DESTRUCTIVE DEVICE, FOAM GAS COLLECTING DEVICE, AND FOAM GAS SEPARATING AND COLLECTING SYSTEM

摘要

A destructive device, wherein an object (1) including a foam to be treated is pre-compressed in the direction of the thickness and fed to the opposed part of a pair of compression rolls (21, 22), partition walls forming independent air bubbles in the foam are fractured by the compression rolls (21, 22) and the foaming gas is captured in a cover (3) installed on the outlet side of the compression rolls (21, 22), the foaming gas together with a medium gas (41) for collection is pressurized by a pressurizing device (5), sent to a cooling device (15) and separated by a cooling and liquefying device (6), and the medium gas for collection from which the foaming gas is separated is returned into the cover (3), whereby, since the foaming gas is liquefied and separated in a pressurized state by the cooling and liquefying device (6) by capturing the foaming gas in a high density inside the cover (3), the device can be remarkably downsized and simplified, and the device cost and the operation cost can also be remarkably reduced. <IMAGE>
