Description

Изобретение относится к сепаратору для отделения жидкости от газа и может быть использовано в любых отраслях народного хозяйства.The invention relates to a separator for separating liquid from gas and can be used in any sectors of the economy.

Наиболее близким к предлагаемому, является сепаратор для отделения жидкости от газа, включающий корпус с патрубками для подвода газожидкостной смеси и отвода разделенных фаз и ротор И·Closest to the proposed one is a separator for separating liquid from gas, including a housing with nozzles for supplying a gas-liquid mixture and for removing the separated phases and a rotor And

Ротор состоит из дисков, соединенных ₍обечайкой, и лопаток, а средний диск, установленный между соединенными обе• чайкой дисками, образует сообщающиеся камеры.The rotor consists of disks connected _{(by a} shell, and blades), and the middle disk, installed between the disks connected by both gulls, • forms interconnected chambers.

Однако в данной конструкции отделение жидкости от газа происходит недостаточно хорошо, так как при подаче смеси последняя может попасть как на ротор, так и в корпус сепаратора без ее разделения, и далее пройти в канал для отвода газа.However, in this design, the separation of the liquid from the gas is not good enough, since when the mixture is supplied, the latter can enter both the rotor and the separator body without separation, and then pass into the gas exhaust channel.

Цель изобретения - предотвращение попадания жидкой фазы в патрубок для отвода газа и обеспечение надежности работы сепаратора.The purpose of the invention is to prevent the liquid phase from entering the nozzle for exhaust gas and ensuring the reliability of the separator.

Для достижения поставленной цели в предложенном сепараторе ротор выполнен в виде диска, имеющего наружный и внутренний кольцевые выступы, расположенные концентрично, причем внутренний кольцевой выступ образует камеру для отвода газа, а в кольцевой полости, ограниченной внутренним и наружным выступами, расположена динамическая прокладка. Выступы имеют отверстия для прохода газа в камеру его отвода, а к наружному кольцевому выступу ротора радиально прикреплены лопатки с образованием отсеков в корпусе для разделения газожидкостной смеси.To achieve this goal in the proposed separator, the rotor is made in the form of a disk having an outer and inner annular protrusions arranged concentrically, the inner annular protrusion forming a chamber for exhausting gas, and a dynamic gasket is located in the annular cavity bounded by the inner and outer protrusions. The protrusions have openings for the passage of gas into its exhaust chamber, and blades are radially attached to the outer annular protrusion of the rotor to form compartments in the housing for separating the gas-liquid mixture.

На фиг. 1 схематично ихображен сепаратор, общий вид; на фиг. 2 - сечение А-А на фиг, 1.In FIG. 1 schematically shows a separator, general view; in FIG. 2 - section aa in FIG. 1.

Сепаратор содержит корпус 1, в котором размещен ротор 2 в вице диска, установленного на валу 3 и имеющего наружный 4 и внутренний 5 кольцевые выступы, расположенные концентрично, причем внутренний кольцевой выступ 5 образует камеру 6 для отвода газа, а в кольцевой полости, ограниченной внутренним 5 и наружным 4 выступами, расположена динамическая прокладка 7, удерживаемая штифтами 8.The separator includes a housing 1, in which the rotor 2 is placed in the vice of the disk mounted on the shaft 3 and having an outer 4 and an inner 5 annular protrusions arranged concentrically, the inner annular protrusion 5 forming a chamber 6 for venting gas, and in the annular cavity bounded by an inner 5 and the outer 4 protrusions, there is a dynamic gasket 7, held by pins 8.

Выступы имеют отверстия 9 для прохода газа в камеру 6 его отвода, а к наружному кольцевому выступу 4 ротора 2 радиально прикреплены лопатки 10 с образованием отсеков 11 в корпусе 1 для разделения газожидкостной смеси.The protrusions have openings 9 for the passage of gas into the chamber 6 of its outlet, and blades 10 are radially attached to the outer annular protrusion 4 of the rotor 2 to form compartments 11 in the housing 1 for separating the gas-liquid mixture.

Сепаратор работает следующим образом.The separator works as follows.

По питающему патрубку 12 газожидкостная смесь поступает в отсеки 11 вращающегося ротора 2, откуда лопатками 10 отбрасывается по кольцевой образующей корпуса 1. При этом газ, как более легкая фаза, под действием центробежной силы, цо мере выделения из жидкости проходит динамическую прокладку 7 через отверстия 9 и поступает в камеру 6 для его отвода через патрубок 13.Through the supply pipe 12, the gas-liquid mixture enters the compartments 11 of the rotating rotor 2, from where the blades 10 are discarded along the annular generatrix of the housing 1. In this case, the gas, as a lighter phase, under the action of centrifugal force, passes through the openings 7 through the openings 9 through the openings 9 and enters the chamber 6 for its removal through the pipe 13.

