Description
Technical field
The present invention relates to a kind of flyash production system, the powder processed more particularly to a kind of multiple stage circulation and broken up in advance
Ash ultrafine powder grinding system.
Background technique
Currently, nearly 600,000,000 tons of China's flyash annual emissions.Although whole synthesis utilization rate has reached 70%, in west
Portion and northern coal electricity concentrated area, flyash discharge capacity is big, and utilization rate is very low, gives outdoor stockpiling or landfill mostly, not only dirty
Contaminate environment and waste of resource.
China's stem environmental protection tax law formal execution on January 1st, 2018, enterprise and institution and other productions
The solid waste such as operator's storage or disposition flyash do not meet country and local environment protective standard, need to pay environment
25 yuan/ton of tax of protection.The flyash desulfurized gypsum such as coal-burning power plant discharge unit and associated production operating unit will face huge
Processing with utilize pressure.How to carry out preferably environmental protection to flyash, desulfurized gypsum to dispose and comprehensively utilize, it has also become existing rank
Major issue Duan Hangye of interest.
Flyash can be widely used for cement and concrete, and producing level and technology content are all relatively high, can not only reduce
The cost of concrete, and its workability and durability can be improved, this is undoubtedly the effective way of large consumption flyash.
But be mainly I grade of ash by concrete welcome, and I grade of ash of power plant emission only occupies the minority, remaining cinder activity compared with
Low water demand is more high-leveled and difficult directly to utilize, for using that need to give proper treatment, common processing mode is exactly grinding, but is limited to energy
Consumption is generally only ground to I grade of grey fineness (R45 μm of < 12%).If can economically grind to obtain thinner (R45 μm of < 1%), to fine coal
The utilization of ash itself and the improvement of concrete performance are all of great benefit to, and this is exactly the mission of flyash superfine grinding production line.
Existing flyash production line is first to be dried by roller dryer, then carries out grinding by ball mill.It is former
Beginning flyash gives outdoor stockpiling mostly, very big containing moisture content, due to the limitation of lifting blade structure inside dryer, raw material
Flyash dispersion is bad, and bad so as to cause drying effect, yield does not increase；Flyash quality is light, and powder is more, ball mill
Grinding effect is bad, low output, and power consumption is high, noise is big.Traditional flyash production line, low output, power consumption is high, waste of resource,
Space occupied is big, and equipment investment is high.Energy-saving new normality requirement is not met.

Row saves.
In the embodiment that invention discloses, Fig. 7 and Fig. 1-6 please also refer to, multiple stage circulation is processed and broken up in advance
The grinding process 31 of flyash System of Ultra Thin Power Rubbing 33 are as follows:
Step 311, it feeds.Raw material flyash passes through the valve blanking of bottom storehouse in raw material storage 1, measures, passes through through weighing balance 2
The conveying of first belt feeder 3, the iron remover 4 for being mounted on 3 end of the first belt feeder remove the impurity such as iron block, pass through the first elevator
5 enter the second belt feeder 6, into the raw material flyash of the second belt feeder 6, detect by metal detector 7, if having un-cleared
The impurity such as iron block then discharge the material containing impurity in refuse bin 12, if miscellaneous without iron block etc. by T-piece splitting valve 8
Matter then enters pre- dispersing device 9, is broken up in advance by the stick 92 of breaing up in pre- dispersing device 9 to raw material flyash；
Step 312, it pre-processes.Material after breaing up in advance is introduced into V-type coal pulverizer 10, does not carry out grinding in raw material in this way
Before, it first carries out selecting powder, finished product satisfactory in flyash is first sorted out, share the grinding of 11 a part of vertical roll grinder
Work, to improve the mill efficiency of vertical roll grinder 11, by breaing up grid array 105 and wind to original in V-type coal pulverizer 10
The progress of feed powder coal ash is secondary to break up, by selecting powder grid array 106 to carry out level-one roughing powder；
Step 313, it dries.Raw material flyash into V-type coal pulverizer 10 is dried by hot-blast stove 14, V-type fine coal
The intake stack of machine 10 is composed in parallel by four tunnels, connects hot-blast stove 14 all the way, is connected air cold wind all the way, is connected vertical rolls all the way
The dust removal port of grinding machine 11 connects the first blower 20 all the way, and the first blower 20 is blown into the air quantity of V-type coal pulverizer 10 by the 4th tune
It saves valve 21 to control, this circulated air can effectively compensate the insufficient air quantity of V-type coal pulverizer and heat；
Step 314, grinding and collection.Coarse powder enters vertical roll grinder 11 and carries out extruding grinding, fine powder then with system wind
It is sent to eddy flow powder concentrator 16 together, carries out second level and finely selects powder, the coarse powder come out through eddy flow powder concentrator 16 enters vertical roll grinder
11 grinding, superfine powder finished product then enter in cyclone separator again together with raw material flyash, carry out level-one collection, have not collected
Superfine powder finished product then pass through dust-precipitator 23 and carry out second level collection, the collection Jing Guo two-stage in this way passes through the cigarette with environmental protecting device
The exhaust gas that chimney 25 discharges complies fully with the requirement of environmental protection；The finished product collected through firsts and seconds passes through 28 He of air flume together
Second elevator 29, is transported to warehouse for finished product 30.
Several preferred embodiments of the invention have shown and described in above description, but as previously described, it should be understood that this hair
It is bright to be not limited to forms disclosed herein, it is not to be taken as the exclusion to other embodiments, and can be used for various other
