TECHNICAL FIELD
[0001] The utility model relates to the technical field of gas-liquid separation, and specifically relates to a gas-liquid separation device. BACKGROUND
[0002] The gas-liquid separation device separates gas and liquid according to their density. Since the density of gas is different from that of liquid, when the gas and liquid flow together, the gas will change direction if it encounters an obstruction, while the liquid will continue to move forward due to inertia. The forward liquid will adhere to the surface of the obstruction and collect together due to gravity and then be discharged through the discharge pipe.
[0003] The packing in the gas-liquid separation device cannot effectively overcome the wall flow effect. A liquid redistribution device needs to be installed every certain height to prevent dry wall phenomenon on the surface of the packing. However, the installation of the liquid redistribution device reduces the space utilization of the packing tower. The packing is generally fixed inside the device, which will cause personnel to climb and disassemble during the replacement of the packing, increasing the difficulty of replacing the packing. SUMMARY
[0004] The utility model aims at providing a gas-liquid separation device to solve the above-mentioned defects in the prior art.
[0005] The gas-liquid separation device comprises a separation tank body and a separation cavity. An exhaust pipe is connected to one side of the separation tank body. An injection pipe is arranged above the separation tank body. A settling mechanism is arranged inside the separation tank body. The settling mechanism separates gas and liquid through the separation cavity arranged inside, thereby separating impurities in high-temperature steam and condensing and discharging the liquid. A discharge mechanism is arranged outside the separation cavity. The discharge mechanism vertically lifts the separation cavity, thereby guiding the separation cavity out of the inside of the separation tank body and reducing the difficulty of replacing the filter element in the inside of the separation cavity.
[0006] Preferably, the settling mechanism comprises a liquid discharge pipe, a separation cavity, a flange, a limiting disc, a discharge disc, a liquid discharge hole, and a packing block. The liquid discharge pipe is connected to the bottom end of the separation tank body. The separation cavity is arranged inside the separation tank body. The limiting disc is arranged inside the separation cavity. The flange is connected to the top end of the limiting disc. The packing block is arranged below the limiting disc. The discharge disc is welded to the bottom end of the separation cavity. The liquid discharge holes are arranged on the surface of the discharge disc.
[0007] Preferably, the separation tank body is connected to the bottom end of the packing block through the discharge disc arranged inside.
[0008] Preferably, the discharge mechanism includes a separation tank, a spring column, a support seat, and a guide groove. The separation tank has guide grooves arranged in a rectangular pattern inside. The support seat is connected to the outside of the guide groove. The top of the support seat is connected to the bottom of the spring column. The top of the spring column is connected to the inside of the guide groove.
[0009] Preferably, the guide groove is connected to the top of the support seat through an internally provided spring column.
[0010] Preferably, the guide groove is connected to the bottom end of the separation cavity via a support seat connected to the outside.
[0011] Compared with the prior art, the present invention has the following advantages:
[0012] 1. The height of the limiting disc is adjusted by the irregularly shaped separation chamber. At the same time, the irregularly shaped separation chamber increases the gas flow rate. The separation chamber increases the contact area between the gas and the packing block, promotes the renewal of the liquid phase surface, and improves the gas-liquid mass transfer rate. The installation length of the combined packing structure is adjusted by screws to make the packing structure meet the usage requirements of the packing in the separation tank, eliminating the need to reserve extra packing space for the separation chamber.
[0013] 2. After separation is completed, the operator opens the top of the separation tank according to the replacement requirements of the packing blocks, and moves the lifting seat vertically downward through the spring column to adjust the height of the lifting seat, thereby positioning the separation chambers of different sizes. Then, the spring column lifts the lifting seat and the separation chamber vertically, thereby reducing the difficulty of replacing and maintaining the separation chamber. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] like Figures 1 to 6 As shown, the gas-liquid separation device includes a separation tank 1 and a separation chamber 6. An exhaust pipe 2 is connected through one side of the separation tank 1, and an injection pipe 3 is arranged on the top of the separation tank 1. A settling mechanism 5 is arranged inside the separation tank 1. The settling mechanism 5 separates the gas and liquid through the separation chamber 6, thereby separating impurities in the high-temperature steam and condensing and discharging the liquid. A discharge mechanism 15 is arranged on the outside of the separation chamber 6. The discharge mechanism 15 vertically lifts the separation chamber 6, thereby completing the discharge of the separation chamber 6 out of the separation tank 1, reducing the difficulty of replacing the internal filter element of the separation chamber 6.
