Description

FIELD OF TECHNOLOGY

The inventive utility model relates to filter separators and is intended for the purification of gas-air mixtures from mechanical impurities, aerosols of water and oil. The most effectively claimed utility model can be used in gas transmission systems to remove mechanical impurities and moisture from natural gas.

Known filter separator for cleaning gas and liquid fuel from moisture and mechanical impurities, protected by UA patent for utility model No. 5544, class MKI V01D 25/00, publ. 03/15/2005. The filter separator consists of a vertically oriented cylindrical body equipped with a cover, inlet and outlet pipes, a drainage system and a filter element. The filter element is made in the form of a hollow cylinder mounted in a housing with an annular gap. The inlet pipe is located in the bottom of the housing and communicates with the inner cavity of the filter element, and the outlet pipe is on the side surface of the housing in its upper part.

The disadvantage of this filter design is to limit its scope. A filter of this design cannot be effectively used in gas transmission systems operating under high pressure and at high gas flow rates. With these

conditions when the gas is supplied to the inner surface of the filter element, its structure may be disturbed or it may even be completely destroyed.

Known filter separator for cleaning gas-air mixtures from mechanical impurities, aerosols of water and oil, protected by UA patent for utility model No. 13319, class MKI V01D 25/00. Such a filter withstands high gas pressure and at the same time provides effective cleaning of gas from moisture in the form of aerosols, oils and mechanical impurities. But if the gas contains a large amount of droplet liquid and large mechanical impurities, then special separators must be installed in front of the filter, capable of cleaning the gas-liquid mixture from both liquid and mechanical impurities (see descriptions of inventions to copyright certificate SU No. 1492522 and patents RU No. 2147914, No. 2290984). Such separators act as the first (coarse) stage of natural gas purification.

Thus, with the current level of technology for effective gas purification in order to prevent the failure of instrumentation and automation, which modern gas transportation is mandatory, it is necessary to install in series devices for coarse and fine purification of natural gas.

DISCLOSURE OF THE USEFUL MODEL

The claimed utility model is based on the task of creating a filter separator that combines the functions of both coarse and fine purification of natural gas.

The closest in technical essence to the claimed utility model is a filter separator according to patent UA No. 13319, IPC V01D 25/00, publ. 03/15/2006.

A disadvantage of the known filter separator is that it cannot be used when cleaning heavily soiled

gas-liquid flows, i.e. its scope is limited.

Common features of the claimed filter separator and filter separator according to the prototype are:

- the implementation of the filter separator in the form of a vertically oriented cylindrical body;

- placement in the housing of the filter separator of the filter element;

- the implementation of the filter element in the form of a hollow cylinder installed in the housing with an annular gap;

- supplying the housing with a removable cover, inlet and outlet pipes and drainage system;

- the location of the inlet pipe in the lower part of the housing on its side surface;

- placement of the outlet pipe below the lower level of the filter element;

- the installation of a filter element at an elbow transition connecting the outlet pipe to the internal cavity of the filter element.

The technical task is to expand the field of use of the known filter separator.

The problem is solved due to the fact that in the known filter-separator, consisting of a vertically oriented cylindrical body, inside which a filter element is installed with an annular gap, made in the form of a hollow cylinder, equipped with a removable cover, an inlet pipe located in the lower part of the housing on its side the surface and the outlet pipe, which is located below the lower level of the filter element and communicates with the internal cavity of the filter element through a cranked transition, in accordance with the proposed utility model

- the filter separator body is divided into upper and lower chambers by a partition installed at the level of the inlet pipe and inclined downward;

- a central hole is made in the partition;

- a cylindrical glass adjoins from below to a partition;

The glass together with the partition acts as a swirl of the incoming gas stream, contributing to the release of mechanical impurities and large drops of liquid from the gas stream, and the partition, in addition, prevents the entry of "dirty" gas into the upper chamber, designed for fine gas purification.

To enhance the effect of swirl on the glass outside, swirl vanes can be installed on the outside of its bottom.

To exclude the possibility of gas “trapping” contaminants emitted from it as a result of swirling the stream, a cone-reflector of purified gas can be installed at a certain distance from it, with its vertex pointing upward.

BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1 shows the design of the proposed filter separator.

The filter separator for gas purification consists of a housing 1, equipped with a removable cover 2 and a bottom 3, a tangential inlet pipe 4 and an outlet pipe 5. Inside the housing 1, a filter element 6 is installed, the inner cavity of which is connected to the outlet pipe 5 using an elbow transition 7. The partition 8 divides the housing 1 of the filter separator into the upper and lower chambers. In the lower chamber, a glass 9 adjoins the partition 8, provided with swirl blades 10. Under the glass 9, at a certain distance from it, there is a cone 11 facing upward. In the bottom of the filter separator there is a drainage pipe 13 and a valve for draining the liquid 12.

WORK DESCRIPTION

The filter separator operates as follows.

Natural gas, moist, contaminated air, or any gas-liquid mixture enters the filter separator through the tangential inlet 4. When entering the apparatus due to the impact of the flow on the glass 9 and due to the swirling flow around the glass 9, the largest drops and free liquid, as well as mechanical impurities discarded to the walls of the housing 1 and flow into the bottom 3 of the housing 1. Removal of liquid and mechanical impurities is carried out through the drainage pipe 12 and the drain valve 12 .. Gas partially purified from liquid and mechanical pollution, is reflected from the cone 11 and rushes into the upper chamber. Passing through the filter element 6, the gas is freed from moisture residues and possible smallest mechanical impurities, and through the crankshaft 7 and the outlet 5 are removed from the apparatus.

INDUSTRIAL APPLICABILITY

The use of a utility model in gas transmission systems can increase the efficiency of natural gas separation while reducing production costs by expanding the range of use of filter separators by combining coarse and fine purification of natural gas in one apparatus.
