Title:
GAS MIXER
Document Type and Number:
WIPO Patent Application WO/2020/133355
Kind Code:
A1
Abstract:
A gas mixer, comprising a mixer housing (1) and a mixer core (2). The mixer core (2) comprises a fuel gas core (21) and an EGR core (22); the fuel gas core (21) is internally provided with two fuel gas injection tubes (3) which intersect, and four EGR injection tubes (4, 5) are provided in the EGR core (22) and form a Swiss cross-shaped intersecting EGR mixing core. The fuel gas mixing core structure and the EGR mixing core structure of the gas mixer are both designed as a Swiss cross-shaped intersecting combined formation, so that both fuel gas and EGR exhaust gas may be ejected from multiple injection holes of a radial injection pipe and fill the cross section of the mixer core (2), which further improves the uniformity of the fuel gas and EGR exhaust gas entering the mixer core, and combines relatively low pressure loss with relatively high working reliability. Meanwhile, the sensitivity of a mixing effect of the mixer guiding downstream pipelines is reduced.
