The utility model provides a waste material carbide slag that produces of power plant can utilize by the secondary, realized salvaging, practiced thrift the energy, when the carbide slag use is not enough, can utilize the lime stone system to supply, satisfied desulfurization system's application.
Description
Technical field
The utility model relates to flue gas desulfurization technique field, particularly relates to carbide slag and limestone desulfurizer device for interchanging in wet process of FGD.
Background technology
Existing domestic calcium carbide method acetylene production certainly leads to ancillary industry refuse carbide slag (slurry), carbide slag (general) mainly contain two digestion approach at present.One is form the raw materials for production of dry slag as building materials such as cement using after carbide slag slurries dehydration; Two is use substituting the desulfurizing agent of calcium carbonate as power plant desulphurization system after carbide slag slurries filtration, purification.
In carbide slag slurries, the composition of solid particle is very complicated, and except calcium hydroxide, calcium oxide, also containing all kinds of solid particle such as carbon slag, silicon iron, its granularity size has distribution from several microns to tens millimeters.And carbide slag slurries is when using as desulfurizing agent, the solid particle being greater than 40 microns can produce the adverse consequences such as wearing and tearing, blocking to the pipeline of power plant desulphurization system and the desulfurizing agent circulatory system, therefore, harmful bulky grain must be extractd the desulfurization instructions for use that just can meet power plant by purification by carbide slag slurries.
The production key issue of carbide slag desulfurizing agent is how low cost, low energy consumption are extractd not meeting the bulky grain that power plant desulfurization requires in carbide slag.Treating method conventional at present has sedimentation separation, grinding, isolated by filtration etc.
Utilize the difference of granular mass size in carbide slag slurries to carry out natural subsidence, bulky grain is deposited in bottom slurries, extract the suspension of middle and upper part carry out concentrated after for power plant desulfurization.This method is at the bottom of the utilization rate of carbide slag, and how the carbide slag slurries of sedimentation processes remains a large problem.
The mode of mechanical crushing is adopted bulky grain in carbide slag to be ground into the grain fineness meeting desulfurization and require.This method efficiency is high, but the equipment of milled particles adopts the mechanism of filtering, and carries out interception extract bulky grain undesirable in carbide slag slurries.This method production efficiency is high, energy consumption is low.But because carbide slag slurries is rear pulpous state, needs again to retain granule filtering oarse-grained while, therefore also only have the production that indivedual specialized factory can adopt the method low cost of isolated by filtration, carbide slag desulfurizing agent is carried out in low energy consumption at home at present.
Carbide slag desulfurizing agent can replace agstone, is directly used in existing lime stone---and gypsum method flue gas desulfurization device, need not carry out large transformation to original device.There are wide market prospects.Also a new recycling treatment approach will be opened up for this industrial waste of carbide slag.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide carbide slag and limestone desulfurizer device for interchanging in a kind of wet process of FGD, this device ensure that the calcium carbide quantity of slag affects desulfurization less, and also waste recycling simultaneously, has saved the use of limestone desulfurizer.
The purpose of this utility model is realized by following technical scheme:
Carbide slag and limestone desulfurizer device for interchanging in a kind of wet process of FGD, comprising: carbide slag pulping system and lime stone store and induction system; Described comprising of carbide slag pulping system stock tank, intermediate pool, spin vibration sieve, slurry pool and slush pump;
Describedization stock tank is changed stock pump by one and is connected with described spin vibration sieve, and this spin vibration sieve is also connected with described intermediate pool;
Described intermediate pool is connected with described slurry pool by line pump;
Described slurry pool connects desulfurizer by slush pump.
Compared with prior art, one or more embodiment of the present utility model can have the following advantages by tool:
When ensureing not affect flue gas desulfurization, utilizing waste carbide slag as desulfurizing agent, achieving twice laid, also solve flue gas desulfurization in power plant can the requirement of qualified discharge simultaneously.
Accompanying drawing explanation
Fig. 1 is carbide slag and limestone desulfurizer system architecture device for interchanging schematic diagram.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with embodiment and accompanying drawing, the utility model embodiment is described in further detail.
As shown in Figure 1, be that carbide slag pulping system structure and lime stone store and induction system structure, comprise: carbide slag pulping system and lime stone store and induction system; Described comprising of carbide slag pulping system stock tank 1, intermediate pool 3, spin vibration sieve 5, slurry pool 6 and slush pump 7; Describedization stock tank is changed stock pump 2 by one and is connected with described spin vibration sieve, and this spin vibration sieve is also connected with described intermediate pool; Described intermediate pool is connected with described slurry pool by line pump 4; Described slurry pool connects desulfurizer by slush pump.
Above-mentioned lime stone stores and induction system comprises: place the limestone powder bin 8 of agstone 16, roof scrubber 9, sulfuration blower fan 10, Star-like unloader 14 and screw(-type) feeder 15;
Described roof scrubber is arranged on the top of described limestone powder bin;
The lower end of described limestone powder bin is connected with push-pull valve;
Described sulfuration blower fan connects limestone powder bin by an electric heater 11;
Described Star-like unloader is connected with push-pull valve and screw(-type) feeder respectively.
Above-mentioned push-pull valve comprises hand operated gate valve 12 and pneumatic gate valve 13.
Said apparatus implementation process is: after factory spent material calcium carbide slag dry powder 17 is mixed by adding water by Cemented filling to change stock tank, form carbide slag solution, after precipitation, oarse-grained solution will sink, bottom solution is delivered to spin vibration sieve by line pump and makes bulky grain be sized out, fine grained solution enters intermediate pool, by line pump, the carbide slag solution configured is delivered to slurry pool to store, recycles slush pump when desulfurizer needs and be delivered to desulfurizer 18.
When spent material calcium carbide slag can not meet desulfurizer needs, lime stone stocking system is opened and carries out slurrying in order to desulfurizer use.
When lime stone is outsourcing product, need in advance lime stone to be bought to be stored into limestone powder bin, during limestone powder bin material loading, roof scrubber carries out dedusting work automatically, hand operated gate valve following for powder storehouse and pneumatic gate valve and Star-like unloader are opened, by lime stone by being transported to of screw(-type) feeder conveyer stock tank.
