Abstract
The utility model provides a kind of spray dryer tower wall scavenging conduit, including the body set along tower wall bus, the body is provided with the slit being axially staggered, wherein, the top of the top slit is flushed with the top of tower wall, and the bottom of bottom slit is flushed with the bottom of tower wall.The purging scope of the utility model scavenging conduit can cover the whole tower wall of spray dryer, can all remove the powder adsorbed in tower wall.
Description
Technical field
The utility model is related to spray dryer field, more particularly to a kind of spray dryer tower wall scavenging conduit.
Background technology
Spray dryer is one kind of continous way atmospheric dryer, for by liquid material atomisation and making it be connect with hot-air
Touch and dried.When being dried, hot-air is in the shape of a spiral evenly into hothouse, and feed liquid is through the atomizer at the top of tower body
Rotating spraying is into imperceptible powder, then with hot-air current contacting, and it is finished product to be dried within the extremely short time, and finished product is by arranging
The air-flow discharge bottom of towe that blower fan is extracted.
As shown in figure 1, because the powder 2 formed in drying tower is special tiny, and some powders 2 have viscosity and electrostatic
Effect, often adsorbs in tower wall 1 and produces the packing phenomenon of powder 2, and main use sets along the bus of drying tower tower wall 1 at present
The scavenging conduit 3 (as shown in Figure 2) put is purged to it.The structure of traditional tower wall scavenging conduit is as shown in figure 3, longitudinal on its body
A row aperture is interval with, during work, scavenging conduit 3 is made under the drive of rotating mechanism (not shown) to justify thereunder along tower body diameter
Zhou Yundong, and the pressure-air in its pipeline is purged through aperture to the powder 2 adsorbed in tower wall.However, due to one
There is a little powders the factors such as viscosity and electrostatic interaction to be difficult to be purged, thus striped as shown in Figure 4 can be formed in tower wall
Powder vestige 21, is commonly called as " zebra stripes ".The powder of these residuals is toasted on high temperature for a long time, can be produced rotten and be lumpd, weight
Power can block conveying airduct after coming off.
Utility model content
For above-mentioned the deficiencies in the prior art, the utility model provides a kind of spraying that can be comprehensively purged to tower wall
Drying machine tower wall scavenging conduit.
To achieve these goals, the utility model is adopted the following technical scheme that：
A kind of spray dryer tower wall scavenging conduit, including the body set along tower wall bus, the body are provided with along axle
To staggered slit, wherein, the top of the top slit is flushed with the top of tower wall, the bottom of bottom slit and tower wall
Bottom flush.
Preferably, the slit that the body is axially staggered provided with two row.
In summary, the slit that the utility model is axially staggered by being set on the body of scavenging conduit, and make
The top of most upper slit is flushed with the top of tower wall, most descends the bottom of slit to be flushed with the bottom of tower wall, so that scavenging conduit
Purging scope can cover whole tower wall, powder in tower wall will be adsorbed and all removed, thoroughly solved residual in tower wall
The problem of staying " zebra stripes ".

Embodiment
Below in conjunction with the accompanying drawings, preferred embodiment of the present utility model is provided, and is described in detail.
Spray dryer tower wall scavenging conduit of the present utility model includes the body set along the bus of drying tower tower wall 1, with showing
Have unlike technology, as shown in figure 5, not setting longitudinally spaced aperture on body, but be provided with two row and hand over vertically
Mistake arrangement slit 31', wherein, the top slit 31' top is flushed with the top of tower wall 1, most descend slit 31' bottom and
The bottom of tower wall 1 is flushed, so as to form continuous air curtain so that the purging scope of scavenging conduit can cover whole tower wall 1, can be by
The powder adsorbed in tower wall 1 is all removed, and thoroughly solves the problem of remaining " zebra stripes " in tower wall.For client's different dry
The need for dry machine type, the caliber and purge air quantity of convertible scavenging conduit.
It should be noted that, although set the slit above and below straight-through body equally to form continuous air curtain, but this practicality is new
Type does not use this scheme, but employs staggered slit 31' to realize purpose, and this is to ensure scavenging conduit
Intensity, because what is be passed through in body is pressure-air, easily splits if the slit above and below a straight pipe body is set on body.Can
See, the utility model is to have considered many factors, the creative work through inventor is designed.
In addition, as shown in fig. 6, scavenging conduit 3 preferably makes the center line mistake of the slit and scavenging conduit on its body when mounted
An angle beta is opened, so that there is the pressure-air blown out in slit shovel to blow effect, is so easier to remove the powder in tower wall
Body.
Above-described, preferred embodiment only of the present utility model is not limited to scope of the present utility model, this
Above-described embodiment of utility model can also make a variety of changes.I.e. every claims according to the present utility model application and
Simple, equivalent changes and modifications that description is made, fall within the claims of the utility model patent.This
The not detailed description of utility model is routine techniques content.
Claims (2)
1. a kind of spray dryer tower wall scavenging conduit, including the body set along tower wall bus, it is characterised in that on the body
Provided with the slit being axially staggered, wherein, the top of the top slit is flushed with the top of tower wall, the bottom of bottom slit
End is flushed with the bottom of tower wall.
2. spray dryer tower wall scavenging conduit according to claim 1, it is characterised in that the body is provided with two row edges