[0024] In this embodiment, the settling mechanism 5 includes a drain pipe 4, a separation chamber 6, a flange 7, a limiting plate 8, a discharge plate 10, a drain hole 11, and a packing block 13. The drain pipe 4 is connected to the bottom end of the separation tank 1. The separation tank 1 is provided with a separation chamber 6 inside. The separation chamber 6 is provided with a limiting plate 8 inside. The top end of the limiting plate 8 is connected to the bottom end of the flange 7. The packing block 13 is provided below the limiting plate 8. The bottom end of the separation chamber 6 is welded to the discharge plate 10. The surface of the discharge plate 10 is circumferentially distributed with drain holes 11, through which the separated liquid is discharged into the interior of the separation chamber 6.
[0025] In this embodiment, the separation tank 1 is connected to the bottom end of the packing block 13 through the internally provided discharge plate 10, and the top of different numbers of packing blocks 13 are pressed and positioned by the discharge plate 10.
[0026] In this embodiment, the discharge mechanism 15 includes a separation tank 1, a spring column 9, a lifting seat 12, and a guide groove 14. The guide groove 14 is rectangularly distributed inside the separation tank 1. The lifting seat 12 is connected to the outside of the guide groove 14. The bottom end of the spring column 9 is connected to the top end of the lifting seat 12. The top end of the spring column 9 is connected to the inside of the guide groove 14.
[0027] In this embodiment, the guide groove 14 is connected with the top end of the lifting seat 12 through the internally arranged spring column 9, and the side of the lifting seat 12 is positioned through the spring column 9, so as to facilitate the dynamic adjustment and lifting of the lifting seat 12.
[0028] In this embodiment, the guide groove 14 is connected with the bottom end of the separation cavity 6 through the externally connected lifting seat 12, and the high-pressure water vapor is accumulated and separated through the separation cavity 6.
[0029] The gas-liquid separation device in actual application includes the following working contents:
[0030] Step 1: In the use process, according to the amount of the injected once, the filler block 13 is installed in the inside of the separation cavity 6, the top end of the filler block 13 is compressed through the limiting disc body 8, the outside of the limiting disc body 8 and the separation cavity 6 is locked through the screw, the injection pipe 3 is penetrated and connected with the top end cover of the separation tank body 1, the flange plate 7 is bolted and separated from the injection pipe 3, the separation cavity 6 is attached to and moved downward with the lifting seat 12 by vertically pressing the injection pipe 3 and the separation cavity 6, and then the installation of the lifting seat 12 and the separation cavity 6 is completed, so that the separation tank body 1 is tightly locked with the tank cover.
[0031] Step 2: In the whole filler block 13, when the gas passes through, the gas and the liquid on the surface of the filler block 13 occur gas-liquid mass transfer, heat transfer or reaction through the liquid film. Because the surface area of the filler block 13 is large, the gas-liquid mass transfer opportunity is increased, and the separation efficiency of the filler is higher. At the same time, the heat in the steam is radiated by the separation cavity 6, so that the material can be fully separated.
[0032] Step 3: The gas is discharged through the top end arranged exhaust pipe 2, and the liquid is directly guided out of the inside of the separation cavity 6 through the bottom end equally spaced arranged liquid discharge hole 11 of the bottom end arranged discharge disc body 10, and the liquid is discharged through the bottom end arranged liquid discharge pipe 4. At the same time, the gas is diffused into the inside of the separation tank body 1 through the gas hole arranged on the outside of the separation cavity 6, and the gas is discharged through the exhaust pipe 2 arranged on one side of the separation tank body 1.
[0033] Step 4: When the filler block 13 needs to be replaced, the cover arranged on the top end of the separation tank body 1 is opened, so that the cover is separated from the injection pipe 3. After the bottom end of the separation cavity 6 loses the bottom end pressure of the injection pipe 3, the four groups of lifting seats 12 are vertically pulled through the spring column 9, so that the lifting seats 12 slide on the outside of the guide groove 14, the separation cavity 6 is vertically moved out of the inside of the separation tank body 1, and the flange plate 7 is bolted and separated from the injection pipe 3.
[0034] Thus, the disclosed embodiments are merely exemplary, and are not the only way to implement the present application. All changes within the scope of the present application or equivalent to the scope of the present application are included in the present application.
