Abstract

The invention discloses a flue gas white smoke removal device, which comprises a desulfurization box, a thermostat is fixedly installed outside the desulfurization box, a fixed frame is installed on one side of the desulfurization box, a flue gas dredging channel is installed in the fixed frame, and one end of the flue gas dredging channel is fixedly connected with one side of the desulfurizationbox, the other end of the flue gas dredging channel is fixedly connected with the side, fixedly connected with the heat exchanger, of the bottom end of the heat exchanger, a cooler is fixedly installed at the top of the heat exchanger, and one side of the cooler is fixedly connected with one end of the conveying pipeline. In this scheme, after the industrial flue gas is desulfurized by the installed desulfurization box, the white smoke is filtered again through the filter, a heater is installed in the chimney, mixed flue gas becomes unsaturated flue gas, the white smoke cannot be generated inthe output chimney, the white smoke removal efficiency of the chimney is improved, and the pipeline is prevented from being blocked.

Description

technical field [0001] The invention belongs to the technical field of flue gas purification, and in particular relates to a flue gas whitening device. Background technique [0002] The flue gas produced by many production processes of iron and steel enterprises has a high moisture content. For example, after wet desulfurization of sintering flue gas, the water vapor in the flue gas increases greatly, and the flue gas gradually reaches saturation. The amount of water vapor that can be carried by saturated flue gas at 45-55°C is 120g / kg of dry flue gas. kg of dry flue gas, the ability to carry water vapor per unit volume of flue gas is reduced by 85%. Therefore, a large amount of water vapor in the flue gas is precipitated to form tiny water droplets, which appear as white plumes under visible light and sunlight. [0003] The traditional initial high-temperature flue gas is used as the heat exchange medium of the heat exchanger to heat the flue gas, but usually the dew point...
