Dangerous factor.
(5) the material outer diameter of internal layer cylinder and outer layer barrel before processing is more than and is sized, and internal diameter, which is less than, to be sized,
In this way repeatedly to process, the length of internal layer cylinder is more than the length of outer layer barrel, and the internal layer cylinder upper surface point side of being welded with
Just the fixed block of internal layer cylinder is moved, internal layer cylinder deforms when thus being avoided that clamping and hot jacket, internal layer cylinder and outer layer barrel
Length of material increases, and avoids hot jacket rear end Light deformation and hot jacket not fine and close.
(6) tenon structure mutually agreed with is provided on the grommet being oppositely arranged in the present invention, in this way in past reactor
When reaction gas is poured into inner housing, the dislocation of grommet will not be caused due to internal pressure.
(7) it first treats that welding zone and second treats the setting of welding zone shape and position in the present invention, can increase and treat in welding zone
Scolding tin and the contact area for needing connecting component can effectively increase the firmness of welding in this way.
(8) technological parameters such as medium, temperature and pressure that lining reactor of the present invention is used according to reactor, pass through calculating
Analysis and verification experimental verification optimize reactor shell and thin-walled lining structure, comprehensive using Precision Machining and hot cover process technology, make
Thin-walled lining is bonded with outer housing precision.One side thin-walled lining uses corrosion-resistant material or high pure metal material, with full
Sufficient reaction medium is to reactor wall material performance requirement；Meanwhile the innovation of lining inner casing is using Precision Machining and hot cover process skill
Art carries out Stress Check by calculating not equality of temperature base of a fruit layer materials swell increment and the lower liner shell of interfacial stress effect, protects
It has demonstrate,proved lining inner casing not crack in high temperature and pressure, the Problem of Failure such as fold, bulge, the such harshness of solution do not use under low-temperature negative-pressure
Lining reactor failure problem under environment.
