DETAILED DESCRIPTION

[0041] Please refer to Figures 1-7 , the utility model provides a natural gas desulfurization device, include: horizontal tank 1, liquid level assembly 2, pretreatment zone 3, post-treatment zone 4, pretreatment assembly 5 and flash tower 7;

[0042] The liquid level assembly 2 is arranged at the middle position inside the horizontal tank 1, and divides the horizontal tank 1 into the pre-treatment area 3 and the post-treatment area 4.

[0043] The pre-treatment assembly 5 is arranged at the top end of the horizontal tank 1 at the pre-treatment area 3, and the flash tower 7 is arranged at the top end of the horizontal tank 1 at the post-treatment area 4.

[0044] Further, the horizontal tank 1 is provided with a second discharge port 8 at the bottom end at the post-treatment area 4, and the horizontal tank 1 is provided with a driving assembly 6 on the outer wall at the top end at the pre-treatment area 3.

[0045] In the embodiment, as shown in Figure 1 The natural gas in the gas-liquid mixed state is first pre-treated by the pre-treatment assembly 5, and then enters the pre-treatment area 3 in the horizontal tank 1 to perform the first-stage gas-liquid separation. Then, the natural gas in the gas-liquid mixed state flows through the post-treatment area 4 in the horizontal tank 1 to perform the second-stage gas-liquid separation. Finally, the post-treatment area 4 enters the flash tower 7 to perform the last absorption of hydrogen sulfide, and the pure natural gas is discharged. The liquid in the post-treatment area 4 is discharged to the outside of the horizontal tank 1 through the second discharge port 8.

[0046] Further, the pre-treatment assembly 5 comprises a barrel 51, a plurality of outer ring holes 52, and a plurality of flow guide covers 53.

[0047] The barrel 51 is rotatably penetrated through the top end of the horizontal tank 1, and the middle part of the barrel 51 is a cavity.

[0048] A plurality of outer ring holes 52 are arranged at the circumferential position of the middle part of the barrel 51, and the plurality of outer ring holes 52 form a group of outer ring holes. A plurality of groups of outer ring holes are equidistantly arranged along the axial direction of the barrel 51. A plurality of flow guide covers 53 are arranged on the outer wall of the barrel 51 and staggered with the plurality of groups of outer ring holes.

[0049] Further, the pre-treatment assembly 5 further comprises a ring groove 54, an inner barrel 55, a ring block 56, and an inner ring hole 57.

[0050] One end of the inner barrel 55 is connected to the inner wall of the horizontal tank 1 through a support, and the other end is penetrated through the barrel 51 to the outside and connected to an external feeding mechanism. The ring block 56 is arranged on the outer wall of the inner barrel 55, and the barrel 51 is rotatably connected to the ring block 56 through the ring groove 54.

[0051] The inner cylinder 55 is provided with a plurality of inner ring holes 57 at the cavity position of the cylinder body 51, and the inner cylinder 55 is provided with a plurality of groups of inner ring holes along the axial direction at the cavity position of the cylinder body 51.

[0052] In the embodiment, as shown in Figure 1 and Figure 2 The bracket connected with the inner cylinder 55 is indicated by a dashed line at the pretreatment assembly 5 position, which can be a rod, a plate or a frame, as long as it can complete the structural connection relationship in the utility model.

[0053] Further, the cylinder body 51 is provided with a plurality of groups of guide plates 58 on the inner wall at the cavity position, and the number of the plurality of groups of guide plates 58 corresponds to the number of the plurality of outer ring holes 52 in the same group of outer ring hole groups.

[0054] Further, each of the outer ring holes 52, each of the inner ring holes 57 and each of the groups of guide plates 58 is arranged obliquely, the arrangement direction of each of the outer ring holes 52 is opposite to that of each of the inner ring holes 57, and the arrangement direction of each of the outer ring holes 52 is the same as that of each of the groups of guide plates 58.

