Description
The utility model relates to a kind of filter of handling oil-polluted water.
Handle in the engineering at oil-contaminated water of oil field, filter is indispensable purification of water quality treatment facility, and dual flow filter is more satisfactory filter.U.S. NATCO company produces the dual flow filter that uses and has characteristics such as rate of filtration height, good processed water quality, automaticity height, and this equipment mainly is used in the suspension of handling in the surface water and the underground water, is not suitable for handling oil-polluted water.The core texture of dual flow filter is a collecting system, collecting system adopts main pipe to cross filter middle portion, the chimney filter that catchments vertically is evenly distributed on the main pipe both sides, connect with main pipe, the chimney filter that catchments adopts common steel tube boring, outsourcing detailed catalogue polyester filter screen or detailed catalogue copper mesh, the pressure of both direction filtrate and water about the chimney filter that during normal use catchments will be subjected to, when backwash, to be subjected to the friction of the impact of backwash current and filtrate to filter screen, cause the distortion and the damage of filter screen, shorten the service life of filter screen, influenced the normal use of dual flow filter.In backwash process, filtrate is subjected to the impact of backwash current, and some filtrate is suspended in the water is drained, and causes filtrate to run off.In order to prevent that filtrate runs off, filter will be considered to increase by one section and give the section of staying when design, makes the filtrate buffering sedimentation that is suspended in the water, has increased the height of tank body, has increased the consumption of steel.
The purpose of this utility model provides a kind of oil-polluted water dual flow filter with new construction that overcomes above-mentioned deficiency.
The purpose of this utility model is to realize like this, a kind of oil-polluted water dual flow filter is by cylindrical shell (8), last skull (6), following skull (10), hand-hole (7), last water inlet pipe (4), divide water plate (5), following water inlet pipe group (11), central tube (9), peephole (2) constitutes, feature of the present utility model is: screen casing (15) adopts the V-type stainless steel wire to turn to tubular body twist in collecting system (1) member, interior edge reinforcement is made, screen casing (15) one ends spill closure plate (21) sealing, the other end is used greater than screen casing (15) diameter 6～10mm, the short circuit (22) of long 50～60mm is welded on the collecting system header (13).Screen casing (15) has the continuous slit of 0.4～0.7mm, the porosity height, and filtering material particle contacts with 2 of screen clothes, is difficult for blockedly, and this kind screen casing is corrosion-resistant, wear-resisting, mechanical strength is high, catchments evenly, advantage such as long service life.Go up skull (6) the inwall sand control device (3) that is coaxially set in last water inlet pipe (4) mouthful, filtrate runs off when preventing backwash, reduced simultaneously the sedimentation of filter buffering give the section of staying highly 20～30%.
Sand control device (3) is to become cylindrical framework by last angle ring (18), following angle ring (20), 4～8 angle steel columns (16) assembly welding, and the tubular body that interior laying one deck is turned to twist by the V-arrangement stainless steel wire is cut open and flattened end filter screen of making (19) and the wall filter screen (17) that rolls into.End filter screen (19), each contact site of wall filter screen (17) and garden cylindricality framework adopt brazing to be connected.The last angle ring (18) of sand control device (3) adopts sequential welding to connect with last skull (6) inwall contact site.
Description of drawings is as follows:
Accompanying drawing 1: oil-polluted water dual flow filter structural representation
Accompanying drawing 2:A-A profile
Accompanying drawing 3: screen construction figure
Accompanying drawing 4: sand control device structure chart
The utility model is described in further detail below in conjunction with accompanying drawing:
Accompanying drawing 2A-A profile has provided installation site, the structural plan figure of collecting system (1), and accompanying drawing 3 has provided screen casing (15) structure chart.Collecting system (1) adopts symmetric configuration central tube (9) lower step mode structure, can guarantee the uniformity that collecting system (1) is catchmented.In central tube (9) top attachment vertical symmetry distribution 4 headers that catchment (13) are arranged, other end cantilever or connect with tank skin, between the header that catchments (13), be furnished with 4 brace summers (14) symmetrically, one end connects with central tube (9), the other end connects with inner tank wall, at the same central plane of the header that catchments (13), filter symmetry according to different size is furnished with the screen casing that spacing is 250～350mm (15), screen casing (15) one ends connect with the header that catchments (13), and the other end connects with brace summer (14).Screen casing (15) by the V-arrangement stainless steel wire in the shape of a spiral shape turn to tubular body, an end is with spill closure plate (21) sealing, it is 50～60mm short circuit (22) welding that the other end is used greater than screen casing (15) diameter 6～10mm, length.
Accompanying drawing 4 has provided the detail of construction of sand control device (3), sand control device (3) is by last angle ring (18), following angle ring (20), middle by 4～8 angle steel columns (16), adopt welding to be connected into cylindrical framework, in be equipped with the V-arrangement stainless steel wire and turn to tubular body twist and cut open and flatten end filter screen (19), the wall filter screen (17) make, adopt brazing to connect with cylindrical framework contact site.Sand control device (3) is gone up angle ring (18) and is welded in skull (6) inwall with the tank body coaxial line.
The utility model compared with prior art, the advantage that has is:
1, adopted V-arrangement stainless steel wire coiling spiral screen pipe to have continuous slit, the porosity height; 2 contacts of filtrate are difficult for blocked; Have corrosion-resistant, wear-resisting, the advantages such as mechanical strength is high, catchment even, long service life.
2, because sand control device has been installed, prevented that the filtrate that causes runs off when backwash, reduced the sedimentation of tank body buffering and given 20～30% of the section of staying height.
