Description
Technical field
The invention belongs to pulp and paper technology field, in particular to a kind of white mud lime kiln discharging device and method.
Background technique
White clay, as enterprises in pulp and paper industry alkali collection workshop generate secondary pollution solid waste, 1 ton of paper of every production or
1 ton of slurry can averagely generate 0.8-1 tons of paper white sludges, and main component is green liquor (medical fluid used in sulfate pulping) and lime is sent out
The winnofil that raw causticizing reaction (reaction of lime and carbonate ion) generates afterwards has stronger alkalinity and corrosivity.
Currently, in pulp and paper industry it is most effective and generally use and obtain insider approval processing alkali recovery white slime
Method, be to turn round limekiln using white clay to calcine white clay, by the CaCO in white clay3It is converted to CaO, is being back to use causticization work
Section.
For white clay turns round limekiln, the lime discharging method and device currently generallyd use is the stone after supercooling
Ash fully enters lime crusher, and broken rear lime enters back into lime conveyer.The tradition discharging device is substantially able to satisfy life
The requirement of production can be crushed all bulky grain lime.
But the above method and device but have two o'clock shortcoming, can not overcome always:
1) fine particle lime and dust are excessive
For normal White Mud Reclaiming Kiln in production run, the lime of generation is all largely to meet subsequent production requirement
Little particle lime, this part little particle lime is also all sent into lime crusher, in the process of running not only due to crusher
The only lime of crushing large particle can all have fragmentation to all lime for entering crusher, meet subsequent production and want
The little particle lime asked, which enters crusher also, has certain probability to be fractured into tiny particle and dust, this part small particle
Material and dust can reduce lime quality, and reduce lime conveyer transfer efficiency.
2) increase lime crusher load
Whole lime, which enter lime crusher, will increase the unnecessary load of crusher, increase abrasion and the energy of crusher
Consumption.
Therefore above-mentioned lime discharging method and device also increase loss and the energy of equipment while reducing lime quality
Consumption.
Summary of the invention
To solve the above-mentioned problems, the object of the present invention is to provide a kind of white mud lime kiln discharging devices, by lime
Increase lime sieve plate on cooler, crusher can be entered to avoid the lime for meeting subsequent production demand size and is crushed generation again
Fine particle lime and dust reduce lime crusher load and improve lime conveyer while improving lime quality
Efficiency.
It is a further object of the present invention to provide a kind of white mud lime kiln discharging methods, can not only improve lime quality, also
It can be effectively reduced the load of crusher, and be also beneficial to reduce the type selecting difficulty of subsequent delivery equipment.
To achieve the above object, the present invention takes following technical scheme:
A kind of white mud lime kiln discharging device, it includes limekiln and the lime cooler of shell and its inside；The lime
Kiln is cylindrical shape, can be rotated about the axis thereof, which is located at the limekiln periphery, and rotates with the limekiln；It should
The fan-shaped cooling space of multiple both ends opens, the interior end opening and the lime of each sector cooling space are equipped in lime cooler
The discharge port of kiln is connected to, and is equipped with lime sieve plate at the outer end opening of each sector cooling space；It is right below the lime cooler
Should the position inside lime sieve plate be equipped with little particle collection device, which connects little particle pipeline；
The position of the corresponding lime sieve plate outer end is equipped with bulky grain collection device, the bulky grain collection device bottom below the lime cooler
Portion connects bulky grain pipeline；
The little particle pipeline is equipped with the first flow divider, which is equipped with the second flow divider；First flow divider
First outlet connects lime conveyer, and the second outlet of first flow divider connects dust ram；Second flow divider
First outlet connects lime crusher, and the outlet of the lime crusher connects the lime conveyer, and the second of second flow divider
Outlet connects the dust ram.
Further, the sieve pore shape of the lime sieve plate is the square or rectangle of side length 5-100mm；The stone
Grey sieve plate screen number is 2-20X 2-20.
Further, the lime sieve plate is in tilted layout, and makes the outer end of the lime sieve plate to the lime cooler axis
The distance of line is greater than the inner end of the lime sieve plate to the distance of lime cooler central axes.
Further, the material of the lime sieve plate is identical as the material of the lime cooler.
Further, between the lime crusher and the lime conveyer, the lime crusher and described second
It is connected by the way of being flexible coupling between flow divider, between first flow divider and the lime conveyer.
A kind of white mud lime kiln discharging method, using the white mud lime kiln discharging device, it includes the following steps:
1) calcine in limekiln first passes through the fan-shaped cooling space in discharge port arrival lime cooler, so
The lime sieve plate of each fan-shaped cooling space end installation is reached afterwards；
2) little particle lime falls to little particle collection device by the sieve pore of lime sieve plate, and by little particle pipeline and
Enter lime conveyer after first flow divider；Bulky grain lime can not be by the sieve pore of lime sieve plate, from each fan-shaped cooling sky
Between end outlet be discharged, fall into bulky grain collection device, and enter lime crusher through oversized particles pipeline and the second flow divider,
Enter lime conveyer after broken；
4) underproof lime is vented directly to flying dust recycling dress by the first flow divider and the second flow divider synchronization action
It sets.
Further, the lime sieve plate, which is adopted, is connected in welded or bolted way on lime cooler, and with
Lime cooler rotated together with limekiln.
Further, the lime of variable grain size is sieved by replacing the lime sieve plate of different sieve pores.
The beneficial effects of the present invention are:
1. improving lime quality
The little particle lime that the present invention meets subsequent production requirement is no longer pass through lime crusher, keeps original granular size
Next production workshop section is sent into lime conveyer.
2. reducing lime crusher load
The present invention only has bulky grain lime and enters lime crusher, reduces lime crusher treating capacity, reduces lime
Crusher load.
3. improving lime conveys engine efficiency.
Fine particle and dust content can excessively seriously affect the conveying capacity and effect of lime conveyer in lime particle
Rate, the present invention can control fine particle and dust content in lime particle and be more advantageous to raising lime conveyer conveying effect
Rate.
4. reducing dust pollution.
The output in the main source that a large amount of dust that broken link generates is lime kiln system dust pollution, normal production
The broken bulky grain lime of needs only account for fraction ratio, therefore only crushing large particle lime can largely reduce lime and be divided into
Generation, dust pollution can be effectively reduced in the present invention.
