Meat corpse continuous pyrolysis carbonization method and device

Abstract

The invention relates to a meat corpse continuous pyrolysis carbonization device which comprises a preheating room (1), a carbonization room (2), a cooling room (3), a pyrolysis gas recycling unit (4) and a charging basket (5), wherein the preheating room (1), the carbonization room (2) and the cooling room (3) are sequentially connected; furnace doors are arranged for the preheating room (1), the carbonization room (2) and the cooling room (3); an air flue is formed between the outer wall of each furnace pipe and the inner wall of each furnace body; a combustion room (42) is arranged at the side of a second furnace body (20), and an exhaust gas discharge pipe (43) is communicated with a second furnace pipe (21) and the combustion room (42); a high-temperature flue gas importing pipe (44) is used for discharging gas in a second air flue (27); a first material pusher (16) feeds the charging basket (5) from a first feeding end (13) and pushes the charging basket (5) from a third discharging end (33); the charging basket (5) is used for placing meat corpses. The device provided by the invention solves the problem that the equipment quantity is great and the whole structure is complex and has the advantages of being high in automatic degree, simple in process, simple in equipment structure and the like.

Description

Technical field: [0001] The invention relates to the technical field of organic waste treatment, in particular to a method and device for continuous pyrolysis and carbonization of carcasses. Background technique: [0002] In recent years, with the development of agricultural technology and the increase of regional breeding density, as well as the spread of viruses such as bird flu, the number of animal deaths has increased year by year, and a series of environmental pollution and health hazards caused by dead livestock and poultry have attracted much attention. If the dead livestock and poultry are not treated in a timely and harmless manner, it is easy to cause the occurrence and spread of major animal diseases, and improper treatment will cause environmental pollution. Recently, the harmless treatment of sick and dead livestock and poultry has gradually been adopted by the industry as a more effective resource-based treatment technology.

AI Technical Summary

Problems solved by technology

[0005] (1) In this device, the pyrolysis chamber, the cooling chamber and the tractor used to collect the pyrolysis and carbonization products are set independently of each other, the number of equipment is large, and the overall structure is complicated, so it is impossible to realize the integration of thawing, pyrolysis, carbonization and cooling treatment of meat corpses Chemical, automatic, and continuous completion, the overall pyrolysis treatment efficiency is low and energy consumption is large

[0006] (2) Although the preheating and pyrolysis carbonization in the device are integrated in the pyrolysis tank, which speeds up the processing efficiency to a certain extent, the heat supply for preheating and pyrolysis carbonization cannot be adjusted according to actual needs. The residual heat of the thawing can preheats and thaws the frozen meat carcasses. However, since the temperature of the pyrolysis tank is about 500°C at this time, the inside of the carcasses has not been thawed yet, and the outside has been dried or even carbonized, resulting in insufficient pyrolysis treatment. In the complete situation, that is, the phenomenon of "cooking", the carbonization effect is not good

[0007] (3) After the pyrolysis and carbonization is completed, the temperature in the pyrolysis chamber needs to be lowered to below 500°C before opening the furnace door and pushing out the basket, and then entering a new basket to be processed. The temperature loss of the pyrolysis chamber is relatively high. Large, to a certain extent it wastes a part of the temperature in the pyrolysis chamber
