Description
Technical field
The invention belongs to industrial solid wastes high-temperature process technical fields, and in particular to one kind is based at industrial exhaust heat collaboration
Set the system and method for solid waste preparation cementitious material.
Background technique
Disclosing the information of the background technology part, it is only intended to increase understanding of the overall background of the invention, without certainty
It is considered as recognizing or implying in any form that information composition has become existing skill well known to persons skilled in the art
Art.
The fast development of China's economy, advancing by leaps and bounds for industry advance the development of modernization construction and improve the people's
Living standard, comfortable environment increasingly become the needs of people's life.While industrial development consumes vast resources, also produce
Given birth to a large amount of Industrial Solid Waste and high-temp waste gas, high-temp waste gas is generally required purified using waste gas treatment equipment after could arrange
It puts, but the technique of general waste gas treatment equipment requires gas temperature cannot be excessively high, so, exhaust gas higher for temperature needs
Cooling processing is carried out, the cooling method of exhaust gas generally comprises directly contact cooling and mediate contact and cools down two kinds, directly contacts
Cooling is that flue gas is directly contacted with cooling medium, and carries out heat exchange, and e.g., spraying cooling is carried out using the spray form of convection current
Cooling, this kind of method cost of equipment is low, and space occupied is small, can strictly and promptly control temperature, but equipment is held in operational process
Perishable, recirculated water is enriched with pollutant for a long time and forms secondary pollution etc.；Dilution cooling, is mixed into some cold wind in high-temp waste gas,
To make high-temperature gas be cooled down, this kind of method is simple and easy, and cost of equipment and operating cost are low, but increases gas stream
Amount, increases follow-up equipment capacity.Mediate contact cooling is that flue gas does not contact directly with cooling medium, generally using heat exchanger into
Row heat exchange, does not change the property of flue gas, but bad to the cooling effect of flue gas.
Industrial Solid Waste include blast furnace slag, steel slag, red mud, non-ferrous metal slag, flyash, cinder, waste gypsum, carbide slag and
Salt slurry etc., the substantial amounts of Industrial Solid Waste, complicated component, processing are difficult, and the passive stockpiling of Industrial Solid Waste does not only take up a large amount of soil
Ground, and contain substance soluble easily in water in Industrial Solid Waste, it is easy to pass through leaching contaminated soil and water body.In addition, high-temperature steel slag
Temperature it is higher, but utilization rate of waste heat is lower, generally using the side such as hot application method, tray method, wind quenching method, drum process, shotting
Method is handled, and hot application method is short cooling time, and treating capacity is big, but reaction is not closed, and environmental pollution is serious, and treated steel slag
Stability is poor；Tray method treating capacity is big, but plant maintenance amount is big, explosive, environmental pollution is serious；Wind quenching method, water quenching, roller
Method and shotting are only applicable to the liquid slag of good fluidity.
So the processing of high-temp waste gas and Industrial Solid Waste can all occupy a large amount of manpower, material resources and financial resources, and more difficult provided
Sourceization utilizes.
Summary of the invention
For above-mentioned the technical problems existing in the prior art, the object of the present invention is to provide one kind to be assisted based on industrial exhaust heat
With the system and method for disposition solid waste preparation cementitious material, existed using the waste heat in high-temperature tail gas and high-temperature steel slag to all kinds of solid wastes
It preheated, be carbonized in grinding process, improve the activity of solid waste, realize the resource utilization of solid waste, and can be to high-temperature tail gas
Cool down, energy-saving and emission-reduction.
