Abstract
A kind of technology for drying wet-shaped refractory fibre products, including baking operation, it is characterised in that burnt using the air mix suspending state of coal dust particulate one during drying, steel substrate heat exchange, hothouse forced ventilation technique.Wet-shaped refractory fibre products are dried using present invention process, speed is fast, cycle is short, general product arid cycle is 2 ~ 4 days, thickness is 5 ~ 6 days arid cycle more than 100mm person.Low cost, energy utilization rate is high, and the energy is only the 50% of prior art drying process.
Description
Technical field
The invention belongs to drying means, it is related to technology for drying wet-shaped refractory fibre products.Suitable for carrying out thousand dry techniques to ceramic fibre wet moulding product.
Background technology
The technology for drying wet-shaped refractory fibre products of prior art, be to ceramic fiber cotton or leftover bits and pieces as base-material, adding water, the cotton pulp that bonding agent is made, using negative pressure filtering molding technique wet method manufacture product, by spontaneously dry, pit furnace dry（Such as flue-cured tobacco mode）Or steam drying.Due to the product made using this kind of production technology, water content is typically 1.4 1.8 times of fiber base material weight；And ceramic fibre is in itself excellent insulation material, moisture evaporation poor-performing when drying inside product, the thickness according to product is generally 48 days, and thickness is up to 10 days more than iOOrmn person's cycle.
The content of the invention
Therefore, there is many deficiencies in the drying process of prior art：For example, speed is slow, the cycle is long, and high cost, energy utilization rate is low；Dried product its moisture content about 1 1.5%, and moisture regain property is big, has a strong impact on the quality and heat-insulating property of product.
The purpose of the present invention, is the above-mentioned deficiency for overcoming prior art, there is provided a kind of speed is fast, cycle is short, low cost, energy utilization rate technology for drying wet-shaped refractory fibre products high.
Technology for drying wet-shaped refractory fibre products of the invention, including baking operation, it is characterised in that burnt using the air mix suspending state of coal dust particulate one when drying thousand, steel substrate heat exchange, hothouse forced ventilation technique.Described coal dust particulate refers to raw coal through being milled to 4>20〜8011
The coal dust particulate of m.Described suspended state burning, steel substrate heat exchange, refers to that coal dust particulate mixes into burner with appropriate air, and igniting makes its suspension combustion in the air, dry kiln steel substrate carry out heat exchange with hothouse.
Described hothouse forced ventilation technique, refers to that hothouse top sets air-introduced machine, makes to dry indoor air convection speed and is maintained at 0.2 0.
5m/s。
Specific embodiment
1. speed is fast, cycle is short, and general product arid cycle is 24 days, and thickness woke up the dry cycle of person thousand more than 100 for 56 days.
2. low cost, energy utilization rate is high, and the energy is only the 50% of prior art drying process.Below in conjunction with application example, the present invention is further elaborated：
Raw coal is first milled to 4 with raw coal grater>20〜80
U, be transported to coal dust particulate in coal-burning device by conveyer by the coal dust particulate of m；Adding the air mixing of proper proportion, igniting simultaneously makes its suspension combustion in the air.
Claims (4)
1. a kind of technology for drying wet-shaped refractory fibre products, including baking operation, it is characterised in that the Bian air mix suspending states of coal dust particulate one are burnt during drying, steel substrate heat exchange, hothouse forced ventilation technique.
2.-kind according to the technique described in claim 1, it is characterised in that described coal dust particulate, refers to coal dust particulate of the raw coal through being milled to.
3.-kind according to the technique described in claim 1, it is characterised in that described suspended state burning, steel substrate heat exchange, refers to that coal dust particulate mix into burner with appropriate air, and lighting a fire makes its suspension combustion in the air, heating steel substrate and hothouse
Carry out heat exchange.
4. a kind of technique according to described in claims 1, it is characterised in that described hothouse forced ventilation technique, refers to that hothouse top sets air-introduced machine, makes to dry indoor air convection speed and keeps.
