ABSTRACT:
A grid falling film devolatilizer including a tower housing, a liquid distributor for distributing liquid within the tower housing, and one or more internal towers arranged in the tower housing in a parallel manner, for continuously forming and regenerating a large surface of film material using liquid from the liquid distributor. Each internal tower has (i) a round, square or rectangle cross section, (ii) four corners, (iii) four pillars standing at the four corners of the internal tower, respectively, and (iv) multiple grid trays supported within the internal tower and numbering between 2 to 500. Each pair of neighboring grid plates having an interval in the range of about 20 to 500 mm. Also, each grid tray includes a pair of beams, a plurality of grid bars and corresponding guide members.
