Problems solved by technology

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

Embodiment 1

[0043] see Figure 1-5 , a waste residue collection device for waste incineration, including a box 1, please refer to figure 1 and Figure 4, the upper part of the box body 1 is provided with a crushing cavity, and two symmetrical crushers 2 are installed on the inner wall of the crushing cavity, and the blades on the two crushers 2 are dislocated. The middle of the body 1 is provided with a separation cavity 4, the bottom inner wall of the separation cavity 4 is inclined, and the bottom of the separation cavity 4 is inclined to both sides respectively. The inclined bottom allows the solid slag to fall into the blanking cavity 15 smoothly. In order to prevent the fly ash from falling into the blanking cavity 15 when it is blown up, and the separation cavity 4 is communicated with the crushing cavity, the bottom inner wall of the separation cavity 4 is fixedly connected with a bracket 5, and the upper end of the bracket 5 is rotatably connected with a material holding table 6....

Abstract

The invention discloses a waste slag collection device for garbage incineration and a method for using the same, and belongs to the technical field. A waste slag collection device for garbage incineration includes a box body, and a crushing cavity is provided on the upper part of the box body. Two crushing chambers are installed on the inner wall of the crushing cavity. A symmetrically arranged crusher, and the blades on the two crushers are misplaced. The upper part of the crushing chamber is connected with a feeding pipe, and the middle part of the box is provided with a separation chamber, and the separation chamber is connected with the crushing chamber. The rapid separation of slag and fly ash is convenient for subsequent processing, and it can also adsorb heavy metals contained in fly ash to reduce the pollution degree of fly ash. The negative pressure principle is used to let the fly ash float to the negative pressure chamber, and the snowflake-shaped The adsorption sheet is used to adsorb the fly ash. The adsorption sheet absorbs the heavy metals in the fly ash to realize the preliminary filtration of the fly ash, and then filters the fly ash through the dust bag to ensure that the gas discharged into the air will not pollute the air. .

Description

technical field [0001] The invention relates to the field of garbage disposal, and more particularly, to a waste residue collecting device for garbage incineration and a method for using the same. Background technique [0002] Incineration residue refers to the general term for slag, slag leakage, boiler ash and fly ash produced in the process of waste incineration. The residue of the municipal solid waste incineration 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 properly treated. [0003] Since fly ash contains a lot of heavy metals, and fly ash is easily dispersed in the air, the pollution of fly ash to the environment is more serious. Separation, the degree of treatment of heavy metals in fly ash is insufficient, resulting in cumbersome and dangerous subsequent treatment procedures. ...
