A continuous pyrolysis carbonization treatment method and device for farm solid waste

Abstract

The invention relates to a continuous pyrolysis and carbonization treatment method and device for solid waste in farms. The solid waste crushing part: crushes the solid waste; High-temperature flue gas is obtained indoors; pre-treatment part: put the crushed solid waste into the pre-treatment chamber, and introduce high-temperature flue gas from the heating part for heating; carbonization treatment part: send the pre-treated solid waste into carbonization The treatment chamber is heated by introducing the high-temperature flue gas from the heating part; the gas treatment part: collects the gas phase products generated in the pretreatment and carbonization treatment respectively for condensation to obtain condensed liquid and non-condensable gas; the gas utilization part: converts the non-condensable gas Introduced into the combustion chamber of the heat supply part for combustion; the invention also provides a device for realizing the method. The invention has the advantages of simplified process, simple equipment structure, stable and reliable operation, short carbonization time, high energy utilization rate and the like.

Description

Technical field: [0001] The invention belongs to the technical field of organic waste treatment, and more specifically relates to a continuous pyrolysis carbonization treatment method and device for farm solid waste. Background technique: [0002] With the development of agricultural science and technology and the increase of regional breeding density, livestock and poultry manure and waste water produced by breeding places have caused serious harm to the ecological environment and water quality in the surrounding countryside. Especially in recent years, viruses such as bird flu have spread. Timely and harmless treatment, especially improper treatment of dead livestock and poultry corpses, livestock and poultry manure and waste feed, can easily cause the occurrence and spread of major animal diseases, and even cause environmental pollution. Environmental pollution and health hazards caused by farm waste The issue has received much attention. Recently, the harmless treatment...

Problems solved by technology

In the actual use process, according to the applicant's report, this set of devices can complete the pyrolysis and carbonization of meat corpses well, but there are certain problems: the drying and carbonization of meat corpses in this device are integrated in the pyrolysis tank Because the meat corpse contains a lot of water, it needs to consume more heat to evaporate the water in the meat corpse during the drying process, resulting in low carbonization temperature of the meat corpse, long carbonization time, low recovery rate of carbides, and dryness of the meat corpse. The heat supply for carbonization and carbonization cannot be adjusted according to actual needs, the overall process and corresponding structure of the equipment are complicated, the cost is high, and the energy utilization rate is low
