Description

Technical Field

[0001] The utility model relates to the technical field of liquefied natural gas production, in particular to a quick-detachable dehydration device. Background Art

[0002] LNG production is the process of converting natural gas into liquid form after processing and cooling. This technology makes it easier to store, transport and use natural gas in liquid form. After natural gas is extracted from underground reservoirs, it first needs to be processed to remove impurities, moisture and other impurities to ensure the safety and effectiveness of the liquefaction process.

[0003] Among them, the dehydration step of liquefied natural gas is particularly important. Dehydration is to remove water from natural gas to ensure the quality and stability of liquefied natural gas. The presence of water may cause problems in the storage and transportation of LNG, such as icing, pipeline corrosion, etc. The dehydration tower is a common dehydration equipment, which uses chemical absorbents or physical methods to remove water from natural gas. By contacting natural gas with the absorbent, the water is absorbed or adsorbed, thereby achieving the purpose of dehydration. The existing dehydration tower was found to have the following problems in the prior art during use:

[0004] 1. The dehydration tower is filled with absorbent. When natural gas passes through the absorbent, water is captured by the absorbent, and the dried natural gas is discharged smoothly. As time goes by, the adsorbent will gradually become saturated and need to be regenerated or replaced. The process of removing the dehydrating agent from the ordinary dehydration tower is complicated, and it is impossible to quickly replace the new absorbent;

[0005] 2. Ordinary dehydration towers are equipped with multiple layers of absorbents to achieve better dehydration effects. However, the dehydration towers themselves are integrated structures. If the absorbent needs to be replaced, it can only be disassembled layer by layer, and the dehydrating agent of a certain module cannot be quickly disassembled and replaced separately. Utility Model Content

[0006] The purpose of the utility model is to provide a quick-detachable dehydration device to solve the problem that the dehydration towers mentioned in the above background technology are all integrated structures and cannot quickly and efficiently replace the saturated absorbent. To achieve the above purpose, the utility model provides the following technical solutions: a quick-detachable dehydration device, including a dehydration tower, the front of the dehydration tower is slidably connected to a first arc plate, the interior of the first arc plate is slidably connected to a second arc plate, the front of the second arc plate is rotatably connected to a block, and a dehydration component is installed inside the dehydration tower.

[0007] The dehydration assembly includes a fixed frame, the interior of the fixed frame is slidably connected with a bevel rack, one side of the bevel rack is meshed with a bevel gear, the top of the bevel rack is welded with a storage box, the interior of the storage box is provided with an adsorbent, and the interior of the bevel gear is plugged with a rotating shaft.

[0008] Further preferably, an air inlet pipe is connected to the top of the dehydration tower, a valve is installed on the surface of the air inlet pipe, an exhaust pipe is connected to the bottom of the dehydration tower, an air equalizing plate is welded to the inner wall of the dehydration tower, and a round rod is welded to the outer wall of the dehydration tower.

[0009] Further preferably, the front side of the dehydration tower is provided with an opening, and an arc-shaped slide is provided at the opening, and the first arc-shaped plate and the second arc-shaped plate are arranged at the opening of the dehydration tower.

[0010] Further preferably, the fixing frame and the inner wall of the dehydration tower are welded.

[0011] Further preferably, the bevel gear is connected to the fixing frame via a rotating shaft.

[0012] Further preferably, the dehydration components are provided in two groups, and the two groups of components are arranged in parallel structure.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the utility model, the storage box and the adsorbent of the dehydration component can be fixed by the meshing of the bevel gear and the bevel rack. The rotating shaft and the bevel gear can rotate along the fixed frame through the connection of the bearing. When the bevel rack completely slides into the inside of the fixed frame, the connection between the storage box and the fixed frame is tighter through the meshing of the bevel gear, and it will not shake up and down easily. When the adsorbent needs to be replaced, it only needs to slide the storage box outward to drive the storage box and the bevel rack to disengage from the bevel gear, and the disassembly process is faster and simpler.

[0015] In the utility model, a first curved plate and a second curved plate are added to the front of the dehydration tower. When the first curved plate and the second curved plate are completely stored, the second curved plate is slid and stored into the first curved plate. The first curved plate is slid again to drive the second curved plate to slide and be stored into the dehydration tower. At this time, the entire opening is fully exposed, and there is no need to disassemble the dehydration components layer by layer. The dehydration components of a certain layer in the dehydration tower can be disassembled and replaced separately. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 4 The utility model provides a technical solution: a quick-detachable dehydration device, including a dehydration tower 1, a first arc plate 2 is slidably connected to the front of the dehydration tower 1, a second arc plate 3 is slidably connected inside the first arc plate 2, a clamping block 4 is rotatably connected to the front of the second arc plate 3, and a dehydration component 5 is installed inside the dehydration tower 1.

[0023] The dehydration assembly 5 includes a fixed frame 501, which is slidably connected to a bevel rack 502 inside. A bevel gear 503 is meshed on one side of the bevel rack 502. A storage box 504 is welded to the top of the bevel rack 502. An adsorbent 505 is provided inside the storage box 504. A rotating shaft 506 is inserted into the inside of the bevel gear 503.

