Separation elements are made in the form of longitudinal plates at the ends with channels, and in the cavity of the separator - with T-shaped partitions. The side walls have L-shaped and T-shaped partitions. In the cavity of the separator there are transverse H-shaped partitions 12 rigidly fixed on the lid of the device, equipped with flat central flow dividers 13. The dimensions of all partitions and channels are made in multiples of 1/2 of the width of the input (output) channels, while channel, T-shaped and H-shaped partitions mutually overlap each other by the same amount. 6 hp f-ly, 4 ill.

Description

The invention relates to devices for separating a dropping liquid from a gas-liquid stream and can be used in all areas of the industry associated with cleaning a gas from a dropping liquid by precipitating it under the action of inertial forces and changing the direction of motion.

The aim of the invention is to increase the efficiency of droplet separation by eliminating secondary liquid entrainment.

FIG. 1 shows a separator, a general view; FIG. 2 shows section A-A in FIG. one; in fig. 3 - half separator with beveled corners at the reflector at the inlet of the gas-liquid flow; in fig. 4 - the same, with the splitters with the apex directed to the flow. The horizontal separator comprises a housing 1 with side walls 2, a crush 1, a tray 3 with a drain pipe 5. The side walls 2 are provided with an end at the inlet and outlet with reflective L-shaped partitions 6 and T-shaped along the geometric axis of symmetry from the inside - partitions 7. The separator cavity is provided with longitudinal plates 8, from the ends of which channel-channel reflectors 9 are attached at the inlet and outlet, and according to symmetry axes on both sides of the plates 8 - T-shaped partitions 10.

The side walls 2 and the longitudinal plates 8 in the lower part are rigidly attached to the edge of the pallet 4, and in the upper part are detachable in the grooves 11 of the cover 3 of the device body 1.

In the cavity of the separator there are H-shaped transverse partitions 12 provided with flat central dividers 13 of the flow rigidly attached to the roof 3 of the housing 1.

The half separator can be made with beveled corners 14 (Fig. 3), as well as with flow dividers 15 (Fig. 4). The flow inlet constructions are applicable to the full separator variant.

Longitudinal plates 8, provided with face and axial reflective partitions, side walls 2 with reflective face and axial partitions, in combination with transverse partitions 12, with a mutual arrangement, form input 16 and output 17 channels, a system of direct channels 18, rotary 19 and around 5

 20 movement of the gas flow with multiple changes in the direction of movement of the gas-liquid and gas flow by 180. In this case, all partitions and reflectors of the device mutually overlap each other by an amount equal to half the width of the input and output channels. The width of the passage Q channels between the partitions is equal to the same value.

The separator works in the following way.

The horizontal gas-liquid flow through the inlet channels 16 enters the transverse partitions 12, the flow is separated by flat dividers 13 while simultaneously changing the direction of the flow by 180 °, thus there is a primary separation of the large fraction of the liquid phase flowing into the tray 4 along the walls of the transverse partitions 12. Passing the rotary channel 19, the gas-liquid flow enters the channel 20

the reverse movement of the flow, in the turning channel 49, changes the direction of movement by 180, is again released from the coarse fraction of the liquid phase and follows into the channel 18 of the direct movement of gases. Upon a subsequent turn at 180, the passage of the reverse movement channel 20 and the turn following this turn at 180. the flow is completely freed from the coarse fraction of the liquid phase. The gas-liquid stream, released from the coarse fraction of the liquid phase, enters the subsequent forward movement channel 18, and the cycle repeats again.

Further repetition of the cycle ensures complete separation of the fine fraction of the liquid phase and gas; released from the liquid phase, leaves the device through the outlets 17.

With a reduced content of the fine fraction of the liquid phase, a half sepsfator (Fig. 3 or 4) is used to ensure complete gas purification.

Channel, T-shaped and H-shaped partitions, which overlap each other by 1/2 the width of the input (output) channel, provide a constant cross section for the passage of gases.

 55 To improve the drain of the separated liquid, the separator can be set at an angle of 2–3 to the direction of the gas-liquid flow.
