Abstract

The invention relates to devices for the formation of an aerosol of liquid supplied to a gas pipeline, and can be used in the gas and oil industries. The purpose of the invention is to increase the efficiency of the device. For this, the aerosol forming device is provided with a basket-shaped mesh element installed in the contactor, the upper end of which is located at the level of the lower edge of the nozzle. The mesh element serves as a gas distributing device and at the same time as a device preventing the coagulation of drops on the wall. This makes it possible to reduce the inhibitor iodine to the nozzles with the same removal from the contactor or to increase the mist flow from the contactor, which can improve the protection of the inner surface of the main gas pipeline or reduce the duration of the inhibitor supply to the gas pipeline during the interval during periodic cleaning. 1. il. § (L

ABOUT)

The invention relates to devices for generating an aerosol of liquid supplied to a gas pipeline, for example, for protection against internal corrosion or protection of gaskets against drying, and can be used in gas and oil concentrations.

The purpose of the invention is to increase the efficiency of the device. : The drawing shows the device, a general view.

I A device for forming aerosol 1 contains pressure gas pipeline 1, contact iTOp 2, pipes 3 and 4 for connecting | contactor 2 with pressure gas pipeline 1 And nozzle 5 located in contactor 2:: In addition, the device is equipped with a mesh basket-shaped element 6, upper tope-ipeu. which is located at the level of the bottom: the edge of the bottom 5.

gas pipeline 1, the remaining drops fall to the bottom of the basket, from which liquid flows out and collects in the lower part of contactor 2. Small drops falling on the inner surfaces of the mesh element 6 - the baskets rush upwards, picked up by gas coming through the slots of the mesh element 1 of 6. On the wall flow down, gradually penetrating outward, only large drops that do not form a fog. The speed in contactor 2 determines the size of the discharged mist particles, depends on the pressure drop in the pressure gas pipeline 1, the diameter of the pipeline 3 and the contactor 2, the resistance of the grid element 6 and other less significant causes and is calculated when designing the device.

The liquid accumulated in the lower part of the contactor 2, when the preset limit level is reached, is discharged through valve 9 connected by an electric or pneumatic 2 equipped with regulator 7, level 20 is matched to regulator 7 with regulator in weathering 10 in which occurs

fuy valve 9, connected electrically or pneumatically with regulators 7: level. The other end of the pipeline 8 when-; Connected to the weathering device 10 for the flare of the gas from the liquid. The gas is removed to the flare line 11, and the weathered liquid is pumped through pipelines 12 and 14, the passage filter 15, enters the

line 11. Pipeline 12 connection - 25 nozzle 5. Thus, liquid

;but also

: the weathering device 9 with E suction valve; pump panel 13, the exhaust valve of which is connected to the pipe 14, equipped with a filter 15. The pipe 14 is reinforced; flax in the wall of the contactor 2 and connected to the nozzle 5. Upper Part of the contactor 2 is connected by pipeline 4 to the pressure gas pipeline 1.

 The device works as follows:

; Part of the gas from the pressure gas pipeline 1 enters the pipeline 3 due to the pressure differential in the pressure gas pipeline 1 between the points of connection of pipelines 3 and 4. This gas through pipeline 3 enters the contactor 2, in which 30

circulates multiple times in a closed loop and only a part of it, which has low soar speeds, is spent in the pipeline in the form of a mist. The mist is transported through the pipeline, settling on its inner walls and creating a protective film. The selection of the geometrical dimensions of the supply pipeline and the contactor, as well as the pressure drop and the live section of the basket mesh element, allows for the necessary speeds.

Claims of Invention A device for forming an aerosol, a salt basket of a mesh element 6. Gas 40 holding a pressurized gas pipeline, a contactor. gas line 1, the remaining droplets fall to the bottom of the basket, from which liquid flows out and collects at the bottom of the contactor 2. Small droplets falling on the inner surfaces of the mesh element 6 — the baskets rush upward, picked up by the gas flowing through the slots of the mesh element 1ta 6. 6 Large droplets that do not form a fog flow down the wall, gradually penetrating outwards. The speed in contactor 2 determines the size of the discharged mist particles, depends on the pressure drop in the pressure gas pipeline 1, the diameter of the pipeline 3 and the contactor 2, the resistance of the grid element 6 and other less significant causes and is calculated when designing the device. The liquid accumulated in the lower part of the contactor 2, when it reaches the specified limit level, is discharged through the valve 9, which is connected electrically or pneumatically to the level regulator 7, to the weathering device 10, in which gas release from liquid. The gas is removed to the flare line 11, and the weathered liquid is pumped through pipelines 12 and 14, the passage filter 15, enters the nozzle 5. So m., liquid 0 five circulates multiple times in a closed loop and only a part of it, which has low soar speeds, is spent in the pipeline in the form of a mist.
