Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, the present invention includes whirl cylinder 2 and structure of filtering layer 9;
Described whirl cylinder 2 is provided with gas feed and gas vent, described gas feed is arranged on the top of whirl cylinder 2 sidewall, whirl cylinder 2 is the tubular of rotary body, gas feed is preferably arranged along the tangent line of whirl cylinder 2, gas, entering into after in whirl cylinder 2, can be rotated down leading of whirl cylinder 2 inwall;
Described structure of filtering layer 9 is tubular and is arranged in whirl cylinder 2, the sidewall spacers certain distance of structure of filtering layer 9 and whirl cylinder 2, namely between the two every setting, whirl cylinder 2 is divided into two spaces by described structure of filtering layer 9, and two spaces are eddy flow space between structure of filtering layer 9 and whirl cylinder 2 sidewall and the filtration space being positioned at structure of filtering layer 9 respectively; As shown in Figure 2, it is set in whirl cylinder 2 structure of structure of filtering layer 9, is rotary body tubular, and the upper end open of structure of filtering layer 9 also seals the top being arranged on whirl cylinder 2;
Described gas vent is connected with filtration space, and described gas feed is connected with eddy flow space.
In use, the gas feed of this device is connected with the upstream and downstream of instrumentation pipeline respectively with gas vent, impure natural gas enters in whirl cylinder 2 through gas feed, natural gas along with whirl cylinder 2 inward eddy Space Rotating, large granular impurity heavier in natural gas, part water and bubble the separated bottom depositing to whirl cylinder 2 of discharge opeing; Then natural gas is from 360 degree through structure of filtering layer 9, and namely natural gas can pass from the whole perisporium of filtering layer, and particulate contaminant, bubble discharge opeing and water are all filtered, and finally pure natural gas enters gas vent and discharges from filtration space.
In said apparatus, whirl cylinder 2 not only makes natural gas rotating separation, natural gas can also be made from 360 degree through structure of filtering layer 9, this not only reduces the filtration yield of structure of filtering layer 9, structure of filtering layer 9 can also be made to be fully played, even if this device volume is less, also have stronger filter capacity and larger filter area.
