Bolted Steel Tank Used As EGSB Reactor For Biogas Production Project
What is Bolted Steel Tank?
Bolted
steel tanks are
made of individual sections including Glass-Fused-to-Steel, roof, tank ancillaries.
All the individual sections are manufactured and finished in the factory
according to strict structural specifications, with quality bends, welds and
surface processing. The bolt holes and openings will be cut by CNC laser
cutting machine automatically. Spray the glass coating on both sides of steel
panels automatically. Coating thickness is controlled within 230 microns to 450
microns. After enameling and drying, then firing steel panels in the oven at
the temperatures ranging from 850℃ -940℃, which facilitates the interfacial
fusion reactions that combine the two materials. That is what we call
Glass-Fused-to-Steel. Unlike field welded tanks, field welded tanks must be
installed on-site, often resulting in imperfect and inconsistent finished coating,
corrosion and other damage.
What is the EGSB reactor?
EGSB reactor is a successful
combination of anaerobic fluidized bed with UASB. During the primeval
fluidization in the EGSB reactor, the expansion phase ( volume expansion rate
is about 10%-30%), the velocity of the water flow is very high. It is the
speed of flow that, one and one hand accelerate the biochemical reaction by
fully mixing the substrate sludge particles with the water, on the other hand
, relieve the overloaded status in the bottom of the bed ( usually serious in
the static bed, such as UASB ) , and increase the capacity for the biologic
material especially for the toxic materials.
