Description

Technical Field

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

[0002] Natural gas dehydration refers to the process of removing saturated water vapor from natural gas by certain methods. The natural gas flowing out from the wellhead is usually saturated with gaseous water and may even carry a certain amount of liquid water. The presence of water in natural gas can cause a variety of serious consequences. Therefore, natural gas dehydration is very necessary.

[0003] However, the prior art still has the following problems:

[0004] First, the skid-mounted natural gas dehydration device of the prior art is not easy to lift. Most of the dehydration devices are fixed and can only be moved to the required location and then installed and fixed. However, there are usually many locations where natural gas needs to be processed. If the device can be lifted, it is easy to adjust the position, which can greatly improve the convenience of use.

[0005] Secondly, the skid-mounted natural gas dehydration device in the prior art has a relatively single method for dehydrating natural gas, usually cooling dehydration or absorption and adsorption dehydration. However, after the natural gas is treated by these two methods, some water remains in the natural gas. If they can be used in combination, the water in the natural gas can be removed more effectively.

[0006] In view of the above problems, the inventor proposes a skid-mounted natural gas dehydration device to solve the above problems. Utility Model Content

[0009] Preferably, a connecting pipe is fixedly provided between the upper end of the cooling tower and one side of the outer surface of the adsorption tower, an air outlet pipe is fixedly provided at the upper end of the adsorption tower, and a plurality of adsorption layers are fixedly provided on the inner surface of the adsorption tower. The material of the adsorption layer can be a molecular sieve layer or a silica gel layer, both of which are porous solids. Water is a highly polar molecule with a small molecular diameter. Most porous solids with larger pore sizes can adsorb water. There are five adsorption layers, and the five adsorption layers are evenly spaced up and down.

The bottom plate 1 is a supporting carrier structure. The cooling tower 3 and the adsorption tower 4 on the upper plate 2 constitute a dehydration treatment structure. The device is placed on the ground through the support legs 112. When the position of the device needs to be adjusted, the motor 14 on the guard plate 13 is started to rotate the screw rod 15, thereby driving the lifting block 12 to move up and down. The lifting block 12 moves up and down to drive the vertical plate 11 to move up and down in the through groove 111. During the continuous downward movement of the vertical plate 11, the height of the support plate 16 gradually becomes lower than the support legs 112, and the anti-skid plate 17 contacts the ground. The friction force of the lower surface of the anti-skid plate 17 is relatively large, so that the device is placed more stably, thereby lifting the device to complete the positioning and placement, so that the device is easy to lift, which is convenient for fine-tuning the position and can be transported. It is relatively stable after being placed, which greatly improves the convenience of natural gas dehydration treatment and has high versatility.

[0020] A control panel 5 is fixedly provided on one side of the upper end of the base plate 1. The control panel 5 is electrically connected to the cooling tower 3 and the motor 14. Through control by the control panel 5, the cooling degree of the cooling tower 3 can be adjusted according to the situation of the natural gas. The output of the motor 14 can also be controlled to adjust whether the device is in a placed state or a mobile state.

[0021] Both ends of the vertical plate 11 are movably contacted with fixed blocks 19, and two through-type bolt grooves 110 are provided at both ends of the vertical plate 11, and bolts are movably inserted between the bolt grooves 110 and the corresponding two fixed blocks 19. After the vertical plate 11 rises or falls, the bolts are inserted into the two fixed blocks 19 and the corresponding bolt grooves 110 to complete the fixation, thereby improving the stability of the support of the vertical plate 11, thereby improving the firmness of the device when it is placed.

[0022] Embodiment 2: Figure 1-3 As shown, a connecting pipe 31 is fixedly provided between the upper end of the cooling tower 3 and one side of the outer surface of the adsorption tower 4, an outlet pipe 41 is fixedly provided at the upper end of the adsorption tower 4, and a plurality of adsorption layers 42 are fixedly provided on the inner surface of the adsorption tower 4, and five adsorption layers 42 are provided, and the five adsorption layers 42 are evenly spaced up and down.

The double dehydration treatment of first cooling and dehydration and then adsorption and dehydration is adopted, thereby improving the dehydration effect of the skid-mounted natural gas, so that the obtained skid-mounted natural gas has a higher purity.

[0023] Working principle: the bottom plate 1 is a supporting carrier structure, and the cooling tower 3 and the adsorption tower 4 on the upper plate 2 constitute a dehydration treatment structure. The device is placed on the ground through the support legs 112. When the position of the device needs to be adjusted, the motor 14 on the guard plate 13 is started to rotate the screw rod 15, thereby driving the lifting block 12 to move up and down. The lifting block 12 moves up and down to drive the vertical plate 11 to move up and down in the through groove 111. During the continuous downward movement of the vertical plate 11, the height of the support plate 16 gradually becomes lower than the support legs 112, and the anti-skid plate 17 contacts the ground. The friction force of the lower surface of the anti-skid plate 17 is large, so that the device is placed more stably, so that the device is lifted and the positioning is completed, so that the device is easy to lift, which is convenient for fine-tuning the position and can be transported. It is relatively stable after being placed, which greatly improves the convenience of natural gas dehydration treatment and has high versatility.

[0024] Through the control panel 5, the cooling degree of the cooling tower 3 can be adjusted according to the natural gas situation, and the output of the motor 14 can be controlled to adjust whether the device is in a placed state or a mobile state;

[0025] After the vertical plate 11 is raised or lowered, the bolts are inserted into the two fixing blocks 19 and the corresponding bolt slots 110 to complete the fixing, thereby improving the stability of the support of the vertical plate 11 and thus improving the firmness of the device when placed;

[0026] After the skid-mounted natural gas is cooled by the cooling tower 3 to remove part of the water, it flows into the adsorption tower 4 through the connecting pipe 31, is adsorbed by the multi-layer adsorption layer 42, and is finally discharged through the outlet pipe 41 and collected at the outlet pipe 41. The double dehydration treatment of first cooling and dehydration and then adsorption and dehydration is adopted, thereby improving the dehydration effect of the skid-mounted natural gas and making the obtained skid-mounted natural gas higher in purity.
