A kind of garbage separating method and device that is applicable to garbage collecting and transporting vacuum pipeline system
Technical field the present invention relates to a kind of garbage separating method and device that is applicable to garbage collecting and transporting vacuum pipeline system, more particularly, relate to a kind of make air with certain speed and rubbish mix that logistics is carried out fast at the end of delivery duct, effectively separation processes method and corollary apparatus thereof.
The technical background garbage collecting and transporting vacuum pipeline system is a kind of refuse collection and delivery system of later-model, efficient, environmental protection, is a kind of new ideas system that overturns traditional refuse collection mode and means.Its groundwork is to produce high velocity air in the pipeline by closed conduit being vacuumized make, and utilizes gas delivery rubbish, is a kind of pipeline air-transport system.In bigger scope, be a kind of urban duct logistics system.
The design concept of garbage collecting and transporting vacuum pipeline system is: with pipeline the rubbish vertical tube that is built in the capture range in the building is connected to one from resident's central refuse collection station far away, all rubbish that are positioned at capture range all will enter system by the rubbish dispensing port of each floor, through arriving central refuse collection station behind a series of buried pipeline, separate and compression set through rubbish again, be pushed into the leak free garbage container at last and be transported to landfill yard or final disposal is carried out in the waste incineration field.The operation of whole garbage collecting and transporting vacuum pipeline system be fully enclosed, automation with mechanization, in the collection process, rubbish is handled without staff, exempts the collection and the transmission means that need to use a large amount of human and material resources in the legacy system, can reduce the secondary pollution that environment is caused.Simultaneously, this system can save and adopts rubbish container (room) collection mode required in the space of every house first floor configuration garbage house, also thereby avoided the traffic contact of cram packer between each garbage house.
The refuse collection that appears as special public places such as solving apartment house on the middle and senior level, the intensive area of modern dwelling and airport, station, park of garbage collecting and transporting vacuum pipeline system provides new selection with a transportation difficult problem.At present, some advanced countries such as Sweden, the U.S. etc. receive and are obtaining bigger progress aspect Yuncheng house refuse using this type systematic, and its effect and what bring people conveniently is conspicuous has demonstrated good society, ecologic effect.But say technically, this system still is a developing system, it is a huge and complicated system that comprises many subsystems, all be still waiting development and perfect in all many-sides such as the performance of the technological design of system architecture, subsystem, specialized equipment and type selectings so that the operation of total system is coordinated more, steadily and efficient.
In this system's operational process, the rubbish that enters system from dispensing port with higher speed along with the high velocity air that produces by vacuumizing flows to central refuse collection station.After arriving at a station, separating and the rubbish that has than kinetic energy being slowed down of rubbish and air-flow is the important step that guarantees security of system, smooth running.On system architecture, then show as and device for separation of waste must be set make rubbish and burbling and cushion its kinetic energy.
The separate mode that previous system adopts is all very simple, mainly is in the place ahead of the terminal mouth of pipe of delivery duct a simple filtering net to be set to stop rubbish and make it and burbling.This design has following very significantly drawback: (1) rubbish kinetic energy can't cushion, and frequently clashes into filtering net, very easily damages filtering net and reduces its service life, need often change, overhaul, and influence continuous, the smooth running of total system; (2) mesh aperture of filtering net be difficult for to be held, and the aperture is excessive, and small garbage can not or separate not thoroughly with burbling, and the aperture is too small, and mesh very easily stops up, and not only can not make rubbish and burbling, fragile all the better filtering net; (3) can't eliminate or reduce noise, influence surrounding environment.
Because above-mentioned separate mode and device exist tangible technological deficiency, therefore, inventing a kind of brand new, the rubbish separating technology with advantages such as safety, efficient, low noise, separation are thorough, long-lived and corollary apparatus thereof replaces conventional filtering net separate mode to promote the use of significance for the safety of this system, smooth running and in bigger scope.
