Efficiency Large Capacity Fermentation Tank In Vessel Composting
Systems
What is In-vessel Composting?
In-vessel composting generally is the fermentation method of
organic matter that confine the composting materials within a
building container or a vessel. this fermentation method adopts
aerobic fermentation technology to decompose organic materials in
high temperature. According to the classification of composting
systems, the in-vessel composting system is belongs to the biologic
reactor system. Because the biologic reactor
usually is a vessel where the fermentation process take place.
During the aerobic fermentation process the air flows and the
temperature can be controlled greatly in this kind of composting
system. Besides, comparing with other traditional composting system
the bad weather has less influence on in-vessel composting system
and the offensive odor greatly reduced
Technological principle
The waste (livestock and poultry manure, kitchen waste, domestic
sludge, etc.), biomass (straw and sawdust, etc.) and reflux
materials are mixed evenly in a certain proportion to make the
moisture content reach 60% - 65% and then enter the aerobic
fermentation system. By adjusting the moisture, oxygen content and
temperature changes of the raw materials, the materials are fully
aerobic fermentation decomposed. The heat released in the
decomposition process can make As the temperature of sludge
increases, the maximum temperature can reach 80%. With the increase
of temperature, the moisture of materials is evaporated, and some
organic matters are decomposed, so that the volume is reduced and
the purpose of reduction is achieved. The Intelligent Composting
System controls the temperature at 55-60 ℃ (the most suitable
temperature for fermentation) through ventilation, oxygenation,
agitation and other functions to achieve the best temperature for
fermentation treatment of materials. At this temperature, it can
make a large number of pathogenic bacteria and parasites in the
material heap die. At the same time, the biological deodorization
system is used to deodorize the discharged gas to achieve harmless
treatment Goals. The materials after high temperature aerobic
fermentation can be used for soil improvement, landscaping,
landfill and covering soil, and processing into organic fertilizer
and other products..
Finite Element Analysis
Super Rotary Sludge Dryer is a newly developed sludge recycling
technology by Benenv.We have over 40 years experience on sludge
drier and carbonizer.It is the result of the painstaking efforts of
Japanese experts and Chinese professors in incineration, drying,
carbonization field. This device uses clean energy as heating &
drying energy, and direct heating method, during which no dioxins
and other toxic substances are produced.
Compared with direct sludge incineration, super rotary dryer
requires less energy with low carbon emissions, in line with
national low-carbon environmental requirements.
Advantage
Analogue simulation
The simulation of fermentation tank is carried out, and the
structural stress analysis of all parts of the tank is carried out.
When the fermenter is used for different materials, it can predict
in advance and change the corresponding structure to ensure the
stable operation of each fermenter.
Long service life
The designed service life is up to 10 years. We adopt multiple
insurance settings for the main shaft of fermentation tank to
ensure that all fermentation tanks can operate stably for a long
time.
Closed treatment system
The whole fermentation tank is sealed, and the odor generated in
the fermentation process is easy to collect.
Fermentation cycle 7-8 days
Fermentation cycle is an important factor affecting the treatment.
At present, the fermentation cycle is 7-8 days. Compared with the
traditional fermentation, the cycle is 1 / 3 of the original,
greatly improving the treatment efficiency. At present, there is
another strain under research, the cycle can be shortened to 2
days. After application, it will gradually cultivate special
strains for various materials, such as cattle manure, pig manure,
chicken manure and other specific materials.
Temperature maintaining device
When the temperature is too high or too low, our fermentation tank
will start the aeration device to maintain the temperature. What we
use is an integrated heater, not a simple resistance wire heating.
Our temperature can be set.
Accurate calculation of gas distribution axis, even mixing and
oxygen filling
Mixing uniformity is one of the important factors of fermentation
quality. We have set up a multi-layer mixing shaft inside, and each
mixing shaft has been accurately calculated, and these shafts can
bear large force without deformation. The fermenter is aerated
while stirring.
