Description of drawings

Fig. 1 is an example structure figure of the present utility model.

Fig. 2 is the cutaway view of Fig. 1.

The specific embodiment

In Fig. 1, Fig. 2, cylindrical shell 1 is a cylindrical shape, be fixed on the base 21, knot screen chamber 32, air flue chamber 29, the, the dirty chamber 24,23 of second collection in 1 chamber of cylindrical shell, have been separated out, described drain 31 and liquid level gauge 12 and relief valve connection 8 are arranged on respectively on the cylindrical shell 1 corresponding to knot screen chamber 32, promptly communicate with knot screen chamber 32 respectively, the position, bottom, nearly chamber in intake interface 30 and knot screen chamber 32 communicates, the big right gas introducing knot screen chamber 32 that will be needed removal of impurities, be removed drop by intake interface 30.Interface of the level gauge 28 has a pair of, continue respectively on cylindrical shell 1 corresponding to air flue chamber 29 and the dirty chamber 23 of second collection, liquid level gauge 12 also has a pair of, one of them continues on the cylindrical shell 1 corresponding to 32 nearly middle parts, knot screen chamber, and another then continues on the cylindrical shell 1 corresponding to 32 nearly bottoms, knot screen chamber.Sewage draining exit 19,22 collects dirty chamber 24,23 with first, second respectively and communicates.Continue on the cylindrical shell 1 corresponding to first collection 24 tops, dirty chamber in gas outlet 15, and corresponding to de-watering apparatus.Cover 3 can open and close to be configured in the top of cylindrical shell 1, and its unlatching or close by fast opening and closing device 2 and take on is consistent with in one's power structure in the Chinese patent application numbers 200520076728.9 about the concrete structure of fast opening and closing device 2 and function.

Still see Fig. 1, Fig. 2, the quantity that constitutes one group of filtering core device of knot screen of the present utility model is not to be subjected to concrete the qualification, and for example when the plot ratio of cylindrical shell 1 was big, knot screen chamber 32 was also big so, therefore the quantity of the filtering core device of being arranged in knot screen chamber 32 is just many, and vice versa.Tube cavity wall by base dividing plate 14 and cylindrical shell 1 fixes and is separated out knot screen chamber 32, and the filter tube 11 of crossing of each filtering core device is vertically fixed on the base dividing plate 13, and the tube chamber of crossing filter tube 11 should communicate with air flue chamber 29.Filter cartridge seat 9 is fixed on the bottom of filter element fixed bar 7, and preferably is that the filter element 6 that material constituted is arranged on the body of rod of filter element fixed bar 7 with the yarn.In order to make filter element 6 on filter element fixed bar 7, embody the good effect that is provided with, therefore at the top of filter element 6 by filter element pressing plate 5 and add nut 4 and give spacing.When contain assorted and the natural gas that contains hydrone after intake interface 30 is incorporated into knot screen chamber 32, because this chamber is to separate mutually with the air flue chamber 29 of its below by cylinder base dividing plate 13, therefore gas can only filter after the passage 10 on the filter cartridge seat 9 entered into the tube chamber of filter tube 11 through filter element 6, enters into air flue chamber 29 by the tube chamber of crossing filter tube 11 again.

Cooperate base dividing plate 13 to be separated out air flue chamber 29 by median septum 27, upper spacer 14, in air flue chamber 29, de-watering apparatus is set, because the setting of de-watering apparatus, therefore, be incorporated into gas the air flue chamber 29 from the tube chamber of crossing filter tube 11, just can enter the dirty chamber 24 of first collection after can only removing drop in the gas by de-watering apparatus, and then draw by the import 15 of giving vent to anger that turns on first collection 24 tops, dirty chamber.See that by figure first, second collects between the dirty chamber 24,23 and separates by lower clapboard 20.

The de-watering apparatus of recommending as the utility model is made of one group of waveform filter disc 17, constitute drainage trap 18 on each piece waveform filter disc 17, and constitute air flue 16 between the adjacent waveform filter disc 17, the upper support of waveform filter disc 17 is on the bottom surface of upper spacer 14, and lower support is on the water filtration disc 26 of band lower flume 25.By above-mentioned narration as can be known, de-watering apparatus belongs to vane type separator category, and it can separate the drop that is mixed in combustion gas or the water vapour effectively.Because its effect height, pressure drop are low, and only need maintenance seldom.Material for the waveform filter disc 17 that plays guide functions can be a carbon steel, also can be stainless steel, also can be stainless steel or aluminium or the like.When gas during by air flue chamber 29 tying-in waveform filter discs 17, can be divided into many vertical banded streams by the waveform filter disc, each strand gas is all through repeatedly changing direction, so just, on the sheet wall of waveform filter disc 17, half turbulent flow and eddy flow have been produced, make the drop that is mixed in the gas be forced to hit on the sheet wall and above sticking to, drop enters in the drainage trap 18 and because of the gravity effect and drops in the water filtration disc 26 of taking on the liquid header effect, and then enters the dirty chamber 23 of first collection.

Gas enters the dirty chamber 24 of second collection through de-watering apparatus, and then by drawing corresponding to the interface 15 of giving vent to anger on second collection 24 tops, dirty chamber, in this process, still have the trace drop then can drop to second the collection dirty chamber 24 below, when reaching a certain amount of, then can be by opening valve on the blowdown interface 19 with its discharge or final the utilization.

The applicant sketches application of the present utility model in conjunction with Fig. 1, Fig. 2, and the natural gas that is used for separating and filtering is incorporated into knot screen chamber 32 from intake interface 30, and the cover 3 of this moment should be closed, and blowdown import 19,22 is also closed.The fluid level condition of natural gas in knot screen chamber 32 can be examined by the liquid level gauge on the interface of the level gauge 12 and know.Because the natural gas that enters into knot screen chamber 32 is through i.e. one group of filter element 6 filtration of a set filter, to separate greater than particulate 100% ground of 3 μ m by filter element 6, fall 99.5% for the particulate of 0.5-3 μ m is separable, therefore, has good impurity-eliminating effect, passage 10 on the natural gas via filter cartridge seat 9 after the removal of impurities entered filter tube 11, drew and air flue chamber 29.Owing to be provided with de-watering apparatus in the air flue chamber 29, so natural gas can only just be able to earlier be drawn by the interface 15 of giving vent to anger behind one group of waveform filter disc 17, specifically can help to understand by the arrow on signal representative natural gas flow way in the drawings.Through the effect of one group of waveform filter disc 17, can separate greater than drop 100% ground of 8-10 μ m, fall 99.5% for the drop of 0.5-8 μ m is separable, therefore, have the excellent effect of removing the drop in the natural gas.The capacity condition of natural gas in air flue chamber 29 can be examined by the liquid level gauge on one of them interface in a pair of interface of the level gauge 28 and know, in like manner, the dirty amount situation of collection in the dirty chamber 23 of second collection can be by interior liquid level gauge reflection on another interface of the level gauge 28, when reaching a certain amount of, got rid of as long as open sewage draining exit 22 so, the drop in the dirty chamber 24 of first collection is got rid of by sewage draining exit 19.After use after a while, can look concrete condition filter element 6 is changed.
