Problems solved by technology

[0002] Existing desulfurization towers are usually used in conjunction with electrostatic precipitators to achieve the environmental protection goals of flue gas desulfurization and dust removal. They have the disadvantages of large floor area, high environmental protection investment costs, cumbersome operations, and low dust removal efficiency, and cannot achieve flue gas desulfurization. off white
With the improvement of the level of economic development and the increasing emphasis on environmental protection today, the existing desulfurization towers can no longer meet the requirements of the latest emission indicators of soot pollutants in my country's environmental protection

Abstract

The invention relates to a flue gas condensation de-whitening defogging and dedusting tower. The flue gas condensation de-whitening defogging and dedusting tower includes a tower body. A slurry area,a spraying area, a defogging and dedusting area and a heating area are sequentially arranged in the tower body from bottom to top. A plurality of spraying devices arranged at intervals from bottom totop are arranged in the spraying area. A tube-bundle type defogging and dedusting device is arranged in the defogging and dedusting area. A heating device is arranged in the heating area. The sprayingdevices are used for condensing flue gas, the tube-bundle type defogging and dedusting device is used for defogging and dedusting the condensed flue gas, and the heating device is used for heating the flue gas after defogging and dedusting. The flue gas condensation de-whitening defogging and dedusting tower has the advantages of simple operation, floor space saving, low operation cost and high dedusting efficiency.

Description

technical field [0001] The invention belongs to the field of flue gas pollutants and flue gas dewhitening control, and in particular relates to a flue gas condensation dewhitening, mist and dust removal tower. Background technique [0002] Existing desulfurization towers are usually used in conjunction with electrostatic precipitators to achieve the environmental protection goals of flue gas desulfurization and dust removal. They have the disadvantages of large floor area, high investment costs for environmental protection, cumbersome operations, and low dust removal efficiency, and cannot achieve flue gas desulfurization. off white. With the improvement of the level of economic development and the increasing emphasis on environmental protection today, the existing desulfurization towers can no longer meet the requirements of the latest emission indicators of soot pollutants in my country's environmental protection. Therefore, it is particularly important to seek a flue gas...
