Description
Technical field
The utility model relates to a kind of drying system, especially a kind of ammonium sulfate drying system.
Background technology
At present, the ammonium sulfate drying usually adopted has three kinds of rotary drying, pneumatic conveying drying and vibra fluidized bed dryings.
(1) advantage of rotary drying is that production capacity is strong, allowable fluctuation range is larger, easy to operate, and the installed power of whole system is less.Shortcoming is that investment is large, and floor space is large; Ammonium sulfate is serious at the sticky wall of the leading portion of drying machine, and the poor continuity of system operation needs the time cut-out cleaning to safeguard, or in cylinder, increases cleaning plant, has increased equipment investment.
(2) advantage of pneumatic conveying drying is that dry tenacity is large, the time is short, the thermal efficiency is high, treating capacity is large, occupation area of equipment is little.Shortcoming is that air velocity is higher, and product pellet is had to certain wearing and tearing and pulverizing; Because the operate power that makes greatly blower fan with air quantity increases, operating cost is higher; Material is easy to sticky wall, even also there will be sticky wall problem at the leading portion of pneumatic drier.
(3) though that the advantage of vibrated bed drying is equipment investment is higher than pneumatic conveying drying, more much lower than rotary drying, it is medium that floor space also belongs to, but the installed power of whole system is little, and operating cost is low; The continuity of system operation is better; Residence time of material is short, rate of drying is large, maintenance of equipment is convenient, and the residence time of material capable of regulating, can partly solve the sticky wall problem of viscous material.Shortcoming is that the material that particle is large easily forms channel and viscous motion district, when particle size distribution is wide, carries under one's arms serious, also exists air distribution plate to leak the problem of material.

The utility model is main drying with the internal heat type fluid bed dryer.The drying of ammonium sulfate and coolingly complete in an equipment, ammonium sulfate drying/cooling required heat/cold is provided jointly by the built-in pipe heat exchanger of equipment and hot cold air, has that system thermal efficiency is high, good stability, product moisture content is low and stay-in-grade characteristics.The internal heat type fluid bed dryer is a kind of novel dried technology grown up on conventional fluidized bed drying and indirect heating type dry-basis.It is immersed in tubing heat exchanger in the fluidized drying material, a kind of energy-efficient drier that material dewatering institute calorific requirement is provided with hot-air by pipe laying heat exchanger and fluidisation respectively.The air dielectric that enters fluid bed mainly works the wet effect of taking.
Wet ammonium sulfate material is delivered to premixed device from the centrifuge centrifugal dehydration through conveying equipment, and the dry ammonium sulfate of simultaneity factor is promoted to premixed device by the returning charge discharging opening of drying machine by elevator; In premixed device, dry wet stock fully stirs, and makes material loosening and delivers into drying machine.In fluid bed, wet stock contacts above air distribution plate with hot-air, and material particles is suspended among air-flow, forms fluidization; Pipe heat exchanger is immersed in fluidised material, in heat exchanger tube, is connected with steam, provides most material dewaterings required heat by heat exchanger.Dried finished product is cooling with the pipe heat exchanger that is connected with cooling water by cooling-air at the colling end of drying machine.Final products are discharged from discharging opening, and dusty gas enters atmosphere through dust arrester installation-cyclone separator and wet scrubber-purification by air-introduced machine.Qualified product overfall by drying machine after cooling is discharged, and discharges through the finished product bleeder valve.
The beneficial effects of the utility model are, the system continuously-running, and the thermal efficiency is high, stable, easy to operate, can realize automatic control, is applicable to fairly large production, and floor space reduces, and invests lowly, and operation and maintenance cost is low.
Adopted back-mixing mechanism, successful solution centrifuge discharging fluctuation problem, greatly reduced impact drying system caused because of centrifuge discharging moisture content fluctuation; Greatly reduce simultaneously the moisture content that the ammonium sulfate material enters drying machine, material is looser, makes the continuity of operation of system be better than other system.
Main drying machine feeding zone does not arrange buried tube heat exchanger, the Wei Liaochuan district, and thickness of feed layer is 3 times of common fluid bed, in the fluid bed dilution zone, realizes the material blending again to falling into, and further reduces the moisture content of material, material is looser.Adopted advanced side air-out layering type air distribution plate, this structure fabric wind evenly, does not leak material, and mechanical strength is good, and the life-span is long.Not only the fluidized state of material can be improved, and the material air compartment that bleeds can be effectively prevented; Its side direction motive force makes material (containing bulk materials) shift to continuously and stably discharging opening, has avoided, because bulk materials concentrates on " the mounting the throne " of causing on air distribution plate, having improved the continuity of operation of system.
Aspect the dry production of ammonium sulfate, the utlity model has desirable effect.
