Abstract

The invention discloses a device for testing fogdrop content in smoke gas and a method for testing fogdrop content in smoke gas. The device for testing fogdrop content in smoke gas comprises a fogdrop absorbing bottle, a pitot tube, an acid gas absorbing bottle, a dryer, an intelligent dynamic pressure balance smoke dust sampling pump and a connecting pipe between the fogdrop absorbing bottle and the pitot tube, and a connecting pipe between the pitot tube and the intelligent dynamic pressure balance smoke dust sampling pump. The device applies absorption liquid to absorb fogdrop with all grain diameters in the smoke gas, thus the sampling bias is reduced; through measuring the Mg2+ content in the absorption liquid, the fogdrop content is directly obtained; the fogdrop absorbing bottle is arranged at the head part of the pitot tube, and extended to a smoke flue in measurement to sample; the device and method for testing fogdrop content in smoke gas can absorb the fogdrop in the smoke gas by the absorption liquid, thus the sampling bias is reduced; through measuring the Mg2+ content in the absorption liquid, the fogdrop content is directly obtained; the method and device are convenient and fast.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a device and method for testing the content of droplets in flue gas. Background technique [0002] At present, most coal-fired power plants use flue gas desulfurization technology to control SO 2 Among them, limestone-gypsum wet flue gas desulfurization (WFGD) has become the preferred technology for desulfurization of large thermal power units due to its high denitrification efficiency and mature technology. The process flow is: SO in flue gas 2 Reacts with the spray slurry in the absorption tower, the SO in the flue gas 2 After being removed, the washed flue gas passes through the demister to remove the slurry droplets carried in the flue gas, and then is discharged into the atmosphere through the chimney. [0003] Since the wet flue gas desulfurization system has the requirement of defogging, in the performance assessment of the desulfurization sy...
