Embodiment Construction
[0024] See attached picture. The activated coke regeneration exhaust gas treatment device described in this embodiment includes a flue gas heat exchanger 1 , a high temperature bag filter 2 , an alkali washing desulfurization tower 3 , an activated coke adsorption box 6 , a catalytic oxidation box 7 and an SCR denitrification treatment device 8 . The flue gas heat exchanger 1 is provided with a first pipe and a second pipe which are independent of each other. The first pipe is connected to the intake pipe 10 and the high-temperature bag filter 2. The bag filter is a dry dust filter device. The ash hopper is suitable for collecting fine, dry, non-fibrous dust, and the ash hopper can be connected with the smoke particle collection device 11 . The upper end of the high-temperature bag filter 2 is connected to the bottom of the alkali desulfurization tower 3, and a spray pipe is arranged above the side of the alkali desulfurization tower 3, and a sewage pipe 12 is connected to the...

The invention discloses an activated coke regeneration waste gas treatment device. The activated coke regeneration waste gas treatment device comprises a flue gas heat exchanger, a first pipeline anda second pipeline which are independent of each other are arranged in the flue gas heat exchanger, and the first pipeline is connected with a gas inlet pipeline and a high-temperature bag-type dust collector; the upper end of the high-temperature bag-type dust collector is connected with the bottom of an alkali-washing desulfurization tower, and the lower end of the high-temperature bag-type dustcollector is connected with a smoke particle collecting device; the top of the alkali-washing desulfurization tower is sequentially connected with a flue gas condenser and an active coke adsorption box, the active coke adsorption box is connected with a catalytic oxidation box through a second pipeline in the flue gas heat exchanger, and the catalytic oxidation box is connected with an SCR denitration treatment device. According to the invention, active coke regeneration waste gas is treated by adopting a non-combustion method, on the basis of national standards, the emission of smoke dust particles is reduced by more than 90%, the emission of sulfur dioxide is reduced by more than 95%, the emission of nitric oxide is reduced by more than 80%, and white smoke cannot be seen visually.
Description
technical field [0001] The invention relates to the field of active coke regeneration waste gas treatment, in particular to an active coke regeneration waste gas treatment device and method. Background technique [0002] The active coke regeneration waste gas treatment technology currently in use uses three-stage spraying to treat the regeneration waste gas to remove soot particles, sulfur dioxide, nitrogen oxides, etc. in the waste gas. The treated waste gas can reach Emission Standards. However, due to the water spray method, the spray water is also heated during the treatment of high-temperature flue gas, which generates a large amount of steam, and the exhausted flue gas contains a large amount of water, which is then discharged at the exhaust port. A large amount of white mist is generated, and the dust particles contained in the flue gas show a more obvious black smoke against the background of the white mist, which brings a sensory illusion to the residents around th...
