In the present embodiment, the diameter of cylindrical shell 5 is 1400mm, fixed-grid distribution grid 19 is provided with a filter box, more filter box also can be set in addition as required, the height of each filter box is 100～600mm, doughnut filtrate 10 is at each filter box all in appropriate impaction state, and the diameter of filter fiber disk is 1400～1600mm, the thickness 30mm of filter fiber disk.The filtrate 40 slices that filtering accuracy is 20 μ m has been filled in filter box bottom, on it, loading successively filtering accuracy is 20 compositions of filtrate of 10 μ m, filter precision is 10 of the filtrates composition of 5 μ m and filters 1 of the filtrate that precision is 1 μ m topmost, the total height of this filter box is 600mm, built-in 12 cyclone separators 7 of the present embodiment, cyclone separator 7 key dimensions are diameter 240mm × height 1765mm.
The present embodiment operation principle be: first the gas that contains liquid and solid particle polluter enter upper spacer 20 from air inlet 6, in the intracavity space that lower clapboard 4 and cylindrical shell 5 form, now because gas flow rate reduces suddenly, oarse-grained liquid and solid particle polluter in gas (as particles more than 100 μ m) are because " gravitational settling " falls into the upper surface of lower clapboard 4, these impurity that are captured are because the effect of gravity further enters lower clapboard 4 by lower discharging tube 22, the memory space that cylindrical shell 5 and low head 2 form, store and (can show judgement by liquid level gauge 3) a certain amount of time and by sewage draining exit 28, impurity is discharged when impurity.Gas enters the annular region of tubular shell 31 with the outlet 33 of cyclone separator 7 subsequently, gas is High Rotation Speed under the guide functions of axial-flow type high-speed swirl vane 32, now due to the effect of centrifugal force, the impurity particle that density is greater than to gas gets rid of to the wall of tubular shell 31, once impurity particle contacts with the wall of tubular shell 31, just lose inertia force and fall along the internal face of tubular shell 31 by the momentum of entrance velocity and downward gravity, enter Taper Pipe 29 and be then discharged into lower clapboard 4, the memory space that cylindrical shell 5 and low head 2 form, cyclone separator 7 can effectively separate for the impurity particle being greater than more than 10 μ m, for the impurity particle separating effect meeting variation that is less than 10 μ m, these fine impurity particles finally can be taken out of cyclone separator 7 by air-flow.Fine impurity particle is taken out of after cyclone separator 7 by air-flow, gas passes through fixed-grid distribution grid 19 and enters the bottom of filter box, in filter box, be filled with the doughnut filtrate 10 of round sheet structure, filtering accuracy progressively improves from the bottom to top, this structure makes larger impurity particle be held back at the lower filtrate of lower floor's filtering accuracy, and less impurity particle is trapped at the higher filtrate of upper strata filtering accuracy, be that impurity particle is " solid " distribution in filter box, this is different from all impurity 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 also contain in gas the working condition of a small amount of liquid impurity (as tar and water etc.), the total arresting efficiency to impurity particles such as dust of this deep bed filter can be greater than 99.99%.Tens of extremely hundreds of tailor-made fibre filtrates that impurity particle in dusty gas is filtered in casing efficiently trap, and clean gas is finally discharged by gas vent 16.The biological marsh gas power generation of domestic certain industrial methane company one develops project, contains saturated mode water, tar and a small amount of solid dust in biogas, and biogas consists of (volume ratio) CH

3/ h, for the drag overall of the normal service requirement compressor of assurance system pre-separator is less than 3000Pa.This biogas enters screw rod booster compressor after double-filtration separator, due to gaseous impurity complicated component and there is corrosivity, screw rod booster compressor row access cycle is only 1～2 day, screw rod booster compressor is taken the rear mixture of finding to have in cavity a large amount of thick black liquors and solid of maintenance apart, original double-filtration separator is that a diameter 1600mm roughing efficiency air filter (efficiently imitate filter (filtering accuracy 10 μ m) by filtering accuracy 50 μ m) the diameter 1800mm that connects, actual motion approximately after 7 hours the drag overall of double-filtration separator be greater than 3000Pa, the maintenance of high frequent ground and the excessive resistance of double-filtration separator are perplexing the progress of whole project always.After application the present embodiment, approximately discharge the about 65kg of mixture of muddy black liquor and solid every day from sewage draining exit 28, screw rod booster compressor row access cycle extends to seven months, and whole biogas generating develops project operation stability and obviously strengthens, and has met manufacturing technique requirent.
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.
