System of the present invention is high low heat value separating substances in the rubbish, and it is low with high-band to handle low heat value material (like high concentration percolate, foul smell etc.) through high heating value substance combustion heat, and the treatment of wastes with processes of wastes against one another reaches the energy-conserving and environment-protective operation.

 

Description of drawings

Fig. 1 is a structural representation of the present invention.

 

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is further described.

As shown in Figure 1; A kind of application of city life garbage drying and incineration system; It comprises between rubbish storing, blower fan (model can be Y5-47), breaker (employing Taw crushing apparatus), metal sorting unit (as: magnetic separator), desiccation apparatus (as: screw press), used heat secondary desiccation apparatus (utilizing the device of hot flue gas direct contact flow material), incinerator (as: rotary kiln), residual heat using device, leachate collection pond and exhaust gas cleaner (being made up of half-dried tower, carbon-lime dry type reactor, sack cleaner etc.); Foul smell between described rubbish storing is delivered to the air inlet of incinerator through blower fan; Percolate outlet between rubbish storing connects the leachate collection pond; The outlet in leachate collection pond connects the corresponding charging aperture of incinerator; Solid-state rubbish discharging between rubbish storing is delivered to breaker, metal sorting unit, desiccation apparatus, used heat secondary desiccation apparatus and incinerator successively; The outlet of incinerator connects residual heat using device, desiccation apparatus and used heat secondary desiccation apparatus, and the waste gas outlet that connects residual heat using device connects exhaust gas cleaner.

The percolate outlet and the sludge outlet in leachate collection of the present invention pond is connected the charging aperture of atomizing lance and feed screw respectively, and the discharging opening of atomizing lance and feed screw all links to each other with the corresponding charging aperture of incinerator.

The percolate outlet of breaker of the present invention and desiccation apparatus all links to each other with the corresponding import in leachate collection pond.

The metal discharging opening of metal sorting unit of the present invention connects the waste metal retracting device.

The waste gas outlet of desiccation apparatus of the present invention connects exhaust gas cleaner (being made up of half-dried tower, carbon-lime dry type reactor, sack cleaner etc.).
