Abstract

The invention discloses an alloy weir-type demister apparatus used for wet method flue gas desulphurization system. The alloy weir-type demister apparatus used for wet method flue gas desulphurizationsystem comprises a primary demister system, a secondary demister system and a flushing system, the primary demister system and the secondary demister system comprises several alloy weir-type demistercomponents, the alloy weir-type demister components are an independent unit structure, the alloy weir-type demister components comprises two alloy demister blades, a frame and a support block, the alloy demister blades are connected with the frame through a plugging mode to form a weir-type demister module, the weir-type demister module is erected on a support beam through the support block, theflushing system is arranged at an upper side and a lower side of the alloy weir-type demister components, and double-face flushing is formed on the demister components.

Description

technical field [0001] The invention relates to an alloy demister device, in particular to an alloy roof type demister device used in a wet flue gas desulfurization system. Background technique [0002] The demister is the key equipment in the absorption tower of the wet flue gas desulfurization system. It is installed on the upper part of the absorption tower. The smoke containing mist flows through the demister device, and the mist is captured by inertial collision, direct interception and Brownian motion. On the blades, they gradually condense into large particles or liquid films, which pass through the blades and are discharged under the push of the airflow, thereby separating the mist entrained by the net smoke. The mist eliminator device is composed of the mist eliminator body and the flushing system, and its performance directly affects the reliable operation of the absorption tower. The structural form of the mist eliminator is divided into tube type, plate type and...
