Abstract

The invention discloses a flue gas semi-dry desulfurization device and method, comprising a shell component, a desulfurization component, a dust removal component, a fan and a sedimentation tank. and extends into the shell, the outlet pipe is fixedly connected with the shell and away from the intake pipe, the desulfurization assembly includes a desulfurization agent tank and a first nozzle, the first nozzle is fixedly connected with the desulfurization agent tank, and extends into the intake pipe, and the fan is connected to the shell. It is fixedly connected and passes through the air intake pipe. The dust removal component includes an air induction pipe and an air pump. The air induction pipe is fixedly connected to the shell, and the air pump and the air induction pipe are fixedly connected. The generated solid particles move outward due to centrifugal force, and are introduced into the sedimentation tank through the air pump downward for precipitation. The pure air is discharged from the air outlet without reheating, thereby reducing the production cost.

Description

technical field [0001] The invention relates to the field of desulfurization equipment, in particular to a flue gas semi-dry desulfurization device and method. Background technique [0002] In the process of thermal power generation, burning coal will produce a large amount of sulfur oxides. These sulfur oxides are easily soluble in water and coexist in the atmosphere with water droplets and dust. It plays a catalytic oxidation role, and forms sulfuric acid mist. In severe cases, soot-type smog events, such as London smog events, or acid rainfall may occur, so the emission of sulfur oxides must be controlled. [0003] Among the currently used technologies, more than 90% of China's thermal power plants and steel mills use the wet lime / limestone-gypsum flue gas desulfurization process. The gas temperature after this process is low and needs to be reheated to discharge. The energy consumption is high, and the energy supply equipment is also frequently maintained, which increas...
