Embodiment

[0027] Embodiment: a kind of treatment process of dead pigs, such as figure 1 . This process includes the following steps:

[0028] Step 1, using a shredder to shred the sick and dead pigs;

[0029] Step 2, using a high-temperature cooking tank to perform high-temperature cooking on the chopped sick and dead pigs, the cooking temperature is kept at 190-220°C, cooking for 5 hours, and the treated matter in the high-temperature cooking tube is homogenized;

[0030] Step 3, using a solid-liquid separator for solid-liquid separation, using an oil-water separator for liquids to separate oil and water, and separating solid organic matter, bio-oil, and water after high-temperature cooking;

[0031] Step 4: Send the solid organic matter separated in Step 3 to the airflow dryer for drying, and then send it to the carbonization furnace for high-temperature anaerobic closed-type carbonization to form biochar. The carbonization temperature is not lower than 400°C, and the exhaust gas fr...

Abstract

The invention related to a treatment process of livestock died of epidemic diseases. The invention solves problems which disease the transmission and the environmental pollution caused by a improper treatment of existing livestock died of epidemic diseases while existing treatment ways have a high cost and a low energy utilization rate. The process comprises following steps: step 1: livestock died of epidemic diseases will be cut up by a chopping machine; step 2: chopped livestock are cooked under high temperature in a closed container in order for the homogenization of dead livestock; step 3: solid organic matters, biological oil and water after high-temperature cooking are separated by a separator; step 4: solid organic materials separated in step 3 are delivered to a charring furnace for the high-temperature, anaerobic and closed charring to form charcoal; step 5: water separated in step 3 is delivered to a biogas digester for biogas fermentation to create biogas; step 6: biological oil separated in step 3 is used as the heating fuel of the high-temperature cooking in step 2 and the charring in step 4. The complete process system in the invention has a good closure, reducing risks in the disease transmission; reducing the consumption of fuel provided externally.

Description

technical field [0001] The invention relates to a process for treating solid waste, in particular to a process for treating dead poultry and livestock due to epidemic diseases. technical background [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 the dead poultry and livestock, it is necessary to deal with them in time to avoid epidemics, environmental pollution and even the entry of diseased poultry and livestock into the market. The poultry and livestock that died of the epidemic disease contain pathogenic bacteria, so in the process of processing, it is necessary to ensure the closure as much as possible to avoid infection and environmental pollution, and in the process of processing, it is necessary to minimize energy consumption and reduce processing costs. Tradit...
