Problems solved by technology

The disadvantage of this method is that the treatment is not thorough, and there are still a large number of bones and other residues after the treatment. There is a possibility that the spores of high-temperature-resistant harmful bacteria can survive in the large bones. Acid, tyrosine and sulfur-based amino acids such as cysteine ​​are severely damaged and have low practical value

Embodiment 1

[0044] See attached figure 1 , special equipment for preparing fertilizers from animal carcasses harmlessly, the equipment includes an animal carcass crusher 1, the discharge port of the animal carcass crusher 1 is connected to an acidification transformation reaction kettle 2 with a steam heater 5, and the acidification transformation reaction kettle 2 is provided with a fatty acid separator 3 at the outlet of the fatty acid separator 3. The fatty acid outlet and the amino acid mixed solution outlet are arranged on the fatty acid separator 3. The amino acid mixed solution outlet is connected to the neutralization reactor 4, and the neutralization reactor 4 is provided with a liquid fertilizer outlet.

Embodiment 2

[0046] Refer to attached figure 1 , make use of animal corpses to prepare fertilizers. First, put the sick and dead cows into the corpse crusher for crushing. 15% of the weight of the dead cow, the amount of manganese dioxide is 1.6% of the weight of the dead cow, heat the conversion reactor through a steam generator, make the temperature in the reactor reach 120 ° C and maintain the temperature, start stirring, and the reaction time is 60 minutes After the conversion is completed, it is discharged into the separator for separation. The fatty acid in the upper layer of the liquid is used to produce chemical raw materials such as surfactants. Add a certain proportion of calcium oxide, magnesium oxide, manganese oxide, zinc oxide, adjust the PH value to 6-7.5, cool, static precipitation, a small amount of insoluble matter is solid fertilizer, and the liquid is mixed liquid fertilizer of amino acid and humic acid.

Embodiment 3

[0048] Refer to attached figure 1, make use of animal corpses to prepare fertilizers. First, put the dead pigs into the corpse crusher to crush them. 25% of the weight of the dead cow, and the amount of manganese dioxide is 1.8% of the weight of the dead cow. The steam generator is used to heat the conversion reactor, so that the temperature in the conversion reactor reaches 120 ° C and maintains the temperature, and the stirring is started. The reaction time After 60 minutes, the conversion is completed, and it is discharged into the separator for separation. The fatty acid in the upper layer of the liquid is used to produce chemical raw materials such as surfactants, and the liquids such as amino acids and humic acid in the lower part enter the neutralization reactor, and start stirring to neutralize the reaction. Potassium oxide is added to the kettle to adjust the PH value to be neutral, cooled, and a certain proportion of ferrous sulfate, manganese sulfate, zinc sulfate, ...

Abstract

The invention discloses a method for harmlessly preparing fertilizer through carcasses. The method comprises the steps that carcass fragments are firstly subjected to heat treatment conversion in an acid environment, the reaction environment is controlled to enable animal fat to be converted into fatty acid, and animal skin, fur and meat are converted into amino acid and humic acid, and animal bones are converted into water-soluble calcium salt and phosphate; the fatty acid is separated, and alkali is added to left amino acid and humic acid mixed liquid for neutralization. Special equipment of the method comprises a carcass crusher, an acidizing reaction kettle, a fatty acid separator and a neutralization reaction kettle which are connected in sequence. The method has the advantages of free of pollution, fast, thorough, efficient, high in quality and the like.

Description

technical field [0001] The invention relates to a technology for harmless treatment of animal corpses, in particular to a method and an equipment system for directly preparing multi-effect high-quality fertilizers from dead animal corpses. Background technique [0002] At present, the methods involving the harmless treatment of dead animal corpses mainly include deep burial method, incineration method, composting method, corpse pit method, chemical preparation method, and biodegradation method. The above methods all have different defects. The deep burial method, composting method, and corpse cellar method take a long time to process, and the processing is not thorough, and it is easy to cause leakage during the processing process; the incineration method consumes high energy, and resources cannot be recycled. Odor generated in the process can easily cause secondary pollution; chemical production method and biodegradation method have complex processes, high operating costs, ...
