Abstract

The invention discloses a foam remover of a compressor separator, which comprises a foam remover barrel, wherein a filter plate, a conical air guide plate and a conical condensation plate are arranged in the foam remover barrel. An air guide slot hole of the conical air guide plate is inclined relative to the plane of the conical air guide plate, so that air flow is guaranteed to uniformly and tangentially contact the surface of the conical condensation plate to increase the centrifugal force of the air flow; therefore, liquid drops in the air flow do not directly collide the surface of the conical condensation plate but contact the surface of the conical condensation plate in an inclined way, the collision force generated when the liquid drops fell onto a wall is greatly reduced to avoid the further fragmentation of the liquid drops, and the separation effect is enhanced. With a spirally rising flow guide slot below the conical condensation plate, the air flow is guided to rise spirally, the effect of improving centrifugal separation is achieved, the liquid drops fell onto the wall can be blocked and converged, the converged liquid is allowed to flow downwards along the flow guide slot, and the phenomenon that liquid drops fell onto the wall are brought away by air when the airflow speed is relatively high is prevented.

Description

A kind of compressor separator Despumation device
Technical field
The present invention relates to Despumation device, particularly a kind of compressor separator Despumation device.
Background technique
The most of middle-size and small-size nitrogenous fertilizer enterprises of China adopts coal gas production, need carry out multistage pressurization and purification to semi-water gas, later on could synthetic ammonia within the craft index scope with impurity and pressure control.Pressure process is extensive use of piston compressor, enters compressor preceding gases at different levels or needs to adopt gas-liquid separator that the moisture content in the gas is separated after water cooling by the later gas of compressor compressions at different levels.In the prior art, the separation structure that gas-liquid separator adopts is a lot, and its separation method is also a lot, has gravity settling separation, baffling separation, centrifugal force separation, silk screen separation, ultra-filtration and separation to separate with filler.But integrate, separation principle has only two kinds: the one, and utilize constituent mass (weight) difference that mixture is separated.Gas is different with density of liquid, and the quality of gas is littler than the quality of liquid under the equal volume.The 2nd, utilize disperse system grain size difference that mixture is separated.The molecular aggregates state of liquid is different with the state of aggregation of gas molecule, and the gas molecule distance is far away, and the fluid molecule distance is much closer, so gas particle is littler than liquid particle.
The normal separator that adopts in chemical plant has three kinds: (1) silk screen separates gas-liquid: adopt the Stainless Steel Wire web frame, this method belongs to mechanical type and separates, and principle is exactly the gas molecule I with by the silk screen space, and liquid molecule is big, is hindered and separates; (2) centrifugal force separates gas-liquid: adopt sped structure, the gas entrained liquids is by in the separator bottom spiral escalation flow process, the centrifugal force that the centrifugal force that liquid obtains obtains greater than gas, thereby cause liquid to break away from gas, on the separator wall, under the effect of gravity, pool together downwards then, discharge by discharge pipe.(3) baffling separates gas-liquid: because gas is different with density of liquid, liquid and gas mix when flowing, stop if run into, gas is understood baffling and is walked, and liquid continues to have a speed forward owing to inertia, and liquid forward is attached to stopping on the wall, under the effect of gravity, pool together downwards then, discharge by discharge pipe.
But all there is the deficiency of oneself in these three kinds of separators, (1) shortcoming of the separator of silk screen separation gas-liquid is: because the load of piston compressor when work is alternate load, gas will have bigger and more frequent pressure surge in the separator, after using a period of time in this case, Stainless Steel Cloth in the wire mesh demister damages easily or is broken, then along with gas enters compressor, pipeline, miscellaneous equipment, not only separating effect is very poor, and silk screen enters behind pipeline, the equipment damage equipment or valve easily, brings massive losses to safety in production; (2) shortcoming of the separator of centrifugal force separation gas-liquid is: gas can not touch with separator cylindrical shell inner wall surface when flowing in separator equably, promptly Zhou Wei gas can contact with separator cylindrical shell inwall, the gas at middle part then can not finely contact with cylinder inboard wall, thereby causes separating effect bad.When airspeed is big, the drop of wall taken away once more by gas easily, separating effect is had a greatly reduced quality; (3) baffling separates the shortcoming of the separator of gas-liquid and is: gas is also promoting wall in baffling liquid flows towards the direction of gas flow, if flow of fluid does not also break away from this Driving force of gas during to the edge of collecting wall, so the liquid of wall will be taken away again by gas.Under the certain situation of gas liquid ratio, the gas-liquid mixture flow velocity is big more, this Driving force of gas is just big more, liquid will flow to the edge of collecting wall in the shorter time, and the time that flow of fluid needs to the bottom is constant, that is to say have more the liquid of wall be pulled away and can not be separated.In addition, liquid does not have fixed shape, and easily fragmentation can produce bump in wall, turns back in the gas again and is taken away by gas thereby can produce thinner drop.And the flow velocity of air-flow is big more, and liquid is just big more with the striking force of collecting wall, and the tendency of its fragmentation is just big more, and its inertia of thin more drop is more little, is taken away by gas with regard to easy more.Because the load of piston compressor when work is alternate load, gas will have bigger and more frequent pressure surge in the separator, the flow velocity of the gas in the separator can fluctuate along with the fluctuation of pressure in the separator, thereby causes the separator job insecurity, influences separating effect.
Summary of the invention
The objective of the invention is in order to overcome the deficiency of separator in the background technique, a kind of adaptation piston compressor alternate load is provided, utilize centrifugal force to separate gas-liquid is separated gas-liquid with baffling principle simultaneously, good rigidly, and long-lived separator Despumation device, it is simple in structure, good separating effect, and can be used for multiple gas-liquid separation occasion.
Technological scheme of the present invention: a kind of compressor separator Despumation device, be arranged at the top of separator cylindrical shell inside, comprise the demister cylindrical shell, demister cylindrical shell bottom is provided with filter plate, and filter plate has reticulated cell; The filter plate top is provided with a taper aeroscopic plate and a taper lime set plate at least, and taper lime set plate is positioned at the top of taper aeroscopic plate, so alternately arranges; The taper aeroscopic plate has a plurality of uniform air guide slotted holes, and the top of taper lime set plate has vent; The demister cylinder lateral wall is provided with down comer.

Described taper lime set plate below has the spiral uprising shape guiding gutter.The direction of the uniform air guide slotted hole on the rotation direction of guiding gutter and the taper aeroscopic plate is consistent.Guiding gutter can the steering flow helical rise, and increases the time that air-flow contacts with the lime set plate, promptly increases the time that the liquid foam wall in the air-flow, increases the effect that centrifugal force separates; Simultaneously, guiding gutter can to the drop of wall stop and compile, and the liquid that converges is flowed downward along guiding gutter, when avoiding airspeed big, the drop of wall taken away by gas once more and promptly reduce the reentrainment phenomenon, thereby improve the separating effect of separator.
Described demister cylindrical shell bottom is a cylindrical body, and top is taper, and the taper top has relief opening.
Described taper aeroscopic plate is movably arranged in the demister cylindrical shell, and its top and lifting bar flexibly connect, and lifting bar cooperates with nut on being arranged on exhaust wall.The pressure of air-flow changes in separator, when the flow velocity of air-flow changes, can regulate distance between taper aeroscopic plate and the taper lime set plate by lifting bar, makes the work of separator keep stable, guarantees that separator has good separating effect.
In addition, owing to be arranged alternately a plurality of taper aeroscopic plates and taper lime set plate, the effect that baffling separates gas-liquid is played in the repeatedly variation that also can flow to during air current flow.
