Description
Technical field
The utility model is related to Vingon field, and in particular, the utility model is related to a kind of for gathering inclined chlorine
The polymeric kettle of ethylene production.
Background technology
The key component of polyvinylidene chloride (abbreviation PVDC) is vinylidene chloride (VDC), due to symmetrical molecule
The presence of structure and hydrophobic group chlorine, makes it have crystallinity and fusing point higher, block water, oxygen resistance it is good, and to the obstruct of gas
Property is not influenceed by ambient humidity, is widely used in the fields such as food, medicine, military project.
In Vingon production process, polymeric kettle is main production equipment, the direct shadow of quality of its technical performance
Ring economy for the Yield and quality and operation for arriving Vingon etc..At present, the production of polyvinylidene chloride resin can be produced
Business, only external DOW chemical companies of the U.S. and Wu Yu companies of Japan, the country is Zhejiang Juhua Co., Ltd., Electrochemical Plant.It is existing
The annual production of global Vingon is about 100,000 tons, far can not also meet the market demand.What current above-mentioned manufacturer used
Vingon polymeric kettle, DOW chemical companies of the U.S. are 40m3Polymeric kettle, Japanese Wu Yu companies are 60m3Polymeric kettle, Zhejiang hugeization
The polymeric kettle that electrochemical factory of limited company uses is 30m3.In order to further improve Vingon yield, work life is improved
Yield, in the urgent need to exploitation 60m3Large-scale Vingon polymeric kettle above.
In addition, in the production process of Vingon, exist that viscous kettle, product particle be uneven, mass-and heat-transfer always
The problems such as difference, machine envelope are easily leaked, manhole opens difficult, has a strong impact on the quality and efficiency of Vingon production.Especially
It is that viscous kettle is seriously open question all the time in Vingon production process, in general Vingon production process,
Cleaning of the high intensity pressure (500bar) up to 4 hours will be carried out after being polymerized each time to kettle, polymeric kettle production capacity is influenceed
Performance.And the generation of above mentioned problem, except having outside the Pass with polymerization technique, the structure design also with polymeric kettle is relevant.Particularly stir
The structural shape for mixing device has a great impact to the effect of PVDC polymerization stirrings.The agitator of each structure is all only to a certain kind
Or several stirring operations have good effect, any agitator can not possibly be adapted to the stirring operation of all PVDC polymerizations.Pin
To specific stirring operation operating mode, select suitable agitator pattern particularly significant to PVDC polymerization techniques.Stirring in polymeric kettle
Mixing type formula typically has anchor formula, paddle, turbine type, push type and frame.
Anchor formula：The stirring of high viscosity fluid is generally used for, because the stirrer diameter is very big, therefore may be used only for low turn
Under fast operating mode.
Common pusher and paddle：Shearing force to fluid matasomatism is relatively low, it is difficult to be thoroughly mixed high viscosity fluid.
Resin viscosity rising particle is thicker in course of reaction, easy implode.
Turbine type：It is applied to rotating speed high stirring, rotating speed is too high to make the PVDC resin particles become irregular, phase between particle
Mutually it is bonded, reaction heat is difficult to remove, and easily produces implode.
Frame：Shearing force is too strong, easily deforms resin particle, is unfavorable for processing.
As Chinese patent notification number CN203754627U discloses a kind of PVDC reactors, including shell, several discharges
Ring group into discharge ring array and top cover, the inwall of the cylindrical and shell of discharge ring array contacts；Discharge ring includes discharge ring master
