Abstract
The utility model discloses a spouting and pelletizing device with a stable wind direction. The spouting and pelletizing device comprises a pelletizing tower, wherein a cone base is arranged at the lower end of the pelletizing tower; an air outlet is arranged at the lower end of the cone base; a discharge hole is formed at the lateral wall of the cone base; a blow-off nozzle is arranged at the lower end of the cone base and is the blow-off nozzle at the upper end of a blow dryer; the blow-off nozzle of the blow dryer is a circle of sawteeth; and the sawteeth can be teeth of various shapes, preferably triangular teeth. The pelletizing and blowing device prevents the wind from being scattered after being blown out by a certain distance from the blow dryer in crystallizing and pelletizing processes, and prevents the material from directly contacting with the tower wall, so as to generate adhesion phenomenon; the sawteeth-shaped teeth are evenly distributed along the circumference of the blow dryer; the blown wind is evenly dispersed by the even and equal triangular teeth; and the wind direction and angle are symmetrical with one another, so as to evenly pelletize. Waste of the material in the pelletizing process is avoided.
Description
Technical field
The present invention relates to a kind of Granulation Equipments technical field: be that the feed liquid that will melt enters granulation tower by the wind atomizing that is blown into, circulating cooling forms particle and constantly glues and grow up again in granulation tower, the method that the granule materials that forms is discharged from discharging opening at last, be particularly suitable for the granulation such as magnesium chloride, calcium chloride, caustic soda field, particularly a kind of wind direction is stablized the device of spray-fluidized granulation.
Background technology
The spout granulation device of existing controllable granularity, granulation tower is arranged, the granulation tower upper end is with air-vent and air-introduced machine, the granulation tower hypomere is with boring the end, under cone, end is with blowing mouth, and blowing mouth has the conduit that imports liquid charging stock, and conduit is communicated with the liquid charging stock container, sidewall is with secondary air inlet, and the cone downside wall is with discharging opening.Concentrate and to be blown into distinguished and admirable side because discharging opening is in blowing mouth, the discharging opening inboard is negative pressure, and discharging opening is continuous air intake also.The present invention makes the method for smooth enwrapped granule like this, to become the raw material of spray pattern to blow into into granulation tower from the entrance of the beneath end of granulation tower cone with wind, the particle of cooling formation also is circulated back to very soon cone and mixes with the atomized feed that constantly enters at the end, the raw material of the sticky complex atomization that constantly circulates up and down and continuous increase.When the particle weight that circulation increases reached the air intake negative pressure that can overcome granulation tower lower end cone downside wall discharging opening, the grain flow of increase was just discharged from discharging opening during through discharging opening.The wind that the granule that does not reach certain particle size is just entered from discharging opening during by discharging opening is blown into and continues circulation in tower and increase.This device is mainly used in the spout granulation field, and the air outlet in existing Granulation Equipments is circular air port, wind after air outlet, the very bad control of wind direction, the air port has Divergent Phenomenon; If control bad wind direction, wind direction is unstable, and in the adhesion immediately of material contact tower wall, and granulation is inhomogeneous.
Summary of the invention
The present invention is intended to stablize the air outlet wind direction, solves material adhesion tower wall phenomenon and the even problem of granulation in the crystallization granulation process, and a kind of wind direction stabilising arrangement of granulation blowing is provided.
For addressing the above problem, wind direction stabilize spout prilling granulator of the present invention has granulation tower, the granulation tower upper end is with air-vent and air-introduced machine, the granulation tower sidewall is with secondary air inlet, the granulation tower lower end is with boring the end, the cone downside wall is with discharging opening, under cone, end is with blowing mouth, blowing mouth has the conduit that imports liquid charging stock, conduit is communicated with the liquid charging stock container, it is characterized in that: under cone, end is with the air duct of blowing, and air duct has conduit or the jet pipe that imports liquid charging stock, and the air outlet of air duct is the sawtooth in a week.Under cone, end is the blowing mouth of air duct upper end with blowing mouth, and the blowing mouth of air duct is the sawtooth in a week.Sawtooth can be the tooth of various shapes, is preferably lance tooth.Concentrate and to be blown into distinguished and admirable side because discharging opening is in blowing mouth, the discharging opening inboard is negative pressure, and discharging opening is continuous air intake also.For the ease of processing, the zigzag indentation circle in a week and with the welding of the outlet air end of air duct.Such granulation blowing device in the crystallization granulation process, keeps wind to blow out rear certain distance from air duct and does not disperse, and has avoided direct the contact phenomenon that then stick together of material with the tower wall; Described jagged tooth circumferentially evenly distributes along air duct.The lance tooth that evenly equates makes the wind Uniform Dispersion that blows out, and wind direction, angle are symmetrical, thereby granulation is even.
Because being provided with the surface at the air outlet place of former circular edges mouth, the present invention has continuous ripple profile of tooth, indentation, best homogeneous phase equilateral triangle tooth, the wind direction stabilising arrangement of indentation, after wind is blown out from air duct, keep certain distance not disperse, the wind post is stable, guarantee the direction of motion of material, avoided material to contact with the direct of tower wall; And dispersion, angle, air quantity are symmetrical, make granulation even.
Description of drawings
Fig. 1 is profile of the present invention, and the conduit and the electric fan that import liquid charging stock are not cut open.
The specific embodiment
A kind of wind direction stabilize spout prilling granulator of the present invention has granulation tower, the granulation tower upper end is with air-vent 1 and air-introduced machine, the granulation tower hypomere is with boring the end, under cone, end is with blowing mouth, blowing mouth has the conduit 5 that imports liquid charging stock, and conduit is communicated with the liquid charging stock container, and sidewall is with secondary air inlet 2, it is characterized in that: the cone downside wall is with discharging opening 3, and under cone, end is with the air outlet 7 of granulation Blowing drum.The air outlet of this air duct upper end and a surface are for there being the ripple tooth, and the circle 6 of indentation is connected.The circle 6 of indentation is connected with former air outlet 7, makes the wind that blows out the purling stream that fluctuates not occur, wind direction is stable.Cooling granulation magnesium chloride or calcium chloride, magnesium chloride advance 150 ℃, tower (calcium chloride advances 170 ℃, tower), and 40 ℃, tower wall blows into 130 ℃ of post crystallizations of cold wind, and iterative cycles carries out granulation.The air outlet that indentation is housed is stable, keep disperseing after certain distance, and dispersion, angle, air quantity is symmetrical, avoid magnesium chloride or calcium chloride adhesion tower wall, make granulation uniform and stable.
