Description

A kind of atlapulgite drying system
Technical field
The present invention relates to drying system, be specifically related to a kind of atlapulgite drying system.
Background technology
Atlapulgite is to be raw material with clay (mainly being bentonite), and through the adsorbent that operations such as activation processing such as persulfuric acid, rinsing, Separation of Solid and Liquid, oven dry, grinding are made, outward appearance is off-white powder, odorless, tasteless, nontoxic, absorption property is very strong, can be adsorbed with color substance, organic substance.The easy moisture absorption was placed for a long time and can be reduced absorption property in air.Be mainly used in oil catalysis and mineral oil, the decolouring of plant wet goods.Main mass parameter has: activity degree, percent of decolourization, free acid content etc.
The atlapulgite drying system mainly adopts rotary drum drying machine to connect apparatus for feeding and discharging equipment at present.Its form that generally adopts is the downflow type drying, and wet stock enters drying machine and just contacts with the higher drying medium of temperature, and the initial stage, dry motive force was bigger, and with the rising of temperature of charge, the temperature of drying medium reduces later on.So it is suitable to the less demanding material of final water content (being degree of drying).The dry material temperature of discharging is lower, is convenient to transportation.But from producing dust, thinner material is taken away by air-flow easily, and Dust Capacity is bigger.Be exactly specifically the wet stock of atlapulgite from the hot blast inlet feed, treat to arrive material outlet after hot blast and the atlapulgite heat exchange drying.The atlapulgite exit is the hot-blast outlet place just.Make atlapulgite be taken out of in the exit much like this, and to evaporate moisture in the atlapulgite wet stock, hot blast temperature that need be when just entering rotary drum drying machine is higher, has both needed a large amount of heats, though transpiring moisture so both had been unfavorable for that environmental protection was not energy-conservation yet so faster.
Dryer is evenly distributed on various piece and drying medium excellent contact on the rotating cylinder cross section in order to increase material, and the solid lifting blade of a large amount of erection weldings has evenly distributed in cylindrical shell.Lifting blade is one of accessory very important in the dryer equipment, and the design of lifting blade and substep directly influence this drying effect.Comparatively similar with the rotary drum drying machine of the application of atlapulgite drying system of the present invention, as Chinese patent (application number: 200720036850.2) described a kind of rotating cylinder horizontal drying machine, comprise air blast, the high-boiling stove, elevator, feed bin, the frequency control belt feeder, tremie pipe, rotating cylinder, lifting blade, transmission system, dust pelletizing system, air-introduced machine, the discharging cover, blanking device, belt conveyer, it is characterized in that described lifting blade is " L " shape, be evenly distributed on the outer cylinder inwall of rotating cylinder, secondary lifting dispersing device also is housed on the inner cylinder outer wall of rotating cylinder; The large and small gear of transmission system is pick-off gear; Described dust pelletizing system includes cyclone dust collectors, air box impulse bag-type dust-precipitator two-stage dust removal.Described high-boiling stove also can adopt Coal powder spray stove, conventional oven hand-manipulated.Utilize " L " shape lifting blade and secondary lifting dispersing device to make material can evenly break up oven dry, adopted two-stage dust removal and pick-off gear simultaneously.This dryer specifically is applied in the atlapulgite drying system also need make improvement, and its structure is too complicated.
Summary of the invention
The objective of the invention is, provide a kind of energy-conservation, reduce airborne dust and the higher atlapulgite drying system of evaporation efficiency.For realizing that purpose of the present invention is by following technical measures:
A kind of atlapulgite drying system comprises hot-blast stove and drying kiln, and the drying kiln two ends are respectively feed end and exhaust end; Described hot-blast stove places the exhaust end of drying kiln, is provided with the air blast of hot blast being sent into drying kiln at exhaust end, or is provided with air-introduced machine at the feed end of drying kiln; Make in the drying kiln material direction of transfer opposite with the hot blast direction of transfer.
For better utilization heat energy, energy savings makes evaporation efficiency higher, and described drying kiln comprises inner heat-insulation layer and outside surrounding layer.Described drying kiln is horizontal cylinder, for hot blast and material have bigger contact area, improve evaporation efficiency, be evenly distributed with at least one group of lifting blade vertically at inwall, and the adjacent lifting blade on the same cross section of inwall is different with the angle of described drying kiln tangential direction.For material is slowly pushed forward, be convenient to regulate the drying time of material in drying kiln, described drying kiln is and is in tilted layout, and described feed end is higher than exhaust end, and gradient is between 1~10 degree.
For this system of better control, the feed end of described drying kiln is provided with the charging motor; Described hot-blast stove is provided with into coal motor; Described charging motor, advance the thermometer that arranges on coal motor, the drying kiln and connect controller.Controller is passed signal back by thermometer, regulates charging motor and the speed of advancing the coal motor, keeps required hot blast temperature.Further, described hot-blast stove is the reciprocating fire grate combustion furnace.
In order better to reduce airborne dust, the charging port of described drying kiln is provided with the lock conch and revolves reamer.The feed end of described drying kiln is provided with device for recovering powder.Described device for recovering powder comprises cyclone collector and sack cleaner.
The invention has the beneficial effects as follows: (1) is energy-conservation.The hot blast direction of transfer is opposite with the throughput direction of atlapulgite on the drying kiln, be that discharge end is exactly the initiating terminal that hot blast transmits, hot blast with the atlapulgite heat exchange after, the atlapulgite of oven dry is discharged, hot blast continues forward and the not fully atlapulgite heat exchange of oven dry, has taken full advantage of heat.Avoid in the prior art, hot blast and oven dry material are discharged wasted heat together.And drying kiln wall material is insulation material, and can make hot blast arrive material feed end temperature by controller to be low to moderate 40~50 ℃, and the material discharge temperature does not have wasted heat substantially at 60~80 ℃ yet.(2) reduce airborne dust.At the exhaust end of drying kiln, hot blast with the atlapulgite heat exchange after, the atlapulgite of oven dry is discharged, some airborne dusts are taken away in the hot blast transmission, and fully the atlapulgite of oven dry does not have suction-operated to airborne dust, more near feed end, moisture content of material is more high, and it is more obvious then to adsorb airborne dust.And be provided with cyclone collector and sack cleaner and charging port and discharge port at the feed end of drying kiln and all adopt sealing device.The sealing device of charging port revolves reamer for the lock conch.The minimizing of these technical characterictic maximum possible airborne dust.(3) evaporation efficiency is higher.The ingenious design of lifting blade makes the contact area of hot blast and material increase greatly, and evaporation efficiency is higher.
Generally speaking, the present invention is a kind of energy-conservation, reduces airborne dust and the higher atlapulgite drying system of evaporation efficiency.
