Abstract

The utility model relates to a sewage treatment plant, in particular to an integrated oil removing settling filter with high precision which can simultaneously realize the oil-water separation and the solid-liquid separation. A tank is sequentially divided into a buffering chamber (2), a coarse granulation chamber (3), the sloped-tube oil-removing chamber (4), a water collecting chamber (5), a flow guiding tube (10), the flocculating chamber (7) of the swirling flow reaction, the sloped-tube settling chamber (8), and the filter chamber (9) of the filtering core from the sealing head end of the tank body by a separator plate. A static mixer (12) is connected out the tank body, and an oil drain port is arranged on the top of the tank body. A soil discharging port (17) is arranged on the bottom of the tank body. The whole integrated oil removing settling filter adopts the horizontal tubular structure, and has the advantages that volume is small; the functions are full; the movable components do not have; the operation is simple; the operation is safe.

Description

Comprehensive oil removing sedimentation strainer

Affiliated technical field: the utility model relates to a kind of waste disposal plant, particularly can realize the comprehensive oil removing sedimentation of the high precision strainer of oily water separation and solid-liquid separation simultaneously.

Background technology: existing equipment is that water treatment agents such as flocculation agent, coagulant aids are added before processing, and experiment shows that it is not fine processing efficient like this, and the medicament service efficiency is low, and the medicament add-on is also very big, is unfavorable for running cost control.Its two be equipment coarse material selection be haydite or the floating filter material of the about 3mm of diameter, the coarse void ratio that is made of the solid filtrate of this class small particle size is only about 50%, has the susceptible to plugging defective of filtering layer.Three what be that the equipment filtering unit adopts is walnut shell filtering material, quartz sand or fibrous nodules even-granular filtrate for it, this type of filter type all can not the better controlled final outflow water in the particle diameter of suspended solids, and rejection of oil flied effluent has higher requirements to this, especially low permeability oil field.

Summary of the invention: the purpose of this utility model is a kind of comprehensive oil removing sedimentation strainer of design, makes its crude oil when oily water separation and solid-liquid separation, reaches to add that medicament is few, processing efficiency is high, save cost, effect of settling, wash nonclogging purpose easily.

The purpose of this utility model is to realize like this, comprehensive oil removing sedimentation strainer, it is characterized in that: tank body is divided into buffer chamber, coarse chamber, inclined tube oil removal plant, the chamber that catchments, thrust-augmenting nozzle by dividing plate from the seal head end order, cyclone reaction flocculating chamber, inclined plate sedimentation device, filter element filtering chamber; Tank body connects static mixer outward, is provided with oil discharge outlet at the cylindrical shell top; In the cylindrical shell bottom mud discharging mouth is arranged.

The filter element filtering chamber comprises " O " type sealing filter core that is made of non-woven fabrics.

Described coarse chamber selects for use the multiaspect hollow ball as the coarse material.

The utility model is selected hydrophilic non-woven fabrics filter core for use, can be changed the filter core of different size according to the effluent quality requirement easily, and " O " type of filter core employing simultaneously sealing plug-in card is fixed, easy accessibility.

The utility model complete machine adopts horizontal tubular structure, has that volume is little, function is complete, no dynamic component, characteristics simple to operate, safe and reliable to operation, is the ideal equipment of handling oilfield sewage, and the while can be widely used in the oily water treatment of other industry.

The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:

Description of drawings: Fig. 1 is the utility model example structure synoptic diagram;

Among the figure: 1, pipeline; 2, surge chamber; 3, coarse chamber; 4, inclined tube removes the grease chamber; 5, the chamber that catchments; 6, reaction chamber; 7, cyclone reaction flocculating chamber; 8, inclined tube settling pocket; 9, filter element filtering chamber; 10, thrust-augmenting nozzle; 11, dosing mouth; 12, static mixer; 13, diffusing opening; 14, filter core; 15, oil discharge outlet; 16, oil extraction; 17, mud discharging mouth; 18, water outlet.

Embodiment: as shown in Figure 1, oily(waste)water arrives surge chamber 2 by pipeline 1 after entering horizontal garden tube container, float to the equipment top here in the water on the oil slick, current enter coarse chamber 3 from the bottom, select for use the multiaspect hollow ball as the coarse material, current are by passing down in the process of coarse layer, the little oil droplet of dispersive contacts with the coarse material impacts in the water, caught by oil loving coarse material surface and assemble, when oil reservoir gathers to a certain degree, oil droplet breaks away from multiaspect hollow ball surface under buoyancy and sluicing, particle diameter become big oil droplet be easy to arrive equipment top oil reservoir, enter inclined tube with current and remove the oil droplet of grease chamber 4 by further come-up removal, 2,3, total oil removal efficiency about 80% of 4 three steps; The water that catchments in the chamber 5 is drawn by thrust-augmenting nozzle 10, and diversion pipeline is provided with dosing mouth 11, and flocculation agent is added by dosing mouth 11; Tangentially enter reaction chamber 6 after 12 pressures mix with water through static mixer then, current are the eddy flow attitude to prolong current through line in reaction chamber, guarantee the reaction times, then enter flocculating settling chamber 7 by diffusing opening 13, current are laminar flow regime in this chamber, be beneficial to the formation and the sedimentation of flocs unit, in inclined tube settling pocket 8 subsequently, little flocs unit is by further sedimentation removal, the suspended solids and the oil in water emulsion of removing that do not floated are caught by flocs unit in this process in the former water, select suitably by 6 as medicament, 7, suspended substance is all removed basically in the 8 three step water; The filtering chamber 9 that is located at the equipment end can do accurately control to effluent quality according to user's requirement, be not more than 1 micron as suspended solids particle diameter in the low permeability oil field requirement water outlet, then equipment is joined 1 micron filter core 14 and is got final product, filter core 14 selects for use hydrophilic to be beneficial to clean, " O type " sealing-ring card insert type connects, the convenient installation and replacing; Handle water footpath, back water outlet 18 remover apparatus at last;

The oil slick that is gathered in each chamber roof is discharged from oil discharge outlet 15 by control draining valve 16; The heavy body refuse that combines in device bottom is discharged by mud discharging mouth 17; For the benefit of the spoil disposal washpipe can be established in the soil discharging facility bottom.
