Description
Technical field
The present invention relates to a kind of spoil processing methods, specifically, being to be related to a kind of spoil harmless treatment
Technique.
Background technology
In spite of natural death or the spoil of epidemic disease death, a variety of germs are often carried, if not handling or handling
Improper, corpse can decompose corruption, emitting offensive odor quickly, make sex pheromone pollution air, water source and soil, cause the biography of disease
It broadcasts and spreads, while directly or the people of mediate contact has the possibility of infection.This just needs timely to be handled ability
The growth of bacterium and the propagation of disease are prevented, that is, carries out spoil harmless treatment.
Traditional spoil treatment process has the following defects：
1, general producer must increase crusher before changing system, and corpse after crushing can release effluvium
Body causes secondary pollution；
2, it is all made of the method separation grease of squeezer at this stage, expression separation grease so that technological process is complicated, increases
Secondary pollution link, and grease separation is not thorough, remaining grease easily causes residue and addles.
3, imprecision between each process conversion links, there are the risks of exhaust leak.

Pa.Steam in tank is drawn to condenser by vacuum pump prevents steam from causing room air pollution by tank mouth discharge.
A2, after feeding intake, closingization tank mouth processed is decomposed after spoil is heated in tank, and is gradually made in tank
Pressure rises；
A3, stop agitating shaft, close steam in interlayer and axis, make static in tank, be layered.
Steam off prevents from boiling.
A kind of specific prioritization scheme makes in step a1 in interlayer and axis steam pressure to 0.4-0.6 megapascal.
A kind of specific prioritization scheme makes pressure inside the tank rise to 0.2-0.3 megapascal in step a2, and temperature is to 130-150 DEG C.
A kind of specific prioritization scheme, the quiescent time in step a3 are 20-60 minutes.
A kind of specific prioritization scheme, after feeding intake, closingization tank mouth processed is divided after spoil is heated in tank
Solution, and pressure inside the tank is gradually made to rise 0.3 megapascal, temperature to after 140 DEG C, stop agitating shaft, closes steam in interlayer and axis, make
Static 30 minutes in tank.
A kind of specific prioritization scheme, process B include the following steps：
B1, will change in the animal fat in tank processed and part water material importing grease knockout drum；
Situation carries out b3 when the stratification line of oil and water is in oil pump inlet pipeline in b2, observation grease knockout drum, when
When the stratification line of oil and water is higher than oil pump inlet pipeline, b4 is carried out, when the stratification line of oil and water is less than oil pump inlet pipeline, into
Row b5；
B3, unlatching oil pump squeeze into animal fat in oil storage tank, and remaining water and material residue pass through feed back in grease knockout drum
It pumps in returning tank processed；
B4, feed back pump is opened, by the part material residue and returning of water tank processed that are precipitated in grease knockout drum, until oil and water
Stratification line when being in oil pump inlet pipeline, carry out b3；
B5, continue to import water and material into grease knockout drum, until when the stratification line of oil and water is in oil pump inlet pipeline,
Carry out b3.
A kind of specific prioritization scheme, step D include the following steps：
Steam pressure rises to 0.4-0.6 megapascal in d1, making tank interlayer processed and axis；
D2, start agitating shaft and vacuum pump, start drying, all steam evaporated in drying process are whole by condenser
It is condensed into water.
Using vacuum drying, using water under vacuum conditions low boiling point the characteristics of reduce energy consumption, material had been dried in vacuo
The generated condensed device of steam is condensed into water in journey, avoids steam from being discharged into air and causes air pollution；Change tank processed and is equipped with spy material
Mouthful, dry materials degree can be observed at any time.
A kind of specific prioritization scheme, process E include the following steps：
Dry powder is delivered to cooling in convolution cooler through auger.
Convolution cooler can be quickly cooled to room temperature and be packed.
Spoil harmless treatment process tank of the present invention has broken, change system, grease separation, vacuum drying work(
Can, the animal fat changed in tank processed and part water material are entered by multiple conduits and carry out secondary stratification point in grease knockout drum
From the grease of secondary separation reaches requirement, avoids the pollution to ambient enviroment between process conversion, and each process energy consumption is reduced, object
Material can reuse after processing, energy conservation and environmental protection.
