Description
Technical field
The invention belongs to soil remediation fields, and in particular to a kind of side using the swollen pearl improvement soil of high-titanium blast furnace slag
Method.
Background technology
Soil improvement is to improve the physics of soil, chemistry and biological property, it is made to be more suitable for plant growth, effectively
Ground improves soil moisture content, increases topsoil ground temperature, shifts to an earlier date Crop growing stage, and soil moisture increases, while can also improve soil knot
Structure coordinates the relation between the soil water, fertilizer, air and heat and biology, prevents erosion, and enhances anti-seepage of channels ability, inhibits soil
Secondary salinization improves the utilization of sandy bare land.
High-titanium blast furnace slag is when climbing steel ordinary blast to smelt vanadium titano-magnetite, and the melted gangue of generation is natural in air
A kind of fine and close slag with some strength that cooling or water cooling are formed.With ordinary blast slag ratio, titanium dioxide in steel climbing high slag
Titanium (TiO2) content is up to 20%~24% (since high-titanium blast furnace slag titaniferous amount is high, also referred to as high-titanium dry slag), calcium oxide
Content is relatively low, i.e. the grain slag of raw material production belongs to non-active material, and therefore, climb steel has more than 5,500 ten thousand tons of high titania type height so far
Clinker is not utilized, it takes up an area thousands of mus, and it is annual also increased with 3,000,000 tons of bed drain purge, climb steel and be faced with and nowhere arrange
The situation of slag.Can high-titanium blast furnace slag be integrated into utilizing, and not only influence and climb steel, the sustainable development of Panzhihua social economy
Exhibition, and to saving natural resources, reduce engineering cost, protection Upper Yangtze River ecological environment etc. and be respectively provided with important meaning.
Utilization for high-titanium dry slag, there are two types of different technology paths, have both carried titanium and have utilized and do not propose titanium utilization.
It is utilized for carrying titanium, although realizing the most dreamboat of high-titanium dry slag value, due to current limitation of the technology, utilizes cost
It is high, the consumption of blast furnace slag is also extremely limited, still remaining most slags after titanium is carried, therefore to solve to climb steel slag at present
Bulk deposition, land occupation, the realistic problem for polluting environment, the task of top priority must also walk not carrying the way that titanium utilizes high-titanium dry slag
Footpath.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of soil is improved using trade waste high-titanium blast furnace slag
Method
There is provided a kind of swollen using high-titanium blast furnace slag for technical solution used by the present invention solves above-mentioned technical problem

Wherein, in the method described above using the swollen pearl improvement soil of high-titanium blast furnace slag, the high-titanium blast furnace slag
Swollen pearl is prepared by following methods：
High titania type blast furnace cinder is poured into slag runner, swollen pearl slot is flowed to, then flows on the roller of rotation, rotating cylinder leaf
Piece crushes slag, then casts in the air, sprays water to the slag pearl of aerial sports, slag pearl forms spherical shape, falls into swollen Zhu Chi, carries out
Screening, obtains the swollen pearl of high-titanium blast furnace slag of granularity Wei≤3mm.
Wherein, in the method described above using the swollen pearl improvement soil of high-titanium blast furnace slag, the high titania type blast furnace melts
The temperature of slag is not less than 1000 DEG C.
Wherein, in the method described above using the swollen pearl improvement soil of high-titanium blast furnace slag, the high titania type blast furnace melts
The iron content of slag is no more than 1%.
The beneficial effects of the invention are as follows：
The method of the present invention improves soil using the swollen pearl of high-titanium blast furnace slag, after adding in swollen pearl, energy moisture-locking, and suppression
Moisture evaporation processed, it is ensured that the requirement of plant growth moisture content improves ground temperature, reduces salinity and is accumulated in earth's surface, can be effectively improved plant
Growing state, the soil improvement especially suitable for hillside fields and non-solid water；The method of the present invention efficiently utilizes high-titanium blast furnace slag industry
Discarded object improves the utilization rate of high-titanium blast furnace slag, is worthy of popularization.
Specific embodiment
Specifically, a kind of method using the swollen pearl improvement soil of high-titanium blast furnace slag, this method comprises the following steps：
The swollen pearl of high-titanium blast furnace slag is evenly laid out in upper soll layer, it is ploughed, makes the swollen pearl of high-titanium blast furnace slag and soil
Earth is uniformly mixed, you can.
The method of the present invention improves soil using the swollen pearl of high-titanium blast furnace slag, after adding in swollen pearl, energy moisture-locking, and suppression
Moisture evaporation processed, it is ensured that the requirement of plant growth moisture content improves ground temperature, reduces salinity and is accumulated in earth's surface, can be effectively improved plant
Growing state, the soil improvement especially suitable for hillside fields and non-solid water.High-titanium blast furnace slag is as a kind of trade waste, by it
When being prepared as swollen pearl for soil improvement, to improve the utilization rate of high-titanium blast furnace slag, while ensure reclamation result, this hair
The dosage of the bright swollen pearl of middle high-titanium blast furnace slag is 500~1500Kg/ mus, and controls its granularity Wei≤3mm.
In the method for the present invention, the swollen pearl of high-titanium blast furnace slag is prepared by following methods：
The present invention by smelt iron out temperature for 1000 DEG C and more than high titania type blast furnace cinder transport to cinder field with slag ladle, incline
Slag runner is poured into, swollen pearl slot is then reached, then flows on the roller of rotation, rotating cylinder blade crushes big stock slag, then
Cast aerial, the slag pearl thrown is cooked oblique upper paraboloiding movement in the air, while roller lower part is sprayed water to the slag pearl of movement, and slag pearl meets water
Fast speed is cooled into spherical shape, falls into swollen Zhu Chi, forms the swollen ball of size fractionated, is sieved the height for≤3mm to get granularity
The swollen pearl of titanium blast furnace slag；High titania type blast furnace cinder cannot have solidifying body, otherwise can influence slag fluidity, and drum blade rotation is difficult
Solidifying body to be crushed, it is unfavorable for swollen pearl and is formed.
In addition, cannot have too many iron in high titania type blast furnace cinder, i.e., the iron content in slag is no more than 1%；If high titania type
Iron content is excessively high in blast furnace cinder, is unfavorable for slag and crushes, and also influences the application of swollen pearl；Slag pearl has to during projectile
Injection water, will make slag rapidly cool to form swollen pearl, and water can use common domestic water.
