Description
Technical field
This utility model relates to water-soluble fertilizer technical field of processing equipment, is specifically related to a kind of production Water soluble fertilizer spray drying tower.
Background technology
Spray drying is a kind of method that systematization technique is applied to dry materials, in hothouse by solvent or diluent after atomization, with in the contacting of hot-air, moisture rapid vaporization, i.e. obtain dry products.This method can directly make solution, emulsion be dried to powdery or particulate preparation, can save the operation such as devaporation, pulverizing, and spray drying process has pressure spray dryer method, centrifugal spray drying method, pneumatic spray drying method.
Existing spray drying technology, it is not provided with distribution grid in spray drying tower wind inlet section cone, in entrance cone, the wind speed of dry-heat air reduces with the increase of spray drying tower cone diameter, when the slurry atomized drop sprayed with high-pressure nozzle contacts, due to wind speed weaken, caused by the factor such as skewness, air film can not surround rapidly drop, causes drop diffusion rate in air film to reduce, liquid can not rapid vaporization, make drying capacity reduce；And hot blast speed weakens, it is impossible to change the direction of motion of atomizer ejection cone diffused slurry droplet, easily move to drying tower barrel, cause viscous wall.
Utility model content
For the deficiencies in the prior art, this utility model provides one to produce Water soluble fertilizer spray drying tower, and device structure is simple, has excellent drying effect to Water soluble fertilizer.
The technical solution adopted in the utility model is as follows:
A kind of production Water soluble fertilizer spray drying tower, including tower casing, top cover, the cone end, tower casing upper end is provided with top cover, air inlet lines it is communicated with on top cover, equipped with air heater inside air inlet lines, the upper end in the tower intracavity portion of tower casing is provided with helicla flute nozzle, feed liquid pipe is connected through tower casing with helicla flute nozzle, helicla flute nozzle is directed downward, the cone end it is provided with bottom tower casing, more than one baffle plate vertically it is provided with on the inwall of described tower casing, the cone end, is provided below cyclone separator, finished product storage tank it is provided with bottom cyclone separator, backwind tube it is provided with in cyclone separator, backwind tube extend into Ta Nei and is in communication with the outside through the cone end.
Preferably, described air inlet lines end is equipped with air filter.
Preferably, described air heater side is provided with thermometer.
Preferably, described tower casing is provided with manhole and visor.
Preferably, downward-sloping 45 ° along the inwall of tower casing of described baffle plate, the vertical dimension between adjacent screen is the 1/5 of tower casing height.
Preferably, described baffle plate is uniformly distributed on the inwall of tower casing.
Preferably, described baffle plate is rectangle.
This utility model beneficial effect: it is uneven that this utility model can reduce spray drying tower internal gas flow field distribution by the baffle plate vertically arranged on the inwall of tower casing, improve turbulivity, and then improve spray drying tower to the drying area of feed liquid and drying efficiency；Air-flow is downward along cyclone separator, and cyclone separator increases gas-flow resistance, makes the dry products that density is big be settled down to downwards finished product storage tank, gas solid separation, and the little powdery product of density is discharged with backwind tube.This device fabrication is easy, and operation is stable, can well coordinate the linking work of upstream and downstream technique.This production Water soluble fertilizer spray drying tower is reasonable in design, simple in construction, safe and reliable, easy to use, be easily maintained, have good value for applications.
