Description
Technical field
A kind of method that the present invention relates to quick measurement hydrogen, especially relates to a kind of raising and produces hydrogen and carbon monoxide
The hydrogen of device analyzes the method for detection rates.
Background technology
HYCO device supplies CO product by pipeline downstream client, and the parameter and indexes of contract requirement CO product is as follows:
CO product
Vppm:10-6(by volume)；Vppb=10-9(by volume)
Device should monitor H20, CH4, H2 and CO content in CO product.Wherein H2 analyser should have Redundancy Design, and three take
Two interlockings, band fast loop, interlocking value should be set to 10000Vppm, and alarming value is set to 1000Vppm.CH4 analyser should have redundancy,
Band fast loop, range to 100Vppm, alarming value 11Vppm.This system should be entirely prevented from the CO product of H2 content overproof and enter
Client's CO pipe network system.
In the prior art, do H2 content in CO product and surpass the testing time of 10000ppm interlocking close CO products export valve
Being 100 seconds, this test result does not meets the safety requirements of client, although through test of many times and the change of test method, still
Do not shorten the time of interlocking action.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and provide a kind of and improve response speed
The hydrogen producing hydrogen and the carbon monoxide device method of analyzing detection rates.
The purpose of the present invention can be achieved through the following technical solutions:
Improving and produce the method that the hydrogen of hydrogen and carbon monoxide device analyzes detection rates, the method is used for detecting CO and produces
The content of water, methane, hydrogen and carbon monoxide in product, the deferent segment at detection device is provided with hydrogen analyser, this hydrogen
Analyser connects sampling pipe, and subsequent pipeline is provided with rapid cut-off valve, and described sampling pipe is the probe tube of diameter 6mm,
After utilizing the sampling of this probe tube, test through hydrogen analyser, when detecting that hydrogen content reaches alarming value, close in 40s
Rapid cut-off valve on subsequent pipeline.
Described hydrogen analyser is provided with three, and three hydrogen analysers are that two from three is interlocked and with fast loop.
The interlocking value of described hydrogen analyser is 10000Vppm.
The alarming value of described hydrogen analyser is 1000Vppm.
Compared with prior art, the invention have the advantages that
(1) storage of sample gas in probe tube is calculated by formula, after transformation: before transformation=1: 4, this means that online
The response of analyser can improve 4 times；
(2) again testing after transformation is good, the result action time is 26 seconds, passes through device to test, and obtains CO product
Supply after the accreditation of product client on schedule.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.
Embodiment
Improving and produce the method that the hydrogen of hydrogen and carbon monoxide device analyzes detection rates, the method is used for detecting CO and produces

Not Wei 3-1711AT050.1,3-1711AT050.2,3-1711AT050.3, above-mentioned hydrogen analyser connect sampling pipe, follow-up
Pipeline is provided with rapid cut-off valve, and hydrogen analyser is interlocked and with fast loop, hydrogen analysis with Redundancy Design, two from three
The interlocking value of instrument is 10000Vppm, and alarming value is 1000Vppm.Make the probe tube of original a diameter of 12mm into diameter 6mm
Probe tube, because the sample gas sample size of in-line analyzer is a fixing amount, the factor of the response time of that impact analysis instrument is only
There is the process pipe amount to the sample gas in the sampling line between analyser.After utilizing the sampling of this probe tube, through hydrogen analyser
Test, when detecting that hydrogen content reaches alarming value, closes the rapid cut-off valve on subsequent pipeline in 40s.
In the present embodiment, the test result that the hydrogen analyser of 3-1711AT050.1 is made 26 seconds, 3-1711
The test result that the hydrogen analyser of AT050.2 is made 20 seconds, the test result that the hydrogen analyser of 3-1711AT050.3 is made
21 seconds.
