Description
[technical field]
The utility model relates to a kind of annealing kiln hot blast retracting device.
[background technology]
Glass producing process has many kinds, but basic process all is by the fusing kiln frit to be molten into liquid, enters annealing kiln again after moulding.Annealing kiln is provided with air inlet and exhaust outlet, lowers the temperature gradually by the air-cooled glass that makes, and eliminates stress, and becomes glass plate.Glass becomes the normal temperature product by the liquid of more than 1,000 degree, has a large amount of heat energy to be taken away by wind therebetween.The temperature of hot blast is generally about 300 degree, owing to do not recycle, this part heat is discharged in the air, thereby has wasted a large amount of heats.
[utility model content]
In view of this, be necessary the problem that is not used effectively at annealing kiln waste heat in the present process of glass to provide a kind of annealing kiln hot blast retracting device that can effectively utilize the annealing kiln waste heat.
A kind of annealing kiln hot blast retracting device comprises blast pipe, air collector, tube connector, air-heater, exhaust duct; Described blast pipe, air collector, tube connector, air-heater, exhaust duct connect in turn.The other end of described blast pipe connects annealing kiln, and the other end of described exhaust duct connects the fusing kiln.
Preferably, described blast pipe and tube connector are wrapped up by heat-preservation cotton.
Preferably, the thickness of described heat-preservation cotton is 100mm.
Preferably, the number of described blast pipe is three.
Preferably, the diameter of described three blast pipes is respectively 300mm, 500mm, 600mm.
Preferably, the diameter of described tube connector is 800mm.
Preferably, also comprise combustion fan, described combustion fan is connected with exhaust duct.
Preferably, also comprise exhaust-valve and hot-blast valve, described exhaust-valve and hot-blast valve all are arranged on the blast pipe.
Preferably, also comprise pressure maintaining valve, described pressure maintaining valve is arranged on the air collector.
Preferably, comprise also and replenish cold blast sliding valve and oxygen enrichment inlet valve that described additional cold blast sliding valve and oxygen enrichment inlet valve all are arranged on the tube connector.
The hot blast that annealing kiln is discharged is sent into the fusing kiln after annealing kiln hot blast retracting device is handled, the heavy oil combustion supporting wind-warm syndrome can be brought up to about 120 ℃ from original about 40 ℃, and the annealing kiln waste heat is fully used.
[description of drawings]
Fig. 1 is the schematic diagram of annealing kiln hot blast retracting device.
Fig. 2 is the schematic diagram of a kind of preferred implementation of annealing kiln hot blast retracting device.
[specific embodiment]
Fig. 1 is the schematic diagram of annealing kiln hot blast retracting device.Annealing kiln hot blast retracting device comprises blast pipe, air collector, tube connector, air-heater, exhaust duct.Blast pipe, air collector, tube connector, air-heater, exhaust duct connect in turn.The other end of blast pipe connects annealing kiln, and the other end of exhaust duct connects the fusing kiln.
The hot blast (being directly to drain in the air in the past) of more than 300 degree that annealing kiln is discharged causes in the air collector through blast pipe and mixes, and mixed hot blast is sent into air-heater through tube connector, and air-heater is sent hot blast into the fusing kiln.Hot blast mixes the hot blast of about 120 ℃ of back formation and makes heavy oil combustion supporting wind usefulness with the cold wind of melting furnaces bottom.The heavy oil combustion supporting wind-warm syndrome can be brought up to about 120 ℃ from original about 40 ℃ like this, the annealing kiln waste heat is fully used, thereby save heavy oil.
In the actual production, the hot blast temperature of annealing kiln zones of different is not necessarily identical, therefore, can all be installed into airduct in each zone, and heat is utilized more fully.
