Wet desulphurization tail smoke white removing tower and application

Abstract

The invention relates to a wet desulphurization tail smoke white removing tower. The white removing tower comprises a tower body, a water outlet, an inlet smoke channel, flow homogenizing devices, condensation sections, a draught fan, a demisting section, an inner cylinder and a top outlet, the water outlet is coaxially communicated with the bottom of the tower body, the top outlet is coaxially communicated with the top of the tower body, the flow homogenizing devices are coaxially arranged on the part, above the water outlet, of the tower body at intervals, the condensation sections are coaxially arranged on the part, above the flow homogenizing devices, of the tower body at intervals, the outer sides of the lower bottom faces of the condensation sections are tightly connected with the inner wall of the tower body through a sealing plate, and the inner cylinder is coaxially arranged in the part, between the condensation sections and the top outlet, of the tower body. The white removing tower can reduce the water content in the smoke and the smoke temperature after wet desulphurization, so that no white smoke plume capable of being recognized by naked eyes does not exist in the smoke exhausted into the air, the investment and the operation maintenance of the white removing system are greatly reduced, the benefits are improved, and the purposes of energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention belongs to the technical fields of chemical industry and environmental protection, in particular to a wet-process desulfurization tail flue gas whitening tower and application. Background technique [0002] The flue gas discharged after wet desulfurization carries a large amount of water vapor, and the wet flue gas enters the ambient atmosphere with a lower temperature, causing a lot of waste of water resources, and will also form the phenomenon of "white smoke", resulting in visual pollution and bringing Huge public opinion pressure. At present, more than 85% of domestic coal-fired power plants and iron and steel sintering use wet desulfurization technology, and the temperature of the discharged wet flue gas is 45°C to 55°C, and the moisture content is nearly saturated. [0003] The widely used wet flue gas whitening technology is the flue gas cooling and reheating whitening technology. This technology is mainly composed of three-stage...
