Description
Technical field
The present invention relates to float glass process cover-plate glass and manufacture gas heating apparatus field, particularly relate to a kind of oxygen-enriched burning device.
Background technology
During float glass process cover-plate glass is produced, fire is changed in the timing that melting furnaces substantially all adopt, and the cross flame that the combustion-supporting combustion gas of combustion air generates by regenerator heats melting furnaces.In prior art, combustion air mostly is the natural air that adopts air-introduced machine or air blast directly to draw, and oxygen content only has 21% in air, combustion gas is fully burnt and just need to introduce a large amount of air, cold air preheating need to be assisted pre-heating device and thermal source, and cold air is directly inputted melting furnaces and reduced regenerator temperature and combustion heat utilization rate.The oxygen content of low concentration is also difficult to realize the abundant burning of combustion gas simultaneously, causes combustion gas to be wasted in a large number.In float glass, need to use nitrogen and hydrogen as the protective gas of molten tin bath, have the generation of a large amount of by-product oxygen in the process of manufacturing nitrogen and hydrogen, most producers make emptying process by oxygen.
In prior art cover plate process of glass, also there is employing oxygen-enriched combustion technology, and existing multiple oxygen-enriched combusting mode all needs complicated combustion gas, combustion air mixing apparatus, need special-purpose oxygen to spray into rifle simultaneously, and need to pool wall, carry out the specially treateds such as perforate, affect oxygen-enriched combusting and promoted in float glass.
Summary of the invention
For oxygen-enriched combusting mode in above-mentioned prior art, all need complicated combustion gas, combustion air mixing apparatus, need special-purpose oxygen to spray into rifle simultaneously, and need to carry out to pool wall the specially treateds such as perforate, affect the problem that oxygen-enriched combusting is promoted in cover-plate glass is produced, the invention provides a kind of oxygen-enriched burning device.
For addressing the above problem, a kind of oxygen-enriched burning device provided by the invention solves problem by following technical essential: a kind of oxygen-enriched burning device, comprise gas gun and wind conveying pipe, the arrival end of described gas gun is connected with natural gas and takes over and the first oxygen mixer, described the first oxygen mixer is three-port structure shape, an opening of the first oxygen mixer is connected with gas gun, and two other opening of the first oxygen mixer connects respectively compressed air gas source and oxygen source;
The arrival end of described wind conveying pipe is connected with combustion fan, the air suction inlet of combustion fan is provided with the second oxygen mixer, described the second oxygen mixer comprises oxygen jet and is the drainage hood of bell mouth shape, the bigger diameter end of drainage hood is fixedly connected with the suction inlet of combustion fan, the port of export of oxygen jet is positioned at the miner diameter end of drainage hood, and is also provided with a plurality of air suction inlets on the sidewall of drainage hood.
Concrete, the first oxygen mixer arranging and the second oxygen mixer realize mixing for twice of oxygen and combustion air: in the second oxygen mixer, high-concentration oxygen is sprayed by oxygen jet, Oxygen Flow is when drainage hood, air enters into combustion fan by air suction inlet under the jet action of Oxygen Flow and the absorption suction function of combustion fan, through wind conveying pipe, flow to again the outlet of gas gun, in above process, in drainage hood, oxygen forms diffuse flow, and air enters into Oxygen Flow from a plurality of points of oxygen beam, in addition the stirring of follow-up combustion fan, make in wind conveying pipe outlet side combustion air oxygen even, in the first oxygen mixer, the first oxygen mixer that is three-port structure shape is the cavity structure that is provided with three openings, preferred compressed air gas source interface and oxygen source interface angular range at 25 ° within the scope of 40 °, like this, compressed air with in oxygen collision process, because violent stirring also makes oxygen, can evenly mix with air, and the mist of follow-up oxygen and air is while flowing to gas gun, mist mixes with natural gas again, this internal flame that is arranged so that gas gun port of export flame shortens, simultaneously, make also can form oxygen-rich area in flame, be conducive to the pyrolysis of natural gas, be beneficial to the utilization rate of natural gas.
Further technical scheme is:
For oxygen being entered can try one's best after drainage hood, near the horn mouth sidewall of drainage hood, flow, be convenient to air with oxygen fully contacting in drainage hood, the diffusion vertebra head that also comprises two ends reducing, in drainage hood, be fixedly connected with vertebra head frame, described diffusion vertebra head is fixedly connected on vertebra head frame, and diffusion vertebra head is positioned at the central authorities of drainage hood.
