Structure principle and application scope of flue gas desulfurization tower
Flue gas desulfurization tower structure principle and application scope I. Flue gas desulfurization tower structure principle The flue gas desulfurization tower adopts the principles of inertial collision, condensation, centrifugal force, etc. Under the action of the induced draft fan, the flue gas falls from a certain height and impacts the liquid surface at high speed. Water mist forms. Most of the particles sink into the water. Under the action of the dust collector diverter, the atomized airflow rises rapidly, and the droplets further collide and condense to form a water-ash mixture. The water-ash mixture is separated by steam and water through the cyclone impeller, thereby completely To achieve its desulfurization-dust removal-dehydration effect. Structural principle of flue gas desulfurization tower: The flue gas containing soot and sulfur oxides enters the cylinder through the inlet flue, and the alkaline absorption liquid containing [OH-] ions is sprayed from the upper and lower parts of the filter dust removal desulfurization tower by spiral nozzles The formation of multiple rows of high-speed atomized water curtains in reverse to the smoke increases the collision probability of smoke and sulfur oxides with water, and makes full use of the speed of the atomized droplets to create a high relative gas-liquid velocity to ensure dust removal. Dust removal and desulfurization effect. At the same time, when the gas passes through the sieve plate, it produces a bubbling effect on the liquid layer on the sieve plate, which increases the surface area and turbulence of gas-liquid mass transfer, increases the mass transfer rate, and causes gas-liquid mass transfer between sulfur dioxide and alkaline solution, thereby further improving The effect of desulfurization and dust collector. The desulfurization product flows with the water to the bottom of the desulfurization tower and is drained from the overflow hole. A water seal groove is provided at the bottom of the cylinder to prevent leakage of flue gas from the bottom. A cleaning hole is also provided to facilitate the manual cleaning of the ash at the bottom of the cylinder (also Can be automatically cleaned). The desulfurization wastewater is discharged into the sedimentation tank through the bottom overflow hole, and the precipitate is neutralized and regenerated, and recycled (double alkali method). The purified gas is discharged through the upper part of the cylinder through the demister, thereby achieving the purpose of dust removal and desulfurization.
Scope of application of flue gas desulfurization tower The flue gas desulfurization tower is a purification device designed for industrial welding fume and light particles. It is lightweight, flexible, and easy to operate. It is also widely used in chemical, electronics, metal processing, and tobacco. , Glass, pharmaceutical, food processing, clean room, hospital and other industries and other places polluted by dust and smoke. At the same time, it is also suitable for arc welding, CO2 shielded welding, MAG shielded welding, special welding, gas fusion cutting and other welding and polishing of carbon steel, stainless steel, aluminum and other metals.
