Description
Technical field:
The invention belongs to field of material technology, and in particular to a kind of clinker calcined using rice husk as crude fuel and its forge
Firing method.
Background technique:
As the cement of one of the big basic material of building industry three, yield also with construction industry development and constantly increase
It is long.Cement industry is resource and energy consumption type industry, and cement is to add proper amount of gypsum by clinker, also plus is in right amount mixed sometimes
Material it is common it is levigate made of, the main crude fuel of clinker production is lime stone, siliceous raw material (such as clay) and coal, this
It is all a bit non-renewable natural mineral resource.
Resource and environment are the two principal themes of human development, and the mankind need to reduce resource consumption, protection environment, preserve our planet.
Building material industry is high energy consumption, the industry of maximum discharge as national economy important foundation.Wherein, cement industry is resource consumption
One of the rich and influential family that huge, greenhouse gas emission severely exceeds.Therefore new material, new technique are found to reduce cement industry pair
The consumption of resource and the pollution of environment are imperative.
Rice husk is that rice is processed into remaining principal by product after rice, and rice husk accounts for about the 20% of paddy kernel weight.Often
At 200,000,000 tons or so, the amount for generating rice husk is about 40,000,000 tons for year China's rice yield.
The nutriments such as the crude protein, the crude fat that contain in rice husk are very few, both can not provide energy or nothing to animal
Method provides protein, but also contains a large amount of plant fiber, is directly fed for animal, animal is difficult to digest, to cause stomach
Discomfort, therefore rice husk can not be used as the main raw material of animal feed.In rural area, the conventional process mode of rice husk is not separate rice husk
And straw, it mixture is dried to be placed in burner hearth carries out burning as fuel and is used to heat up water and cooks or burn a heatable brick bed, burn surplus ashes
It then may be used as the adsorbent of human and animal excreta, be finally also used as fertilizer and return to field, but when rice husk total amount is more, this
Kind way is just no longer applicable.Directly it can bury or burn in field when usually rice husk total amount is more, combusting rice hull can generate
CO2, and burn the rice hull ash generated and can raise and drifted to surrounding with the wind, thus this way not only occupy land resource but also
Environment is also polluted, environmental pressure is caused, currently, China handles rubbish, it is per ton to need 50~150 yuan of cost.
With the progress of science and technology, people gradually recognize the potential value of rice husk, and rice husk power generating is exactly example, 2t's
Rice husk can produce the heat for being equivalent to 1t standard coal, and the rice husk of 2~3kg can generate electricity 1kWh, but rice husk power generating can generate powder
Coal ash needs to make secondary treatment.Even if a small amount of rice husk is used as power generation, the utilization rate of rice husk is still very low, can not also eliminate rice husk
To immense pressure caused by environment.
Summary of the invention:
In view of the deficienciess of the prior art, the present invention provide a kind of clinker calcined using rice husk as crude fuel and its
Method for calcinating.The invention using rice husk as production Portland clinker one of raw material, substitution part of clay matter raw material and
Part coal, calcination of cement clinker can not only reduce the usage amount of mineral resources, but also can reduce the rice husk directly burned
Amount, so that the discharge for the carbon dioxide that economizes on resources, reduces, plays the role of protecting environment.Moreover, rice husk is used for manufacture of cement,
It will not be directly becoming clinker as generating the secondary wastes objects such as flying dust for generating electricity, primary environmental protection is in place.
