Abstract
The invention discloses a wet storage method for crop straw. The method comprises the steps of straw treatment and storage. The method comprises the following specific steps of: firstly, harvesting straw, grinding in time, wherein the length of ground straw is controlled to be between 3 centimeters and 6 centimeters; secondly, putting the ground straw into a storage cabin within 4-6 hours, and rolling in time, wherein the bulk density is controlled to be between 0.3 T/m<3> and 0.5 T/m<3>, straw is ensured to be in a facultative state, and the saccharification degree and speed of a material are lowered; and draining in the storage cabin by using a drainage system; and spraying a low-concentration aseptic bacterial liquid onto the straw for sterilizing. In the technical scheme, the storage method is suitable for the using characteristics of China. By adopting the method, the wet storage time of crop straw is over one year, the energy loss in an entire process is not more than 10 percent, and the scale raw material supply of an enterprise can be met basically.
Description
Technical field
The invention belongs to agro-ecology matter field of energy utilization, relate in particular to the wet method that stores of a kind of crops straw.
Background technology
China agro-ecology mass-energy source utilizes very fast development in recent years, technology such as gasifying stalk, biomass molding fuel has all entered the through engineering approaches stage, the straw power generation technology also has the dozens of point in experiment, other liquid fuel technologies are also carrying out the stage experiment, these energy utilization technologies and other bio-based product processing technique have all run into same problem in force, " stable, the whole year of stalk are supplied with continuously ", just the storing technology problem of results back stalk.
Distribute though crops straw is abundant disperse, bulk density is low, it is higher to contain moisture after the results, mostly surpasses 40%, common open-air method of piling can cause environmental pollution, energy to prolong in time to reduce by 5% speed the moon to decompose and lose, also easily cause and go mouldy.This utilizes stalk on a large scale with commercial running is unconformable.
The wet storage of stalk is global problem.The U.S., European Union all list the wet storage of stalk in living beings and utilize technology path figure; And by governmental investment, experimentize, although a large amount of experiments has been done by states such as the U.S., European Union, have in addition store more than ten thousand tons, also run into mouldy rot often, cause and store failure.China starts late as the research of the stalk scale storage of using energy source, and the influence of systematic constraint and the low factor of level of farming mechanization, has increased the storage difficulty.
Summary of the invention
Technical problem to be solved by this invention provides a kind of storage time and can reach more than 1 year, and the overall process energy loss is not more than 10%, can satisfy the wet storage method of crops straw of enterprise scale raw material supply basically.
Adopt following scheme in order to solve above technical problem: the wet method that stores of a kind of crops straw, comprise the processing of stalk and the storage after the processing, at first, in time pulverize stalk results back, and the stalk length of pulverizing is controlled at 3-6cm; Then, in 4-6 hour, enter storage warehouse and roll extrusion in time; Bulk density is controlled at 0.3-0.5T/M
3, guarantee that stalk is in double oxygen condition, the saccharification degree and the speed of the material that slows down, storage warehouse adopts the draining of infiltration system; On stalk, spray the sterilization of the anticorrosion bacterium liquid of low concentration.
The ground of described storage warehouse is provided with drainage and down oozes the hole, and ground flare 8～12 is spent; With the dew of deploying troops on garrison duty of the black plastics more than 2 meters, black Polypropylence Sheet is provided with weep hole all around; Fill the back and bind, and, on the black Polypropylence Sheet in top, Judas-hole are set with the stalk compacting after pulverizing with black Polypropylence Sheet.
The anticorrosion bacterium liquid of described low concentration is formic acid, formaldehyde, propionic acid or lactic acid bacteria.
The anticorrosion bacterium liquid of described low concentration is formic acid and formaldehyde mixed liquor or formic acid and propionic acid mixed liquor.
The consumption that the anticorrosion bacterium liquid of described low concentration and crushing straw per ton spray be following any one:
