Wet dust collector with high-frequency vibration filter screen

Abstract

The invention discloses a wet dust collector with a high-frequency vibration filter screen and belongs to the field of air filtration. The wet dust collector with the high-frequency vibration filter screen mainly comprises a dust collector housing, a spray component, an excitation device, a filter component, a dewatering component, an axial flow fan and the like. The spray component, the filter component, the dewatering component and the axial flow fan are sequentially mounted in the dust collector housing in the direction from the inlet to the outlet. A filtering filter element of the filtercomponent is obtained by laminating fiber bundles with nano-fiber whiskers after being subjected to hydrophobic treatment. In the process of filtration, a high-frequency vibration source excites the filter component, so that the fiber whiskers vibrate at high frequency in an equilibrium position to enhance the contact probability among the whiskers, dust and water mist, so as to improve the capture efficiency of fine dust. Furthermore, the vibration of the fiber bundles and the fiber whiskers effectively prevents the stagnation of dust-containing water droplets inside the filter component to accelerate the flow of the dust-containing water droplets so as to solve the blocking problem of the filter component. The dust collector has the advantages of high dust removal efficiency, difficultyin blocking of wire meshes and low pressure loss.

Description

technical field [0001] The invention relates to a wet dust collector with high-frequency vibration of the filter screen, which belongs to the field of air filtration. Background technique [0002] Wet dust collector is a kind of separation equipment that uses water to collect dust particles. It has the advantages of simple equipment, low operating cost, and small maintenance. It is widely used in various fields of the national economy, such as mining, steel smelting, and boiler combustion. The filter dust collector in the wet dust collector has the advantages of small pressure loss, large specific surface area, and compact structure, and is especially suitable for dust control in narrow spaces. [0003] Wet filter dust collector has been widely concerned and researched due to its excellent performance, such as: Sun Xi invented the "tube curtain-wet fiber grid composite dust collector" (patent: CN102359390A), using fiber grid as a filter component, and water Dust is collecte...

AI Technical Summary

Problems solved by technology

At the same time, the super-hydrophobic fiber tentacles and fiber bundles vibrating at high frequency prevent dust-laden water droplets from staying inside the filter assembly, and flow into the sewage tank under the action of gravity, which solves the problem of easy blockage of the wire mesh dust collector
