Natural gas multilevel filtering mechanism

Abstract

The invention discloses a natural gas multilevel filtering mechanism. The natural gas multilevel filtering mechanism comprises a filter element and a main case, wherein the filter element comprises aninner filtering supporting sleeve and an outer sleeve, the bottom surface of the main case is fixedly connected with a bottom cover by virtue of a bolt, the bottom surface of the bottom cover is fixedly provided with lower supporting legs, and the bottom ends of the lower supporting legs are fixedly provided with a horizontal bottom plate; two circulation holes are formed in the middle part of the bottom cover, the bottom surface of the middle part of the bottom cover is fixedly provided with a feeding pipe and a discharging pipe, the end parts of the feeding pipe and the discharging pipe arerespectively communicated with the corresponding circulation holes, a side air inlet hole is formed in the lower side wall of the main case, the side air inlet hole is communicated with a vertical air guide through hole formed inside a side plate of the main case, and the vertical air guide through hole is communicated with a transverse air guide through hole formed in the middle part of a top plate of the main case. The natural gas is filtered by the filter element, enters from the side air inlet hole and passes the vertical air guide through hole and the transverse air guide through hole, so that the liquid in the filtered natural gas can be further separated from the gas under the effect of the gravity, and the filter separation effect is further improved.

Description

Technical field: [0001] The invention relates to the technical field of natural gas and petroleum equipment, and more specifically relates to a natural gas multi-stage filtering mechanism. Background technique: [0002] When natural gas is processed, it needs to separate the liquid from the gas. In the existing equipment, the filter element is used to filter, and the filter only needs to be filtered once, the effect is limited, and the filter is not thorough; [0003] Moreover, when the existing filter element is installed in the housing, it is generally fixed by bolts, which is troublesome to fix, and it is also inconvenient to install and disassemble. At the same time, the filter element in the existing filter device is generally a porous sleeve. Fix the glass fiber layer on the top to filter. It generally needs to be cleaned or replaced after a period of use. Since the glass fiber layer and the porous sleeve are fixed directly, it cannot be disassembled and separated, and...

[0002] When natural gas is processed, it needs to separate the liquid from the gas. In the existing equipment, the filter element is used to filter, and the filter only needs to be filtered once, the effect is limited, and the filter is not thorough;

[0003] Moreover, when the existing filter element is installed in the housing, it is generally fixed by bolts, which is troublesome to fix, and it is also inconvenient to install and disassemble. At the same time, the filter element in the existing filter device is generally a porous sleeve. Fix the glass fiber layer on the top to filter. It generally needs to be cleaned or replaced after a period of use. Since the glass fiber layer and the porous sleeve are fixed directly, it cannot be disassembled and separated, and cleaning is troublesome, and generally does not need to be cleaned. It just makes it necessary to replace after cleaning once or twice, and the service life is short
