a natural gas mixer

Abstract

The invention relates to a natural gas mixer which comprises an outer shell, an inner chamber and a gas chamber, wherein the inner chamber is coaxially arranged in the outer shell; the gas chamber is arranged in the inner chamber; the inner chamber has a hollow waist-shaped structure; the inner chamber comprises an air inlet part, a mixing part, a mixed gas outlet part which are successively communicated with each other from bottom to top; a natural gas pressure-stabilizing chamber is encircled by the air inlet part, the mixing part, the mixed gas outlet part and the inner wall of the outer shell; the gas chamber comprises a connecting plate and a gas chamber gas-inlet pipe corresponding to the plate; the outer end of the gas chamber gas-inlet pipe penetrates through a connecting hole of the gas chamber and then extends into the natural gas pressure-stabilizing chamber; a cross section of the gas chamber gas-inlet pipe has a water drop shaped structure with wide top and narrow bottom; an anti-tailing structure is arranged an upper arc part of the outer end. The natural gas mixer has the advantages of larger space of the pressure-stabilizing chamber, smooth mixed gas flow, high mixing uniformity, better mixing effect and higher stability.

Description

technical field [0001] The invention relates to a natural gas engine facility, in particular to a natural gas mixer, which is particularly suitable for increasing the space of a pressure stabilizing chamber, ensuring smooth flow of mixed gas, and improving mixing uniformity and mixing effect. Background technique [0002] The shortage of resources and environmental pollution make the country give strong support to the development of new energy power. As a clean energy, natural gas has been widely used in automobile, engineering and other industries. According to market research data, the market demand for natural gas engines is huge, coupled with the country's subsidy policy for new energy vehicles, people are more fond of new energy vehicles. Considering the long-term development, major car companies have increased their investment and increased their technical reserves for new energy vehicles. After years of hard work, natural gas engines have gradually matured and their ...
