Description
Technical field
The utility model relates to clean moulded coal technical field more particularly to a kind of modified clean moulded coal systems of processing.
Background technique
Currently, China's most area haze is serious, environmental problem is increasingly valued by people.In China atmosphere master
It wants in pollutant, about 80% sulfur dioxide, 60% nitrogen oxides, 50% fine particle derive from coal burning.It is coal-fired
The control of coal-smoke pollution caused by Industrial Boiler and household coal or improvement become more important and urgent.
Country, which increases, in recent years administers coal-burning power plant's pollution dynamics, puts into effect severe environmental protection policy successively, is distinctly claimed combustion
Coal-fired plant realizes " minimum discharge " comprehensively.However, to the civilian and coal-burned industrial boiler pollutant emission of scattered coal is largely used
It administers, due to having a large capacity and a wide range, there is presently no effective control measures.
According to statistics, " scattered coal " every annual consumption accounts for the 20% of national coal consumption amount, phase between 6 to 700,000,000 tons at present in the whole nation
When the pollution generated in about 60 to 12,000,000,000 tons of coal concentrated combustion.Related data is shown, in the inefficient scattered coal in some rural areas in China
The pollutant of burning and exhausting accounts for 25% or more of the main total composition of haze, is the one of the major reasons for causing haze weather.
In order to control scattered coal burning pollutant, related Coal Quality standard, common demands raw coal sulfur-bearing are put into effect in various regions in succession
Amount is not more than 0.4%.Since scattered coal burning is without sulfur dioxide Mitigation options, even if sulfur content, less than 0.4%, directly burning is arranged
The sulfur dioxide put also in 600 to 1000mg/Nm3 (6% benchmark oxygen content), the discharge standard that is required much higher than coal-burning boiler (<
100mg/Nm3, minimum discharge: < 35mg/Nm3).Therefore, in the case where scattered coal burning direct combustion is in line, high-quality low-sulfur coal is not
Equal to Filter Tuber For Clean Coal.
Clean moulded coal technology is one of important channel of coal-cleaning utilization.Coal utilization can be improved using clean moulded coal
The thermal efficiency, energy conservation 15 to 30%, flue gas lingemann blackness drops to 1 hereinafter, dust, SO2, CO and NOx discharge can be big after burning
Width reduces.Therefore, to improve coal-fired utilization efficiency, the pollutant emission of Industrial Boiler and household coal is reduced, various regions government is close
Clean moulded coal technology is widelyd popularize over year.However current clean moulded coal technology there are raw materials selectively narrow, at high cost, coal quality is not
Stabilization, combustibility, bad the problems such as making, it is difficult to promote and apply.
Currently, wet process briquette preparation technology is widely used in domestic moulded coal factory.But the technique there are following point and
It is insufficient: to need heat source to dry moulded coal, environmental issue can be brought by providing thermal energy using coal-burning boiler, if installation fume treatment
Facility, will increase investment and consume a large amount of desulfurization denitrification agents etc.；Need to add binder to improve briquette strength, effect is good to glue
It is generally higher to tie agent cost；Anthracite is all made of as moulded coal raw material, preparation cost is high, and because anthracite volatile matter is low, uses
When there is a problem of that igniting is difficult；Big ball is generallyd use, intensity is big, but there are non-burn-through problems.
China has coal resources abundant especially low-quality coal resources, such as a large amount of coal slime, smalls, mixed coal, sulphur coal
Deng.These coal resources, due to the limitation of coal characteristic, market sale is unsmooth, not only waste of resource, but also derives two sometimes
Secondary pollution forms very big environmental burden.
Utility model content
In order to overcome the drawbacks of the prior art, the purpose of the utility model is to provide a kind of clean moulded coal systems.This is practical
Novel proposition is using the coal resources abundant inferior such as bituminous coal and sulphur coal, by the side for adding compound additive inside coal dust
Method is equally even more than anthracite briquette after achieving the purpose that coal burning.The technique uses coal dust dry method mesolow, soap-free emulsion polymeization
Agent, no drying moulding process.
The utility model embodiment provides a kind of modified coal system of processing, wherein the system comprises: coal blending crushes dress
It sets, compound additive preparation facilities, dispersing mixer, molding machine, in which: the input end of the coal blending grinding device is used for
Feed coal is received, the outlet end of the coal blending grinding device is connect with the first input end of the dispersing mixer, described multiple
The input end of additive preparation facilities is closed for receiving additive raw material, the outlet end of the compound additive preparation facilities and institute
State the second input end connection of dispersal device, the input end company of the outlet end of the dispersing mixer and the molding machine
It connects.
Preferably, the system also includes cooling device, the input end of the cooling device and the molding machine go out
The connection of mouth end.
Preferably, the coal powder crushing device of matching is hammer mill, double-roll crusher, rotor flour mill, Vertical Mill, Lei Meng
It grinds one such.
Preferably, the dispersing mixer is that twin-shaft mixer, plough coulter type blender, V-type batch mixer, double movements are mixed
Conjunction machine is one such.
Preferably, the molding machine is that roller briquetting machine, impact type molding machine are one such.
The system of processing and its processing method of clean moulded coal provided by the utility model embodiment, its advantages are such as
Under:
The purpose of this technology is using low-quality coal resources such as sulphur coal, mixed coal, smalls and coal slime etc., in conjunction with composite chemical
Additive is simultaneously prepared into high effective and modified clean moulded coal by dispersing mixer, molding machine.For improve Industrial Boiler coal and
The clean utilization and energy conservation of household coal are provided with effect approach, realize Coal Industrial to purifying industrial transformation liter for coal enterprise
Grade, wound effect, which increases income, opens up new approach.
