The pulse jet dust collector operates normally by having the dusty gas enter the hopper through the inlet. Due to the rapid expansion of the gas volume, some coarser dust particles fall into the hopper due to inertia or natural sedimentation. The rest of the dust particles, mostly, rise with the gas flow into the bag chamber and are trapped on the outside of the filter bags after passing through the filter bags. The purified gas then enters the upper housing through the filter bags and is discharged into the atmosphere through the valve plate holes and exhaust outlets, achieving the dust removal purpose. As the filtration progresses, the resistance of the dust collector also increases. When the resistance reaches a certain level, the cleaning controller issues a cleaning command. First, it closes the lifting valve plate to cut off the filtration gas flow; then, the cleaning controller sends a signal to the pulse solenoid valve. As the pulse valve sends a high-pressure reverse airflow used for cleaning into the bags, the filter bags quickly inflate and produce strong vibrations, causing the dust on the outside of the filter bags to fall off, achieving the cleaning purpose. Since the equipment is divided into several compartments, the above process is carried out sequentially. While one compartment is being cleaned, the other compartments continue to operate normally, ensuring the continuous and normal operation of the equipment. The ability to handle high concentrations of dust is primarily due to the short cleaning time required for this strong cleaning (a single blow only takes 0.1 to 0.2 seconds).
Technical Features
(1) No pre-dust removal equipment required; capable of handling dust concentrations up to 1000mg/m3 in one go, with emissions less than 50mg/m3; simple process flow; (2) No need for blowing pipes inside the bag house; bag change is convenient outside the machine.
(3) Embedded elastic mouth, excellent sealing performance.
(4) Pulse valve quantity is low, dust removal intensity is high, and operation is quick.
(5) The entire unit is equipped with microcomputer automatic control, allowing for easy adjustment of parameters and achieving jobless operation; (6) Filter bag lifespan exceeds two years.
(7) Easy to achieve isolation and maintenance.
