Embodiment Construction
[0022] The present invention will be further described in detail below in conjunction with specific embodiments.
[0023] A microwave vacuum pyrolysis method for combustible solid waste, comprising the steps of:
[0024] (1) Vacuum treatment of combustible solid waste to reach a state of negative pressure, and the degree of vacuum is kept at least -30KPa.
[0025] (2) Heating the combustible waste after vacuum treatment. The heating method adopts microwave heating to 580-640 ℃. During the heating process, the vacuum degree should always be maintained to reach -30KPa to -70KPa, and the gas generated by pyrolysis should be heated. It is extracted and discharged after being purified by the flue gas purification system; the heating time varies according to the weight of the combustible solid waste. The reference value is: the heating time of 2 kg of pure cotton cloth is 22 minutes.
[0026] (3) Stop heating, and the temperature of combustible solid waste will continue to rise. De...
