Description
Technical field
The invention belongs to the dry materials technical field such as technical field of drying, particularly coal slime, sludge, is specially a kind of suitable
Steam rotary dry technology for the high viscous material of high humidity.
Technical background
Coal slime is the byproduct of raw coal washing processing, belongs to low heat value coal resources, has potential economic value.In recent years
Coming, coal mining mechanization degree, which improves, makes the increase of fine coal ratio, meanwhile, the increase of raw coal preparation proportion, cause floating tail-coal shape
Into slime content increase year by year.According to State Statistics Bureau's correlation estimation, annual caused about 200,000,000 tons of the slime content in the whole nation.Coal slime structure
Loosely, form is unstable, serious loss and airborne dust during accumulating and use be present, and environment makes a very bad impression.Its
Moisture content is high, viscosity is big, retentiveness is strong, is difficult to directly utilize in industry, is mainly used in people's pin.Therefore, the comprehensive utilization of coal slime
For saving resource, reducing pollution, have great importance.
Drying is to realize the important step of coal slime recycling, can digest substantial amounts of coal slime, solves environmental pollution and asks
Topic, and can Resource recovery, increase economic benefit.The main drying means of coal slime has filter press technique, aeration drying and flue gas drying method.Press filtration
Method water separation capability is limited, and aeration drying floor space is big, and is difficult to avoid that airborne dust problem, and flue gas drying method disposal ability is big, technology
Maturation, for coal slime drying mode the most frequently used at present.But there is the problem of can not be ignored in flue gas drying method：This method is with height
Wind is warmed as thermal source, inevitably to discharge a large amount of tail gas, the thermal efficiency is relatively low, and only 50% or so.In addition, flue gas drying
The problems such as local overdrying, vent gas treatment are difficult, occupation area of equipment is big also be present in method.For the coal slime of high volatile, it is also possible to
Cause coal combustion, possess certain potentially danger.Therefore, take one thing with another, it is necessary to exploitation more energy-conservation, safety,
The coal slime dry technology of environmental protection.
Low-temperature steam drying technology is a kind of indirect heat exchange technology by the use of low-pressure saturated steam as thermal source.It dries temperature
Spend it is low, without dust explosion risk, for tail gas only as moisture is taken, discharge capacity is small, the thermal efficiency up to more than 70%, have safety and stability,
The features such as energy-conserving and environment-protective.Because the afterheat steam of the enterprises such as the technology recoverable power plant is as thermal source, the thermal efficiency is set to enter one
Step improves, and coal washery is adjoined with power plant more, possesses the natural endowment of UTILIZATION OF VESIDUAL HEAT IN, and therefore, the technology dries field in coal slime
With vast potential for future development.
But because coal slime viscosity is high, retentiveness is strong, the problems such as viscous wall, putty are also easy to produce in drying machine, cause drying
Machine is difficult to normal operation.Therefore, there is certain difficulty in application of the steam drying technology in coal slime drying, only exist in emerging rank
Section.A kind of present invention seek to address that problem, there is provided steam rotary dry technology suitable for high humidity high-viscosity material.
Prior art one：One kind of Shandong Tianyuan energy-saving environment protection engineering Co., Ltd application uses steam waste heat to be changed for thermal source
The roller drying device of the adjustable charging character of heat, number of patent application 201310211940.0.Its main technical content：The technology
Propose a kind of roller drying of the adjustable charging character for the form being combined using steam indirect heat exchange and hot blast direct heat transfer
Device.By groups such as feed arrangement, rotary roller dryer, drawing mechanism, waste-heat recovery device and automatically controlled and automatons
Into.Using steam as main heating source, the high temperature air after waste heat recovery is sent into by feed arrangement and turned round as secondary heat source, material
Roller drier, by completing primary drying after drying machine.Dried material distributes through drawing mechanism, and a part is as dry production
Product, a part return to feed end.The dry material of return is mixed with undried wet stock and broken up, and wet stock adjustment is turned into and is more easy to
In scattered form.Then, drying machine then by feed arrangement is sent into, completes redrying.So constantly circulation.
The main body of the technology is rotary roller dryer using steam as main heating source, indirect heat exchange, suitable for sticky
The drying of material, also well adapting to property is dried to coal slime.But the present situation that current coal slime is produced on a large scale, to equipment
Disposal ability there is very high requirement.The technology dry material carries out redrying after returning to feed end blending, inevitably
The actual treatment ability of equipment is reduced, meanwhile, the system support equipment is more, complex operation, and operating cost and maintenance cost are equal
It is higher.
Prior art two：A kind of sludge steam of Tianhua Institute of Chemical Machinery ＆ Automation Co., Ltd.'s application returns
Turn drying machine drying means, number of patent application 201410341724.2.Its main technical content：The technology proposes one kind with low pressure
Saturated vapor carries out the drying means of contact drying to sludge with steam rotary dryer, mainly fed by spiral as thermal source
Machine, steam rotary dryer, hot-water cylinder, blocking valve, spray scrubber, condenser, air-introduced machine, circulating pump, heat-exchanger pump etc. form.
Heat-exchanging tube bundle is provided with steam rotary dryer, sludge is sent into drying machine by feed screw, 0.2~1.0MPa (G) saturation
Steam enters tube side, and sludge is exchanged heat in cylinder with the steam in heat-exchanging tube bundle, heat temperature raising dehydration, reaches dry
Purpose.Dried sludge is discharged by blocking valve, and the condensed condensed water of steam is after hot-water cylinder is collected by hot water pumped back electricity
Factory.Dry tail gas be containing humid air, after drawing drying machine by air-introduced machine, the purifying and dedusting first in spray scrubber, Ran Houjin
Enter condenser, with cooling water indirect heat exchange, make to take the water vapor condensation in moisture, reclaim condensed water, the tail gas after cooling is sent into
Aftertreatment systems, the cooling water storage of recovery are stand-by.
The technology can use steam rotary dryer to dry sludge, also there is certain adaptability to coal slime.But for coal
The characteristics of mud high viscosity, the technology lack corresponding counter-measure, for common steam rotary dryer, for coal slime
When drying, it is difficult to the technical problem such as the presence putty that avoids, viscous wall, and content of ashes is higher in coal slime, and it is more serious to glue wall problem.
The content of the invention
For materials such as existing coal slime, sludge, existing putty, viscous wall, disposal ability are low, supporting in the drying process
