Description
Technical field
The utility model is related to a kind of environmental protection energy-saving type pig houses.
Background technology
Scale pig raising easily generates serious pollution to surrounding enviroment, and many areas have carried out a large amount of pig farm and removed work
Make, and delimit and forbidden culture zone.This ensures that pork supply and the employment of peasant bring great negative effect to China.
The pollution of swinery includes mainly the factors such as sewage, excrement, foul smell.Technology in terms of the pollution of solution pig raising in recent years has quick hair
Exhibition.These technologies have upgrading, outdoor dystopy deep-litter systems, making somebody a mere figurehead isolated hair for traditional anaerobism+aerobic aeration technology
Ferment bed technique, excrement high temperature fast fermentation in fixed etc..Although these technologies solve the problems, such as partial contamination to a certain extent,
It is to exist take up a large area, invest the defects of big, operating cost is high, and management difficulty is big, and easy climate condition influences.
For example fermentation bed is set to outside pig house to carry out excrement by current dystopy fermentation bed treatment for cow manure system, the system
Dirty fermentation process has and is extremely improved compared to for traditional contact fermentation bed.But there are more defect,
Mainly have：It takes up a large area while being easy to be influenced by outside climatic condition, in winter, especially northern area, in order to ensure
Effective fermentation temperature needs 1.5 meters or more of padding layer, is otherwise difficult the heat preservation for accomplishing bedding and padding, this just needs large-scale turn over
Rake machinery.Dystopy fermentation bed is when handling piggery waste, if the waste water entered is excessive, is easy dead bed, if into
Solid-state waste it is excessive, then fermentation bed is also easy to silt up and causes to turn over rake difficult, it is often necessary to re-replace bedding and padding, it is costly
It is high.In addition dystopy fermentation bed is a further disadvantage is that the amount of heat that fermentation generates loses in vain, and pig house needs in winter
A large amount of electric energy are expended to heat pig house.
Fermentation vat is arranged at present in the aerial isolated fermentation bed of popularization in another kind directly below hog house feces leaking floor
Carry out the processing of waste.Although the pattern avoids occupation of land problem of the dystopy fermentation bed outside pig house, and excrement need not be arranged
Dirty flusher, but the major defect of this method is that the exhaust gas of fermentation process generation and hot gas are easy to influence by screen floor for manure
The swinery of layer, especially summer, the amount of heat that aerial isolated fermentation bed generates have seriously affected the health of swinery.Machine for turning up the soil and harrowing
Tool is mounted below screen floor for manure, is easy to be influenced by the fecaluria that screen floor for manure is fallen, and often generates mechanical breakdown, and management is not also square
Just.And pig house needs that more machine for turning up the soil and harrowing are arranged, or need to add machine for turning up the soil and harrowing transfer station to move machine for turning up the soil and harrowing in a plurality of coprodaecum
Transfer, complicated for operation, investment is big.
Problem is prevented for pig house odor pollution, since the ventilation quantity on pig farm is huge, the foul smell industrially generally used is inhaled
Attached tower method is big due to investing, and the reasons such as operating cost height are still difficult in pig farm large-scale popularization application.The pig farm having been reported is smelly
Gas control prece is to install spray acid cleaning and wet curtain adsorbent equipment in fan outlet, but due to fan outlet air velocity
Height, foul smell retention time is short, and simple wet curtain lacks the prolific environment of microorganism, and odor removal efficient is not high.
