Description
Technical field
Utility model relates to a kind of gas-liquid separation device, especially efficiently removes the centrifugal gas-liquid separator of fine droplets about having from gas.
Background technology
Solution heating vaporization produces indirect steam and often carries a large amount of fine drop (diameter is usually below 10 μ m) secretly, and produces with foam, must be removed (being commonly called as foam removal or demist), otherwise can cause the useful products loss or pollute condensed water.
Prior art is gas-liquid separator inside (built-in) or foam removal is set outside (external) or demister has two kinds usually: one is the inertia capture, utilize steam to turn to suddenly, make drop have little time to turn to bump wall to be captured, for example venetian blind type, board-like, the deflector type of eddy flow; Two are the collision interception, utilize the collision of steam and solid wall, drop aggegation under the effect of wall interfacial tension, and droplet is accumulated into big drop and falls, and reaches the drop separation in the gas, for example screen type, straight-bar type.The foam removal separating effect, wire mesh demister is best, can reach more than 99% the above drop arresting efficiency of 5 μ m, also can reach about 60% the drop of 3 μ m.But wire mesh demister, exist easily and stop up, and shortcoming such as poor, the cost height of easy cleaning, corrosion resistance, maintenance difficult not, in for example organic wastewater evaporation gas-liquid separation of evaporation organic matter, especially large-scale gas-liquid separation is not used, more employing is at centrifugal gas-liquid separator, steam outlet is provided with tapered cap such as Fig. 1, makes below 1 outlet 1.2 of centrifugation tube tapered cap 2 is set, and band foam gas collides with it and carries out the separation of drop secondary.This kind gas-liquid separator foam removal efficient is relatively low, and 5 μ m drop separation efficient are lower than 90%, cause condensed water COD height, reach 2000mg/L～3000mg/L.The disclosed evaporimeter Despumation device of Chinese patent CN2274322 is the remodeling of above-mentioned Despumation device, and tapered cap is provided with several layers, and periphery is connected with evaporator wall, has the 7-10mm through hole on it.Just simply with silk screen foam removal and tapered cap foam removal combination, resistance is bigger, and because its perforate is bigger, still lower to fine drop foam removal efficient, foam removal is not thorough, and is used for viscous material, also can result in blockage for Despumation device in this separator.
The utility model content
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of foam removal separating power strong, catches foam efficient height, and the centrifugal gas-liquid separator that can not stop up.
The utility model purpose realizes that main the improvement is with end toper retaining cap before the centrifugal gas-liquid separator outlet, changes tube-in-tube structure at the bottom of the unsettled male-tapered band (is called for short unsettled awl glass) into, thereby overcomes the deficiencies in the prior art, realization utility model purpose.Specifically, the utility model centrifugal gas-liquid separator, comprise the cylinder of being with radial inlet and ejecting mouth, it is characterized in that the cylinder steam (vapor) outlet has the steam discharge short tube that extends internally, steam discharge short tube periphery have up-small and down-big, suitable for reading and barrel is gapped, annular collecting tank is arranged at the bottom taper band at the bottom of sleeve, annular sump bottom has discharging tube.
Its foam removal principle is: indirect steam with certain speed Vo for example 15～30m/s tangent line enter cylinder, the steam eddy flow rises, drop hits wall and is caught by wall under centrifugal action, barrel is dirty in the bottom drain separator in gravity effect lower edge, carries out a gas-liquid separation; Initial gross separation steam rises along the wall eddy flow, enter awl cup and steam discharge short tube interlayer by unsettled awl cup is suitable for reading with the bowl wall gap, because of the cross section reduces suddenly, cause and enter steam swirl velocity V1 and increase rapidly, V1 ≈ 1.5VO for example, high-speed rotational steam makes once more to be carried fine droplet secretly and gets rid of under centrifugal action to awl cupule wall and steam discharge tube wall, obtains secondary separation; Eddy flow steam is according to awl cup backspin, awl cup and space, steam discharge short tube interlayer cross section amplification, make steam flow rate reduce because of the cross section increases, effectively avoided too high formation of flow velocity to carry secretly once more with droplet collision, be threaded to awl cup bottom air-flow rotary speed and drop to V0, vapor stream is outside the steam discharge short tube water conservancy diversion drain separator of center; Get rid of to awl cup and central row steam pipe wall drop and glide, come together in awl cup bottom ring-type collecting tank, discharge, drop down onto the cylinder bottom according to gravity and discharge, fine droplets is efficiently separated from steam thereby reach by discharging tube along wall.
The said ring-type sump bottom of utility model discharging tube, a kind of better is to adopt the J-shaped structure, the jacking of cylinder eddy flow rising steam can be effectively avoided in curved outlet on the bottom, causes discharge opeing not smooth, more helps boring the discharge of glass liquid.
Awl cup base diameter and awl cup aspect ratio are preferably 1: 0.7-1.5.
Steam discharge short tube diameter and awl cup back cut diameter ratio are preferably 1: 1.1-1.5.
Awl the cup back cut diameter and the diameter ratio of going to the bottom are preferably 1: 1.05-1.5.
Suitable for reading and the bowl wall spacing of awl cup is preferably 100-500mm.
Steam discharge short tube bottom and awl cup bottom gap are preferably 100-500mm.
The utility model centrifugal gas-liquid separator, because the shrink-fit structure mist eliminator of cover, interior short tube at the bottom of the separator steam (vapor) outlet is provided with the outer cone band, make the steam that is entrained with fine droplet, earlier carry out a gas-liquid separation by the centrifugation tube, when steam enters awl cup demister, again it is carried out the secondary gas-liquid separation.By the variation of changing from small to big in outer cone cup and short tube interlayer cross section, center, make earlier to enter the steam eddy flow and obtain speedup, make steam obtain centrifugation once more, increase drop simultaneously and captured area; After transferring reduction of speed to, prevent that again high whole vapor stream from carrying precipitation of liquid droplets once more secretly, thereby significantly improved the foam removal effect.The secondary demister of awl cup structure has than prior art: 1, air-flow is entering the increase of tapered sleeve cup flow velocity, improved capture effect to fine drop (5～10 μ m), move down flow velocity from large to small with the tapered sleeve chessboard, effectively prevented the reentrainment of vortex gas-flow again to drop, foam removal is thorough, and gross efficiency approaches wire mesh demister; 2, inner core outer cone cup has increased the contact-making surface of gas and wall, and has shortened the migration distance of drop under centrifugal action, and arresting efficiency is improved; 3, drop and air-flow are bored outer tube and are concurrent between cup, and the disturbance and the interaction that cause in the time of can avoiding reverse have weakened the reentrainment phenomenon of air-flow, and the cohesion and the liquid that help fine drop break away from wall as early as possible; 4, the anti-property stopped up is good, and gas rotation and in droplets fall in the same way has self-purification function, thereby can not cause attached wall to stop up, and is specially adapted to contain the gas-liquid separation of the foam solution and the viscosity solution of protein; 5, resistance is little, and pressure Δ P=Ki.PgVg2/2Ki is between 2～3, and drag overall is at 200～300Pa, and what go for large-scale multiple-effect and cold boiler catches the foam operation; 6, simple in structure, make easy, cheap.
