Abstract

The invention relates to an integrated harmless dead livestock treatment system and a process thereof. The integrated system comprises a drying device, an incinerating device, a pyrolysis device, a dust collection device, a tail gas treatment device and a circulating fan, wherein the air outlet of the incinerating device is connected with the air inlet of the drying device, the drying device is connected with the pyrolysis device and is connected with the dust collection device and the tail gas treatment device in sequence; the air outlet of the pyrolysis device is connected with the incinerating device. The system adopts a water wash and urea / H2O2 wet process as well as the desulfurization and denitration process and biological carbon adsorption process for combined treatment of the dried tail gas, not only is the easily water dissolved component absorbed, the usage of chemical reagent in subsequent treatment steps reduced, the temperature of reaction liquid lower and the work safety improved, and also SO2, H2S, NOx and NH3 gases can be removed simultaneously, ammonium sulfate can be recycled and no secondary pollution is caused.

Description

technical field [0001] The invention relates to the technical field of treatment of sick and dead poultry and livestock, in particular to a complete system and process for the reduction and harmless treatment of sick and dead poultry and livestock. Background technique [0002] my country is a large livestock and poultry breeding country, and the scale of breeding ranks among the top in the world. Animals die due to environmental adaptability and diseases during the breeding process. Harmless treatment of it has become an urgent problem to be solved in the current epidemic prevention and control work. At this stage, in the harmless treatment of sick and dead poultry and livestock, the more mature technologies mainly include "burning, burying, boiling, and heaping" 4 methods. However, the four methods have their own disadvantages: "burying" is too wasteful of land, and it is easy to pollute groundwater; "boiling" will produce a large amount of meat residue, high-concentration...
