Description
Technical field
The utility model relates to a kind of aluminium phosphide tablet fumigant residue treatment device, belongs to pollution prevention technique field.
Background technology
Aluminium phosphide is that boats and ships are fumigated important fumigant in process with boat, and its activeconstituents is that aluminium phosphide reacts the phosphuret-(t)ed hydrogen generating with water.Phosphuret-(t)ed hydrogen is the fumigant insect killing gas of a kind of severe toxicity, efficient, broad spectrum.This gas is heavier than air, and has the taste of similar smelly fish.Sucking phosphuret-(t)ed hydrogen can impact heart, respiratory system, kidney, stomach, neural system and liver.Lower concentration sucks, and can cause shedding tears, stimulates lung, breathes hard, cough, lung be long-pending.Aluminium phosphide, in stifling use procedure, still contains the aluminium phosphide that different ratios do not resolve residual in its reacting final product (residue) and the aluminium phosphide medicament scrapped.The gaseous phosphine that aluminium phosphide residue produces, severe toxicity, easily causes person poultry poisoning; After aluminium hydroxide that simultaneously residue produces is buried, soil is caused to the permanent damage of unrepairable.
For the processing mode one of the aluminium phosphide medicament residue routine after stifling be dig pit buried, the 2nd, pour water drain.But these simple ways all have problems in practice: the one, and the aluminium phosphide residue of digging pit buried, meeting wet or sleet sky, can volatilize phosphine gas, to environment with people, animal all can pollute and dangerous; The 2nd, contaminated land area is larger.These measures inevitably bring problem of environmental pollution, cause the death of personnel, bird and livestock, serious threat people's the security of the lives and property.The soil that buries aluminium phosphide can not be used Planting Crops substantially, takies surface area 0.5m to dig to bury at every turn
2calculate, the quantity in annexation soil is surprising.Digging pit in buried process, because repeating to dig to bury, land for building anxiety cause the residue of burying more and more shallow apart from earth's surface, human settlement has been caused to potential safety hazard.Meanwhile, the aluminium hydroxide after the residue of burying decomposes causes the pollution of unrepairable, serious threat environmental safety to soil.
Once there is multiple treatment process to occur.Such as the treatment agent that CN03123584 adopts catalyzer, acid and oxygenant to form, to aluminium phosphide residue oxide treatment, catalyzer is copper sulfate, and oxygenant is potassium permanganate.Processing cost is high, and the waste residue and the waste liquid that after processing, form have secondary pollution problem; CN201210088920 discloses a kind of method, and device is compact, adopts potassium permanganate as oxygenant, only phosphine gas is had to reasonable treatment effect, has equally waste residue and waste liquid secondary pollution problem.
Prior art is processed aluminium phosphide residue and is had many problems, mainly contain three aspects, the one, the atmosphere pollution of the phosphuret-(t)ed hydrogen discharging after hydrolysis, the 2nd, the waste residue (aluminium hydroxide etc.) forming after processing produces secondary pollution, and the 3rd, waste liquid after treatment can not qualified discharge.
For by the thorough harmless treatment of aluminium phosphide tablet residue, need to seek new technological method and address this problem.
Utility model content
The utility model processes for prior art the practical problems that aluminium phosphide residue exists, and provides a kind of aluminium phosphide tablet fumigant residue treatment device, by the existing problem of the integrated solution of absorb-polymerization of cyclic oxidation.
The technical solution of the utility model is as follows:
A kind of aluminium phosphide tablet fumigant residue treatment device, is characterized in that, comprise polymerization reactor, absorption tower, storage tank and separator, described polymerization reactor is connected with described absorption tower by air shooter; In described storage tank, deposit absorption liquid and be connected with described absorption tower; Described polymerization reactor bottom is connected with described separator.
Further, described polymerization reactor is provided with liquid charging opening and solid feed inlet, described liquid charging opening is used for adding water or hydrochloric acid, so that aluminium phosphide tablet fumigant residue hydrolysis in polymerization reactor, described solid feed inlet is used for adding aluminium phosphide tablet fumigant residue.
Further, described absorption tower adopts counter-current operation, and described absorption liquid is sprayed by the tower top on described absorption tower.
Further; supplementary protection gas distribution on the air shooter of described polymerization reactor; the air being used in blow device before hydrolysis; the phosphine gas that hydrolytic process is used for carrying generation enters absorption tower; stablize aluminium phosphide tablet fumigant residue treatment effect, avoid occurring phosphine gas spontaneous combustion.
Further, described shielding gas comprises argon gas, helium and nitrogen.
Further, described phosphine gas is entered by the tower bottom on described absorption tower.
Further, between described storage tank and described absorption tower, be also provided with volume pump.
Further, the sodium chlorite solution that described absorption liquid is 25%-75%.
Further, described separator is filtered auxiliary material residue and polymerisate-liquid aluminium polychloride is separated by filter plate.
Further, the top on described absorption tower arranges liquid distributor, to improve absorption liquid spraying effect; The bottom on described absorption tower arranges gas distributor, to improve gas-liquid mass transfer effect.
The advantage of the utility model device is the thorough harmless treatment of aluminium phosphide tablet fumigant residue.Specifically, the effect of the technical program is that aluminium phosphide tablet fumigant residue is resolved into phosphine gas and aluminium hydroxide solid, and wherein, phosphine gas is carried and entered absorption tower by shielding gas, is oxidized to free of contamination phosphate solution, can be used as agriculture fertilizer; Aluminium hydroxide solid further with hydrochloric acid reaction, form polymerize aluminum chloride (basicity is 35%-40%), be a kind of good water conditioner, can directly sell as product; Isolating waste residue is harmless talcum powder or magnesium stearate, can directly enter soil.
