Description
Technical Field
The invention relates to compost film covering fermentation, which is particularly suitable for film covering and air exhaust in the compost fermentation process.
Background
The core mechanism is that a film-coated nano-scale microporous structure is utilized to play a certain role in preserving the temperature of the pile and reducing and controlling the overflow of odor macromolecules. Because the structure of the film is a nano-scale micropore, the film also severely restricts the evaporation and drying speed of the material water, when the temperature difference is large in winter, the surface layer of the compost body can generate a mud phenomenon, and the water is an important index of the compost quality. At present, in order to reach the fermentation dehydration effect, middle and later stages need lift the tectorial membrane corner along the heap body compartment and carry out artifical exhaust, see from actual conditions because the exhaust size masters the difficulty, and it is too big too early to exhaust, can influence the fermentation quality, and the too late undersize of exhausting has often prolonged the fermentation cycle, has increased the energy consumption, has reduced the place utilization ratio.
From the research of aerobic fermentation mechanism and process, we think that: the fermentation is the result of the metabolism of microorganisms on the mineralization and decomposition process of organic matters in the materials and the conversion and synthesis of humus, and generally, the higher the mineralization and decomposition rate of the organic matters in the materials is, the higher the metabolic synthesis rate of the humus is, the higher the fermentation quality of the compost is. In the high-temperature fermentation stage, a large amount of organic matters are decomposed by microorganisms to release a large amount of biological heat energy, and the stack body gradually goes through the temperature rising period, the high-temperature period and the temperature lowering period of the fermentation stack body from the heat accumulation and temperature rise at normal temperature. The fermented material not only carries a large amount of moisture, but also can generate some structural moisture when organic matters are decomposed, the moisture in the pile material is heated to a certain temperature and can be converted into water vapor, and the water vapor is diffused out of the pile along with aeration airflow, so that the fermentation, dehydration and drying are called. Because the pile body is covered by the membrane, the space under the membrane is extremely limited, the air vapor under the membrane is saturated quickly, the air vapor can be condensed into a liquid water membrane on the inner wall of the membrane again, the membrane covering utilizes the micropores of the membrane to permeate micromolecule gas, the membrane micropores are blocked by the condensed water on the inner wall of the membrane, the original basic air can be greatly reduced by the micropore gas amount, the total area of the normally ventilated membrane covering micropores is obviously reduced, the vapor diffusion speed is seriously blocked during the temperature rising and the high temperature of the pile body, so that the surface material of the pile body absorbs a large amount of recondensed water to increase the water content, the aeration quantity under the membrane is also forcibly reduced, the whole aerobic high-temperature fermentation process is influenced, the fermentation period is.
In the existing film covering, the film covering is to slowly exhaust by utilizing the microporous structure of the film covering, the film is covered on the surface of a stack body, the periphery of the film covering is tightly pressed to prevent hot gas from leaking, the film covering is used for enclosing and blocking the temperature of the stack body to slowly diffuse, and the total exhaust volume of the film covering micropores is reduced because the micropores are blocked by backwater formed by condensation of an inner film, so that a low-power fan is generally used for slowly ventilating and aerating (some of the film covering also has a heating function) compost. The core function of the common film coating process technology is that firstly, the stack body is subjected to heat preservation and temperature rise, and secondly, part of macromolecular odor is intercepted. Along with the high temperature period, the steam amount of the stack body is increased sharply, the water vapor saturation of the air under the film is high, and usually, only the film at the periphery of the stack body is lifted at intervals, and a method of manually discharging the discharged steam is adopted. The disadvantages are that: because the exhaust size is difficult to master, the fermentation quality is affected by too early exhaust, the fermentation period is prolonged by too late exhaust, the energy consumption is increased, and the cost is increased.
