Abstract
The utility model discloses a reactor for synthesizing diethyl carbonate and a stirrer of the reactor. The reactor comprises a reactor body and the stirrer, the stirrer consists of a stirring spindle and stirring blades arranged on the stirring spindle, each stirring blade comprises a blade main body and a corrosion-resistant layer made of polytetrafluoroethylene materials, and the corrosion-resistant layers are covered on surfaces of the blade main body. The reactor has the advantages that the polytetrafluoroethylene corrosion-resistant layers are coated on the surfaces of the stirring blades of the stirrer, accordingly, the shortcoming that original enamel glass blades are easy to corrode is overcome, abrasion resistance of the surfaces of the stirring blades is strengthened, and the service life of the stirrer is effectively prolonged.
Description
Technical field
It is synthetic with agitated reactor and agitator thereof that the utility model relates to a kind of diethyl carbonate.
Background technology
Diethyl carbonate (DEC) is a kind of organic synthesis intermediate; Be mainly used in agricultural chemicals, medicine, instrument and meter, electronics industry; In some fibre element and resin, make solvent, particularly add the cryogenic property that can improve the charge type lithium ion battery in the electrolyte, market demand is very big.In recent years research shows; Diethyl carbonate also can be used as the oxygenated additive of gasoline and diesel fuel; Substitute traditional additive methyl tertiary butyl ether(MTBE) (MTBE); Improve the combustibility of gasoline, DEC has more competitive advantage as one of substitute of MTBE than dimethyl carbonate and ethanol, has potential application prospect.Utilize in the phosgene production diethyl carbonate process existing, adopt common enamel reaction still and glassed agitator, the long-term and enamel glass friction of material liquid; Its surperficial glaze layer very easily damages; Especially agitator, the hydrogen chloride that produces in the production process very easily corrodes agitator inside, thereby needs often to change agitator; Serious restriction improving productivity increases production cost of products.
The utility model content
The purpose of the utility model is to overcome defective of the prior art, thereby provides a kind of diethyl carbonate synthetic with agitated reactor and agitator thereof.
An aspect according to the utility model; Provide a kind of diethyl carbonate the synthetic agitator of using; Comprise and stir main shaft and be arranged on the stirring vane on the said stirring main shaft that said stirring vane comprises blade body and covers the lip-deep corrosion-resistant coating that is formed by polytetrafluoroethylmaterial material of said blade body.
Another aspect according to the utility model; Provide a kind of diethyl carbonate the synthetic agitated reactor of using; Comprise kettle and agitator; Said agitator comprises the stirring main shaft and is arranged on the stirring vane on the said stirring main shaft that said stirring vane comprises blade body and covers the lip-deep corrosion-resistant coating that is formed by polytetrafluoroethylmaterial material of said blade body.
The advantage of the utility model is: the surfaces coated at the stirring vane of agitator is covered with anticorrosive PTFE erosion layer, has remedied the corrosion-prone deficiency of former enamel glass blade, has strengthened surperficial wearability again, has effectively prolonged the service life of agitator.
Description of drawings
Fig. 1 is the synthetic agitated reactor of using of the diethyl carbonate of the utility model.
Fig. 2 is the drawing in side sectional elevation of stirring vane of the agitator of the agitated reactor among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.It will be appreciated by those skilled in the art that following description and diagram are merely example and task of explanation, is not that intention limits the utility model by any way.
With reference to figure 1, the diethyl carbonate of the utility model synthesizes the kettle 1 that comprises vertical setting with agitated reactor, and label L has indicated the vertical central axial line of kettle 1.The top of this kettle 1 is provided with charging aperture 3, and the bottom is provided with discharge gate 6.
This diethyl carbonate is synthetic also to comprise agitator with agitated reactor.This agitator comprises stirring main shaft 4 and is arranged on the stirring vane 5 that stirs on the main shaft 4.Though two stirring vanes 5 only are shown in the embodiment in figure 1, one of ordinary skill in the art will readily recognize that the stirring vane that other quantity can be set as required.Stirring main shaft 4 extends to the inner chamber of kettle 1 along central axial line L from the outside of kettle 1.In the outside of kettle 1, an end that stirs main shaft 4 is connected to reducing motor 2.In the inner chamber of kettle 1, near the other end that stirs main shaft 4, be provided with said two stirring vanes 5, these two stirring vanes 5 are along the axially spaced-apart setting of stirring main shaft 4.When work, reducing motor 2 drives stirring main shaft 4 and is rotated, and rotates together by stirring main shaft 4 drive stirring vanes 5.
Fig. 2 shows the cross-sectional view of stirring vane 5 with the mode of amplifying, and this cross-sectional view is along perpendicular to the horizontal expansion direction intercepting of stirring vane 5.As can beappreciated from fig. 2, the stirring vane 5 lip-deep corrosion-resistant coating 52 that comprises blade body 51 and cover blade body 51.Blade body 51 can be processed by iron or other metal or other suitable material.This corrosion-resistant coating 52 mainly is for the corrosion to blade body 51 of the hydrogen chloride that prevents in utilizing phosgene production diethyl carbonate process, to produce.Therefore, corrosion-resistant coating 52 is preferably formed by the material of anti-hydrogen-chloride etching.In a preferred embodiment, this corrosion-resistant coating 52 is formed by polytetrafluoroethylmaterial material.This corrosion-resistant coating 52 can cover on the blade body 51 according to the coating method of any appropriate in the prior art.
When work, the material of participation reaction is transported in the agitated reactor through charging aperture 3, and reducing motor 2 drives and stirs main shafts 4 rotations, and the stirring vane 5 that stirring main shaft 4 drives on it rotates, thereby the material in the agitated reactor is stirred.Material after reaction is accomplished is discharged agitated reactor through discharge gate 6.In the course of the work; Because the outer surface of stirring vane 5 is provided with the corrosion-resistant coating 52 of polytetrafluoroethylmaterial material; Make the blade body 51 of stirring vane 5 itself not contact with material; So can effectively prevent material (for example hydrogen chloride) in the kettle 1 to the corrosion of stirring vane 5, thereby prolong the service life of agitator.And; Corrosion-resistant coating 52 wearabilities that form with polytetrafluoroethylmaterial material are good; With the working environment of material friction in; The structural intergrity that can keep corrosion-resistant coating for more time avoids corrosivity material such as hydrogen-chloride etching stirring vane inner, and this also can effectively prolong the service life of agitator.
