Abstract

The invention relates to the technical field of flue gas emission of a power plant, in particular to a flue gas treatment system. The flue gas treatment system comprises a flue gas generating device,an indirect cooling tower (1), and a flue gas purifying unit and a chimney (6) disposed in the indirect cooling tower. The bottom of the indirect cooling tower comprises an intake structure and a radiator for heating the air at the intake structure to obtain hot air disposed at the intake structure, and the flue gas generating device is disposed outside the indirect cooling tower and is communicated with the flue gas purifying unit, so that the flue gas in the flue gas generating device enters the flue gas purifying unit for purification treatment and a clean flue is obtained, the chimney is communicated with the flue gas purification unit and extends upward along the center line of the indirect cooling tower at least to the throat of the indirect cooling tower, so that the clean flue gasis discharged into the indirect cooling tower via the chimney and discharged under the carriage of the hot air. As the chimney and the flue gas purification unit are arranged in the indirect cooling tower, the flue gas treatment system saves the industrial land and achieves safety discharge of the flue gas.

Description

technical field [0001] The invention relates to the technical field of flue gas discharge in power plants, in particular to a flue gas treatment system. Background technique [0002] At present, indirect air-cooled coal-fired generating units in power plants are accompanied by a large amount of flue gas during operation, and corresponding flue gas treatment systems must be installed to pre-purify and discharge the large amount of flue gas, so that the flue gas discharged into the atmosphere The air meets the national emission standards, thereby reducing environmental pollution. At present, the flue gas of the power plant is routinely purified and discharged by the flue gas treatment system with the arrangement of "separation of smoke towers (indirect air cooling tower, desulfurization tower and chimney are arranged separately)". Specifically, the flue gas of the power plant first passes through the indirect air cooling tower, desulfurization tower The tower is purified, and...
