Description
Technical Field
The invention relates to the field of dust collection equipment, in particular to a filter bag ash removal device and a bag type dust collector.
Background
The bag dust collector is a dry dust filter, which is suitable for collecting fine, dry and non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, dust-containing gas is filtered by utilizing the filtering effect of fiber fabric, and when the dust-containing gas enters the bag type dust collector, dust with large particles and large specific gravity falls down due to the effect of gravity and falls into the ash bucket, and when the gas containing finer dust passes through the filter bag, the dust is blocked and adhered to the filter cloth, so that the gas is purified. Over time, the resistance of the filter cloth increases, resulting in a reduced filtering effect. At this time, a back blowing ash removal or pulse blowing ash removal mode is generally adopted, and back blowing/pulse airflow is introduced into the filter bag through the filter bag mouth, so that the filter cloth expands and contracts under the back blowing/pulse airflow, and dust on the filter cloth falls off to complete dust removal.
However, the blowback/pulse air flow introduced from the upper side is limited by the length of the filter bag, so that the energy of the blowback/pulse air flow is gradually consumed, and the impact force of the blowback/pulse air flow received by the filter cloth is smaller the farther the filter cloth is away from the filter bag mouth, which causes the non-ideal ash removing effect of the filter bag and seriously affects the subsequent filtering of dust-containing gas.
