Technical scheme: a kind of dust collector of water curtain, fluid delivery tube top in dust collector of water curtain is positioned at water curtain dust excluding hood and fluid delivery tube outlet is straight to water curtain dust excluding hood cover cap, one circle or multi-turn water spray water pipe circle are distributed in water curtain dust excluding hood inwall and connect with water inlet pipe, sump pit tilts greatly admittedly on fluid delivery tube and is positioned at below water curtain dust excluding hood, and the outage in sump pit connects with discharging tube。

This utility model is compared with background technology, and screen collector combines with pulse bag type dust collector, and one is fundamentally solve pulse bag type dust collector easily to be blocked by miniature dust adhesion and the current of electric that causes is uprushed, energy consumption increases technical barrier；Two is avoid motor in bag pulse dedusting device to uprush protection automatically due to electric current and the dedusting work that causes stops, and drastically increases the efficiency of dust collection of bag pulse dedusting device；Three be not only fundamentally solve miniature granularity of dust too little and by cloth bag pulsed dust-removing device discharge technical barrier, and obtain strong concrete be badly in need of micronic dust dust filler。
