Description

Filter equipment is collected to stoker filtration liquid

Technical Field

The utility model belongs to the technical field of energy-saving equipment, in particular to filter equipment is collected to stoker filtration liquid.

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.

Disclosure of Invention

To the problem that exists, the utility model aims at providing a filter equipment is collected to stoker filtration liquid can prevent effectively that rubbish dregs from blockking up the pipeline, reduces filter equipment washing water yield simultaneously.

The utility model aims at realizing through the following technical scheme:

a percolate collecting and filtering device of a material pushing device comprises a hollow box body, wherein a percolate inlet is formed in the upper end of the hollow box body, a percolate outlet is formed in the lower end of the hollow box body, the percolate inlet is a circular pipeline, the circular pipeline extends into the hollow box body, the outer wall of the circular pipeline is welded with the hollow box body, and the percolate outlet is in a 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.

Furthermore, the leachate outlet is a funnel-type outlet with an inclination angle not lower than 60 degrees.

Furthermore, the four surfaces of the hollow box body and the drawer type filter are made of S30408 stainless steel plates, and the bottom surface of the drawer type filter is a stainless steel metal filter screen.

The utility model discloses compare prior art's beneficial effect does:

1. filter equipment is collected to stoker filtration liquid, adopt the drawer type design, can take out convenient and fast rapidly when clearing up the filter screen. The filter screen at the bottom of the drawer type filter is convenient to wash, and the water consumption is small. This filter equipment has reduced the quantity of sparge water when reducing dregs jam and collecting fill pipeline possibility. Because the washing water is polluted after being used and treated as the leachate, the reduction of the consumption of the washing water can directly reduce the sewage treatment load impact on a leachate treatment system during washing, thereby not only maintaining the stability of the system, but also reducing the operation cost;

2. in the filter device for collecting percolate of the material pushing device, the percolate inlet is a circular pipeline, the circular pipeline extends into the hollow box body, the diameter of the circular pipeline is smaller than the width of the drawer type filter, so that dregs are prevented from flowing into a gap between the drawer type filter and the box body along the four walls of the box body, and the percolate and the dregs entering from the inlet pipe can completely pass through the filter screen on the bottom surface, thereby avoiding the blockage of the drawer type filter and the incapability of action; meanwhile, the measures can also avoid the problem that the slag of the percolate is adhered to the interface of the inlet pipe and the box body due to incomplete welding or other reasons, and the problem that wall hanging is formed and the percolate is blocked up day by day.
