Abstract
The invention relates to a device separating hydrochloride which is mingled with germanium tetrachloride in the production of germanium tetrachloride for optical fibers, and the device belongs to a production device of the germanium tetrachloride for optical fibers. A separating device is mainly composed of a main separation column, a feed pipe, a tail gas discharge pipe, an atmosphere supply pipe, an acid discharge pipe and a discharging pipe. The top of the main separation column is connected with the feed pipe, the lateral part of which is connected with the tail gas discharge pipe, and the upper side of the main separation column is connected with the acid discharge pipe. The intermediate section of the main separation column is connected with the discharging pipe, a pipe orifice of which extends to the bottom of the main separation column, and the feed pipe is connected with the atmosphere supply pipe, the lateral part of which is communicated with the acid discharge pipe and the feed pipe respectively through two independent pipelines. When the device operates, the real-time separation process can be observed, and the hydrochloride and the germanium tetrachloride can be effectively separated. The whole separation process is isolated from air, thereby avoiding the secondary pollution of the product, and the device has the advantages of simple structure, convenience and practicality and high efficiency.
Description
Technical field the present invention relates to a kind of in producing the germanium tetrachloride for optical fibre product, and the device of from germanium tetrachloride hydrochloric acid being separated especially can separate the hydrochloric acid that is mingled with in the germanium tetrachloride completely.Belong to the dedicated separation apparatus field.
Background technology
Germanium tetrachloride for optical fibre is as the important source material of producing optical fiber, has the good market requirement, present most of germanium tetrachloride for optical fibre mainly relies on external import, and the technology of preparing of germanium tetrachloride for optical fibre is monopolized by external always, and China is implemented blockade on new techniques.
Adopting classical chlorination process to produce needs in the germanium tetrachloride process to use hydrochloric acid as raw material, but the germanium tetrachloride for optical fibre product has strict requirement to its content.Therefore, in producing the germanium tetrachloride for optical fibre process, need the hydrochloric acid that is entrained in is wherein effectively separated, to guarantee the quality of product.
Summary of the invention the object of the invention is to provide a kind of and in producing the germanium tetrachloride for optical fibre process hydrochloric acid that is mingled with is carried out effective isolating tripping device.This device adopts quartz material, has very strong erosion resistance, and Clear ﹠ Transparent, can see the tripping device of sepn process in real time.Whole tripping device is inner for can form a controllable gas atmosphere, allows complete and air insulated in the sepn process, avoids the secondary pollution of product.
The apparatus structure that the present invention separates hydrochloric acid in the germanium tetrachloride for optical fibre is:
Tripping device is by main knockout tower, feed-pipe, tail gas discharging pipe, atmosphere supply pipe, ACID and discharge nozzle are formed, be connected to a feed-pipe (1) on the top of main knockout tower (6), feed-pipe (1) sidepiece is connected to tail gas discharging pipe (2), main knockout tower (6) upper lateral part is connected to ACID (4), main knockout tower (6) stage casing is connected to a discharge nozzle (5), discharge nozzle (5) mouth of pipe reaches main knockout tower (6) bottom, be connected to atmosphere supply pipe (3) on the discharge nozzle (5), atmosphere supply pipe (3) sidepiece is respectively separately by two independently pipeline and ACID (4) and feed-pipe (1) connections.
The whole tripping device of the present invention is a hyalosome, all adopts quartz material.
Principle of work: hydrochloric acid and germanium tetrachloride all have very strong corrodibility, so the whole tripping device of the present invention all adopts quartz material.Tripping device has very strong erosion resistance, and Clear ﹠ Transparent, can the Real Time Observation separation case.
After mixture was put into main knockout tower (6), the proportion of hydrochloric acid was lower than germanium tetrachloride, the two easy layering, and hydrochloric acid floats on the top of germanium tetrachloride, and realization hydrochloric acid effectively separates with germanium tetrachloride.According to the needs of manufacturing condition, in whole sepn process, the atmosphere of whole tripping device internal gas is controlled, allow whole tripping device inside and air insulated, avoid the secondary pollution of product.
For ease of atmosphere control, on tripping device, reserve the atmosphere feeding channel, according to the process control needs, by gas supply pipe (3) make-up gas, to guarantee the internal atmosphere of tripping device.
Apparatus of the present invention have realized in producing the germanium tetrachloride for optical fibre process hydrochloric acid that is entrained in the germanium tetrachloride effectively being separated, thereby guarantee the quality of germanium tetrachloride product.The hydrochloric acid that especially can effectively separate in the germanium tetrachloride to be mingled with, the production of germanium tetrachloride for optical fibre purified has quite crucial effect.
Beneficial effect of the present invention is: can effectively realize separating of hydrochloric acid and germanium tetrachloride, and can the Real Time Observation sepn process, in the whole sepn process fully and air insulated, avoided the secondary pollution of product, it is simple in structure, and is convenient and practical, the separation efficiency height.
Description of drawings further describes its embodiment below in conjunction with accompanying drawing of the present invention.
Fig. 1 is the structural representation of tripping device of the present invention.
Among the figure: 1. feed-pipe, 2. tail gas discharging pipe, 3. atmosphere supply pipe, 4. ACID, 5. discharge nozzle; 6. main knockout tower.
Embodiment
Embodiment: tripping device is made of main knockout tower (6), feed-pipe (1), tail gas discharging pipe (2), atmosphere supply pipe 3, ACID 4 and discharge nozzle 5, the top of its main knockout tower 6 is connected to a feed-pipe 1, feed-pipe 1 sidepiece is connected to tail gas discharging pipe 2, main knockout tower 6 upper lateral parts are connected to ACID 4, main knockout tower 6 stage casings are connected to a discharge nozzle 5, discharge nozzle 5 mouths of pipe reach main knockout tower 6 bottoms, be connected to atmosphere supply pipe 3 on the discharge nozzle 5, atmosphere supply pipe 3 sidepieces are respectively separately by two independently pipeline and ACID 4 and feed-pipe 1 connections.
Whole tripping device is a hyalosome, all adopts quartz material, has very strong erosion resistance, and Clear ﹠ Transparent, can the Real Time Observation sepn process.
During use, after distillation, be mingled with the feed-pipe 1 that the germanium tetrachloride mixture of a certain amount of hydrochloric acid passes through and enter into main knockout tower 6 inside, because both proportions differences have realized both effective separation.The hydrochloric acid on upper strata is got rid of from ACID 4, and the germanium tetrachloride of bottom is got rid of from discharge port 5; The tail gas that produces in the sepn process can be drained by tail gas discharging pipe 2, and the pressure in the whole tripping device keeps even and guarantees safety.
Sepn process is all the time under the protection of inertia controlled atmosphere, and whole tripping device seals and and air insulated fully.According to the processing condition needs, can control the supply of rare gas element by gas supply pipe (3), cause the secondary pollution of product to avoid entering of air in the sepn process.
The present invention is used for the independent research germanium tetrachloride for optical fibre, breaks external blockade on new techniques to Chinese germanium tetrachloride for optical fibre product.
