Abstract

The cleaning agent for smoke produced by refuse incineration comprises water and is characterized by that said cleaning agent comprises attapulgite powder, and is a suspension slurry formed from attaplugite powder and water in which the attaplugite powder content is 10-20% and the rest is water. Said invention is stable in cleaning capacity, can integrate the washing action and adsorption actino into one body so as to reduce its equipment and cost.

Description

Garbage-incineration smoke purifying agent and purifier
Technical field:
The invention relates to the purification of burnt gas, particularly about the purified treatment of flue gas of refuse burning.
Background technology:
Traditional waste disposal method is landfill or makes farmers''s compost.But along with the global urban development, population is concentrated to cities and towns day by day, and the quantity of house refuse grows with each passing day, the land used of refuse landfill and dung yard also swashs acute the rising, the land resource of a large amount of preciousnesses of not only having eaten, and be pollution sources, environment is on every side produced many negative effects.Come disposal of refuse with burning method, can save land used, so showing soil day under the situation of atrophy now, particularly people pay attention to, and have become the preferred option of most developed countries disposal of refuse.But during waste incineration, the flue gas that it produced is still a big problem to the pollution of environment.Since the raising of people's living standard, the improvement of material conditions, and the composition of house refuse is also complicated day by day.Therefore during waste incineration, the flue gas of its generation not only stench is unpleasant, and contains much as the chemical substance of the toxic effect of dioxin and so on and the heavy metal dust of harmful health.For the flue gas that prevents toxic effect causes secondary pollution, must carry out purified treatment to it, to reach the regulation of relevant criterion.At present all adopt water and active carbon, utilize the suction-operated of the cleaning function and the active carbon of water, the peculiar smell in the flue gas, chemical substance and heavy metal are removed as the cleanser of flue gas of refuse burning.Employed equipment is water scrubber and the adsorption tower that is filled with active carbon.Flue gas after the washing enters from the adsorption tower bottom, purifies the back and is discharged by the top.But active carbon can not be regenerated, and its suction-operated is irreversible, and with the prolongation of its service time, suction-operated descends gradually, loses adsorption capacity at last, must periodic replacement.And the costing an arm and a leg of active carbon, the expense that gas cleaning is handled rises.For this reason, active carbon is not the desirable cleanser that flue gas is handled.In addition, water needs otherwise processed to recycle.
Summary of the invention:
The object of the present invention is to provide a kind of garbage-incineration smoke purifying agent and purifier, the detergent power that solves cleanser is stable, and makes washing and suction-operated unification, minimizing equipment and the technical problem that reduces expense.
The technical scheme that the present invention solves the problems of the technologies described above is as follows:
A kind of garbage-incineration smoke purifying agent comprises water, it is characterized in that: this cleanser includes attapulgite (attapulgite, formal name used at school attapulgite) powder, is the suspension of water and attapulgite powder, and its weight percent consists of:
Attapulgite powder 10-20%
Water surplus
Above-mentioned garbage-incineration smoke purifying agent is characterized in that: the fineness of this attapulgite powder is not less than 300 orders.
Above-mentioned garbage-incineration smoke purifying agent is characterized in that: the pH value of this suspension is 6-8.
A kind of garbage-incineration smoke purifying device is characterized in that: this purifier comprises sedimentation basin, pump, spray head, sieve-plate tower and pipeline; This spray head is arranged on sieve-plate tower top, and links to each other with the delivery outlet of pump with pipeline; The pipeline that is connected this pump input port stretches into sedimentation basin; The sieve-plate tower bottom links to each other with sedimentation basin by pipeline.
Above-mentioned garbage-incineration smoke purifying device is characterized in that: be provided with cyclone separator, this cyclone inlet links to each other with the sieve-plate tower exhanst gas outlet.
Advantage of the present invention is as follows:
1. absorption and washing unite two into one, and have reduced facility, have reduced equipment cost.
2. attapulgite (attapulgite, formal name used at school attapulgite) is a kind of natural fibrous clay mineral, and domestic have suitable reserves, is the secondary product of shell or timber unlike active carbon, therefore not limited by raw material, and cheap.Make operating cost of the present invention be lower than traditional purified treatment cost.
3. the specific area of attapulgite is 400-500M greater than active carbon 2/ gram is so its absorption property is much better than active carbon.The flue gas of getting rid of be up to state standards fully regulation, particularly stink are almost become extinct.
4. flue gas of refuse burning is acid, and attapulgite is alkaline, just in time realizes neutralization, and needn't add nertralizer in addition.
5. cleanser can be separated out sediment in sedimentation basin after repeatedly recycling, and sediment can be removed, and adds an amount of new attapulgite powder again and can make cleanser keep detergent power constantly to recycle forever.
Description of drawings:
Fig. 1 is a purifier structural representation of the present invention.
The specific embodiment:
Cleanser of the present invention is by the powder of attapulgite and the suspension of water.In addition attapulgite is ground into 300 orders or thinner powder, is mixed into cleanser with water again.The percentage by weight of attapulgite is 10-20% in this cleanser, and all the other are water.Because it is acid that the rubbish flue gas is, the pH value of cleanser should be adjusted at 6-8 and be advisable.
Comprise sedimentation basin 5, pump 6, spray thrower 7 and sieve-plate tower 3 referring to Fig. 1 purifier of the present invention.Be provided with several layers sieve plate 31 in the sieve-plate tower 3, its bottom is connected with sedimentation basin 5 by pipeline 4 piping 4 that is connected with sedimentation basin 5.During use, cleanser of the present invention is inserted in the sedimentation basin 5.Start pump 6 runnings, then cleanser is pressed to spray thrower 7 and is sprayed in the sieve-plate tower 3 through pipeline 4 in the sedimentation basin 5, and through after the stopping of multilayer sieve plate 31, is in the sieve-plate tower 3 of rain shape.Cleanser just can fully be removed in sieve-plate tower 3 from the incinerator smoke that smoke inlet 7 enters like this, carries out washing and absorption.At last, the flue gas that is cleaned is got rid of by the sieve-plate tower top; Cleanser then accumulates in sieve-plate tower 3 bottoms, passes back into sedimentation basin 5 through pipeline 4 and drops into once more and recycle.Owing to when flue gas after being purified is discharged from sieve-plate tower top, carry a spot of cleanser inevitably.For not wasting cleanser, can be provided with cyclone separator 2, the inlet of this cyclone separator 2 is connected with the exhanst gas outlet of sieve-plate tower 3 tops, and its bottom is communicated with sedimentation basin 5 lines by pipeline 4.The purification flue gas that comes out from sieve-plate tower 3 is when cyclone separator 2 like this, and wherein the cleanser of being carried secretly is separated by centrifugal force, and accumulates in the bottom of cyclone separator 2, flows back to sedimentation basin through pipeline 4.The then moving fume emission mouth 1 of dry purification flue gas is got rid of.
