressure, and the sucking continual and steady by the internal pump of gas-detecting device can form the stable state of measurement,
It is exactly the self-consistent stable state of CO concentration, measurement result can be stabilized to the volume of CO in a fixed value, that is, water vapour
Compare content.This measurement process mainly adjusts the first right angle nozzle sucking position and gas of turning back by the variation of detector value
Stream, makes measured value be stabilized to a definite value, is adjusted by definite value, reach definite value and illustrate that stable state has been established.Actual measurement process
It was found that the first right angle nozzle should not be close to moisture discharge nozzle, measured value as long as discharge of steam not cross large impact suction line
It is easy to be stabilized to a definite value, it is not tight to the adjusting requirement of the first right angle nozzle position and vapor stream, because tank body is turned back
Steady air current, air-flow is actively sucked by gas-detecting device internal pump in pipeline, and water seal does not influence filling into time for air shallowly,
The continuity of air-flow is not influenced.When using on-line measuring device, after adjusting properly for the first time, fixed steam discharges valve position, Gu
Tank device and the first quadrature tube position are determined, without adjusting again.
Some methods calculate vapour volume, fixed gas independent measurement by weighing the quality of condensed water.It not only surveys in this way
Amount process is extremely complex, and treatment process introduce miss by a mile.
Apparatus of the present invention are simple, and method is ingenious, practical, and accurately and reliably, there is no erroneous judgements and interference.Effective solution
On-condensible gas can not problem measured directly in steam.Using apparatus of the present invention and method, can timely and accurately detect to let out
The steam source of leakage, and leakage rate can be accurately monitored, leakage detection point and repairing discovery leakage is just blindly stopped comprehensively after are avoided,
Scientific arrangement maintenance is realized, ensure that yield, while by dangerous item station in controlled range.
