Technical field
The present invention relates to a kind of dry bed apparatus more particularly to a kind of dry bed apparatus of no nozzle.
Background technique
In dry bed apparatus, high-temperature hot-air is generallyd use as heat source, the water-containing materials to enter bed are dried
Processing, and then obtain dried solidss.In the drying bed course of work, dry slurry usually enters drying bed via nozzles spray
It is interior, since temperature is high in bed, it is easy to generate fouling, blocking on injector arrangement, thus cause that equipment failure rate is high, reliability
Substantially reduce, existing drying bed is both needed to periodically to shut down, cleaning, great work intensity using nozzle arrangements form, plant maintenance at
This is higher.
Summary of the invention
The purpose of the present invention is to provide a kind of no nozzle fluidized bed drying equipments, to solve in existing dry bed apparatus
Dry slurry is entered in drying bed by nozzles spray, is easy to cause fouling on nozzle, blocking, equipment failure rate is high, reliability is big
It is big to reduce, need regular stop cleaning, the higher technical problem of cost of equipment maintenance.
In order to solve the above technical problem, the present invention provides a kind of no nozzle fluidized bed drying equipments, it is characterised in that: packet
It includes drying bed and conveys the feeding lines of dry carrier, the bottom of the drying bed is equipped with dry-heat air entrance, the top of drying bed
Portion is exported equipped with lack of gas, is provided with air distribution plate above drying bed bottom, dry-heat air entrance；
The feeding lines are arranged in above air distribution plate, the emulsion zone of the dry carrier in drying bed lower part, and the feeding lines are in water
Square to two sides be equipped at intervals with discharge hole.
Preferably, the feeding lines include main pipeline and the row's subtube connecting with main pipeline, and the discharge hole is set
In the two sides of subtube.
Preferably, the opening direction of the discharge hole is downward, and the opening of discharge hole and the angle of horizontal plane be 45~
90°。
Preferably, the spacing of the discharge hole is 200~500mm, and the aperture of discharge hole is 2~6mm.
Preferably, round hole or elongate strip hole are offered on the air distribution plate, the percent opening of air distribution plate is 10%~20%.
Preferably, feeding lines setting is above the air distribution plate at 200~400mm.
Preferably, be positive rotary table at the top of the drying bed, and the bottom of drying bed is inverted round stage.
Compared with prior art, the features of the present invention and no nozzle fluidized bed drying equipment of the invention is had the beneficial effect that
Feeding lines are arranged in the emulsion zone of fluidisation state, only by the internal flow feature for making full use of the drying bed with heat carrier
In the pipe side opening of feeding lines, under lower discharge pressure, using the continuous shock of dry carrier, efficiently avoid out
Fouling blockage at hole substantially increases equipment reliability of operation to realize noseless drying bed water supplement technology.
