Description
Technical field
The present invention relates to float glass technical field, particularly the melting end tank block protector in float glass smelting kiln.
Background technology
Flat Glass Furnace is the key equipment that sheet glass is produced, and melting end, cooling end, card neck, regenerator and other, consists of.Melting end by pool wall, breastwork, pond at the bottom of, top arch etc. forms.Pool wall is formed by refractory materials brick masonry, the thick 250mm of tank block, wide 400～450mm, height >=1250mm, and tank block is risen in metal level 30～50mm, does not carry kiln body weight; On tank block, place seam brick, can take off for melting furnaces hot repair, and leave dilatation joint; On dilatation joint, be tuckstone and breast wall brick.
In melting furnaces use procedure, glass metal can corrode melting end pool wall, on the position of the point of contact of metal level and pool wall, corrode the most serious, etch in mid-term vestige as shown in Figure 1 and later stage etch vestige, the easy attack sites of Here it is melting furnaces pool wall.For slowing down erosion, at this position corresponding arranged outside cooling duct, carry out specially air-cooled.Within a kiln cycle in age (7～12 years), although air-cooled pool wall can slow down erosive velocity, easily attack sites still can almost be etched completely, in the kiln later stage in age, can adopt the way of outer subsides refractory brick to continue to maintain reluctantly use, is the bottleneck that increases melting furnace life-span.
Zeng You overseas enterprise, is cooled with circulating water case and does the easy attack sites of melting furnaces pool wall, with recirculated water, does refrigerant.Because the boiling point of water only has 100 ℃, when water is cooked refrigerant, the position temperature that is cooled also just can not surpass 100 ℃, and 1480 ℃ of molten kiln temperatures, thereby must take away a large amount of heats, thus cause energy consumption to increase considerably.Therefore, although melting furnace life-span has increased, energy consumption increases considerably, and has to abandon the method.
Summary of the invention
Object of the present invention is exactly in order to overcome the easy attack sites refrigerating unit of existing melting furnaces pool wall, to have the defect that energy consumption is large, the easy attack sites refrigerating unit of a kind of Flat Glass Furnace pool wall providing.
To achieve these goals, the present invention has adopted following technical scheme:
The easy attack sites refrigerating unit of a kind of Flat Glass Furnace pool wall, comprise the pool wall of Flat Glass Furnace and the seam brick at top thereof, it is characterized in that: the easy attack sites between pool wall and seam brick, be provided with tin liquor and make the cooling back installation of medium, cooling back installation comprises and is connected in cooling tank between pool wall and seam brick, the top and the bottom of cooling tank one side are provided with respectively tin liquor outlet pipe and return line, the end of outlet pipe and return line connects spiral cooling tube, outlet pipe is provided with Jia Xikou, cooling duct is more separately set, spiral cooling tube is included in cooling duct again.
On the basis of technique scheme, can there is following further technical scheme:
Use heat-resisting steel material to make cooling back installation, and on outlet pipe, be provided with temperature sensor, in cooling tank, be provided with one group of dividing plate, cooling tank inner chamber enclosure is become to tin liquor serpentine pathway.In addition, in Jia Xikou position, be provided with shielding gas blowpipe 12, directly to adding Xi Kou, continue to brush shielding gas.
The present invention, in the easy attack sites of Flat Glass Furnace pool wall, arranges liquid natural circulating cooling device, by tin liquor, does refrigerant, then uses the outflow temperature of air-cooled control refrigerant.The characteristic of utilizing hot material to move upward, cooling tank dividing plate horizontal subdivision, forms the tin liquor flow passage that makes progress.With again
cooling ductby spiral cooling tube parcel, then cooling air is blown into, from cooling air outlet again, blows out from cooling air import again, with air quantity, controls spiral cooling tube temperature, also just controlled the temperature that tin liquor flows out, and also just controlled the temperature of the easy attack sites of pool wall.On cooling back installation top; setting adds Xi Kou; when initial, to cooling back installation, add solid tin grain; during operation as the Buffer Pool of tin liquor; oxidized for preventing from adding the high temperature tin liquor of Xi Kou; with shielding gas (nitrogen, hydrogen gas mixture) sealing, add Xi Kou, shielding gas be flat glass production line must use resource, without preparing separately.
In tin liquor spout temperature detection position, set up temperature sensor to control the high point of tin liquor temperature, low spot, when flowing out temperature over temperature control commanding elevation, tin liquor increases cooling air quantity, when flowing out temperature lower than temperature control low spot, tin liquor reduces cooling air quantity, when tin liquor flows out temperature, when temperature is controlled between spikes/low-points, keep cooling air quantity, make cooling box and glass metal contact site working temperature remain on temperature and control between spikes/low-points.
For increasing cooling performance, prevent tin liquor circulation dead angle, make also can enter circulation path near the tin liquor of melting furnaces inner side, with dividing plate, cooling tank enclosure is become to be easy to the serpentine pathway of tin liquor current global mechanism.
The invention has the advantages that: by tin liquor, do refrigerant, with high temperature steel, do parts, make cooling end megadyne temperature degree be controlled at 1000～1100 ℃, because cooling taken away heat will significantly reduce, increase the economic benefit that melting furnace life-span produces, the economic benefit of losing much larger than increase energy consumption.
