The utility model content
The utility model is intended to overcome above-mentioned the deficiencies in the prior art, provides a kind of country that can reach to the water quality requirement of oil field oil recovery re-injection water and filter core are difficult for stopping up, service life is long sewage fine filter.
The sewage fine filter that provides according to the utility model, comprise water inlet pipe and outlet pipe, be provided with first between described water inlet pipe and the outlet pipe, the second two fine filtering jars, described water inlet pipe is provided with sewage pump, the water inlet of the described first fine filtering jar communicates with water inlet pipe, the delivery port that described first fine filtering is irritated communicates by first pipeline with the water inlet of the second fine filtering jar, the delivery port of the described second fine filtering jar communicates with described outlet pipe, the filter core of the described first fine filtering jar is thick titanium filter core, and the filter core of the described second fine filtering jar is thin titanium filter core.
The utility model also has following additional technical feature:
The filtering accuracy of described thick titanium filter core is 10um, the filtering accuracy 0.5um of described thin titanium filter core.
Be provided with backwash clear water jar, the delivery port of this backwash clear water jar communicates with second pipeline, the end of described second pipeline communicates with first pipeline and outlet pipe by the 3rd pipeline and the 4th pipeline respectively, described water inlet pipe is provided with first blow-off pipe that is communicated with it, described first pipeline is provided with second blow-off pipe that is communicated with it, described second pipeline is provided with recoil pump, and described the 3rd pipeline, the 4th pipeline, first blow-off pipe, second blow-off pipe are provided with valve.
The switching of described valve, recoil pump, sewage pump are controlled by a control device.
The sewage fine filter that provides according to the utility model, prior art has following advantage relatively: 1, the utility model adopts two-stage thickness titanium filter core fine filtering jar, this structure makes filter back water quality reach the water quality requirement of country for re-injection water, and filter core is difficult for stopping up.2, adopt titanium filter core, filter membrane heatproof (filter membrane operating temperature-200～800
, corrosion-resistant, antipollution, fouling, resistance to compression, strong shock resistance, long service life, the replacement cycle was generally 5 years, and it is strong that anti-water quantity and quality changes impact capacity, stable water outlet.3, the switching of described valve, recoil pump, sewage pump are controlled by a control device, and its automaticity is higher, and is easy to operate.
Description of drawings
Embodiment below in conjunction with accompanying drawing provides describes the utility model in detail, wherein:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the schematic top plan view of Fig. 1.
The specific embodiment
Referring to Fig. 1 and Fig. 2, a kind of optimal way of sewage fine filter of the present utility model is shown, comprise water inlet pipe 1 and outlet pipe 2, be provided with first between described water inlet pipe and the outlet pipe 2, the second two fine filtering jars 3,4, described water inlet pipe is provided with sewage pump 6, the water inlet of the described first fine filtering jar 3 communicates with water inlet pipe, the delivery port of described first fine filtering filling 3 communicates by first pipeline 5 with the water inlet of the second fine filtering jar, the delivery port of the described second fine filtering jar communicates with described outlet pipe, the filter core 30 of the described first fine filtering jar is thick titanium filter core, the filter core 40 of the described second fine filtering jar is thin titanium filter core, the filtering accuracy of described thick titanium filter core is 10um, the filtering accuracy 0.5um of described thin titanium filter core, this structure makes filter back water quality reach the water quality requirement of country for re-injection water, and filter core is difficult for stopping up.
Moreover, titanium filter core filter membrane heatproof (filter membrane operating temperature-200～8 ℃), corrosion-resistant, antipollution, fouling, resistance to compression, strong shock resistance, long service life, the replacement cycle was generally 5 years, and it is strong that anti-water quantity and quality changes impact capacity, stable water outlet.Each titanium filter core has two fibrages of thickness, and the crude fibre layer has higher mechanical strength, at the peripheral backing material of forming of filter core; Fine fiber layer is then main filtration in inside, can prevent that particle from penetrating filter medium, avoids the obstruction of titanium metal film, and the concrete structure of filter core itself is applicant's patent applied for, no longer describes in detail here.
Be provided with backwash clear water jar 7, the delivery port of this backwash clear water jar 7 communicates with second pipeline 70, the end of described second pipeline communicates with first pipeline 5 and outlet pipe by the 3rd pipeline 73 and the 4th pipeline 74 respectively, described water inlet pipe is provided with first blow-off pipe 71 that is communicated with it, described first pipeline is provided with second blow-off pipe 72 that is communicated with it, described second pipeline is provided with recoil pump 75, and described the 3rd pipeline, the 4th pipeline, first blow-off pipe, second blow-off pipe are provided with valve 76.The switching of described valve, recoil pump, sewage pump are subjected to a control device 8 controls, and its automaticity is higher, and is easy to operate.
