Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, a kind of float glass system, including molten tin bath 10 on 10 side wall of molten tin bath, is higher than tin
Feed inlet 11 is set at liquid liquid level, and air inlet 12, the air inlet 12 is arranged in 11 top of feed inlet at feed inlet 11
External heatable wind cabin 16.Wind cabin 16 is provided with protective gas, and generally inert gas such as nitrogen etc. is mixed with a small amount of hydrogen
It constitutes.After protective gas is heated to required temperature, high temperature protection gas enters from air inlet 12 in molten tin bath 10, in protection
Meanwhile on the one hand higher temperature can be kept with auxiliary glass liquid, it scatters in tin liquor so as to more uniform；On the other hand, lead to
Adjustment air inlet direction and size are crossed, glass metal can also be helped faster more uniformly orderly to scatter in tin liquor；In addition, protection gas
During crossing molten tin bath 10, temperature gradually decreases body, can assist the glass metal fast cooling shaping of 10 back segment of molten tin bath.
Certainly, it is booster action that protective gas, which adjusts the temperature of glass metal, and molten tin bath 10 further includes being heated to tin liquor in itself
Device, this part heating device are the prior art, can according to need and carry out subregion, controllable heating to tin liquor.
Discharge port 16 is provided on the 10 opposite side side wall of molten tin bath, 10 top of molten tin bath, close 17 end of discharge port are also set
It is equipped with switchable air outlet 13.More optimal solution are as follows: the air outlet 13 passes through pipeline and the external gas sampling of aspiration pump 14
Device.Protective gas after a period of time, can mix some polluted gas such as vapor, tin steam, in molten tin bath 10 in molten tin bath 10
The lower position of back segment, temperature is easy drippage pollution glass metal, makes glass metal surface irregularity, reduce glass plate preparation at
Power.After air outlet 13 and aspiration pump 14 are set, can temperature is lower, contaminated protective gas has constantly extracted molten tin bath out
10, it on the one hand avoids pollution gas and stays in inside molten tin bath 10, fall after cooling on glass metal (plate) surface.
Better scheme are as follows: around the air outlet 13 and discharge port 17 is between 10 top of molten tin bath, is additionally provided with high temperature resistant
Water absorber 15.Around the air outlet 13, range is specifically limited as range present in the cooling temperature of vapor, generally
For, refer within the scope of 13 surrounding 5cm of air outlet.Because of the presence of aspiration pump 14, gas tends to lean on to 13 position of air outlet
Closely, in fact it could happen that part, which also has not enough time to leave molten tin bath 10 but has been cooled to the vapor of liquid, is deposited in air outlet 13 weeks
It encloses, or even is flowed down along the side wall of the molten tin bath 10 close to air outlet 13.It, can be by this part water after high temperature resistant water absorber 15 is set
Vapor sorption avoids its drippage to inside.Better scheme are as follows: detachably connect between the high temperature resistant water absorber 15 and molten tin bath 10
It connects, absorbs water when high temperature resistant water absorber 15 close to when being saturated, it can be replaced, it is of course also possible to directly regularly replace.
The high temperature resistant water absorber 15 needs to be resistant to 300 DEG C or more of temperature.For example use ceramics/gold resistant to high temperature
The production of the materials such as category becomes cage structure (width of mesh of the structure, which is subject to, does not leak out internal material), inside filling high temperature resistant
Water-absorbent material, such as high temperature resistant water-absorbing resin (entitled " the fire resistant polypropylene acid absorption resin of sodium that such as China University Of Petroleum Beijing delivers
Preparation and performance " in water-absorbing resin), bentonite resistant to high temperature (if selecting bentonite, needs more timely for another example
High temperature resistant water absorber 15 is replaced, when temperature being avoided to be increased to 300 DEG C or more, the moisture of absorption is lost, to lose water suction
Effect).
The float glass system further includes glass metal process units and glass annealing device.
More optimal solution are as follows: the glass metal process units is the glass melting furnace 20 of submerged combustion heating, and the glass is molten
Inside cellar 20, top one inlet duct at least be set, the inlet duct including at least a pair extend to 20 bottom of glass melting furnace,
And the gas inlet pipe 21 that does not contact with bottom and gas inlet pipe 23 being helped, the other end of each air inlet pipe is connect with gas storehouse, described
It gas inlet pipe 21 and helps on gas inlet pipe 23 several openings is respectively set, each opening, which respectively corresponds, to be arranged in pairs
Several gas outlet ends 22 and combustion-supporting gas outlet side 24；Position is additionally provided on the glass melting furnace 20 higher than locating for each inlet end
The feed inlet 29 of extreme higher position.The glass melting furnace 20 further includes preheating device, can be to set in 20 interior of glass melting furnace
Heating wire etc. is set, 20 internal temperature of glass melting furnace to be preheating to the burning point higher than combustion gas in advance.
The combustion gas that is arranged in pairs and gas inlet device is helped, fixed point, quantitative burning not only may be implemented, but also can be right
Glass metal has certain mixing function.On the one hand the imperfect combustion for avoiding combustion gas generates contaminants glass metal, a side
Face also avoids Some gases from also having not enough time to and help contacts fuel gas to escape glass metal, causes waste of material.
More optimal solution are as follows: be provided with exhaust gas air-out apparatus 27 at the top of the glass melting furnace 20；The exhaust gas air-out apparatus
It is connect at 27 fever with the hot end of temperature-difference power generation module 28, the feeder ear of the temperature-difference power generation module 28 and the wind cabin 16 connect
It connects.The heat generated when manufacturing glass metal is used to generate electricity, the protective gas in wind cabin 16 is heated again, will not only generated
A large amount of Waste Heat Reuses get up to heat protective gas heat, realize and utilize again；And the protective gas of heat can also
Glass metal is heated with auxiliary, part heating tin liquor has been saved, has maintained the energy required for required temperature in molten tin bath 10,
Energy conservation and environmental protection.Meanwhile will be reused after waste-heat power generation, it also avoids directly carrying out heat exchange with protective gas with exhaust gas, to protection
Gas causes unnecessary pollution.
