Description
Technical field
The present invention relates to a kind of preparation method of material of construction, particularly relate to a kind of preparation method adding city sludge vitrified brick.
Background technology
The mud that municipal sewage plant produces is a great problem of puzzlement urban environment always, in some areas, the disposal costs of mud is also a no small number, secondary pollution will be caused if dealt with improperly, find through detecting, municipal sludge has the organic matter of certain thermal value, and has the more objectionable impurities to environment.Sludge resource can be utilized, not cause secondary pollution again, the manufacturing process of adding making brick from sludge is a kind of processing mode of comparatively giving prominence to.
In existing municipal sludge brickmaking technology, adopt the drying and roasting kiln general step that automatically control: first mud is made processed, maybe the mud of degraded, anaerobic treatment is remake processed, then be uniformly mixed, shaping clip, enters dry kiln, roasting finished product.Mud early stage in this class technique need be degraded, anaerobism, drying treatment, mud open-assembly time is longer, environmental Kuznets Curves ensures and is difficult to reach re-set target, and modernization brickkiln is all automatic continuous control, output is larger, add 40%-60% mud, first mud continues a large amount of supplies is exactly a raw material supply problem, as directly reduce or without mud, in lasting roasting kiln, original technical parameter setting, by the generation of builder caused in batch, as adopted artificial technology to regulate, its quality product is also difficult to stable guarantee.In the composition of mud, organic volatile component is comparatively large, and a large amount of mud that adds will cause finished bricks sizing unstable, and compare with the common brick fired with less interpolation mud, its quality does not have advantage yet.
Summary of the invention
The object of this invention is to provide and a kind ofly can reduce mud impact on environment in disposal process, require less to the technical parameter of the drying of the automatic control of persistence and roasting kiln, to a kind of preparation method adding city sludge vitrified brick that the lasting supply guarantee of mud and the quality of finished bricks of adding firing sludge are all greatly improved.
For achieving the above object, the technical solution used in the present invention is: a kind of preparation method adding city sludge vitrified brick, is characterized in that, comprise the following steps:
The first step, pours into sludge agitation pond by mud, add water uniform stirring, treats that sludge moisture content reaches 80%-90%, extracts the thermal value of mud in this pond and organic volatile quantity;
Second step, joins the shale by proportioning collocation and making coal gangue brick raw material by the mud of the water content 80-90% extracting thermal value and volatile quantity, be uniformly mixed to grind and practice homogenizing, then be sent to the ageing of ageing storehouse, wherein the content of mud accounts for the 1%-10% of gross weight;
3rd step, adds in vacuum extruder by the brick producing material after ageing, and extrusion moulding obtains wet adobe;
4th step, dry, send the kiln car of good for code adobe to dry kiln, utilize roasting kiln waste heat dry 20-24 hour in the hot blast of 100-150 DEG C;
5th step, roasting, sends dried adobe to roasting kiln, and maturing temperature is that 1000-1100 DEG C, roasting time 24-28 hour obtain sintered article.
Advantageous effect of the present invention is: owing to employing preparation method of the present invention, early stage, sludge disposal decreased drying and other treatment, less on the impact of environment, because using oven dry and the roasting kiln of the automatic control of persistence, higher to the component requirements stability of brick, mud enter agitated pool add add water to water content at 80%-90% time, the thermal value of mud in this pond and organic volatile quantity are extracted to it; The thermal value of mud determines the addition of mud, the size of organic volatile quantity determination adobe size.General according to mud thermal value, determine that mud adds the content of 1%-10%, the less quality of interpolation mud to finished bricks has higher guarantee.Mud is added in raw material, in the alternative brick-making raw material of its thermal value, the content of coal gangue, so saved starting material, has also reduced production cost, can be long-term have a good guarantee to the use of mud, thus obtain the achievement of the economic benefit of enterprise and the environmental benefit double combination of society.
