Different numbers of spray heads 21 can be configured according to the requirement of on-site dust removal. Also 22 in 2 is the water mist formed.
The key of this embodiment is to satisfy the following two conditions: (1) a collision area is arranged between the motion trail of the ejected dust-containing gas and the motion trail of the water mist, namely, the dust-containing gas and the water mist are respectively ejected and move according to certain inertia and need to collide, so that the dust-containing gas and the water mist can be ensured to be contacted with each other, and the possibility that the dust-containing gas is captured by the water mist can be further ensured; (2) the air current velocity of motion of the dusty gas that is erupted and the water smoke velocity of motion of water smoke have predetermined difference between them, through certain predetermined difference between air current velocity of motion and the water smoke velocity of motion like this, make the air current velocity of motion big certain difference relatively to the water smoke velocity of motion, or the water smoke velocity of motion big certain difference relatively to the air current velocity of motion, just so can guarantee the motion orbit of at least one in dusty gas or the water smoke, be difficult to receive the influence of the air current that dusty gas and water smoke motion caused, thereby can guarantee certain inertia linear motion as far as possible. Therefore, through the cooperation of the two conditions, more dust-containing gas and water mist can be contacted in the collision area and can be fully collided as far as possible, and the capacity of the water mist for capturing the dust-containing gas is improved, so that the dust falling and dust removing effect of the water mist on the dust-containing gas is enhanced.
