Problems solved by technology

[0004] The object of the present invention is to provide a vibration-magnetic coupling fluidized bed flue gas desulfurization reactor, which can solve the problems encountered by existing magnetic fluidized bed flue gas desulfurization devices. When the bed material particles are fine, the desulfurization reaction speed is slow, the time is short, and the efficiency is low, and the inner wall of the reactor is easy to foul and affect the continuation of the reaction.

specific Embodiment approach 3

[0013] Specific implementation mode three: combination figure 1 , figure 2 The present embodiment is described. The flue gas inlet 13 of the present embodiment is arranged on the bottom plate of the wind box 8 or on the side wall of the wind box 8 , as required. Other compositions and connections are the same as those in Embodiment 1.

[0014] The working principle is: sulfur-containing flue gas enters the reactor filled with magnetic powder through the air distribution plate 6, and the desulfurizer enters the reactor from above the fluidized bed through the atomizing nozzle. The desulfurizing agent droplets react chemically with SOx in the rising flue gas, and the unreacted desulfurizing agent falls and covers the magnetic particles, forming a desulfurizing agent reaction layer to continue to react with SOx. When the gas velocity or amplitude is large, the magnetic particles and desulfurizer are carried out of the reactor by the flue gas, and enter the separation device 1...

Description

technical field [0001] The invention relates to a fluidized bed flue gas desulfurization reactor, which belongs to the technical field of environmental protection equipment. Background technique [0002] Coal dominates China's energy resources. The coal-based energy structure will be difficult to change for a long time to come. The relatively backward coal production and consumption methods have increased the pressure on environmental protection. Coal consumption is the main cause of soot-type air pollution and the main source of greenhouse gas emissions. Coal-fired flue gas desulfurization is a basic technical countermeasure to protect the atmospheric environment and control the harm of acid rain caused by sulfur dioxide. In particular, domestic thermal power plants, whose coal consumption accounts for more than 42% of the national coal output, are in urgent need of mature flue gas desulfurization technology with independent intellectual property rights and suitable for...
