Description

Hydrolysis reactor

Technical field

The invention relates to a kind of reactor, relates to a kind of novel high-tech material---organosilyl hydrolysis reactor that is used to produce particularly.

Background technology

Organosilicon product unique properties, superior, the progress of production technology have been developed its potential in fields such as building, electronics, automobile, health products, more and more are applied to people's life.

At present, the market share of organosilicon 80% is controlled in the external manufacturer hand, and Chinese organosilicon industry still is in the growth stage.The existing equipment that domestic each organosilicon production firm adopts in use just mixes before organic matter and sour water enter reactor, causes the reaction of organic matter and sour water insufficient, makes the output of hydrolysate organosiloxane descend greatly.

What the equipment of prior art adopted is azeotropic acid hydrolysis technology, and first can produce a large amount of spent acid and waste water, is unfavorable for environmental protection.Second dissolves a large amount of siloxanes in sour water makes the output of final hydrolysate reduce greatly, does not reach expected effect, thereby can increase production cost.

Because agitator speed is inhomogeneous, monitoring temperature is unreasonable, make that reaction is insufficient in addition, yield poorly, of poor quality.

Summary of the invention

In order to overcome the above problems, the invention provides that a kind of cost is low, output is high, is beneficial to the hydrolysis reactor of environmental protection.

To achieve these goals, the technical scheme of the invention employing is: a kind of hydrolysis reactor: form an airtight reaction vessel by low head, lower shell, awl section, upper shell, flange and blind flange; The low head bottom connects to support to be taken over, and supports to take over the organic matter inlet to be connected with the sour water inlet, and blind flange is provided with standby mouth, thermometer mouth, agitator connector and hydrolysate outlet, and the even cloth in the upper shell outside is provided with two support ear seats.

Among the present invention, can effectively reduce organosilyl production cost, realize the effect of energy-saving and emission-reduction, the adjusting of mainly taking active carbon adsorption or polystyrene-based resin adsorption method to control speed, time and the temperature of stirring simultaneously reaches the content that reduces siloxanes in the sour water, this device adopts and stirs the PROCESS FOR TREATMENT hydrolysate, content of siloxane can be reduced to below 5/10000ths in lower floor's sour water, and most of siloxanes is directly separated out and is dissolved in hydrolysate, avoid the loss of siloxanes, can improve hydrolysate yield 0.5%～1.5%.

The beneficial effect of the invention is:

1, the invention is provided with one in the end socket bottom and takes over assembly, taking over assembly is made up of organic matter inlet, sour water inlet and support adapter, can make the fully reaction in reactor of organic matter and sour water, prevent that organic matter and sour water from mixing before entering reactor.Support the effect of playing choked flow and support of taking over.

2, the technology of saturated acid hydrolysis (active carbon adsorption or polystyrene-based resin adsorption method) is adopted in the invention, has replaced original azeotropic acid hydrolysis technology, and no spent acid and waste water produce, not only economy but also environmental protection.

3, the invention is with short production cycle, has improved organosilyl output.

4, the invention is provided with the agitator connector and is used to install agitator, and two kinds of materials are fully reacted.
