The utility model content
The technical problem that the utility model solves in, provide a kind of can using the furnace high-temperature off-gas recovery through after mixing as combustion air, realize the new equipment structure of circulating combustion.
The technological means that the utility model adopts is: a kind of blower fan eddy effusion combustion-aid structure, it comprises blower fan supervisor, whirlpool skirt, mixing chamber and mixing tube, and wherein, this blower fan is responsible for an end and is connected with combustion fan, the other end inserts in mixing chamber, connection whirlpool, mixing chamber side skirt; This mixing chamber comprises inlet end and ，Qi outlet side, outlet side is the conical pipe structure that area reduces, and this top, outlet side is connected with mixing tube.
This blower fan supervisor aims at the mixing chamber center line.
This blower fan supervisor stretches into the mixing chamber end, and the distance from top of its port of export and mixing chamber outlet side taper tubular construction is 10-50mm.
It is the conical pipe structure of reducing that this blower fan is responsible for its port of export.
This whirlpool skirt connects house steward, and this house steward is provided with some being in charge of of stove of stretching into.
This mixing chamber inlet end cross-sectional area is greater than blower fan supervisor and whirlpool skirt cross-sectional area sum.
This mixing chamber inlet end cross-sectional area is responsible for and the large 1-2 of whirlpool skirt cross-sectional area sum times than blower fan.
This blower fan supervisor caliber is 60-600mm.
The beneficial effects of the utility model are: the structure of blower fan supervisor and mixing chamber, can form eddy current near making the outlet of mixing chamber conical pipe, this eddy current drives and forms condition of negative pressure the gas in mixing chamber, strengthened the negative pressure effect, make hot flue gas in stove enter mixing chamber under the effect of pressure reduction, thereby mix with the combustion air at conical outlet place, heat exchange, improved the combustion air temperature, when reducing combustion air " oxygen " coefficient of excess, the heat that gas carries is recycled in burning.
The accompanying drawing explanation
Fig. 1 is structure principle chart of the present utility model.
The specific embodiment
As shown in Figure 1, blower fan eddy effusion combustion-aid structure of the present utility model, it comprises blower fan supervisor 1, whirlpool skirt 2, mixing chamber 3 and mixing tube 4, wherein, this blower fan supervisor 1 one ends are connected with combustion fan 6, and the other end inserts in mixing chamber 3, mixing chamber 3 connection whirlpool, side skirts 2; This mixing chamber 3 comprises the conical pipe structure that reduce for area inlet end 32 and 33，Qi outlet side 33, outlet side, and these 33 tops 31, outlet side are connected with mixing tube 4.
General, this whirlpool skirt 2 connects house stewards 5, this house steward 5 be provided with some stretch into stove be in charge of 51, draw hot flue gas in kiln.At the interior mixed gas of mixing chamber 3, through mixing tube 4, as the combustion air arm, use.
When the combustion air with certain kinetic energy blows out through combustion fan 6, while spraying with certain speed through blower fan supervisor, due to the combustion air ejected, to the γ-ray emission drainage in mixing chamber 3, and flue gas is taken away, mixing chamber 3 is interior can form condition of negative pressure, and inner flue gas of the stove is inhaled into by whirlpool skirt 2.An above-mentioned combustion air and inner flue gas of the stove mix in the position of mixing tube 4 front ends and carry out energy exchange, and the speed of a combustion air reduces, and by the speed of smoking gas, is increased, and enter mixing tube 4, the exit of last re-mixing tube 4, the two speed convergence balance, and can be used as the combustion air use.
In the present embodiment, this blower fan supervisor 1 aims at mixing chamber 3 center lines, it is the centre position that blower fan supervisor 1 is positioned at mixing chamber 3, this blower fan supervisor 1 stretches into mixing chamber 3 ends, this blower fan supervisor 1 its port of export 11 is similarly the conical pipe structure of reducing, and its port of export 11 is 10-50mm with top 31 distances of mixing chamber 3 outlet side 33 conical pipe structures.The conical pipe structure of blower fan supervisor and mixing chamber, can form eddy current near making the conical pipe outlet, this eddy current drives and forms condition of negative pressure the gas in mixing chamber, strengthened the negative pressure effect, make hot flue gas in stove enter mixing chamber under the effect of pressure reduction, and then with a combustion air at conical outlet place, mix, heat exchange, improved the combustion air temperature, when reducing combustion air " oxygen " coefficient of excess, the heat that gas carries is again utilized in circulating combustion.
For guaranteeing the mixing chamber negative pressure, these mixing chamber 3 inlet end 32 cross-sectional areas are greater than blower fan supervisor 1 and whirlpool skirt 2 cross-sectional area sums.But in order to guarantee to produce larger negative pressure, also unsuitable excessive, generally this mixing chamber inlet end cross-sectional area doubly is advisable with the whirlpool large 1-2 of skirt cross-sectional area sum than the blower fan supervisor.And this blower fan supervisor caliber is generally 60-600mm.
Be below one group of embodiment respectively manage data, wherein cast, caliber all can be according to required any settings.
Blower fan is responsible for the pipe that 1 internal diameter is 200mm, and length is with kiln length coupling.
The pipe that skirt 2 internal diameters in whirlpool are 200mm, be connected with another 200mm pipe.
The pipe that mixing tube 4 internal diameters are 250mm.
