Each blender includes the housing that inside has cavity, and interior parallel two orifice plates that are provided with of housing, are evenly provided with respectively three above pores on each orifice plate; Described two orifice plates are divided into the first inlet plenum, the second inlet plenum and the mixed air vessel between two orifice plates by the cavity of housing; The gaseous mixture escape pipe that housing is provided with the first air inlet pipe being communicated with the first inlet plenum, the second air inlet pipe being communicated with the second inlet plenum outward and is communicated with mixed air vessel;
The gaseous mixture escape pipe of the first blender is connected with the first air inlet pipe of the 3rd blender, and the gaseous mixture escape pipe of the second blender is connected with the second air inlet pipe of the 3rd blender.
In the first air inlet pipe of described the first blender and the second blender, be respectively equipped with an air flow rate adjustment valve, in the second air inlet pipe of the first blender and the second blender, be respectively equipped with a natural gas flow adjustable valve.
All pores on described two orifice plates are all crisscross arranged.
Gaseous mixture escape pipe on described the 3rd blender is provided with Pressure gauge.
Adopt technique scheme, during work, electric control gear is controlled the open degree of natural gas flow adjustable valve and air flow rate adjustment valve, the air inlet ratio that makes natural gas and air is that the main component of 1:9.52(natural gas is methane, during combustion of natural gas, after a methane molecule and two oxygen molecule burnings, obtain a carbon dioxide molecule and two hydrones, the methane of unit volume needs the oxygen of two volumes just fully to burn, the aerial content of oxygen is 21%, therefore the methane of unit volume needs the air of 9.52 times just fully to burn.）。Air enters by the first air inlet pipe of the first blender and the second blender respectively, natural gas enters by the second air inlet pipe of the first blender and the second blender respectively, natural gas and air are carrying out after mixed once respectively in the mixed air vessel of the first blender and the second blender, mist enters into respectively the first air inlet pipe and second air inlet pipe of the 3rd blender again by gaseous mixture escape pipe separately, then enter into the first inlet plenum and second inlet plenum of the 3rd blender, by pore on orifice plate, enter in the mixed air vessel of the 3rd blender and carry out secondary mixing again, the mist mixing is finally discharged by the gaseous mixture escape pipe of the 3rd blender.All pores on two orifice plates are all crisscross arranged, and the resistance in the time of can reducing natural gas and air and enter mixed air vessel in mixed air vessel both sides by orifice plate, is conducive to natural gas and fully burns, and make air and natural gas obtain better, mix more equably.Pressure gauge plays the monitoring gaseous mixture escape pipe of the 3rd blender and the effect of mixed air vessel's pressure, thereby guarantees the safety work of whole mixing arrangement.
The utility model is reasonable in design, simple in structure, safe and reliable, after the constant ratio that regulates natural gas and air, make natural gas and air more even by twice mixing, not only saved fuel, and improved the efficiency of combustion of natural gas, practical, be easy to apply.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
