The top of the wire mesh foam remover 33 is connected with a plurality of L-shaped plug-ins 34 which are distributed at intervals along the circumferential direction of the wire mesh foam remover 33, the plug-ins 34 comprise plug-ins 341 positioned at the top, and the plug-ins 341 are inserted into the slide ways.
As shown in fig. 3, two wire mesh demisters 33 are oppositely enclosed in a circular shape and sleeved on the outer side of the cylinder three 17, and a positioning plate 32 is clamped between the two wire mesh demisters 33.
The outside of straight section of thick bamboo 601 still is equipped with the shutoff subassembly, and the shutoff subassembly includes shutoff piece one 7 and shutoff piece two 8, and shutoff piece one 7 includes arc shutoff board one and connects two otic placodes one 701 at arc shutoff board one both ends, still includes the inboard arc cushion 702 of connection at arc shutoff board one, and the shape of arc cushion 702 and the shape looks adaptation of inserted port 603, and arc cushion 702 can insert in the inserted port 603 and press on silk screen demister 33. The second plugging piece 8 comprises a second arc plugging plate and two second ear plates 801 connected to two ends of the second arc plugging plate, and the first arc plugging plate is longer than the second arc sealing plate.
The arc-shaped plugging plate I and the arc-shaped plugging plate II are oppositely buckled on the outer side of the cylinder III 17, the arc-shaped plugging plate I is covered on the outer side of the inserting port 603, and the arc-shaped cushion block 702 passes through the inserting port 603 and is pressed on the silk screen foam remover 33. The first lug plate 701 and the second lug plate 801 positioned on the same side are penetrated with a connecting bolt 9, and the connecting bolt 9 enables the first blocking piece 7 and the second blocking piece 8 to be tightly pressed on the outer side of the third cylinder 17.
As shown in fig. 1 and 2, the rotation driving mechanism is a driving motor 1, the driving motor 1 is mounted on a supporting plate 201, and the driving motor 1 is in transmission connection with a central shaft 11 and is used for driving the central shaft 11 to rotate.
The outlet pipe 5 is connected with a negative pressure suction device, and the negative pressure suction device can assist the gas-liquid mixture to flow in the vertical cylinder 6 along the paths of the first channel, the second channel and the third channel, so that the flow power of the gas-liquid mixture is enhanced. The negative pressure suction apparatus is a prior art, and its structure is not described in detail here.
The first valve 31 and the second valve are opened or closed by electric control, and when the valves are opened, solid impurities with larger volume can pass through the valves, and structures such as butterfly valves with larger flow areas can be adopted.
When the invention is used, the gas-liquid mixture is introduced from the inlet pipe, flows along the first channel, the second channel and the third channel, and the gas-liquid mixture flows spirally at high speed due to the spiral blades arranged in the channels, so that heavier liquid is thrown out under the centrifugal action in the flowing process, and flows downwards along the side walls of the cylinders and the spiral blades.
The liquid separated in the first and second channels flows into the liquid collecting hopper 24 through the liquid discharging hole 221, and when the liquid in the liquid collecting hopper 24 reaches a certain amount, the first valve 31 is opened, so that the liquid in the liquid collecting hopper 24 is discharged into the collecting section 602. Because the horizontal circular plate 22 is arranged, and the liquid blocking cover 26 is arranged at the liquid discharging hole 221, the gas-liquid mixture can not be in great contact with the liquid in the liquid collecting hopper 24 in the process of flowing from the channel to the channel II, and the liquid is prevented from being mixed into the gas-liquid mixture again. After being carried up by the gas-liquid mixture, a small amount of liquid in the liquid collecting hopper 24 can be separated when passing through the liquid blocking column, so that the liquid collected at the bottom end of the liquid blocking column is dropped into the liquid collecting hopper 24 through the liquid drain hole 221.
The liquid separated in the third channel flows down into the collecting section 602, and when the liquid in the collecting section 602 reaches a set value, the second valve is opened to discharge the liquid in the collecting section 602.
After the gas-liquid mixture passes through the first channel, the second channel and the third channel, most of liquid in the gas-liquid mixture is separated, the rest gas flows upwards between the third cylinder 17 and the straight cylinder section 601, and is discharged through the outlet pipe 5 after passing through the silk-screen defoaming mechanism, and the silk-screen defoaming mechanism can remove tiny liquid drops contained in the gas, so that the gas-liquid separation effect is further enhanced.
After this gas-liquid separation device used a period of time, need clear up inside, can close valve one 31, valve two earlier this moment, pour into the cleaning solution into in the upright section of thick bamboo 6 by the inlet tube, later start driving motor 1, center pin 11 corotation drives each helical blade and rotates, can strike off the impurity on the lateral wall of each drum when helical blade rotates, and helical blade produces stirring effect to the cleaning solution simultaneously, the reinforcing is to helical blade self cleaning effect.
When the central shaft 11 rotates positively, the connecting plate 28 is driven by the threaded shaft section 21 to move upwards, the horizontal circular plate 22 is driven by the connecting plate 28 to move upwards, the horizontal circular plate 22 is separated from the inner side wall of the liquid collecting hopper 24, so that a space is formed between the horizontal circular plate 22 and the inner side wall of the liquid collecting hopper 24, the communication space between the channel II and the inner cavity of the liquid collecting hopper 24 is enlarged, and when cleaning is finished, cleaning liquid in the vertical cylinder 6 and scraped impurities are required to be scraped off, the impurities are convenient to flow into the liquid collecting hopper 24 and are discharged from the liquid discharging channel 30, and blockage caused by smaller size of the liquid discharging hole 221 is avoided.
After the cleaning is finished, the driving motor 1 drives the central shaft 11 to turn over for a set number of turns, the connecting plate 28 is driven to move downwards to an initial position, and at the moment, the horizontal circular plate 22 is restored to an initial state that the outer end is in contact with the inner side wall of the liquid collecting hopper 24.
The wire mesh defoaming mechanism also needs to be cleaned or replaced regularly, so that the wire mesh defoaming mechanism needs to be detached from the equipment regularly, when the wire mesh defoaming mechanism is detached, the connecting bolts 9 are detached firstly, the first plugging piece 7 and the second plugging piece 8 are detached from the vertical cylinder 6, and then the two wire mesh foam removers 33 are taken out sequentially. When the wire mesh defoaming mechanism is installed, one wire mesh defoamer 33 is inserted into the vertical cylinder 6 from the insertion port 603, the insertion plate 341 at the top of the wire mesh defoamer 33 is inserted into the insertion slot, then the wire mesh defoamer 33 is rotated, and when the wire mesh defoamer 33 moves to be in contact with the positioning plate 32, the other wire mesh defoamer 33 is inserted into the vertical cylinder 6 from the insertion port 603 in the mode.
