Description

Garbage leachate collecting and filtering device

Technical Field

The utility model belongs to the technical field of refuse treatment, concretely relates to filtration liquid collects filter equipment.

Background

The household garbage incineration power generation becomes the mainstream mode of garbage disposal in China due to the advantages of harmlessness, reduction, resource utilization and the like. After the garbage is transported to a garbage bin, the garbage is subjected to short storage fermentation for 5 to 7 days, and leachate accounting for about 30 percent of the total weight of the garbage entering the plant is generated in the fermentation process. A large amount of percolate is generally attached to the combustible waste which is put into the incinerator for incineration.

One of the most main devices of the current waste incineration power generation is the grate type incinerator, each grate type incinerator is provided with a feed hopper, a material pusher is arranged below the feed hopper, and the bottom of a chute is provided with a material pusher which is responsible for conveying the waste of the feed hopper to a grate for combustion.

After the garbage is thrown into the feeding hopper of the incinerator, the garbage can be retained in a chute below the feeding hopper for a period of time to wait for pushing the material. During this time, the percolate will flow downwards under the influence of gravity, since the refuse contains a large amount of percolate. In order to avoid leachate to flow into the hearth, reduce the temperature of the incineration environment and influence the working condition of garbage combustion, the incinerator is provided with a leachate collecting hopper under the bottom plate of the material pusher during design so as to collect leachate in garbage and send the leachate to a treatment station for centralized treatment through a pipeline.

The conventional percolate collecting hopper is of a conical structure, and a vertical pipeline is arranged below the percolate collecting hopper. Due to the extrusion effect of the pusher and the lack of filtering measures, the percolate collected in the collecting hopper is carried with more dregs, which easily causes the blockage of a conveying pipeline.

Generally, after a pipeline below the collecting hopper is blocked, the manhole needs to be manually opened for cleaning, a special tool is needed for opening and closing the manhole, time and labor are wasted, cleaning water is sprayed in the cleaning process for washing, and the amount of percolate is increased, so that the percolate treatment cost is increased; some mills adopt to set up the flushing pipe, regularly wash, have increased the infiltration liquid measure, cause the treatment cost to increase, to some great or longer dregs, also can't wash totally, still cause the jam, still need manual overhaul clearance. Some factories adopt common filter screens, and the filter screen mounting, dismounting and cleaning processes are complex, long in time consumption and inconvenient.

The application number is CN 201921438821.8's a stoker filtration liquid collection filter equipment, including the hollow box, wherein, the upper end of hollow box sets up the filtration liquid import, the lower extreme sets up the filtration liquid export, the filtration liquid import is the circular pipeline, and the circular pipeline extends to in the hollow box, the outer pipe wall of the circular pipeline and hollow box welding, the filtration liquid export is funnel type; the drawer type filter is arranged in the middle of the hollow box body, a handle is arranged on the outer side of a front panel of the drawer type filter, the outer periphery of the front panel, which is in contact with the hollow box body, is sealed through a circle of rubber pad, a filter screen is arranged on the bottom surface of the drawer type filter, and rollers are arranged at the bottoms of the two side panels respectively and slide on rails at corresponding positions on the inner side of the hollow box body. The filter device adopts a drawer type design, can be quickly drawn out when the filter screen is cleaned, is convenient and quick, and reduces the using amount of flushing water while reducing the blockage of garbage dregs on a collecting hopper pipeline; but also has the following disadvantages:

adopt the drawer type filter to filter, though convenient dismouting, in case the filtration pore jam of drawer type filter will influence filtration efficiency, need frequently take out the drawer type filter and clear up, it is very troublesome, only have the one deck moreover and filter, the filter effect is not good.
