The specific embodiment

Fig. 1 is a three-dimensional flow sake burner structure schematic diagram.This three-dimensional flow sake burner comprises shake device, a reverse inward turning cyclone impeller partially, and the vehement sieve ternary of a zero-clearance member is formed.Its burner body 1 is an endless tube shape, in the upper port of its external annulus, fix big reflector 4, propeller runner 3 is supported on big reflector 4 middle parts in reverse, middle reflector 7 is fixed on the tapered sleeve 8 of the internal ring wall that is stuck in main body 1, the vehement sieve 6 of the big zero-clearance of nest shape annular is stuck in the upper port of big reflector 4 and middle reflector 7, so the branch at reverse impeller 3 is cut off, it is main body mixing chamber 19 that main body 1 is divided into the bottom, the middle part is a secondary mixing chamber 18, be preheating regeneration room 17 between big vehement sieve 6 and the reverse interior propeller runner 3, central rings 2 is installed on the center of main body 1 by ventilation gland 9, vehement sieve 11 supports of the little zero-clearance of disc are on the horn mouth of central rings 2, outer propeller runner 10 is hung in the central authorities of the vehement sieve 11 of little zero-clearance, and little reflector 12 is attached on the horn mouth wall of central rings 2, shakes device 13 partially and is enclosed within on the gas nozzle circular shaft cylindrical.Above-mentioned inclined to one side shake device constitutes inclined to one side shake device by pinion 14 with the 13 coaxial gear that is connected 15 interlocks of the same sheet of shake partially, and its vibrating plate 13 stretches into the Taper Pipe porch of igniting in the adapter sleeve 16.Be used to cause combustion gas bias current injection and air-flow and shake, regulate the mixed proportion of air and combustion gas, and combustion gas is implemented fine setting at random, the high temperature adjusting of the completing combustion of assurance burner and smooth combustion and vehement sieve under composition and pressure oscillation situation.

Above-mentioned reverse inward turning cyclone impeller is one and has the entad circular plate type impeller of blade of torsional angle that blade evenly distributes along circumference; Be used for making the air-flow that moves at burner, by impeller the time, bump, splash, rebound, form vortex-like eddy flow, rush at vehement sieve, and, make burner combustion district uniformity of temperature profile airflow diversion and pressure leveling with certain angle of flare.

The vehement sieve of above-mentioned zero-clearance is laminated by double-deck thin slice sieve aperture zero-clearance dislocation and constitutes; Have two groups on the sake burner, one group is the vehement sieve 6 of the big zero-clearance of nest shape annular, places on 4 mouthfuls of the big reflectors, and another group is the vehement sieve 11 of the little zero-clearance of disc, places on 12 mouthfuls of the little reflectors; As burner nozzle, on this vehement sieve, form attached burning of thin layer, form self system's benign cycle, vehement sieve surface presents high temperature turns white-hot, and the state that reaches a high temperature at short notice has the effect of Fast Heating object, improves efficiency of combustion.

Is that example is illustrated that to the present invention the burning of three-dimensional flow sake burner is to enter burner body 1 injection Taper Pipe jointly by natural gas and absorption primary air with natural gas do combustion gas, air-flow is because of the shake device effect partially that entered the mouth, form bias current, enter main body mixing chamber 19, after mixed once, after throat's convergence diffusion, enter secondary mixing chamber 18, after secondary mixes, air-flow rushes at reverse inward turning cyclone impeller 3, again through splashing, bounce-back, drive in the wrong direction, after the operation such as pressure leveling, enter preheating regeneration room 17, after realizing mixing for the third time, sprawl to end sieve cambered surface fast, air-flow is influenced by end sieve structure, cause and the tangent and acceleration of end sieve multidimensional, enter top sieve, separate at the generation angle, cause multi-faceted diffusion, form the attached area scattering source of a large amount of fierce disturbances, air-flow ignites the back because of the effect of attached area scattering source, the combustion flame postposition, vehement sieve skin temperature raises, and meanwhile, has also improved the feedback preheat temperature to the mixed combustion air-flow, cause combustion velocity to be accelerated, vehement sieve surface temperature is further raise, thereby make burning enter an optimum thermodynamic cycle of self synergy, at this moment, vehement sieve presents high temperature very soon and turns white-hot, flame is limpid bright, the compass screen surface extreme temperatures, and be accompanied by the air-flow concussion sound that sends slight father-in-law father-in-law, auxiliary air is also by gas channel between the large and small fire dish simultaneously, enter vehement sieve surface, afterburning is provided, sake burning has at this moment entered the normal operation state.
