Description
technical field:
The present invention relates to float glass field, particularly a kind of float glass tin bath dusty gas discharge equipment.
background technology:
In sheet glass floating process, molten tin bath is molding device, and for the tin liquor of splendid attire fusing, the glass metal of fusing enters molten tin bath, and the sheet glass outlet molten tin bath of shaping, swims in glass metal and tin liquor is shakeout and forms sheet glass.Because tin liquor is oxidizable, the shielding gas that therefore must mix to nitrogen injection in molten tin bath with hydrogen, makes to remain malleation in molten tin bath, enters molten tin bath to stop air.Shielding gas injects from tin groove roof, oozes out from the blowout of molten tin bath import export and gap.Nitrogen stable chemical performance, in order to isolate tin liquor and air; Hydrogen can generate water vapor with remaining oxygen, for consuming oxygen further.
Molten tin bath by steel shell, inner lining refractory block material, tin liquor and other etc. form.In actual use, always have a small amount of oxygen and infiltrate in molten tin bath, tin liquor is oxidized, and at tin channel inlet place, high temperature is 1050 DEG C, easily produces tin protoxide (SnO) gas.Be down to after below 870 DEG C in temperature, tin protoxide gas can become the pressed powder of sn-containing compound, is called tin ash.If tin ash is shed on plate glass belt, light distortion point will be produced, form points of contamination.Thus, be necessary to remove dusty gas tin protoxide.
In Chinese patent " a kind of gas barrier of float glass tin bath " (200620123293.3), dusty gas is directly entered workshop, there is two problems, one is, contaminate environment; Two are, may cause hydrogen accumulation, detonation.In Chinese patent " the floatation glass production line melting furnaces molten tin bath with or without blocking atmosphere director " (201410030194.X), be provided with cleaning apparatus, dusty gas directly enters cleaning apparatus, still there is two problems, one is, because dusty gas temperature is still high, pollution substance tin protoxide gas can not become pressed powder completely, pollution substance can not be deposited completely, has part pollution substance still can be discharged into workshop, contaminate environment; Two are, may cause hydrogen accumulation, detonation.
The content of invention:
Object of the present invention is exactly to overcome the defect and a kind of float glass tin bath dusty gas discharge equipment provided that existing float glass tin dusty gas discharge equipment contaminate environment and hydrogen builds up.
the technical solution used in the present invention is as follows:
Be high-temperature gas mixture body from molten tin bath expellant gas, be made up of nitrogen, hydrogen and a small amount of tin protoxide gas, for removing tin protoxide composition wherein, mixed gas is cooled to less than 870 DEG C, make tin protoxide gas become tin ash powder, mixed gas becomes dusty gas, and in cleaning apparatus, dusty gas flow velocity is slack-off suddenly, the tin ash wherein mixed will be separated out and be deposited, then lights when being discharged by residual gas.
A kind of float glass tin bath dusty gas discharge equipment, it comprises at the bottom of molten tin bath, molten tin bath pond and molten tin bath sidewall, it is characterized in that molten tin bath sidewall is provided with perforate, perforate is connected with one end of cooling duct, the other end of cooling duct is connected with the side sidewall of cleaning apparatus, cooling duct, for reducing mixed gas temperature, the opposite side sidewall of cleaning apparatus is connected with discharge tube, and the bottom of cleaning apparatus is provided with dust stratification pipeline;
On the basis of such scheme, following further technical scheme can be had: it is characterized in that described discharge tube is provided with vent valves, for controlling gas emissions;
The end of described discharge tube is provided with portfire, and for preventing, hydrogen from building up, detonation;
The upper end of described dust stratification pipeline is provided with dust stratification ball valve, for building up tin ash; The lower end of dust stratification pipeline is provided with Unloading ball valve, for unloading tin ash.
The invention has the advantages that: solve the defect that existing float glass tin dusty gas discharge equipment contaminate environment and hydrogen are built up, improve glass quality percentage.Meanwhile, by making the tin protoxide Powder Recovery of float glass institute output, can reuse after reducing and smelting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
embodiment one:
As shown in Figure 1, a kind of float glass tin bath dusty gas discharge equipment, it comprises molten tin bath 1, at the bottom of molten tin bath pond 2 and molten tin bath sidewall 3, it is characterized in that molten tin bath sidewall 3 is provided with perforate 4, perforate 4 is connected with one end of cooling duct 6, the other end of cooling duct 6 is connected with the side sidewall of cleaning apparatus 7, the opposite side sidewall of cleaning apparatus 7 is connected with discharge tube 11, discharge tube 11 is provided with vent valves 12, the end of discharge tube 11 is provided with portfire 13, the bottom of cleaning apparatus 7 is provided with dust stratification pipeline 8, the upper end of dust stratification pipeline 8 is provided with dust stratification ball valve 9, the lower end of dust stratification pipeline 8 is provided with Unloading ball valve 10,
Described cleaning apparatus 7 is funnel shaped warehouses of likeness in form that very large and two ends, a space are provided with perforate.The dusty gas emitted from cooling duct 6 enters cleaning apparatus 7, because the space of cleaning apparatus 7 is very large, dusty gas flow velocity is slack-off suddenly, and powder contained in dusty gas will be separated out and is deposited on bottom, then slips into dust stratification pipeline 8 from the bottom of cleaning apparatus 7; The residual gas of discharging from cleaning apparatus 7 is lighted in the portfire 13 of discharge tube 11 end.
