Description
Technical field
The invention belongs to poultry excrement and urine disposal and utilize field, particularly to a kind of cattle manure recycling system, more
In particular to a kind of recycling system preparing cattle bed padding with cattle manure for raw material.
Background technology
Cattle manure, as a kind of animality organic fertilizer, is the resource of a kind of preciousness, and cattle feed intake is big, every day institute
The fecaluria discharged is more than other domestic animals, and an Adult Bovine, Fecal wastes amplitude is 28.4-48.1kg the most round the clock, often
Voided volume amplitude is 6.5-14.1kg round the clock, and substantial amounts of cattle manure urinates not only contaminated air and water source, and occupies
Large stretch of soil, is the most at home and abroad mainly used in compost and prepares biogas in the processing method of cattle manure.
Use the processing method of compost, although cattle manure processes through biochemical processing technique and makes green organic manure
The most relatively environmental protection, but due to cattle manure quality consolidation, composition is similar to pig manure, and in excrement, water content is high,
Aeration is poor, decomposes slowly, and fermentation temperature is low, and fertilizer efficiency is slow, therefore practising cattle manure is called " cold manure ".
Prepare the processing method of biogas, ferment in directly a large amount of cattle manures being placed on anaerobic fermentation equipment big to produce
The biogas of amount, after fermentation, the processing method of usual remaining residue is difficult to satisfactory.
For solving the problems referred to above, occur in that various solution, such as, Chinese patent literature at present
Disclosing a kind of novel cattle excrement and urine treating system [patent No. ZL201320634426.3], it is by manure lagoon, solid
Liquid separator, exsiccator, pulverizer, methane-generating pit form, and utilize excrement dirt flushing pump that cattle manure be will pass through raw material
Conveying pipe enters described solid-liquid separating machine and carries out solid-liquid separation, and isolated solid-state cattle manure is just by solid-liquid separating machine
Discharging opening output, enter exsiccator be dried process, dried cattle manure just through crushing system process
Becoming cattle bed padding, isolated liquid is located at the methane-generating pit of underground by separating the entrance of liquid outlet tube.
Technique scheme isolated solid-state feces can be as cattle bed padding, and isolated liquid achieves zero
Discharge, will not be to environment.But there are at least two point defects in it: 1, to the utilization rate of feces also
The highest, do not carry out effective anaerobic fermentation flow process and the biogas just for biogas slurry generation utilizes, therefore
The biogas produced is very limited, and the particularly utilization to the biogas produced is short of especially, can not form one
The recycling system of circulation, the biogas i.e. utilizing feces self to produce is supplied in the heat drying of solid-state feces；
2, due to biogas from anaerobic ferment devices output time, particularly when middle temperature or hot fermentation, carry a large amount of
H2S, owing to biogas also having substantial amounts of water vapour exist, water and the H in biogas2S acts on jointly, accelerates
The corrosion of metallic conduit, valve and effusion meter and blocking.It addition, H2SO is generated after S burning2, produce with burning
Steam in thing is combined into sulfurous acid, makes the metal surface of equipment produce corrosion, and also can cause greatly
The pollution in compression ring border, affects health.Therefore, before using biogas, it is necessary to remove H therein2S。
In sum, therefore this case gives birth to.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that one prepares cattle with cattle manure for raw material
The recycling system of bed padding, it is residual by the biogas combustion heating cattle manure of preparation after cattle manure just anaerobic fermentation
Slag obtains cattle bed padding.
The present invention solves problem and the technical scheme is that
A kind of cattle manure recycling system, includes cowshed, manure pit, homogenate successively according to cattle manure handling process
Pond, anaerobic fermentation tank, separating dry space from moist space machine and cattle manure drying chamber, described cattle manure drying chamber connects heating