При вращении ротора. 2 создается центробежная сила, деформирующая динамическую прокладку 7, за счет чего перекрывается зазор 14, образованный между ротором 2 и крышкой 15. Поскольку динамическая прокладка 7 выполнена из стружки полимерного материала, последняя свободно пропускает, воздух и препятствует прохождению жидкости через зазор 14 во время отсоса воздуха через патрубок 13.When the rotor rotates. 2, a centrifugal force is created that deforms the dynamic gasket 7, due to which the gap 14 formed between the rotor 2 and the cover 15 is closed. Since the dynamic gasket 7 is made of shavings of polymer material, the latter freely passes air and prevents the passage of liquid through the gap 14 during suction air through the pipe 13.

Отделившаяся жидкость отводится из сепаратора через патрубок 16, а дляThe separated liquid is discharged from the separator through the pipe 16, and for

820889 4 предотвращения попадания атмосферного воздуха в случае прерывистой подачи смеси предусмотрен обратный клапан 17 в патрубке 16.820889 4 to prevent the ingress of atmospheric air in case of intermittent supply of the mixture, a check valve 17 is provided in the pipe 16.

₅ Предлагаемая конструкция сепаратора обеспечивает более полное отделение жидкости от воздуха и более надежную его работу. _{5 The} proposed design of the separator provides a more complete separation of the liquid from the air and its more reliable operation.

Claims

The invention relates to a separator for separating liquid from gas and can be used in any industry in which it is used. The closest to the proposed one is a separator for separating liquid from gas, including a housing with patches for supplying a gas-liquid mixture and withdrawing separated phases and a rotor 1. The rotor consists of disks connected by a tank and blades, and an average disk mounted between the connected shell discs form communicating chambers. However, in this construction, the separation of the liquid from the rasa does not take place well enough, since when the mixture is supplied, the latter can get into both the rotor and the separator body without separating it, and then pass into the gas exhaust channel. The purpose of the invention is to prevent the liquid phase from entering the gas outlet and to ensure that the separator operates at the highest level. In order to achieve this goal, in the downstream separator, the rotor is made in the form of a disk having outer and inner annular protrusions arranged concentrically, with the inner annular protrusion forming a gas exhaust chamber, and in the annular cavity bounded by the inner and outer protrusions a dynamic lining is located. The projections have openings for the passage of gas into the chamber of its outlet, and the blades are radially attached to the outer annular protrusion of the rotor with the formation of compartments in the housing to separate the gas-liquid mixture. FIG. 1 schematically depicts a separator, a general view; in fig. 2 is a section A-A in FIG. 1. The separator includes a housing 1 in which a rotor 2 is disposed in the form of a disk mounted on a shaft) 3 and having an outer 4 and an inner 5 annular protrusions arranged concentrically, the inner annular protrusion 5 forming a chamber 6 to exhaust gas, and in the annular cavity bounded by the inner 5 and outer 4 protrusions, there is a gasket 7 held by pins 8. The protrusions have openings 9 for the passage of gas into the chamber 6 of its outlet, and to the outer annular protrusion 4 of the rotor 2 attached blades yus the formation of compartments 11 in the housing 1 of the OLE of the separation of the gas-liquid mixture. The separator works as follows. Through the feed nozzle 12, the gas-liquid mixture enters the compartments 11 of the rotating rotor 2, from where blades 1O are thrown along the ring forming body 1. At the same time, the gas, as a lighter phase, under the action of centrifugal force, dynamically separates from the liquid 7 through the holes 9 and enters the chamber 6 to discharge it through the nipple 13. When the rotor is inserted. 2, a centrifugal force is created that deforms the dynamic gasket 7, thereby closing the gap 14 formed between the rotor 2 and the lid 15. Since the dynamic gasket 7 is made of polymeric material chips, the latter freely passes through the air and prevents the liquid from passing through the gap 14 during the suction of air through the nozzle 13. The separated liquid is removed from the separator through the nozzle 16, and a check valve 1 is provided to prevent the ingress of atmospheric air in the event of an intermittent mixture supply. 7 in the pipe 16. The proposed design of the separator provides a more complete separation of the liquid from the air and its more reliable operation.
