Specific embodiment
MWSI process includes solid waste storage and transportation, the stages such as burning, steam-electric power, fume treatment in furnace, in which: incinerator be by
MSW is changed into the core equipment of ashes, flue gas and heat, and bottom fire grate makes MSW move and be effective in the combustion chamber
With sufficient burning；The steam that waste heat boiler generates is for generating electricity；Some of the contaminants in flue gas are clear before being emitted into atmosphere
It removes.The MSWI process flow based on grate furnace that certain domestic enterprise introduces is as shown in Figure 1.
As shown in Figure 1, MSW is transported to discharging workshop after being collected by dedicated transport vehicle, is poured onto the solid waste pond of sealing.Pond
Interior solid waste is picked up in the feed hopper for being put into incinerator automatically by the hydraulic grab of manual control, and hydraulic feeder pushes away the interior solid waste of bucket
To grate furnace.Successively four-stage (combustion of the solid waste on fire grate is dried, lights, burns and burnt out to experience to solid waste in incinerator
Burning is slow process [16]), in which: the prewarming baking of drying stage progress MSW is to realize dehydration and heating, the heat for the MSW that burns
Thermal energy own inside heat radiation, smoke convection and the solid waste layer above incinerator is measured, the residue in afterburnt falls into water
It is pushed it into clinker pond by slag conveyer again in slag cooling bucket.In general, temperature of the incineration flue gas in burner hearth need be greater than 850 DEG C,
Residence time needs at least 2 seconds, to guarantee that will there is the MSWI process major pollutants dioxin of the characteristics such as severe toxicity, lasting to carry out
Effectively decompose.Waste heat boiler generates high steam, the power generation of pushing turbine group.It is anti-that the flue gas to be processed of boiler export enters depickling
It answers device to carry out neutralization reaction, and sour gas and absorption therein two is removed by its lime and active carbon in inlet addition
Dislike English and heavy metal (the fume treatment time is about 40 seconds), in which: flying dust enters flying dust warehouse, and flue gas enters bag filter.
Flue gas after removal flue gas particles, the progress processing such as neutralization reactant and absorption activated carbon, is divided into 3 in sack cleaner
A part, in which: tail portion flying dust, which enters after ash cellar, to be transported again to carry out harmless treatment, and part cigarette ash mixture is in a mixer
Add and reenter depickling reactor after water, tail flue gas is discharged into atmosphere through chimney by air-introduced machine, in the tail gas of discharge containing HCL,
SO2, the substances such as NOx, HF and DXN.
Currently, the control of MSWI process all uses the criterion of " 3T1E " substantially, that is, guarantee 850 degree or more of in-furnace temperature
(T), guarantee in furnace stop 2 seconds or more time (T), guarantee that solid waste mixes with air the turbulivity (T) of degree, guarantees that burning is single
Excess (E) air coefficient of position quality solid waste supply air quality and theoretical air mass ratio, control means are mainly primary
Air quantity, secondary air flow, delivery rate and fire grate speed.
In China solid waste burning field, difference burns the control system of enterprise in addition to closure is strong, different type control
Also there is larger difference between system.In addition, the external advanced autocombustion system introduced is because being difficult to adapt to China MSW spy
Property, mostly be based on experience by domain expert uses manual control mode longtime running to industry spot, is limited to operator's energy
Finiteness maintains the uninterrupted operation of MSWI process using more wheel break tour systems.As it can be seen that the Heuristics and burning of domain expert
Mechanism is lain in the magnanimity process data that DCS system stores in seconds, because of different field expert operating experience and mode
Having differences property, this also cause MSWI process operation control unstability.Therefore, it is necessary to containing Heuristics and burning
The magnanimity process data for burning mechanism is acquired in real time and off-line analysis, extracts the operation mode of fitst water domain expert and combination
Interpretable intelligent algorithm carries out the system optimizing control research of MSWI process, and then guarantees that incineration system can operate in most
Excellent economic indicator and environmental protection index equilibrium state.
Presently, there are the biggest problem be: the closure of the security requirement and DCS control system of burning power plant's operation is existing
Shape causes us to be difficult to obtain the magnanimity process data of MSWI process in real time, the modeling of newly developed MSWI process, control and excellent
The advanced algorithms such as change are also difficult to carry out online verification.Therefore, we there is an urgent need to not influence original MSWI process DCS system just
Under normal operating condition, process variable is acquired in real time using isolation method, and can to process variable collected into
Row customized type stores and utilizes real time data to carry out online verification etc. the advanced algorithms such as the modeling, control and optimization researched and developed offline
Function.
