Description
Technical field
The utility model is related to a kind of production hydrogen chloride gas device, particularly a kind of hydrogen chloride gas knot screen.
Background technology
Concentrated acid hydrolysis have become the major way of dimethyldichlorosilane hydrolysis.The hydrogen chloride gas produced in Concentrated acid hydrolysis
Body, will be fed into chloromethanes workshop.But as hydrogen chloride gas tolerance is larger, a part of water can be carried secretly and chlorine is entered with siloxanes mist
Methane workshop, to chloromethanes workshop, normally production causes large effect for this.So organosilicon industry can all take some measures
To purify hydrogen chloride gas.
Mist formation mechenism is divided into two kinds by Fabian etc.：Mechanism and steam condensation.Siloxanes mist in this technique
To be produced by mechanism, and mechanism produce mist diameter all more than 5 μm, this is the theoretical foundation of the present invention.
At present, the measure for generally adopting in industry is cooling method or absorption method.Cooling method is to produce hydrolyzing dimethyl dichlorosilane
Hydrogen chloride gas are passed through multistage cooler, by Physical temperature-lowering, the water that carries secretly in hydrogen chloride gas, siloxanes mist etc. are cooled down
It is gathered into larger drop, larger drop flows to cooler bottom due to the effect of gravity, so as to the water in de-chlorine hydride
With siloxanes；And absorption method is that hydrogen chloride gas are passed through deentrainment tower, when the gas with mist is risen through with certain speed
During silk screen, due to the effect of inertia that mist rises, mist collides and is attached in filament surfaces with wire mesh filaments.Filament table
The gravitational settling of mist on face, makes mist form the interface point that larger drop flow to two silks along filament.The surface of liquid
Tension force and the capillarity of filament so that drop is increasing, until assemble drop reach a certain size after, drop just from
Separate on filament.Both the above mode can all purify hydrogen chloride gas.But cooling method degree of purification is poor；Though and absorption method
The impurity such as siloxanes in hydrogen chloride gas body can be preferably removed, but as tolerance is larger, demisting tower packing can be caused larger
Load, need often filler is cleared up and is changed, have a strong impact on the normal production in workshop.Therefore, it is badly in need of a kind of new
Method, in the case of production is not affected, effectively remove the siloxanes in hydrogen chloride gas body.
Utility model content
Goal of the invention of the present utility model is to provide a kind of hydrogen chloride knot screen for improving hydrogen chloride gas purity.
The utility model is adopted the following technical scheme that：
A kind of hydrogen chloride knot screen, including hydrolysis reactor, condenser, hydrolysis reactor are connected with condenser, condensation
Device is connected with cyclone separator, and cyclone separator is connected with deentrainment tower, and deentrainment tower is connected with chloromethanes operation.
The utility model compared with prior art, ensure that the purity of output hydrogen chloride gas, reduces and is covered using single
Load during separator, extends the service life of equipment.
The utility model adopt preferred version be：
Condenser is set to two-stage：First-stage condenser and secondary condenser.
Deentrainment tower is divided into one-level deentrainment tower and two grades of deentrainment towers.
Cooling medium in condenser is -15 DEG C of ethylene glycol.
Condenser, cyclone separator and deentrainment tower are connected with preseparator respectively.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment describes the utility model in detail：
In Fig. 1：Hydrolysis reactor 1, first-stage condenser 2, secondary condenser 3, cyclone separator 4, one-level deentrainment tower 5, two
Level deentrainment tower 6, preseparator 7, chloromethanes workshop 8.
In the present embodiment, hydrolysis reactor 1 is connected with first-stage condenser 2, and first-stage condenser 2 is connected with secondary condenser 3,
Secondary condenser 3 is connected with cyclone separator 4, and cyclone separator 4 is connected with one-level deentrainment tower 5, and one-level deentrainment tower 5 is removed with two grades
Mist tower 6 is connected with the production process in chloromethanes workshop 8.
Cooling medium in first-stage condenser 2 and secondary condenser 3 is respectively -15 DEG C of ethylene glycol.
First-stage condenser 2, secondary condenser 3, cyclone separator 4,5, two grades of deentrainment towers 6 of one-level deentrainment tower are divided with pre- respectively
Connect from device 7.
The hydrogen chloride gas produced by hydrolysis reactor 1 sequentially enter first-stage condenser 2, secondary condenser 3, cooler
Cooling medium is -15 DEG C of ethylene glycol, and the hydrogen chloride gas temperature after B-grade condensation reaches -10 DEG C.
After condensed, whole water of hydrogen chloride gas entrained with and it is relatively large in diameter（It is the diameter about 10 of less mist
More than times）Droplets of siloxane will gather condenser bottom, enter in preseparator 7 with pipeline.Less siloxanes mist
Foam（10um～100um）As hydrogen chloride gas enter cyclone separator 4 with the speed of 10m/s, cyclone separator 4 is by machinery
Motion, produces centrifugal force, liquid larger for density is thrown on outer wall from hydrogen chloride gas, and the liquid on outer wall is due to gravity
Effect, flows in liquid below collection device.Cyclone separator 4 separates the diameter of liquid in 5 more than μ, according to the shape of mist
Become mechanism to understand, most siloxanes will be removed.Hydrogen chloride gas afterwards again pass by the one-level of 2 μ of separation accuracy and remove
Mist tower 5 and two grades of deentrainment towers 6, are delivered to chloromethanes workshop 8 after evolving again.
Condenser isolates whole water and macromolecular siloxanes；Most siloxanes isolated by cyclone separator 4, with
Shi Youxiao reduces deentrainment tower load, it is ensured that purifier being capable of stable operation；Obtain after being purified through deentrainment tower again pure
Hydrogen chloride gas.This device is installed successively according to separating power, and the hydrogen chloride gas containing liquid foam are obtained pure through multistage purification
Hydrogen chloride gas；Meanwhile, the siloxanes that isolates enters preseparator, recycling.
The utility model ensure that the purity of hydrogen chloride gas, reduce chloromethanes workshop because of the maintenance produced by equipment blocking
Expense；Reduce the load of one-level deentrainment tower 5 and two grades of deentrainment towers 6, extend the service life of equipment；Reduce the shadow to producing
Ring.
