Harmless treatment method and treatment system for dead poultry and livestock

Abstract

The invention discloses a harmless treatment method of dead livestock and a treatment system thereof. When the dead livestock passes a high-temperature hydrolysis drying unit and a hydrolysis waste gas treatment unit, saturated vapor is used for directly contacting with the dead livestock, disease organisms are completely killed by dint of dual effect of high temperature and high pressure, and the environmental pollution caused by the dead livestock is radically solved; by-products, such as industrial grease and meat bone cakes, are extracted by a grease squeezing unit and a grease purifying and separating unit to achieve effective resource recycling; and exhausted gas satisfies the environmental protecting requirements by a hydrolysis waste gas condensing unit and a secondary tail gas treatment unit. The method and the system radically solve such technical problems as environmental pollution due to the flowing of the dead livestock into the market, resource waste caused by the harmless treatment process and higher treatment cost, reduce the harmless treatment investment cost of the dead livestock, increase the enterprise economic benefit, effectively protect the ecological environment, and lay the solid foundation for the harmless treatment of the dead livestock.

Description

Technical field:

[0001] The invention relates to a treatment method and a treatment device for sick and dead livestock and poultry, in particular to a harmless treatment method and a treatment system for sick and dead livestock and poultry, belonging to the technical fields of environmental protection and resource reuse. Background technique:

[0002] my country is a big country in poultry and livestock breeding, and its breeding scale ranks among the top in the world. In the process of poultry breeding, there is a certain mortality rate due to reasons such as weather and epidemic diseases. For dead poultry and livestock, it is necessary to conduct harmless treatment in a timely manner to avoid epidemics, environmental pollution, and even diseased poultry and livestock entering the market and causing food safety accidents. Poultry and livestock killed by traditional epidemic diseases are generally treated by deep burial, incineration or fermentation: ①Deep burial treatment ...

Embodiment 1

[0026] Embodiment 1: a kind of harmless treatment method of dead poultry and livestock, its specific steps are as follows:

[0027] ①Disposal of sick and dead livestock and poultry: Use sealed vehicles to collect and transport the sick and dead livestock and all waste from each farm to the harmless treatment workshop. After the vehicle is disinfected through the automatic spraying and disinfection channel, the sick and dead livestock Poultry and waste are unloaded in the low-temperature cold storage pool 2;

[0028]②High-temperature and high-pressure hydrolysis drying: A certain amount of sick and dead livestock and poultry and waste are transported to the high-temperature and high-pressure hydrolysis and drying integrated machine 4 through the belt conveyor 3, and sterilized at a temperature of 300-350°C for 4-5 hours;

[0029] ③ Hydrolysis waste gas treatment: The waste gas generated after sterilization is input into the hydrolysis pressure relief dust collector 22 through t...
