Garbage pyrolysis gasification incineration system and method

Abstract

The invention relates to a garbage pyrolysis gasification incineration system and method. The garbage pyrolysis gasification incineration system comprises a garbage transfer pool, a drying device, a pyrolysis gasification device and a tail gas treatment device, a feeding port of the drying device is connected with the garbage transfer pool through a feeding device, a discharging port of the dryingdevice is connected with a feeding port of the pyrolysis gasification device, and the incineration system further comprises a heat exchange device; an exhaust port of the pyrolysis gasification device communicates with a main gas inlet of the heat exchange device, a main gas inlet of the drying device communicates with a main gas outlet of the heat exchange device, a main gas inlet of the tail gas treatment device communicates with a main gas outlet of the drying device, and an air extractor is further arranged in the garbage transfer pool; and an auxiliary gas inlet of the heat exchange device communicates with an auxiliary gas outlet of the air extractor, an auxiliary gas inlet of the drying device communicates with an auxiliary gas outlet of the heat exchange device, and an gas inlet of the pyrolysis gasification device communicates with an auxiliary gas outlet of the drying device. The garbage pyrolysis gasification incineration system has the effects that the heat of high-temperature flue gas can be recycled, and the energy consumption of the whole system is reduced.

Description

technical field [0001] The invention relates to the technical field of domestic waste treatment, in particular to a waste pyrolysis gasification incineration system and method. Background technique [0002] Due to the current overcapacity, the cost of waste recycling in daily life is too high, people are unwilling to recycle, and it has become garbage that can be seen everywhere. Now the conventional means of garbage disposal is landfill. For landfill, each city covers an area of ​​tens of acres of garbage every day. As the land becomes less and less, landfill has become an urgent alternative. As a result, waste incineration treatment methods have emerged. Although a large amount of toxic and harmful gases will be produced during the process of waste incineration, pollution can be significantly reduced through post-treatment tail gas. [0003] At present, the process of waste incineration is complicated, the treatment efficiency is low, and the heat energy of high-temperatu...

[0002] Due to the current overcapacity, the cost of waste recycling in daily life is too high, people are unwilling to recycle, and become garbage that can be seen everywhere

Now the conventional means of garbage disposal is landfill. For landfill, each city covers an area of ​​tens of acres of garbage every day. As the land becomes less and less, landfill has become an urgent alternative. As a result, waste incineration treatment methods have emerged. Although a large amount of toxic and harmful gases will be produced in the process of waste incineration, the pollution can be significantly reduced through post-treatment tail gas.

[0003] At present, the process of waste incineration is complicated, the treatment efficiency is low, and the heat energy of high-temperature flue gas cannot be fully utilized, which makes it difficult for the exhaust gas to meet environmental protection standards.
