The absorption system comprises a first-level absorption tower (1), a second-level absorption tower (2), a first-level storing tank (3) and a second-level storing tank (4). A bottom discharging opening of the first-level absorption tower (1) is connected with a charging opening of the first-level storing tank (3), a side discharging opening of the first-level absorption tower (1) is connected with a top charging opening of the second-level absorption tower (2), the bottom discharging opening of the second-level absorption tower (2) is connected with the charging opening of the second-level storing tank (4), the bottom discharging opening of the second-level storing tank (4) is respectively connected with a side charging opening of the second-level absorption tower (2) and the charging opening of the first-level storing tank (3) by a second-level circulating pump (6), and the bottom discharging opening of the first-level storing tank (3) is connected with the side charging opening of the first-level absorption tower (1) by a the first-level circulating pump (5). The hydrogen chloride gas absorption system has the characteristics of high absorption efficiency and less investment in the equipment.
Description
(1) technical field
The utility model relates to a kind of gas absorption system, relates in particular to a kind of hydrogen chloride gas absorption system.Belong to technical field of chemical.
(2) background technology
In the processes such as synthetic pesticide, dyestuff, medicine, a large amount of chlorine-containing compounds all have byproduct hydrogen chloride gas to produce when chemical reaction, and in order to reclaim and administer the pollution that hydrogen chloride causes, general water or alkali lye absorb.The most frequently used absorption equipment is graphite falling film absorbre and filler absorption system at present.
In order to absorb fully, often need what processing of branch.In use have following problem: if adopt the two-stage falling film absorption, then assimilation effect is too poor, does not reach necessary requirement.So generally falling-film absorber and packed tower devices in series are used, but because packed tower is adiabatic absorption process, can cause hydrogen chloride gas basin temperature too high, also can cause assimilation effect not good on the other hand, this just needs the extra heat-exchanger rig that increases, and has increased investment.
(3) summary of the invention
The utility model is to overcome above-mentioned deficiency, and a kind of absorption efficiency height, the little hydrogen chloride gas absorption system of equipment investment are provided.
The purpose of this utility model is achieved in that a kind of hydrogen chloride gas absorption system, it is characterized in that described absorption system comprises first grade absorption tower, two-level absorption tower, one-level basin and secondary basin, discharging opening links to each other with one-level basin charging aperture at the bottom of the described first grade absorption tower, described first grade absorption tower side discharging opening links to each other with two-level absorption tower top charging aperture, discharging opening links to each other with secondary basin charging aperture at the bottom of the described two-level absorption tower, discharging opening links to each other with one-level basin charging aperture with two-level absorption tower side charging aperture respectively by the secondary circulating pump at the bottom of the described secondary basin, and discharging opening links to each other with first grade absorption tower side charging aperture by the one-level circulating pump at the bottom of the described one-level basin.
The utility model hydrogen chloride gas absorption system, described one-level, two-level absorption tower body of the tower comprise upper and lower two parts, and top is falling-film absorber, and the bottom is the packed tower absorber, connects by flange between described falling-film absorber and the packed tower absorber.
The utility model hydrogen chloride gas absorption system has the following advantages:
On the one hand, the hydrogen chloride gas of high temperature plays the effect of cooling after the epimere falling film absorption, heat exchange in time, thus be beneficial to effective absorption of lower end packed tower, reduced the temperature of one-level storage tank simultaneously.
On the other hand, hydrogen chloride gas absorbs repeatedly through falling liquid film section and packing section, makes that absorption is more complete, finally obtains qualified salt acid product.This equipment has not only reduced investment, has more improved absorption efficiency, uses through debugging, and is respond well, produces a desired effect.
(4) description of drawings
Fig. 1 is the utility model hydrogen chloride gas absorption system structural representation.
Among the figure: first grade absorption tower 1,
Two-level absorption tower 2,
One-level basin 3,
One-level circulating pump 5,
Secondary circulating pump 6.
(5) specific embodiment
Referring to Fig. 1, the utility model hydrogen chloride gas absorption system, comprise first grade absorption tower 1, two-level absorption tower 2, one-level basin 3 and secondary basin 4, described first grade absorption tower 1 end discharging opening links to each other with one-level basin 3 charging apertures, described first grade absorption tower 1 side discharging opening links to each other with two-level absorption tower 2 top charging apertures, described two-level absorption tower 2 end discharging opening links to each other with secondary basin 4 charging apertures, described secondary basin 4 end discharging opening links to each other with one-level basin 3 charging apertures with two-level absorption tower 2 side charging apertures respectively by secondary circulating pump 6, and described one-level basin 3 end discharging opening links to each other with first grade absorption tower 1 side charging aperture by one-level circulating pump 5.
Described one-level, two-level absorption tower, its body of the tower comprises upper and lower two parts, and top is falling-film absorber, and the bottom is the packed tower absorber, connects by flange between described falling-film absorber and the packed tower absorber.
During use, the HCl tail gas that top, absorption tower falling-film absorber absorption strength is high makes most of HCl gas be absorbed in this section, and unabsorbed hydrogen chloride gas enters the bottom packing section to be continued to absorb.The hydrochloric acid of making flows out from tower bottom, enter hydrochloric acid tank, unabsorbed hydrogen chloride gas enters secondary absorber again to be continued to absorb, generate hydrochloric acid, enter the hydrochloric acid basin, watery hydrochloric acid in the secondary basin is squeezed into the one-level storage tank again, and circulation absorbs as the one-level absorption liquid, finally obtains qualified salt acid product.
