The present invention relates to an electrospinning apparatus capable of: reusing and recycling VOCs, which are generated when a spinning solution sprayed from the nozzle of a nozzle block in the electrospinning apparatus is stacked on a long sheet, and a spinning solution which has overflowed without being nano-fiberized by condensing/liquefying same and then adding the resulting products to the spinning solution; removing an upper insulating member inside a case for attaching a collector thereto by forming the lower part of the case for the electrospinning apparatus with a conductor and the upper part thereof with an insulator, and thereby simplifying the overall configuration of the electrospinning apparatus; producing nanofibers having different polymers or diameters by alternately installing a bottom-up electrospinning apparatus and an up-bottom electrospinning apparatus and alternately spraying the spinning solution; producing complementary and advanced nanofiber products by performing bottom-up and up-bottom electrospinning in one process; expanding the filtration area of a filter medium when fabricating same with the nanofibers by forming corrugations on the produced filter medium; and consequently ensuring the improved filtration area of the filter medium and thereby improving the performance of the filter medium and simultaneously prolonging the lifespan thereof. |
