Description
Technical field
The utility model relates to the technical field of material of construction production industry and energy-conserving and environment-protective, especially a kind of energy saving and environment friendly perlite production unit.
Background technology
Perlite is a kind of inorganic heat preserving and heat insulation material, has been widely used in metallurgy, building material industry, and producing perlitic equipment, to develop into coal gas and electricity by coal firing rotary drying kiln, coal firing puffing furnace be the rotary drying kiln and the expanded electric furnace of thermal source.The classification recovery technology is being applied.But heat recovery still is in the development phase, and the great amount of high-temperature flue gas directly enters atmosphere and causes energy dissipation and environmental pollution.
The utility model content
The purpose of the utility model is that existing power consumption is high in producing to present domestic perlite; Environmental pollution is serious; The problem that output is not high; More energy-conservation a kind of perlite production unit free from environmental pollution again is provided, and it mainly is made up of raw material hole, lift, rotary drying kiln, puffing furnace, fly-ash separator, induced draft fan, volume damper, settling pocket, finished bin, whirlwind collector, gas blower and UNICOM's airduct; The lift lower end in raw material hole, the upper end rotary drying stove that links to each other, the discharge port of rotary drying stove links to each other with the opening for feed of puffing furnace; Rotary drying stove and be connected by pipe with fly-ash separator, fly-ash separator links to each other with induced draft fan through airduct, is communicated with puffing furnace through volume damper; Puffing furnace is communicated with settling pocket; Settling pocket is communicated with the whirlwind collector, and the whirlwind collector is communicated with finished bin by airduct on one side, and the other side is communicated with gas blower; The whirlwind collector also is communicated with into rotary drying kiln through airduct, and whole system is the closed-loop control state.The heating of being adopted fast, clean environment firendly, energy-conservation and be easy to realize temperature automatically controlled Frequency Induction Heating puffing furnace, can reduce the energy consumption of pearl stone puffing; The high-temperature flue gas that whirlwind collector pipe core is discharged is introduced rotary drying kiln by pipeline raw material is dried, and this high-temperature flue-gas has so just reduced the energy consumption of raw material stoving greater than 600 degrees centigrade; The underbalance pulse sack cleaner of said employing reclaims the powdery perlite, after purifying, also has the outlet entering puffing furnace of the flue gas of certain temperature from induced draft fan, and fume afterheat is further utilized.The rotary drying stove is installed in elevated platform, and its discharge port directly links to each other with the puffing furnace opening for feed.
Adopt the beneficial effect of the utility model perlite production unit to be: owing to adopted the Frequency Induction Heating puffing furnace, quick heating is prone to temperature control, the body of heater loss on ignition is little, has prolonged its work-ing life, thereby has improved expanded efficient; Through shortening supplied flue gases pipeline, and the recycle fume afterheat, energy consumption is reduced greatly; This plant factor improves, and the maintenance amount reduces; This system controls automatically, saves manpower, and improves operating environment, reduces greenhouse gas emission, has remarkable economic efficiency and social benefit.

Embodiment
Below in conjunction with accompanying drawing the utility model is specified: as shown in the figure; A kind of perlite production unit mainly is made up of raw material hole 1, lift 2, rotary drying kiln 3, puffing furnace 4, fly-ash separator 5, induced draft fan 6, volume damper 7, settling pocket 8, finished bin 9, whirlwind collector 10, gas blower 11 and UNICOM's airduct; Lift 2 lower ends in raw material hole 1, the upper end rotary drying stove 3 that links to each other, the discharge port of rotary drying stove 3 links to each other with the opening for feed of puffing furnace 4; Rotary drying stove 3 and be connected by pipe with fly-ash separator 5, fly-ash separator 5 links to each other with induced draft fan 6 through airduct, is communicated with puffing furnaces 4 through volume damper 7; Puffing furnace 4 is communicated with settling pocket 8; Settling pocket 8 is communicated with whirlwind collector 10, and whirlwind collector 10 is communicated with finished bin 9 by airduct on one side, and the other side is communicated with gas blower 11; The whirlwind collector also is communicated with into rotary drying kiln 3 through airduct, and whole system is the closed-loop control state.
By raw material lift 2 raw material is promoted entering rotary drying kiln 3 from raw material hole 1 and carry out raw material stoving,, directly get into puffing furnace 4, carry out expanded through the high-temperature material of rotary drying kiln preheating.Fine perlite is collected through settling pocket 8, whirlwind collector 10, by gas blower 11 the finished product perlite is sent into finished bin.Discharge the high temperature cigarette from whirlwind collector pipe core and get into the thermal source of rotary drying kiln as rotary drying kiln drying material through smoke pipe.Carry out heat exchange from rotary drying kiln.What also contain the discharge of perlitic flue gas of powdery and finished bin after the cooling contains the perlitic flue gas of powdery under the suction of induced draft fan 6, gets into pulse bag type dust collector and reclaims the powdery perlite.Induced draft fan is discharged the warm air with certain temperature and is got into puffing furnace through regulating valve, and whole production system has realized closed-loop control.The waste heat of puffing furnace has obtained abundant application, and environment improves, small investment of production equipment, and floor space is little, economic benefit, obvious environment benefit.
