Description
Technical Field
[0001] The utility model belongs to the technical field of boiler dust collectors, and particularly relates to a pulse dust cleaning device for a boiler dust collector. Background Technique
[0002] A boiler dust collector is a device used to treat the soot generated during the combustion process of a boiler. It can effectively remove particulate matter in the soot, reduce environmental pollution, and ensure air quality. However, after long-term use of traditional boiler dust collectors, a large amount of dust accumulates on the filter bags in the dust collector, which in turn affects the dust removal effect.
[0003] When the existing boiler dust collector is cleaning ash, it generally uses a pulse valve to repeatedly blow the filter bags multiple times, so that the dust on the filter bags shakes off to achieve ash cleaning. As the filtration time extends, the dust layer on the filter bags in the dust collector body continuously thickens, and the resistance of the dust collector body continuously rises. When the equipment resistance rises to the set value, the ash cleaning mechanism starts to perform pulse ash cleaning. First, a compartment lift valve closes to cut off the filtered air flow. Then, the electromagnetic pulse valve opens, and the compressed air rapidly expands in the upper box body in an extremely short time and rushes into the filter bags, causing the filter bags to expand and deform to generate vibration. Under the action of the reverse air flow scouring, the dust attached to the outer surface of the filter bags is peeled off and falls into the ash hopper. After the ash cleaning is completed, the electromagnetic pulse valve closes, and the lift valve opens, and this compartment resumes the filtration state. The ash cleaning of each compartment is carried out in sequence. From the start of ash cleaning in the first compartment to the start of the next ash cleaning is an ash cleaning cycle. The dust intercepted through the filtration and ash cleaning work falls into the ash hopper.
[0004] After the existing pulse ash cleaning device finishes ash cleaning, a large amount of dust accumulates in the ash hopper and needs to be collected and processed by operators. However, during the process of discharging the dust from the ash hopper, it is easy to cause the dust to fly, so that the flying dust is inhaled by the operators, which in turn affects the physical health of the operators.
