    1502504 Degassing liquids RHONEPOULENC INDUSTRIES 7 Nov 1975 [8 Nov 1974] 46241/75 Heading B1M Apparatus for the separation of a heterogeneous mixture including a continuous liquid phase of higher density than the other phase of the mixture comprises a jacket 1; a weir 3 extending upwardly into said jacket and defining a continuous space, between said jacket and the weir forming a decantation zone, said weir having an upper rim; at least one outlet 4 for liquid in the jacket connected to the space at a location below the upper rim of the weir, at least one outlet 5 for the other phase in the jacket at a location above the upper rim of said weir; and at least one obstacle 6 located in the decantation zone above the first outlet effective to tend to equalise the vertical component of the local speed of overflow along the length of the rim of the weir. As shown, the obstacle presents its greatest obstruction immediately above the outlet 4, and tapers off so as to present no obstruction diametrically opposite that point.

    The invention relates to chemical. This technology, the economic community and its adjacent areas can be used for gas separation operations from the continuous liquid phase, as well as for separating inclusions of light liquids from heavy ones.
    Known devices for processing. Liquid by gas, in which the liquid continuously flows vertically from bottom to top, while this gas phase is dispersed in the liquid phase. In the upper part of such column type devices, the maximum possible separation of a heterogeneous gas-liquid mixture or separation of gases and liquids to a predetermined degree 11 and 2 is provided.
    The apparatus most commonly used for such separation is formed by a vertical cylinder (casing) whose diameter exceeds the diameter of the coaxially mounted inlet pipe, which is the upper part of the column. The upper part of the inlet pipe is installed inside the separation unit, the lower part of which is equipped with one or more continuous exhaust channels. liquid phase. To output separated
    The gas phase serves as an outlet channel at the top of the device. The gas phase separation occurs when the gas-liquid mixture moves 180 degrees at the outlet of the inlet pipe and continues as the fluid moves further down the annular precipitation zone formed by the casing and the inlet pipe to the outlet channel. However, when moving down to the discharge channel, the continuous liquid phase entrains gas bubbles, which can separate if their lifting speed exceeds the vertical component of the local speed of the downward movement of the gas-liquid mixture.
    This disadvantage can be eliminated in devices by using a SUCTION zone located in a casing of larger diameter, which, however, entails a significant increase in the dimensions of the device.

    The closest to the described invention to the technical essence and the achieved result is a centrifugal separator, which serves to separate the heterogeneous gas-liquid mixture consisting of gas and liquid droplets 3. A special feature of this device is the presence as an additional resistance on the outlet pipe of concentrically arranged annular obstacles of bumpers having a profile device constant in the cross-sectional plane. The purpose of the strikers in the device is to increase the efficiency of separation of the dispersed phase from the continuous continuous one. However, the use of this type of dummies with a constant profile in the non-specified separation devices with a vertical inlet pipe of the annular deposition zone and exhaust channels does not provide sufficient device performance while achieving the proper separation of the dispersed gas Phase due to the presence of gas capture by the liquid taken into the exhaust channel. The aim of the invention is to increase the separation efficiency of the gas-liquid mixture and increase the recovery of the continuous liquid phase by reducing the entrainment of gas by the liquid. This goal is achieved by the fact that, in the device, the visor Ilyuete has a variable profile in the cross section of the device and is installed in the deposition zone eccentrically relative to the inlet pipe with a maximum section located above the outlet channel to remove the liquid phase. Fig, shows the proposed device, the cut; 2 - section A-A of FIG. 1. The device consists of a vertical cylindrical housing 1, the diameter of which is larger than the diameter of the inlet pipe 2, at the base of the annular deposition zone 3, the device is equipped with an outlet channel 4 for taking a continuous liquid phase. To deduce the divided gas phase, the channel 5s serves as a fender visor b with a profile variable in the plane of the cross section of the device, the horizontal RS dimension of which continuously changes from one end to the diametrically opposite end, fixed in the annular deposition zone perpendicular to the axis of the device on the outer wall of the inlet pipe, eccentrically relative to it and with placing a maximum cross section above the outlet channel to remove the liquid phase. The device works in the following way. The initial heterogeneous gas-liquid mixture is continuously supplied from the bottom upwards through the inlet pipe, where it undergoes a change in direction by 180, with a part of the gas mixture flying to the free surface of the mixture 7. Then the separation of the mixture occurs during downward movement in the annular precipitation zone. The fender visor variable profile creates in the zone of deposition of pressure loss, the maximum in the area above the outlet channel of the liquid phase. Thus, it is possible to maintain the vertical component of the local discharge rate less than the rate of rise of gas bubbles, which continue their upward movement from the deposition zone to the free surface of the mixture, while the degassed liquid phase is continuously withdrawn through the discharge channel. The inlet pipe can be equipped with a truncated cone in the upper part, preventing a vortex from occurring on the outer surface of the wall of the inlet pipe, reducing the free cross section for the passage of fluid to the lower part of the annular sedimentation zone and causing an increase in the local discharge rate, which leads to an increased entrainment of the gas phase with the liquid As a result of experimental studies of the device according to the invention (casing diameter 800 mm, diameter of the inlet pipe 715 mm, position of the discharge channel of the liquid phase s 450 mm below the top of the inlet pipe, the position of the upper level of the mixture in the device n. 250 mm above the upper edge of the intake pipe), it was found that replacing the permanent profile fender in it with the fender visor of the variable profile allows for the same separation effect the gas phase from the liquid to increase the capacity of the device in the liquid phase from 130 to 185. The use of the device according to the invention allows to increase by 50% the position of the mixture level. The proposed device for separating a heterogeneous gas-liquid mixture allows to significantly increase the efficiency of separation of the gas-liquid mixture and to increase the selection of the continuous liquid phase. Claims of the Invention A device for separating a heterogeneous gas-liquid mixture, the predominant phase of which is a liquid containing a housing, an inlet pipe located coaxially with the housing, in the annular space between which a precipitation zone is installed and an exhaust duct installed in it to remove separated LIQUID and gas phase. characterized in that, in order to increase the separation efficiency of the gas-liquid mixture and increase the extraction of the continuous liquid phase by reducing the entrainment of gas by liquid, the fender visor has a variable profile in the plane of the device’s cross-section and is eccentrically positioned relative to the inlet pipe with a maximum section above the exhaust channel for removing the liquid phase.