[0024] In this embodiment, Figure 1 and Figure 3 As shown, an air inlet pipe 101 is connected to the top of the dehydration tower 1, a valve 102 is installed on the surface of the air inlet pipe 101, an exhaust pipe 103 is connected to the bottom of the dehydration tower 1, an air equalizing plate 104 is welded to the inner wall of the dehydration tower 1, and a round rod 105 is welded to the outer wall of the dehydration tower 1; it should be noted that valves 102 are installed on the surfaces of the air inlet pipe 101 and the exhaust pipe 103. After opening the valve 102, the natural gas enters the dehydration tower 1 from the air inlet pipe 101, and is homogenized by the air equalizing plate 104. The air equalizing plate 104 can evenly distribute the natural gas entering the dehydration tower 1 to the entire cross-section of the dehydration tower 1, ensuring that the dehydration component 5 below is fully in contact with the natural gas, thereby improving the dehydration efficiency.

[0025] In this embodiment, Figure 2 As shown, the front of the dehydration tower 1 is provided with an opening, and an arc-shaped slide is provided at the opening, and the first arc-shaped plate 2 and the second arc-shaped plate 3 are arranged at the opening of the dehydration tower 1; it should be noted that the width of the opening is just as large as the diameter of the dehydration tower 1, and the first arc-shaped plate 2 and the second arc-shaped plate 3 can both slide along the arc-shaped slide, and the arc-shaped slide plays a limiting role therefor. When the second arc-shaped plate 3 is slid and stored in the first arc-shaped plate 2, the first arc-shaped plate 2 is slid again, driving the second arc-shaped plate 3 to slide and be stored in the dehydration tower 1 together, at this time the entire opening is fully displayed, which is convenient for disassembling the internal dehydration component 5.

[0026] In this embodiment, Figure 4 As shown, the fixing frame 501 and the inner wall of the dehydration tower 1 are welded together; it should be noted that the fixing frame 501 and the inner wall of the dehydration tower 1 are welded together, and the fixing frame 501 is not removable. When the storage box 504 and the bevel rack 502 at the bottom thereof are slid and inserted along the bevel gear 503, the fixing frame 501 supports the entire dehydration assembly 5 to prevent the dehydration assembly 5 from detaching from the fixing frame 501.

[0027] In this embodiment, Figure 4 As shown, the bevel gear 503 is connected to the fixed frame 501 through the rotating shaft 506; it should be noted that the rotating shaft 506 and the fixed frame 501 are plugged in, and a bearing is provided between the two. During the process of the bevel rack 502 meshing and sliding inward along the bevel gear 503, the rotating shaft 506 and the bevel gear 503 can rotate along the fixed frame 501 through the connection of the bearing. When the bevel rack 502 completely slides into the inside of the fixed frame 501, through the meshing of the bevel gear 503, the connection between the storage box 504 and the fixed frame 501 is tighter and will not shake up and down easily.

[0028] In this embodiment, Figure 3 As shown, there are two groups of dehydration components 5, and the two groups of components are set in parallel structure; it should be noted that the adsorbent 505 filled in the storage box 504 of the first layer of dehydration components 5 is composed of multiple layers of mesh activated carbon, and the adsorbent 505 filled in the storage box 504 of the second layer of dehydration components 5 is composed of molecular sieves with a microporous structure. The lower surface of the storage box 504 is provided with a filter screen to facilitate the natural gas to pass through the dehydration component 5 smoothly while being dehydrated. When the first arc plate 2 and the second arc plate 3 are completely stored, the saturated adsorbent 505 inside the two groups of dehydration components 5 can be replaced separately.

[0029] The use method and advantages of the utility model: When the quick-detachable dehydration device is used, the working process is as follows:

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, first, the rotating shaft 506 blocks 4, and the blocks 4 are rotated upward by 90 degrees, so that the blocks 4 are separated from the round rod 105, and the second arc plate 3 is slid to be stored in the first arc plate 2, and then the first arc plate 2 is slid to drive the second arc plate 3 to be stored in the dehydration tower 1, and the storage box 504 is slid. When the storage box 504 slides, the helical rack 502 at the bottom is driven to mesh with the helical gear 503 for transmission, and the helical rack 502 slides outward along the helical gear 503, driving the entire storage box 504 to slide completely to The opening on one side of the dehydration tower 1 and the disengagement of the bevel rack 502 and the bevel gear 503 drive the storage box 504 to quickly detach from the dehydration tower 1, so that the adsorbent 505 in the storage box 504 can be poured out and replaced with a new adsorbent 505, and then the bevel rack 502 at the bottom of the storage box 504 is aligned with the bevel gear 503 and slides inward. When the storage box 504 completely slides into the dehydration tower 1, the meshing of the bevel gear 503 and the bevel rack 502 increases the structural strength and prevents the storage box 504 from shaking in the dehydration tower 1.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
