3min need to be taken only to suitable catalysis oxidation temperature 280-340 DEG C.
When " outlet temperature " show value reaches 310 DEG C on PLC control panels 18, quartz ampoule 13 times parts 4 magnetic control is opened
Pipe, when " inlet temperature " show value is at 150 DEG C, opens air-introduced machine 8, according to 7 registration of the first vortex-shedding meter, adjusts the second valve
2 apertures of door make air quantity maintain suitable size, and the organic exhaust gas of the now absorption of adsorbent layer 17 start desorbing, the height for desorbing
Concentration organic exhaust gas flow up through catalytic oxidation area, under the aerobic conditions that air-introduced machine 8 is provided, by high-performance Mn-Cu-Ce
Iolite honeycomb ceramic catalyst oxidative degradation, Mn, Cu can promote electron transmission in catalytic oxidation process, Ce have storage oxygen and
Organic exhaust gas are converted into innoxious CO by transmission oxygen function2And H2O；Purified gas temperature is high, and calorific value is big, by pipeline
Tubular heat exchanger 9 is introduced, heat is fully put aside, after the air that air-introduced machine 8 is blasted is through tubular heat exchanger 9, the air of circulation will
Heat transfer occurs significantly rising, the magnetic control tube power of scalable lower end 2 to desorption part, now " inlet temperature " display
Adjusting knob is adjusted, and " inlet temperature " is maintained 180 DEG C or so, simultaneously because catalytic oxidation stage is exothermic reaction, and is height
Concentration organic exhaust gas aoxidize, with run time increase, " outlet temperature " show also occur significantly raised, in same scalable
The 2 magnetron power regulating knobs in end, " outlet temperature " is maintained in the range of optimal temperature, by tubular heat exchanger 9 and
The setting that magnetron power regulating knob is adjusted, can largely reduce plant running energy consumption, save operating cost.
This utility model organic exhaust gas adsorption-catalytic combustion system running need to through first adsorb after catalysis oxidation, this
Matter belongs to intermittent duty, but two same device parallel connections can also meet continuous service requirement, when table apparatus are in absorption phase,
Then another is in recall oxidation stage, learns through test, after the absorption phase used time is more than catalytic oxidation stage and catalysis oxidation
Quartz ampoule cools down used time sum, so device parallel connection can accomplish continuous operation.
Although being described in detail to the specific embodiment of utility model in conjunction with accompanying drawing, should not be construed as to this
The restriction of the protection domain of patent.In the scope described by claims, those skilled in the art are without creative work
The various modifications and deformation that can make still belong to the protection domain of this patent.
