Water-removing apparatus for papermaking process |
摘要 |
A process and an apparatus for removing water from a fibrous web are disclosed. The process comprises providing a fibrous web having a moisture content from about 10% to about 90%; providing an oscillatory flow-reversing impingement gas having frequency of from 15 Hz to 1500 Hz; providing a gas-distributing system comprising a plurality of discharge outlets designed to emit the oscillatory flow-reversing impingement gas onto the web; and impinging the oscillatory flow-reversing gas onto the web through the plurality of discharge outlets, thereby removing moisture from the web. The apparatus comprises a web support designed to receive a fibrous web thereon and to carry it in a machine direction; at least one pulse generator designed to produce oscillatory flow-reversing air or gas; and at least one gas-distributing system in fluid communication with the pulse generator for delivering the oscillatory flow-reversing air or gas to the web. The gas-distributing system terminates with a plurality of discharge outlets juxtaposed with the web support such that the web support and the discharge outlets form an impingement distance therebetween, the plurality of the discharge outlets comprising a predetermined pattern defining an impingement area of the web.
