Description
Technical field
The utility model belongs to the fibre technical field of drying, is specifically related to a kind of energy-saving fibre dry kiln.
Background technology
The refractory fibre product of wet production contains a large amount of moisture and organic and inorganic bonding agent, need be through heat drying, curing and typing.What fibre dry kiln in the market adopted is electrical heating directly-heated type dry kiln or hot air type dry kiln.
Electrical heating directly-heated type dry kiln be with heating be arranged in the two sides of dry kiln inside/or three face walls on, by heat radiation heating and dried fibres goods that heating energising back heating is produced, the wet-emitting blower that the damp-heat that the dry run water evaporates produces is installed by dry kiln directly is discharged in the atmosphere.
The hot air type dry kiln is the hot blast that electricity consumption heating hot blast protects or fuel gas hot-blast stove produces, and introduces heat drying fibre in the dry kiln by blower fan, and the wet-emitting blower that the damp-heat that the dry run water evaporates produces is installed by dry kiln directly is discharged in the atmosphere.
Adopt electrical heating directly-heated type dry kiln and hot air type dry kiln dried fibres goods, have following shortcoming:
1, electrical heating directly-heated type dry kiln is the heat radiation heat drying fibre that relies on heating energising back heating to be produced.
1) wet-emitting blower installed by dry kiln by damp-heat that water evaporates produced of fibre dry run directly is discharged in the atmosphere, has also taken away heats a large amount of in the stove when damp-heat is directly drained, causes a large amount of heat-energy losses.
2) non-uniform temperature in the dry kiln, too high and produce yellowing phenomenon from the near product surface temperature of heating.
2, the hot air type dry kiln is that dependence electrical heating hot-blast stove or fuel gas hot-blast stove are hot air source, and the hot blast that is produced is introduced dry kiln heat drying fibre by blower fan.
1) wet-emitting blower installed by dry kiln by damp-heat that water evaporates produced of fibre dry run directly is discharged in the atmosphere, has also taken away heats a large amount of in the stove when damp-heat is directly drained, causes a large amount of heat-energy losses.
2) turnover wind all adopts the single tube mode to concentrate air intake and air draft, and air intake and air-out point are too concentrated, cause the kiln temperature inequality.
Because the refractory fibre product of wet production contains a large amount of moisture, the dry cycle is generally all long, between the fibre dry period, wet-emitting blower otherwise the running that stops comes hydrofuge gas, simultaneously, cause a large amount of heat-energy losses, make production cost increase also at the heat in the stove taken away that does not stop.
Summary of the invention
The purpose of this utility model provides a kind of energy-saving fibre dry kiln, makes its defective that can overcome the existing in prior technology energy waste, and it is low to reach dried fibres goods energy consumption, purpose of energy saving.
The technical scheme that its invention task of finishing the utility model is adopted is:
A kind of energy-saving fibre dry kiln, a side wall and bottom at dry kiln kiln body all have usefulness so that hot blast enters the air chamber in the kiln, it is kiln headwall inlet plenum and kiln bottom air chamber, and be interconnected between two air chambers, in order to guaranteeing that hot blast enters ring week and the bottom in the dry kiln, thereby the relative fibre of hot blast that enters in the dry kiln is evenly distributed; All set adjustable pitch width narrow or big or small ventilative slit or air-vent in each air chamber fibre direction in kiln, further guarantee being heated evenly of the interior fibre of dry kiln; At dry kiln kiln body another kiln end relative, have and use so that the air chamber that hot blast expels from kiln, i.e. kiln headwall exhaust chamber with kiln headwall inlet plenum; In kiln, all set adjustable pitch width narrow or big or small ventilative slit or air-vent, further guarantee being heated evenly of the interior fibre of dry kiln to kiln headwall exhaust chamber direction; Described kiln body is provided with the hydrofuge exhaust duct, the hydrofuge exhaust duct other end that is communicated with dry kiln is communicated with the heat exchanger of UTILIZATION OF VESIDUAL HEAT IN by the frequency conversion wet-emitting blower, described heat exchanger is communicated with the cold wind blast pipe, and the damp-heat air outlet of described heat exchanger is communicated with chimney by blast pipe; The pre-hot blast outlet of described heat exchanger is communicated with the kiln headwall inlet plenum of dry kiln by pre-hot blast discharge pipe, thermal circulation fan, electrical heating hot-blast stove; The kiln headwall exhaust chamber of dry kiln is communicated with the electrical heating hot-blast stove by discharge pipe, thermal circulation fan, circulation airduct.Make the air that has uniform temperature of discharging in the dry kiln be introduced into heat exchanger, and with the cold air heat exchange that enters heat exchanger after by blast pipe to smoke stack emission, reduce the damp-heat air temperature of discharging from dry kiln; Through the air that has uniform temperature after the preheating then by pre-hot blast discharge pipe mix with the warm wind of discharging afterwards by discharge pipe in the kiln enter the electrical heating wind furnace and heat once more by thermal circulation fan after, enter in the dry kiln, improve the temperature that enters the hot-blast stove cold air, reach energy saving purposes.
A kind of energy-saving fibre dry kiln that the utility model proposes has overcome energy waste, uneven temperature defective that the dry refractory fibre product of existing dry kiln exists, and it is low to have reached dry kiln fibre energy consumption for drying, purpose of energy saving.
