Mixer

Abstract

The invention discloses a mixer, comprising a mixer body and a flow guide body, wherein the flow guide body is arranged between an air inlet of the mixer body and a mixed gas outlet, and comprises a flow guide ring and a flow guide post which is arranged in the flow guide ring; a plurality of natural gas orifices for jetting a natural gas into the mixer body are formed in the flow guide ring and the flow guide post. According to the mixer disclosed by the invention, the mixing uniformity is about 95%, and is greatly improved; the air intake uniformity of an engine is improved; the power of the engine is improved; various faults caused by uneven mixing of air and natural gas are reduced; consumption of the natural gas is lowered under the same output power; the energy source is saved; the mixer is relatively economical and applicable.

Description

technical field [0001] The invention belongs to the field of gas engine mixed gas, and in particular relates to a mixer. Background technique [0002] The mixer in the gas engine is to fully mix natural gas and air to form a combustible mixture and supply it to the engine. The mixer should be able to fully and evenly mix air and natural gas. [0003] Such as Figure 7 ~ Figure 9 As shown, the patent number is "ZL201220347243.9" and the patent name is "Mixer Assembly". The disclosed mixer includes a mixer body, a mixer core arranged in the mixer body and four teardrop-shaped Branch pipe, when the air enters the mixer, according to the principle of kinematics, the air passes through the surface of the teardrop-shaped branch pipe to generate a disturbance, which can make the gas coming out of the small hole of the core more uniformly mixed. [0004] If the air and gas are completely mixed uniformly, the mixing uniformity should be 1. Through analysis and calculation, the mixi...

AI Technical Summary

Problems solved by technology

[0004] If the air and gas are completely mixed uniformly, the mixing uniformity should be 1. Through analysis and calculation, the mixing uniformity of the mixer of the above patent is about 76%, which is still far from complete mixing, but the air and gas are not mixed uniformly. It is easy to cause failures such as unstable idling speed, carbon deposits, insufficient combustion, and fatigue of gas engines. Now there is an urgent need for a mixer with higher mixing uniformity and better mixing effect.
