Solid adsorbent tube

The utility model relates to a solid adsorbent tube, which belongs to the technical field of environmental monitoring and comprises a tube body with an air inlet end and an air outlet end, tube caps are respectively sleeved on the air inlet end and the air outlet end, and a first V-shaped spring wire, inert materials, a partition plate and a second V-shaped spring wire are sequentially fixed inside the tube body from the air inlet end to the air outlet end. The space between the first V-shaped spring wire and the inert material is filled with a solid adsorbent which does not chemically react with mercury and is used for desulfurization, the space between the inert material and the partition plate is filled with a solid adsorbent used for adsorbing mercury, and the space between the partition plate and the second V-shaped spring wire is filled with a solid adsorbent which reacts with mercury to generate compounds with striking colors. Small holes only allowing gas to pass through are formed in the partition pl
