2results about How to "Improve dust collection effect" patented technology

The utility model discloses a kind of powder dust collection devices, including central cloth bag dust removal cylinder, cyclone dust removal shell and outer back loop pipe, the top of the cyclone dust removal shell is equipped with central hole, the central cloth bag dust removal cylinder is inserted into the central hole, the outer back loop pipe is sleeved to the outside of the central cloth bag dust removal cylinder, the ring inside of the outer back loop pipe is connected to the cylinder wall of the central cloth bag dust removal cylinder by at least two ring inner branch pipes, the outside of the cyclone dust removal shell is installed with controller, the top of the central cloth bag dust removal cylinder is installed with cover, cloth bag hole disc is installed in the cylinder of the central cloth bag dust removal cylinder.It is beneficial to effect that: by multistage dust removal, dust removal effect and dust collection effect are better, increase separation effect, greatly reduce the occupation of site space, realize pulse to remove dust and carry out backflow treatment under non-stop state, reduce dust accumulation of cloth bag in use process, improve the dust removal and collection efficiency of device whole.

This application discloses a rectifying electrostatic precipitator, belonging to the field of dust collector technology. By sequentially setting a guide layer, a mixing layer, and a stabilizing layer in the inlet conical section of the outer shell, multiple airfoil-shaped guide elements in the guide layer evenly distribute the airflow, directing it across the entire inlet conical section of the outer shell. Multiple sets of grid holes in the mixing layer employ a staggered grid design to break up large-scale eddies in the flue gas guided by the guide layer, reducing them to smaller sizes and achieving initial velocity equilibrium. The stabilizing layer features a honeycomb open-cell design; the honeycomb structure effectively manages the airflow and stabilizes the velocity. Thus, the flue gas undergoes a three-stage process of "guidance-breakup-management" to achieve refined flow field treatment, improve velocity distribution uniformity, and reduce inlet local resistance.
