Ultraviolet transmission plate receiving frame and photopolymerization reaction system including the same {ULTRA VIOLET RAYS TRANSMISSION PLATE ACCOMODATING FRAME AND PHOTOPOLYMERI-ZATION SYSTEM INCLUDING THE SAME}

The present invention relates to an ultraviolet transmission plate receiving frame and a photopolymerization reaction system comprising the same.

Super absorbent polymer (SAP) is a special polymer material that has excellent absorbency and water retention, and is widely used in diapers for infants and adults, women's products, etc. As a typical method for manufacturing such super absorbent polymers, a radical photopolymerization initiator and There is a photopolymerization reaction in which polymerization is performed by irradiating ultraviolet rays in the presence of peroxide.

The photo polymerization reaction proceeds after agglomeration of the monomer composition (hereinafter 'reactant'), and when the reactants are supplied to the polymerization reactor, a plurality of UV lamp kits installed on the front end of the polymerization reactor 10 as shown in FIG. It proceeds in the lower region of (20). Here, the UV lamp kit 20 may include a UV lamp therein and a UV transmission plate for protecting the UV lamp at the bottom, or a UV transmission plate receiving frame containing the UV transmission plate.

Meanwhile, in the photoreaction process, water vapor and a small amount of monomer vapors are generated as by-products. In order to remove the generated by-products, a supply nozzle 11 and a discharge nozzle 12 for supplying heating air are formed on an upper side of the sidewall surface of the polymerization reactor 10, and by-products are supplied together with heating air supplied into the polymerization reactor. It is moved and discharged to the outside.

However, in the case of the UV-transmitting plate, contamination due to evaporation by-products is inevitable, and due to the contamination of the UV-transmitting plate, an appropriate amount of UV light cannot be reached as a reactant, so that a suitable environment for the polymerization reaction cannot be formed. Accordingly, the UV-transmitting plate needs to be periodically cleaned. In order to wash or replace the UV-transmitting plate, there has been a hassle of going through the process of separating the UV lamp kit 20 from the polymerization reactor 10. In addition, when the UV lamp kit 20 is separated from the polymerization reactor 10, the photoreaction process cannot be continuously performed, so the process must be stopped first, and the UV transmission plate must be replaced, and then the process must be performed again. Cost losses also occur.
