Detailed Description
The technical scheme of the invention is further described below with reference to the accompanying drawings.
Referring to fig. 1-2, a gas-liquid separation mechanism is described for separating a liquid-containing gas. The gas-liquid separation mechanism is arranged in a pipe body 1 distributed along the vertical direction, and the pipe body 1 comprises an inlet 2 arranged at the lower end of the pipe body and used for introducing liquid-containing gas, a first outlet 4 arranged at the upper end of the pipe body and used for introducing separated gas, and a second outlet 5 arranged at the lower end of the pipe body and used for introducing separated liquid.
The gas-liquid separation mechanism includes a fan 3 provided in the pipe body 1 for blowing a liquid-containing gas toward an inner peripheral portion of the pipe body 1, a condensate plate 6 provided between the inner peripheral portion of the pipe body 1 and the fan 3, and a spiral guide passage 7 provided between the inner peripheral portion of the pipe body 1 and the condensate plate 6.
The condensate plate 6 comprises a plate body, micropores formed on the plate body and used for guiding the liquid-containing gas to the inner peripheral part of the pipe body 1, and a water-and oil-collecting coating coated on the condensate plate 6. In this embodiment, the plurality of micro-holes are irregular in path for guiding the liquid-containing gas from one side of the plate body to the other side thereof, i.e., for guiding the liquid-containing gas from the side of the plate body near the blower 3 to the other side of the plate body near the spiral guide passage 7. When the liquid-containing gas passes through the micropores, the liquid is condensed into liquid drops, and the liquid drops are primarily separated from the gas. The condensate plate 6 is cylindrical and is coaxially distributed with the pipe body 1. By arranging the water-gathering and oil-gathering coating, the liquid condensing capacity of the condensate plate 6 is further improved, and the gas-liquid separation efficiency is improved. The water and oil coalescing coating may be a PTFE latex.
The upper end of the spiral guide channel 7 communicates with the first outlet 4, and the lower end of the spiral guide channel 7 communicates with the second outlet 5. The spiral guide channels 7 are distributed coaxially with the tube body 1. In this embodiment, the spiral guide channel 7 is a spring provided between the inner peripheral portion of the pipe body 1 and the outer peripheral portion of the cylindrical condensate plate 6, and the elastic expansion direction of the spring is distributed in the vertical direction, and by providing the spring, the path length of the spiral guide channel at the same height can be adjusted to correspondingly adjust the path length of the gas and the liquid flowing on the spiral guide channel, that is, adjust the gas-liquid separation speed. By providing the inner peripheral portion of the spiral guide channel 7 in contact with the outer peripheral portion of the condensate plate 6 and the outer peripheral portion of the spiral guide channel 7 in contact with the inner peripheral portion of the pipe body 1, the condensed liquid in the micropores can directly flow into the spiral guide channel 7. The spiral guide channel 7 is spirally rising in a counterclockwise direction (see fig. 1, the spiral guide channel 7 is viewed from a top view of fig. 1). Through setting up this spiral direction passageway 7, not only can make the liquid that separates flow down along the spiral direction and assemble, can also make the gaseous upward and downward flow of separation along the spiral direction, and gaseous in the spiral rising with the spiral in-process that descends, because centrifugal force effect can be further with the liquid that does not separate, the liquid that separates uses spiral direction passageway 7 as the carrier and continues to flow down, and separation speed is faster, separation efficiency is higher.
The gas-liquid separation mechanism further comprises an isolation cover 8 arranged in the pipe body 1, the isolation cover 8 comprises a cover body 81 for separating the spiral guide channel 7 and the first outlet 4, a through hole 82 formed in the cover body 81, and a blocking piece 83 arranged on the periphery of the outer side of the cover body 81, wherein the blocking piece 83 is used for blocking gas from entering the through hole 82 along the spiral direction of the spiral guide channel 7, and the isolation cover 8 is arranged between the condensate plate 6 and the first outlet 4 because the spiral guide channel 7 is attached to the condensate plate 6. In this embodiment, the lower end of the cover 81 is provided on the blower 3, and the cover 81 is gradually tapered open in an upward direction. The two sides of the blocking member 83 contacted by the gas in the spiral direction of the spiral guide channel 7 are a first side 84 and a second side 85, respectively, the blocking member 83 is connected to the cover 81 by the first side 84, and the second side 85 is located at a side of the through hole 82 away from the cover 81. With this arrangement, the gas forms a swirl flow rotating counterclockwise in the spiral guide passage, and after returning from the micropores, flows counterclockwise around the separator 8, and the gas cannot directly enter the through hole 82 due to the arrangement of the blocking member 83. When the gas always flows in the anticlockwise direction until the gas is accumulated, a larger reverse pressure is generated at the accumulation position, and under the action of the reverse pressure, the gas flows around the isolation cover 8 in the clockwise direction, enters the through hole 82 and then enters the first outlet 4 from the through hole 82; the time for the gas to flow around the isolation cover 8 is increased, and the gas-liquid separation effect is improved.
The fan 3 is located in the middle part of the pipe body 1, and the gas-liquid separation mechanism further comprises a blocking plate 9 which is arranged above the fan 3 and used for blocking the upward flowing out of the gas containing liquid, and a blocking cover 10 which is arranged in the pipe body 1 and used for preventing the gas from flowing out from the lower part of the fan 3, wherein the blocking cover 10 gradually tapers and contracts along the upward direction. By arranging the blocking plate 9, liquid-containing gas can only enter the condensate plate 6 from the side part of the fan 3; by providing the blocking cover 10, when the gas flows down the spiral guide channel 7, it flows up the spiral guide channel 7 again after bottoming.
The working procedure of this embodiment is specifically described below:
firstly, liquid-containing gas is introduced into a pipe body 1 from an inlet 2, and enters a condensate plate 6 under the centrifugal action of a fan 3, most of liquid is condensed through micropores, and the liquid enters a spiral guide channel 7 through the micropores and flows downwards along the spiral guide channel 7; the gas flows upwards or downwards along the spiral guide channel 7 through the micropores, the bottomed gas also flows upwards along the spiral guide channel 7 due to the blocking of the lower part by the blocking cover 10, the gas can further separate the liquid which is not separated out due to the centrifugal force in the flowing process, and after the gas rises to the top, the gas flows around the isolation cover 8 in the anticlockwise direction, and the gas cannot enter the through hole 82 due to the blocking piece 83, after the gas always flows to the accumulation in the anticlockwise direction, a larger reverse pressure is generated at the accumulation position, the gas flows around the isolation cover 8 in the clockwise direction under the reverse pressure, enters the through hole 82, and then enters the first outlet 4 from the through hole 82 and is introduced into the external environment; the separated liquid is recovered from the second outlet 5.
The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and to implement the same, but are not intended to limit the scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of the present invention.
