Description
испарение большей части растворител и образование иористой крошки полимера. В аппарате 2 первой ступени выделени осуществл етс теплова обработка движущейс сверху вниз пульпы вод ным паром и отделение потока парогазовой смеси от пульпы, котора из аппарата 2 направл етс самотеком в концентратор 3 пульпы первой ступени выделени . Парогазова смесь из. аппарата 2 направл етс на разделение и очистку, а отделенна в концентраторе 3 пульпы вода с помощью насоса 4 вновь подаетс в крошкообразователь 1. Избыток воды, образовавшийс в результате конденсации вод ного пара, отводитс из концентратора 3 на очистку.evaporating the majority of the solvent and forming a polymer crumb. In apparatus 2 of the first stage, separation of the pulp moving from top to bottom is carried out with steam and separation of the vapor-gas mixture stream from the pulp, which from apparatus 2 is directed by gravity into the concentrator 3 of the pulp of the first stage of separation. Steam-gas mixture of. The apparatus 2 is sent for separation and purification, and the water separated in the concentrator 3 pulp is pumped by pump 4 again to the crumbing agent 1. Excess water resulting from the condensation of water vapor is removed from the concentrator 3 to purification.
Отделенна от воды крошка полимера из концентратора 3 передаетс шнеком в аппарат 5. Туда же поступает вода из концентратора 9 пульпы второй ступени выделени . Образованна в аппарате 5 пульпа подвергаетс интенсивному смешению и измельчению диспергирующей мешалкой 6. Передача пульпы из аппарата 5 в аппарат 7 второй ступени выделени осуществл етс с помощью насоса 10.The polymer crumb separated from water from the concentrator 3 is transferred by the screw to the apparatus 5. Water from the concentrator 9 of the pulp of the second stage of the discharge is also supplied there. The pulp formed in the apparatus 5 is subjected to intensive mixing and grinding by a dispersing mixer 6. The pulp is transferred from the apparatus 5 to the apparatus 7 of the second stage of separation by means of a pump 10.
Обрабатыва сь вод ным паром в аппарате 7 крошка полимера движетс вверх и вместе с потоком воды, вод ного пара и незначительного количества паров растворител , направл етс из аппарата 7 в сепаратор 8, где происходит отделение пульпы от паров. Пульпа самотеком поступает в концентратор 9 пульпы второй ступени выделени , а пары забираютс эжектором 12 и направл ютс вместе с острым паром в крошкообразователь 1 и аппараты 2 и 7.Processing the water vapor in the apparatus 7 polymer crumb moves up and together with the flow of water, water vapor and a small amount of solvent vapor, is sent from the apparatus 7 to the separator 8, where the separation of the pulp from the vapor. The pulp flows by gravity into the concentrator 9 of the pulp of the second stage of separation, and the couples are taken by the ejector 12 and sent along with the direct steam to the crumb 1 and the devices 2 and 7.
Отделенна в концентраторе 9 крошка полимера направл етс на отжим и сушку, а осветлеина вода насосом И подаетс вThe polymer crumb separated in the concentrator 9 is sent for spinning and drying, and the clarified water is pumped by the AND pump into the
аппарат 5. Излишки воды из концентратора 9 отправл ютс на очистку.apparatus 5. Excess water from the concentrator 9 is sent for cleaning.
Разделение установки на два контура циркул ции воды - загр зненной и чистой - позвол ет осуществить более глубокое удаление растворител из крошки полимера за счет увеличени концентрационного напора в процессе массообмена и осуществлени отмывки крощки от зольныхSeparating the plant into two water circuits — contaminated and clean — allows deeper removal of the solvent from the polymer chips by increasing the concentration head during the mass exchange and washing off the ash
примесей, что особенно важно дл производства , например, медицинских и пищевых полимерных материалов. Кроме того, за счет разделени контуров воды в установке удаетс осуществить процессы выделени вimpurities, which is especially important for the production of, for example, medical and food polymeric materials. In addition, due to the separation of the water circuits in the installation, it is possible to carry out the separation processes in
первой и второй ступен х в оптимальных термодинамических режимах, что приводит к снижению энергозатрат.the first and second stages in optimal thermodynamic regimes, which leads to a decrease in energy consumption.
