Description

Technical Field

[0001] The present invention belongs to the field of chemical industry, and relates to a devolatilizer for a multi-component fluid and the application of the devolatilizer, specifically to a thin film devolatilizer for a polymer high-viscosity fluid and the application of the thin film devolatilizer, and more specifically to a static thin film devolatilizer for a polymer high-viscosity fluid and the application of the static thin film devolatilizer. Background Art

[0002] The global chemical output is huge, and most products are produced by solution method, slurry method, precipitation method, emulsion suspension method or liquid phase bulk method. During the production process, the product needs to be separated from the solvent or monomer. If the melting point of the solvent or monomer is not too high, it does not decompose or react under appropriate heating conditions, and a devolatilizer is generally used to separate the solvent, monomer and oligomer from the product. Therefore, the devolatilizer is very important, and the devolatilization effect directly affects the quality, energy consumption, environment and economic benefits of the product. Especially in the polymer production industry, since polymer materials are highly viscous even at higher temperatures, it is difficult to devolatilize, and an efficient devolatilizer is required.

[0003] According to the dynamic and static state of the devolatilizer during the devolatilization process, it is divided into static devolatilization and dynamic devolatilization. The devolatilizer is divided into static devolatilizer and dynamic devolatilizer. Static devolatilizer relies on the material's own gravity to transport the material during the devolatilization process. Dynamic devolatilizer relies on the operation of other equipment components in contact with the material to transport the material, that is to say, the dynamic devolatilizer usually uses a rotating device to drive the polymer material to form a film in the devolatilizer. The rotating film formation increases the gas-liquid interface update rate in the devolatilizer, enhances the mass transfer and heat transfer efficiency of the polymer, and strengthens the devolatilization process. At present, according to the principle of devolatilization, static devolatilizers mainly include flash evaporators, falling film or falling strip devolatilizers. Static devolatilizers are mainly used for devolatilization of polymers with low viscosity and strong flowability. Flash evaporators are suitable for devolatilization of polymer materials with a viscosity lower than 100Pa·s. Falling film devolatilizers are suitable for devolatilization of polymer materials with a viscosity less than 100Pa·s. Falling strip devolatilizers are mainly used for foaming devolatilization of polymer materials with a viscosity above 100Pa·s. The dynamic devolatilizer is divided into a rotating film devolatilizer. The scraper type rotating film devolatilizer is driven by a motor to rotate the scraper on the rotating shaft along the inner wall of the devolatilizer. The polymer material is fed from the wall of the devolatilizer. Under the push of the scraper, the polymer material is smeared into a thin film on the inner wall of the devolatilizer. The viscosity of the scraper type rotating film devolatilizer is widely applicable and can handle 10,000Pa·s polymer melt. The energy consumption is very high due to the rotation. The horizontal surface renewal type devolatilizer mainly includes horizontal disc reactors, horizontal cage devolatilizers, etc., and the applicable polymer material viscosity range is 5 to 300Pa·s. The exhaust extrusion type devolatilizer is a screw extruder, which mainly includes single screw extruders, twin screw extruders and multi-screw extruders. Summary of the invention

[0004] The inventors of the present invention, Lei Jianlan and Huang Sihuang, accidentally thought of a glass roof with an appropriate slope. When it rains, rainwater forms a thin film on the glass roof. The area of ​​the formed film is much larger than that of rainwater falling directly on the ground. The glass roof is in a static state, and rainwater forms a thin film on the glass roof. Therefore, we creatively designed and manufactured a static thin film devolatilizer. The static thin film devolatilizer disclosed in the present invention is a static single-layer thin film devolatilizer or a static multi-layer thin film devolatilizer; the surface layer of the film plate of the static thin film devolatilizer is flat or trapezoidal or wavy or uniformly convex, preferably flat; the shape of the film plate of the static thin film devolatilizer is fan-shaped, rectangular, square or circular, and each layer of the film plate in the static thin film devolatilizer is fully or partially covered, wherein the partial coverage means that the area of ​​each layer of the film plate is one-fifth to four-fifths of the maximum cross-sectional area of ​​the static thin film devolatilizer; one end of each layer of the film plate is fixed It is installed on the support column and the other end is fixedly installed on the inner wall of the devolatilizer; the distance between each film plate and the inlet material distributor can be changed according to the viscosity characteristics of the material; each film plate has a hole near or in contact with the inner wall of the devolatilizer, and the size of the hole can be changed according to the inflow of the material to be processed or the viscosity of the material, and the shape of the hole is circular, elliptical, rectangular or square, and each film plate can have one or more holes; the film plates between the layers of the static multi-layer film devolatilizer can be installed at different positions or the lower film plate can be installed directly below the upper film plate. The volatiles are extracted from the top of the static film devolatilizer by the vacuum system. The material melt after the volatiles are removed flows into the storage tank area of ​​the static film devolatilizer, and then directly sent to the next operating unit from the bottom of the storage tank area of ​​the static film devolatilizer or sent by a delivery pump.

[0005] The invention is based on the high-tech research and development foundation of the company, and accidentally discovered and created a static film devolatilizer for high-viscosity material fluid.

Starting from the feed inlet, the first 1 to 7 sections are vacuumed to further remove the volatiles in the material melt to obtain a product with a volatile content of less than 0.1% by mass.

18. The static thin film devolatilizer according to claim 1, characterized in that: The static film devolatilizer operation process is as follows: (1) Turn on the heat source, the static film devolatilizer is heated to 100-350°C, and the top outlet of the static film devolatilizer is connected to the vacuum system and is in a normal state; (2) Open the material distributor, and the high-viscosity fluid or high-viscosity melt material sent from the reactor enters the devolatilizer from the material fluid inlet at the top of the static film devolatilizer through the material distributor. The operating pressure of the high-viscosity fluid or high-viscosity melt material at the material fluid inlet of the static film devolatilizer and the material distributor is 1-10MPa, and the material temperature is kept between 100-350°C. The volatile content of the high-viscosity fluid or high-viscosity melt entering the inlet of the static film devolatilizer is between 10-95%. The material is sprayed onto the film plate by the material distributor to form a thin layer of material on the film plate, and the volatiles are removed to obtain a material melt with a volatile content of less than 6% by mass. The operating pressure in the static film devolatilizer is 0.1-0.8MPa; (3) the material fluid after the volatile matter is removed falls into the storage area of ​​the static film devolatilizer, and the material melt is discharged from the bottom outlet of the static film devolatilizer and directly sent to the next operation unit or sent by a delivery pump, wherein the next operation unit is a screw extruder or a storage tank, and the temperature of the storage area of ​​the static film devolatilizer is 100-350° C.; wherein the screw extruder is divided into 2-8 sections between the feed inlet and the outlet of the screw extruder, and the first 1-7 sections starting from the feed inlet are vacuumed to remove the volatile matter in the material melt to obtain a product with a volatile matter of less than 0.1%; the screw extruder is divided into 2-8 sections between the feed inlet and the outlet, and the operating temperature of each section is the same or different, and the operating temperature is 100-350° C.
