<p>A system wherein a first dust-containing gas current is jetted out through a jetting port. A gas current is jetted out from a direction opposed to the first gas current, and both gas currents are made to collide with each other. The flow velocity of the dust-containing gas current is made to quickly and infinitely approach zero and only the contained dust is made to advance by its inertia force. A washing liquid is sent into the gas collision system, and the dust in the gas current is made to collide with the washing liquid at a high velocity by its inertia force. The dust in the gas is caught with the washing liquid. To make the dust-contain-ing gas current collide with the gas current opposed to it, the dust-containing gas is pressed into a dust collector with means, such as a pump,and is jetted out through jetting ports opposed to each other in the dust collector. As a means of sending the washing liquid into the system wherein the gas current collides, and wherein gas flow velocity is made to quickly and infinitely approach zero and only the contained dust is made to advance by the inertia force, the washing liquid is pre-contained in the gas or sprinkled in the system, or the jetting ports opposed to each other are dipped in the washing liquid. The liquid pressure and jetting pressure are balanced with each other so that a film of the washing liquid may be formed in the gas current collision system.</p> |
