Description

The method of the harmless processing of a kind of disease livestock and poultry through engineering approaches and recovery energy

Technical field

The present invention relates to energy technology and environmental technology field, the method for the harmless processing of especially a kind of disease livestock and poultry through engineering approaches and recovery energy.

Background technology

China is Production of Livestock and Poultry and consumption big country, and the national live pig amount of delivering for sale was approximately 6.67 hundred million in 2011, approximately 6,000 ten thousand of beef cattles, approximately 200,000,000 of mutton sheeps, poultry 20,000,000,000 plumages.Minimum mortality (poultry 2%, fowl 5%) with livestock and poultry calculates, and has 1,334 ten thousand pigs every year at least, 1,200,000 beefs, and 4,000,000 mutton sheeps, 1,000,000,000 plumage poultry are dead, and the health and the problem of environmental pollution that cause therefrom receive much concern.If the untimely harmless treatment of dead livestock and poultry not only pollutes the environment, but also easily cause generation and the propagation of great animal epidemic, the serious threat mankind's health.Particularly in recent years, the acute epidemic situations such as bird flu, aftosa, rabid ox disease, Streptococcus suis, rabies are frequent outbreak of epidemic at home and abroad, and human health has been consisted of great threat.

The dead livestock and poultry great majority occur in vast rural area and plant, and present main processing mode is buried and burns.Adopt buried mode to process, need to consume a large amount of land resources, and must be buried below 1.5 meters, even reached this degree of depth, also can't reach innoxious requirement.Sepage meeting polluted underground water source after dead livestock and poultry rots, and some virus can be survived the secondary pollution that easily causes for a long time with bacterium in soil.Adopt the mode of burning to process, can produce the pernicious gases such as flue dust, carbon dioxide, bioxin, environmental and human health impacts is worked the mischief.

Summary of the invention

Purpose of the present invention will solve the deficiency that above-mentioned technology exists just, and provide the method for the harmless processing of a kind of disease livestock and poultry through engineering approaches and recovery energy, the method not only can solve the problem of environmental pollution that is caused by dead livestock and poultry, can also realize simultaneously the recovery energy of dead livestock and poultry, whole process safety is reliable, can not produce discarded object, not have secondary pollution, have important practical significance and good using value.

The present invention solves the technical scheme that its technical problem adopts: the method for the harmless processing of this disease livestock and poultry through engineering approaches and recovery energy, and the method step is as follows:

(1) directly dead livestock and poultry is sent in the high-temperature kettle with the airtight collecting cart that meets the epidemic prevention requirement, added a certain amount of water or do not add water, then seal high-temperature kettle, heat with high temperature heat source; Hierarchy of control temperature at 100-200 ℃ and pressure in the 1-15atm(absolute pressure), 1-5 hour heat time heating time;

(2) after above-mentioned heating finishes, be cooled to 30-90 ℃, adopt to stir solid material is disperseed, then allow its natural subsidence;

(3) natural subsidence 0.1-1 hour, open the high-temperature kettle bottom valve, the solid matter of lower floor is imported solid-liquid separator separate, the solid matter after the separation is processed into calcareous fertilisers; Separate the liquid remaining liquid in high-temperature kettle that obtains, be transported to oil water separator;

(4) liquid is oil water separator static layering 0.1-2 hour, with the grease overflow on upper strata to oil storage tank; Lower floor's mass transport is to the biogas size-mixing tank;

(5) grease as feedstock oil for the preparation of biodiesel; Material in the biogas size-mixing tank enters marsh gas anaerobic fermentation apparatus, produces biogas, and directly burning is used, or is used for generating or preparation vehicle fuel after purifying.

As preferably, described dead livestock and poultry is the livestock and poultry such as the pig that dies of illness, ox, sheep, chicken, and the higher livestock and poultry of fat content such as pig particularly die of illness.

As preferably, described solid matter is bone etc.

As preferably, a certain amount of water of described adding, its weight be dead livestock and poultry 1-5 doubly.

As preferably, described high temperature heat source is steam, conduction oil, microwave or electricity.

As preferably, adopt steam as high temperature heat source, adopt indirect steam heating or open steam heating.

As preferably, the described type of cooling adopts water quench or naturally cools off.

As preferably, described solid-liquid separator adopts drum screen, centrifuge or screen pack etc.

The effect that the present invention is useful is: the present invention turns waste into wealth dead livestock and poultry by the dead livestock and poultry HTHP is added thermal release, realizes harmless treatment and recovery energy.The resulting grease of separation process can be used as feedstock oil, for the preparation of biodiesel; Bone can be processed into calcareous fertilisers; Rest materials enters the biogas size-mixing tank and prepares biogas, and biogas can be used to burning, generating or preparation vehicle fuel.Whole process safety is reliable, equipment investment is little, can not produce discarded object, can not cause secondary pollution, has important practical significance and good using value.
