2. burn and the burning electricity generation method: the recycling treatment that has realized rubbish; But the method can produce a large amount of pernicious gases, and the method has been brought great shortcoming; And merely burn the meeting atmosphere pollution, burning away the refuse is difficult to eliminate dioxin, the toxic and harmful atmosphere pollution; If the processing pernicious gas, investment and operating cost can be quite expensive.And, at present the domestic waste complicated component, calorific value is low, the organic matter water content is too large, needs to add a large amount of auxiliary fuels.
Currently think that garbage combustion device has mechanical grate furnace preferably, this mechanical kiln grate furnace probably is divided into the process that crude waste burns: crude waste is by dry dryer section, then pass through the burning zone of gasification, and combustion, pass through again the burning segment of flame combustion, rear static combustion, final combustion are slag.Dryer section in this mechanical kiln grate furnace has been opened up one " green channel " to cold air, and the pernicious gas that burning produces can be discharged among the atmosphere by this passage.
At present, combustion furnace all is the lower air of supplying with facing up burning usefulness from incinerator, and air enters from below behind the incinerator cooling of furnace slag, and air then is heated, and makes progress and fuel burns together.Such as wood fuel, be subject to the heating of fire after then falling from above, at first be that temperature raises, dry afterwards, then burning, combustion decomposition goes out acetic acid, wood tar, potassium chloride, potassium sulfate etc., remaining is charcoal, and what charcoal burning was remaining is lime-ash, discharges from furnace bottom.If coal then may produce coal tar, sulfur dioxide, sulfur trioxide, nitrogen oxide; If plastics may produce the extremely malicious macromolecular compounds such as dioxin.
Summary of the invention
The objective of the invention is to overcome incomplete combustion that processing method causes and the burning of adding rubbish in the prior art from the top of incinerator and produce a large amount of pernicious gases, provide a kind of refuse disposal installation to push the processing method of rubbish from the below of incinerator, do not have noxious gas emission thereby burning is reached fully.
