(1) technical field
The present invention relates to a kind of profit solid separation device, specifically a kind of high-efficiency cyclone deoiling device.
(2) background technology
Oil-polluted water is mainly derived from industrial enterprises such as oil, petrochemical industry, iron and steel, coking, gas generating station, machining.
Oils mainly shows having a strong impact on the ecosystem and natural environment (soil, water body) to the pollution of environment.But flow to the oil slick in the water body, can hinder air reaeration behind the formation oil film, break off the source of water body oxygen; And oil emulsion in the water and dissolved oil, because aerobic effect, dissolved oxygen in decomposable process in the consume water (generating CO2 and H2O), make water body form anaerobic condition, gas concentration lwevel increases in the water body, fish and aquatile water pH value be reduced to below the normal range (NR), so that can not survive.Oily waste water flows to soil, because soil layer also can form oil film at soil to the absorption and the filtration of greasy dirt, makes air hinder the propagation of edaphon in penetrating, broken ring soil layer crumb structure.Oily waste water enters urban discharging pipeline, all can impact drainage equipment and municipal sewage plant, flow into the oil concentration of biological treatment structures combined sewage, usually can not be greater than 30～50mg/L, otherwise will influence activated sludge and biomembranous eubolism process.
Generally adopt regulating reservoir+two-stage oil interceptor for the traditional treatment process of high oil-polluted water (oil-polluted waters of discharges such as oil refining enterprise, petroleum chemical enterprise), and then the floating oil system that removes of air inlet, guarantee that the water outlet oil-containing advances biochemical treatment system again and handles below 30～50mg/L.Thorough, the stable water outlet of science and engineering skill oil removing is herein used till today always.But this technology exist technological process complexity, floor space big, invest high shortcoming, if the employing high-efficiency cyclone deoiling device can substitute three process--the regulating reservoir+two-stage oil interceptor in the traditional handicraft, and effluent quality is more excellent, the greasy dirt purity height of collecting, and moisture content is low.
High oil-polluted water conventional processes principle
Regulate sedimentation basin+advection oil separation tank+swash plate (pipe) oil interceptor and handle the oil-polluted water technological principle
Regulate sedimentation basin regulate the effect of sedimentation basin be remove be suspended in the sewage can the precipitated solid suspension; Regulate the existing regulating action of sedimentation basin the precipitation function is arranged again.The application of regulating sedimentation basin is for even the water quality adjustment of sewage before entering sewage treatment facility, make the water yield stable, sewage quality is even, be convenient to the stable operation of next step sewage treatment facility, regulating reservoir is modified but also accent amount not only, also temperature adjustment is an indispensable ring in the sewage treatment facility.
One of sewage characteristics of advection oil separation tank oil refinery industry are the oil content height, at least hundreds of, several thousand mg/litre at most.Oil is the important content of sewage disposal in the removal water.The advection oil separation tank plane is a rectangle, and oil-polluted water flows into from an end, flows out from the opposite end, and the water movement direction is a linear pattern.The task of advection oil separation tank is that the oil droplet in the water is separated from water.Oil droplet has four kinds of forms in water be missible oil, dispersed oil, oil emulsion, dissolved oil.The diameter of oil slick can utilize its proportion lighter than water generally greater than 100um, and floats naturally, advection oil separation tank utilizes these characteristics to design just, because water flow velocity is slower, oil droplet rises gradually and bubbles through the water column, and has realized water-oil separating in advection inclined plate grease pond.
The characteristics in swash plate (pipe) oil interceptor inclined plate grease pond are to be to have swash plate to increase deoiling effect and efficient in the pond.Inclined plate grease pool inner water stream on-rectilinear movement, but allow current move along the swash plate direction.Just because of this, when in the swash plate gap, moving, make the less oil droplet in the water, the oil particles of diameter 10～100um, running foul of each other forms bigger oil droplet and floats, and suspension then glides along swash plate and forms mud, reaches the effect of three separation of profit mud.The swash plate material requires smooth surface, and oily dirt free, quality are little, corrosion-resistant.The swash plate of particular design is arranged in the inclined plate grease pond that my company designs, improve deoiling effect, make the efficient in inclined plate grease pond improve 10%～20%.After oil-containing water stream passed through intersection fluid-type accumulation type corrugated plating, oil thoroughly separated with water, and oil swims on water after the separation, and face forms oil reservoir, flows into oil groove certainly, and the oil in the oil groove leans on gravity to drain in the oil plant reclaim line by oil exit pipe, is finally beaten to accumulator tank by the receipts oil pump.Suspended substance sedimentation after the separation regularly drains into the sludge drying pond by the screw rod slurry conveying machine to the V-type mud groove of oil water separator bottom.Clear water enters effluent trough by the water outlet weir plate at oil groove rear portion, through outlet pipe, enters the next stage water processing establishment.
The shortcoming of conventional processes
