Specific embodiment
Embodiment 1
It mixes burning and selects unit boiler experimental design Coal-fired capacity are as follows: single furnace 60t/h.
The manufactory of coal-powder boiler is east boiler industrial corporation；Model DG450/9.81-9.
Printing and dyeing sludge is carried out dehydrating to moisture content and is less than or equal to 60%；Obtain spare printing and dyeing sludge；
When the moisture content of spare printing and dyeing sludge is 40.1-60%；By spare printing and dyeing sludge: (spare printing and dyeing sludge+coal
Powder)≤0.1；Configure spare printing and dyeing sludge and coal dust；
When the moisture content of spare printing and dyeing sludge is less than or equal to 40%；By spare printing and dyeing sludge: (spare printing and dyeing sludge+coal
Powder)≤0.15；Configure spare printing and dyeing sludge and coal dust；
After mixing, powder processed will be dried with the spare printing and dyeing sludge and coal dust taken；Obtain fuel；
Fuel feeding coal-powder boiler is burnt；Collect the dust in flue gas.
Fineness R90=16~19% of fuel.
It mixes and combusts coal and sludge quality is shown in Table shown in 1 and 2, then according to mixing burning condition, fuel element content and its corresponding
Fuel quantity, it is as shown in table 1 below that the dirty increment of fuel burning various elements production is mixed in reckoning:
Table 1 mixes burning condition and element increment list (unit: kg/h)
Note: increment is the various increments mixed burning condition and mix constituent content under the conditions of burning with nothing in upper table, and ": ", which represents, is reduced.
Table -2 mixes each Theory of Components analytical table (unit: kg/h) in burning front and back
From table 1 it follows that its C, H, O content substantially reduce in the case of mixing burning, S, N and ash content are dramatically increased, a huge sum of money
It is not of uniform size to belong to increment.
Wherein S element increases between 6.8%~38.2%, and N element increases between 2.3%~17.8%, and ash content increases by 0.9
~11.7%, heavy metal index increment is between -3.7%~56.6%, and wherein Ni increment is negative, and increment is maximum for Zn member
Element, it is higher that entire experimental data shows that the biggish sludge smoke test achievement data of the lower mixed-fuel burning proportion of moisture content is higher than moisture content
The trend of the lesser sludge of mixed-fuel burning proportion is substantially proportional to the absolute additive amount of sludge.By experiment it can be seen that 40% with
The printing and dyeing sludge of 60% moisture content respectively with coal with 15% and 10% ratio mix burning disposition be it is feasible, not will cause secondary dirt
Dye.Under the conditions of mixfiring test, comparison becomes printing and dyeing sludge without burning situation, sulfur dioxide and discharged nitrous oxides are mixed when sludge mixes burning
Change smaller, the pollutants such as individual heavy metals and dioxin concentration slightly raising after combustion, but concentration changes very little, into flue excessively
And after relying on existing Pollution treatment installation, smoke emissioning pollution concentration is suitable with without burning situation is mixed, and 60% and 40% is aqueous
The sludge fuel mixing ratio of rate can reach relevant criterion requirement, mix flue gas Conventional pollution and the huge sum of money for burning and finally draining into atmosphere
It is unobvious to belong to concentration variation, qualified discharge can be achieved, be better than 2000 standard level of European Union.Wherein: during mixing burning, heavy metal
Increased in flue entrance according to the sludge quantity of incorporation and be slightly changed, fuel mid-boiling point lower volatile As, Hg, Cd, Zn exist
Volatile quantity is maximum in combustion process, most of to be gasified in combustion, but is partially converted into after flue is cooling solid
State is collected in inside flyash, only fraction enters flue gas, so end together after flue gas purification device with flue dust
Content is very low.Cr, Cu, Ni and Pb are because boiling point is higher, the amount very little to gasify after burning, most of to enter cigarette with flue gas with solid-state
Road is largely trapped in flue gas purification device, so concentration of emission is also very low.Wherein because in sludge Ni, Pb content be lower than
Content in fire coal, Ni the and Pb content in sludge fuel exhaust gases after combustion are slightly below burned coal-fired, and sludge incorporation is bigger
Content is lower in exhaust gases after combustion, and content of other heavy metals in sludge is higher than content in fire coal, so burning sludge fuel
Heavy metal slightly above burns fire coal in exhaust gas afterwards, but compared to without in the case of mixing burning, flue gas heavy metal content has no significant change.
Under the steam power plant's unit nominal situation condition and flue-gas cleaning devices normal operation that mixfiring test is relied on,
And under the conditions of mixfiring test, the generation of dioxin and total solid content and fuel mixing ratio relationship are unobvious, with burning mixed mud moisture content
Related, the higher intramolecular moisture content that may cause of burning mixed mud moisture content is more, is unfavorable for completely burned, and dioxin concentration slightly rises
Height, but largely depend on relying on the working condition of engineering, exit concentration is largely associated with unit and flue gas
Purification facility operation conditions；The steam power plant's one phase unit working condition and flue-gas cleaning devices relied in mixfiring test is normally transported
In row situation, dioxin is generated when sludge mixes burning and exit concentration is lower, better than the discharge standard of European Union 2000, and is much better than wide
East saves provincial standard (2000/76/EC).
