Cyclone hydraulic separators
Technical field
The utility model relates to a kind of cyclone hydraulic separators, belongs to gas-liquid separation device.
Background technology:As everyone knows, in aluminum oxide production process, can produce the indirect steam of carrying a large amount of alkaline mists secretly after the flash distillation of alkaline slip process flash vessel; The easy gas-liquid separation device of common at present employing comes the alkali lye in the separate vapour.This gas-liquid separation device by the collector tube of inverted cone-shaped, be fixed on the air inlet pipe that tangentially is communicated with it on this collector tube and constitute, the eddy current that when steam enters collector tube, can form, thus realize that alkali lye separates with steam; Yet, because collector tube is the inverted cone structure, steam in collector tube spin intensity a little less than, still have a considerable amount of alkali mists to discharge with steam, separating effect is relatively poor.
Summary of the invention:At the above-mentioned defective that exists in the prior art, the utility model aims to provide that a kind of volume is little, in light weight, simple in structure, the cyclone hydraulic separators of good separating effect.
To achieve these goals, the utility model by the following technical solutions: it comprises obconic collector tube, the air inlet pipe that is communicated with this collector tube; The upper port of collector tube has the spiral case separator that is communicated with it, this spiral case separator is made of the spiral case plate that is curled into the clockwork spring shape, the upper cover plate and the lower cover that are separately fixed at this spiral case plate top and bottom, the panel that is fixed on spiral case plate and upper cover plate and lower cover termination, the air inlet pipe that is fixed on this panel, be fixed with flange sleeve on the upper cover plate, the riser of fixedlying connected with this flange sleeve passes the spiral case separator and stretches in the collector tube.
Compared with the prior art, the utility model has been owing to adopted spiral helicine spiral case separator, when the steam that therefore contains the alkali mist enters, forms the air-flow of strong rotation downwards in the helical duct that can be constituted between spiral case separator and riser; Make the bigger alkali lye of density drop in to be thrown toward under the centrifugal action collector tube tube wall, alkali lye to drip after the condensation to flow down to be pooled to the exit and to discharge that steam is then discharged by riser, thereby realizes that alkali lye separates with steam along tube wall.The utlity model has simple in structure, good separating effect, efficient advantages of higher.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view among Fig. 1;
Fig. 3 is the structural representation of traditional gas-liquid separation device.
Among the figure: riser 1 panel 2 air inlet pipe 3 collector tubes 4 flange sleeves 5 upper cover plates 6 spiral case plates 7 lower covers 8
The specific embodiment:The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Shown in Fig. 1~2: the spiral case separator by the spiral case plate 7 that is curled into the clockwork spring shape, be welded on this spiral case plate top upper cover plate 6, be welded on this spiral case plate bottom lower cover 8, be welded on spiral case plate 7 and upper cover plate 6 and lower cover 8 terminations and have charging hole panel 2, with as described in the charging hole air inlet pipe 3 of fixedly docking constitute, upper cover plate 6 and lower cover 8 are for being cut into spiral helicine flat board.Be welded on the collector tube 4 that is the turbination structure on the lower cover 8 having below the spiral case separator 2, the flange sleeve 5 that is welded on the upper cover plate 6 is being arranged above the described spiral case separator, and the riser 1 of fixedlying connected with this flange sleeve passes spiral case separator 2 and stretches in the collector tube 4; Form a top closure, the uncovered helical duct in bottom between riser 1 and the spiral case separator.
As can be seen from Figure 3,, can only form the more weak eddy current of intensity when steam enters this collector tube 4, so separating effect is obviously not as the utility model owing to do not have helical duct in the collector tube 4.
