Description
Technical field
The present invention relates to float glass process cover-plate glass and manufacture combustion gas heating installation 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 combustion-supporting combustion gas of combustion-supporting wind generates is heated melting furnaces by the cross flame of regenerator. In prior art, combustion-supporting wind mostly is the natural air adopting induced draft fan or gas blower directly to draw, and oxygen level only has 21% in air, combustion gas Thorough combustion is made just to need to introduce a large amount of air, freezing air preheating needs auxiliary preliminary heating device and thermal source, and freezing air directly inputs melting furnaces again reduces regenerator temperature and combustion heat utilization ratio. The oxygen level of lower concentration also is difficult to realize the Thorough combustion of combustion gas simultaneously, causes combustion gas to be wasted in a large number. Needing in float glass to use nitrogen and hydrogen as the shielding gas of molten tin bath, have the generation of a large amount of by-product oxygen in the process manufacturing nitrogen and hydrogen, oxygen is made emptying process by most producer.
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-supporting wind mixing equipment, need special oxygen to spray into rifle simultaneously, and need to be carried out by pool wall the special processings such as perforate, have impact on oxygen-enriched combusting and promote in float glass.
Summary of the invention
Complicated combustion gas, combustion-supporting wind mixing equipment is all needed for oxygen-enriched combusting mode in above-mentioned prior art, need special oxygen to spray into rifle simultaneously, and need to be carried out by pool wall the special processings such as perforate, have impact on the problem that oxygen-enriched combusting is promoted in cover-plate glass is produced, the present invention provides a kind of oxygen-enriched burning device.
For solving the problem, a kind of oxygen-enriched burning device provided by the invention is dealt with problems by following technical essential: a kind of oxygen-enriched burning device, comprise gas gun and wind conveying pipe, the inlet end of described gas gun is connected with Sweet natural gas adapter and the first oxygen mixer, described 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 compressed air gas source and oxygen source respectively;
The inlet end of described wind conveying pipe is connected with burner blower, the air suction inlet of burner blower is provided with the 2nd oxygen mixer, described 2nd oxygen mixer comprises oxygen jet and the drainage hood in bell mouth shape, the bigger diameter end of drainage hood is fixedly connected with the suction port of burner blower, the exit end of oxygen jet is positioned at the miner diameter end of drainage hood, and is also provided with multiple air intake hole on the sidewall of drainage hood.
Concrete, the first oxygen mixer arranged and the 2nd oxygen mixer realize mixing for twice of oxygen and combustion-supporting wind: in the 2nd oxygen mixer, high-concentration oxygen is sprayed by oxygen jet, Oxygen flow is when drainage hood, air enters into burner blower by air intake hole under the jet action of Oxygen flow and the absorption suction function of burner blower, the outlet of gas gun it is flow to again through wind conveying pipe, in above process, in drainage hood, oxygen forms diffusion flow, and air enters into Oxygen flow from multiple points of oxygen bundle, in addition the stirring of follow-up burner blower, make oxygen in the combustion-supporting wind of wind conveying pipe outlet side even, in the first oxygen mixer, the first oxygen mixer in three-port structure shape is the cavity structure being 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, in pressurized air and oxygen collision process due to violent stirring also makes oxygen and air can Homogeneous phase mixing, and the mixed gas of follow-up oxygen and air is when flowing to gas gun, mixed gas mixes with Sweet natural gas again, this is arranged so that the internal flame of gas gun exit end flame becomes short, simultaneously, make also can be formed oxygen-rich area in flame, namely the pyrolysis of Sweet natural gas is conducive to, it is beneficial to the rate of utilization of Sweet natural gas.
Further technical scheme is:
In order can try one's best after making oxygen enter drainage hood, the hydraucone sidewall near drainage hood flows, namely air and oxygen fully contacting in drainage hood it is convenient to, also comprise the diffusion vertebra head in different footpath, two ends, drainage hood internal fixtion is connected with vertebra head holder, described diffusion vertebra head is fixedly connected on vertebra head holder, and diffusion vertebra head is positioned at the central authorities of drainage hood.
