DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0023] like Figure 1-Figure 2As shown, this embodiment provides a natural gas high-efficiency wellhead decarbonization tower, which is installed in a natural gas wellhead transportation device containing carbon dioxide. The decarbonization tower includes a tower body 1 and a tower internal component 2 arranged in the tower body 1. When the natural gas containing carbon dioxide passes through the natural gas wellhead transportation device, the tower internal component 2 can effectively absorb carbon dioxide without affecting the normal transportation of natural gas, thereby effectively preventing carbon dioxide from forming acid damage to subsequent pipelines and equipment.

[0024] Specifically, the tower body 1 includes a first tower body section 11 and a second tower body section 12 disposed at the upper end of the first tower body section 11. The first tower body section 11 and the second tower body section 12 are connected by a flange 13 to facilitate the maintenance and replacement of the tower internal component 2. The tower internal component 2 includes a packing 21, a distributor 22, and a cyclone 23 disposed in the tower body 1 from top to bottom along the axis of the tower body 1. The distributor 22 includes an upper distributor 221 and a lower distributor 222. The packing 22 is provided in three groups and is arranged in an array between the upper distributor 221 and the lower distributor 222; Figure 2-Figure 3 As shown, the output end of the cyclone 23 is provided with fan-shaped blades in a circular array along the shell of the cyclone 23. The cyclone 23 includes an upper cyclone 231 and a lower cyclone 232. The upper cyclone 231 is provided on a side of the upper distributor 221 away from the packing 22, and the lower cyclone 232 is provided on a side of the lower distributor 222 away from the packing 22.

[0025] Specifically, the tower body 1 is connected with a natural gas inlet, a natural gas outlet, a backwash port, and a transmitter port. The first tower body section 11 and the second tower body section 12 are respectively provided with transmitter ports. The first tower body section 11 is connected to the natural gas inlet, and the second tower body section 12 is connected to the natural gas outlet. A cone end 111 is provided at the lower end of the first tower body section 11, and an elbow 112 is provided at one end of the cone end 111. A sewage outlet is provided at one end of the elbow 112. When the tower body 1 needs to be flushed, a pressure difference of 0.5 MPa to 1.0 MPa occurs between the cyclone 23 and the tower body 1 and the packing 21. The decarbonization tower flushing process is run, and the backwashing valve is opened to flush with high-pressure natural gas. After the natural gas flushing is completed, the impurities and water mixture deposited at the bottom of the first tower body section 11 are flushed with clean water after the pressure is released through the venting pipeline, and then discharged from the first tower body section 11 through the sewage outlet; the cone end 111 at the bottom of the first tower body section 11 should be arranged to ensure that impurities are not deposited at the bottom of the first tower body section 11.

[0026] The cyclone 23 and the filler 21 are provided with supporting members for connecting to the inner wall of the tower body 1, and the upper part thereof is provided with a bolt seat for connecting to the natural gas outlet. The cyclone 23 and the filler 21 are processed by wire cutting to intercept the regular plate contact mode, and are equipped with an axial positioning device to increase the residence time of the natural gas in the tower body 1, so as to achieve a better removal effect of carbon dioxide.

[0027] Specifically, the packing 21 includes a regular plate packing 211 and a wire mesh packing 212 arranged on the regular plate packing 211, the lower diverter 221 is arranged below the regular plate packing 211 of the lowest group of packings 21, and the upper diverter 222 is arranged above the wire mesh packing 212 of the highest group of packings 21, and the regular plate packing 211 is provided with a reagent. The natural gas passes through the cyclone 23 and the annular space of the regular plate packing 211 to effectively bring the reagent into contact with the natural gas, thereby further removing carbon dioxide in the natural gas, thereby improving the purity of the natural gas.

[0028] Preferably, the overall height of the tower body 1 does not exceed 3.5 meters, which is convenient for skid mounting and transportation of the equipment.

[0029] The above are only preferred embodiments of the present invention, and are not intended to be the only or limiting embodiments of the present invention. Those skilled in the art should understand that various changes or equivalent replacements made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
