Drying, incineration and pyrolysis system and process for sick and dead poultry and livestock

Abstract

The invention discloses a drying, incineration and pyrogenation system and process for livestock dead of diseases. The system comprises a drying machine, an incineration furnace, a biochar pyrogenation furnace and a tail gas treatment device, wherein a smoke outlet of the incineration furnace is communicated with the drying machine; one path of a tail gas outlet of the drying machine is communicated with the incineration furnace; the other path of the tail gas outlet of the drying machine is communicated with the tail gas treatment device; one path of a material outlet of the drying machine is directly connected with the incineration furnace; the other path of the material outlet of the drying machine is communicated with the pyrogenation furnace; a pyrogenation tail gas outlet is communicated with the incineration furnace. According to the system and the process, ash slag after incineration can be used for preparing a building material (such as air bricks and cement filler); the remained livestock dead of the diseases, after drying, can be used for preparing biochar; dry tail gas and biochar pyrogenation gas are introduced into the incineration furnace, so that the harmlessness, minimization and recycling of the livestock dead of the diseases can be realized finally.

Description

technical field [0001] The invention relates to an environment-friendly process for treating sick and dead poultry and livestock, in particular to a drying, incineration and pyrolysis system for sick and dead poultry and livestock and a process thereof. Background technique [0002] At present, there are mainly four methods for the treatment of sick and dead animals at home and abroad: "burning, burying, boiling, and heaping". Among them, "burying" wastes land and easily pollutes groundwater; "boiling" will produce a large amount of meat residue, high-concentration wastewater and odor, which is prone to secondary pollution; "piling" takes too long and is very harmful to large animal carcasses. Not applicable; "burning" is the most thorough means to achieve the harmlessness, reduction and stabilization of sick and dead poultry and livestock, but its technology and equipment require large investment, high operating costs, and high-temperature exhaust gas cannot be fully utiliz...
