Abstract

The invention provides a multi-pipe gas-state fuel mixer using in-pipe mixers. The multi-pipe gas-state fuel mixer comprises a shell; a center fuel channel, a peripheral fuel channel and an annular air channel are coaxially formed in the shell in the radial direction; the peripheral fuel channel comprises a peripheral fuel conveying pipe, and multiple peripheral fuel nozzles peripherally arranged and connected to the outer wall of the peripheral fuel conveying pipe; the annular air channel comprises a peripheral air channel and a center air channel; a peripheral cyclone device and a center cyclone device are respectively arranged in the peripheral air channel and the center air channel; the peripheral cyclone device comprises multiple pipes uniformly distributed in the peripheral direction; and multiple in-pipe mixers are axially distributed in the pipes. Through a multi-pipe premixing mode of the peripheral channel and application of the in-pipe mixers, the oil-gas mixing is uniform, and the pollution emission is reduced.

Description

technical field [0001] The invention relates to a gas mixing device, in particular to a multi-tube gaseous fuel blender using an in-tube mixer. Background technique [0002] With the development of society, people have higher and higher requirements for efficient use of energy and environmental protection. However, conventional fossil fuels still occupy a considerable proportion, and the carbon dioxide and pollutant emissions they produce have caused great environmental pressure. Therefore, people advocate energy conservation and emission reduction. On the one hand, new energy sources such as solar energy and wind energy are developed to reduce carbon emissions; On the one hand, it is hoped that the fuel utilization of fossil fuels can be more efficient and the pollution emissions will be lower. However, new energy sources such as solar energy and wind energy are not suitable for large-scale promotion due to their natural characteristics and current technical limitations. ...
