Abstract
The utility model provides an oilfield wastewater hardening breakthrough filter tank. The tank comprises a tank body (1), wherein a water inlet (2) is formed on the upper part of the tank body (1), and a water outlet (3) is formed on the lower part of the tank body (1); a filter layer (4) and a packing layer (5) are arranged in the tank body (1) from top to bottom; and a filter hardening breakthrough device (6) is arranged transversely above the filter layer (4), and comprises a plurality of steel plates (7) which are fixedly connected with the tank body (1). According to the oilfield wastewater hardening breakthrough filter tank, the hardening breakthrough device made of the plurality of steel plates is additionally arranged at the upper part of filter in the filter tank, so that the filter is lifted by backwashing water in a backwashing stage, and a large hardened filter can be cut and crushed by the steel plates when passing the steel plates, and the crushed filter is recovered to the state of original particles in the action of the backwashing water to restore the previous adhesion capability, so that the filter efficiency is improved.
Description
Technical field
The utility model relates to filtering tank, the broken filtering tank that hardens of particularly a kind of oilfield sewage.
Background technology
Along with deepening continuously of oil field development, crude oil water containing constantly rises, and oil extraction-generated waste water is handled the important process that has become waterflooding oil field.At present, adopt filtering tank more, sewage is filtered, oil or suspended impurity are adhered on the filtrate, thereby reach the purpose of sewage purification through filtrate for the processing of oilfield sewage.But this filtering tank is long service time one, will cause filtrate to harden because being stained with too many impurity on the filtrate, adheres to the ability drop of impurity, and filter efficiency reduces.At this moment, need carry out backwash, promptly intake from the delivery port of filtering tank below to filtering tank, the back flush filtrate, impurity is discharged from the water inlet of top.This kind method can be removed the impurity that adheres on the filtrate to a certain extent, if but run into the filtrate serious situation that hardens, the effect of this kind method is also unsatisfactory.Therefore, filtrate hardens becomes the most serious problem of filtering tank filter efficiency that influences, and needs a kind of oilfield sewage filtering tank that can prevent that filtrate from hardening of invention.
Summary of the invention
The purpose of the utility model has provided the broken filtering tank that hardens of a kind of oilfield sewage, solves existing filter material in oil field sewage filtering tank and hardens easily, the problem that causes filter efficiency to reduce.
The utility model is realized through following technical scheme: the broken filtering tank that hardens of oilfield sewage, comprise tank body, and tank body top has water inlet, and the bottom has delivery port; Filter material layer and padding layer are housed in the tank body from top to bottom; The broken device that hardens of filtrate laterally also is equipped with in described filter material layer top, and this device comprises the polylith steel plate that is fixedly connected with tank body.
Described steel plate is four, is cross arrangement.
Adopt the good effect of technique scheme: the utility model filtrate top in filtering tank installs the broken device of being processed by the polylith steel plate that hardens additional, and like this in the backwash stage, filtrate is by the backwashing water lifting; During through steel plate; The filtrate that hardens of bulk can under the effect of backwashing water, be pulverized and return to original graininess by the steel plate cutting and crushing simultaneously; Adhesive capacity before recovering improves filter efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 be among Fig. 1 A-A to vertical view.
Among the figure, 1 tank body, 2 water inlets, 3 delivery ports, 4 filter material layers, 5 padding layer, the broken device that hardens of 6 filtrates, 7 steel plates.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
Fig. 1 is the structural representation of the utility model, and is as shown in the figure, and the broken filtering tank that hardens of oilfield sewage comprises tank body 1, and tank body 1 top has water inlet 2, and the bottom has delivery port 3.Filtration stage, water inlet 2 is connected with water inlet pipe, and delivery port 3 is connected with outlet pipe; In the backwash stage, water inlet 2 is connected with outlet pipe, and delivery port 3 is connected with water inlet pipe.Filter material layer 4 and padding layer 5 are housed in the tank body 1 from top to bottom; Padding layer 5 mainly plays the effect of support; And filter material layer 4 is owing to have the less filtrate of particle; Thereby oil in the sewage and suspended impurity are adhered to, sewage is carried out filtering and impurity removing, the filtering accuracy of oilfield sewage is mainly decided by the granular size of filtrate.The broken device 6 that hardens of filtrate laterally also is equipped with in filter material layer 4 tops, and this device comprises the polylith steel plate 7 that is fixedly connected with tank body 1, and steel plate 7 can carry out cutting and crushing to the filtrate that hardens of bulk; Because the broken device 6 that hardens of filtrate is positioned at the filtrate top; So in the process of backwash, under the effect of backwashing water, the filtrate lifting; Through filter material is broken when hardening device 6, filtrate is cut fragmentation.
Fig. 2 be among Fig. 1 A-A to vertical view, as shown in the figure, too close if steel plate 7 is arranged, influence the filter tank maintenance, load filtrate; If steel plate 7, does not have the harden function of filtrate of due fragmentation again too in sparse.Take all factors into consideration the quantity of steel plate 7 in actual the use, steel plate 7 is set to four, be cross arrangement.
During use; At first water inlet 2 is connected with water inlet pipe, delivery port 3 is connected with outlet pipe, and oilfield sewage gets into tank body 1 from water inlet 2; When flowing through filter material layer 4; Oil in the sewage and suspended impurity are adsorbed by granular filtrate, and filtered sewage is discharged from delivery port 3, accomplishes filter process.After using a period of time, filter material layer 4 is owing to having adsorbed too many oil and the suspended impurity state that reaches capacity, and simultaneously, filtrate also forms hardening of bulk.At this moment, the filter efficiency of filter material layer 4 reduces greatly, need carry out backwash.Then water inlet 2 is connected with outlet pipe, delivery port 3 is connected with water inlet pipe, and clear water gets into from delivery port 3; The reverse cleaning; Filtrate is lifted under the effect of backwashing water, and the filtrate that hardens of bulk is being lifted to broken device 6 places of hardening of filtrate, can be by steel plate 7 cutting and crushings; Simultaneously under the souring of backwashing water, the graininess between the filtrate fragmentation reverted to.Backwash can be carried out sewage water filtration after accomplishing again, and the filter efficiency of filtrate can return to original state basically, prolongs the service life of filtering tank greatly, has also improved the index of filtered water.
