Abstract

The invention provides a circular moving bed denitration reactor. The circular moving bed denitration reactor comprises a mounting frame, a plurality of circular moving bed plates and a plurality of circular moving bed plates, the circular barrel is fixedly mounted on the mounting frame; the isolation outer cover is fixedly mounted on the circular barrel; and the isolation inner cover is mounted in the isolation outer cover. According to the circular moving bed denitration reactor provided by the invention, the purification layer is filled in the circular barrel, so that a deacidification adsorbent is arranged in front of the catalyst bed, acid gas in flue gas is adsorbed and removed after the flue gas enters the purification cavity, and then the gas is transferred into the catalyst bed for denitration reaction; after the reaction is completed, clean flue gas is collected to the flue gas output port and is sent out of the circular barrel, and part of the purification layer can be replaced for use without stopping according to the change of bed resistance, so that the continuous operation of the system is not influenced.

Description

technical field [0001] The invention relates to the technical field of flue gas destocking, in particular to a circular moving bed denitration reactor and a square moving bed reactor. Background technique [0002] With the continuous development and progress of industrial technology, in the process of industrial production, a large amount of flue gas will be generated, and the flue gas contains a large amount of nitrate components. Timely disposal of out-of-stock flue gas. [0003] In order to prevent excessive NOx pollution from the combustion of coal in the boiler, the coal should be denitrified. Under gas conditions, the catalyst needs to be replaced regularly, and the moving bed denitrification reactor has an absolute advantage. [0004] In the prior art, when the existing moving bed destocking reactor is installed and used, the inside of the reactor is only filled with catalyst, and the acid gas in the flue gas easily passes through the catalyst layer directly, causin...
