Background technology
The backwash regenerative process of traditional filter and filter process are antipodal two processes, the water inlet of filter process also is the delivery port of backwash process simultaneously, the delivery port of filter process is the water inlet of backwash process, the collection water distribution system of filter process is the collecting system of joining of backwash process, and the water (flow) direction of filter process is opposite fully with the water (flow) direction of backwash water inlet.
The backwash of conventional filter is achieved in that in the filter process when the effluent quality variation, or the filter inlet outlet pressure differential reaches certain value, or filtration time is when reaching certain value, system changes the backwash state over to, the press water that often provides by outside water pump or head-tank during backwash enters filter from filter bottom, make filter bed generation expansion to a certain degree by the backwash water distribution system again, the impurity and the oils of damming in filter bed are discharged from the backwash outlet.
There are following two problems in above-mentioned backwash filter: when 1, containing a spot of oils and sticky matter in coming water, these materials only are difficult to its separation by above-mentioned backwash process attached to the surface of particulate filter.2, when filtrate is light filter material, because the required requirement of strength of backwash, thereby very easily making filter bed produce excessive expansion causes opposite direction to filter phenomenon, and wash by rubbing with the hands not enough between the filtrate, the washability of filtrate is lower, impurity and oils in the filtrate are detained, and media regeneration is not thorough, thereby influences the effect of backwash.
Summary of the invention
The purpose of this utility model is to provide a kind of media regeneration that makes, and improves backwash effect, the fluidisation eddy flow back-flushing filtering device that the filtrate wash degree is high.
The technical solution adopted in the utility model: a kind of fluidisation eddy flow back-flushing filtering device, comprise filter cylinder and associated pipe, be provided with water collection sheet, filter bed, sparge pipe, water distribution tube in the cylindrical shell of filter cylinder, cylindrical shell is provided with water inlet manifold, total outlet pipe, be provided with eddy flow fluidisation device in the filter cylinder, eddy flow fluidisation device is communicated with the outer ejector of filter cylinder, and ejector is communicated with the hydraulic cyclone Scrubbing apparatus.Be provided with tapered distributor in the cylindrical shell.Eddy flow fluidisation device is arranged in the filter bed, and whirl cylinder is communicated with tangential water inlet pipe, is provided with the suction hose of band rectification head in the whirl cylinder, and suction hose is communicated with discharge nozzle.The filtrate of ejector goes out the filtrate inlet pipe that pipe is communicated with the hydraulic cyclone Scrubbing apparatus.The hydraulic cyclone Scrubbing apparatus is arranged in the water distribution tube at cylindrical shell top, washes the cylindrical shell top by rubbing with the hands and is provided with blow-off pipe.
The utility model has improved existing back-flushing filtering device, filter bed bottom at filter is provided with eddy flow fluidisation device, be provided with the hydraulic cyclone Scrubbing apparatus at the filter top, in the filter cylinder outer setting ejector is arranged, external press water makes filter bed produce the expansion of appropriateness by eddy flow fluidisation device and makes the particulate filter fluidisation of bottom, the ejector that is arranged on the filter outside produces negative pressure under external power hydraulic action, particulate filter after the fluidisation is aspirated and flows to the hydraulic cyclone Scrubbing apparatus that is arranged on the filter cylinder top, impurity on the filtrate and oils are cleaned in hydraulic cyclone Scrubbing apparatus cavity, and carry out Separation of Solid and Liquid, filtrate slides to the bottom by inwall, impure water goes out filter from hydraulic cyclone Scrubbing apparatus overhead stream, through above-mentioned filtrate backwash, make media regeneration, improve backwash effect, the utility model is simple in structure, be easy to make, filtrate wash degree height, economical and practical.Be applicable to the filter of filtering technique in the water treatment system.
