Process flow and treatment system for harmless treatment of sick and dead poultry and livestock

Abstract

The invention discloses a harmless treatment technological process for dead poultry and livestock. The harmless treatment technological process comprises steps as follows: 1), automatic loading and breaking; 2), heating treatment; 3), dry melting; 4), waste gas treatment; 5), solid-liquid separation after melting. According to the technological process, hot oil circularly flows on the periphery of a melting barrel, so that the heating requirement is met, and the condition required by the dry melting is met; waste gas produced in the melting process is concentrated and discharged to a water vapor inlet of a water vapor chamber through a pipeline and is pyrolyzed by heat produced in an oil path, thereby meeting the emission requirement; the heat energy demand of a melting machine and the water vapor chamber is met by a combustion furnace in a single heating process, the energy is saved, the occupied space is reduced, and energy conservation and environmental protection are realized; after hot air entering the combustion furnace from an inlet is discharged from an outlet after circulation, part of the hot air is discharged into a high-temperature melting barrel through a pipeline, the melting efficiency is improved, the other part is discharged into a drying barrel, the heat energy recycling effect is realized, more energy is saved, and resources are sufficiently recycled.

Description

technical field [0001] The invention belongs to the technical field of treatment of sick and dead poultry and livestock, and in particular relates to a process flow and a treatment system for harmless treatment of sick and dead poultry and livestock. Background technique [0002] It is common for livestock and poultry to die of disease or disaster. However, if the dead livestock and poultry carcasses are not handled properly or discarded everywhere, it is very easy to cause pollution of the environment, pens, and water sources, and the spread of disease sources, endangering the lives of the people and livestock. The discarded corpses of sick and dead livestock and poultry will be pecked by some birds and bitten by some domestic dogs, wild dogs and wild animals, and dragged away, which not only pollutes the environment but also is a source of infection. Gradually rotting, rotting, and stinking. The foul smell pollutes the air and affects the health of humans and animals. The...

AI Technical Summary

Problems solved by technology

The bacteria and viruses carried by the discarded sick livestock and poultry carcasses will spread rapidly through the air or other channels. If it is a major animal epidemic or zoonotic disease, it will cause a major animal epidemic or zoonotic disease, and the lives of humans and animals will be safe. will be threatened, the economy will suffer serious losses, and the development of animal husbandry will be affected.

[0003] Therefore, the treatment of sick and dead poultry has always been a thorny issue in the breeding industry. The traditional treatment methods include deep burial, incineration, and fermentation. The toxic gas produced in the process is easy to pollute the environment; fermentation treatment requires a special fermentation tank, and the fermentation cycle is long, and the unpleasant smell is easy to emit during the fermentation process, which seriously pollutes the surrounding environment, and the fermentation capacity of the fermentation tank is limited. There are defects in the method, and there are chemical machines specially used to deal with sick and dead poultry and livestock on the market. The existing process of using chemical machines to treat poultry carcasses usually separates the medium oil and water vapor chambers for heating. The thermal energy utilization of this treatment process is insufficient, the energy consumption is large, and the energy consumption cost required for the treatment of poultry carcasses is high
