Description
Technical field
It the utility model is related to the equipment that ring body mixture separates in a kind of organosilicon production, category organosilicon production technology neck
Domain.
Background technology
Organosilicon ring body is production organosilicon downstream product（Silicone oil, silicon rubber, silicones, silane coupler）Raw material,
Mainly include DMC, D3, D4, epipodium.Organosilicon ring body be hydrolyzed by dimethyldichlorosilane, hydrolysate cracks to obtain.Due to having
Machine silicon downstream product is higher to DMC quality requirement, it is necessary to by the further separation, impurity removal of ring body after cracking.The first step is first
Slough the low-boiling-point substance in ring body.Existing ring body rectifying take off it is low during, typically using rectification under vacuum, although this method operation temperature
Spend low, but capacity of returns is big, and target product is relatively simple, and main content is relatively low in the D3 sloughed, and impurity is more.It is and some in DMC products
Light component can not be removed, and downstream product quality is caused necessarily to influence.And existing separator system complex, construction investment are big,
Seriously corroded in equipment operation, and be easier to block, directly result in technical economic benefit and be evidently poor.Therefore, exploitation is a kind of new
Organosilicon ring body separating technology and equipment break showing for bad existing product economic benefit, equipment, corrosive pipeline and blocking
Shape is very necessary.
Utility model content
The equipment that the purpose of this utility model is a kind of organosilicon ring body mixture separation provided.The equipment includes carrying
Section, rectifying section are evaporated, stripping section is connected with rectifying section, and rectifying section diameter is less than stripping section；The filler of layer 2-4 is provided with stripping section
Layer；The packing layer of 1-2 layers is provided with stripping section；Rectifying section top is provided with heat exchanger, and heat exchanger is graphite material, heat exchanger tube
Specification Φ 32, Φ 38, Φ 50.
Described heat exchanger with rectifying is intersegmental is provided with collecting tank, collecting tank bottom is additionally provided with extraction mouth.
Described heat exchanger side wall is provided with refrigerant import and refrigerant exit, and drain is provided with the top of heat exchanger.
Described stripping section top is provided with material inlet, and bottom is provided with bed material outlet；Packing layer in stripping section
Bottom is provided with gas phase import, liquid level mouth one, liquid level mouth two.
Described stripping piece housing is stainless steel, and rectifying section is to dissipate heap graphite with the packing layer in stripping section top,
The scattered heap graphite on stripping section top contacts connection with the wire packing of bottom.The wire packing of stripping section is stainless steel, than
Surface area 500-700 ㎡/m3, graphite packing specification is Φ 32- Φ 50 Raschig ring, and the graphite packing specification of stripping section is more than
Rectifying section.
The utility model has a good application prospect and application value, compared to the prior art the advantage is that：（1）If
Standby diameter and material select difference up and down, have saved equipment investment cost.（2）Cooling and refined one, save pipeline and set
Standby investment, it also avoid feed blocking pipeline and equipment.（3）Atmospheric pressure device, filler separative efficiency is high, and target product is flexibly adjusted
It is whole.（4）According to technique and product performance reasonable selection equipment and internals material, not only investment reduction but also equipment high temperature corrosion had been overcome
The defects of serious.
