Abstract

The invention relates to the technical field of activated carbon desulfurization and denitrification, and provides a desorption tower and its heating gas inlet passage, including an inlet buffer chamber arranged between the inlet pipe and the tower wall; the inlet of the inlet buffer chamber Located on the outer wall directly connected to the tower wall of the air inlet buffer chamber; the air inlet buffer chamber is connected with the tower wall of the desorption tower through an equalizing plate, and the equalizing plate is on the air inlet direction of the air inlet The circulation capacity gradually increases from the center to both ends. Compared with the prior art, firstly, it avoids the problem of uneven flow rate caused by the sudden enlargement of the space when the heating gas directly enters the desorption tower from the intake pipe. Second, break the limitations of pipeline layout, reduce technical risks and technical costs. Further, the flow capacity of the equalizer plate in the air inlet direction increases gradually from the center to both ends, so as to avoid the adverse effects caused by the decreasing trend of the flow velocity of the heated gas in the direction of diffusion from the center to the outer ends.

Description

technical field

[0001] The invention relates to the technical field of activated carbon desulfurization and denitrification, in particular to an activated carbon desulfurization and denitrification analysis tower and a heating gas inlet channel thereof. Background technique

[0002] The adsorption tower and the desorption tower are the two main reaction places of activated carbon desulfurization and denitrification technology. The two organically cooperate to complete the adsorption of harmful substances in the exhaust flue gas, as well as the regeneration and activation of activated carbon; SO in 2 , NO X and other harmful gases. Therefore, on the basis of meeting the requirements of flue gas emission, high-concentration SO can be recycled. 2 , while realizing the recycling of activated carbon.

[0003] As we all know, the regeneration and activation technology of activated carbon that has adsorbed harmful substances mainly includes two methods: dosing analysis and heati...
