Environmental degradation problem is increasingly sharpened, and environment and sustainable development is protected to become the guiding theory of energy technology development, renewable energy
The development and utilization in source is increasingly becoming focus concerned by people, and Biomass Energy Utilization technology becomes development of renewable energy in recent years
Open up one of most rapid project.
The conversion of biomass mainly uses heat chemistry and biology techniques, and biomass energy can be converted into solid-state, liquid
With the diversified energy products such as gaseous state.Biomass resource is broadly divided into animal waste and plant waste etc..
It is most of to be discarded or burned in addition to being used as feed on a small quantity for straw plant waste, it is not only unrestrained
Take resource, also polluted environment.The research of renewable energy is obtained from biomass with the methods of chemistry, can effectively utilize fibre
Dimension element and hemicellulose, to reduce conversion cost.Wherein, the crystallinity of cellulose, effective contact area, the obstruction of lignin
Biomass enzymatic hydrolysis is impacted with shroud degree of the hemicellulose to cellulose.Natural cellulosic feedstocks are directly hydrolyzed
When hydrolysis degree it is very low, it is therefore necessary to certain pretreatment is carried out to it to change structure, destroys Cellulose-lignins-half fiber
Connection between dimension element, reduces crystallinity, increases the sponginess of raw material, and enzyme hydrolysis or chemical hydrolysis is made to be easy to carry out.
For animal biolobic material, animals died of illness corpse is the infection sources of animal epidemic, if to its without processing or
Person deals with improperly, it will cause certain animal epidemic break out and it is popular, seriously affect sound development and the society of Animal husbandry production
It can public health security.Currently, the method for innocent treatment of animal carcass mainly includes incineration method, burial method, alkaline hydrolysiss and hair
Ferment method.But these single methods have shortcoming, limit the resource utilization to dead livestock and poultry.As the method for incinerating uses

Poison is blazed about by soil, underground water and insect etc., can not fundamentally eliminating pathogen, easily polluted source, no
Byproduct can be recycled, land values are influenced.Alkaline hydrolysiss processing cost is high, and effluent problem is serious, and COB/BOD is severely exceeded, fermentation
Method is limited by the factors such as weather, place, artificial, is taken long time.
Currently, the principal element for restricting biomass energy conversion is the refractory organics of biomass and the low problem of efficiency.
It is existing to mostly use mechanical crushing, the single pretreatment mode such as chemical treatment and biological treatment greatly using the biomass conversion energy；
Ultrasonic wave is the sound wave that a kind of frequency is higher than 20kHz as a kind of common physical vibration form, good directionality and penetrates energy
Power is strong.Can not only promote the activity of specific biomass degrading enzyme in preprocessing process, and its specific cavitation effect for
Groups of cells is woven with extremely strong destructiveness, and pole is conducive to the tissue breakdown of biomass and the degradation of macromolecular.
Existing ultrasonication mode carries out processing reaction to specific target using the unidirectional ultrasonic generator of single-frequency,
However ultrasonic wave has the characteristics that apparent directionality, and the wave frequency rate different for different targets can generate different processing
Effect.Since biomass class target material category is various, characteristic difference is also bigger, therefore currently with ultrasonic wave for biology
Matter carries out ultrasonication by great limitation, can not obtain satisfied effect.
