Description

Technical Field

[0001] The utility model relates to the technical field of flue gas treatment, in particular to a tube bundle type dust and mist remover. Background Art

[0002] The demister is a key equipment in the wet flue gas desulfurization system, and its performance directly affects whether the wet scrubbing flue gas desulfurization system can operate continuously and reliably. The tube bundle dedusting demister is usually connected by multiple tube bundle dedusting and demister cylinders. The demister cylinder includes a multi-stage cyclone and a converging and guiding device. When the desulfurized flue gas passes through the cyclone, centrifugal motion is generated. The fine droplets and dust particles in the high-speed airflow are separated from the gas under the action of centrifugal force and flow down along the inner wall of the demister cylinder to achieve gas dust removal and demistering.

[0003] According to a tube bundle type dust collector and demister disclosed on the patent website (authorization announcement is CN 212941886U), "a tube bundle type dust collector and demister comprises an upper fixed plate, a tube bundle demister and a lower fixed plate connected in sequence; the tube bundle demister is fixed to the support beam through the lower fixed plate, the support beam horizontally spans the inner wall of the desulfurization tower, and the multiple tube bundle demisters are connected in parallel through the upper fixed plate and the lower fixed plate; the annular ring formed by the connection between the tube bundle demister and the upper fixed plate and the lower fixed plate is respectively provided with a circular upper vent hole and a circular lower vent hole."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, the device adopts a multi-stage cyclone design and adjusts the inclination angle between the cyclone blade plane and the central axis, thereby changing the airflow velocity of the desulfurized flue gas passing through the desulfurized flue gas in the desulfurization body. However, in actual use, when faced with gases of different concentrations, the device cannot change the diameter of the inlet port, thereby being unable to reasonably adjust the gas feed rate to change the dust removal effect. In addition, the overall tube bundle length of the device is fixed and cannot be changed according to actual requirements, thereby being unable to extend the residence time of the gas in the tube bundle. Therefore, it is necessary to improve a tube bundle type dust and mist remover. Utility Model Content
