The invention provides a hydrogen-peroxide high-efficiency utilization method and apparatus for desulphurization and denitration of low-temperature flue gas. According to the method, hydrogen peroxide is fed in the form of gas in the process of desulphurization and denitration of low-temperature flue gas via hydrogen peroxide. The apparatus comprises a hydrogen peroxide storage tank, a feed pump, a flue and an absorbing tower. The apparatus is characterized in that hydrogen peroxide is converted to a gaseous state after treatment by a device for feeding liquid hydrogen peroxide after direct heating and vaporization of liquid hydrogen peroxide, or a device for feeding hydrogen peroxide after bubbling of hot carrying gas in hydrogen peroxide, or a device for feeding hydrogen peroxide carried by hot carrying gas or a device for feeding atomized hydrogen peroxide carried by hot carrying gas; the gaseous hydrogen peroxide then enters the flue; and the gaseous hydrogen peroxide and hydroxyl radicals therein are used for desulphurization and denitration reactions. The method and apparatus provided by the invention changes a conventional liquid-gas mixed reaction into a gas-gas mixed reaction. Compared with liquid hydrogen peroxide, more hydroxyl radicals can be produced through decomposition in the process of vaporization of hydrogen peroxide, so the utilization rate of hydrogen peroxide and the removal rate of NOx are improved, and the usage amount of hydrogen peroxide is reduced.

The invention discloses a power supply device of a vacuum pipeline train and the vacuum pipeline train. The power supply device comprises a hydrogen-oxygen fuel cell which comprises an electrolyte layer, and a first electrode and a second electrode which are respectively arranged on two sides of the electrolyte layer, the first electrode and the second electrode are respectively connected to two ends of a load and used for supplying power to the load of the vacuum pipeline train; a first interface is formed in the outer wall, close to the first electrode, of the hydrogen-oxygen fuel cell, thefirst interface is used for allowing oxygen to flow in, a second interface is formed in the outer wall, close to the second electrode, of the hydrogen-oxygen fuel cell, and the second interface is used for allowing hydrogen to flow in; and a third interface is used for discharging water in the hydrogen-oxygen fuel cell. According to the vacuum pipeline train, the hydrogen-oxygen fuel cell can be used for supplying power to power equipment of the vacuum pipeline train, the requirement for heat loads in the train can be met through the refrigerating capacity of liquid oxygen and liquid hydrogen,in addition, water produced through fuel reaction can be used in carriages, and the vacuum pipeline train has important significance in energy conservation and environmental protection.
