The technical problem that the utility model solved realizes by the following technical solutions:
A kind of anhydrous hydrofluoric acid rectifying column, comprise air rising hole, jet cover, the jet cover top board, column plate, downspout, deflector apron, downflow weir, tower body, the skylight, leg, spray-hole and pilot hole, described jet cover top board is positioned at the upper end of jet cover, described jet cover lower limb evenly is connected with 3-4 leg, described jet cover is in the position of the rise hole of column plate, leave fluid course between the bottom surface of described jet cover and the column plate, be evenly distributed with spray-hole on the described jet cover, evenly have pilot hole on the described jet cover top board, described jet cover is cylindrical or truncated cone-shaped, described jet cover top board be shaped as circle with jet cover coupling, have the skylight between described jet cover and the jet cover top board, horizontal column plate of several layers and supporting with it downspout and downflow weir are installed in the described tower body, have the plurality of rows air rising hole vertical on the described column plate with the liquid phase flow direction, on the position corresponding, jet cover is installed, and every row's jet cover is adopted as the alternate mounting means of arranging straggly of height with air rising hole.
Beneficial effect
It is big to the utlity model has disposal ability, mass-transfer efficiency height, advantage such as pressure drop is little, and operating flexibility is big.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model;
Fig. 2 is the vertical view of jet cover of the present utility model;
Fig. 3 is the front view of jet cover of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, Fig. 2, Fig. 3, a kind of schematic diagram of anhydrous hydrofluoric acid rectifying column, a kind of vertical view of jet cover of anhydrous hydrofluoric acid rectifying column, a kind of front view of jet cover of anhydrous hydrofluoric acid rectifying column, a kind of anhydrous hydrofluoric acid rectifying column, comprise air rising hole 1, jet cover 2, jet cover top board 3, column plate 4, downspout 6, deflector apron 7, downflow weir 9, tower body 10, skylight 11, leg 12, spray-hole 13 and pilot hole 14, described jet cover top board 3 is positioned at the upper end of jet cover 2, described jet cover 2 lower limbs evenly are connected with 3-4 leg 12, described jet cover 2 is in the position of the rise hole 1 of column plate 4, leave fluid course between the bottom surface of described jet cover 2 and the column plate 4, be evenly distributed with spray-hole 13 on the described jet cover 2, evenly have pilot hole 14 on the described jet cover top board 3, described jet cover 2 is cylindrical or truncated cone-shaped, described jet cover top board 3 be shaped as circle with jet cover 2 coupling, have skylight 11 between described jet cover 2 and the jet cover top board 3, horizontal column plate 4 of several layers and supporting with it downspout 6 and downflow weir 9 are installed in the described tower body 10, have on every layer of column plate 4 with liquid and flow the vertical plurality of rows air rising hole 1 of 8 directions, on the position corresponding, jet cover 2 is installed, and every row's jet cover 2 is adopted as the alternate mounting means of arranging straggly of height with air rising hole 1.
During operation, liquid phase 8 flows into this layer column plate 4 from the downspout 6 of last layer column plate 4, every row's jet cover 2 of flowing through flows to down on one deck column plate 4 through downspout 6 again, gas phase 5 enters in the jet cover 2 of this layer column plate 4 from the below of column plate 4 by air rising hole 1, in gas phase 5 enters jet cover 2 and when rising, liquid phase 8 enters from the fluid course of the bottom surface of jet cover 2, gas-liquid two-phase carries out violent mixing contact in jet cover 2, liquid phase 8 is broken into the drop that varies in size in a large number by gas phase 5 in contact process, after this gas-liquid mixture is spouting from the pilot hole 14 of the sidewall spray-hole 13 of jet cover 2 and bar shaped skylight 11 and jet cover top board 3, at first beat on described guiding plate washer 7 by the gas-liquid mixture that eject in skylight 11, the gas-liquid mixture that is ejected by the pilot hole on the jet cover top board 3 14 can be stopped because of the fish scale shape of pilot hole 14, in this process, drop continues to be broken, after the mixing, opening direction along deflector apron 7 or fish scale pilot hole 14 is spouting, last gas phase 5 and the drop place, space between jet cover 2 and column plate 4 is through the collision cohesion, drop captures, processes such as jet cover top board 3 captures and gas phase 5 are in the curve baffling rising centrifugation of 2 of jet covers, drop can fall back in the liquid phase 8 on the column plate 4 and flow to down on one deck column plate 4 by downspout 6 subsequently, and gas-liquid two-phase is finished mass transfer in this contact process, processes such as heat transfer.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model; the technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
