Device 10 is presented, the pipeline of incineration flue gas advanced treating feedback device 10 is equipped with flowmeter 101 and valve 102, opens valve
102, pass through the measurable exhaust gas volumn for flowing into incineration flue gas advanced treating feedback device 10 of flowmeter 101, incineration flue gas depth
The polluted gas in flue gas can be absorbed in smoke abatement material in reason feedback device, wherein and the calcium hydroxide of foremost can absorb SO2,
Dioxin in the adsorbable flue gas of active carbon, the filter cotton for being adsorbed with sodium hydroxide solution can absorb NOX, by detecting smoke abatement object
The content of pollutant can detect the purge cases of the flue gas generated to combustion refuse in time in material, and in time to corresponding filtering
Tank is safeguarded or is improved.
As shown in fig. 7, the method that the refuse burning system is burnt away the refuse specifically includes the following steps:
Step S31: rubbish object being sent into refuse burner and is burnt, and the flue gas of refuse burner discharge is dropped through flue gas
Warm tower, which cools to 300-400 DEG C and inputted in out of stock tank again, to be handled.In this step, it burns to rubbish, and utilizes heating
Vapor generates electricity, and the flue gas of refuse burner discharge is reduced to the 300-400 DEG C for the treatment of process to meet out of stock tank.
Step S32: out of stock tank treated flue gas input smoke combustion furnace carries out second-time burning.The temperature of second-time burning is wanted
Reach 800 DEG C or more, be removal dioxin to the purpose that flue gas carries out second-time burning, and second-time burning is arranged in denitrating technique
It later, is in order to avoid the dioxin of generation secondary in denitrification process cannot be removed sufficiently.
Step S33: the flue gas that smoke combustion fire grate goes out cools to 200 DEG C or less through flue gas cool-down tower and inputs active carbon again
Tank, fiber bag precipitator are handled in deacidification tank.Flue gas cool-down can avoid secondary formation dioxin to 200 DEG C or less
Close object.
Step S34: through fiber bag precipitator, charcoal canister, deacidification tank, treated that flue gas is passed through incineration flue gas depth
Manage feedback device.Incineration flue gas advanced treating feedback device can absorb the pollutant in the flue gas for being discharged into atmosphere,
It can be used for monitoring the effect of each treatment process in front.
Step S35: in detection incineration flue gas advanced treating feedback device smoke abatement material to the adsorbance of pollutant in flue gas,
And charcoal canister, deacidification tank, out of stock tank and fiber bag precipitator are safeguarded according to testing result.If by burning cigarette
The detection of smoke abatement material in gas advanced treating feedback device, it is found that certain pollutant is exceeded, can be in time to the corresponding processing in front
Equipment is safeguarded or is improved, such as addition or more catalyst changeout, absorption material etc., or changes ignition temperature, flue-gas temperature
Etc. parameters.Further, after detecting each time, dismantling cleaning is carried out to incineration flue gas advanced treating feedback device and replaces smoke abatement
Material avoids pollution the accumulative of object, guarantees the accuracy of detection.
The utility model is described in detail above in conjunction with drawings and examples, still, the skill of technical field
Art personnel, can also be to each specific in above-described embodiment it is understood that without departing from the purpose of the present invention
Parameter changes, and forms multiple specific embodiments, is the common variation range of the utility model, no longer detailed one by one herein
It states.
