Many dust removal systems face incomplete ash cleaning problems after long term operation, residual dust accumulates on dust bag surface leading to high pressure drop and insufficient air volume. Reasonable venturi structural design strengthens pulse jet airflow impact force, realizing thorough dust cake shedding and restoring original ventilation performance of dust bag.
Venturi installs at the top opening of dust bag, high pressure pulse airflow passes through narrow throat structure to generate instantaneous airflow acceleration and negative pressure suction effect. The boosted airflow penetrates deep into dust bag interior to impact full bag surface, solving the problem of weak cleaning force at the bottom of long dust bag without venturi matching.
Without venturi auxiliary, pulse airflow only impacts upper section of dust bag, bottom dust cake cannot be shaken off completely and accumulates gradually. Venturi guides uniform airflow distribution from top to bottom inside dust bag, each area of filter bag receives balanced impact force, eliminating local dust blockage caused by incomplete cleaning.
Different length and caliber dust bag need matched venturi inner diameter and throat size. Short small diameter dust bag fits mini venturi with narrow throat, extra long large industrial dust bag selects large flow venturi to guarantee sufficient airflow output. Custom venturi size can be provided under OEM service to match non standard customized dust bag dimensions.
Complete ash cleaning reduces dust residue accumulation on dust bag surface, slowing filter material blockage speed and extending dust bag service cycle by twenty to thirty percent. Stable low pressure drop lowers dust collector fan power consumption daily, cutting electricity expenditure of dust removal workshop. Venturi metal accessories have long service life without frequent replacement after one time installation.
