Embodiment 1

[0050] like figure 1 As shown, the passive hydrogen recombiner test system mainly includes a gas mixing tank 6, a reaction vessel 9 and a sampling unit 12 connected in sequence, and a steam generator 7 is also connected to the inlet end of the reaction vessel 9.

[0051] In order to ensure the accuracy of the detection of the sampling unit, a water eliminator 11 is provided between the reaction vessel 9 and the sampling unit 12, which can remove the reacted water; There is also a flow controller 5 between them; it is convenient for the sampling unit 12 to test the hydrogen concentration of the outlet gas; and the reaction vessel 9 is provided with a safety valve 10 .

[0052] In order to reliably prevent the propagation of flashback and explosion waves, and to quickly discharge the gas into the atmosphere, and to automatically cut off the gas source, a flashback arrestor is arranged between the gas mixing tank 6 and the reaction vessel 9 3; and in order to ensure the one-way ...

Embodiment 2

[0072] Use the passive hydrogen recombiner test system and test method in embodiment 1 to detect the stable reaction performance of the recombiner, and the detection method is as follows:

[0073] When testing a recombiner, at a total intake flow rate of 650m 3 Under the conditions of temperature 350°C and pressure 0.65MPa, 1~4vol% hydrogen and the remaining proportion of oxygen are passed into the reaction vessel. After a period of time, the reaction is stabilized. The same, the hydrogen concentration is also detected by the sampling unit, and the recombination hydrogen amount and recombination efficiency under the detection of this item are calculated through the flow rate displayed on the flow controller. When the recombination hydrogen amount reaches 2.4kg / h or more, the recombination efficiency Reaching more than 90%, the compounder is a qualified product.

[0074] When testing two compounders at the same time, the only difference from testing one compounder is that the ...

Embodiment 3

[0076] Use the passive hydrogen recombiner test system and test method in Example 1 to detect the repeatability of the recombiner. This test mainly examines the repeatability of the recombiner hydrogen content and recombination efficiency in multiple tests to evaluate Reliability and service life of the recombiner. Its detection method is as follows:

[0077] The specific steps of this detection method are the same as the stable reaction performance detection steps and parameters, the only difference is that the test is carried out 5 times in a cycle. When the recombination hydrogen amount of a single recombiner reaches more than 2.4kg / h in each test, the recombination efficiency reaches 90%. Above, it shows that the repeatability of the compounder is qualified.

[0078] When testing two compounders at the same time, the only difference from testing one compounder is that the total intake flow is 1500m 3 / h; when detecting three compounders at the same time, the difference f...

Abstract

The invention discloses a test system for a passive hydrogen recombiner, and solves the problem that a system for testing the complete machine of a passive hydrogen recombiner is unavailable in the prior art. The test system mainly comprises a mixed gas tank, a reaction vessel and a sampling unit which are connected in sequence, wherein the reaction vessel is communicated with a water vapor generator. The invention also provides a test method of the test system for the passive hydrogen recombiner. The test system provided by the invention has the advantages of simple structure, convenience in operation and suitability for popularization and application.

Description

technical field [0001] The invention relates to a testing method, in particular to a testing method of a passive hydrogen recombiner testing system. Background technique [0002] The internal space of the containment vessel of a nuclear power plant is about tens of thousands of cubic meters, and dozens of passive hydrogen recombiners are distributed inside. It is very difficult to perform performance tests on all the dozens of recombiners. [0003] There is no device in my country that can test the complete passive hydrogen recombiner, and there are only a small number of devices for research. The largest device can be used to study samples equivalent to 1 / 6 the size of the complete recombiner. At present, my country's Nuclear Safety Administration and Energy Administration are formulating the "Nuclear Safety Plan" and "Nuclear Power Safety Plan" after the Fukushima nuclear accident in Japan, which will make stricter regulations on the passive hydrogen recombiner used in the...
