Description

The utility model relates to the field of gas purification from drops of various liquid media and can be used in the chemical, petrochemical and oil and gas industries.

There is a separator for drying gas, which contains a housing with nozzles for inlet of raw gas, outlet for purified gas and liquid outlet and inlet and outlet filter sections located in the housing (RF patent No. 2147914, IPC B01D 45/12, 04/27/2000).

The disadvantage of this apparatus is the low efficiency of its operation at a relatively low flow rate, since the continuity of the fluid flow is disrupted, and gas flows through the drain pipes from the bottom up. This disrupts fluid drainage, which reduces cleaning efficiency.

Also known apparatus, consisting of a housing with nozzles for the inlet of the gas mixture, the outlet of gas and liquid, separation elements mounted on a plate equipped with a drain pipe, the end of which is connected to the tank for collecting liquid. In such a separator, the liquid is drained from the cavity of the plate equipped with separation elements through a pipe lowered into the liquid located in the liquid collector (RF patent No. 2056135, IPC B01D 45/12, 03/20/1996).

The disadvantage of this separator is the unreliability of its operation in the presence of solid particles in the gas being cleaned, as well as with a low content of the liquid phase in it. The presence of solid particles leads to clogging of the drain pipe, and with a low content of the liquid phase, gas may break through the drain pipe and disrupt the water seal, which reduces the cleaning efficiency.

The closest technical solution to the claimed utility model is a separator for drying gas, comprising a housing with nozzles for inlet of raw gas, outlet for purified gas and liquid outlet and inlet and outlet filter nets located in the housing (RF patent No. 2252813, IPC B01D 45/12, 53 / 26, 01/19/2004).

The disadvantage of this separator is the possibility of secondary entrainment of droplets with dried gas, since the outlet pipe of the dried gas is located at the top of the column.

The objective of the utility model is to provide high efficiency gas purification from drip moisture.

This utility model provides high efficiency of gas purification from drip moisture due to equalization of gas flow by a guiding grid having a resistance coefficient ξ from 4.9 to 5.9, enlargement of liquid droplets in a packed layer consisting of irregular nozzles “Inzhekhim-2000” ( Certificate of the Russian Federation for utility model No. 13950, B01F 5/00, 06/20/2000), the deposition of liquid droplets on the inner side of the tube walls due to centrifugal force (at a gas velocity W _g greater than 30 m / s) caused by a tape swirler.

Thus, the technical result is achieved due to the fact that in the separator for drying gases from drip moisture, consisting of a housing with nozzles for the inlet of the initial gas-liquid mixture, the outlet for gas purified from moisture and the outlet for the separated liquid phase, according to the claimed utility model, an inner pipe is additionally introduced and a mesh demister located around the perimeter between the inner pipe and the casing, while in the inner pipe there is a guide grid with a resistance coefficient ξ from 4.9 to 5.9, section irregular metal nozzle made in the form of nozzles "Inzhekhim-2000", and a plate on which the tube with tape swirler.

The essence of the utility model is illustrated by the drawing, which shows the inventive separator for drying gases from drip moisture.

The numbers in the drawing indicate:

1 - inner pipe

2 - housing

3 - pipe inlet of the original gas-liquid mixture,

4 - guide grid,

5 - section irregular metal nozzles made in the form of nozzles "Inzhekhim-2000",

6 - tubes with a tape swirler,

7 - outlet pipe of the separated liquid phase,

8 - mesh demister,

9 - outlet pipe purified from moisture gas,

10 - a plate.

The separator for gas drying from drip moisture consists of a housing 2 with nozzles 3, 7, 9, respectively, of the inlet of the initial gas-liquid mixture, the outlet of the gas purified from moisture and the outlet of the separated liquid phase. The difference between the inventive separator is that the inner pipe 1 and the mesh demister 8 are additionally introduced into the separator. In the inner pipe 1, a guide grid 4, section 5 of irregular metal nozzles and a plate 10 are arranged sequentially. On the plate 10 there are tubes 6 with a tape swirler. The mesh demister 8 is located around the perimeter between the inner pipe 1 and the housing 2 at an angle of 45 ° and consists of a fine mesh laid in a bag.

The guide grid 4 is a permeable transverse partition of a metal sheet with holes. The resistance coefficient of the guiding grid ξ is from 4.9 to 5.9, as a result of which there is no flow circulation zone behind the grid 4. As section 5 contact devices, Inzhekhim-2000 irregular metal nozzles are used.

The separator for drying gases from a drop of moisture works as follows.

The initial gas-liquid mixture enters the separator inner tube 1 through the nozzle 3. Next, the mixture, bypassing the guide grid 4, where the flow is equalized, enters section 5 of the irregular metal nozzles, where the liquid droplets coarsen. After section 5 of the irregular metal nozzles "Inzhemim-2000", the mixture passes through tubes 6 with a tape swirler. The liquid phase is deposited on the inner side of the walls of the tubes 6 due to centrifugal force (at a gas velocity W _g greater than 30 m / s) caused by the tape swirler, and flows into the lower part of the separator under the action of gravity. Through the pipe 7, the separated liquid leaves the separator. The purified gas through a mesh demister 8, which prevents secondary entrainment of the liquid phase, leaves the inner pipe 1 and leaves the separator through the pipe 9.

The use of this utility model in the chemical, petrochemical and oil and gas industries, where gas purification from the liquid phase is required, will ensure the efficiency of gas purification, for droplets greater than 5 microns, not less than 99%.
