Abstract
The utility model provides an improve silicon tetrachloride rectifier unit of structure, including the rectifying column, the bottom of rectifying column is provided with at the bottom of reboiler, the tower backflow pipeline at the bottom of ejection of compact pipeline and the tower, and ejection of compact pipeline is linked together through backflow pipeline at the bottom of reboiler and the tower at the bottom of the tower, be provided with the equidistant filter of from the top down in the rectifying column, the one side at rectifying column top is provided with charge -in pipeline, and the opposite side is provided with top of the tower ejection of compact pipeline. Add the ascending silicon tetrachloride steam of thermosetting through carrying the reboiler that heats up in a steamer at the bottom of the tata, carry out mass transfer heat transfer after -separating with silicon tetrachloride material liquid on the filter, the enrichment at the bottom of the tower of difficult volatile silicon tetrachloride hydrolysate, discharge gate extraction at the bottom of the follow tower, and rise to tower end discharge gate on net silicon tetrachloride fraction and distil off, become the liquid phase through the condenser condensation, get into the follow -up in -process of preparation white carbon preparation, thereby the influence of silicon tetrachloride hydrolysate such as silicic acid to the follow -up operation of white carbon preparation has been avoided.
Description
Technical field
The utility model relates to a kind of silicon tetrachloride rectifier unit of modified node method.
Background technology
Silicon tetrachloride is water white fuming liquids, and facile hydrolysis in humid air also produces the hydrolysates such as silicic acid gel.When taking silicon tetrachloride as raw material production white carbon, hydrolysate such as the silicic acid etc. of silicon tetrachloride also can exist in raw material simultaneously, when taking silicon tetrachloride as raw material production gas-phase silica, the hydrolysates such as the silicic acid in raw material are the plug nozzle in the place's fouling of feed arrangement nozzle easily, and preparation manipulation cannot normally be carried out.Therefore, the hydrolysate existed in removing silicon tetrachloride, to eliminate because the blocking at nozzle place is on the impact preparing white carbon, becomes urgent problem in white carbon preparation facilities.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, provides a kind of silicon tetrachloride rectifier unit effectively removing hydrolyzing silicon tetrachloride product.
To achieve the above object, the utility model have employed following technical scheme:
There is provided a kind of silicon tetrachloride rectifier unit of modified node method, comprise rectifying column, the bottom of described rectifying column is provided with reflux line at the bottom of discharge pipe at the bottom of reboiler, tower and tower, and discharge pipe at the bottom of tower is connected with reflux line at the bottom of tower by reboiler; Be provided with equally spaced filter from top to bottom in described rectifying column, the side at described rectifying column top is provided with feed pipe, and opposite side is provided with tower top discharge pipe, and described tower top discharge pipe is sealedly connected with condenser; Described condenser is connected with storage tank by pipeline, and storage tank is provided with output channel and reflux line, and storage tank is connected with rectifying column top by reflux line.Thermosetting rising silicon tetrachloride vapor is added by carrying the reboiler heated up in a steamer at the bottom of tower tower, filter carry out after mass-and heat-transfer is separated with silicon tetrachloride feed liquid, hydrolyzing silicon tetrachloride product enrichment at the bottom of tower of difficult volatilization, discharging opening extraction at the bottom of tower, and pure silicon tetrachloride cut rises to tower end discharging opening distillates, liquid phase is become through condenser condenses, enter and prepare in subsequent process prepared by white carbon, thus avoid the hydrolyzing silicon tetrachloride products such as silicic acid prepare subsequent operation impact on white carbon, solve the problem of the easy fouling in nozzle place, high purity silicon tetrachloride effecting reaction is made to generate white carbon, thus improve quality of white carbon black product.
As preferably, described filter is evenly covered with the sieve plate having aperture 25mm ~ 30mm circular hole, both hydrolyzing silicon tetrachloride product had been prevented to block sieve aperture, avoid again crossing ambassador's moisture hydrolysis products silicon tetrachloride material because of aperture directly to flow down from sieve aperture, thus ensure that upflowing vapor and descending liquid fully carry out mass-and heat-transfer on filter.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Accompanying drawing illustrates: feed pipe 1, filter 2, condenser 3, tower top discharge pipe 31, storage tank 4, output channel 41, reflux line 42, rectifying column 5, reboiler 6, reflux line 61 at the bottom of tower, discharge pipe 62 at the bottom of tower.
Detailed description of the invention
