SEMI-DRY FLUE GAS DE-SULFURIZATION APPARATUS AND CIRCULATING FLUIDIZED BED COMBUSTION DEVICE

摘要

PURPOSE: A semi-dry de-sulfurizing apparatus and a hybrid dust collecting facility for a circulation fluidized bed combustion device equipped with the same are provided to improve the mixing force of combustion gas and a solvent by generating the combustion gas and guiding the combustion gas to a solvent injecting nozzle. CONSTITUTION: A semi-dry de-sulfurizing apparatus(300) includes a casing(310) and a solvent spraying nozzle(320). A combustion gas inlet(311), a de-sulfurized material outlet(316), and a processing gas outlet(317) are formed at the casing. The solvent spraying nozzle is formed at one side of the casing. The solvent spraying nozzle sprays a solvent to combustion gas. The combustion gas inlet includes an introduction port(312), an introduction expanding port(313), and an introduction bending port(314). The introduction port is formed on the peripheral side of the casing. The introduction expanding port is expanded from the introduction port to the inside of the casing. The introduction bending port is bent toward the solvent spraying nozzle from the introduction expanding port. A vortex wing(315) is formed at the introduction bending port.
