Problems solved by technology

However, in the process of filtration and separation, due to the fact that the dust in the natural gas is easily broken under the action of pressure difference, and the stainless steel wire trap is deformable, the small particle size dust is easy to penetrate the filter rod under the action of pressure difference. The separation effect of the device on small particle size dust needs to be further improved
At the same time, because the filter rod is installed horizontally, the sewage discharge and backwashing of the separator are not smooth, which may easily cause the separated dust to block and bury the filter rod, thereby further reducing its separation efficiency.

Embodiment Construction

[0019] Further illustrate the present invention below in conjunction with accompanying drawing.

[0020] Referring to Fig. 1, the vertical cyclone filter dust collector is mainly composed of a separator shell 7, a filter rod 3, a filter screen 5 wound on the filter rod, etc. It is characterized in that the filter rod 3 has an opening 4, And the number of openings is sparse on the top and dense on the bottom, its upper end is connected with the separator exhaust port 2, and its lower end is sealed, and a helical guide vane 6 with variable pitch is installed on the filter rod, and the pitch gradually becomes smaller from top to bottom, so There is a certain gap between the spiral guide vane 6 and the inner wall of the separator shell 7, and a sewage outlet 9 is also provided at the bottom of the separator.

[0021] Installing the broken rotary plate 8 at the lower part of the dust collector can effectively prevent the natural gas from continuing to swirl after passing through th...

Abstract

A cyclone filter type vertical duster for separating water and dust from natural gas has a separator casing, a filter rod and a filter net wound on said filter rod. It features that the perforated filter rod has a top end communicated to the exhaust outlet of separator and a sealed lower end, a spiral guide blade wigh a gap between it and casing is installed to said filter rod, and said separator has a bottom blowoff.

Description

technical field [0001] The invention relates to a natural gas deduster in the field of oil and natural gas production, and a deduster for purifying dusty gas. technical background [0002] In the process of natural gas production and pipeline transportation, due to stratum, pipe wall corrosion and abrasion, etc., natural gas often contains a certain amount of water and dust, which brings great harm to the safe production of natural gas. [0003] In order to remove water and dust contained in natural gas, separators and dust collectors of different structures have been produced. There are mainly vertical gravity gas-liquid separators and horizontal gravity gas-liquid separators for natural gas dehydration, multi-tube dry dust collectors for dry gas dust removal, and wet dust collectors for wet gas dust removal. Dust removal cyclone separator, filter separator, and spiral separator, circulation separator, etc. developed on the basis of cyclone separator. The application of t...
