Abstract
An industrial sludge combustion processing method includes the following steps of firstly, sufficiently mixing industrial sludge and glue residues to obtain a mixture; secondly, drying the mixture at 200-250 DEG C by means of a heat conduction carrier paddle type dryer so that the water content of the mixture can be 25-40%, and conducting hot forming; thirdly, laying the formed mixture on the bottom layer of a chain row furnace, laying a coke layer or a semi coke layer on the mixture, and conducting combustion at a temperature higher than 950 DEG C till solid furnace slag of which harmful components in industrial sludge are completely combusted into non-toxic extraction is obtained. The solid furnace slag of which harmful components in industrial sludge are completely combusted into non-toxic extraction is obtained finally, the solid furnace slag can be used as a building material, and success is achieved in commerce.
Description
Technical field
The present invention relates to a kind of industrial sludge burn processing method.
Background technology
With the quickening of the industrialized development of China and urbanization process, the raising for the treatment of rate of domestic sewage, create big
Amount industrial sludge, industrial sludge is the pollutant that a kind of property is complicated, pollutant load is high, Potential environmental risk is huge, is high
The solid material of the liquid of moisture content, containing the heavy metal poisonous and harmful substance such as substantial amounts of pathogen, parasitic ovum and chromium, hydrargyrum.Mud
Have a strong impact on the productive life of people, caused severe contamination to environment, industrial sludge process problem has become as have been worked as
One big the difficult problem of environmental protection of modern society urgent need to resolve.
With respect to landfill and the compost treatment of mud, burning method has volume reduction, weight-loss ratio height, and processing speed is fast, innoxious
More thoroughly, the advantages of reusing of energy source, it is one of effective practical technique of disposing sludge.But, in the highest firepower of burning
The temperature of the heart only has 850 DEG C, due to industrial sludge moisture content high (the industrial sludge moisture content after process also up to more than 80%) with
And wherein as difficult in copper, nickel, zinc, aluminum etc. the incendive composition that contains is it is impossible to maintain the self-holding of combustion process to carry out, burned
Cheng Zhonghui produces serious pollution.
Content of the invention
It is an object of the invention to provide a kind of industrial sludge burn processing method.
For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of industrial sludge burn processing method, including with
Lower step:
The first step: mixing
Industrial sludge is sufficiently mixed with combustible, mixture is obtained with this；
Second step: be dried
Using heat conduction carrier paddle-dryer, described mixture is dried at 200 ~ 250 DEG C, makes the aqueous of mixture
Rate is 25 ~ 40%；Molding while hot；
3rd step: burning
Mixture after molding is layed in the bottom of chain grate furnace, and side's laying coke layer or semi-coke layer on the mixture, carry out
Burning, ignition temperature is higher than 950 DEG C, until the harmful components in industrial sludge all sinter the solid stove of avirulence leaching into
Slag.
In such scheme, using biaxial rneader, industrial sludge is mixed with combustible.
In such scheme, described combustible is glue residue.Or, described combustible is coal dust.
In such scheme, after described drying, the moisture content of bar-shaped mixture is 30 ~ 40%.
In such scheme, the mixture after described molding while hot is bar-shaped mixture.
Preferably, the burning of described 3rd step is: the mixture after molding is layed in the bottom of chain grate furnace, and in mixing
Above thing, laying coke layer or semi-coke layer, are burnt, and first, ignition temperature controls in the range of 250 ~ 300 DEG C, keeps combustion
Burn at least 30 minutes, so that Organic substance in industrial sludge is separated out and burn totally；Then, ignition temperature is higher than 950 DEG C,
Until the harmful components in industrial sludge all sinter the solid slag of avirulence leaching into.
Preferably, it is additionally provided with baking step between the burning of the drying of described second step and the 3rd step, make mixed after molding
The moisture content of compound is 30 ~ 35%.
Preferably, the mixed volume ratio of described industrial sludge and combustible is (20 ~ 30): 100.
Because technique scheme is used, the present invention compared with prior art has the advantage that
1. the present invention is mixed into combustible (such as glue residue) in industrial sludge, because the density of glue residue is little and hygroscopic, in mixing
During, glue residue absorbs the part moisture in industrial sludge, and glue residue is mixed in industrial sludge, is equivalent to shape in industrial sludge
Many little spaces are become, more preferably, after being dried, its moisture content can reach 25 ~ 40%, simultaneously as glue residue is good to drying effect
Combustibility, substantially increases the combustion rate of industrial sludge, has finally given the harmful components in industrial sludge and has all sintered into no
The solid slag that toxicity leaches, these solid slag can serve as construction material, have been commercially available success；
2. the mixture of industrial sludge and glue residue is made bar-shaped, and laying coke layer or orchid on bar-shaped mixture by the present invention
Layer of charcoal is it is ensured that bar-shaped mixture can fully burn, and makes ignition temperature be higher than 950 DEG C；
3. the burning of the present invention divides two sections to carry out, and at 250 ~ 300 DEG C, this stage mainly makes work to the temperature control of first paragraph
Organic substance in industry mud separates out burning, is beneficial to the burning of second stage inorganic matters and heavy metal, the temperature control of second segment
More than 1000 DEG C, ensure that with this harmful substance in industrial sludge can all sinter the slag of avirulence leaching into, will weigh
Metal changes into metal-oxide, then using its recycling as building materials Feedstock treating, great environment protection significance.
Specific embodiment
With reference to embodiment, the invention will be further described:
Embodiment one:
A kind of industrial sludge burn processing method, comprises the following steps:
The first step: mixing
Industrial sludge is sufficiently mixed with glue residue, the mixed volume ratio of industrial sludge and glue residue is 30:100, is mixed with this
Compound；
Second step: be dried
Using heat conduction carrier paddle-dryer, described mixture is dried at 200 ~ 250 DEG C, makes the aqueous of mixture
Rate is 30%；Molding while hot, obtains bar-shaped mixture；
3rd step: burning
Mixture after molding is layed in the bottom of chain grate furnace, and side's laying coke layer or semi-coke layer on the mixture, carry out
Burning, first, ignition temperature controls in the range of 250 ~ 300 DEG C, keeps burning at least 30 minutes, makes industrial sludge with this
In Organic substance separate out and burning totally；Then, ignition temperature is higher than 950 DEG C, until the harmful components in industrial sludge are whole
