Online dust discharging method based on dust remover

Abstract

The invention discloses an online dust discharging method based on a dust remover. The method comprises the following steps: regularly brushing dust on a filter cartridge or a filter screen, arranging a spray head at the lower part in the dust remover for spraying water, melting the brushed dust in water and discharging the dust from a water outlet pipe, and providing a water source for the spray head by a water tank; arranging a purification tank below the water outlet pipe and dividing into a dirty water area and a pure water area by a filter wall, arranging a filter barrel in the dirty water area, enabling dirty water discharged from the water outlet pipe to be filtered by the filter barrel and then enter the dirty water area, and enabling the dirty water in the dirty water area to be filtered by the filter wall and then enter the pure water area to become pure water; and when dust is brushed off, supplementing purified water in the purified water area into the water tank. Therefore, sewage with larger dust content discharged from the water outlet pipe of the dust remover is firstly filtered by the filter barrel, most impurities can be filtered out in the filter barrel, dirty water passing through the filter barrel enters the dirty water area and permeates the filter wall, and purified water penetrating through the filter wall can be supplemented into the water tank, so that the aim of saving water is fulfilled, the methodr is more environment-friendly, and pipeline accumulation can be prevented.

Description

technical field [0001] The invention relates to a dust remover, in particular to an online dust discharge method based on the dust remover. Background technique [0002] Dust collectors are commonly used in industry to purify the air. Existing dust collectors generally use filter cartridges or filter screens to filter out dust in the air based on the principle of filtration. It is inconvenient to disassemble the dust collector for collection. [0003] The bag filter disclosed in Chinese patent ZL2019224125280 uses the water spray method to discharge dust online. The principle is to make the filter cartridge rotatable, and the motor drives the filter cartridge to rotate regularly. Since a cleaning brush is installed on the side of the filter cartridge, the When the filter cartridge rotates, the dust on the filter cartridge will be brushed off.

[0003] The bag filter disclosed in Chinese patent ZL2019224125280 uses the water spray method to discharge dust online. The principle is to make the filter cartridge rotatable, and the motor drives the filter cartridge to rotate regularly. Since a cleaning brush is installed on the side of the filter cartridge, the When the filter cartridge rotates, the dust on the filter cartridge will be brushed off. In this patent, a nozzle is installed under the dust collector to spray water, and the dust that is brushed off will be melted into the water and then discharged from the outlet pipe, so that the accumulated dust in the filter cartridge during use The dust can be discharged online, but the patent adopts the direct discharge method to discharge the sewage, which is a defect. This method causes waste of water sources, and secondly, the discharged sewage is not treated, which is easy to affect the environment. It is easy to block the pipe, so it needs to improve its online dust removal method
