Description
Technical field
After the utility model relates to waste incineration and generating electricity produce the safe disposal of flying ash, the system of specifically a kind of flyash curing process.
Background technology
Incineration of refuse flyash is at the material that recuperation of heat utilizes system, flue gas purification system to collect after consumer waste incineration.The generation of flying dust with rubbish kind, burn condition, burn the type of furnace and flue gas treating process relevant, generally account for 3% ~ 5% of waste incineration amount.Analysis shows: incineration of refuse flyash is not chemically inert material, wherein have content higher, the multiple harmful heavy metal material such as Cd, Pb, Zn, Cr that can be flooded out and salt, if deal with improperly, heavy metal transformation will be caused, polluted underground water, soil and air.
Traditional flyash curing treatment system by after abundant mix and blend is carried out to flying dust, cement and water through belt be sent to carry out between aging vehicle aging, after aging by transport vehicle transports to refuse landfill landfill.Flying dust after tradition flyash curing system process, moisture content reaches about 27%, but due to the flying dust handled well be Powdered, can dust be produced in the process of transport, cause the destruction of surrounding environment.Meanwhile, be used alone cement solidification system, along with the extension heavy metal of time can slowly leak out, thus again cause the pollution of environment, its harm can not be eliminated completely.
Utility model content
Utility model object: for the problems referred to above, the utility model provide a kind of safe, effective must process flying dust and do not produce dust pollution, system that heavy metal free oozes out.
Technical scheme: a kind of flyash curing treatment system, comprise flying dust storage silo, cement storage silo, discharger, scale hooper, agitator, surge bunker, vibratory sieve, finished bin, chelating agent feedway, comminutor, bucket elevator, described flying dust storage silo, described cement storage silo is connected with described scale hooper respectively by described discharger, the outlet of described scale hooper, described chelating agent feedway is connected with described agitator respectively, described agitator, described surge bunker, described comminutor, described vibratory sieve, described finished bin connects successively, described vibratory sieve is connected with described surge bunker by described bucket elevator.
Further, in order to better convey materials, between vibratory sieve and finished bin, be provided with chain bucket conveyer, between cement storage silo and scale hooper, be provided with auger conveyor, bucket elevator and vibratory sieve, between bucket elevator and surge bunker, be equipped with auger conveyor.
Further, in above-mentioned treatment system, chelating agent feedway comprises chelating agent preparation tank, chelating agent fluid reservoir, and chelating agent preparation tank is connected with chelating agent fluid reservoir, and chelating agent fluid reservoir is connected with agitator.
Further, in order to make the interpolation of chelating agent more accurate, between chelating agent fluid reservoir and agitator, measuring pump is provided with.
Further, the discharger used is Star-like unloader.
In addition, whole treatment system, controls flying dust storage silo, cement storage silo each parameter state such as material level separately by PLC, to save manpower management, realizes continuous operation.
Beneficial effect: compared with prior art, the utility model has the advantages that simple to operate, easy to use, and before overcoming, powder flies to occur that flying dust is revealed in the process being transported to landfill yard, affects the problem of surrounding environment.This system coordinates the practicable unattended operation of robot control system(RCS) simultaneously, is greatly improving the quality of products and is also saving manpower while efficiency.Heavy metal in the flying dust of this system process can have long-term stability, overcomes overlong time in the past, the problem that heavy metal slowly leaches, can more effective Control pollution.
Accompanying drawing explanation
Accompanying drawing is the utility model structure principle chart.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As shown in drawings; a kind of flyash curing treatment system; primarily of flying dust storage silo, cement storage silo, Star-like unloader, scale hooper, agitator, surge bunker, vibratory sieve, chelating agent feedway, comminutor, finished bin composition, wherein chelating agent feedway is made up of chelating agent preparation tank, chelating agent fluid reservoir.In addition, for convenience of the conveying of flying dust, treatment system also comprises an ash inlet tube road.
The outlet in flying dust ash inlet tube road is connected with flying dust storage silo, and the outlet of flying dust storage silo is connected with flying dust scale hooper after Star-like unloader, is connected after the outlet of cement storage silo is connected with auger conveyor with cement scale hooper.The outlet of flying dust, cement scale hooper is connected with the entrance of flying dust mixing agitator.Chelating agent preparation tank is connected with chelating agent fluid reservoir, and chelating agent fluid reservoir is connected by the entrance of measuring pump with flying dust mixing agitator.The outlet of flying dust batch mixing agitator is connected with surge bunker, and surge bunker outlet is connected with comminutor, and comminutor outlet is connected with vibratory sieve.Also be connected by bucket elevator between surge bunker with vibratory sieve.More specifically, bucket elevator is all connected with auger conveyor with between surge bunker and vibratory sieve.Vibratory sieve outlet is connected with chain bucket conveyer, and the outlet of chain bucket conveyer is connected with finished bin.
In the operation of flyash curing system, first flying dust enters flying dust storage warehouse by flying dust ash inlet tube road and stores, enter flying dust scale hooper through Star-like unloader again to weigh, cement is squeezed into cement bin by cementing truck and is stored, enter auger conveyor through Star-like unloader and be delivered to the weighing of cement scale hooper, load weighted flying dust and cement enter in mixer.Chelating agent prepares in chelating agent preparation tank, then enters chelating agent fluid reservoir and stores, during use, add mixer by measuring pump, carry out abundant mix and blend, after stirring, enter surge bunker with flying dust, cement, then enter comminutor and carry out granulation.A material part after comminutor is shaped; a part can not be shaped completely; the particle be shaped enters chain bucket conveyer by vibratory sieve screening and is delivered to finished bin; unfashioned particle enters below auger conveyor by screen cloth gap and is delivered to bucket elevator; enter surge bunker by the auger conveyor of bucket elevator through top again, carry out granulation again.
Parameter in whole system, as flying dust storage warehouse, cement storage silo material level, the jet velocity of measuring pump, the stir speed (S.S.) etc. of agitator all controlled by PLC, to save manpower management, realize continuous operation.Heavy metal in flying dust is through chelating agent effect, and through cement solidification, more stable.Simultaneously that mixture pelleting is shaping, well solve the phenomenon of dust in transit, avoid secondary pollution.
