Abstract

The invention provides self-powered hydrogen gas processing equipment. The self-powered hydrogen gas processing equipment comprises a heat-power conversion device, a catalytic compounding device, a high-voltage power supply generation circuit and a hydrogen gas ignition device, wherein the heat-power conversion device is provided with a low-temperature side and a high-temperature side, and a containing chamber is defined between the low-temperature side and the high-temperature side; a heat-power conversion module is arranged in the containing chamber; the catalytic compounding device is used for catalyzing hydrogen gas and oxygen gas flowing through the device so as to be subjected to compounding reaction to generate water and heat; the catalytic compounding device generating the heat is arranged at the high-temperature side and is used as a heat source; the high-voltage power supply generation circuit is electrically connected with the heat-power conversion device and is used for converting low voltage generated by the heat-power conversion device to high voltage; high-voltage power generated by the high-voltage power supply generation circuit is supplied to the hydrogen gas ignition device for carrying out hydrogen gas ignition. The invention provides the nuclear power station containment with the self-powered hydrogen gas processing equipment. With the adoption of the technical scheme provided by invention, the independence of the hydrogen gas processing equipment on an external power supply under an accident condition can be solved and the passive control on hydrogen gas risks in the containment is realized.

Description

technical field [0001] One embodiment of the present invention relates to hydrogen processing equipment, particularly hydrogen processing equipment for processing hydrogen in large vessels. Background technique [0002] After a dehydration accident and a fusion reactor accident in a nuclear power plant, a large amount of hydrogen will be produced due to the zirconium water reaction, the radiation decomposition of water, and the reaction between the core melt and concrete, and the hydrogen production rate is fast and the hydrogen concentration is high (hydrogen concentration It will reach 10% or even 18%, about 1350kg of hydrogen can be produced in the first 7 hours of the accident, and the highest hydrogen production rate can reach 2kg / s), and the temperature and pressure in the containment vessel will increase accordingly. [0003] Due to the long process of the serious accident, judging from the time point of the hydrogen explosion in the Fukushima accident, the hydrogen e...
