Garbage carbonization combustion treatment technology

Abstract

The invention relates to a garbage carbonization combustion treatment technology. The garbage carbonization combustion treatment technology comprises the steps that garbage is conveyed onto a drying fire grate of a drying chamber; the garbage on the drying fire grate is subjected to dewatering and drying through ascending hot airflow generated during combustion of garbage in a combustor and hearthheat radiation; the drying fire grate is opened, the garbage subjected to dewatering and drying falls onto a carbonization fire grate of a carbonization chamber, and high-temperature oxygen-poor carbonization pyrolysis is conducted through the flame temperature and high-temperature flue gas during combustion of the garbage in the combustor; the carbonization fire grate is opened, the carbonized garbage falls onto a combustion fire gate of the combustor to be combusted; flue gas generated during combustion of the garbage in the combustor enters a burnout chamber for secondary combustion; the flue gas subjected to secondary combustion is fed into a flue gas treatment system after being cooled through a rapid cooling chamber; and the flue gas is exhausted after being processed through a dustremoval device, a deacidification device and a desulphuration device. Through the garbage carbonization combustion treatment technology, the technical problems that existing small-size garbage treatment equipment is low in garbage treatment efficiency and automation degree, incapable of reaching the exhaust gas emission standard, and the like can be solved.

Description

technical field [0001] The invention relates to the technical field of domestic waste treatment, and more specifically, to a waste carbonization and combustion treatment process for miniaturized waste treatment equipment. Background technique [0002] The existing process methods applied to small waste treatment equipment mainly include direct combustion method and heat treatment combustion method. The direct combustion method is to directly burn the primary domestic waste as fuel, which is an original treatment process; the heat treatment combustion method is to perform a preliminary heat treatment on the primary domestic waste to improve the combustion conditions of the waste, and then burn the treated waste. [0003] The processing route of a class of domestic waste represented by the direct combustion method mainly has the following problems: 1. Poor waste burning conditions, 2. Low degree of reduction, 3. Poor harmless effect 4. Concentration of flue gas pollutants Hig...
