Abstract
The utility model discloses a small efficient steam-stripping separating device, which comprises a tower body (6), a feed distributor, a steam distributor (1) and a separating element (2), wherein the steam distributor (1) is arranged at the bottom of the tower body (6), the separating element (2) is arranged at the middle part of the tower body (6), the feed distributor is arranged above the separating element (2), the feed distributor is communicated with a liquid-phase feeding pipe (5), and a gas-phase outlet (4) is arranged at the top of the tower body (6). The utility model effectively decreases the diameter and the height of the tower body by adopting the efficient separating element, greatly lowers the operating weight, satisfies the bearing requirement of an original frame when in technological transformation, greatly improves the separating efficiency by introducing overheated steam into a tower bottom for steam stripping, is used for separating and extracting the naphthalene in dianthracene oil, can reduce the naphthalene content to be below 1.5 percent, not only realizes the purification of the dianthracene oil, but also effectively separates and extracts the naphthalene with a high added value and has remarkable economic benefit and wide popularization value.
Description
Technical field
The utility model belongs to chemical production technical field, is specifically related to a kind of being particularly useful for to separate high value added product from the anthracene oil of coal tar processing---the small-sized efficient stripping separator of naphthalene.
Background technology
Utilize the development of technology with the CHINESE COAL resource synthetic development, the deep process technology of tar resource is rapidly developed and uses.Wherein naphthalene is as important chemical material in the tar, and its value is the highest, is the white silver of tar deep processing industry, and the yield that how to improve naphthalene is one of target of tar deep processing industry pursuit always.Anthracene oil accounts for 6～8% (also have and reach 12% high crude tar) in tar, in an existing the most general tower technological process of production, its anthracene oil contains naphthalene all in 5～8% scope, applicant's product once reached 8～11%, many research institutions and designing unit try hard to effectively anthracene oil to be contained naphthalene in the design flash evaporator and are reduced to 3%, cause bigger transformation, bring series transformations such as general frame design the flash evaporator main equipment.Thereby many enterprises can't realize reducing anthracene oil and contain the naphthalene amount, improve the yield of naphthalene, realize the optimum utilization of enterprise profit maximization and resource.Therefore carry out and reduce anthracene oil to contain naphthalene be the practical significance that has very much reality.For this reason, the design people has developed a kind of small-sized efficient stripping separator through comprehensive test study, evidence, and effect is good.
The utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, and process stabilizing especially is adapted to separate the small-sized efficient stripping separator of high added value naphthalene in the anthracene oil.
The purpose of this utility model is to realize like this, comprise tower body, feed distributor, steam distributor, resolution element, the tower body bottom is provided with steam distributor, the tower body middle part is provided with resolution element, the resolution element top is installed and is put feed distributor, feed distributor is by being communicated with feed pipe, and the tower body top is provided with gaseous phase outlet.
The utility model adopts efficient resolution element, effectively reduced the diameter and the height of tower body, Operating Weight has been descended greatly, the requirement of former framework load-bearing when satisfying technological transformation, feed the superheated steam stripping at the bottom of the tower, separative efficiency greatly improves, and is used for the separation and Extraction of anthracene oil naphthalene, can make to contain the naphthalene amount and be reduced to below 1.5%, both realized the purifying of anthracene oil, again effectively separation and Extraction the naphthalene of high added value, remarkable in economical benefits has promotional value widely.
Description of drawings
Fig. 1 is the utility model overall structure cross-sectional schematic;
Fig. 2 is the structural representation of the steam distributor of the utility model use.
Among the figure: 1-steam distributor, 2-resolution element, 3-mist eliminator, 4-gaseous phase outlet, 5-liquid phase feeding pipe, 6-tower body.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is illustrated, but never in any form the utility model is limited, according to training centre of the present utility model do any change or replacement, all belong to protection domain of the present utility model.
As shown in Figure 1, the utility model comprises tower body 6, feed distributor, steam distributor 1, resolution element 2, tower body 6 bottoms are provided with steam distributor 1, the tower body middle part is provided with resolution element 2, resolution element 2 tops are installed and are put feed distributor, feed distributor is by being communicated with liquid phase feeding pipe 5, and tower body 6 tops are provided with gaseous phase outlet 4.
Described resolution element 2 is efficient separating filler or tower tray.
Described efficient separating filler is a kind of in wavy metal filler, metal or ceramic Pall ring filler, metal or ceramic raschig rings filler, plastic flower ring filler or the metal structured packing and more than one combination; Described tower tray is a kind of in sieve plate, bubble-cap, float valve, arc column plate or the slant-hole tray and more than one combination.Can satisfy the purpose that other fillers of separation requirement or tower tray equally can utility models.
The corrugated plating plate number of described wavy metal filler is the 4-8 plate.
Described gaseous phase outlet 4 exits are provided with mist eliminator 3, to reduce the entrained liquid of anthracene oil in the gas phase significantly, with being back in the filled column after the anthracene oil liquid gathering of carrying secretly in the gas phase, guarantee not entrained liquids of gaseous phase outlet 4, satisfy the equally distributed requirement of liquid phase.
Described gaseous phase outlet 4 bottoms are provided with mist eliminator 3.
Fig. 2 shows the structure of steam distributor, and it helps steam and distribute the raising Srteam Stripping effect in filled column.
The operation principle of the present utility model and the course of work:
Hot anthracene oil enters the feed distributor on tower body top by the liquid phase feeding pipe, the power of relying on for support flows from top to bottom, wetting filler, and with superheated steam counter current contacting from tower body bottom steam distributor 1, liquid phase realizes conducting heat at the wetting surface of filler because of drop and the gas phase that self surface tension forms, mass transfer, micro-naphthalene in the anthracene oil is deviate to enter gas phase, contain the naphthalene amount and in the packing layer gaseous component, from bottom to top increase progressively distribution, the naphthalene amount that contains in the descending on the contrary anthracene oil from top to bottom reduces gradually, thereby the efficiently concentrating of realizing micro-naphthalene separates, while purification anthracene oil, making wherein, naphthalene content is reduced to below 1.5%.
The utlity model has the tower body diameter, height dimension is little, the separative efficiency height, simple process is stable, characteristics easy to implement are particularly useful for the technological transformation of existing equipment.
