Description

В процессе варки целлюлозы сульфитным сиособом отбираема  из варочных котлов жидкость (щелок) содержит от 2 до 4% сернистого газа (SOa).In the process of pulping by sulphite sioosom, liquid (lye) is extracted from digesters from 2 to 4% sulfur dioxide (SOa).

По предлагаемому способу получение 100%-ного сернистого газа (SO2) из варочных жидкостей производитс  посредством регенерации этого сернистого газа, содержащегос  в щелоках, отбираемых от варочных котлов в процессе варки целлюлозы.According to the proposed method, the production of 100% sulfur dioxide (SO2) from cooking liquids is carried out by regenerating this sulfur dioxide contained in the liquors taken from the boilers during the pulping process.

Особенность предлагаемого способа заключаетс  в том, что отбираемый щелок направл ют в реципиент, поддерживаемый под пониженным давлением или вакуумом, причем отданный жидкостью сернистый газ (SO2) отсасывают в регенерацию дл  укреплени  кислоты.A feature of the proposed method is that the liquor to be withdrawn is sent to the recipient, maintained under reduced pressure or vacuum, and the sulfur dioxide (SO2) given off by the liquid is sucked off into the regeneration in order to strengthen the acid.

Реципиент представл ет собой котел, рассчитанный на давление до 3-4 атм, футерованный внутри кислотоупорным материалом. Емкость реципиента желательно иметь в пределах емкости варочного котла.The recipient is a boiler, designed for pressures up to 3-4 atm, lined inside with acid-resistant material. The capacity of the recipient is desirable to have within the capacity of the digester.

Работа осуществл етс  по следующему режиму.Work is carried out in the following mode.

Понижение давлени  в варочных котлах при подъемах температуры от 105 до 125° и от 125 до конечной температуры производитс  путем сбросов жидкости из варочных котлов в верхнюю часть реципиента. Последний поддерживаетс  под пониженным давлением или под вакуумом специальной эдукторной установкой. В результате пониженного давлени  и высокой температуры жидкость отдает 100%-ный газ SO2, который отсасываетс  в регенерацию и тем самым происходит укрепление кислоты.Pressure reduction in digesters at temperature rises from 105 to 125 ° and from 125 to the final temperature is performed by discharging liquid from the digesters into the upper part of the recipient. The latter is maintained under reduced pressure or under vacuum by a special eductor unit. As a result of reduced pressure and high temperature, the liquid gives off 100% SO2 gas, which is sucked into the regeneration and thereby strengthens the acid.

Предмет изобретени Subject invention

Способ регенерации сернистого газа, содержащегос  в щелоках, отбираемых из варочных котлов в процессе варки целлюлозы, отличающ .ийс  тем, что отбираемый щёлок направл ют в реципиент, поддерживаемый под пониженным давлением или вакуумом, причем отданный жидкостью газ S02 отсасывают в регенерацию, с целью укреплени  кислоты .The method of regeneration of sulfur dioxide contained in the liquors withdrawn from the boilers during the pulping process, is characterized in that the withdrawn liquors are sent to the recipient maintained under reduced pressure or vacuum, the gas S02 being drained with liquid is sucked off into the regeneration in order to strengthen acid.
