Description
Technical field：
This method belongs to field of environment protection, is the exhaust-gas treatment with regard to petrochemical enterprise sewage farm
Device.
Background technology:
Petrochemical enterprise sewage farm adjusts homogenizing tank in sewage disposal process, oil interceptor, air supporting set
Apply and all produce substantial amounts of waste gas, the exhausted air quantity that biochemical treatment facility is discharged is bigger, but concentration is relatively low.Foul smell master
Will be by groups such as air, hydro carbons, hydrogen sulfide, vapor, due to the foul smell impact atmospheric environment of discharge, impact
Operator's is healthy, and these waste gas are required for carrying out deodorizing process.Exhaust air deodorization processes and adopts at present
Method be Production by Catalytic Combustion Process, biological odor removal method, but, all there are some problems in these methods：Catalysis combustion
Burning method, investment is big, high energy consumption, operating cost are high；In waste gas, the content of hydrocarbon reaches and can produce during finite concentration
, there is certain potential safety hazard in detonation；The waste gas that burning produces directly discharges, and there is certain abnormal smells from the patient；Only
Can process and adjust homogenizing tank, oil interceptor, the waste gas of air supporting facility generation.Biological odor removal method, investment is also compared
Greatly；The pollutant that some can not dissolve in water can not remove；Disposed of in its entirety less effective；It is only used for processing life
Change the waste gas that pond is discharged.
So, from the point of view of technology trends and energy-saving and emission-reduction, the present invention relies on existing waste to burn
Burn facility, petrochemical enterprise sewage farm waste gas is utilized and processes as the combustion-supporting gas of burning facility,
Finally realize high efficiency, the low-cost processes of petrochemical enterprise sewage sewage farm waste gas, be to have to burn
Burn a kind of new method of the petrochemical enterprise exhaust-gas treatment of facility.
Burning facility is a kind of technology of utilization high temperature burning handling waste.Waste crosses high temperature in incinerator back warp
Heating burning, can obtain innoxious to greatest extent and minimizing process.In incinerator, hot environment is by firing
The heat that material is produced with waste combustion maintains.After incinerator, the air mainly containing is helped waste gas by conduct
Combustion gas body utilizes, and can discharge certain heat for maintaining the temperature in incinerator after the hydrocarbon fuel containing,
Thus reducing the usage amount of fuel, reduce operating cost.Other materials in waste gas are reacted in high temperature environments
Degraded, reaches harmless treatment.
The tail gas that incinerator is discharged contains amount of heat, contains the pollutant such as flue dust and nitrogen oxides simultaneously.Tail
Heat in gas can be utilized by waste heat boiler.By the flue dust in bag dust arrester installation removal tail gas, ammonia
Spray system go in denitrification, fresh slaked lime and the measure such as corrosivity acid gas after, tail gas is finally up to standard
Discharge.Process in conjunction with sludge incineration, how the two technology to be carried out merging, reduce investment and operating cost,
The thorough deodorization of waste gas, becomes petrochemical enterprise sewage farm exhaust air deodorization problem demanding prompt solution.
Content of the invention
For investing in prior art processing procedure, big, operating cost is high, the halfway problem for the treatment of effect,
The present invention provides a kind of wastewater treatment field waste gas processing method, reduces investment and operating cost, improves treatment effect.
A kind of wastewater treatment field waste gas processing method, the waste gas producing in the sewage disposal process of sewage farm is passed through
Gas mixing tank delivered to by waste gas collection device and air-introduced machine, and in gas mixing tank, waste gas and air mixing are laggard
Enter incinerator, gas mixing pot bottom excludes lime set, the high-temperature flue gas that incinerator is discharged pass through waste heat boiler,
Desulphurization denitration, dedusting, entrance chimney discharge.
A kind of described wastewater treatment field waste gas processing method it is characterised in that：Warp before waste gas enters gas mixing tank
Cross a spark arrester, spark arrester is arranged between air-introduced machine and gas blending tank.
A kind of described wastewater treatment field waste gas processing method it is characterised in that：Pressure in gas mixing tank be -200～
-500mmH2O, preferably -250～-350mmH2O.
A kind of described wastewater treatment field waste gas processing method it is characterised in that：Described incinerator is by a combustion room and two
Combustion room is composed in series, and the ignition temperature of a combustion room is 850～950 DEG C, and secondary combustion chamber ignition temperature is more than
1100℃.
A kind of described wastewater treatment field waste gas processing method it is characterised in that：The high-temperature flue gas that incinerator 5 is discharged enter
Enter waste heat boiler produce steam, flue-gas temperature be reduced to 500～600 DEG C enter desulphurization denitration towers in carry out desulfurization take off
Nitre, flue gas enters chilling tower and carries out water-cooled, reduces the temperature to 200 DEG C, and deacidification dedusting is discharged through chimney.
Compared with prior art, a kind of beneficial effect of wastewater treatment field of present invention waste gas processing method is：
1st, small investment
On the basis of existing waste gas collection device, air-introduced machine, spark arrester and sludge incineration device, increase gas
Body blending tank, replaces catalytic combustion system and the biological deodorizing device of prior art.
2nd, operating cost is low
(1) gas sampling that prior art waste gas collection device is collected is to catalytic combustion system or biological deodorizing dress
Put, the gas sampling that the technology of the present invention waste gas collection device is collected is to gas mixing tank；Prior art mud burns
Burn the fire-retardant air of device and come from air, the fire-retardant air of the technology of the present invention sludge incineration device comes from gas to be mixed
Close tank.Waste gas collection device air-introduced machine, sludge incineration device air-introduced machine prior art equally configure, and do not increase
Plus operating cost.
(2) all save the energy consumption of catalysis burning and the energy consumption of biological deodorizing device, significantly reduce fortune
Row expense.
(3) all save the expense of catalysis burning, the checking maintenance expense of biological deodorizing device and more catalyst changeout
With significantly reducing operating cost.
(4) produce heat in the organic pollution combustion process in waste gas, partly instead of combustion-supporting fuel,
Part reduces the operating cost of incinerator.
(5) heat of the generation that catalysis burning produces directly discharges, and the heat that incinerator burning produces passes through
Waste heat boiler recovered steam.
3rd, treatment effect is more preferable
(1) the untreated direct discharge of tail gas that catalysis burning produces, after incinerator burning, tail gas passes through
Strict process, processes more thorough.
(2) biological deodorizing can not dissolve in the pollutant of water and cannot process, 1100 DEG C of incinerator ignition temperature,
Pollutant are all decomposed, and process more thorough.
4th, operation is safer
In the waste gas that regulation homogenizing tank, oil interceptor, air supporting facility are collected, the content of hydrocarbon is higher, under normal circumstances
It is not up to explosion limit, when concentration is especially high, reaches explosion limit, produce detonation；Incinerator is due to mixed
Enter the waste gas of biochemical treatment facility discharge, be mixed into air, the concentration of hydrocarbon reduces a lot, will not produce quick-fried simultaneously
Combustion is dangerous.
5th, adaptability is higher, it is simpler to manage
Incinerator can replace catalysis burning, biological deodorizing device to process whole waste gas, eliminates catalysis combustion
Burning, the management workload of biological deodorizing device.
