A lubricating device lubricates a circulating clothing of a machine for manufacturing a fibrous web. The device has a body with a feed chamber that has an inlet for supplying a pressurized liquid lubricant to the feed chamber and an outlet for discharging the lubricant therefrom. The body further has a nozzle chamber to which a nozzle for discharging the lubricant is connected. The nozzle has a flow-conducting connection to the feed chamber via the nozzle chamber and the outlet. Within the body, a diffuser is provided for diffusing the lubricant supplied through the outlet along the body, the diffuser being arranged between the outlet and the nozzle.

A cleaning device, in particular for a suction roller, for a machine for producing or processing a fibrous web, includes a distribution line and a number of cleaning nozzles which can be supplied with a cleaning fluid via the distribution line. At least one cleaning nozzle, in particular all of the cleaning nozzles, are in the form of oscillating nozzles. A suction roller and a method for cleaning a suction roller are also provided.

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.

[Problem] To provide a nozzle cap that hardly causes clogging in the nozzle hole even when used for a long time, a nozzle device having such a nozzle cap and a spraying method of a chemical solution. [Solution] The present invention relates to a nozzle cap 100 to be used for a nozzle device for spraying a chemical solution to wet paper, wire, felt, press rollers, dryer rollers, canvas or guide rollers in a paper machine, which is provided with: an air cap part 10 that is provided with a first base part 11 having a cylinder shape with a lid, with a nozzle hole 13 formed on the first base part 11; and a liquid cap part 20 that is provided with a second base part 21 having a disc-shape and a protruding part 22 that is formed on the second base part 21, and in this structure, a plurality of chemical solution spraying air holes 22b are formed on the second base part 21, and into a space part S formed between the first base part 11 and the second base part 21, with the first base part 11 and the second base part 21 being fitted to each other, a chemical solution is flowed from the protruding part 22, and air is also flowed in from the chemical solution spraying air holes 22b so that the chemical solution from the nozzle holes 13 is sprayed by the air, and the lid part 11a has a lower surface having a plane shape so that the air flowed in from the chemical solution spraying air holes 22b are made to collide with the lower surface of the lid part 11a through the space part S.

A method is disclosed of facilitating the removal of contaminates from a belt in a papermaking system. The method includes the step of providing a fluid in a shaped fan such that the interface between the fluid and the belt is non-linear and at least generally forms the shape of an arc.
