Description
Technical field
The present invention relates to a kind of for activated carbon of waste incineration dioxin in flue gas absorption and preparation method thereof, belong to suction
Enclosure material technical field.
Background technology
Bioxin (Dioxin), also known as dioxa glutinous rehmannia, are the very big liposoluble substances of a kind of colorless and odorless, toxicity, property
Highly stable, fusing point is higher, it is extremely difficult to be dissolved in water, be very easy to accumulate in vivo, harm to the human body is very big.Experiment shows
The toxicity of bioxin is about 130 times of extremely toxic substance cyanide, 900 times of arsenic, and it is lethal that very low concentrations will allow animal to occur
Effect.1986, in Taiwan Er Renxi and Feng Shanxi, since hardware dealer burns cable waste, the bioxin of generation was seriously dirty
Local environment has been contaminated, local common people people more than 2000 is caused dizzy fever phenomenon occur.
Increase with the development of economy with material consumption, the discharge capacity of house refuse increases year by year, and it is place directly to burn
The main method of house refuse is managed, treating capacity is big, speed is fast, floor space is small.It can be generated however, house refuse is directly burned
Bioxin, it is necessary to handle the bioxin in combustion refuse incineration flue gas, no it will cause serious secondary pollutions.Research
It was found that , bioxin pollutant is mainly generated through following three kinds of modes：1) plastic containing chlorines such as vinyl chloride are less than 800 DEG C in temperature
Under the conditions of burn, plastic containing chlorine incomplete combustion, easily generate bioxin synthesis precursor --- chlorobenzene, ultimately generate Er Evil
English；2) other containing chlorine, carbonaceous material such as paper, woodwork, swills etc. by copper, the metal ions such as cobalt catalytic action and
Directly generate bioxin；3) it is easily sent in the manufacturing process of Insecticides (tech) ＆ Herbicides (tech), timber preservative, defoliant, Polychlorinated biphenyls etc.
Life forms bioxin.
Activated carbon has huge specific surface area and unique aperture structure, is weight in the water body and air being widely used
The high-efficiency adsorbent of metal pollutant, organic pollution etc. and at present waste incineration enterprise are common to burn for removing rubbish
Burn the sorbing material of dioxin in flue gas.Research shows that the suction of the mesopore activated carbon Dui bioxin rich in aperture 2~5nm micropores
Attached effect is best.However, on the market the micropore size of more than 80% activated carbon product all concentrate on mostly less than 2nm or (and)
In the range of 5nm, micropore size be not it is too small be exactly too big, rubbish undesirable for the adsorption effect of bioxin molecule
Rubbish burn enterprise activated carbon choose and there are blind areas using upper also, depend on engineering experience unduly, often there are activated carbon mistakes
The problems such as degree waste He dioxin emissions are not up to standard.
Invention content
The purpose of the present invention is to provide a kind of activated carbon for the absorption of waste incineration dioxin in flue gas and its preparations
Method.

3) coal particle is put into carbonization-activation stove, 500~550 DEG C carbonize 3~5 hours, then are passed through vapor, and 850~950
DEG C activation 4~8 hours, then is cooled to 100~200 DEG C under the protection of inert gas, grinds, obtain for flue gas of refuse burning
The activated carbon of Zhong bioxin absorption.
The grain size of coal dust intermixture described in step 1) is 75~105 μm.
The mass ratio of anthracite, meager coal, weakly caking coal described in step 1) is 1：(1~6)：(6~17).

Catalyst described in step 2) is at least one of ferric nitrate, cobalt nitrate, nickel nitrate.
Inert gas described in step 3) is nitrogen.
The grain size of activated carbon described in step 3) is 45~75 μm.
The beneficial effects of the invention are as follows：
1) micropore size of existing activated carbon product have focused largely on less than 2nm or (and) more than 5nm in the range of, it is micro-
Hole aperture be not it is too small be exactly too big, absorption of activated carbon product of the micropore size less than 2nm to gas and liquid small molecular
Effect is pretty good, but poor for the adsorption effect of some polymer, organic bath and inorganic macromolecular, and micropore size is more than
The activated carbon product of 5nm only has adsorption effect to the macromolecular for reaching specified molecular weight, their absorption for bioxin molecule
Effect is undesirable, and the micropore size of the activated carbon for the absorption of waste incineration dioxin in flue gas of the invention is concentrated mainly on
It is not only good to the adsorption effect of small molecule between 2~5nm, but also to the absorption of polymer, organic bath and inorganic macromolecular
Effect is also fine, and the adsorption effect of especially Dui bioxin is splendid；
2) micropore size of the activated carbon for the absorption of waste incineration dioxin in flue gas of the invention is larger, as catalysis
Contribute to homodisperse (such as except formaldehyde activity charcoal needs loaded potassium permanganate) of catalyst during agent carrier；
3) process for preparing activated carbon for the absorption of waste incineration dioxin in flue gas of the invention is simple, at low cost, energy
It consumes low, can be widely used for the absorption of garbage incinerating tail gas Zhong bioxin, also act as catalyst carrier and other sorbing materials.
