Abstract
The utility model discloses a modular spray fluidized drying machine, including spray drying tower, fluidized drying machine, cyclone, sack cleaner and draught fan, the spray drying tower still including set up the discharge gate of bottom with set up play tuber pipe laterally, be provided with air inlet, feed inlet, discharge gate and gas vent on the fluidized drying machine, go out the air inlet that the tuber pipe passes through pipe connection fluidized drying machine, the discharge gate is connected to the feed inlet of fluidized drying machine through the feeder, the air exit of fluidized drying machine connects gradually cyclone, sack cleaner and draught fan, cyclone, sack cleaner bottom all are equipped with the discharge gate. The utility model discloses in, spray drying tower and fluidized drying machine use together, to the high material of aridity requirement, carry out preliminary drying in the spray drying tower, and the aridity of material reaches 0.5 -0.7, then carries out further drying in the fluidized drying machine, makes the aridity fall to below 0.3, can reduce energy consumption, energy saving by a wide margin.
Description
Technical field
The utility model relates to a kind of combined type spray fluidized dryer, belongs to drying equipment technical field.
Background technology
Spray dryer is the one of continous way atmospheric dryer, adopt atomizer that material liquid is separated into droplet, and obtain product with the dry droplet of hot gas, main working process is: extraneous fresh air is by air cleaner, air blast, enter air heater, make air themperature bring up to about 160 DEG C, send drying tower to.Before entering drying tower, hot-air first by air uniform plate, makes hot-air be uniformly distributed, prevents vortex, avoid coke powder to occur, to ensure drying effect.Need the material liquid of dry process, atomizer is delivered to by compression pump, feed liquid is with vaporific ejection and mix with hot-air, material Micro-picking heat, moment moisture evaporation, forms powder falls downward, through one section of constant rate of drying, further transpiring moisture, coarse granule falls into the conical lower portion of drying tower and discharges.Dried material fine silt is separated through cyclone separator with the mixture of Low Temperature Wet air, and off-air is discharged by exhaust blower, and dry fine powder product falls is discharged continuously by discharger.
Material at 1-3 is required for aridity, the off-air temperature of spray dryer after being separated is at about 50 DEG C, the heat contained is not high, if dry materials degree requires below 0.3, direct employing spray dryer reaches predetermined aridity, then need the hot-air of more than 250 DEG C to carry out drying, and can reach about 100 DEG C from the mist temperature that drying tower is discharged, energy consumption is high.
Utility model content
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of combined type spray fluidized dryer reducing energy consumption, improve dry materials degree.
The technical solution adopted in the utility model is: a kind of combined type spray fluidized dryer, comprises spray drying tower, fluidized dryer, cyclone separator, sack cleaner and air-introduced machine;
Described spraying dry top of tower is provided with atomizer, and atomizer is connected with hopper, and described spraying dry top of tower is also provided with blast pipe;
Described spray drying tower also comprises the discharging opening being arranged on bottom and the discharge pipe being arranged on side, described fluidized dryer is provided with air intake, charging aperture, discharging opening and exhaust outlet, described discharge pipe connects the air intake of fluidized dryer by pipeline, described discharging opening is connected to the charging aperture of fluidized dryer by feed appliance, the exhaust outlet of fluidized dryer connects cyclone separator, sack cleaner and air-introduced machine successively, is equipped with discharging opening bottom cyclone separator, sack cleaner.
In the utility model, spray drying tower and fluidized dryer are used in conjunction, require for high material for aridity, preliminarily dried is carried out in spray drying tower, the aridity of material reaches 0.5-0.7, then in fluidized dryer, carry out further drying, make aridity drop to less than 0.3, can significantly reduce energy consumption, economize energy.
Accompanying drawing explanation
Fig. 1 is the structural representation of combined type spray fluidized dryer of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further described.
Detailed description of the invention
Embodiment 1
As shown in Figure 1, this combined type spray fluidized dryer, comprises spray drying tower 1, fluidized dryer 2, cyclone separator 3, sack cleaner 4 and air-introduced machine 5;
Described spraying dry top of tower is provided with atomizer 6, and atomizer 6 is connected with hopper, and described spraying dry top of tower is also provided with blast pipe 11;
Described spray drying tower also comprises the discharging opening 12 being arranged on bottom and the discharge pipe 13 being arranged on side, described fluidized dryer is provided with air intake 21, charging aperture 22, discharging opening 23 and exhaust outlet 24, described discharge pipe 12 connects the air intake 21 of fluidized dryer 2 by pipeline, the discharging opening 12 of described spray drying tower 1 is connected to the charging aperture 22 of fluidized dryer 2 by feed appliance, the exhaust outlet 24 of fluidized dryer connects cyclone separator 3, sack cleaner 4 and air-introduced machine 5 successively, is equipped with discharging opening bottom cyclone separator 3, sack cleaner 4.
During work, liquefied mass is sent in atomizer and is sprayed by feeding engine from hopper, the hot-air of 220 DEG C enter in drying tower with vaporific mixing of materials, material microparticle aqueous evaporates, bulky grain enters bottom drying tower, fluidized dryer is entered by discharging opening, now oarse-grained aridity is about 0.5, the mixture of granule and air is discharged from discharge pipe, still fluidized dryer is entered from the air intake of fluidized dryer, the temperature of this mixture is about 70-90 DEG C, in fluidized dryer, further drying is carried out to bulky grain, oarse-grained aridity is made to be reduced to less than 0.3.
