[0027] Embodiment 2: In Embodiment 1, there is still the problem that the existing natural gas mercury removal separator is prone to incomplete mercury removal. Therefore, based on Embodiment 1, this embodiment further includes:

[0028] A mercury content detector 2 is fixedly provided in the air outlet 12, a pair of three-way pipes 21 are fixedly provided at the top and bottom of the box body 1, a fan 22 is fixedly provided on one side of the box body 1, right-angle pipes 23 are fixedly provided on both sides of the fan 22, and the other ends of the right-angle pipes 23 are respectively fixedly connected to the three-way pipes 21, the mercury content detector 2 is located at the center of the air outlet 12, and the three-way pipes 21 correspond to the positions of the air inlet 11 and the air outlet 12 respectively.

[0030] Specifically, the working principle and operation method of the utility model are as follows:

[0031] Step 1: natural gas that has not been demercured is injected into the box body 1 through the top three-way pipe 21 and the air inlet 11. The natural gas in the box body 1 passes through the adsorption plate 18. The adsorption plate 18 adsorbs the mercury in the natural gas. The natural gas completes the demercuration treatment through the adsorption plate 18. The demercured natural gas enters the three-way pipe 21 at the bottom of the box body 1 through the air outlet 12. When passing through the air outlet 12, the mercury content detector 2 detects the mercury content in the natural gas. When the test result meets the standard, it is discharged through the three-way pipe 21. When the test result fails, the fan 22 is started. The fan 22 extracts the natural gas that has not reached the standard through the right-angle pipe 23 and the natural gas in the three-way pipe 21 at the bottom of the box body 1, and injects it into the three-way pipe 21 at the top of the box body 1.

[0032] Step 2: When the adsorption efficiency of the adsorption plate 18 decreases after long-term use, the paddle plate 116 is toggled, and the paddle plate 116 drives the limit block 114 to move into the limit groove 113 to squeeze the spring 115, so that the limit block 114 is disengaged from the right-angle groove 112, and the baffle plate 19 is pulled backward through the pull groove 111. The baffle plate 19 drives the installation frame 16 to move out of the box body 1 through the T-shaped slide bar 15, and the installation frame 16 drives the adsorption plate 18 to move outward. When the adsorption plate 18 moves out of the box body 1, the adsorption plate 18 is lifted upward. 8. Remove it from the installation frame 16, insert a new adsorption plate 18, push the baffle 19, and the baffle 19 drives the installation frame 16 and the adsorption plate 18 to move into the box body 1. The guide wheel 17 makes the T-shaped slide bar 15 move more smoothly, so that the installation frame 16 is inserted into the sealing groove 14, and the limit block 114 is inserted into the right-angle groove 112 to limit the baffle 19. The replacement of the adsorption plate 18 is completed, and the square sealing ring 117 seals the baffle 19 and the box body 1 to prevent natural gas leakage;
