In one aspect of the invention, the present invention proposes a kind of method for handling pyrolysis rubbish carbon residue, according to the present invention
Embodiment, with reference to Fig. 1, this method includes：
S100：Pyrolysis rubbish carbon residue, coal, quick lime, humic acid and water are mixed
In the step, pyrolysis rubbish carbon residue, coal, quick lime, humic acid and water are mixed, to obtain mixture
Material, wherein, the mass ratio of pyrolysis rubbish carbon residue and coal is (0.5~1)：(0.5~0.8).Inventor has found, by that will be pyrolyzed rubbish
Rubbish carbon residue part replaces gasification carbon source coal, turns waste into wealth, realizes the comprehensive utilization of rubbish, saved carbon resource；And inciting somebody to action
When pyrolysis rubbish carbon residue is mixed with coal, using quick lime and humic acid as compound binding agent, easy to operate, bond effect is good,
The cold strength and heat endurance of dry pelletizing can be improved so that dry pelletizing can meet gasification production enter stove requirement and production
During calorific intensity requirement, while the use of compound binding agent solves pyrolysis, rubbish carbon residue ash fusion point is low, easy slagging and viscous
The problem of wall.Specifically, humic acid binder is a kind of water-soluble caking property, have affine well to coal and pyrolysis rubbish carbon residue
Power, the surface of coal can be soaked well, coal and pyrolysis rubbish carbon residue can well be sticked together during shaping, be had mixing pelletizing
There is certain initial strength, and humic acid can constantly be condensed into gel after the drying, shrink solidification, can so make to dry pelletizing tool

Art personnel can be selected according to actual needs, according to the specific embodiment of the present invention, calcium oxide content in quick lime
82wt% can be not less than.Inventor has found, when the content of calcium oxide is controlled in more than 82wt%, it is ensured that the ash of type ball
Fusing point is higher, while effectively can solidify to sulphur in type ball, realizes the effect of solid sulphur, and is advantageously implemented follow-up gasification dress
Put deslagging smooth, and if calcium oxide content is too low, even below 82wt%, excessive impurity is not only introduced, while excessive nothing
Imitate into branch and cause energy consumption increase of subsequently gasifying, economic effect is poor.
According to still another embodiment of the invention, the time of mixed processing is not particularly restricted, those skilled in the art
Member can be selected according to actual needs, and according to the specific embodiment of the present invention, the time of mixed processing can be 8-
15min.Thus, you can make it that pyrolysis rubbish carbon residue is well mixed with coal, quick lime, humic acid and water and can significantly be saved
Energy consumption, improves the ageing of whole technique.
S200：Mixed material is subjected to forming processes
In the step, mixed material is subjected to forming processes, to obtain mixing pelletizing.Thus, it can further improve heat
The contact area of rubbish carbon residue and coal, quick lime and humic acid is solved, and then improves the quality of gained mixing pelletizing.
According to one embodiment of present invention, the pressure of forming processes is not particularly restricted, those skilled in the art
It can be selected according to actual needs, according to the specific embodiment of the present invention, the pressure of forming processes can be 18-
25MPa.Inventor has found that can be significantly better than other using the pressure of forming processes proposed by the present invention improves mixing pelletizing
Balling ratio, while saving energy consumption.
S300：Processing is dried in mixing pelletizing
In the step, processing is dried in mixing pelletizing, to obtain drying pelletizing and vapor.Inventor's discovery,
Mix pelletizing has certain initial strength in the presence of humic acid binder, and after drying process, humic acid is constantly concentrated
Into gel, solidification is shunk, so that drying pelletizing has higher mechanical strength.
According to one embodiment of present invention, the temperature of drying process is not particularly restricted, those skilled in the art
It can be selected according to actual needs, according to the specific embodiment of the present invention, the temperature of drying process can be 100-
150 degrees Celsius.Inventor has found that processing is dried in this temperature range can be significantly better than other raising drying process
Efficiency, and the quality that gained dries pelletizing is improved, while saving the energy consumption of whole technique.
S400：The gentle agent of pelletizing will be dried and carry out gasification process
In the step, the gentle agent of pelletizing will be dried and carry out gasification process, to obtain coal gas and lime-ash, and by step
The vapor that S300 is obtained is used as gasifying agent.
According to one embodiment of present invention, the temperature of gasification process is not particularly restricted, those skilled in the art
It can be selected according to actual needs, according to the specific embodiment of the present invention, the temperature of gasification process can be 1000
~1200 degrees Celsius.
According to still a further embodiment, the particular type of gasifying agent is not particularly restricted, the technology of this area
Personnel can be selected according to actual needs, according to the present invention a specific embodiment, gasifying agent can include air and
At least one of vapor, and above-mentioned vapor comes from baking step.Thus, it can realize to pyrolysis rubbish carbon residue and coal
The cost of gasification process is significantly saved while gasification process.
The method of processing pyrolysis rubbish carbon residue according to embodiments of the present invention, by the way that rubbish carbon residue will be pyrolyzed with coal through mixed
Close, shaping, drying, gasify to produce coal gas, overcome that pyrolysis rubbish carbon residue ash content is high, ash fusion point is low is difficult to what is continued with
Problem；And when pyrolysis rubbish carbon residue is mixed with coal, compound binding agent, operation letter are used as using quick lime and humic acid
Just, bond effect is good, can improve the cold strength and heat endurance of dry pelletizing so that gasification production can be met by drying pelletizing
Enter the calorific intensity requirement in stove requirement and production process, while the use of compound binding agent solves pyrolysis rubbish carbon residue ash fusion point
The problem of low, easy slagging and viscous wall；Simultaneously water can be realized using the vapor obtained by drying course as the gasifying agent of gasification
The comprehensive utilization of resource, saving water resource.Thus, this method be pyrolyzed rubbish carbon residue part replace gasification carbon source coal, change give up into
Treasured, realizes the comprehensive utilization of rubbish, has saved carbon resource, and the technique is simple, easily operated, resource utilization is high.
