Destructive device, foam gas collecting device, and foam gas separating and collecting system

A foaming gas separating and collecting system comprising:

• a destructive device comprising a pair of opposed compression rollers for compressing in the opposing direction, in an opposing portion of the pair of compression rollers, an object to be treated comprising a foam, and a compressing and carrying device, disposed upstream of the pair of compression rollers, for sending the object to the opposing portion of the pair of compression rollers;
• and
• a cover for covering at least an exit side of the pair of compression rollers;
• wherein the compressing and carrying device comprises a lower carrier potion and an upper carrier portion that are opposed to each other,
• a space between thc lower carrier portion and the upper carrier portion is narrower toward a side of the opposing portion of the pair of compression rollers,
• each of the lower carrier portion and the upper carrier portion comprises a plurality of floating members whose longitudinal direction corresponds to a carrying direction, a rotation shaft penetrating the plurality of floating members, and a plurality of eccentric cams disposed between the plurality of floating members and the rotating shaft, and
• the object is pre-compressed by the compressing and carrying device and then compressed by the pair of compression rollers in substantially the same direction as a direction of the pre-compression.
