Vacuum garbage collection system refers to the process that domestic garbage is pumped to the central garbage collection station by negative pressure technology through pre-laid pipeline system, and then transported to the garbage disposal site by compression truck. This negative pressure pneumatic collection system is a self-contained collection system, which is composed of a dump channel, a channel valve pipeline, a mechanical center, a collection and transfer station and so on.
The working principle of the vacuum pipeline garbage collection system is equipped with an induction fan at the end of the collection system. When the fan runs, the negative pressure is formed inside and outside the system, which causes the pressure difference between the pipeline and the air to be sucked into the pipeline. At the same time, garbage is carried into the pipeline by the air and is transported to the separator where garbage and air are separated. The separated garbage is discharged by the unloader, and the air is sent to the separator. The dust is cleaned and discharged.
The vacuum pipeline garbage collection system mainly includes garbage disposal outlet, floor vertical pipeline, horizontal pipeline, horizontal pipeline and central collection station.
In the building, a garbage disposal outlet will be set up on each floor, close to the garbage disposal outlet, and a vertical garbage pipeline will be set up. At the bottom, a garbage discharge valve will be connected with a horizontal pipeline embedded in the ground, leading to a sealed central collection station. All kinds of garbage produced every day are put into the garbage disposal outlet and into the vertical garbage pipeline. When the amount of garbage reaches a certain level, the central console sends out instructions to start work. The exhaust device in the garbage station starts automatically and produces negative pressure airflow in the horizontal pipeline. The system automatically opens the garbage discharge valve at the bottom of the vertical garbage pipeline, and the garbage stored on the top of the valve is sucked into the underground pipeline network and transported to the central collection station for the separation of garbage gas and solid. The gas part is discharged after efficient treatment, while the solid waste is compressed and transported to the garbage tank, and then transported to the garbage treatment plant for incineration, power generation or landfill treatment.
