The arrangement of the first heat exchange tube 3, the second heat exchange tube 8, the third heat exchange tube 14, and the fourth heat exchange tube 18 is as follows: figure 2 As shown, the i...

Embodiment 2

[0060] The same active coke analysis device as in Example 1 is used for granular active coke analysis, the only difference is that the first heat exchange tube 3, the second heat exchange tube 8, the third heat exchange tube 14, and the fourth heat exchange tube The inner diameter of 18 is Φ60mm.

[0061] Adopt the same step as Example 1 to carry out granular activated coke, after detection, the adsorption sulfur capacity of the obtained regenerated active coke (the SO that every gram of activated coke adsorbs 2 The amount (mg)) is 90% of the newly prepared active coke.

Embodiment 3

[0063] The same active coke analysis device as in Example 1 is used for granular active coke analysis, the only difference is that the first heat exchange tube 3, the second heat exchange tube 8, the third heat exchange tube 14, and the fourth heat exchange tube The inner diameter of 18 is Φ80mm.

[0064] Adopt the same step as Example 1 to carry out granular activated coke, after detection, the adsorption sulfur capacity of the obtained regenerated active coke (the SO that every gram of activated coke adsorbs 2 The amount (mg)) is 95% of the newly prepared active coke.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to an active coke analysis device and its application. Background technique [0002] Sulfur in flue gas from steel mills is recycled and utilized. At present, granular coke flue gas desulfurization technology is mostly used. First, granular activated coke is used to absorb SO in flue gas. 2 Afterwards, the active coke is analyzed and regenerated. The existing active coke analysis device adopts a shell-and-tube structure or a rotary analysis device. Most shell-and-tube structures use active coke to go through the shell side, and the analytic hot flue gas goes through the tube side. Active coke with this structure is incompletely regenerated, SO 2 Incomplete parsing. The rotary analysis device has a small analysis capacity and is a rotating device, so the sealing performance cannot be guaranteed. Contents of the invention [0003] Aiming at the deficiencies in the prior ...
