Description

A kind of device preparing Methyl Hydrogen Polysiloxane Fluid

Technical field

This utility model relates to a kind of device preparing Methyl Hydrogen Polysiloxane Fluid。

Background technology

Mostly adopting azeotropic acid hydrolysis process in industrialized production Methyl Hydrogen Polysiloxane Fluid, azeotropic acid hydrolysis device includes a graphite condenser, a circulating pump and many grade hydrochloric acids subsider, process route is long, equipment is complicated, and graphite condenser needs to lower the temperature with chilled brine, and energy consumption is high。

Summary of the invention

The purpose of this utility model aims to provide a kind of device preparing Methyl Hydrogen Polysiloxane Fluid, overcomes the deficiencies in the prior art, is substantially reduced energy consumption, improves production efficiency, reduces production cost。

For achieving the above object, the device preparing Methyl Hydrogen Polysiloxane Fluid of the present utility model includes tower reactor, tower reactor top arranges HCl escape orifice, HCl escape orifice pipeline arranges piezometer, on tower reactor, waist arranges hydrolysate overfall, arranging thermometer on hydrolysate overfall pipeline, under tower reactor, waist arranges water supplement port, arranges material inlet bottom tower reactor。

Saturated acid hydrolysis device, is the tower reactor of continuous prodution Methyl Hydrogen Polysiloxane Fluid, and reactor material selects enamel or steel lining politef。

During use, first this reactor inner chamber is put into saturated hydrochloric acid, the mixture of methyl hydrogen dichlorosilane and trim,ethylchlorosilane enters from the bottom of reactor, with the water generation hydrolysis in saturated hydrochloric acid, in course of reaction, the HCl gas of effusion enters device for absorbing tail gas by top HCl escape orifice and makes the hydrochloric acid of 31%, the moisture that course of reaction consumes is supplemented by water supplement port, after reaction the hydrolysate arrived due to the density contrast between saturated hydrochloric acid, float up to overfall and enter next process, owing to HCl overflows in gaseous form, it is not dissolved in reactor, this course of reaction does not produce heat, and the density of saturated hydrochloric acid and reaction hydrolysate density contrast are from bigger, reaction hydrolysate is more thorough with the layering of hydrochloric acid, in hydrochloric acid, oil-in-water phenomenon is solved, improve product yield, reach the effect of energy-saving consumption-reducing。

The device preparing Methyl Hydrogen Polysiloxane Fluid of the present utility model compared with prior art has following excellent effect。

Adopt the device preparing Methyl Hydrogen Polysiloxane Fluid of the present utility model, the feature of silane chloride hydrolysis can be made full use of, hydrolytic process not heat release, but hydrolysis produces HCl gas is dissolved in the water substantial amounts of heat of releasing, this reactor is utilized to prepare Methyl Hydrogen Polysiloxane Fluid, the HCl gas that hydrolysis produces can not be dissolved in reactor, do not produce heat, and utilize saturated hydrochloric acid and reactant density contrast to widen, it is layered more thorough, improve product yield, reach the effect of energy-saving consumption-reducing, 31% hydrochloric acid can be effectively made in hydrogen chloride effusion, it is easy to by-product hydrochloric acid sell, it is substantially reduced energy consumption, improve production efficiency, reduce production cost。

Accompanying drawing explanation

Fig. 1 is the overall schematic of the device preparing Methyl Hydrogen Polysiloxane Fluid of the present utility model。

Wherein: 1, for tower reactor, 2, for HCl escape orifice, 3, for hydrolysate overfall, 4, for water supplement port, 5, for material inlet, 6, for piezometer, 7, for thermometer。
