Two-stage eddy flow pressure type coagulation reactor
Technical field
the utility model relates to oil field produced water-treatment technology field, is a kind of two-stage eddy flow pressure type coagulation reactor.
Background technology
oily(waste)water is the inevitable outcome of field produces, and oil field mining liquid is through after the oily water separation, and the COD of its oily(waste)water, oil-containing, volatile phenol etc. exceed standard, and belong to typical high salt organic polluting water, should utilize after treatment again or efflux.Present each oil field is transferred sewage works with oily(waste)water mostly and is focused on, and the main interpolation chemical agent that utilizes carries out the processing of coagulating settling process.This method is mainly carried out in coagulation reactor, Gu can realize oil-water-triphasic separation; Cyclonic reactor is claimed wet cyclone again, is a kind of stage equipment that separates non-homogeneous phase mixture.Can be used for accomplishing liquid clarification, liquid degassing and desanding, solid phase particles classification and several work such as separating of classification and two kinds of non-mutually soluble liquidss.Its principle of work is: suspension-s tangentially gets into hydrocyclone with higher speed by feed-pipe, owing to receive the restriction of wall of the outer-rotor, forces liquid to do top-down rotatablely moving, and usually this motion is called outer eddy flow or decline swirling motion.Solid particulate in the outer eddy flow receives centrifugal action, if density greater than around density of liquid, its suffered cf-is just big more; In case this power is greater than the liquid resistance that is produced because of motion; Solid particulate will overcome this resistance and move to the wall direction, separates with suspension-s, arrives near the particle of wall and receives the promotion of successive liquid; Along near the suspension-s that is gathered into multiviscosisty wall moves downward the arrival underflow opening, discharge from underflow opening.After liquid behind the isolation of purified (wherein also have some tiny particles) rotation continued downwards to be moved into conical section, because of the internal diameter of wet cyclone dwindles gradually, liquid in rotation speeded up.Because radially pressure distribution was uneven when liquid produced vortex motion, more little and level off to zero when arriving axis near the axis place more, become low pressure area even be the vacuum zone, cause liquid to trend towards axis direction and move.Simultaneously, because the wet cyclone underflow opening dwindles greatly, liquid can't be discharged from underflow opening rapidly, and the riser of eddy flow chamber top cover central authorities makes a part of liquid move to it owing to being in low pressure area, thereby forms rotatablely moving of making progress, and discharges from riser.At present; The patent of utilizing hydrocyclone to carry out the water treatment coagulating has " oilfield sewage multifunctional processor "; Its patent No. is CN01274775; Its structure is interior band reaction tube vertical tank, and reaction tube is arranged on the tank body center and fixes through bracing frame and tank body, establishes three reaction chambers in upper, middle and lower in its center reaction tube.After No. one medicament added, the sewage tangential got into reaction chamber top, carries out hybrid reaction with sewage; Same No. two, No. three medicament adds respectively in the reaction chamber ingress, carries out hybrid reaction respectively; Form big flocculating body at last, in the outer annular space sedimentation; Its top water outlet of jar outer annular space, collection tube is established at the top.Though this treater is provided with third order reaction by the reaction times requirement of medicament, the straight wall stream field turbulence state effect of reaction tube is little, and key is the initial velocity of tangential water inlet; The reaction tube of this reactor drum is difficult for the adjustment flow and adds dose in cylinder, influences reaction effect; Sprinkling irrigation in this reactor drum then is difficult for changing if be corroded, and difficulty of construction is bigger; The deposition easily of reaction chamber bottom influences the effective reaction space of reaction tube.
