Abstract
The utility model discloses a composite tower type efficient separation and purification device. The device comprises a second stage evaporator, a rectification column, a cooling device and an oil-water separation device, wherein the top of the second stage evaporator is in process connection with the rectification column; an oil phase outlet of the oil-water separation device is in process connection with the upper part of the second stage evaporator; the middle section of the second stage evaporator is in process connection with a steam-stripping tower; a steam-stripping medium inlet is formed at the lower part of the steam-stripping tower; and the top of the steam-stripping tower is in process connection with the oil-water separation device by the cooling device. In the composite tower type efficient separation and purification device, the middle section of the second stage evaporator is in process connection with a small steam-stripping tower so as to form a naphthalene separation system; naphthalene is efficiently separated from tar and anthracene oil by processes of steam-stripping, cooling, oil-water separation and cocurrent flowing so as to control the naphthalene content in an anthracene oil product to be less than 1.5 percent; and a naphthalene product with a high added value can be also separated and used. The composite tower type efficient separation and purification device has a simple structure, is convenient to operate, can use low-cost overheated water vapor as the steam-stripping medium, and greatly reduces the production cost.
Description
Technical field
The utility model belongs to the Coal Chemical Industry equipment technical field, is specifically related to a kind ofly be suitable for that coal tar deep processing produces, and can effectively separate naphthalene, improve the compound tower high efficiency separation purifying plant of anthracene oil purity.
Background technology
Along with the CHINESE COAL resource synthetic development utilizes the development of technology, the deep process technology of tar resource is rapidly developed and uses.Naphthalene in the tar is as important chemical material, and its value is the highest, and the good reputation of " the white silver " of tar deep processing industry is arranged.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 primary tar) in tar, the anthracene oil product of the single tower production anthracene oil technology of prior art contains naphthalene all in 5～8% scope, the containing the naphthalene amount and can reach 8～11% of applicant's original product.Some research institution also can only be reduced to 3% with the naphthalene amount that contains of anthracene oil by improving flash evaporator, but the Frame Design of tower needs to transform, cause cost too high, nor can fundamentally improve the purity of anthracene oil and the yield of naphthalene, can't realize the maximized purpose of utilization of resources and interests.For this reason, the design people has developed a kind of compound tower high efficiency separation purifying plant 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 technology is easy, can effectively separate the compound tower high efficiency separation purifying plant of naphthalene, raising tar anthracene oil purity.
The purpose of this utility model is to realize like this, comprise flash evaporator, rectifying tower, refrigerating unit, oily-water seperating equipment, described flash evaporator top is connected with rectifying tower technology, and the oil phase outlet of described oily-water seperating equipment is connected with flash evaporator top technology; Segment process connects the stripping knockout tower in the described flash evaporator, and stripping knockout tower bottom is provided with the stripping medium inlet, and stripping knockout tower top connects oily-water seperating equipment through refrigerating unit technology.
Middle segment process at flash evaporator in the utility model connects small-sized stripping knockout tower, form the naphthalene separation system, by stripping separation, cooling, oily water separation, reflow process, high efficiency separation goes out the naphthalene in the tar anthracene oil, the naphthalene amount that contains of anthracene oil product is controlled at below 1.5%, can also separates, utilize the naphthalene product of high added value.The utility model is simple in structure, and is easy and simple to handle, and can utilizing cheaply, superheated vapour greatly reduces production cost as the stripping medium.
