Description
4 и далее в зазор а. Из разбрызгивателей жидкость в распыленном состо нии опускаетс в желоб 10 дл сбора охлаждающей жидкости , охлажда и увлажн воздух внутри пленочиого рукава. Слой жидкости из зазора а стекает по внутренней поверхности корпуса , интенсивно охлажда его.4 and further into the gap a. From the sprinklers, the liquid in a spray state is lowered into the chute 10 to collect the coolant, cool and moisten the air inside the film tube. A layer of liquid from the gap and flows along the inner surface of the body, intensively cooling it.
При этом внутри рукава происходит циркул ци воздуха.At the same time, air circulates inside the tube.
Гор чий воздух захватываетс в верхней части рукава вентил тором 7 и подаетс в направлении, указанном стрелками (см. фиг. 1). При прохождении воздуха внутри корпуса происходит его охлаждение и увлажнение распыленным потоком охлаждающей жидкости. Из корпуса 2 охлажденный поток воздуха через щель, образованную корпусом и тарелкой 11, направл етс в полость между оребренной наружной поверхностью корпуса и пленочным рукавом. При движении воздуха в этой полости по волнообразным каналам б, образованным ребрами 12 на наружной поверхности корпуса, происходит ту.рбулизаци потока воздуха , что интенсифицирует процесс охлаждени пленки. Этому благопри тствует также интенсивное охлаждение корпуса изнутри стекающим слоем жидкости. Интенсивное охлаждение корпуса способствует процессу конденсации паров жидкости на наружной поверхности корпуса, предотвраща этим увлажнение внутренней поверхности пленочного рукава . Стекающий по поверхности корпуса конденсат сорбируетс тарелкой II, соединенной с отводным трубопроводом 6. Интенсификаци процесса охлаждени может достигатьс также вращением вокруг оси всего устройства .The hot air is trapped in the upper part of the sleeve by the fan 7 and supplied in the direction indicated by the arrows (see Fig. 1). With the passage of air inside the case, it is cooled and moistened with a spray of coolant. From the housing 2, the cooled air flow through the slit formed by the housing and the plate 11 is directed into the cavity between the ribbed outer surface of the housing and the film sleeve. When air moves in this cavity along wave-shaped channels 6 formed by ribs 12 on the outer surface of the body, a flow of air occurs, which intensifies the process of cooling the film. This is also facilitated by the intensive cooling of the casing from the inside by the flowing down layer of liquid. Intensive cooling of the housing contributes to the process of condensation of liquid vapors on the outer surface of the housing, thereby preventing the wetting of the inner surface of the film sleeve. The condensate flowing on the surface of the body is sorbed by the plate II connected to the branch pipe 6. Intensification of the cooling process can also be achieved by rotating around the axis of the entire device.