[0055] In the embodiment, the utility model can realize pretreatment operation before the mixed gas enters the horizontal tank 1, and the pretreatment operation refers to preliminary separation of the mixed gas, and the preliminary separation in the utility model is completed by the collision action. The utility model can complete the collision action in the process of continuous flow of the mixed gas under the premise of meeting the existing uniform and uniform dispersed tank entering state, and improve the purity of the collected natural gas.

[0056] As a preferred embodiment, please refer to Figure 3 and Figure 4 The natural gas in a gas-liquid mixed state (hereinafter referred to as mixed gas) is supplied by an external feeding mechanism, which first enters the inner cylinder 55. Figure 4 For example, at this time, the inclination direction of the plurality of outer ring holes 52 is the clockwise direction, the inclination direction of the plurality of inner ring holes 57 is the counterclockwise direction, and the inclination direction of the plurality of groups of guide plates 58 is the clockwise direction.

[0057] The driving assembly 6 drives the cylinder body 51 to rotate in the clockwise direction (as indicated by the outer ring arrow in Figure 4 ), and the mixed gas entering the inner cylinder 55 will flow out along the inclination direction of the plurality of groups of inner ring holes (the overall flow direction is counterclockwise, as shown in Figure 4(As indicated by the inner circle arrow) and enters the pretreatment space between the outer wall of the cylinder 51 and the inner cylinder 55. Upon entering the pretreatment space, the mixed gas will initially flow in a regular counter-clockwise, approximately circular direction, with the radius of this approximately circular flow (which essentially refers to the size of the loop formed by the approximately circular flow) gradually increasing. When the mixed gas contacts the multiple sets of guide plates 58 on the inner wall of the clockwise rotating cylinder 51, the guide plates 58 will meet and strike the mixed gas flowing counter-clockwise; this is the first collision action. The struck mixed gas will then turn around and flow out through multiple outer ring holes 52, and subsequently, under the guidance of various flow guides 53, it will enter the pretreatment zone 3 within the horizontal tank 1 in a uniformly dispersed state.

[0058] It is important to note that before entering each outer ring hole 52, the mixed gas will meander between the guide plates 58 located on both sides of the same outer ring hole 52. During this meandering process, it will make contact with the guide plates 58 multiple times, which is the second collision action. Combining the two collision actions, an efficient pretreatment operation of the mixed gas can be achieved, improving the purity of the natural gas subsequently collected.

[0059] In this embodiment, the inclination direction of each outer ring hole 52 is opposite to that of each inner ring hole 57. Essentially, this means that the flow direction of the gas mixture exiting each outer ring hole 52 is opposite to the flow direction of the gas mixture exiting each inner ring hole 57. Specifically, it is still based on... Figure 4 For example, the flow direction of the outer ring arrow is opposite to that of the inner ring arrow, that is, the setting tilt direction of each outer ring hole 52 is opposite to that of each inner ring hole 57.

[0060] In this embodiment, the outer ring hole 52 and each group of guide plates 58 are inclined in the same direction, which essentially means that... Figure 4 From the viewpoint shown, the tilt direction of each set of guide plates 58 is consistent with the axis of each outer ring hole 52 (e.g., Figure 4 (As shown by the line drawn at the midpoint).

[0061] As a preferred embodiment, the oblique arrangement of each outer ring hole 52, each inner ring hole 57, and each group of guide plates 58 in this utility model can also be as follows: Figure 7 The type shown. At this time, the drive component 6 needs to drive the cylinder 51 to rotate counterclockwise so that the guide plates 58 can perform the first and second collision actions on the mixed gas flowing clockwise in the pretreatment space.

[0062] Furthermore, the liquid level assembly 2 includes: a low plate 21, a high plate 22, a first outlet 23, and a collection plate 24;

[0063] The low plate 21 and the high plate 22 are both located at the bottom of the center of the horizontal tank 1, and a discharge channel is formed between them.

[0064] The discharge flow channel is provided with the collecting plate 24, and the first discharge port 23 is arranged at the position of the discharge flow channel at the bottom end of the horizontal tank 1.

