Pulp washer mist eliminator and foam remover system
Method and apparatus for removing liquid from a gas/liquid flow for use in pulp washers, deinking cells, and the like are disclosed. A gas/liquid separator includes a separation chamber with a flow director providing a gas/liquid flow from a receptacle into the separator in a direction causing impingement of entrained liquid particles on a chamber wall such that liquid particles coalesce into liquid droplets that travel downward by the force of gravity to a separated liquid drain and drained outside the receptacle. A tangential flow inlet provides greater impingement than a cyclonic flow introduced at the lower end of the gas/liquid separator in initially directed upwards. Separated liquid could further be taken outside the pulp washer system for further processing or disposal based on the chemical content of the separated liquid.

Sheet manufacturing apparatus
A sheet manufacturing apparatus includes a first transport unit, a second transport belt disposed with a part thereof shifted from the first transport unit toward the downstream side in a transport direction of the web, a suction chamber positioned in an inner side of the second transport belt and configured to create suction inside the suction chamber to suck the web onto the second transport belt, and a current plate positioned inside of the suction chamber to adjust an air current. The current plate has a plurality of holes, and is spaced apart from a surface of the second transport belt such that the air current is diffused between the current plate and the surface of the second transport belt to achieve a uniform suction force in a width direction of the second transport belt.
Sheet manufacturing apparatus
A sheet manufacturing apparatus includes: a first transport unit that causes a first transport belt to circle around so as to transport a web; and a second transport unit that is disposed with a part thereof shifted from the first transport unit toward the downstream side in a transport direction of the web, sucks the web in a direction in which the web is spaced from the first transport belt, and transports the web. The second transport unit includes a suction chamber which is positioned on an inner side of a second transport belt circling around and of which an inner space is sucked by a suction unit such that the web is adsorbed onto the second transport belt. The suction unit is positioned on the outer side of the second transport belt in a direction orthogonal to the transport direction of the web along the surface of the web.

Sheet manufacturing apparatus
A sheet manufacturing apparatus includes: a first transport unit that causes a first transport belt to circle around so as to transport a web containing a fiber; and a second transport unit that is disposed with a part thereof shifted from the first transport unit toward the downstream side in a transport direction of the web, sucks the web in a direction in which the web is spaced from the first transport belt, and transports the web. The second transport unit includes a suction unit that generates a suction force and a suction chamber which is positioned on an inner side of a second transport belt circling around and of which an inner space is sucked by the suction unit such that the web is adsorbed onto the second transport belt. A part of the suction chamber faces the first transport belt.
