Abstract

The invention discloses an anaerobic rubbish decomposition technology which relates to the technical field of rubbish decomposition. The technology comprises a diesel combustion engine, air ducts for a secondary combustion room, the secondary combustion room, a vertical fire grate, a spray cooling tower, a desulfurization dust removal tower, heat exchange equipment, a low-temperature plasma air purifier, cloth bag dust removal equipment, an optical catalytic converter, a fan and a water pump, wherein the diesel combustion engine is connected to a main-furnace cracking furnace; the secondary combustion room and the vertical fire grate are disposed inside the main-furnace cracking furnace; the secondary combustion room is connected to the spray cooling tower; the air ducts for the secondary combustion room are connected to two sides of the secondary combustion room; the spray cooling tower, the desulfurization dust removal tower, the heat exchange equipment, the low-temperature plasma air purifier, the cloth bag dust removal equipment, the optical catalytic converter and the fan are connected successively; and the water pump is connected to the desulfurization dust removal tower and the heat exchange equipment respectively. The technology disclosed by the invention has the advantages that reclamation, harmlessness and minimization of rubbish become obvious; and hundreds of millions of square meters of landfill lands, tens of billions of renminbi of rubbish treatment service fees, hundreds of billions of renminbi of rubbish treatment equipment investments and millions of tonnage of fuel coal can be saved every year for a country.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to an anaerobic garbage decomposition process. Background technique [0002] Anaerobic garbage pyrolysis is the process of thermal energy conversion of garbage. As far as its combustion is concerned, since the combustible part in garbage includes volatile and non-volatile, it has two combustion forms, one is surface combustion, and the other is combustion. It is decomposition and combustion. In addition, as far as the waste incineration process is concerned, there are mainly three stages of medium and low temperature baking, that is, dehydration, dry distillation and high temperature carbonization and burnout, and finally cooling to ash powder. In order to shorten the time of anaerobic pyrolysis, a higher temperature (1000-1300°C) for the secondary combustion of the central device is generally used, so that the high-temperature flue gas can dry and dehydrate the upper gar...
