Problems solved by technology

[0003] According to the Chinese patent with the application number CN201210056880.5 - the gas engine intake flashback preventer, the current gas vehicle engine intake system is rarely equipped with a special flashback preventer, and a small part of it is equipped with a flashback preventer. The anti-backfire effect is not obvious, the service life is short, and the air intake resistance is increased, resulting in a decrease in engine power, which greatly affects the application and promotion of gas vehicles
[0004] In the prior art, the gas generator set needs a mixer to mix the gas and air when it is working, but most of the current related mixers cannot disperse the gas and air at the same time, so that the mixing of the two is simply passed into a space , the mixing rate of the two is very low, so it is prone to the phenomenon that it cannot be ignited after multiple ignitions

Abstract

The invention discloses a novel anti-backfire gas mixer for a gas generator set, and belongs to the technical field of gas generator sets. The novel anti-backfire gas mixer comprises an outer conveying pipe, an inner conveying pipe is clamped and fixed in the outer conveying pipe, the outer conveying pipe and the inner conveying pipe are sleeved with an outer sleeve box, a first inner chamber is annularly distributed between the outer conveying pipe and the inner conveying pipe, and a second inner chamber is formed in the inner conveying pipe. A sealing partition plate is fixedly sealed at the top of the first inner chamber, at least four inclined conveying pipes for conveying air towards the inner side in a scattered mode are installed on the sealing partition plate in a circumferential array mode, each inclined conveying pipe is formed by welding a pipe base and an arc-shaped cap, and a plurality of air outlets distributed in a circumferential array mode are formed in the outer wall of each arc-shaped cap. An annular blocking piece which shrinks upwards and inwards is welded to the inner wall of each arc-shaped cap, and an arc-shaped backflow cavity communicated with the air outlets is formed in each arc-shaped cap through the annular blocking piece. According to the novel anti-backfire gas mixer for a gas generator set, the mixing rate is higher, and the ignition efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of gas generator sets, and in particular relates to a novel anti-backfire gas mixer for gas generator sets. Background technique [0002] Gas generator set is a new type of generator set developed to meet the world's environmental protection requirements and the new market environment. [0003] According to the Chinese patent with the application number CN201210056880.5 - the gas engine intake flashback preventer, the current gas vehicle engine intake system is rarely equipped with a special flashback preventer, and a small part of it is equipped with a flashback preventer. The anti-backfire effect is not obvious, the service life is relatively short, and the intake resistance is increased, resulting in a reduction in engine power, which greatly affects the application and promotion of gas vehicles.
