Aforementioned and other technology contents, feature and effect of the invention are closed, in following cooperation with reference to attached drawing to embodiment
In detailed description, can clearly it present.The direction term being previously mentioned in following embodiment, such as: upper and lower, left and right, it is preceding or
Afterwards etc., it is only the direction with reference to attached drawing.Therefore, the direction term used is intended to be illustrative and not intended to limit the present invention, in addition,
In whole embodiments, identical drawing reference numeral indicates identical element.
With reference to the accompanying drawing, illustrate the specific embodiment of the present embodiment.
Fig. 1 is flow chart of the invention.Fig. 2 is schematic diagram of the invention.A kind of waste incineration and gas cleaning processing system
System.The following steps are included:
Step S1: grabbing and topples over.Overhead crane control room manipulates the rubbish in the crawl garbage pool 2 of garbage crane 3.Garbage pool 2
Volume be 6823m3, L × B × H=59m × 17.4m × 8.4m of garbage pool 2.Rubbish in garbage pool 2 is by discharging hall
Chute door 1 control discharging, rubbish is poured in grate incinerator 6.W × H=3.8m of chute door 1 × 4.5m.Garbage pool 2
Interior sewage flows into garbage leachate pond 23.The volume in garbage leachate pond 23 is 350m3, the L × B × H=20m in garbage leachate pond 23
×7m×2.5m.Sewage in garbage leachate pond 23 is promoted to decontamination water treatment station by sewage pump 5.Preferably.Garbage crane 3
For two-beam bridge grab bucket crane.
Step S2: it burns.Air needed for flue gas air preheater 4 heats burning using 6 tail flue gas heat of grate incinerator.
A fire grate left side for the primary air alternating forwards grate incinerator 6 that flue gas air preheater 4 heats and fire grate are right.Steam air heater 8
Inside it is passed through the steam taken out from steam turbine one.Steam air heater 8 is tubular heat exchanger, and fin is ellipse.And it steams
Condensed water in vapour-air preheater 8 is by going oxygen-eliminating device to take away.The auxiliary air that steam air heater 8 heats leads to respectively
After the stokehold and the furnace that enter grate incinerator 6.6 rear of auxiliary burner and grate incinerator of 6 front side of grate incinerator or quadrangle
Start-up burner light a fire.Waste heat boiler 7 above grate incinerator 6 passes through the waste heat that grate incinerator 6 generates
Recycling can produce hot water or steam connects main steam pipe to supply other workshop sections and use.The pipeline and steam-of flue gas air preheater 4
Electric butterfly valve is set on the pipeline of air preheater 8.
Hydraulic device acts on hopper baffle, dispenser, fire grate and the ash-pushing machine of grate incinerator 6.
Step S3: ash disposal.The lime-ash that the burning of grate incinerator 6 generates is fallen on belt conveyor 9 from the outlet of reserved ashes.
Lime-ash is transported to ashpit 10 by mucking machine 24 by belt conveyor 9.Landfill yard is transported to by loading machine 11.
Step S4: purification.The flue gas that the burning of grate incinerator 6 generates enters the bottom of reaction tower 12 from flue.By cigarette
The aditus laryngis of 12 ontology of road and reaction tower.In aditus laryngis, spray gun 13 is set.The lime white of atomization is sprayed by spray gun 13.With it is in flue gas and anti-
It answers.Flue gas after reaction is entering bag filter 15 after the effect of cyclone separator 14 is discharged by top by connecting bridge.Rotation
Activated carbon storehouse 20 is set on the connecting line between wind separator 14 and bag filter 15.Activity is added in activated carbon storehouse 20
Carbon.Activated carbon is passed through in bag filter 15.The material returning device 16 that dust enters 14 lower section of cyclone separator returns to reaction tower 12 and follows
Ring utilizes.Flue gas enters the bottom of reaction tower 12 from flue, by aditus laryngis (the cone junction of 12 ontology of flue and reaction tower
Point), in aditus laryngis, spray gun 13 is set, thus the lime white of atomization sprays into, since throat section product reduces, the speed of fluid increases,
Highly turbulent and air-liquid mixing is generated, the dust of entrained with is mixed among drop in gas, after fluid passes through throat, speed
It reduces, is sufficiently reacted convenient for sour gas with lime white.Gas after reaction is acted on by connecting bridge through cyclone separator 14
Enter bag filter 15 after being discharged by top, and dust then enters material returning device 16 and returns to reaction tower 12 and recycles, and passes through object
Interior circulation and powerful outer circulation (Matter Transfer number is about at 30~100 times) in reaction tower 12 are expected, so that absorbent
With SO2Mass transfer exchange between equal sour gas is strong, and the mass transport process in absorbent is strong, and solid material is in reaction tower 12
Residence time reaches 30-60 minutes, and running temperature can be down near dew point, to substantially increase the utilization rate of absorbent and take off
Sulphur rate.The moisture sprayed into neutralizing tower simultaneously evaporates at high temperature, reduces flue-gas temperature, makes the acidity in reactant and flue gas
The reaction that gas occurs is more violent, improves gas cleaning efficiency, on the other hand, flue gas can also be made to enter bag filter
When temperature control within tolerance band.In lower Ca/S ratio (Ca/S=1.1-1.5), desulfurization degree can be greater than
85%.End reaction object is discharged by 1 bottom of reaction tower and 16 top of material returning device.
Star-shaped dust-discharging valve is arranged in the exit of bag filter 15.
Step S5: curing process.The byproduct that neutralization reaction generates passes through the spiral transferring being arranged below bag filter 15
It send in the transport to embedded scraper transporter 18 of machine 17.Byproduct on embedded scraper transporter 18 is fallen into container 19.
Step S6: discharge.Purified flue gas is passed through the discharge of chimney 22 by air-introduced machine 21.
The present invention considers the factors such as economy and operation and maintenance, and the service life is long, good economy performance and does not generate secondary pollution.
Above description is explanation of the invention, is not intended to limit the invention, and limited range of the present invention is referring to right
It is required that the present invention can make any type of modification without prejudice to basic structure of the invention.
