Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] The structure of an embodiment of the catalytic bed flue gas purification device of the present invention is as follows Figure 1 to Figure 6 As shown, the catalytic bed flue gas purification device of this embodiment includes three purification units arranged vertically in succession. A storage bin 5 for storing activated carbon raw materials is provided above the top purification unit. The upper part of the storage bin 5 is provided with Feeding mechanism 4, the feeding mechanism 4 adopts a double-spool star feeder 401, and the space between the two valve cores is sealed with an inert gas to realize the feeding of activated carbon, isolate the air, and prevent the leakage of smoke.

[0034] Each purification unit includes a purification tower body 1 respectively. A flue gas inlet chamber 101 and a flue gas outlet chamber 102 are arra...

Abstract

The invention discloses a catalytic bed flue gas purification device and its purification unit. The catalytic bed flue gas purification device includes at least two vertically arranged purification units. system and the catalyst bed located above the ammonia gas distribution system. The upper part of the purification tower body is equipped with an activated carbon distribution system. The distribution system includes a distribution main pipe that is inclined downward. The openings of the purification towers are on the same horizontal line, and there are vertical feeding pipes between the distribution main pipes of each purification tower body. Above, the lower part of the purification tower body is equipped with a discharge system. The discharge system includes a discharge cone and a collection hopper below the discharge cone. The bottom of the collection hopper of the previous purification unit is connected to the next purification unit. The discharge pipe in the collecting hopper.

Description

technical field [0001] The invention relates to a flue gas purification system, in particular to a catalytic bed flue gas purification device using activated carbon for desulfurization and denitrification and a purification unit thereof, belonging to the technical field of air pollutant purification equipment. Background technique [0002] With my SO 2 and NO x Emissions are gradually increasing, and the standards for flue gas emissions are getting higher and higher. At present, wet technology is mostly used in the field of flue gas purification. The wet desulfurization process not only consumes a lot of water resources, but also produces desulfurized gypsum that will cause secondary pollution to the surrounding environment. [0003] Activated carbon flue gas purification technology is a recyclable dry flue gas purification technology. At a temperature of 80-150 ° C, through the adsorption and catalysis of activated carbon, the SO in the flue gas 2 It reacts with water an...
