Claims (1)

Способ используется в производстве целлюлозы любым методом: сульфитным, сульфатным, натронным и др. Сокращение времени варки, упрощение технологии, снижение вредных выбросов и сокращение расхода химикатов и тепловой энергии достигаются тем, что после загрузки и уплотнения сырья в варочный котел подают сжатый нагретый газ, поднимают давление до рабочего, затем вводят нагретую до рабочей температуры варочную жидкость, после выдержки отработанную варочную жидкость удаляют, замещая ее нагретым сжатым газом, газовые сдувки систем варки целлюлозы и регенерации отработанной варочной жидкости направляют в газгольдер, откуда их забирают, сжимают и используют в системе варки в качестве сжатого газа, а избыток направляют на сжигание.The method is used in the production of pulp by any method: sulphite, sulphate, soda, etc. Reducing cooking time, simplifying technology, reducing harmful emissions and reducing the consumption of chemicals and thermal energy is achieved by supplying compressed heated gas to the digester after raise the pressure to the worker, then the cooking liquid heated to the working temperature is introduced, after holding the spent cooking liquid is removed, replacing it with heated compressed gas, gas blowings of the cooking systems are intact yulozy and regeneration of spent cooking liquid fed to a gasholder, where they are taken is compressed and used in the cooking system as pressurized gas, and the excess is sent for incineration.
