The carbon residual of body, about 10-30%, other are the impurity such as a small amount of iron, alkali metal.Coal gasification lime-ash is different from flyash, carbon content
Much higher, usual humidity is also also more larger than larger, lime-ash granularity.Coal gasification lime-ash is often loose structure, and specific surface area is larger,
With the good potential quality for making adsorbent.But in this gasification lime-ash of coal chemical industry carried out as solid waste at present
Stack or landfill stabilization, it is not only costly, and cause the huge waste of resource.Make full use of clinker special in itself for this
Some chemical composition or physicochemical characteristics, product of the production with higher economic value, turn waste into wealth, and improve coal resources
Comprehensive utilization ratio, with huge meaning.
The comprehensive utilization of current coal gasification lime-ash also predominantly stays in building materials field, water treatment agent field application mostly
To pass through soda acid and other inorganic material-modified, not only complex process, and easily produce secondary pollution.And because by its grain
The small limitation of degree, with poor resistance, is easily washed away by current, and sedimentation produces the shortcomings of mud results in blockage, and has a strong impact at it
Efficiency is managed, causes the problem of it has larger in engineering application.
The content of the invention
For problems of the prior art, the present invention provide a kind of water treatment absorbent based on coal gasification lime-ash and
Its preparation method, is easy to implement, with low cost, realizes the comprehensive utilization to coal gasification lime-ash, makes full use of lime-ash peculiar in itself
Chemical composition or physicochemical characteristics, product of the production with higher economic value reach the standard of engineer applied, change give up into
Treasured, improves the comprehensive utilization ratio of coal resources.
The present invention is to be achieved through the following technical solutions：
A kind of water treatment absorbent preparation method based on coal gasification lime-ash, comprises the following steps,
Step 1, coal gasification lime-ash is mixed evenly with concentration for 0.1-0.5% polyacrylamide solution and mixed
Compound；The mixed proportion of polyacrylamide solution and coal gasification lime-ash is pressed per 10ml polyacrylamide solution mixed gas ashing slags
100-10000 grams；
Step 2, addition concentration is 30%-60% ptfe emulsions in the mixture, continues to stir, mixes in right amount
Water, makes the slurry of mixture pulp；The volume ratio of ptfe emulsion and polyacrylamide solution is 3：1 to 1：3；
Step 3, slurry is molded by extrusion shearing, then the water based on coal gasification lime-ash in stripping and slicing shape is obtained after drying
Handle adsorbent.
It is preferred that, in step 3, slurry before the forming, static aquation 1-4 hours.
It is preferred that, in step 3, temperature during drying is 50-90 degrees Celsius.
It is preferred that, in step 2, the volume ratio of ptfe emulsion and polyacrylamide solution is 1:1.
It is preferred that, step 2, the concentration that ptfe emulsion is added in the mixture is 50%.
A kind of water treatment absorbent based on coal gasification lime-ash prepared by preparation method of the present invention.
Compared with prior art, the present invention has following beneficial technique effect：
The method of the invention polyacrylamide solution and ptfe emulsion and coal gasification lime-ash are according to a certain ratio
Mixing, wherein polyacrylamide and polytetrafluoroethylene (PTFE) each serve as the effect of modified and adhesive, pass through extrusion forming, drying
Water treatment absorbent is made；This method have raw material sources it is extensive, simple, it is efficient the characteristics of, while being the useless of coal gasification lime-ash
An easily approach is found in thing comprehensive utilization, and by simple technical process, coal gasification lime-ash is processed into engineering
The water treatment product of application value, reduces the expense that coal gasification lime-ash such as is stacked, filled at the disposal as solid waste, has
Preferable application value.
Adsorbent of the present invention not only has very strong adsorption capacity, while also there is preferable mechanical strength, can
To be directly used in water treatment field.
