Semicoke (garbage carbon), in carburization zone carbonization heat release, produces high-temperature flue gas and lime-ash.Carbonization release
Heat energy is absorbed by energy-accumulation material and stores, and when adding house refuse in stove, domestic garbage pyrolysis is absorbed
Heat provided by carburization zone and energy storage material heat release, the thermal discharge of carburization zone is more than the warm increasing upper rubbish
Desorbing heat, pyrolytic reaction just can go on.It is thus desirable to ensure the carburizing temperature of carburization zone.At carbon
The temperature recorded, equipped with temperature transmitter, is input to automatically control by change layer with analog quantity (0-24mA) signal
In systematic microprocessor processed, the temperature being controlled carburization zone by the analog quantity output signals of microprocessor is regulated
The state of valve, controls the temperature of carburization zone.The temperature of carburization zone controls at 450 DEG C～500 DEG C.
Pyrolytic layer
Rubbish, after dehydration, continues heat absorption, and when temperature is more than 200 DEG C, organic matter in garbage divides
The side chains such as methyl in son, ethyl start fracture, slough carbon and hydrogen respectively, generate methane, hydrogen and
The micro-molecular gas such as other Hydrocarbon.Along with the further rising of temperature, take off the Organic substance of side chain
Main chain rupture, generate many small-molecule substances.The pyrolysis of rubbish is not necessarily to certain time
Sequence is carried out, and many reactions all intersections are carried out.The produced little molecule of pyrolysis is through condensation reaction again
It is reassembled into the Organic substance of macromole, and the Organic substance of these macromole may also pass through cracking and again becomes
For the Organic substance of little molecule, so the pyrolysis of rubbish is extremely complex physics, a chemical process.?

During domestic garbage pyrolysis, on the one hand moisture evaporates heat to be absorbed, and hinders the transmission of heat,
Extend pyrolysis time；On the other hand the evaporation rate of moisture is faster than organic pyrolysis rate, works as moisture
After separating out rapidly, in rubbish, remaining Organic substance density declines, and is conducive to shortening pyrolysis time.
Along with the increase of moisture in rubbish, actual disposal ability declines, and energy expenditure increases.Actual rubbish
Moisture content in rubbish is the highest, can reach more than 50%, and the moisture in rubbish not only reduces the heat of gas
Value, and add the heat consumption of garbage disposal.For the rubbish that moisture content is high, blending can be used
The method of dry rubbish is neutralized, and reduces the moisture content of rubbish.The method that additionally can use solar energy heating
(optional), improves the calorific value of evaporation layer, the moisture of rapid evaporation rubbish, can guarantee that and processes the smooth of technique
Carry out.
