Abstract

The present invention discloses a high-efficiency and energy-saving three-dimensional gas flow combustor with a thin surface, which belongs to a gas combustion device. A polarization device of the combustor is arranged in the inlet position of an injection conical pipe through a connecting sheath, a reverse internal rotation impeller and an external rotation impeller are respectively arranged in an inner ring of a main body and a center ring of the main body, and gapless incandescent sieve is arranged on the upper end opening of the main body. Because of the action of the polarization device, the reverse internal rotation impeller and the gapless incandescent sieve, the mixed airflow of gas and air forming a three-dimensional airflow of a refracted flow, a rotational flow and a disturbed flow is rushed at the thin-sheet gapless incandescent sieve to form thin-surface combustion and boundary combustion. The surface layer of the incandescent sieve presents a high-temperature incandescent state, and a heated object has the advantages of quick temperature rise, high heat efficiency, gas saving, time saving and little pollution. Compared with similar combustors, the present invention can save 32 to 35% of gas, and the heat efficiency can reach 95%. The present invention is a novel product with the advantages of wide application, environmental protection and energy saving, and can be used for natural gas water heaters, coal gas water heaters, liquid gas water heaters and gas ranges.

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, in reflector 7 be stuck on the tapered sleeve 8 of internal ring wall of 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 of propeller runner 3 is cut off in reverse, 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, little sieve 11 supports 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 sheet 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 shake sheet 13 coaxial gear that is connected 15 interlocks partially, and it shakes sheet 13 partially and 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 propeller runner 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 the dislocation of double-deck thin slice sieve aperture zero-clearance 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, the angle takes place separate, 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, and vehement sieve surface temperature raises, meanwhile, feedback preheat temperature to the mixed combustion air-flow also is provided, has caused combustion velocity to be accelerated, vehement sieve surface 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, and flame is limpid bright, the compass screen surface extreme temperatures, and being accompanied by the air-flow concussion sound that sends slight father-in-law father-in-law, auxiliary air enters vehement sieve surface also by gas channel between the large and small fire dish simultaneously, afterburning is provided, and sake burning has at this moment entered the normal operation state.
