The invention discloses a waste residue collecting device for waste
incineration and a using method thereof, and belongs to the field of waste
incineration. The waste residue collecting device for waste
incineration comprises a box body, wherein a crushing cavity is formed in the upper portion of the box body, two symmetric crushing machines are symmetrically installed on the inner wall of the crushing cavity, blades on the two crushing machines are staggered, the upper portion of the crushing cavity communicates with a feeding
pipe, and a separation cavity is formed in the middle of the box body and communicates with the crushing cavity. By means of the waste residue collecting device, furnace
slag and
fly ash in incineration waste residues can be quickly separated, and subsequent
processing is facilitated; moreover, heavy
metal contained in the
fly ash can be adsorbed to lower the
pollution degree of the
fly ash, the principle of negative pressure is utilized for making the fly ash float towards a negative pressure cavity,
snowflake-shaped adsorption sheets are utilized for adsorbing the fly ash, and adsorbing heavy
metal in the fly ash, so that preliminary
filtration of the flyash is achieved, and then the fly ash is filtered through a dust
settling pocket to ensure that gas discharged in air is unlikely to bring about
air pollution.
