Self-adaptation type floating ball demister and demisting method thereof

Abstract

The present invention discloses a self-adaptation type floating ball demister and a demisting method thereof. According to the self-adaptation type floating ball demister, multiple layer floating ball demisting units are arranged in the demister housing, the floating ball demisting units are separated through sieve plates, gas flow enters the demister housing from the bottom portion of the demister housing and then enters the floating ball demisting unit through the sieve plate, the accumulated floating balls in the floating ball demisting units present the floating state under the gas flow effect while the rising gas flow contacts the floating balls being in the floating state, the gas flow direction produces deflection under the effects of inertia and baffling flow, the liquid droplets and the solid particles carried in the gas flow are continuously adsorbed and aggregated by the surface of the floating balls, and the liquid droplet-removed and solid particle-removed gas flow is discharged from the top portion of the demister so as to complete the self-adaptation type demisting. According to the present invention, the floating ball adopts the polymer hollow small ball, characteristics of equipment investment reducing, demisting efficiency improving, clogging resistance, easy rinsing, strong working condition adaptability, less investment, and low operation and maintenance cost are provided, and the generation of the wet method desulfurization chimney gypsum rain is effectively reduced.

Description

technical field [0001] The invention relates to a demister, in particular to an adaptive float demister and a demister method thereof. Background technique [0002] Mist eliminators are widely used in processes such as flash demisting, oil and gas separation, and acid mist purification in chemical and environmental fields. The demister used in the flue gas desulfurization system is an impact demister. In the impact demister, the liquid droplets are captured by the target through three mechanisms: inertial collision, direct interception and diffusion. [0003] When the smoke with water enters the demister, due to inertia, the flow direction of the smoke changes, and the liquid droplets carried in the smoke hit the wall under the action of centrifugal force. Under the action of flue gas scouring, the liquid film on the wall is collected at the inflection point connected with the next channel, forming a thicker water curtain and then flowing down the wall. In the folded plate...