[0065] As a preferred embodiment, please refer to Figure 1 and Figure 2 The liquid level assembly 2 is arranged to divide the horizontal tank 1 into zones. The liquid level accumulated in the lower part of the pre-treatment zone 3 will gradually rise. When the liquid level rises to the upper limit of the height of the low plate 21, the liquid will enter the discharge flow channel and be discharged to the outside of the horizontal tank 1 through the first discharge port 23 after the finishing treatment of the collecting plate 24.

[0066] It should be noted that in the above process, the medium after the pre-treatment zone 3 is still mixed gas, not completely pure natural gas. The mixed gas will enter the post-treatment zone 4, and the liquid level in the lower part of the post-treatment zone 4 will also gradually rise. When the liquid level is about to rise to the upper limit of the height of the high plate 22, the second discharge port 8 is opened to discharge the liquid to the outside of the horizontal tank 1.

[0067] As a preferred embodiment, the utility model also has another discharge mode for the liquid in the post-treatment zone 4, that is, the second discharge port 8 is cancelled. When the liquid level in the post-treatment zone 4 reaches the upper limit of the height of the high plate 22, it will still enter the discharge flow channel and be discharged to the outside of the horizontal tank 1 through the first discharge port 23 after the finishing treatment of the collecting plate 24. However, it should be noted that the content of hydrogen sulfide absorbed in the discharged liquid from the pre-treatment zone 3 is different from the content of hydrogen sulfide absorbed in the discharged liquid from the post-treatment zone 4. Therefore, whether the other discharge mode for the liquid in the post-treatment zone 4 of the utility model can be used needs to be selected according to the specific situation.

[0068] It should be noted that the finishing treatment operation of the collecting plate 24 on the discharged liquid is a conventional means in the art, which will not be described here. The utility model can also flexibly replace the type of the collecting plate 24 according to the type of the finishing treatment operation to be made.

[0069] Further, the flash tower 7 comprises a tower body 71, a pushing part 72, a flow cavity assembly 73 and an exhaust port 74.

[0070] The tower body 71 is provided with the exhaust port 74 at the top end, and the pushing part 72 is arranged in the tower body 71. A plurality of groups of communication channels are uniformly arranged on the pushing part 72, and the flow cavity assembly 73 is connected to the end of the pushing part 72 away from the exhaust port 74 through a plurality of pushing pieces 721.

[0071] The plurality of pushing pieces 721 and the plurality of groups of communication channels are arranged in a staggered manner.

[0072] Further, the flow cavity assembly 73 comprises: a filler body 731, a pushing rod 732, a vertical pipe 733, a connecting rod 734, a torsion spring 735 and a roller 736.

[0073] The filler body 731 is arranged on the inner wall of the tower body 71, and a plurality of groups of pushing cavities are uniformly arranged on the filler body 731; the pushing cavities are in communication with the plurality of groups of vertical pipes 733 at one end away from the pushing part 72; the vertical pipes 733 are in communication with the inside of the tower body 71 at one end away from the pushing cavities; and the pipe diameter of the vertical pipe 733 is greater than that of the pushing cavity.

[0074] The pushing rod 732 is arranged at one end away from the pushing part 72 of each group of pushing members 721; the rod diameter of the pushing rod 732 at both ends is greater than that of the middle part; a plurality of groups of connecting rods 734 are arranged at the middle part of the pushing rod 732; the torsion spring 735 is arranged at the rotating part; and the roller 736 is arranged at one end away from the pushing rod 732 of each group of connecting rods 734.

[0075] The outer wall of the pushing rod 732 at both ends is in sliding contact with the inner wall of the pushing cavity.

