The invention relates to a process for collecting process water at a paper machine or the like, wherein water from several suction elements (2 . . . 2n, 2m) provided at a wire (1) is led in such a way that an unbroken liquid column is maintained in the outlet pipes (8 . . . 8n, 8m) of the suction elements and is made to join a common collecting vessel (9, 9m). The liquid levels (20 . . . 20n) of the outlet pipes am regulated by regulating the liquid level (11) in at least one separate level vessel (10) towards which the water from the respective outlet pipes is led in at least one closed and essentially horizontal collecting channel (9, 9m) which is common for several outlet pipes. (8 . . . 8n, 8m), the liquid in said collecting channel (9, 9m) at the same time forming the lower part of said unbroken liquid column. The invention also relates to an arrangement for collecting process water, wherein the collecting vessel is composed of at least one essentially closed collecting channel (9, 9m) to which outlet pipes connect below the liquid level.
A process for collecting process water at a paper machine or the like, wherein water from several suction elements (2 . . . 2n, 2m) provided at a wire (1) is led in such a way that an essentially unbroken liquid column is maintained in the outlet pipe (8 . . . 8n, 8m) of each respective suction element (2 . . . 2n, 2m) and is made to join a common collecting vessel (9, 9m), wherein the liquid levels (20 . . . 20n) of the outlet pipes (8 . . . 8n, 8m) are regulated by regulating the liquid level (11) in at least one separate level vessel (10) towards which the water from the respective outlet pipes (8 . . . 8n, 8m) is led in at least one closed and essentially horizontal collecting channel (9, 9m) which is common for several outlet pipes (8 . . . 8n, 8m) in such a way that the liquid in said collecting channel (9, 9m), which as such leads the liquid onwards, at the same time forms the lower part of said unbroken liquid column.
An arrangement at a paper machine for collecting process water, said arrangement comprising suction elements (2 . . . 2n, 2m) provided at a wire section or the like, said suction elements being connected by essentially vertical outlet pipes (8 . . . 8n, 8m) to at least one collecting vessel, wherein said collecting vessel is composed of at least one essentially closed collecting channel (9, 9m) to which said outlet pipes connect below the liquid level of the channel.
