Description
Technical field
The utility model relates to a kind of filter plant, and especially the oil-polluted water multilayer is mixed the filtering material filter automatic flushing device.
Background technology
At present, secondary oil recovery and tertiary phase have successively been arrived in China oil field, and oilfield produced waste water complicated component, corrosivity be big, it is very big to contain poly-condensed oil sewage, intractability.The filter of China's present some models in oil field, great role has been played in sewage disposal at that time, but the requirement to existing sewage disposal technology level can not be satisfied, major technology is improved three aspects: one uses measures such as mechanical agitation, two big flow hydraulic reverse flushings, three air backwashes to carry out media regeneration, for preventing phenomenons such as filtrate knot plate, caking, the dead filter tank of paste.By the operation of long period, prove and take effect all not quite that mechanical agitation backwash power consumption is big, fault is many.Big flow hydraulic reverse washing water quantity is big, flushing cycle short, and filtrate runs off serious, existing patented technology, and the air backwash is polluted filtrate and is difficult to a wash clean, has increased in the air oxygen to the corrosive power of filter tank and miscellaneous equipment.For strengthening antiseptic power, a lot of oil fields are used natural gas or nitrogen wash instead, have strengthened operating cost, problems such as antiseptic property difference.
The utility model content
In order to overcome the deficiency that existing filtering tank exists, the utility model provides a kind of novel oil-polluted water multilayer to mix the filtering material filter automatic flushing device.It is unclean that it has solved the greasy dirt flushing that filter material surface adheres in the existing sewage backwash device, and filtrate runs off seriously, ties the problem of plate, caking.
The technical scheme that its technical problem that solves the utility model adopts is: the oil-polluted water multilayer is mixed the filtering material filter automatic flushing device, it is at the filtration tank body sewage recycling can be arranged on one side, its top has the pipeline of bringing flowing water Valve into to be connected with filtration tank body top, filtering the tank body middle upper part has the flushing flexible pipe, and elevating mechanism is arranged below successively, filter import, the anti-net that loses of filtrate, porous disc, the filtrate syringe, the composite filtering material layer, the filtrate separation net, porous disc, the filtrate syringe, the composite filtering material layer, the filtrate separation net, the filter screen syringe, porous disc, the filtering outlet that picks out, there is the tank body base bottom; Filter the tank body right side manhole, flange are arranged successively, filter the tank body another side water pump and filter back clear water jar are arranged, there is the pipeline of bringing flowing water Valve into to link to each other on the water pump with last flushing flexible pipe, the pipeline left side has the pipeline of bringing flowing water Valve, flange into to link to each other with the filter screen syringe, and the water pump right side has the pipeline of bringing flowing water Valve into to link to each other with filter back clear water jar.
Operation principle:
When filtering tank washes, filtered water is passed in and out valve all close, again flushing water valve and flowing water Valve to be opened, the filtrate syringe washes from top to bottom, when movable syringe goes downwards to the end, washes a few minutes.Close filter screen syringe valve, syringe begins up, is up to the top flushing process and finishes.The oil of filter material surface, suspension, polymer are rinsed totally.The up discharge of sewage, filter bed regeneration.Close the flushing inlet valve, flowing water Valve is opened filtered water turnover valve and is begun to filter.
The beneficial effects of the utility model are that the oil-polluted water multilayer is mixed the filtering material filter automatic flushing device, effectively filter material surface is adhered to the dirt flushing and separates and discharge, flushing power 7.5KW, flush water pump flow 100m
3/ n, flushing cycle is long, can rise to 72 hours, and it is low to have a power consumption, and water consumption is little, and flushing cycle is long, efficient is high, media regeneration is good, do not run material, filter back crystal's degree advantages of higher.
