Wet process desulphurization demisting device and wet process desulphurization device

Abstract

The invention discloses a wet process desulphurization demisting device and a wet process desulphurization device, and belongs to the technical field of wet process desulphurization. The wet process desulphurization demisting device provided by the invention comprises at least two layers of parallel pipe rows; the two adjacent layers of pipe rows are in staggered arrangement; each layer of pipe row respectively comprises a plurality of mutually parallel hollow thin pipes and also comprises a cooling medium source; at least partial hollow thin pipes are communicated with the cooling medium source; the cooling medium source is used for providing cooling media for the hollow thin pipes. According to the wet process desulphurization demisting device and the wet process desulphurization device provided by the invention, the cooling media are communicated inside the pipe rows for cooling smoke gas; water vapor in the smoke gas can be condensed by using fine particulate matters and liquid drops as the core, so that the mass of the fine particulate matters and the liquid drops can be increased; the inertia is increased; the catching capability of the demisting device on the fine particulate matters and the liquid drops is improved; the generation of gypsum rain is avoided; the demisting effect is improved. The wet process desulphurization device provided by the invention is provided with the wet process desulphurization demisting device, and has the advantages that the scale formation blockage cannot easily occur; the demisting effect is good.

Description

technical field [0001] The invention relates to the technical field of wet desulfurization, in particular to a wet desulfurization and demisting device and a wet desulfurization device provided with the wet desulfurization and demisting device. Background technique [0002] At present, the wet desulfurization system of coal-fired boilers is prone to generate mist droplets mixed with gypsum during operation, which needs to be captured by demisters. Wet desulfurization generally uses ridge-type demisters and tube-type demisters. The principle is Relying on the inertia and gravity of the slurry droplets in the flue gas, the flue gas is forced to change direction continuously during the movement, so that the flue gas flow can achieve gas-liquid separation under the action of inertial force and centrifugal force, and achieve the purpose of demisting. The currently used mist eliminators have a low ability to capture fine liquid droplets and solid particles. At the same time, with ...

Problems solved by technology

The currently used demisters have a low ability to capture fine liquid droplets and solid particles. At the same time, with the extension of operation time, fouling and clogging may occur, resulting in a decrease in demisting efficiency.
