Air distribution system capable of realizing stable combustion of hydrogen

Abstract

The application discloses an air distribution system capable of realizing the stable combustion of hydrogen. The air distribution system comprises a hydrogen inlet device, a combustion-supporting gasinlet device, an air mixed control device and a combustion device, wherein the hydrogen inlet device and the combustion-supporting gas inlet device are separately connected with the combustion deviceand the air mixed control device; the combustion-supporting gas inlet device comprises an air inlet sub-device and an oxygen inlet sub-device; the air inlet sub-device comprises an air inlet plate anda supercharger connected with each other; the oxygen inlet sub-device comprises an oxygen storing tank and a second pressure reducing valve connected with each other; the supercharger and the secondpressure reducing valve are separately connected with the combustion device through a second pipeline; a mixing bottle is arranged at one end of the second pipeline; and a second barometric instrumentis arranged between the second pressure reducing valve and the mixing bottle. The air mixed control device controls the combustion-supporting gas inlet device to provide enough oxygen for the safetycombustion of hydrogen through the pressure of the hydrogen in the hydrogen inlet device, and transmits the mixed gas to the combustion device, so that the hydrogen combusts stably in the combustion device.

Description

technical field [0001] The present application relates to the application field of hydrogen energy, in particular to a gas distribution system for stable combustion of hydrogen. Background technique [0002] Hydrogen is an extremely flammable gas with an ignition point of only 574°C. Stable combustion of hydrogen and air produces only water without any harmful gas, so hydrogen energy will become the ultimate energy source for human development. At present, hydrogen cannot be widely promoted because hydrogen has a low density and is easy to diffuse in the air. It can only burn when it enters the explosion zone. However, it is not allowed to diffuse too much, causing deflagration or explosion. Therefore, it is necessary to ensure the ratio of hydrogen to oxygen to prevent incomplete combustion or the hydrogen content is lower than the lower limit of the explosion limit, and cannot be burned. In addition, it is necessary to limit the pressure of hydrogen and combustion-suppor...
