Description
Technical field
The utility model relates to a kind of waste disposal plant.Being particularly related in the petroleum industry oil-gas field surface engineering technology, handling the device of oily(waste)water, specifically is a kind of sewage to be carried out coagulation, coalescent, oily water treatment device that sepn process is brought together.
Background technology
Along with the development that deepens continuously of petroleum natural gas exploration, the oily(waste)water amount that produces in the production process is increasing, and the oily(waste)water composition is also complicated, makes oily water treatment face many new problems.Wherein distinct issues are exactly that oily water treatment efficient is low the most, and technical process is long, investment and running cost height.Contain a large amount of pollutents in the oily(waste)water, wherein be mainly chemical agent that adds in mineral oils, heavy metal ion, suspended substance and the crude production process that is not removed in the oil water separation process etc.Adopt traditional oil-containing sewage treatment technique and existing installation, handle oily(waste)water, can not satisfy outer standard of drainage.
The gordian technique of oil-gas field produced water disposal is the small oil droplet (mainly referring to emulsification shape oil droplet) that is dispersed in the water, is gathered into larger particles and separates from water rapidly.Both at home and abroad the oil-contaminated water of oil field treatment process is a lot, and gravity separation, coalescent, flotation, filtration method etc. are arranged.Be mainly used in petroleum-type and the suspended substance removed in the sewage.At present, China generally adopts oil removing, two sections flow processs of filtration to remove petroleum-type and suspended substance in the sewage.Oil removal plant is efficient in order to make, miniaturization, prefabricated, because domestic oil-contaminated water of oil field composition complexity, it is not ideal enough to add that homemade chemical agent mixes, and falls flat.Usually need to add a large amount of medicaments or the like, the whole bag of tricks all exists certain shortcoming and defect.Therefore, develop that organic pollutant degradation technology efficiently, added amount of chemical are little, running cost and cost of investment is low, technical process is short novel oilfield recovered water standard discharge and utilize one of problem of the technology person's current research that is the environmental scientific research again, also be oil field efforts at environmental protection urgent problems.In traditional apparatus for treating sewage, coagulation, coalescent, separation is to carry out in different equipment, exists equipment many in actual applications, long flow path, occupation of land is many, problems such as oil removal efficiency difference.
The utility model content
The purpose of this utility model provides a kind of multifunctional oil-contained waste water treater, reaches to realize airtight oil removing, efficient height; Compact construction is saved and is taken up an area of.Therefore, we have researched and developed the multifunctional oil-contained waste water treater that integrates three kinds of functions.
The technical scheme in the invention for solving the technical problem is:
The multifunctional oil-contained waste water treater is in horizontal pressure vessel, and the difference in functionality district of coagulation district, coalescent district and disengaging zone is arranged, and finishes coagulation, coalescent and isolating whole process respectively, thereby reaches the simplification flow process, reduces the purpose of taking up an area of.
Multifunctional oil-contained waste water preparation implement body structure is in horizontal pressure vessel, and the oily(waste)water end that enters the mouth is the coagulation district, and there is the eddy current flocculator in the coagulation district.Oily(waste)water mixes by eddy current flocculator eddy current, guarantees that oily(waste)water enters before the coalescent district, adds medicament and oily(waste)water thorough mixing, more helps small oil droplet and fully flocculates.
Coalescent pack has been installed in coalescent district.According to the coalescence material difference, adopt different fixed forms to be fixed on the pressurized vessel inwall.When for example adopting the stainless steel coalescence material, because the stainless steel coalescence material is the lumphy structure of rule, thus after the stainless steel coalescence material neatly discharged, the stainless steel coalescence material is fixed on the pressurized vessel inwall with pull bar, can easy disassembly during maintenance; When adopting serpentine to do coalescent pack, then radially weld two Punched Steel Plates at the pressurized vessel inwall, between two Punched Steel Plates, fill serpentine.The through-hole diameter of Punched Steel Plate is the 5-10 millimeter, and the via area summation accounts between the 40-50% of Punched Steel Plate area, the through hole uniform distribution.These fillers have formed a kind of cross-flow zigzag passage, and when oily(waste)water passed through, the dispersive oil droplet produced collision coalescence to greatest extent, more helps increasing the oil droplet diameter, improve oily water separation efficient.
Glass reinforced plastic inclined tube filler has been adopted in the disengaging zone.Its filling structure is: fix a water-stop sheet respectively before and after glass reinforced plastic inclined tube filler, water-stop sheet is fixed on the pressurized vessel inwall, and water-stop sheet becomes 45-70 ° of angle with the axis of pressurized vessel.Glass reinforced plastic inclined tube filler lower end is the steel carriage, and the steel carriage is fixed on pressurized vessel inwall and the dividing plate.The glass reinforced plastic inclined tube is bonded to the lumphy structure at 45-70 ° of inclination angle, and individual layer is installed on the steel carriage.Oily(waste)water passes through along the glass reinforced plastic inclined tube filler at 45-70 ° of inclination angle from top to bottom, has accelerated the speed that oil droplet is separated from water.
Adopting glass reinforced plastic inclined tube filler in the disengaging zone, is to have used shallow pool theory, and this theory is thought: the flow velocity of each point equates on (1) water-carrying section, and the horizontal component velocity during oil droplet particle come-up equals flow velocity; (2) the oil droplet particle floats with constant speed; (3) floating to the water surface on the oil droplet promptly is removed.Flow along the glass reinforced plastic inclined tube according to this theory sewage, the oil droplet liter floats to glass reinforced plastic inclined tube inwall and promptly is removed, and glass reinforced plastic inclined tube filler has shortened the floating distance of liter of oil droplet.
At top, pressurized vessel disengaging zone oil discharge outlet is arranged, isolated oil can be discharged by oil discharge outlet.
In pressurized vessel coagulation district, coalescent district and disengaging zone bottom, sewage draining exit is arranged respectively, isolated particulate matter can be discharged by sewage draining exit.
The other end at the relative sewage inlet of pressurized vessel has water out, and isolated water can be discharged by water out.
In order to control freeboard, water outlet is steady, and water out adopts the upward bent receipts water of inner spout hydraucone.
Make in order to simplify pressurized vessel, the convenient welding pressurized vessel is made cylindric, and two ends are ellipsoid shape, in the coagulation district, coalescent district and disengaging zone have manhole respectively.
At the pressurized vessel top water-oil interface monitor is installed.By the water-oil interface monitor, in time monitor the water-oil interface height in the multi-functional sewage treater, regularly reclaim sump oil automatically.
The beneficial effects of the utility model are: the multifunctional oil-contained waste water treater belongs to oil-gas field produced water disposal device, is used for the oil well produced water treatment of water oil-containing smaller or equal to 1000mg/L, reaches after the processing below the oil-containing 50mg/L.Realized airtight oil removing, the efficient height; Compact construction is saved the purpose of taking up an area of.In addition, the multifunctional oil-contained waste water treater can be prefabricated in the factory; Being fit to middle-size and small-size oily water treatment station uses.
