Further, a high-temperature valve FY-10 is provided with the second pipeline 5.
Further, outside air inlet is provided with the 4th valve FY-11 on the 3rd pipeline 6.
In the technical scheme, tail gas caused by plant area's process units first passes around regenerative thermal oxidizer (RTO) and located
Reason, the organic principle in tail gas is oxidized into carbon dioxide and water, rich heat is emptied by high warm bypath valve.
Regenerative thermal oxidizer (Regenerative Thermal Oxidizer, abbreviation RTO) is a kind of is used in handling
The energy-saving ring protection device of light-concentration volatile organic exhaust gas.Its general principle is that waste gas is heated into more than 850 DEG C, waste gas
In organic matter oxidation reaction occurs at high temperature, the hydrocarbon in waste gas is become CO2 and H2O, be directly discharged to big
Gas.RTO devices include the ceramic filler bed heat exchanger that at least one set of heat recovery rate is up to 96%, therefore when exhaust gas concentration is higher
When, RTO equipment need to only need outside fuel preheated on startup, no longer need to use auxiliary fuel when operation.
In the present embodiment, RTO has following three states：Start pre- Warm status, running status, malfunction.
Here is the process description of each process：
(1) pre- Warm status is started
When RTO starts, main air blower starts, and fresh air valve FV-10 is opened, fresh air by 9 valves (FV-01,
FV-02, FV-03, FV-04, FV-05, FV-06, FV-07, FV-08, FV-09) cycle switching, RTO combustion chambers are purged
(security standpoint considers, prevents high concentration tail gas from remaining, and ignites during igniting), the fresh air of standby during purging.
After purging terminates, the operation of RTO combustion nozzle systems, first determine whether gas pressure is normal, it is such as abnormal, then not enough
Ignition condition, RTO will not automatic ignition, now display screen can alarm, investigate corresponding alarm item.After ignition condition meets,
RTO automatic ignitions, before this female fire light, after female fire is stable, gas electromagnetic valve action, natural gas is sprayed into combustion chamber and fired
Burn, UV flame detectors carried out fire defector every 1 second, after lighting a fire successfully, until being heated to react required temperature by combustion chamber
Degree.In this process, one direct acting of main air blower meeting, cleaned air is entered from purge lines, passes through (the FV- of 9 valves
01st, FV-02, FV-03, FV-04, FV-05, FV-06, FV-07, FV-08, FV-09) cycle switching, complete the pre- of 3 packed beds
Heat.
(2) during normal operation
Tail gas enters RTO, is first entered by No.1 ceramic filler bed heat exchanger, after the heating of ceramic filler bed heat exchanger,
Into combustion chamber oxidation heat liberation, after oxidation heat liberation terminates, portion gas is by No. two ceramic filler bed heat exchangers, by heat transfer
After No. two ceramic filler bed heat exchangers, by discharge duct, into smoke stack emission, now No. three beds are in purging state, use
Enter combustion chamber to purge the delay waste gas in packed bed and surge chamber, carry out oxidation reaction, this completes first RTO's
Work period.In second work period, No.1 ceramic filler bed heat exchanger is in purging state, and tail gas is filled out by No. two ceramics
Fill a heat exchanger to enter, after No. two ceramic filler bed heat exchangers preheat, into combustion chamber oxidation heat liberation, oxidation heat liberation terminates
Afterwards, portion gas after transferring heat to No. three ceramic filler bed heat exchangers, passes through row by No. three ceramic filler bed heat exchangers
Feed channel, into smoke stack emission, this completes second RTO work period.In the 3rd work period, No. two ceramics
Packed bed heat exchanger is in purging state, and tail gas is entered by No. three ceramic filler bed heat exchangers, changed by No. three ceramic filler beds
After hot device preheating, into combustion chamber oxidation heat liberation, after oxidation heat liberation terminates, portion gas is exchanged heat by No.1 ceramic filler bed
Device, after transferring heat to No.1 ceramic filler bed heat exchanger, by discharge duct, into smoke stack emission, this completes
Three RTO work period.So far a big cycle of RTO equipment operation is completed, RTO will continuously be run down by that analogy
Go.
