Abstract
The invention discloses a kind of method for recycling spray drying tower tail powder, spray drying tower powder tail gas passes through cyclone dust collectors, expansion chamber, bag filter, and the tail powder in tail gas is collected；Tail powder is homogeneously added into the hot air pipe of spray drying top of tower through powder feeder；Tail powder is blown into spray drying tower by hot wind in hot air pipe, is mixed and made into powder in Ta Nei and the mud of atomization.The tail powder that the present invention collects, it is not required to plus aquation is at mud, but directly by tail dried bean noodles, penetrating spray drying tower and the mud of atomization remix and powder are made after dry, greatly reduce the evaporation capacity of moisture, powder yield is increased under same evaporated water, reduce energy consumption, to reduce the production cost of powder.
Description
Technical field
The present invention relates to the recycling of drying tower tail powder, the method recycled more particularly to spray drying tower tail powder.
Background technique
Present architectural pottery uses half dry-pressing formed production technology mostly, needs ceramic mud drying moisture is made
The powder of 6-9%.The flouring technology that most of producers use all is spray drying tower flouring technology, in spray-drying process,
Mud sprays into spray drying tower by plunger pump high pressure, allows dry in the short time after slurry atomization, and such atomizing particle is received naturally
It shortens round granular into, so that the powder of aqueous 6-9% be made, it is stand-by to be re-fed into filler bin.
During powder by spraying, due to containing tiny dust particles in the tail gas of spray drying tower, being cannot be direct
Discharge.Existing tail powder recycling is to first pass through the cleaners such as cyclone dust collectors, bag filter, expansion chamber for the powder in tail gas
Dirt powder collection gets off；Then the dust particles of collection are added into water, and stirred, be melted into mud, then mud is pumped into the big slurry of production
Pond sprays into the recycling of spray drying tower powder by normal operating and uses.In this removal process, due to being additionally incorporated when slurrying
Water, obtained mud moisture is generally up to 40%, in this way in spray drying tower powder, the powder of aqueous 6-9% obtained, at this
During a, need to evaporate a large amount of moisture, moisture evaporation consumes a large amount of thermal energy, energy consumption increased, to increase
Powder production cost.
Summary of the invention
The object of the present invention is to provide a kind of tail powder not slurryings, directly spray into returning for spray drying tower powder for tail dried bean noodles is dry
The method for receiving spray drying tower tail powder, whole process do not additionally incorporate water, just reduce the energy consumption of subsequent handling evaporation water, increase
The yield of powder reduces production cost.
The technical solution adopted by the present invention is that: a method of recycling spray drying tower tail powder, it is characterised in that: spraying dry
Dry tower powder tail gas passes through cyclone dust collectors, expansion chamber, bag filter, and the tail powder in tail gas is collected；Tail powder is through powder
Material dispenser is homogeneously added into the hot air pipe of spray drying top of tower；Tail powder is blown into spray drying tower by hot wind in hot air pipe
It is interior, powder is mixed and made into Ta Nei and the mud of atomization.
The powder feeder is mounted at the hot air pipe of spray drying top of tower.
The useless powder in part producing can be added in the tail powder, but useless powder has to cleaning sieving, removes large granular impurity.
The powder feeder is the compact spiral transporter of heat resistant and wear resistant material, can be adjusted and be added according to tail powder amount size
Enter amount, spiral conveyer uses the compact spiral transporter of heat resistant and wear resistant material, is in order to avoid the change of equipment caused by high temperature
Metal impurities influence powder quality is brought in shape and the friction reduced during charging into.
Aquation is not added into mud in tail powder Jing Guo the collections such as cyclone dust collectors, expansion chamber, bag filter by the present invention,
But directly by tail dried bean noodles, penetrating spray drying tower and the mud of atomization remix and are mixed and made into powder after dry, greatly reduce water
The evaporation capacity divided, powder yield is increased under same evaporated water, reduces energy consumption, to reduce the life of powder
Produce cost.
Detailed description of the invention
Fig. 1 is equipment structure chart of the invention；
In figure, 1 is deduster spray drying tower, and 2 be material storage tube, and 3 be trailer, and 4 be winch hoister, and 5 be powder feeder, 6
It is electric block, 7 be hot air pipe, and 8 be spray drying tower.
Specific embodiment
In order to better understand and implement the present invention, the present invention is further illustrated combined with specific embodiments below.
The present invention is a kind of method for recycling spray drying tower tail powder, and spray drying tower powder tail gas passes through cyclone dust removal
Device, expansion chamber, bag filter, the tail powder in tail gas are collected；Tail powder is homogeneously added into through powder feeder to be done by spraying
In the hot air pipe of dry top of tower, powder feeder is the compact spiral transporter of heat resistant and wear resistant material, is mounted on spray drying
At the hot air pipe of top of tower；Tail powder is blown into spray drying tower by hot wind in hot air pipe, in Ta Nei and the mud of atomization mixing system
At powder.
The useless powder in part producing can be added in tail powder of the present invention, but useless powder has to cleaning sieving, and it is miscellaneous to remove bulky grain
Matter.
The method of present invention recycling spray drying tower tail powder specifically:
The tail powder that deduster is collected is directly entered the closed material storage tube 2 of 1 lower section of deduster, has extension on material storage tube
Hook, under have feeding plate, after tail powder bucketful, be transported on winch hoister 4 with trailer 3, promoted by winch hoister to powder
The operating platform of batcher 5, then mentioned material storage tube on powder material machine hopper with electric block 6, by putting below material storage tube
Flitch is opened, and tail powder enters powder feeder hopper.The speed of 8 kilograms of fine powders was added by one minute for powder feeder, uniformly will
Fine powder is added in hot air pipe 7, then is blown into spray drying tower 8 by hot wind in hot air pipe and mist mud is mixed and powder is made.
The present invention directly mixes powder processed using dry powder and mist mud, and no extra band comes water evaporation, and spray drying tower
Yield limited by evaporated water, that is to say, that yield can be increased under the same evaporated water of recycling tail powder method originally,
The present invention can consume 10 tons of tail powder for one day, increase by 10 tons of powder yield, reduce the evaporation energy consumption of 8-9 tons of water, can save fine coal
1.2 tons, year save the cost 320,000.
Finally, it should be noted that above implement to be merely illustrative of the technical solution of the present invention, rather than its limitations；Although ginseng
According to previous embodiment, invention is explained in detail, those skilled in the art should understand that: it still can be with
It modifies the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features；And
These are modified or replaceed, the spirit and model of technical solution of various embodiments of the present invention that it does not separate the essence of the corresponding technical solution
It encloses.
