PURIFICATION APPARATUS USING ADSORPTION AND FILTRATION, METHOD FOR CHANGING ADSORPTION MATERIAL OF THE PURIFICATION APPARATUS, AND METHOD FOR BACK WASHING OF THE PURIFICATION APPARATUS

摘要

PURPOSE: An absorption filtering apparatus, an absorption material exchanging method thereof, and a backwashing method for same are provided to improve the backwashing efficiency and the exchanging efficiency of absorption materials. CONSTITUTION: An absorption filtering apparatus includes a storage(110) and a pressure crusher(132). The pressure crusher pressurizes and crushes absorption materials in the storage. The pressure crusher includes a driving shaft(132b), a driving motor(132a), and a screw(132c). The driving shaft installed in the storage in a rotatable manner. The driving motor selectively rotates the driving shaft to a first direction and a second direction which is opposite to the first direction. The screw is located along the peripheral of the driving shaft.
