Description
Technical field
The utility model is related to drying tower technical field, and in particular to a kind of spray drying tower.
Background technology
Spray drying is a kind of method that systematization technique is applied to dry materials, in the drying chamber by solvent or diluent through atomization
Afterwards, then in the contact with hot-air, moisture rapid vaporization obtains dry products.The method dries directly solution, emulsion
Powdering or particulate preparation, can save the processes such as devaporation, crushing.By mechanism, the material that need to will be dried is dispersed into very
The thin particulate as mist, increases moisture evaporation area, accelerates drying process, and makes itself and hot air, will in moment
Most of moisture is removed, and the solid matter in material is dried to powder.Spray drying tower can spray into the material of solution state
In spray drying tower, discharged after dry materials in solid powder state.It is widely used in biological pesticide, medicine, food microorganisms
Drying.
Existing spray drying tower, which has non-uniform temperature above and below in drying tower, makes the poor lamp defect of drying effect.
The content of the invention
In order to solve the above technical problems, the purpose of this utility model is the provision of a kind of spray drying tower, it is existing to solve
There are the defects such as drying effect is poor, temperature distributing disproportionation is even.
To achieve the above object, a kind of spray drying tower of the utility model, including a drying tower body, a filter screen are fixed on
The dry tower body and the dry tower body is separated into interval and interval once on one, a feed liquor shower nozzle is located at the lower area
Between, one first air inlet, one second air inlet and one the 3rd air inlet be located at the feed liquor shower nozzle below and in the vertical direction
Mutually stagger setting, second air inlet is located at the lower interval homonymy, first air inlet with the feed liquor shower nozzle
It is located at the lower interval opposite side relative with the feed liquor shower nozzle with three air inlet, the upper interval top has one
Exhaust outlet, the exhaust outlet is connected by a condenser pipe with a catch box, and the lower interval bottom is provided with a rewinding case.
It is preferred that, in the vertical direction, second air inlet is located at first air inlet and the 3rd air inlet
Between.
It is preferred that, first air inlet and the 3rd air inlet pass through a secondary heater and one by a three-way pipe
One end connection of second blower fan, the other end of second blower fan is connected with one second air cleaner.
It is preferred that, second air inlet is connected by a primary heater with one end of one first blower fan, and described first
The other end of blower fan is connected with one first air cleaner.
It is preferred that, in the vertical direction, difference in height between first air inlet and second air inlet with it is described
Difference in height between second air inlet and the 3rd air inlet is identical.
Compared with prior art, its advantage is the utility model：A kind of spray drying tower of the present utility model, it is described
First air inlet, second air inlet and the 3rd air inlet are located at feed liquor shower nozzle lower section and in the vertical direction phase
Mutual setting of staggering, is uniformly distributed in the lower interval of the dry tower body, makes the hot-air gushed out from them uniform
Be distributed in the lower interval upper, middle and lower region, overcome non-uniform temperature above and below existing spray drying tower internal cause, and
Powder is caused to rupture the poor lamp problem of impaired, drying effect, so as to improve the quality of powder.Moisture vaporizes change after heated in feed liquid
Into vapor vapor, the vapor vapor can be discharged rapidly from the exhaust outlet, prevent the vapor water from steaming
Gas, which is stranded in the spray drying tower, influences the drying of powder, so as to further improve drying effect.The filter screen only allows gas
Body and vapor vapor pass through, and powder can be prevented to cause powder to be lost in into the upper interval.
Brief description of the drawings
Fig. 1 is a kind of structural representation of spray drying tower of the utility model.
Embodiment
To describe technology contents, construction feature, institute's reached purpose and effect of the utility model in detail, reality is hereby enumerated below
Apply example and coordinate accompanying drawing to be explained in detail.