[0076] In the embodiment, the natural gas in the flash tower 7 can be in long-time and sufficient contact with the filler body 731, so that the hydrogen sulfide contained in the natural gas can be completely absorbed, and the natural gas can be completely pure and clean. Figure 5 Figure 6

[0077] As a preferred embodiment, the medium entering the tower body 71 is natural gas after gas-liquid separation (hereinafter referred to as separated natural gas), and the separated natural gas will enter each vertical pipe 733 uniformly; at this time, each pushing member 721 drives the pushing rod 732 to move along the axis direction of the vertical pipe 733 and the pushing cavity.

[0078] First, the pushing rod 732 moves downward; due to the arrangement of the pipe diameter, the rod diameter and the position relationship between the pushing rod 732 and the pushing cavity, the separated natural gas in the vertical pipe 733 will flow to each group of connecting rods 734 along the direction of the arrow as shown in Figure 5 Subsequently, the pushing rod 732 starts to move upward and drives the separated natural gas to enter the absorption space between the pushing rod 732 and the filler body 731 (as shown in B of Figure 5 During the upward movement of the pushing rod 732, the separated natural gas will be in long-time and sufficient contact with the filler body 731, so that the hydrogen sulfide contained in the separated natural gas can be completely absorbed.

[0079] ​​When the advancing rod 732 moves up to its upper end to be disengaged from the advancing cavity, the medium in the absorption space will continue to flow through the flow channels and then be discharged to the exhaust port 74 of the tower body 71, and then be collected by the external gas collecting mechanism. Then the advancing rod 732 needs to move down again to its lower end to be disengaged from the advancing cavity, at this time the subsequent separated natural gas can enter the absorption space to absorb hydrogen sulfide, and so on, so that all the separated natural gas is subjected to the final hydrogen sulfide absorption operation.

[0080] It should be noted that the utility model further provides a plurality of rotatable connecting rods 734 arranged on the outer wall of the middle part of the advancing rod 732, and the opening degree of each group of connecting rods 734 in the initial position is larger than the space of the advancing cavity. Therefore, during the movement of the advancing rod 732, when each group of connecting rods 734 enters the advancing cavity, the advancing cavity will drive the rotation of the connecting rod 734 by means of the roller 736 (as shown by the arrow direction in the middle part), and by means of the action of the torsional spring 735, when each group of connecting rods 734 leaves the advancing cavity, the connecting rod 734 is reset. Figure 6

[0081] It should be noted that the utility model provides a plurality of connecting rods 734, which can disturb the separated natural gas in the absorption space during the movement of the advancing rod 732, so as to enhance the contact degree with the filler body 731, and play an auxiliary role for the complete absorption of hydrogen sulfide.

[0082] It should be noted that since the rotation degree of the connecting rod 734 in the utility model is very small, the rotation of the connecting rod 734 can be realized whether the advancing rod 732 moves up or down.

[0083] Further, the driving assembly 6 comprises a support body 61, a motor 62, a gear 63 and a gear ring 64.

[0084] The motor 62 is arranged on the horizontal tank 1 through the support body 61, the output end of the motor 62 is connected with the gear 63 arranged on the horizontal tank 1 through a rotating shaft, and the outer wall of the upper end of the cylinder body 51 located at the outer position of the horizontal tank 1 is provided with the gear ring 64 engaged with the gear 63.

[0085] In the embodiment, the motor 62 drives the gear 63 to rotate forward or reverse, and drives the cylinder body 51 to rotate forward or reverse through the gear ring 64, so that the pretreatment operation in the utility model can be realized.

[0086] ​In the embodiment, the natural gas in the gas-liquid mixed state is first pretreated by the pretreatment assembly 5, and then enters the front treatment zone 3 in the horizontal tank 1 to perform the first-stage gas-liquid separation. Then the natural gas in the gas-liquid mixed state flows through the rear treatment zone 4 in the horizontal tank 1 to perform the second-stage gas-liquid separation. Finally, the natural gas enters the flash tower 7 from the rear treatment zone 4 to perform the final absorption of hydrogen sulfide, and the pure natural gas is discharged. The liquid in the rear treatment zone 4 is discharged to the outside of the horizontal tank 1 through the second discharge port 8.

[0087] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited to this.
