Technical Field
The utility model belongs to the technical field of landfill leachate defoaming, and particularly relates to a defoaming device applied to landfill leachate treatment.
Background
The landfill leachate is a high-concentration liquid produced by compacting and fermenting garbage in the process of stacking and landfill. Because the landfill leachate has complex water quality and contains various harmful inorganic matters and organic matters, and meanwhile, the liquid also contains a large amount of foam, the foam is not easy to eliminate due to the high concentration of the leachate, and the whole treatment process is slowed down. Meanwhile, when biochemical treatment is carried out on the landfill leachate, modes such as aeration and stirring are adopted, a large amount of foam is easier to overflow the tank body and even splashed everywhere, bad influence is caused to the surrounding environment and the health of operators, and the currently adopted landfill leachate foam eliminating device adopts a mode of spraying or adding a defoaming agent through a plurality of spray heads, but the spray method often causes the condition that the spray heads are blocked due to impurities in the leachate, so that the frequent replacement of the spray heads not only causes resource waste, but also is very troublesome in the actual operation process; in addition, foam in the percolate is eliminated by independently using the defoamer, the use amount of the defoamer is too large, and the cost is high.
Disclosure of Invention
The utility model aims to: the utility model aims to provide a defoaming device applied to landfill leachate treatment, which has good defoaming effect and low cost.
The technical scheme is as follows: the utility model relates to a defoaming device applied to landfill leachate treatment, which comprises a landfill leachate pool and a centrifugal pump communicated with the landfill leachate pool through a first pipeline, wherein the output end of the centrifugal pump is communicated with a high-pressure spray head through a pipeline; the output end of the centrifugal pump is connected with a second pipeline, the other end of the second pipeline is connected with a filter, the output end of the filter is communicated with a pipeline connector through a fifth pipeline, the pipeline connector is communicated with the dosing tank through a fourth pipeline, and the output end of the pipeline connector is communicated with the high-pressure spray head through a third pipeline.
Wherein, the output end of the third pipeline is at least connected with three groups of high-pressure spray heads.
And the fourth pipeline is provided with a first control valve.
Wherein, install the second control valve on the third pipeline.
Wherein, be equipped with the guide rail in the rubbish filtration pond, sliding connection has infrared sensor on the guide rail.
The beneficial effects are that: compared with the prior art, the utility model has the following advantages: according to the utility model, the foam height is detected by arranging the infrared sensor, and the foam in the landfill leachate is eliminated by adopting the self-suction rotary spray head, so that water resources are saved, and the foam at each blind angle position can be eliminated to the greatest extent; foam is removed in a physical mode, so that the consumption of defoamer is greatly reduced, and the material cost is reduced; a filter is arranged in front of the high-pressure spray head to prevent impurities in the percolate from blocking the high-pressure spray head.
