Embodiment Construction

[0014] Such as figure 1 The shown activated carbon-based catalytic flue gas deep desulfurization device includes a desulfurization tower 1 and a desulfurization box 3. The desulfurization box is connected to one side of the lower end of the desulfurization tower and communicates with it. In the desulfurization box, A rotary desulfurization mechanism is provided, and a desulfurization seat 2 is provided in the desulfurization tower. There are several activated carbon channels 2-1 that penetrate up and down in the desulfurization tower. The desulfurization tower below the desulfurization seat is provided There is a restricted grid plate 4, the activated carbon in the desulfurization seat stays in the activated carbon channel through the restricted grid plate, and a spray pipe 5 is also arranged in the desulfurization tower below the restricted grid plate, and the The desulfurization tower is provided with three spray pipes sequentially from top to bottom, and the top of the desu...

Abstract

The invention relates to an activated carbon-based catalytic flue gas deep desulfurization device, which is characterized in that the device comprises a desulfurization tower and a desulfurization boxbody, the desulfurization box body is connected to one side of the lower end of the desulfurization tower and is communicated with the desulfurization tower, a rotary desulfurization mechanism is arranged in the desulfurization box body, a desulfurization base is arranged in the desulfurization tower, a plurality of activated carbon channels which are through up and down are formed in the desulfurization base, a limiting grid plate is arranged in the desulfurization tower below the desulfurization base, activated carbon in the desulfurization base stays in the activated carbon channels through the limiting grid plate, spraying pipelines are further arranged in the desulfurization tower below the limiting grid plate, the three spraying pipelines are sequentially arranged in the desulfurization tower from top to bottom, and an activated carbon bin is further arranged at the top of the desulfurization tower. The design has the advantages of being simple in structure, easy to manufacture,practical and efficient.

Description

technical field [0001] The invention relates to the technical field of flue gas purification, in particular to an activated carbon-based catalytic flue gas deep desulfurization device. Background technique [0002] Flue gas desulfurization of power plant boiler flue gas and steel mill sintering flue gas mainly includes wet desulfurization and dry desulfurization. Among them, dry desulfurization is mainly based on activated carbon and activated coke catalytic adsorption. Among them, activated carbon has a good desulfurization effect and does not need It consumes a lot of water and does not generate solid waste. However, the problem with this method is that the strength of activated carbon is low, and the existing equipment and technology cannot guarantee its large-scale application in flue gas desulfurization. However, this greatly limits the application of this method in the actual desulfurization process. [0003] In addition, the use of activated carbon for flue gas deni...
