Method and system of slurry circulation
The invention relates to a method of slurry circulation, in which a aqueous slurry for a sizing agent, is located in a slurry tank (10), the aqueous slurry is pumped from the slurry tank (10) by a pump (11) to a circulation line (12) and to an outlet line (14), via which the slurry is guided to furt...

| description | The invention relates to a method of slurry circulation, in which a aqueous slurry for a sizing agent, is located in a slurry tank (10), the aqueous slurry is pumped from the slurry tank (10) by a pump (11) to a circulation line (12) and to an outlet line (14), via which the slurry is guided to further processing of the sizing agent before it will be applied onto the fiber web. The aqueous slurry is alternatively guided along the circulation line (12) back to the slurry tank (10). The route of the slurry flow is selected by the position of a valve (13) of the circulation line (12) such, that selection the flow of the aqueous slurry is selected to the outlet line (14) or to continue in the circulation line (12) back to the slurry tank (10). The invention also relates to a system of slurry circulation comprising a slurry tank (10), a pump (11), a circulation line (12), an outlet line (14), via which the slurry is guided to further processing of the sizing agent. The system further comprises a valve (13) of the circulation line (12) for selection the flow of the aqueous slurry to the outlet line (14) or to continue in the circulation line (12) back to the slurry tank (10).
Keksinnön kohteena on lietekiertojärjestelmä, jossa vesipitoinen liete liimausainetta varten, sijoitetaan liettosäiliöön (10), vesipitoinen liete pumpataan liettosäiliöstä (10) pumpulla (11) kiertolinjaan (12) ja poistolinjaan (14), jonka kautta liete ohjataan liimausaineen jatkoprosessointiin ennen sen applikointia kuiturainalle. Vesipitoinen liete vaihtoehtoisesti ohjataan kiertolinjaa (12) pitkin takaisin liettosäiliöön (10). Lietevirtauksen reitti valitaan kiertolinjan (12) venttiilin (13) asennolla siten, että vesipitoisen lietteen virtauksen valinta valitaan poistolinjaan (14) tai jatkamaan kiertolinjassa (12) takaisin liettosäiliöön (10). Keksinnön kohteena on myös lietekiertojärjestelmä, joka käsittää liettosäiliön (10), pumpun (11), kiertolinjan (12), poistolinjan (14), jonka kautta liete johdetaan liimausaineen jatkoprosessointiin. Järjestelmä edelleen käsittää kiertolinjan (12) venttiilin (13) vesipitoisen lietteen virtauksen valitsemiseksi poistolinjaan (14) tai jatkamaan kiertolinjassa (12) takaisin liettosäiliöön (10). |
