Abstract
The utility model relates to a kind of fossil-fired unit pollutant complex control systems.Large-sized Coal-fired Power group generallys use desulfurization after furnace at present, but desulfurization technology does not have revolutionary breakthrough.The utility model includes efficient minerals separation machine, boiler, flue, inertia separator, out of stock reactor, air preheater, deduster, desulfurizer and chimney.Raw coal is sieved using efficient minerals separation machine first, isolates cleaned coal, coal dust and spoil, the sulphur content of raw coal and ash content are greatly lowered after screening；Obtained cleaned coal and coal dust enters boiler furnace burning, and the sulfide and dust generated after burning is greatly lowered；There are the dust of bulky grain for the flue gas of generation, separate the large dust particle in flue gas by inertia separator, reduce influence of the flue gas to out of stock reactor；Flue dust and sulfide are further removed by deduster and desulfurizer later.The utility model can reduce the generation of pollutant from source, reduce the operating pressure and cost of follow-up equipment.
Description
Technical field
The utility model relates to a kind of fossil-fired unit pollutant complex control systems, high more particularly, to a kind of burning
The system of fossil-fired unit sulfide and the comprehensive dust control of sulphur high ash coal.
Background technique
Southwestern China area coal quality is influenced based on sulphur coal by communications and transportation etc., southwest fired power generating unit
The average sulfur content for carrying out coal is generally higher than design coal, and which results in SO in flue gas2Concentration it is higher, be on the one hand that coal quality contains
Sulfur content is generally higher, is on the other hand SO2Discharge standard is continuously improved, fossil-fired unit SO2It is more and more severeer to discharge situation,
Unit emission reduction is huge, and such as application No. is 201720890752.9 Chinese patents.Large-sized Coal-fired Power group generallys use at present
Desulfurization technology path after furnace, but desulfurization technology does not have revolutionary breakthrough, is deteriorated in increasingly strict discharge standard and coal quality
It is single to be difficult by desulfurization after furnace by SO under dual-pressure2Control in effluent standard hereinafter, even if controlling, desulphurization system
It is that at full capacity or overload operation, system pressure is big, be easy to cause the system failure, the anti-corrosion pressure and environmental protection that unit is born subtracts
Arrange increased pressure, the security and stability decline of equipment.Therefore, Large-sized Coal-fired Power group needs a variety of desulfurization technological means cooperations, reaches
To jointly controlling SO2Purpose.With the control of discharged nitrous oxides, the configuration of out of stock equipment is set especially with SCR is out of stock
Standby extensive use puts forward new requirements the control of flue gas flying dust, and the control of flue gas flying dust, needs especially before SCR device
Finding better approach reduces abrasion and blocking of the flying dust to the out of stock reactor of SCR.Sulphur content is reduced for furnace wall cooling high temperature
Corrosion and the corrosion in cigarette air duct can all have reduction effect.The reduction of ash content has positive effect to back-end ductwork blocking is improved, simultaneously
It can reduce the abrasion of heating surface and the abrasion of flue.
Utility model content
The purpose of the utility model is to overcome the above deficiencies in the existing technologies, and it is reasonable to provide a kind of design
Fossil-fired unit pollutant complex control system.
The technical scheme in the invention for solving the above technical problem is: a kind of comprehensive control of fossil-fired unit pollutant
System processed, which is characterized in that including efficient minerals separation machine, boiler, flue, inertia separator, out of stock reactor, air preheater,
Deduster, desulfurizer and chimney；The efficient minerals separation machine is connected to boiler, and the boiler is connected to flue, the cigarette
Road is connected to chimney；The inertia separator, out of stock reactor, air preheater, deduster and desulfurizer are sequentially arranged in flue
On.
It furthermore, further include run coal bin and waste bin, the run coal bin is connected to efficient minerals separation machine, the height
Effect minerals separation machine is connected to waste bin.
A kind of working method of fossil-fired unit pollutant complex control system as described above, which is characterized in that institute
It is as follows to state working method:
(1) raw coal is sieved using efficient minerals separation machine first, cleaned coal, coal dust and spoil is isolated, through being sieved
The sulphur content of raw coal and ash content are greatly lowered after point；
(2) enter boiler furnace burning, the sulfide and powder generated after burning by cleaned coal obtained after separation and coal dust
Dirt is greatly lowered；
(3) flue gas that generates is there are the dust of bulky grain after burning, by inertia separator by the bulky grain powder in flue gas
Dirt separation reduces influence of the flue gas to out of stock reactor；
(4) flue dust and sulfide are further removed by deduster and desulfurizer after.
The utility model compared with prior art, has the following advantages that and effect: the utility model provides a kind of fire coal
The system and method for pollutant comprehensively control can reduce the generation of pollutant from source, reduce subsequent electric precipitation and desulfurization
The operating pressure and operating cost of equipment.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing and by embodiment, and following embodiment is pair
The explanation of the utility model and the utility model is not limited to following embodiment.
Embodiment.
Referring to Fig. 1, a kind of fossil-fired unit pollutant complex control system, including efficient minerals separation machine 1, boiler 2,
Flue 3, inertia separator 4, out of stock reactor 5, air preheater 6, deduster 7, desulfurizer 8 and chimney 9；The efficient mineral point
It disembarks and 1 is connected to boiler 2, the boiler 2 is connected to flue 3, and the flue 3 is connected to chimney 9；The inertia separator 4 takes off
Pin reactor 5, air preheater 6, deduster 7 and desulfurizer 8 are sequentially arranged on flue 3.
It further include run coal bin and waste bin, the run coal bin is connected to efficient minerals separation machine 1, described in the present embodiment
Efficient minerals separation machine 1 is connected to waste bin.
The working method of above-mentioned fossil-fired unit pollutant complex control system is as follows:
