Abstract
The invention discloses a wind direction stable spraying pelleting device which is provided with a pelleting tower. A taper bottom is arranged at the lower end of the pelleting tower, an air outlet is arranged at the lower end of the taper bottom, and a material discharge port is arranged on a lateral wall of the taper bottom. An air blowing port arranged at the lower end of the taper bottom is an air blowing port arranged at the upper end of an air cylinder, the air blowing port of the air cylinder is a ring of sawteeth which can be various shapes, and the sawteeth has better to be triangular teeth. The spraying pelleting device keeps wind to not disperse in a certain distance after blowing out from the air cylinder in a crystallization pelleting process, and avoids adhesion caused by direct contact between materials and a tower wall. The sawtooth-shaped teeth are evenly distributed along the circumferencial direction, even and equal triangular teeth enable blown wind to evenly disperse, and wind directions and angles are mutually symmetrical to achieve even pelleting. Waste of the materials in a pelleting process is avoided.
Description
Technical field
The present invention relates to a kind of Granulation Equipments technical field: be the wind atomizing entering granulation tower of feed liquid through being blown into fusing; Circulation cooling formation particle is also constantly sticking in granulation tower grows up again; The method that the granule materials that forms is discharged from discharging opening at last; Be particularly suitable for granulation fields such as magnesium chloride, calcium chloride, caustic soda, particularly a kind of wind direction is stablized the device of spray-fluidized granulation.
Background technology
The spout granulation device of existing controllable granularity has granulation tower, and the granulation tower upper end has air-vent and air-introduced machine; The granulation tower hypomere has the awl end; End has blowing mouth under the awl, and blowing mouth has the conduit that imports liquid charging stock, and conduit is communicated with the liquid charging stock container; Sidewall has the secondary air mouth, and the awl downside wall has discharging opening.Blowing mouth is concentrated to be blown into distinguished and admirable side because discharging opening is in, and the discharging opening inboard is negative pressure, the air intake that discharging opening is also continuous.The present invention makes the method for smooth enwrapped granule like this; To become the raw material of spray pattern to blow into from the inlet of the beneath end of granulation tower awl with wind into granulation tower; The particle that cooling forms also is circulated back to the awl end very soon and mixes the constantly raw material of the sticking multiple atomizing of circulation and continuous increase up and down with the atomized feed that constantly gets into.When the particle weight that circulation increases reaches the air intake negative pressure that can overcome granulation tower lower end awl downside wall discharging opening, just discharge during the grain flow process discharging opening of increase from discharging opening.The granule that does not reach certain particle size just is blown into by the wind that gets into from discharging opening during through discharging opening and continues circulation in the tower and increase.This device is mainly used in the spout granulation field, and the air outlet in the existing Granulation Equipments is circular air port, wind after the air outlet air-out, the very bad control of wind direction, the air port has the phenomenon of dispersing; 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, and the granulation tower upper end has air-vent and air-introduced machine; The granulation tower hypomere has the awl end, and end has blowing mouth under the awl, and blowing mouth has the conduit that imports liquid charging stock; Conduit is communicated with the liquid charging stock container; Sidewall has the secondary air mouth, it is characterized in that: the awl downside wall has discharging opening, and end has blowing mouth under the awl.End has the blowing mouth that blowing mouth is the air duct upper end under the awl, and the blowing mouth of air duct is the sawtooth in a week.Sawtooth can be the tooth of different shape, is preferably lance tooth.Blowing mouth is concentrated to be blown into distinguished and admirable side because discharging opening is in, and the discharging opening inboard is negative pressure, the air intake that discharging opening is also continuous.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 the back 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; Said jagged tooth circumferentially evenly distributes along air duct.The lance tooth that evenly equates evenly disperses the wind that blows out, and wind direction, angle are symmetrical, thereby granulation is even.
Because the present invention is provided with the surface at the air outlet place of former circular edges mouth and has continuous ripple profile of tooth, indentation, preferably 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; Guaranteed 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 a profile of the present invention, and the conduit and the electric fan that import liquid charging stock are not cut open.
Specific embodiment
A kind of wind direction stabilize spout prilling granulator of the present invention has granulation tower, and the granulation tower upper end has air-vent 1 and air-introduced machine, and the granulation tower hypomere has the awl end; End has blowing mouth under the awl; Blowing mouth has the conduit 5 that imports liquid charging stock, and conduit is communicated with the liquid charging stock container, and sidewall has secondary air mouth 2; It is characterized in that: the awl downside wall has discharging opening 3, and end has the air outlet 7 of granulation Blowing drum under the awl.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 ℃ in tower (calcium chloride advances 170 ℃ in tower), and 40 ℃ on tower wall blows into 130 ℃ of post crystallizations of cold wind, and granulation is carried out in circulation repeatedly.The air outlet air-out that indentation is housed is stable, keep disperseing behind the certain distance, and dispersion, angle, air quantity is symmetrical, avoid magnesium chloride or calcium chloride adhesion tower wall, make granulation uniform and stable.
Claims (4)
1. a wind direction stabilize spout prilling granulator has granulation tower, and the granulation tower upper end has air-vent and air-introduced machine, and the granulation tower sidewall has the secondary air mouth, and the granulation tower hypomere has the awl end, and the awl downside wall has discharging opening; It is characterized in that: end has the air duct of blowing under the awl, 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.
