Abstract
The utility model relates to a device for removing lignin by pretreating biomasses through enzymolysis, and particularly relates to a device for removing lignin in straw by pretreating before fermenting the straw. The device is internally provided with a partitioning plate; one side of the partitioning plate is provided with a pretreating device, wherein the upper part of the pretreating device is provided with a feeding hole, the lower part of the feeding hole is provided with an enzymolysis stopping device, and the lower part of the pretreating device is provided with a discharging hole; the other side of the partitioning plate is provided with a fermenting device; the fermenting device is internally provided with a stirring device; a rotating shaft of the stirring device is connected with the upper end of the device; the lower end of the rotating shaft is provided with stirring paddles; an isolation plate is arranged in the middle of a reactor; the rotating shaft of the stirring device penetrates through the isolation plate. During fermenting, after the lignin in the straw is removed by the enzymolysis stopping device, the straw is added into the pretreating device and pretreated. The fermenting substances can be stirred by the stirring device and isolated by the isolation plate and left on the lower part, thus the incomplete fermentation of the straw can be prevented, and the fermentation rate can be improved.
Description
Technical field
The utility model relates to a kind of enzymolysis preprocessing biomass and removes the xylogen device, especially stalk is carried out enzymolysis and removes the device that ferments again after the lignin pre-treatment.
Background technology
Along with the development of agriculture production, China is since the eighties in 20th century, and grain yield significantly improves, and stalk quantity also increases, because burning straw, makes the concentration of flue dust in the air, particulate matter and other pollutents sharply increase, and Air quality descends rapidly.Fermentation reactor is a kind of device of fermentation gas commonly used, stalk can be carried out producing methane through anaerobic fermentation, but the structure on stalk surface has reduced the fermentation efficiency of stalk, has limited the fermentation of stalk.
Summary of the invention
In order to solve the problem of stalk surface tissue restriction stalk fermentation rate, the utility model provides the enzymolysis preprocessing biomass to remove the xylogen device, this device ferments after stalk is removed the lignin pre-treatment again, has improved the fermentation rate of stalk simply and easily.
The technical scheme that its technical problem that solves the utility model adopts is: device inside has dividing plate, dividing plate one side is pretreatment unit, the top of pretreatment unit installs opening for feed additional, the opening for feed bottom installs the enzymolysis device additional, install discharge gate additional in the pretreatment unit bottom, opposite side is fermentation unit, its inside installs whipping appts additional, the rotating shaft of whipping appts is connected with the device upper end, and stirring rake is installed in the lower end of rotating shaft, and division board is installed at the reactor middle part, has small-sized hole on the division board, division board is passed in the rotating shaft of whipping appts, and the shell upper end has gas recovery pipe, and nutritive medium adds pipe.When fermenting, stalk is gone into pretreatment unit through removing the enzymolysis device except delignification is laggard, and carries out pre-treatment interior, whipping appts can stir fermented product, fermented product is isolated in the bottom by division board, and this just prevents the incomplete situation of stalk fermentation, has improved the stalk fermentation rate.
The beneficial effects of the utility model are that enzymolysis is removed the lignin device stalk is carried out fermenting after the pre-treatment again, has improved the stalk fermentation rate.
