Abstract
The utility model discloses a four-into-one high-purity hydrochloric acid graphite synthesis tower, comprising a hydrochloric acid synthesis furnace. A falling film absorbing tower is arranged below the hydrochloric acid synthesis furnace, and the falling film absorbing tower body is provided with a cooling water jacket; the lower part of the falling film absorbing tower is provided with a tail gas aftertreatment tower. The utility model gathers the processes of hydrochloric acid synthesis, absorption, cooling process and tail gas treatment together, which not only can effectively, rapidly and conveniently handle tail gas generated in the synthetic process of hydrochloric acid to increase the yield of products, but also can use semi-product dilute hydrochloric acid produced after tail gas absorption as absorbing liquid for the falling film absorbing tower part so as to enhance product concentration.
Description
The utility model relates to a kind of hydrochloric acid synthesizer.
Traditional hydrochloric acid synthetic furnace has the two-in-one synthetic furnace of carbon steel, the two-in-one synthetic furnace of graphite, the three-in-one synthetic furnace of graphite.The two-in-one synthetic furnace of carbon steel and graphite, chlorine, the synthesizing chlorinated hydrogen of combustion of hydrogen absorb into hydrochloric acid, tail gas HCL, CL with water cooler cooling, resorber then
2Etc. otherwise processed, impurity such as the hydrochloric acid iron content of its production are more, complex process.The three-in-one synthetic furnace of graphite adopts chlorine, combustion of hydrogen to synthesize, and the water absorbing hydrogen chloride also is cooled to hydrochloric acid, tail gas HCL, CL
2Deng separately by independent tail gas again treatment unit handle.
The purpose of this utility model is to provide a kind of and integrates that hydrochloric acid is synthetic, four unification high purity hydrochloric acid graphite synthetic towers of absorption, cooling, vent gas treatment.
Technical solution of the present utility model is:
A kind of four unification high purity hydrochloric acid graphite synthetic towers comprise hydrochloric acid synthetic furnace, and hydrochloric acid synthetic furnace below dress film-falling absorption tower is adorned cooling water jecket on the falling film absorption tower body, and its difference with prior art is: adorn tail gas treating column again in the film-falling absorption tower bottom.
Tail gas has absorption liquid import and rare gas element outlet on the treating column again.Tail gas is treating column bottom dress Explosion-proof cap again.
The utility model integrates that hydrochloric acid is synthetic, absorption, cooling, vent gas treatment, both can make things convenient for efficiently and effectively and handle the tail gas that produces in the hydrochloric acid building-up process, increase the product yield, can utilize the work in-process dilute hydrochloric acid that produces by tail gas absorption back to make the absorption liquid of falling film absorption tower section again, improve product concentration.
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is the configuration diagram of an embodiment of the utility model.
A kind of four unification high purity hydrochloric acid graphite synthetic towers, comprise hydrochloric acid synthetic furnace 1, tool chlorine inlet 13 on the hydrochloric acid synthetic furnace 1, hydrogen inlet 14, hydrochloric acid synthetic furnace 1 below dress film-falling absorption tower 2, have absorption liquid import 3 and finished product hydrochloric acid outlet 8 on the film-falling absorption tower 2, dress cooling water jecket 4 on film-falling absorption tower 2 bodies, tool cooling water inlet 5 and cooling water outlet 6 on the cooling water jecket 4, adorn tail gas treating column 7 again in film-falling absorption tower 2 bottoms, tail gas has absorption liquid import 9 on the treating column 7 again, rare gas element outlet 10, hydrochloric acid export of goods in process of manufacture 11, tail gas is equipped with Explosion-proof cap 12 in treating column 7 bottoms again, and the tail gas internal structure for the treatment of column 7 again is identical with common absorption tower (routine film-falling absorption tower).
In film-falling absorption tower 2 bottoms common gas-liquid separation device is housed, finished product hydrochloric acid is flowed out from the finished product hydrochloric acid outlet, tail gas enters tail gas treating column 7 again, from tail gas again the hydrochloric acid work in-process of the treating column absorption liquid that can be further used as the film-falling absorption tower 2 use, thereby make the finished product salt acid concentration that obtains can reach 31%～35%, purity is also higher.
Claims (3)
1, a kind of four unification high purity hydrochloric acid graphite synthetic towers comprise hydrochloric acid synthetic furnace, and hydrochloric acid synthetic furnace below dress film-falling absorption tower is adorned cooling water jecket on the falling film absorption tower body, it is characterized in that: adorn tail gas treating column again in the film-falling absorption tower bottom.
2, four unification high purity hydrochloric acid graphite synthetic towers according to claim 1, it is characterized in that: tail gas has absorption liquid import and rare gas element outlet on the treating column again.
3, four unification high purity hydrochloric acid graphite synthetic towers according to claim 1 and 2, it is characterized in that: tail gas is treating column bottom dress Explosion-proof cap again.
