Abstract

The invention relates to a middle temperature anaerobic and dry fermentation method for wheat straw. Naturally dried wheat straws which are crushed into 1-2cm and biogas residues are added in a fermentation bottle 1 according to a weight ratio of 5-10, and fermented at a constant temperature of 30-35 DEG C. During the fermentation process, the fermentation bottle 1 is shaken duly. The gases generated in the fermentation bottle 1 go into a gas collecting bottle 2, and the water in the gas collecting bottle 2 goes into a water collecting tank through a glass pipe and a rubber pipe. Residues after fermentation can be used as fertilizers. The beneficial effects of the method are that, the method employs an anaerobic and dry fermentation method for fermentation of wheat straws, is advantaged by high gas yield, gas, gas production for a long time, low energy consumption of self and stable devices and can avoid troubles of often charging and discharging in wet fermentation. The loss of nutritional ingredients is small during the fermentation process and fermentation residues can be used as organic fertilizers with no need for dehydration.

Description

The dry fermentation process of a kind of wheat straw anaeration in normal temperature
Technical field
The present invention relates to chemical industry energy field, specifically the dry fermentation process of a kind of wheat straw anaeration in normal temperature.
Background technology
China Shi Ge large agricultural country, very abundant of agricultural straw resource, a large amount of agricultural crop straws is thrown aside or is burned, and has caused energy dissipation and environmental pollution.At present, the dry zymotechnique of most of straw anaerobic focuses on biogas output, has ignored the nutrient composition content in fermentation residue.If can take into account nutrient and the comprehensive utilization thereof of fermentation residue under the prerequisite that guarantees biogas output, not only can obtain the clean biogas energy of high-quality, and the nutrient that can utilize fermentation residue guarantees fertilizer efficiency, improves agricultural output and improvement soil, realize the co-production technology optimization of stalk marsh gas and efficient organic fertilizer, bring into play to greatest extent production potential and the environmental benefit of the dry fermentation technique of straw anaerobic, to take, the agriculture production modernization that stalk marsh gas and efficient organic fertilizer co-production technology be tie is significant.
Summary of the invention
According to above-mentioned weak point, the object of this invention is to provide the dry fermentation process of a kind of wheat straw anaeration in normal temperature.
Technical scheme of the present invention is: the dry fermentation process of a kind of wheat straw anaeration in normal temperature, it includes
1) raw material: Wheat Straw, seasoning, is crushed to 1-2cm;
2) operation steps: according to the mass ratio of Wheat Straw and natural pond slag, be that 5-10 is added in fermentation flask, 30-35 ℃ of ferment at constant temperature;
3) adopt drainage to collect gas;
Preferably: described thermostatic mode is water-bath or incubator.
Preferably: in described fermenting process, stir in good time or rock fermentation flask.
The invention has the beneficial effects as follows: the present invention adopts anaerobic dry fermentation method fermentation Wheat Straw, have gas production rate relatively high, for a long time aerogenesis, self energy consumption is low, equipment stable, can avoid wet fermentation need the trouble of frequent input and output material, the loss of fermenting process nutritive ingredient less, fermentation residue do not need to dewater and just can be used as the advantages such as organic fertilizer use.
Accompanying drawing explanation
Fig. 1 is device schematic diagram of the present invention.
Wherein, 1. fermentation flask; 2. air collector; 3. grass tube; 4. rubber catheter; 5. water leg.
Embodiment
Embodiment 1
As the device schematic diagram of Fig. 1, the ratio that is 5 according to mass ratio is by seasoning, and the Wheat Straw and the natural pond slag that are crushed to 1-2cm are added in fermentation flask 1, and 30 ℃ of ferment at constant temperature rock fermentation flask 1 in good time in fermenting process.The gas producing in fermentation flask 1 enters air collector 2, and the water in air collector 2 is entered to water leg via grass tube and rubber catheter.Residue after fermentation ends can be used as fertilizer application.
Embodiment 2
The ratio that is 10 according to mass ratio is by seasoning, and the Wheat Straw and the natural pond slag that are crushed to 1-2cm are added in fermentation flask 1, and 35 ℃ of ferment at constant temperature rock fermentation flask 1 in good time in fermenting process.The gas producing in fermentation flask 1 enters air collector 2, and the water in air collector 2 is entered to water leg via grass tube and rubber catheter.Residue after fermentation ends can be used as fertilizer application.
Embodiment 3
The ratio that is 7 according to mass ratio is by seasoning, and the Wheat Straw and the natural pond slag that are crushed to 1-2cm are added in fermentation flask 1, and 33 ℃ of ferment at constant temperature rock fermentation flask 1 in good time in fermenting process.The gas producing in fermentation flask 1 enters air collector 2, and the water in air collector 2 is entered to water leg via grass tube and rubber catheter.Residue after fermentation ends can be used as fertilizer application.
Finally explanation is, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, those of ordinary skills are to be understood that, technical scheme of the present invention is modified or is equal to replacement, and do not depart from aim and the scope of technical solution of the present invention, within it is all encompassed in claim scope of the present invention.
