<p>PURPOSE:To reduce the pressure drop of the packing material and to improve its heat transfer and heat exchange performance by providing an opening on the front of the projecting part on the air flow side of the plate-type packing material having recessed and projection face, and forming the packing material with a mixture of water absorptive resin and non-water absorptive resin. CONSTITUTION:Air flow 5 flows obliquely forward from the right-hand side of the plate-type packing material 1, and the opening 6 is provided on the front 3 of the projecting part 2 on the air flow side. The packing material 1 is made of a base material obtained by forming a mixture of water absorptive resin and non-water absorptive resin. Since the opening 6 is provided on the front 3 of the projecting part 2 of the packing material 1 on the air flow side, a part of the air flow having collided with the front 3 passe through the opening 6 and sent to the rear, hence the pressure drop of the air flow is reduced, and the air flow entering the recessed face on the rear of the projecting part 2 is brought into sufficient contact with water or a soln. In addition, since the packing material 1 is made of a mixture of water absorptive resin and non-water absorptive resin, the surface is made hydrophilic, a water film is formed and held on the whole surface, and heat transfer or material transfer is efficiently performed.</p> |
