Description
Technical field
The present invention relates to a kind of steam-cured processing unit, more particularly to a kind of steam curing device handled for lignite upgrading;Category
In pressure vessel.
Background technology
Steam-cured kettle is also known as still kettle, is a kind of large pressurized vessel, is commonly horizontal type structure;Built available for air entrained concrete
Block, concrete tubular pile, Dinas brickes, coal-dust brick, calcium silicate board with microporous, New Type Light-weight Wall Material, insulation asbestos board, high intensity stone
The construction materials such as cream carry out steam press maintenance, and purposes is quite varied.
Lignite water content and oxygen content are high, calorific value is low, easy spontaneous combustion and weathering, store more difficult;In order to effectively using brown
Coal, it usually needs it is dried upgrading processing.However, (adsorbing water in water in lignite and being stored in lignite texture and capillary
Capillary water in pipe) handled through drying and upgrading and after being removed, inside lignite and surface can leave substantial amounts of crack and texture, more
Easy oxidation by air heating and spontaneous combustion;Need to fill lignite crack and texture using nitrogen, to suppress its oxidation.
At present, upgrading processing lignite generally is dried using horizontal steam-cured kettle;Bothered in the presence of charging and draw operation,
Efficiency is low, floor space is big, capacity utilization is low, be not provided with nitrogen supplementary device, the easy corrosion and damage of kettle body body, waste heat
The defect such as utilization rate is low, energy consumption is high.Concrete analysis is as follows:
1) lignite be particulate species loose unpacked material, therefore typically will by container load could be fed, draw operation;
Time-consuming, efficiency is low.
2) loaded using container and be difficult to fill up in space in kettle, capacity utilization is low.
3) without nitrogen supplementary device, it is impossible to inject nitrogen filling lignite crack and texture into kettle.
4) the easy corrosion and damage because of electrochemical reaction of kettle body body:In order to avoid boiler corrosion and fouling is avoided, stove
Water is usually pH10 or so.When being passed through in weakly alkaline steam (equivalent to electrolyte) in kettle, between kettle body body and lignite
Be easy to turn on and form two electrodes (equivalent to large-scale galvanic cell);In addition the factor such as temperature in the kettle, pressure is present, and accelerates original
Cell oxidation reduction reaction, so as to cause, to kettle body body fast erosion, to directly affect steam-cured kettle service life.
5) generally all it is directly to discharge the high-temperature steam in kettle when needing release to cool after the completion of steam-cured operation, it is remaining
Heat utilization is insufficient.
The content of the invention
For drawbacks described above present in prior art, the present invention is intended to provide a kind of capacity utilization is high, input and output material behaviour
Make convenience, service life length, save the energy, the steam-cured processing system of lignite of lignite spontaneous combustion can be avoided.
To achieve these goals, the present invention uses following technical scheme:It includes steam-cured kettle;The steam-cured kettle is two
It is individual, each steam-cured kettle by can-like structure and vertically fixed kettle body body, be fixed on the kettle body body upper port top cover, with should
Passage that kettle body body lower port is docked and connected and is in tilted layout, it is fixed on the bottom of the passage port of export, positioned at kettle body
In body and by the equally distributed many epimere steam pipes of vertical mode and Duo Gen hypomeres steam pipe and many pumping drain pipes
Constitute;One end of each epimere steam pipe in two steam-cured kettles respectively with first distribution cylinder connect, the other end respectively by with
The external pipe correspondence of valve is connected, one end of each hypomere steam pipe in two steam-cured kettles connects with the second distribution cylinder respectively,
The other end is connected by the other valvular external pipe correspondence of band respectively, each pumping drain pipe one end in two steam-cured kettles point
Do not connected with moisture separator;Two passages are connected with nitrogen gas generating device respectively.
The moisture separator by be connected with pumping drain pipe moisture separator, by the moisture separator and soft water pond
The water pump of connection is constituted;Have discharger in passage, the discharger by be horizontally arranged in passage two rotating shafts, be fixed on
Polylith blade in each rotating shaft is constituted;The lower semisection of kettle body body has and its internal air bubble connector connected;In nitrogen hair
The first magnetic valve and blowoff valve are mounted on connecting pipeline between generating apparatus and each passage, in the first distribution cylinder and respectively
It is mounted on the connecting pipeline of epimere steam pipe and on connecting pipeline of the second distribution cylinder with each hypomere steam pipe another
The first outer magnetic valve;Multiple sensors are distributed with kettle body body;Have vertically fixed electrode in kettle body body, each electrode with
The positive pole electrical connection of dc source, the inwall of each kettle body body is electrically connected with the negative pole of the dc source.
Compared with the prior art, the present invention by adopting the above-described technical solution, there is an advantage in that:
1) kettle body body uses vertical arrangement, can be by granular lignite in bulk from upper by belt conveyor
Port is sent directly into kettle, and thoroughly avoiding horizontal steam-cured kettle needs first to load the trouble that could send into lignite in kettle with container;
Not only improve powder feeding efficiency but also can have been filled up in space in kettle automatically using lignite free-falling, and improve the volume of steam-cured kettle
Utilization rate.
2) due to being provided with openable bottom in the lower port of kettle body body, thus it is straight using the own wt of lignite
Run in material, not only convenient and swift but also improve discharging efficiency.
3) due to adding electrode in kettle body body, therefore it can be avoided because of electrochemical reaction using accessory power supply
The defect for causing kettle body body to be corroded and damaged, extends service life.
4) due to adding the nitrogen gas generating device connected with kettle, therefore can be by vacuum after drying and upgrading is finished
Pump will be vacuumized in kettle, and inject nitrogen filling lignite crack and texture;Thoroughly prevented lignite dieseling, it is ensured that storage and
Transport safely at a distance.
5) adjacent two-stage steam-cured kettle is connected as a result of external pipe, arrived when the upper level steam-cured kettle heat-insulation pressure keeping time
Remaining pressure and heat can be oriented to by next stage steam-cured kettle by external pipe after up to sets requirement and realize UTILIZATION OF VESIDUAL HEAT IN;Together
When, air water then can be guided to moisture separator by being evacuated drain pipe and reclaim hot water by the residual compression of upper level steam-cured kettle, and
Boiler is returned to recycle.Therefore UTILIZATION OF VESIDUAL HEAT IN is abundant, save the energy.
