Abstract
The present invention relates to cultivation and technical field of resource comprehensive utilization, more particularly to the ecologically raising pigs system of biomass cogeneration of heat and power, including pig room, pig raising is arranged at intervals with multiple pigsties in room, it is provided with fecal sewage collecting pit in each pigsty, sewage conduct is equipped under pig raising premises, the discharge outlet of fecal sewage collecting pit is connected to pig raising room with sewage conduct, and pig raising housing support pig is provided with heating installation, refrigerating plant, flusher, ventilation device and lighting device in room；Excrement preparing pool, detention tank, the first marsh gas fermentation pool, the second marsh gas fermentation pool, methane extraction element, methanol solution synthesizer, biogas slurry and biogas residue processing unit, methanol-water hydrogen manufacturing reformer, fuel cell and control device is respectively set outside pig raising room.The present invention generates thermal energy and electric energy using the conversion of pig raising waste object, realizes the intelligentized control method of whole system, biomass energy is made efficiently to be converted and be comprehensively utilized, and ecologically raising pigs system is formed, with wide commercial application foreground.
Description
Technical field
The present invention relates to cultivation and technical field of resource comprehensive utilization, and in particular to a kind of ecology of biomass cogeneration of heat and power
Pig raising system.
Background technology
Environmental pollution and energy shortage are global two principal themes, develop environmental improvement and the regenerative resource life of green
The technology of production is extremely urgent.According to statistics, the animal waste that China's scale animal and poultry cultivation generates every year（Excrement）It reaches
To about 3,800,000,000 tons, if being fully converted into biogas is equivalent to 1.62 hundred million tons of standard coals, and wherein only has about 15% and be equipped with biogas engineering
Processing equipment.Feces of livestock and poultry has become one of major source of agricultural non-point source pollution, and a large amount of feces of livestock and poultry is unprocessed, without authorization
Discharge, serious to polluted living environment and underground water source, waste, the pollution of foul smell are sustainable to agricultural, the health of aquaculture
Development causes grave danger.However, animal waste can both become pollution sources, it is also possible to become good biomass energy.
In the prior art, biomass producing methane has been popularized for many years.In order to efficiently use the animal dung generated in livestock and poultry cultivation
Just, some areas start with feces of livestock and poultry manufacture biogas.Biogas be organic substance under anaerobic, by the hair of microorganism
Ferment acts on and a kind of fuel gas of generation.But the method that excrement is handled during existing pig raising, existing main problem
It is：（1）Feces of livestock and poultry does not make full use of, converts, and the processing method of feces of livestock and poultry is single, without integrated treatment, processing
Efficiency is low, and occupation area of equipment is big, runs, maintenance cost height, influences large-scale promotion use；（2）Utilize feces of livestock and poultry
The biogas of preparation, which is transported and efficiently used in storage, annoyings always people.On the one hand, biogas contains hydrogen sulfide, carbon monoxide
Equal toxic gases also contain there are many miscellaneous gas, foul smell, and easy firing explodes；On the other hand, people are mainly to the utilization of biogas at present
Directly make its burn by way of obtain energy, such as cooked using biogas, heating, illumination, the using energy source of this mode
Rate is relatively low；It is generated electricity using biogas in addition, the prior art also has, but existing methane power generating system is by biogas combustion
Mode carries out heat energy power-generating, i.e., is first converted into mechanical energy from thermal energy, then be converted into electric energy, secondary conversion efficiency mistake from mechanical energy
It is low, therefore fail to be used widely.
Therefore, it develops efficient pig raising waste object processing and comprehensive utilization of resources new technology is imperative.
Invention content
For the prior art, there are above-mentioned technical problems, and the purpose of the present invention is to provide a kind of biomass cogenerations of heat and power
Ecologically raising pigs system, the pig raising system realize that biomass turns with thermal energy and the efficient of electric energy on the spot using the pig raising waste object of itself
