Title:
DUST-COLLECTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/172720
Kind Code:
A1
Abstract:
The present invention comprises: a dust-containing gas induction tube for inducing dust-containing gas, the end of the dust-containing gas induction tube being reduced conically such that the same has an outflow port; a venturi tube having a dust-containing gas passage connected to the outflow port of the dust-containing gas induction tube such that dust-containing gas passes through the same, the venturi tube having a water supply passage for supplying water to the dust-containing gas passage, and the venturi tube generating mixed gas, which is a mixture of the dust-containing gas and fog-like small water droplets, and releasing the same downstream; a cyclone having a cylindrically shaped portion and a conically shaped portion extending downward from the cylindrically shaped portion, the cyclone having an empty space portion formed therein by a cover that covers the cylindrically shaped portion, the cyclone comprising an introduction tube connected to the dust-containing gas passage of the venturi tube in a tangential type above the cylindrically shaped portion such that the mixed gas, which is a mixture of dust-containing gas and water, is introduced into the empty space portion; a dust-containing gas discharge tube having a suction port positioned inside the empty space portion of the cyclone through the cover, the dust-containing gas discharge tube penetrating the cover and extending out of the empty space portion; a primary precipitation tank attached to the lower end of the conically shaped portion of the cyclone and separated into multiple chambers; a refrigerant storage portion in which refrigerant is stored, the refrigerant storage portion surrounding a chamber, which is positioned on the lower portion among the chambers of the primary precipitation tank, in order to cool contaminated water stored in the chamber positioned on the lower portion; a water storage tank in which water supplied from the uppermost chamber of the primary precipitation tank is stored, the water storage tank comprising a water pressure level tank for supplying water to the water supply passage of the venturi tube; and an exhaust fan connected to the dust-containing gas discharge tube.
