As shown in fig. 3, the first spiral sleeve 41, the second spiral sleeve 51 and the third spiral sleeve 61 are cylinders (i.e. the longitudinal section is n-shaped) with one open end, the inner diameter of the cylinder is the same as the diameter of the flange 11, the bottom of the cylinder is provided with a through hole 611, the diameter of the through hole 611 is larger than the diameter of the cylindrical tube of the adsorption tube 1; the through hole 611 is sleeved outside the adsorption tube 1, and the open end 612 of the cylinder faces to the flange 11 at the end of the adsorption tube and is sleeved on the flange 11; the inner wall of the cylinder body is provided with the internal thread; the diameters of the cylindrical coupling body 62, the air inlet connector 42 and the air outlet connector 52 are the same as the diameter of the flange 11; the screen 2 and the annular gasket 3 are arranged between the cylindrical coupling body 62, the air inlet joint 42 and the air outlet joint 52 and the corresponding end faces of the flange 11.

The mass transfer zone is a term of art for studying adsorbent or catalyst, and is called mass transfer zone, when the mercury-containing natural gas passes through the adsorption tube structure, not every section of adsorption tube can play a demercuration role, for example, the first section can completely adsorb mercury in the natural gas, so that the latter section of adsorption tube can not play a demercuration role any more, and the mass transfer zone or mass transfer zone refers to a section of adsorption tube which plays a demercuration role, and if the mercury-containing natural gas cannot be detected after the first section of adsorption tube, the mass transfer zone of the demercuration agent is short and should be shorter than the length of the first section of adsorption tube.
The demercuration depth refers to a detection value of the mercury content of the natural gas containing mercury after the natural gas passes through the demercuration agent with a certain thickness, if the detection value is higher, the demercuration capability of the demercuration agent is strong, and the demercuration depth is deep, otherwise, if the detection value of the mercury content of the natural gas after demercuration is higher, the demercuration capability of the demercuration agent is weak, and the demercuration depth is shallow.
The demercuration agent is free of mercury at the beginning of use, but during the use process, when natural gas containing mercury flows through the demercuration agent, the mercury in the natural gas is captured by active substances in the demercuration agent, the captured mercury remains on the demercuration agent, and after the demercuration agent is invalid, namely after the demercuration agent no longer has the demercuration capacity, the mercury content of the invalid demercuration agent is detected, and the value is the mercury capacity of the demercuration agent.
In the tower column structure for evaluating the performance of the natural gas mercury removing agent, two adjacent adsorption tubes 1 are connected through the coupling component 6, wherein the cylindrical coupling body 62 can axially rotate relative to the upper adsorption tube and the lower adsorption tube, so that the installation direction of the sampling valve on each cylindrical coupling body 62 can be adjusted to be towards the same direction of the tower column structure by adjusting the position of the cylindrical coupling body 62, and thus, the tower column structure can be conveniently connected with corresponding detection instruments or equipment, and an operator can conveniently observe a plurality of detection instruments.
Further, as shown in fig. 2, in the present embodiment, in order to more accurately position the mounting direction of the sampling valves, the sampling valves are oriented in the same direction of the column structure, and positioning pins 9 are provided between the cylindrical collar body 62 and the corresponding flange 11. One or two positioning pins 9 can be arranged between each flange 11 and the cylindrical coupling body 62; when the tower column structure is assembled, the cylindrical hoop connecting body 62 is positioned firstly, and then the cylindrical hoop connecting body 62 is fixed by the third spiral sleeve bodies 61 on the upper side and the lower side of the cylindrical hoop connecting body 62, so that the sampling valves connected to each cylindrical hoop connecting body 62 can be ensured to face the same direction of the tower column structure.
