In use, the principal element for influencing enamel distillation still service life is enamel on stainless steel inner lining
Layer, main damage form are that burst porcelain is slightly operated since enamel distillation still is very sensitive to temperature, material and machine power
It is improper or the process is not controlled properly, enamel damage layer can be all caused, according to incompletely statistics, in enamel distillation still service life,
It destroys situation and ratio is as follows：Can body accounts for 36%, and lower liquid mouth accounts for 14%, and large flange accounts for 7.9%, and cover accounts for 6.65%,
Autoclave body deformation accounts for 3.22%, and whipping temp meter pipe accounts for 3.22%.Therefore, how to reduce the spoilage of can body is the class for being worth research
Topic.
It is found by analyzer pot body damaged part, in the existing enamel distillation still used, does not often pay attention to material
The impact force of impact force and steam, i.e., existing feeding manner is directly to be transferred to material in distillation still from feed inlet, even if distillation
It is smooth in kettle, bottom arc transition, but since material impact power is larger, it still will cause biggish impact to bottom and carry
Lotus, although this shock loading, within enamel layer tolerance range, after impacting for several times, the decline of enamel layer fatigue resistance is led
It causes strength reduction and starts cracked tendency, when intensity drops to a certain critical value, dark crackle is generated in enamel layer, is continued
After stress, the dark crackle in enamel layer develops into bright crackle, and then causes burst porcelain phenomenon；Passing through steam inlet to distillation still
When being passed through high-temperature steam in interlayer, high-temperature steam often directly causes local thermal shock to stainless steel inner lining, rapid due to temperature
It rises, stainless steel inner lining has little time Homogeneouslly-radiating toward contact and generates localized hyperthermia, and the generation of localized hyperthermia causes stainless steel inner lining
Thermal expansion coefficient everywhere is not quite similar and generates biggish thermal stress in itself, and it is bigger that this just further promotes enamel layer to generate
Stress, this stress are constantly amplified with being passed through after steam for several times, and after being more than allowable stress, enamel layer will be destroyed.
In view of this, steam baffle is all provided at steam inlet in some enamel distillation stills, to reduce the impact force of steam,
Though playing certain effect in this way, this mode quickly fills with interlayer not only bad for steam to eliminate unevenly
Heating, at the same can also material requirements to steam baffle and installation requirement it is higher, have a single function, it is inconvenient to use, still not
It can effectively solve practical problem, adaptability is poor.
In addition, existing enamel distillation still only focuses on the anti-corrosion of glass-lined coating in kettle, and do not consider stainless steel inner lining
Anti-corrosion, under high-temperature steam, stainless steel surface often occurs hydrogen attack and generates white point, and this white point provides for crackle to be split
Line source, and the generation of crackle is then the basic reason of stainless steel inner lining rupture, although stainless steel inner lining rupture odds is very
