Embodiment Construction
[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0024] refer to figure 2 , the embodiment of the bottom slag water washing and sorting system of the present invention is suitable for washing and sorting the bottom slag produced by the incinerator (not shown) with working water 100. The sewage flowing out of the bottom slag washing and sorting system flows into the sewage treatment system 102 for subsequent treatment. In this embodiment, the bottom slag washing and sorting system includes a bottom slag wet screening unit 2 , a filter unit 3 , and a water storage device 4 .
[0025] The bottom residue wet screening unit 2 is used for performing wet screening treatment on the bottom residue with the working water 100 , and thus produces sewage. In this embodiment, when using the bottom slag wet screening unit 2 to carry out wet screening of the bottom slag, a water supply unit is installed in a dru...

Abstract
A bottom slag washing and sorting system is suitable for performing washing and sorting processing on bottom slags which are generated by an incinerator by means of working water. Sewage which is flowed out of the bottom slag washing and sorting system enter a sewage processing system for subsequent processing. The bottom slag washing and sorting system comprises a bottom slag wet screening unit,water storage equipment and a filtering unit. The bottom slag wet screening unit performs wet type screeing processing on the bottom slag through the working water for generating the sewage. The waterstorage equipment comprises a first pond and a second pond. The sewage which is generated by the bottom slag wet screening unit flows into the first pond for reducing an acid value or a base value and eliminating bubbles. The filtering unit filters the bottom slag by means of the sewage processing in the first pond, thereby obtaining fine aggregate. One part of the generated sewage is dischargedto the sewage processing system for subsequent processing. The other part of the sewage generated by the filtering unit is used as recycled water and flows into the second pond for reducing the acid value or the base value and eliminating the bubbles so that the recycled water which flows out of the second pond can flow back to the bottom slag wet screening unit for recycling.
Description
technical field [0001] The invention relates to a treatment system for bottom slag produced by an incinerator, in particular to a water washing and sorting system for bottom slag. Background technique [0002] Garbage disposal is a major environmental issue faced by human beings after high industrialization and urbanization. Among the many garbage disposal methods, first using an incinerator to burn and incinerate the garbage and then dispose of it is a widely used garbage disposal method at present. Using an incinerator to burn garbage has at least the following advantages: (1) After the garbage is burned and incinerated, the volume of the garbage can be greatly reduced; (2) The substances harmful to the environment contained in the garbage can be burned by incineration. (3) The combustion of the incinerator is carried out in a controlled environment, and the exhaust gas is properly monitored and treated, which can reduce the harm to the human body; and (4) The bottom ash ...
