Claims (8)

1. Способ непрерывного перемещения жидкости при вываривании пульпы в автоклаве, отличающийся тем, что жидкость, которую используют на определенном этапе процесса, циркулирует между контейнерами или резервуарами, расположенными на приточной и выходной сторонах автоклава, и когда доходят до этого определенного этапа процесса, автоклав присоединяют к системе циркуляции между контейнерами или резервуарами, которые связывают с этим определенным этапом процесса.1. The method of continuous movement of the liquid during pulp digestion in an autoclave, characterized in that the liquid that is used at a certain stage of the process is circulated between containers or tanks located on the supply and output sides of the autoclave, and when they reach this particular stage of the process, the autoclave is attached to the circulation system between containers or reservoirs that bind to this particular process step. 2. Способ согласно п. 1, отличающийся тем, что использованную жидкость непрерывно выгружают из контейнера или резервуара, расположенного на выходной стороне автоклава и посредством непрерывного добавления доз химикалий и последующего непрерывного регулирования температуры с помощью теплообменников, восстанавливают ее первоначальные свойства, и возвращают ее в систему циркуляции в контейнер или резервуар, расположенный на приточной стороне автоклава. 2. The method according to p. 1, characterized in that the used liquid is continuously discharged from a container or tank located on the output side of the autoclave and by continuously adding doses of chemicals and subsequent continuous temperature control using heat exchangers, restore its original properties and return it to circulation system in a container or tank located on the supply side of the autoclave. 3. Способ согласно п. 1 или 2, отличающийся тем, что часть израсходованной жидкости непрерывно ответвляют на выходной стороне и непрерывно подают во вторую систему циркуляции между контейнерами или резервуарами, расположенными на приточной и выходной стороне того же и/или другого автоклава. 3. The method according to p. 1 or 2, characterized in that a part of the consumed liquid is continuously branched on the output side and continuously fed into the second circulation system between containers or tanks located on the supply and output side of the same and / or another autoclave. 4. Способ согласно п.3, отличающийся тем, что недостающее объемное количество заменяют посредством непрерывной подачи новых химикалий, и/или промывочного раствора, и/или жидкости из другой системы циркуляции. 4. The method according to claim 3, characterized in that the missing volume quantity is replaced by continuously supplying new chemicals and / or washing solution and / or liquid from another circulation system. 5. Способ согласно п.3, отличающийся тем, что вторую систему циркуляции связывают с тем же определенным этапом процесса, что и первую систему циркуляции. 5. The method according to claim 3, characterized in that the second circulation system is associated with the same specific process step as the first circulation system. 6. Способ согласно п.3, отличающийся тем, что вторую систему циркуляции связывают с другим определенным этапом процесса, чем первую систему циркуляции. 6. The method according to claim 3, characterized in that the second circulation system is associated with another specific process step than the first circulation system. 7. Способ согласно одному из пп.1-6, отличающийся тем, что на выходной стороне системы(м) циркуляции между контейнерами или резервуарами часть отработанной жидкости непрерывно ответвляют и непрерывно подают в установку химической переработки для восстановления химикалий, причем недостающее количество объема заменяют в контейнере или резервуаре тем, что добавляют промывочный раствор и/или избыточную жидкость из другой системы циркуляции. 7. The method according to one of claims 1 to 6, characterized in that on the output side of the system (m) of circulation between containers or reservoirs, part of the spent liquid is continuously branched and continuously fed to a chemical processing unit to restore chemicals, and the missing amount is replaced in container or reservoir by adding a washing solution and / or excess liquid from another circulation system. 8. Способ согласно одному из пп.1-7, отличающийся тем, что на выходной стороне автоклава предусматривают профиль распределения концентрации примеси химикалий, который возрастает со временем реакции. 8. The method according to one of claims 1 to 7, characterized in that on the output side of the autoclave provide a distribution profile of the concentration of chemical impurities, which increases with the reaction time.
