Description
Technical field
The invention belongs to the preparation field of isocyanuric acid three-glycidyl ester, be specifically related to a kind of drying equipment and drying means of isocyanuric acid three-glycidyl ester.
Background technology
The isocyanuric acid three-glycidyl ester of in isocyanuric acid three-glycidyl ester (TGIC) preparation technology, preparing through Crystallization Procedure is moist shape, contains a large amount of solvents, therefore need carry out dried to the isocyanuric acid three-glycidyl ester of humidity.The dry heated-air circulation oven that adopts mostly of traditional isocyanuric acid three-glycidyl ester is discharged to the solvent evaporate to dryness in the air outward; The material uneven phenomenon of being heated appears in this drying means easily when isocyanuric acid three-glycidyl ester is handled; Cause the isocyanuric acid three-glycidyl ester particle that local the thawing and problem such as the volatilization of solvent is inconsistent taken place; And the time of dry isocyanuric acid three-glycidyl ester is long, the energy that will consume big.In addition volatile solvent is waved and directly entered in the air, not only contaminated environment, and waste solvent has increased the production cost of isocyanuric acid three-glycidyl ester.
Summary of the invention
But the drying equipment that primary and foremost purpose of the present invention provides a kind of isocyanuric acid three-glycidyl ester thermally equivalent and the solvent of drying and volatilizing is recycled.
For realizing having the purpose of above-mentioned performance drying equipment; The present invention has adopted following technical scheme: a kind of drying equipment of isocyanuric acid three-glycidyl ester; It is characterized in that: comprise the isocyanuric acid three-glycidyl ester wet feed is carried out dry microwave drier and the condensing unit that reclaims solvent; The admission line of described condensing unit is connected with drying device, and the condensate outlet pipeline of condensing unit is connected to storage device.
The electromagnetic field of high frequency that produces through microwave makes moving and mutual friction mutually of isocyanuric acid three-glycidyl ester interior molecules; Thereby make the each several part temperature of isocyanuric acid three-glycidyl ester material evenly raise; After temperature of charge raise rapidly, lower boiling solvent will flash to escaping gas, thereby isocyanuric acid three-glycidyl ester is dry; Escaping gas gets into condensation in the cooling device, is stored in after the condensation in the storage device in order to recycling.
Another object of the present invention provides a kind of drying means of isocyanuric acid three-glycidyl ester, specifically may further comprise the steps:
Vacuumize: the isocyanuric acid three-glycidyl ester wet feed is put into the microwave drying device, open vavuum pump microwave drier is evacuated, start condensing unit;
Microwave drying: start microwave drier, set the temperature of microwave drier, the isocyanuric acid three-glycidyl ester wet feed is carried out micro-wave vacuum handle;
Take out finished product: after treating the dry end of isocyanuric acid three-glycidyl ester wet feed, close vavuum pump and microwave device, take out the isocyanuric acid three-glycidyl ester finished product and get final product.
Through microwave drier is evacuated, reduce the boiling point of solvent, under the cryogenic conditions material is carried out drying, prevent that isocyanuric acid three-glycidyl ester from melting and shortening the time of drying, enhances productivity.
The present invention can make that the whole material of isocyanuric acid three-glycidyl ester is heated evenly, drying time is short, and effectively solvent is reclaimed, and saves production cost.
