Description
Technical field
The present invention relates to a kind of gas-liquid separator, particularly a kind of gas-liquid separator that utilizes centrifugal force separate to combine with gravity settling separation belongs to the HVAC refrigerating field.
Technical background
Gas-liquid separator is a kind of device for gas-liquid separation, and its function is: the gateway that is installed in gas compressor is used for gas-liquid separation, gas phase demist behind the fractionation cat head cooler, various gas scrubbing towers, the gas phase demist on absorption tower etc.The method of gas-liquid separation has a lot, separates etc. such as gravitational settling, centrifugal force separate, baffling separation, filler.The most frequently used in the industry is gravity settling separation and two kinds of gas-liquid separating methods of centrifugal force separate.The principle of gravity settling separation is, because gas is different from the density of liquid, liquid is when flowing with gas, liquid can be subject to action of gravitation, produce a downward speed, and gas still flows towards original direction, that is to say liquid and gas separative tendency in gravitational field, and downward liquid is attached to pool together on the wall by delivery pipe and discharges.Its advantage is, simplicity of design, equipment making is simple, resistance is little; Shortcoming is, separative efficiency is low, and equipment volume is huge, and it is many to take up room.And the principle of centrifugal force separate is, because gas is different from the density of liquid, liquid and gas are mixed when flowing, the centrifugal force that liquid is received is greater than gas, so liquid has the tendency of centrifugation, liquid is attached to separate on the wall and pools together downwards owing to action of gravitation, discharges by delivery pipe.Its advantage is, the sedimentation of separative efficiency force of gravity is high, and the sedimentation of volume ratio gravity reduces a lot, and the centrifugation structure can be used in the pressure vessel working stability; Shortcoming is, the segregational load narrow range, surpass liquid-vapor mixture regulation flow velocity after, separative efficiency sharply descends, the resistance ratios gravity settling separation is large.So develop aobvious particularly important of a kind of gas-liquid separation device that centrifugal force separate and gravity settling separation principle are combined.
The deficiency of existing single principle gas-liquid separation device, the gas-liquid separation device that provides a kind of novel horizontal centrifugation and gravity settling separation to combine will be provided in the present invention.This gas-liquid separator is used by the combination of two kinds of gas-liquid separation principles, can reduce resistance, makes operation more stable, increases substantially separative efficiency, and equipment volume is little simultaneously, has saved space and manufacturing cost.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of novel horizontal type gas and liquid separator is provided, and the helical duct that the gas-liquid mixed of this separator is passed through first certain distance mutually carries out centrifugal force separate; Plenum chamber through certain distance carries out gravity settling separation again, can effectively utilize the overall merit of centrifugation and gravity settling separation, improve separating effect, and overcome the single shortcoming that gravity settling separation equipment is huge, separating effect is relatively poor, increase centrifugal separation equipment, bring into play the high advantage of its separative efficiency.Thereby realized simplified structure, improved the purpose of gas-liquid separation efficient.
In order to address the above problem, the present invention is achieved through technology,
A kind of novel horizontal type gas and liquid separator comprises housing, liquid-phase outlet pipe, gaseous phase outlet pipe, gas-liquid two-phase inlet tube, helix tube, helix tube housing, the liquid collecting cavity of hermetically-sealed construction.The housing of hermetically-sealed construction is welded by cylindrical pipe, horizontal positioned; The liquid-phase outlet pipe is positioned at housing bottom, is easy to the outflow of liquid phase, and is connected with housing with Type of Welding; The gaseous phase outlet pipe is positioned at the top of seal casinghousing one end, with housing by being welded to connect; The gas-liquid two-phase inlet tube is welded on the center of housing end plug, is communicated with the import of helix tube; Helix tube accounts for 1/2nd of whole shell length, and horizontal positioned is the body that is formed by spiral-shaped winding by multi-layer piping, and aperture is offered in the bottom; The helix tube housing is wrapped in the helix tube outside, plays a supportive role; Liquid collecting cavity, namely inner barrel is the space for liquid phase and gas phase separation.The mixture of gas-liquid two-phase, enter in the helix tube from the gas-liquid two-phase inlet tube, rotate centered by horizontal axis in helix tube, i.e. centrifugal motion is because gas is different from the density of liquid, when liquid and gas are mixed motion, the centrifugal force that liquid is subject to is greater than gas, so liquid has the tendency of centrifugation, liquid is attached on the helix tube wall because action of gravitation, flow out from the aperture of helix tube bottom, with flowing into liquid collecting cavity by the helix tube housing; And the remainder gas-liquid mixture is with helical pipe outlet ejection, in liquid collecting cavity, liquid is when spraying with gas, and liquid can be subject to action of gravitation, produces a downward speed, and gas still flows towards original direction, that is to say liquid and gas separative tendency in gravitational field, downward liquid is attached on the seal casinghousing wall and pools together, and flows out with the liquid-phase outlet pipe, gas then constantly rises, and flows out from top gaseous phase outlet pipe.Separate for twice by centrifugal force separate and gravitational settling, thereby realize gas-liquid separation.
When the housing of hermetically-sealed construction was placed, slightly low dip flowed out with whole liquid in the assurance liquid collecting cavity.
Helix tube is positioned at the inside of spiral shell, and edge and housing have certain distance, have several apertures on the wall of outer, screwed pipe bottom, and tapping makes things convenient for liquid phase to flow out from hole without burr.
The screwed conduit casing body length is about half of total seal casinghousing length, and support is arranged at the bottom, and with horizontal direction certain angle is arranged, and slightly low dip is conducive to liquid phase and flows out, and falls into liquid collecting cavity.
The screwed pipe outlet is 100 ° ~ 110 ° with the horizontal direction angle, is beneficial to the gravity settling separation of carrying out gas-liquid, also is beneficial to gas and flows out from gaseous phase outlet.
Adopted the said structure scheme, the invention has the beneficial effects as follows:
This gas-liquid separator is applicable to the separation of various gas-fluid two-phase mixtures, be specially adapted to the separation of gas-liquid mixed agent behind throttling arrangement in the refrigeration system, the gas-liquid two-phase inlet pipe went out to manage with throttling arrangement and was connected this moment, the liquid-phase outlet pipe connects evaporator, and the gaseous phase outlet pipe is connected directly to compressor suction duct by the resistance parts.By dual separating effect, greatly improved gas-liquid separation efficient.
Therefore, the present invention compares with existing gas-liquid separator, and concrete outstanding advantage is: (1) overcomes the vertical gas-liquid separator large shortcoming that takes up room, and it is less to take up room; (2) utilization of dual separating effect had both improved separative efficiency, made again the structure manufacturing simple; (3) good, the stable operation of adjusting function.
A kind of novel horizontal type gas and liquid separator provided by the invention is structurally made simply, in operation feasibility is arranged, and for practical application provides great convenience, can be widely used in evaporating, in the industrial operations such as gas-liquid separation of cooling and warming.
