How to choose and design the mixer is very important to the harmless treatment and resourceization of the aaerobic fermenter and agitator in the manufacture and use of the anaerobic fermenter and the mixer: Many fermenters and agitator structures are still on the basis of relying on empirical, and there are many unreasonable phenomena in the design, the applicability, short life, poor durability, and the design of the fermenter, which is easy to cause the fermentation effect.
Waste, loss; current large anaerobic tank, due to unreasonable installation position, mixer mounting parameters are not standardized, agitation effect, easy to cause dead bed, resulting in sludge, expansion, and anaerobic bacteria Rapid growth, the effect of nanopasis is not ideal, and the biogas is rare., the fermenter design is not standardized, the strength and stiffness are not guaranteed, and the safety accidents such as tank breakage, even collapse are extremely susceptible.
The lower the COD concentration of the treated sewage, the lower the methane productivity of the unit organic matter; the temperature affects the product generation rate and yield, suitable temperature Under conditions, the faster the fermentation reaction, the more obvious the effect of the microorganism, the higher the gas production efficiency, but the temperature of the high temperature will inhibit the growth of microbial growth, the temperature of the fermenter is 35 & Plusmn; suitable; good corrosion resistance of the fermenter , Intensity and stiffness need to meet the standard, carry out the necessary opening reinforcement; according to the actual demand of the large and medium-sized biogas technical specifications and projects, the fermenter design is 1 ~ 2MPa, the design volume is 1000m3, the China fermentation tank factory fermenter high diameter ratio is 0.
The fermenter system mainly includes a tank, a mixer, a snake tube heat exchanger, a reflux mixing system, an insulation layer, a human hole, a colored steel plate, a positive and negative pressure protector, etc. The fermentor is often built in the suburbs of the city. The high or too low pH will affect the speed of the fermentation, the pH is 6. The huge fermenter of the scale is often more susceptible to seismic load, wind storage, etc
