In the present embodiment, upper cover 12 is tightly connected by vessel flange 11 and cylindrical shell 5.
In the present embodiment, the bottom of low head 2 is provided with skirt-type base 1; Between cylindrical shell 5, low head 2, be provided with liquid level gauge 3; Upper cover 12 is provided with relief valve port 13, hanger 14 and pressure detecting module 15.
The diameter 1300mm of the present embodiment middle cylinder body 5, built-in ripple packing 20 is divided into filtering accuracy 30 μ m perforated plate corrugated fillers and the each one deck of filtering accuracy 20 μ m screen waviness packings, and every layer of packed height is 100mm.Ripple packing 20 tops are filled with again multiple special round sheet doughnut filtrate 19, and filtrate diameter is 1300～1500mm, filtrate thickness 10～30mm.Bottom for filtering accuracy be 30 of the filtrates of 20 μ m, on it, loading successively filtering accuracy is 10 compositions of filtrate of 10 μ m, filter precision is 5 of the filtrates composition of 5 μ m and filters 1 of the filtrate that precision is 1 μ m topmost, and these doughnut filtrate 19 total heights are 400mm.Built-in 8 cyclone separators 7 in cylindrical shell 5, cyclone separator 7 key dimensions are diameter 200mm × height 1350mm.
The course of work of the present embodiment is as follows: first the gas that contains large quantity of fluid enter the space that upper spacer 22, lower clapboard 4 and cylindrical shell 5 form, now because gas flow rate reduces suddenly, in gas, large drop is because " gravitational settling " falls into above lower clapboard 4, these liquid that are captured are because the effect of gravity further enters by lower discharging tube 25 memory space that lower clapboard 4, cylindrical shell 5 and low head 2 form, when liquid collection (can show judgement by liquid level gauge 3) to a certain amount of time, can continue to flow out by liquid return hole 26 recycle.After long-term use, in liquid, have some solid impurities and deposit to low head 2 bottoms, now can regularly by sewage draining exit 31, solid impurity be discharged.The air inlet 36 that enters subsequently cyclone separator 7 containing liquid gas, gas tangentially enters shell 37 and produces High Rotation Speed, and now, due to the effect of centrifugal force, the drop that density is greater than to gas gets rid of to the wall of shell 37.Once drop contacts with the wall of shell 37, just lose inertia force and fall along wall by the momentum of entrance velocity and downward gravity, enter conical pipe 32 with whirlwind discharging tube 24 and be then discharged into the memory space that lower clapboard 4, cylindrical shell 5 and low head 2 form.High efficient low resistance cyclone separator can effectively separate for the drop being greater than more than 10 μ m, and for the drop separation effect meeting variation that is less than 10 μ m, these fine droplets finally can be taken out of cyclone separator 7 by air-flow.Fine droplets is taken out of after cyclone separator 7 by air-flow, gas passes through fixed-grid plate 21 and enters the bottom of filter box, pass through successively ripple packing 20 containing liquid gas, ripple packing 20 is mainly some stainless steel perforated plate corrugated fillers and screen waviness packings composition, its filtering accuracy also can be divided into several, adjacent two-layer ripple packing is staggeredly placed along ripple direction, the voidage of filler reduces from the bottom to top gradually, after ripple packing folding ripple, not only make effective filtration area increase, and due to crest, the effect of converging of the water conservancy diversion of trough more easily makes less drop form large drop.Air-flow is by after ripple packing 20 like this, larger drop is held back at the very large filler of the voidage of lower floor, and trapped at the closeer filler on upper strata compared with droplet, avoid in common filter most of droplet deposition on filter material surface, to make its resistance phenomenon rapidly that rises.This stainless steel ripple filler is not perishable simultaneously, and therefore the separating effect of ripple packing 20 is much better than common silk screen liquid knockout.After ripple packing 20 separates, still there are some tiny liquid fog particles in gas, gas enters the doughnut filtrate 19 on ripple packing 20 tops, doughnut filtrate 19 is round sheet structure, filtering accuracy progressively improves from the bottom to top, this structure, slightly large liquid fog particles is held back at the lower filtrate of lower floor's filtering accuracy, and less liquid fog particles is trapped at the higher filtrate of upper strata filtering accuracy, be that liquid fog particles is " solid " distribution in multilayer filtrate, this is different from all particles of filter cartridge type filter completely and is all trapped by filtrate " surface "; Simultaneously because special doughnut has " hollow " or " porous " structure, therefore also possesses " absorption " effect based on capillarity effect (being the surface tension of liquid) fiber, be specially adapted to the working condition that contains liquid fog particles in gas, the total arresting efficiency to liquid fog particles of this deep bed filter can be greater than 99.99%.After liquid in gas is efficiently trapped, clean gas is finally discharged by gas vent 16.The present embodiment is applied to domestic a certain cbm development and utilizes project, and coal bed gas consists of (volume ratio) CH
4=40%, air=60%, gas flow Q=6000Nm
3/ h, outlet pressure is 0.25MPaG, and outlet temperature T=65 DEG C has implemented the spray diesel oil type of cooling for ensureing that screw compressor system is normally moved, and the oil spout internal circulating load of helical-lobe compressor is up to W=36T/h.An original rearmounted separator reclaiming for diesel oil is wire packing separator, its diameter 1500mm, filtering accuracy 5 μ m, move after 24 hours and survey diesel oil race damage up to 1300kg, because diesel oil loss all too is large, a whole set of screw compressor system cannot normally be moved always.After the present embodiment puts into operation by application, move and after 24 hours, survey diesel oil and run damage and be less than 25kg, much smaller than the waste of original wire packing separator, met the manufacturing technique requirent of screw compressor system completely.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
