Description
Technical field
The utility model relates to natural gas engine technical field, particularly relates to a kind of air inlet mixer.
Background technique
Mixer is important parts in natural gas engine, its effect is exactly by air and combustion gas mixing, the quality that its performance is good directly affects the performance of motor, current mixer functionalities relatively simple, usually the mixing of fuel and air is only accomplished, little to the flow-disturbing effect of gas, the effect of mixing is not very desirable.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of air and the uniform mixer of combustion gas mixing.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of mixer, comprise mixer case, mixing trunnion is set with in described mixer case, one end of described mixer case is provided with suction port, the other end is provided with air outlet, described mixing trunnion is positioned at one end of described mixer case air outlet, the mixing chamber of combination gas and air is provided with in described mixing trunnion, described mixer case is tightly connected with the described two ends mixing trunnion respectively, described mixer case mixes with described the combustion gas chamber forming annular between trunnion, described mixer case is provided with the gas joint being communicated with described combustion gas chamber, turbofan is provided with in described mixing trunnion, the described mixing chamber that described turbofan is positioned at, the flabellum of described turbofan is fixedly connected on the tube wall of described mixing trunnion, the tube wall of described mixing trunnion is provided with some exhausting holes, often arrange the axially-aligned of described through hole along described mixing trunnion, described tube wall between two described flabellums is at least provided with the described through hole of a row.
As a kind of preferred version, described mixer case is provided with balance tube, and described balance tube is positioned at described mixer case suction port one end.
As a kind of preferred version, described mixer case is provided with cushion rubber with described mixing between trunnion, is provided with cushion rubber between described mixer case and described gas joint.
Owing to have employed technique scheme, turbofan is provided with in the mixing chamber of mixing trunnion, flow-disturbing effect can be produced to gas, and the tube wall of mixing trunnion is provided with some exhausting holes, every exhausting hole is along the axially-aligned of described mixing trunnion, and combustion gas enters mixing chamber by through hole, makes mixing distance, thus air and combustion gas can be made to mix in mixing chamber, reach preferably mixed effect.
