Waste residue collecting device for waste incineration and using method thereof

Abstract

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.

Description

technical field [0001] The invention relates to the field of garbage treatment, more specifically, to a waste residue collection device for garbage incineration and a method for using the same. Background technique [0002] Incineration residue refers to the general term for slag, leakage slag, boiler ash and fly ash produced in the process of waste incineration. The residue of MSW incineration treatment plant mainly includes two parts: the slag produced by the incinerator and the fly ash collected by the dust collector. The incineration ash contains a certain amount of heavy metal substances, which will pollute the environment if not handled properly. [0003] Since the fly ash contains more heavy metals, and the fly ash is easily scattered in the air, the pollution of the fly ash to the environment is more serious. At present, most of the waste residue treatment methods after waste incineration are simple slag and fly ash. Separation and insufficient treatment of heavy m...

The incineration ash contains a certain amount of heavy metal substances, which will pollute the environment if not handled properly

[0003] Since the fly ash contains more heavy metals, and the fly ash is easily scattered in the air, the pollution of the fly ash to the environment is more serious. At present, most of the waste residue treatment methods after waste incineration are simple slag and fly ash. Separation, the degree of treatment of heavy metals in fly ash is not enough, resulting in cumbersome and dangerous subsequent treatment procedures
