Using the heat accumulating type incineration method processing dust-laden VOC waste gas of device described in embodiment 1, it comprises the steps:
Containing component in the harmful gass such as toluene, dimethylbenzene, sulfur-containing compound and a large amount of dust, and operating condition in this VOC waste gas
Relatively big with flowed fluctuation, bring hot-restriking die the biggest, design exhaust-gas treatment amount 30000Nm3/h。
Heat storage 300 and oxidation Burning Room 400 are pre-purged three minutes by the freshest wind fan starting, burning are filled
Put interior residual exhaust gases to discharge；Start burner 500 firing up, be warming up to 850-950 DEG C (such as: 850 DEG C, 900 DEG C or
950 DEG C), switch into mode of operation:
The first step, waste gas is preheated to higher temperature 800-900 DEG C (such as: 800 DEG C, 850 DEG C by accumulation of heat storehouse 1
Or 900 DEG C), burn subsequently into oxidation Burning Room 400, accumulation of heat storehouse 3 330 remains untreated exhaust gas by clean gas simultaneously
Body blowback is returned oxidation Burning Room 400 and is carried out burning disposal, in oxidation Burning Room 400 ignition temperature 850 DEG C-950 DEG C (such as:
850 DEG C, 900 DEG C or 950 DEG C) between, the purifying smoke mean temperature after decomposition, at about 230 DEG C, is then passed through accumulation of heat storehouse two
320 discharge, and accumulation of heat storehouse 2 320 is heated simultaneously；Second step, waste gas is preheated to higher temperature 800-by accumulation of heat storehouse 2 320
900 DEG C, burn subsequently into oxidation Burning Room 400, accumulation of heat storehouse 1 remains the gas after untreated exhaust gas is cleaned simultaneously
Blowback is returned oxidation Burning Room 400 and is carried out burning disposal, ignition temperature (example between 850 DEG C-950 DEG C in oxidation Burning Room 400
As: 850 DEG C, 900 DEG C or 950 DEG C), the purifying smoke mean temperature after decomposition, at about 230 DEG C, is then passed through accumulation of heat storehouse three
330 discharge, and accumulation of heat storehouse 3 330 is heated simultaneously；3rd step, waste gas is preheated to higher temperature 800-by accumulation of heat storehouse 3 330
900 DEG C (such as: 800 DEG C, 850 DEG C or 900 DEG C), burns subsequently into oxidation Burning Room 400, remains and do not locate in accumulation of heat storehouse 320
Blow-back after reason waste gas is cleaned returns oxidation Burning Room 400 and carries out burning disposal, and in oxidation Burning Room 400, ignition temperature exists

When exceeding the burner stopping temperature of setting such as: when 880 DEG C, close the controlling organization 511 of regulation fuel flow rate, regulation control
The controlling organization 521 of combustion air flow, and then cut off the fuel supply of burner 500, reduce combustion air flow, until oxidation is burnt
Burn room 400 flue-gas temperature to return between normal temperature range 850 DEG C-950 DEG C (such as: 850 DEG C, 900 DEG C or 950 DEG C).Oxidation
On the right side of Burning Room 400, temperature control logic is identical with left side.
When the temperature control device 401 and 402 in oxidation Burning Room 400 detects that the average flue-gas temperature of burner hearth exceedes super
When crossing the startup waste heat boiler temperature set, open and adjusting control mechanism 611, make the overtemperature cigarette that oxidation Burning Room 400 is discharged
Air-flow is lowered the temperature through waste heat boiler 600 heat release, produces steam or hot water simultaneously, until the flue gas mean temperature of oxidation Burning Room 400
It revert between 850 DEG C-950 DEG C (such as: 850 DEG C, 900 DEG C or 950 DEG C), be then turned off the controlling organization of low-temperature flue gas flow
611。
The temperature detected when the temperature control device 311,321,331 of the heat storage in regenerator 300 exceedes setting
During the maximum allowable temperature of heat-storing material, start parking chain, cut off waste gas simultaneously and fuel feeds, open purge mode；
When the analyser 721 of chilling absorption plant 700 outlet detects the CL in purifying smoke2Or SO2、SO3Etc. harmful group
When dividing content to exceed setting value, the controlling organization 711 of regulation absorbent flow, and then regulate concentration and the flow of absorbent, directly
