Description
Technical field
The utility model relates to float glass technolog field, specially a kind of online float glass process coated glass transition roller table
SO2 protects gas system.
Background technique
In the production process of float glass, from molten tin bath groove body aft end wall outer wall to one annealing kiln stem outer wall
Section thermal technology's facility is called transition roller table.Online float glass process plated film be common tin bath in floating glass production line and annealing kiln (or individually
Be arranged in molten tin bath or annealing kiln) in addition plating membrane reactor, it is straight on high temp glass surface by the online chemical vapour deposition technique of CVD
Connect the production process that plated film is carried out to float glass.
SO2 gas accesses a root hole pipe, enters transition roller table, hole by connecing the preformed hole above the transition roller table between roller
Face face roller tables upper glass plates face lower surface.SO2 gas can reduce tempering iridescence after contacting with glass-board surface, improve glass table
Surface intensity mitigates the scuffing of glass subsurface, has the effects of delaying to weathering of glass.But SO2 gas to molten tin bath, annealing kiln and
Plated film work in molten tin bath and annealing kiln has large effect, and permeating past SO2 will increase plate face infiltration tin rate, destroys tin
Slot atmosphere, damage Annealing Furnaces, the uniformity for destroying plated film film layer.But if not using SO2 gas, plate face tempering iridescence,
Phenomena such as scuffing of glass subsurface, weathering of glass, is again extremely serious.In practical applications, current way is in transition roller table
Front end access certain flow N2 sealing gland gas, carry out plate face sealing gland, prevent SO2 date back in molten tin bath pollute molten tin bath tin liquor, plate face,
Equipment.Tin sticky phenomenon is not solved at all under palette.Big SO2 flow often is opened to locate to mitigate tin sticky phenomenon in production simultaneously
Reason.SO2 meets the flow of production normal demand because aperture reason area coverage is limited, reaches needs of production and often opens
It is very big, reach production requirement by increasing flow, SO2, which does not have an effect part, when aperture is more just scatters and disappears in space；S02
Aerial root needs flow that can change according to actual production, and in normal common float glass, S02 flow is relatively large,
When plated film, because S02 has certain side effect to plated film film layer, the relatively normal float process of flow is on the low side, only its four/
One or so.When being measured using same flowmeter relatively during normal production because of range, flow is inaccurate when plated film, is difficult to control, S02 wave
Take it is also more, and when emergency episode processing need out big flow, to flow valve damage it is very big.It is outer that SO2 tank is located at slot bottom lower part
Side arrangement, operating point are located near jar, and operation needs personnel under control room to slot bottom every time, and observation and operation are less square
Just, waste time and and danger coefficient it is higher.S02 is toxic gas, larger to human injury, should reduce usage amount and people to the greatest extent
The time that member contacts.Air jet pipe is generally common stainless steel and is made, and has certain corrosivity, influences service life.SO2 from
It comes out that pressure is larger, and when decompression can rapidly absorb heat in tank, pipeline at pipe interface is caused to freeze.At this moment pipeline will be caused stifled
Plug, needs manually to close air inlet, could continue to supply to room temperature is restored after its deicing, influence the stability of production.It is existing simultaneously
The extra SO2 of technology passes through transition roller table gap penetration into workshop air, there is certain harm to human body.
Utility model content
In view of the above technical problems, the purpose of this utility model is to provide online float glass process coated glass transition roller table SO2
Gas system is protected, meets production requirement to greatest extent, greatly reduces the consumption of SO2 gas, facilitate operation, reduce personnel's
