Garbage pyrolysis gasification treatment method

Abstract

The invention discloses a garbage pyrolysis gasification treatment method. The method comprises the following steps: putting garbage into a garbage pyrolysis gasification furnace for storage, drying, pyrolysis gasification and combustion treatment; the flue gas of the garbage pyrolysis gasification furnace is introduced into a flue gas combustion device for secondary combustion; flue gas obtained after secondary combustion is introduced into a flue gas purification device to be purified; wherein the flue gas introduced into the flue gas combustion device for combustion is introduced from the upper end of a garbage storage chamber, the upper end of a garbage drying chamber and the upper end of a garbage pyrolysis chamber of the garbage pyrolysis gasification furnace respectively, and is jointly introduced into the flue gas combustion device for oxygen distribution for mixed combustion. According to the method disclosed by the invention, flue gas is led out from different positions of the garbage pyrolysis gasification furnace respectively, and then oxygen-added mixed combustion is carried out in the garbage combustion device, so that high-temperature and efficient combustion of the flue gas is facilitated; and adjustment of smoke is facilitated, so that efficient treatment of garbage in the furnace is facilitated.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a garbage pyrolysis gasification treatment method. Background technique [0002] With the continuous improvement of living standards, people's quality of life has been greatly improved, and at the same time, the generation of domestic waste is also increasing. The disposal of a large amount of urban and rural domestic waste every day has become a difficult problem. One way is to carry out landfill, bury domestic waste in the landfill for centralized treatment, but with the continuous shortage of land resources, the land demand for landfill continues to increase, and the way of landfill is difficult to continue; Moreover, landfill is only a temporary treatment method and cannot eliminate garbage. It takes tens or even hundreds of thousands of years to degrade garbage by itself. At the same time, landfill may cause land pollution and water and soil pollution. Therefore,...
