The gas flow of reaction is controlled；Meanwhile, the heat that reaction produces is taken out of catalytic bed more so that
The operating temperature of catalytic bed is unlikely to too high；Described catalytic bed structure provides power to only rely on self without outside
The spontaneous operation of heat that during work, gas reaction produces, belongs to chemical reaction device technical field.
Background technology
Hydrogen is a kind of flammable explosive gas, and aerial content reaches certain concentration will exist blast
Danger.Nuclear power station will produce a large amount of hydrogen when there is some accident in containment, exist for eliminating nuclear power station
The hydrogen discharged during accident condition, protection containment avoids the danger of hydrogen explosion, and existing nuclear power station is universal
Use hydrogen set composite to eliminate hydrogen, wherein, be included under major accident state the passive hydrogen used
Gas set composite.This kind of hydrogen set composite provides the energy without outside, relies on and is arranged in described device bottom
Catalytic bed by hydrogen and oxygen composition generation water and release heat, the hot-air after described device internal-response
There is density contrast from the surrounding air outside described device owing to temperature is different, described device case has one
Fixed height, under gravity, reacted hot-air rises and from described dress inside described device
Top set portion discharges, and the air containing hydrogen gas around described device enters catalytic bed from described bottom of device and reacts,
So go round and begin again, spontaneous operation.
According to its operation principle, the air inflow of existing passive hydrogen recombination device is along with Hydrogen in Air concentration
Increase and increase, this will cause when higher density of hydrogen, and the temperature within device catalytic bed can be higher
The even up to firing temperature of hydrogen, originally in order to prevent the hydrogen set composite of hydrogen explosion from may become on the contrary
For causing the incendiary source of hydrogen explosion or burning.Therefore, when higher density of hydrogen, existing passive hydrogen
Gas set composite has certain potential safety hazard.
