Description

Technical Field

[0001] This utility model relates to the field of natural gas decarbonization, and in particular to an adsorption purification device for natural gas decarbonization. Background Technology

[0002] A natural gas decarbonization absorption tower is a device used to remove carbon dioxide from natural gas. Its working principle is that the reaction liquid absorbs carbon dioxide from the natural gas. The interior of the decarbonization absorption tower is generally divided into two parts by a partition plate: the reaction section and the reaction liquid collection section. Traditionally, the top of the partition plate has multiple guide holes to guide the reaction liquid to the bottom of the partition plate. The flow of the reaction liquid reduces the contact area of ​​the gas-liquid contact surface. At the same time, natural gas may enter the bottom of the partition plate through the guide holes, affecting the recycling of the reaction liquid.

[0003] A search of Chinese patents revealed publication number CN222834265U, which discloses a natural gas decarbonization device. The device includes a decarbonization tower body, a decarbonization layer in the lower part of the decarbonization seat, and a decarbonization seat elastically sliding in the upper part of the tower body via a buffer mechanism. A decarbonizing agent storage tank is located in the upper part of the decarbonization seat via a metal filter screen. A discharge port is located at the bottom of the storage tank, penetrating a discharge hole in the side wall of the tower body. A vibration mechanism is located on the lower side of the decarbonization seat. This invention, by providing a discharge port at the bottom of the storage tank and a vibration mechanism on the lower side of the decarbonization seat, allows the decarbonizing agent in the storage tank to be discharged from the tower body when the discharge port is opened and the decarbonization seat is vibrated by the vibration mechanism. This facilitates the discharge and replacement of saturated decarbonizing agent.

[0004] Existing purification devices are inconvenient to maintain. Generally, the tower plates are fixed to the inner wall of the tower with bolts. When the tower plates become blocked, corroded, or damaged and need to be replaced, the tower body or a large number of bolts need to be disassembled. The operation is cumbersome and time-consuming, which increases the downtime of the equipment and affects production efficiency. At the same time, the internal space of the tower is narrow, and the safety of personnel entering for maintenance is low. In order to solve the above problems, we propose an adsorption purification device for natural gas decarbonization. Utility Model Content
