Abstract
The utility model relates to a combined absorber structure. The combined absorber structure comprises a primary absorbing section and a secondary absorbing section which is arranged above the primary absorbing section, wherein the primary absorbing section and the secondary absorbing section both comprise upper cylinder bodies, middle cylinder bodies and lower cylinder bodies; the combined absorber structure further comprises a graphite pipeline in a vertical direction; the lower end of the graphite pipeline is communicated with a cavity of the lower cylinder body of the primary absorbing section; the upper end of the graphite pipeline is communicated with a cavity of the lower cylinder body of the secondary absorbing section; and the upper end of the graphite pipeline extends from the bottom of the lower cylinder body of the secondary absorbing section to the top of the lower cylinder body of the secondary absorbing section; and the combined absorber structure is characterized in that the upper end of the graphite pipeline is sealed and through holes are uniformly formed in the side surface of the upper end of the graphite pipeline. As the upper end of the graphite pipeline is sealed and the through holes are formed in the side surface of the upper end of the graphite pipeline, absorbed hydrogen chloride gas moves upward along the graphite pipeline at the tail end of the primary absorbing section and is discharged out from the through holes in the side surface; and diluted hydrochloric acid of the secondary absorbing section cannot directly fall into the graphite pipeline from an opening at the upper end of the graphite pipeline during entering the lower cylinder body from a middle cylinder body filler layer; therefore, the absorption rate of the hydrogen chloride is increased.
Description
Technical field
The utility model relates to a kind of Chemical Manufacture and uses gas absorber, particularly a kind of hydrogenchloride unit absorber of good absorbing effect.
Background technology
In the Chemical Manufacture, hydrogen chloride synthetic furnace makes hydrogen chloride gas, and hydrogen chloride gas need absorb through low-concentration hcl or water and make concentrated hydrochloric acid.Low-concentration hcl and hydrogen chloride gas all move from top to bottom in traditional hydrogen chloride absorption device, when mobile, dissolve in the low-concentration hcl after the interchanger cooling heat release of hydrogen chloride gas through the stage casing, thereby make concentrated hydrochloric acid.
A kind of combined absorbing tower has appearred at present, the secondary absorber portion composition that it comprises an absorber portion and is located at an absorber portion top, and the liquid outlet of secondary absorber portion is communicated with the fluid inlet of an absorber portion through by-pass line; The graphite pipeline that also comprises a vertical direction; This graphite lower end of duct is communicated with an absorber portion lower shell inner chamber; Graphite pipeline upper end is communicated with secondary absorber portion lower shell inner chamber, and the upper end of graphite pipeline extends to the top from the bottom of secondary absorber portion lower shell always.Hydrogen chloride gets into from secondary absorber portion top, and gets into the upper shell of an absorber portion through liquid outlet, moves down along vertical run with the hydrogen chloride gas at this place, and the part hydrogen chloride gas is dissolved in the Hydrogen chloride, discharges from an absorber portion bottom then; Undissolved part hydrogen chloride gas rises with the graphite pipeline, gets into the secondary absorber portion, in the packing layer of secondary absorber portion, contacts once more with the Hydrogen chloride that gets into from secondary absorber portion top and carries out secondary and absorb the specific absorption of raising hydrogen chloride gas.
The shortcoming of this kind structure is: because the non-sealing in graphite pipeline top, when Hydrogen chloride descended through the middle cylinder body packing layer, part Hydrogen chloride directly fell into the graphite pipeline, can not absorb through an absorber portion, has reduced assimilation effect.
Summary of the invention
The technical problem that the utility model will solve provides a kind of hydrogenchloride unit absorber of good absorbing effect.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of unit absorber structure; The secondary absorber portion that comprises an absorber portion and be located at absorber portion top is formed, a said absorber portion and secondary absorber portion by last, in three part cylindrical shells composition down; The upper shell sidewall of an absorber portion has fluid inlet, hydrogenchloride import; Middle cylinder body is a graphite heat exchanger; Graphite heat exchanger is provided with the vertical run and the horizontal run of not conducting each other, and horizontal run is communicated with cooling water sandwich, and the vertical run upper end is communicated with the inner chamber of upper shell; The lower shell inner chamber is communicated with the vertical run lower end, and the lower shell bottom has the acid outlet; The upper shell of secondary absorber portion has gas outlet and fluid inlet, and middle cylinder body is filled with packing layer, and the lower shell sidewall has liquid outlet, and the liquid outlet of secondary absorber portion is communicated with the fluid inlet of an absorber portion through pipeline; The graphite pipeline that also comprises a vertical direction; This graphite lower end of duct is communicated with an absorber portion lower shell inner chamber; Graphite pipeline upper end is communicated with secondary absorber portion lower shell inner chamber, and the upper end of graphite pipeline extends to the top from the bottom of secondary absorber portion lower shell always; Its innovative point is: the last end closure of said graphite pipeline, graphite pipeline upper side is evenly distributed with through hole.
The advantage of the utility model is: the upper end sealing of graphite pipeline; In upper side through hole is set; Up along the graphite pipeline at the unabsorbed hydrogen chloride gas of absorber portion, through hole is discharged from the side, and the Hydrogen chloride of secondary absorber portion is when the middle cylinder body packing layer gets into lower shell; Can directly not fall in the graphite pipeline, improve the specific absorption of hydrogen chloride gas from graphite pipeline open upper end.
Description of drawings
Fig. 1 is the utility model unit absorber structural representation.
Embodiment
As shown in Figure 1, tower body is made up of with secondary absorber portion 2 absorber portion 1, and secondary absorber portion 2 is arranged on the upper end of an absorber portion 1.
One time absorber portion divides 1 to be the upper, middle, and lower part cylindrical shell, and upper shell 11 is the graphite cylindrical shell, and upper shell 11 sidewalls have fluid inlet g, hydrogenchloride import e and venting d2; Middle cylinder body is made up of graphite heat exchanger 12 peripheral hardware steel shell 13; Form cooling water sandwich between steel shell 13 and the graphite heat exchanger 12, steel shell 13 tops have cooling water outlet h, and entrance of cooling water k and sewage draining exit j are opened in the bottom; Graphite heat exchanger 12 is provided with vertical run 14 and horizontal run 15; Horizontal run 15 and vertical run 14 not conductings each other, horizontal run 15 is communicated with cooling water sandwich, and vertical run 14 upper ends are communicated with the inner chamber of upper shell 11; Lower shell 16 is the graphite cylindrical shell, and lower shell 16 inner chambers are communicated with vertical run 14 lower ends, and lower shell 16 bottoms have acid outlet b.
Secondary absorber portion 2 is divided into the upper, middle, and lower part cylindrical shell equally, and upper shell 21 is the graphite cylindrical shell, and upper shell 21 tops have gas outlet a, and upper shell 21 side walls have fluid inlet c; Middle cylinder body 22 is the graphite cylindrical shell, establishes the supporting plate 23 that is uniformly distributed with through hole in middle cylinder body 22 bottoms, is filled with packing layer in the middle cylinder body 22 on the supporting plate 23, and middle cylinder body 22 top sidewalls have venting d1; Lower shell 26 is the graphite cylindrical shell, has liquid outlet f at lower shell 26 sidewalls.
