Activated carbon micro hole ultra-fine dust wind power screening device

Abstract

The invention discloses an activated carbon micro hole ultra-fine dust wind power screening device. A shell, a feeding port in the top end of the shell and a discharging port in the bottom end of theshell are included. A grid plate is arranged in the feeding port. The part, extending into the shell, of the feeding port is provided with a discharging pipe. Flow guiding plates are arranged on the two sides of the discharging pipe. A material dividing cone hopper is arranged in the shell and located under the flow guiding plates, annular airflow distribution holes are formed in the two sides ofthe material dividing cone hopper, and the discharging port is located under the material dividing cone hopper. Static pressure chambers are arranged on the two sides of the shell, air inlet cavitiesare formed in the top ends of the static pressure chambers, and a draught fan is arranged on one side of the shell. The activated carbon micro hole ultra-fine dust wind power screening device is ingenious in structure, mechanical motion parts and damageable parts do not exist, and maintenance is avoided.

Description

technical field [0001] The invention relates to the technical field of dust screening, in particular to an activated carbon microporous ultrafine dust wind screening device. Background technique [0002] Activated carbon flue gas purification technology uses activated carbon to remove harmful substances in the gas. During the transportation and reaction of activated carbon, coke and fine dust will be generated due to collision and friction. The dust in the fine powder flue gas cannot be removed by conventional vibrating screens in the micropores. During the circulation of activated carbon, the ultrafine dust in the micropores will return to the flue gas purification system, resulting in The dust concentration is relatively high. If it is necessary to reduce the dust concentration in the flue gas to achieve ultra-low emissions, it is often necessary to add dust collector facilities that match the flue gas volume, which requires high investment and high energy consumption.

AI Technical Summary

Problems solved by technology

[0003] The activated carbon adsorption bed adsorbent that does not meet the particle size requirements will reduce the porosity, which will lead to a decrease in dust removal and desulfurization efficiency, an increase in bed resistance, and even hot spots that may cause safety accidents. Friction will produce broken coke and fine dust for separation

[0004] At present, vibration screening technology is widely used, which has a good effect on the mixed materials with large particle mass and different particle sizes, but it has no effect on the fine dust and light impurities attached to the micropores of activated carbon.
