According to the innovation point, a secondary distribution unit for converging and distributing descending liquid in the tower body is arranged between the adjacent packing sections; the descending liquid enters the tower body from the liquid inlet pipe, is dispersed downwards to enter the packing sections under the action of liquid inlet distributors and is in contact with gaseous phases which ascend in the reverse direction in the packing sections; low-boiling point components in the descending liquid are transferred to the gaseous phases continuously; and after passing through the packing sections, the descending liquid descends continuously to enter the secondary distribution units, slides downwards under the action of a corresponding liquid collecting plate at each position to enter annular liquid collecting tanks along horizontal liquid collecting channels, is converged in the annular liquid collecting tanks and subjected to heat balance, and is distributed by distributors and enters the next layer of packing section to be in contact with and separated from the gaseous phases, so that the descending liquid is in contact with the gaseous phases fully, energy is distributed uniformly, and a rectifying effect is improved.
Description
Technical field
The utility model relates to a kind of rectifying column, particularly a kind of graphite rectifying column.
Background technology
Rectifying column is a kind of tower vapor-liquid contacting apparatus that carries out rectifying, is called destilling tower again.As inner barrel, it has advantages such as highly corrosion resistant and high-termal conductivity to the graphite rectifying column with graphite material.Its operation principle does, steam gets at the bottom of by tower, evaporates the gas phase and the decline liquid that and carries out counter current contacting; Two contact, and volatile (low boiling) component in the decline liquid constantly shifts in gas phase, and difficulty volatilization (higher boiling) component in the gas phase constantly shifts in decline liquid; Gas phase is more near cat head, and its volatile components concentration is higher, and decline liquid is more near at the bottom of the tower; Its difficult volatile component is more enrichment then, thereby reaches the purpose that component is separated.
Tradition rectifying column structure is: some distribution cards are set in tower body from top to bottom, between the distribution card, packing layer are set.The shortcoming of this kind structure is: decline liquid in the decline process, though through after packing layer and the distribution that distributes card with the gas phase even contact because various uncertain factors cause local flow, the uneven problem of heat distribution, influence rectification effect.
Summary of the invention
The technical problem that the utility model will solve provides a kind of decline liquid distributed uniform, the good graphite rectifying column of rectification effect.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of graphite rectifying column; Comprise tower body, said tower body top is provided with feed tube, and the middle part is provided with the several layers packing section; The bottom is provided with drain pipe and steam inlet, and its innovative point is: be provided with the secondary distribution unit that decline liquid in the tower body is compiled reallocation between the said adjacent packing section.
Further, said secondary distribution unit comprises liquid collecting plate group, collecting tank, downspout and the distributor that is provided with from top to bottom; Said liquid collecting plate group is made up of the liquid collecting plate that several are arranged in parallel, and the outlet end of said each liquid collecting plate is communicated with collecting tank, and said collecting tank is communicated with the liquid feeding end of downspout, and said distributor is positioned at the outlet end below of downspout.
Further, said liquid collecting plate comprises the swash plate of an inclination, in the swash plate bottom baffle plate is set, and forms a horizontal liquid collecting passage between said baffle plate and the swash plate.
Further, said collecting tank is the loop configuration that a circle is provided with along the tower body inwall.
Further, said downspout comprises the vertical pipe that a horizontal pipe and a upper end are communicated with the horizontal pipe middle part, and the two ends of horizontal pipe are and the liquid feeding end of collecting tank conducting that the lower end of vertical pipe is an outlet end.
Further, said distributor is a trench structure, is distributed with through hole in the bottom of distributor.
Further, the sidewall of said distributor has through hole.
Further, the sidewall upper edge of said distributor is provided with the zigzag overflow launder.
The advantage of the utility model is: decline liquid gets in the tower body through feed tube; Under the effect of feed liquor distributor, disperse to get into packing section downwards; In packing section, contact, the low boiling component in the decline liquid is constantly shifted in gas phase with the gas phase of reverse rising; Decline liquid is descending through the packing section continued, gets into the secondary distribution unit, and under the effect of the corresponding liquid collecting plate in each position, gliding also gets into annular collecting tank along horizontal liquid collecting passage; In annular collecting tank, compile; And carry out heat balance, distributing once more through distributor then gets into the packing section and the gas phase contact separation of one deck down, makes decline liquid fully contact with gas phase; Energy distribution is even, improves rectification effect.

The specific embodiment
As shown in Figure 1, comprise tower body 1, feed tube 2, packing layer 3, distribute card 4, drain pipe 5, secondary distribution unit 6.
Above-mentioned tower body 1 top is provided with feed tube 2, and the middle part is provided with the several layers packing section, and packing section is made up of the distribution card 4 of packing layer 3 and upper and lower thereof, and the bottom is provided with drain pipe 5 and steam inlet.
Between adjacent packing section, be provided with secondary distribution unit 6, as shown in Figure 2, this secondary distribution unit comprises liquid collecting plate group, collecting tank 8, downspout 9 and the distributor 10 that is provided with from top to bottom.The liquid collecting plate group is made up of several liquid collecting plates 7 that are arranged in parallel, and the outlet end of each liquid collecting plate 7 is communicated with collecting tank 8, and collecting tank 8 is communicated with the liquid feeding end of downspout 9, and distributor 10 is positioned at the outlet end below of downspout 9.
The concrete structure of secondary distribution unit 6 each assembly is:
Liquid collecting plate 7 is as shown in Figure 3, specifically comprises the swash plate 71 of an inclination, in swash plate 71 bottoms baffle plate 72 is set, thereby constitutes the horizontal liquid collecting passage of one " √ " shape.The angle of inclination of swash plate 71 is 60 °, and the angle of inclination of baffle plate 72 is 120 °.
