A new type of waste pyrolysis gasifier发布日期:2020-04-27 17:15 浏览次数:

The pyrolysis gasification reaction mode of fixed bed thick material layer is adopted in the pyrolysis gasification chamber of the device. The pyrolysis gasification furnace is divided into drying layer, gasification layer, combustion layer and burnout layer. The pyrolysis chamber is of fire-resistant and heat-insulating structure, and the furnace chamber is kept in constant temperature state to burn without abnormal low temperature.
2. Good heat insulation effect, strong heat storage capacity of fire-resistant insulation layer, no oil in normal operation, good economic benefits.
3. The first stage is the pyrolysis gasification and combustion in anoxic state, which is carried out in the first combustion chamber. The working temperature is controlled at about 600-850 ℃, so that the nonvolatile combustibles in the garbage are completely burned, and the combustible volatile gases enter the second combustion chamber; the second stage is the combustion in the second combustion chamber, The working temperature is controlled at 850-1100 ℃, the high-temperature flue gas is generated by full combustion, and the retention time of high-temperature flue gas is more than 3-4 seconds, which can fully oxidize the organic matters in the waste. It has controlled the generation of secondary pollution and put an end to the generation of toxic and harmful gases, especially dioxins. Good combustion performance. Avoid secondary pollution, suitable for the treatment of low and medium calorific value waste, long service life.
4. The furnace is equipped with a high-temperature and corrosion-resistant rotary slag breaking mechanism of ductile iron material, which can break large coking objects and discharge them. There are gaps on both sides of the furnace, which can pass large objects.
5. During the operation of the main furnace, the adjustment range of the forced draft fan and induced draft fan shall ensure that the system is in a negative pressure state, without backfire, to avoid the escape of flue gas.
