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 counterflow flue gas purification device of the present invention is as follows: Figure 1 to Figure 6 As shown, the counter-flow 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 arrang...

Abstract

The invention discloses a reverse-flow type flue gas purifying device and purifying units thereof. The reverse-flow type flue gas purifying device comprises at least two vertical purifying units, wherein each purifying unit comprises a purifying tower body, an activated carbon distribution system is arranged at the upper part of the purifying tower body and comprises downwards inclined main distribution pipes, branch distribution pipes with downward openings are arranged on the main distribution pipes, and the openings of all the branch distribution pipes are located in the same horizontal line; vertical discharge pipes are arranged between the main distribution pipes of the purifying tower bodies, discharge ends of the main distribution pipes of the top purifying unit and feed ends of the main distribution pipes of the rest purifying units are connected onto the discharge pipes, discharge systems are arranged at lower parts of the purifying tower bodies, each discharge system comprises a conical discharge hopper and a collection hopper arranged below the conical discharge hopper, and bottoms of the collection hoppers of previous purifying units are connected with discharge pipes fed into the collection hoppers of the next purifying units. The utilization rate of upper space of the purifying units is high, and bottom discharge uniformity is realized.

Description

technical field [0001] The invention relates to a flue gas purification system, in particular to a countercurrent 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 a...
