Description
Technical field
The utility model relates to the antiseized wall device of a kind of small compact radial spray drying tower, belongs to food industry mechanical device technical field.
Background technology
At present, spraying dry has become a kind of main drying mode, and equipment and technology is very ripe, and its advantage is that drying time is short, and product moisture is low, and quality is good, is particularly suitable for heat sensitive material drying.Spray drying technology is very ripe, and spray pattern has pressure type and centrifugal.Pressure type needs high pressure homogenizer as raising pressure, and at drying tower top, ejection is formed vaporific by contacting with hot blast, wink-dry.Centrifugal sprinkler does not need high pressure, but needs motor or compressed air to drive the rotation of centrifugal energy nozzle, thus feed liquid is formed vaporific, then contacts with hot blast, wink-dry.The advantage of press spray drying tower is that output is large, be not easy sticky wall, but tower body height is higher.The advantage of Centrafugal spray drying tower is that equipment investment is few, and operating cost is low, but easily causes wall sticking phenomenon, is applicable to the drying of inviscid material, and the low diametric requirements of height of tower body is large simultaneously.Therefore many employing pressure type drying towers in large-scale production, prototype version equipment many employings Centrafugal spray drying tower.
The hot wind inlet of Centrafugal spray drying tower generally all enters along spiral air channel at tower top, blows out obliquely through deep bead, fully contacts, complete drying with the feed liquid after atomization.The reason that atomizer tower easily glues wall is that feed liquid is vaporific by formation level after centrifugal energy nozzle, fully contacts, reach wink-dry with downward hot blast.But due to inertia reason, also have partly atomized feed liquid not by hot blast band at the bottom of tower, but continue horizontal movement, arrive the tower wall of drying tower, due to the non-bone dry of this material, therefore stick to Ta Bishang, along with the increase of subsequent material, cause wall sticking phenomenon.If reduce the rotating speed of centrifugal energy nozzle, feed liquid can not form vaporific, causes uneven drying again, forms particle, and product moisture controls uneven.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of small compact radial spray drying tower antiseized wall device.
The technical solution of the utility model is as follows:
The antiseized wall device of a kind of small compact radial spray drying tower, comprise warm-air pipe, blast pipe, air intake valve, distributor and centrifugal energy nozzle, described distributor to be arranged on inside drying tower roof and to be connected with blast pipe, distributor is provided with multiple aperture, distributor is positioned at the top of centrifugal energy nozzle, and described blast pipe is run through drying tower roof and is communicated with warm-air pipe by air intake valve.
Preferably, described distributor is an annular distributor, and the tube wall of annular distributor is evenly provided with multiple aperture.
Preferably, the aperture of described aperture is 0.5-3mm.
Preferably, the diameter of described annular distributor is 0.3-0.6 times of drying tower diameter.
Preferably, the center of circle of described annular distributor is positioned on the perpendicular bisector of drying tower tower body.The benefit of this design is, by annular distributor being placed in the center position of drying tower, making annular distributor equal with the distance of drying tower tower wall, can guarantee that feed liquid does not fly to Ta Bi to the full extent, prevent sticky wall.
Preferably, being centrally located at directly over centrifugal energy nozzle of described annular distributor.The benefit of this design is, centrifugal energy nozzle is positioned at immediately below annular distributor center, feed liquid from centrifugal energy nozzle out time the hot blast that can discharge with the aperture distributor equably fully contact, and within the scope that the feed liquid of discharging from centrifugal energy nozzle can be made to move down at hot blast, avoid occurring sticky wall as far as possible.
During use, hot blast enters from warm-air pipe, open air intake valve, be communicated with warm-air pipe and blast pipe, hot blast enters in distributor from blast pipe, then evenly blow out downwards from the aperture of distributor, feed liquid is from the backward lower ejection of centrifugal energy nozzle atomization, and the hot blast of now evenly blowout downwards, drives the feed liquid be atomized to move downward, and fully contact with downward hot blast, reach the object of wink-dry.
The beneficial effects of the utility model are:
In the local space that the antiseized wall device of the utility model makes hot blast be evenly distributed in drying tower, make wind direction, wind-force evenly blows out downwards, can the feed liquid after atomization be confined within the scope of lower blowing hot-air, the feed liquid of atomization drying can be avoided to a great extent to fly to Ta Bi, occur the situation of sticky wall.Meanwhile, distributor can make wind evenly blow out downwards, can ensure the uniformity of all directions, makes the evenly abundant of the feed liquid drying after atomization, correspondingly leads to height drying effect.
