Technical field
The utility model belongs to stalk and produces biogas facility technical field, the particularly device of a kind of applied microwave and high pressure steam pretreated straw.
Background technology
China is a large agricultural country, and Model on Sown Areas of Farm ranks first in the world, according to statistics, and nearly 700,000,000 tons of current China annual stalk output.Agricultural crop straw is many is in the past used by as fuel, but along with improving constantly of our people's standard of living, and the development of rural economy and the improvement of power supply, in the last few years, peasant utilizes the burning of stalk and also reduces gradually, the quantity of residue agricultural crop straw is increasing, has reached about 400,000,000 tons every year according to estimates.The heap everywhere of a large amount of residue stalk is abandoned and is burned arbitrarily, causes topsoil, soil mineralization, fire failure, a large amount of societies, economy and the ecological problem such as block the traffic; Meanwhile, stalk, as a kind of renewable energy source, contains huge biomass energy, its recycling, to save energy, improve the ecological environment, realize society Sustainable development, have great significance.
It is that stalk, after pre-treatment, adds in methane-generating pit or tank for sewage gas and carries out anaerobically fermenting to produce biogas and organic fertilizer using agricultural crop straws such as paddy rice, corn, peanuts as raw material that stalk produces biogas.
The pre-treatment link of stalk is most important, and it is related to feed material degradation efficiency and fermentation gas rate.Traditional pre-treatment link comprises pulverizing stalk and adding microbial inoculum does stack retting etc.But the cell of stalk is very solid, cell wall structure height lignifying, xylogen wherein forms the 15%-30% of cell walls, and containing the various complex combination forms that biochemical property is very stable in these xylogen, is difficult to by general microbial decomposition.Therefore, in stalk fermentation process, lignocellulose hydrolytic process is slow, hydrolysis degree is low, thus the acidifying affected subsequently and gasification.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, the device of a kind of applied microwave and high pressure steam pretreated straw is provided, its method adopting high pressure steam and microwave irradiation to combine makes the solid lignocellulose in stalk soften, thus makes stalk in fermentation methane production process, effectively improve decomposition efficiency and the fermentation gas rate of stalk.
The utility model realizes by the following technical solutions:
A device for applied microwave and high pressure steam pretreated straw, comprises vapour generator, pre-press tank, microwave generator and Material collecting box for harvesting.
