Problems solved by technology
[0002] Due to the high temperature and high concentration of SO 2 Due to the particularity of the dust, it is difficult to meet the discharge requirements with a normal bag filter, and the conventional water dedusting and spray desulfurization cannot meet the discharge requirements. Therefore, the high-temperature and high-concentration flue gas desulfurization and dust removal technology must be combined with the characteristics of flue gas , adopt different methods to ensure stable discharge of environmental protection requirements

Embodiment Construction
[0023] The present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0024] Such as figure 1 As shown, a high-temperature, high-concentration flue gas desulfurization and dust removal system includes a flue gas inlet 2, a droplet formation and high-density fog chamber 1, a water bath vortex purification wall 4, a droplet precipitation chamber 3, and a cyclone centrifugal purification Device 5 and lye pool 6. Wherein, the lye pool 6 is located at the bottom of the flue gas desulfurization and dust removal system, above which is a high-density fog chamber 1 and a droplet precipitation chamber 3, and a water bath vortex type is set between the high-density fog chamber 1 and the droplet precipitation chamber 3 The purification wall 4, the u...

The invention provides a high-temperature and high-concentration flue gas desulfurization and dust removal system. The high-temperature and high-concentration flue gas desulfurization and dust removal system comprises a flue gas inlet (2), a fog droplet formation and high-dense fog chamber (1), a water bath swirl type purification wall (4), a fog droplet sedimentation chamber (3), a cyclone centrifugal purification device (5) and an alkaline liquid pond (6). The high-temperature and high-concentration flue gas desulfurization and dust removal system can be used for effectively treating high-temperature and high-concentration flue gas and carrying out desulfurization and dust removal to realize standard emission, and operates steadily and normally.
Description
technical field [0001] The invention relates to the technical field of flue gas treatment, in particular to a high-temperature, high-concentration flue gas desulfurization and dust removal system and its application. Background technique [0002] Due to the high temperature and high concentration of SO 2 Due to the particularity of the dust, it is difficult to meet the discharge requirements with a normal bag filter, and the conventional water dedusting and spray desulfurization cannot meet the discharge requirements. Therefore, the high-temperature and high-concentration flue gas desulfurization and dust removal technology must be combined with the characteristics of flue gas , to adopt different methods to ensure stable discharge of environmental protection requirements. [0003] Normal flue gas contains SO 2 Concentration 800-1200mg / Nm 3 , dust concentration 500-800mg / Nm 3 . When encountering SO 2 Concentration 3000-5000mg / Nm 3 , dust concentration 2000-5000mg / Nm ...
