Description

Technical Field

[0001] The utility model relates to the field of gas-liquid separation, in particular to a raw gas liquefaction separation device. Background Art

[0002] The gas-liquid separator adopts the principle of centrifugal separation and wire mesh filtration to achieve liquid removal. It is a separation device that realizes separation through the different specific gravities of gas and liquid. When the liquid flows with the gas, the liquid will be affected by gravity to a greater extent, resulting in a downward speed, while the gas still flows in the original direction. In other words, the liquid and gas tend to separate in the gravity field. The downward liquid adheres to the wall, gathers together, and is discharged through the discharge pipe. In the application process of natural gas field, during the compression process of natural gas raw materials, the gas needs to be dehydrated and liquid removed in advance through the gas-liquid separation device before compression. At present, the core devices for achieving gas-liquid separation mainly include wire mesh demister, cyclone separator, etc.

[0003] The Chinese patent CN202122197242.2 discloses a gas-liquid separation device, which reduces the economic cost of the manhole design by adding a flange to the top of the cylinder, and realizes the rapid installation and disassembly of the separation and filtration components through the setting of support plates, connecting columns and limiters, thereby improving the maintenance convenience of the separation and filtration components;

[0004] This structure has certain advantages, but still has some shortcomings:

[0005] When disassembling the separation filter component, it is necessary to extend it into the interior of the cylinder and maintain this state until the fastening nuts above the multiple groups of connecting columns are loosened, so as to remove the separation filter component. The method of installing or disassembling the separation filter component by relying on the fastening nuts is relatively troublesome and inconvenient, and there are certain safety hazards, which is not conducive to the safe and convenient maintenance of the separation device.

The support ring 51 is fixed to the inner side of the tank body 2, the bottom end of the mounting tube 52 is in contact with the support ring 51, the left end of the mounting tube 52 is fixed with the anti-skid pad 53, the reinforcement 54 is installed inside the right end of the mounting tube 52, the outer side of the support frame 55 is fixed with the mounting tube 52, and the wire mesh demister 56 is placed on the top thereof, the outer side of the fixing frame 57 is threadedly connected to the mounting tube 52, and the bottom end thereof is in contact with the wire mesh demister 56.

[0030] In this embodiment, the cross-section of the fixing frame 57 is in the shape of an "I" character, which is convenient for pressing and fixing the wire mesh demister 56, and can be connected and fixed with the mounting tube 52, so as to achieve stable fixation of the wire mesh demister 56, so that it can be stably installed and stably guide the gas-liquid separation. The support frame 55, the wire mesh demister 56, and the fixing frame 57 are each provided with two groups, which are symmetrically distributed up and down, so as to facilitate the double gas-liquid separation of the input gas and improve the efficiency of gas-liquid separation.

[0031] See also Figure 5-6 The utility model provides a raw gas liquefaction separation device, the reinforcement member 54 includes an assembly 541, a motor 542, a double-threaded screw 543, a slide 544, a connecting rod 545, a connecting frame 546, a top plate 547, and a second anti-slip pad 548. The assembly 541 is installed inside the right end of the installation tube 52, and the motor 542 is installed inside it. The bottom end of the motor 542 is transmission-connected to the double-threaded screw 543 by a coupling, and the bottom end of the double-threaded screw 543 is movably connected to the assembly 541. The inner side of the slide 544 is threadedly connected to the double-threaded screw 543. The right end of the slide 544 is rotatably connected to the connecting rod 545, and the right end of the connecting rod 545 is rotatably connected to the connecting frame 546. The right end of the connecting frame 546 is fixed with a top plate 547, and the top plate 547 slides inside the assembly 541, and its right end contacts the tank body 2.

[0032] In this embodiment, a second anti-skid pad 548 is fixed to the outer side of the right end of the top plate 547, so that when the top plate 547 is pushed to the right and squeezed against the tank body 2 to achieve the tight installation of the filter device 5, the second anti-skid pad 548 increases friction and strengthens the tight connection, so that the filter device 5 is firmly installed inside the tank body 2, and the wire mesh demister 56 is stably installed to separate the liquid in the gas. The cross-section of the top plate 547 is "U"-shaped, which is convenient for installing the connecting frame 546 at the left end, and when the top plate 547 is pushed out to the right, under the influence of the "U"-shaped structure, the top plate 547 and the assembly 541 still have an overlapping area, so that the external gas cannot penetrate into the interior of the assembly 541. The sliding seat 544 and the connecting rod 545 are both provided with two groups, which are symmetrically distributed up and down, so as to stably push the connecting frame 546 and the top plate 547 to be pushed out to the right, thereby improving the balance of the top plate 547.

[0033] Among them, when the top plate 547 is pushed out and tightly connected with the mounting tube 52 by means of extrusion force, the mounting tube 52 is slightly displaced, causing the mounting tube 52 to move to the left. Since the circle diameter of the mounting tube 52 is close to the circle diameter of the tank body 2, the moving distance is small, and the outer diameter of the mounting tube 52 is still maintained within the support range of the support ring 51, thereby effectively avoiding the gas from passing through the support ring 51 and the gap between the mounting tube 52 and the tank body 2.

[0034] See also Figure 1-Figure 6 When in use, the servo motor 8 is started to drive the pulley 9, the V-belt 10, and the second pulley 11 to move, so that the connecting shaft 12 drives the movable cover 7 fixed at the top to rotate synchronously, and the top of the tank body 2 is removed to completely expose the internal structure;

[0035] Then, the installation cylinder 52 is placed into the tank body 2 so that its bottom end contacts the support ring 51 to achieve preliminary positioning. Then, by starting the motor 542, the double-threaded screw 543 is driven to rotate, driving the two sets of slide seats 544 to move toward each other, and under the action of the connecting rod 545 and the connecting frame 546, the top plate 547 and the second anti-skid pad 548 are evenly pushed to move to the right to resist the tank body 2, and force is continuously applied until the left end of the installation cylinder 52 and the right end of the top plate 547 completely squeeze the tank body 2, and the installation cylinder 52 is stably installed by relying on the action force between the installation cylinder 52 and the tank body. After the installation is completed;

[0036] The raw material gas is input from the air inlet pipe 4, the gas floats upward, and the heavier liquid falls downward. When the gas containing mist passes through the wire mesh demister 56 at a certain speed, the mist collides with the wire mesh filaments due to inertia, and is attached to the surface of the filaments. On the surface of the filaments, the mist further diffuses, and due to the gravity sedimentation of the mist itself, the mist forms larger droplets, and flows along the filaments to the interweaving place, drips to the bottom of the tank body 2, and is subsequently discharged through the water outlet pipe 3;

[0037] The gas removed from the mist liquid continues to float upward and is discharged and collected through the gas outlet pipe 6 at the top;

[0038] When the internal wire mesh demister 56 needs to be maintained, the top plate 547 is controlled to be reset, thereby releasing the force between the mounting tube 52 and the tank body, making it easy to quickly remove the mounting tube 52, and with the help of the anti-slip pad 53, the mounting tube 52 is stably laid on the ground, and at the same time, the fixing frames 57 at both ends are removed by threads, and the internal wire mesh demister 56 can be maintained and replaced.
