Detailed description of the invention
This utility model is a kind of shale material drying and incineration system, is to reduce investment, operating cost, water consumption, electricity
Combustion system, heat transfer type, heat carrier type and the mummification mode of disposing technique for target, have been made Important Adjustment by consumption:
Wet for part shale material is specifically directly burned in fluid bed furnace by this utility model, and wet shale material directly burns
Burn and want simple relative to burning after mummification, but it is only with the available heat in burner hearth, normally only accounts for the 55% of calory burning
Left and right, high-temperature flue gas and steam leave burner hearth and take heat out of and be not utilized, and moisture in the shale material of general simple dehydration
Reach 75-80%, empty butt Lower heat value only 3000 kilocalorie/kilogram, this calorific value is not enough to burn whole wet shale thing in stove
Matter.Only the wet shale material of about 60% is directly burned in stove for this this utility model, remaining wet shale matter utilization
Reenter stove after stove afterbody heat mummification to burn.
Leave the high-temperature flue gas of burner hearth and heat that steam is taken out of passes to granule heat carrier, granule heat by gas-solid heat exchange
Carrier shale wet with another part material mixes in fluid bed drying device, it is achieved the mummification of shale material, part dry shale thing
Matter is burned in being also fed into incinerator, the system of total amount of heat needed for satisfied disposal.
The system that this utility model burns after being different from whole shale material (such as mud) mummification again.It is by part directly
Burn, simple and directly with furnace heat, metal heated structure in eliminating the burner hearth of complexity and in drying device
The heat-exchange system become；The stove afterbody heat being difficult by is reclaimed by it with gas-solid direct heat transfer, eliminates metal equally and is subject to
Hot side heat-exchange system；Small part wet shale material mummification in fluid bed drying device, not only reduces the volume of drying device, more may be used
So that condensation water quantity is greatly reduced, its total power consumption is significantly reduced.
Below in conjunction with embodiment, this utility model is described in detail:
Incinerator is a Circulation fluidized-bed furnace 1, and pressure is the First air cloth wind by furnace bottom of 6000-10000Pa
Plate and blast cap 2 feed, emulsion zone 3 material be particle diameter be less than 3mm, carbon containing less than 1%, initial softening temperature higher than 1100 DEG C
Grain composition.Secondary wind is fed from emulsion zone 3 upper space.Tertiary air is fed from high temperature cyclone separator 4 entrance 5.Burner hearth and height
Temperature cyclone separator 4 is combustion zone, and its temperature is at 800-900 DEG C.Low furnace temperature and sectional oxygen supply will suppress NO_x formation.
The granule that first batch of wet shale material 6 is made into individual particle weight about 1g falls into emulsion zone, and particles by heat is dried,
Fire, burning.Sending into the wet sludge quantity in stove relevant with shale substance moisture content content, moisture is the shale material of 75-80%, directly
Entering stove share is 55-65%.Limestone can be added for desulfurization in stove.
Leave in the flue gas 7 of high temperature cyclone separator containing a large amount of steam and shale material ash and desulfurization product etc.
Grain thing.They enter gas-solid direct heat exchanger 8 and solid particle 9 heat exchange as heat carrier.Gas-solid heat exchanger can be one
Individual revolving drum, solid and gas reverse flow, gas lowered the temperature (being down to 250-350 DEG C by 800-900 DEG C), and granule is heated
(being risen to 300-500 DEG C by 100 DEG C).Heat carrier granule is admitted to drying device 10.
Remaining mud 11 is admitted to drying device, and the wind-distributing pipe 16 bottom drying device feeds fluidizing gas 12, and mummification produces
Mummification steam enter condensing tower 14 together with fluidizing gas 13, steam is compressed continuation conduct being condensed into the non-noncondensing gas of water
Fluidizing gas recycles.The heat carrier granule 9 lowered the temperature and dry shale material grains 15 are respectively by drying device afterbody emulsion zone
Bottom and surface are flowed out.The heat carrier granule lowered the temperature is sent gas-solid heat exchanger back to and is reheated, and recycles；The most dry
It is interior to meet the requirement of gross heat of combustion amount that shale material sends into stove.
As a example by certain Sewage Plant mummification-CIU, its capacity is 203 ton per days, and drying device design condensation water quantity is 210
In ton/time, fluidized air blower uses two 110KW motors；According to the system that capacity is 240 ton per days of this utility model design, drying device
Design condensation water quantity is 100 tons/time, fluidized air blower uses 1 22KW motor.
