Description

Aluminum phosphide residue processing apparatus

Technical Field

The utility model belongs to the field of chemical equipment, and particularly relates to an aluminum phosphide residue treatment device.

Background

The pure aluminum phosphide product is white crystal and has high pesticidal efficiency and wide application. The content of aluminium phosphide for fumigating granary is 56.0-58.5%. Only 3-7 tablets are needed for fumigating each ton of grain, and only 1-2 tablets are needed for each cubic meter. The toxicity of aluminum phosphide is mainly that aluminum phosphide gas is rapidly decomposed when meeting water and acid, and releases hydrogen phosphide gas which is rapidly absorbed and has severe toxicity. The mixture with ammonium carbamate can be used as a pesticide and also for welding. The aluminum phosphide residues are used as chemical reaction products of aluminum phosphide, and 3% -5% of phosphine components in the aluminum phosphide residues cannot be completely volatilized, decomposed and utilized due to the influences of a plurality of factors such as temperature and humidity, fumigation environment, fumigation time, medicament structure of the aluminum phosphide and the like, so that the environment and human health are polluted and injured due to improper disposal. The current methods for treating the residue include the following methods: A. deep burying method: after fumigating and gas dissipation, the aluminum phosphide residues are collected and immediately transported to a remote place 50m away from a water source, and the pit is dug and buried deeply. The method is the main aluminum phosphide residue treatment method at present. But no anti-seepage measures are taken, so that the safety of the buried residues cannot be ensured. If the residue meets rainwater, phosphine gas can be generated, and can be accumulated when the phosphine gas cannot be discharged, so that people and livestock near the residue landfill site can be poisoned or fire and smoke can be generated in serious cases. The method is not scientific and cannot thoroughly solve the harm of the aluminum phosphide residues.

B. The soaking method comprises the following steps: the aluminum phosphide residues are soaked in washing powder water, acid-base solution and the like to promote the unreacted aluminum phosphide in the aluminum phosphide residues to react completely. The method can thoroughly remove unreacted aluminum phosphide in the residue, and thoroughly solve the potential safety hazard. However, in actual practice, it has been found that a large amount of phosphine is generated by the immersion method, and if the phosphine cannot be treated, the surrounding air is polluted, and accidents such as smoking and ignition may occur in a serious case.

C. The burning method comprises the following steps: the aluminum phosphide residue is incinerated at the temperature of over 1100 ℃ for reduction and harmless treatment, and the incinerated residual ash can be used as an auxiliary material for cement production. The method needs to build a special incinerator, and has the disadvantages of high cost, inevitable potential safety hazard during transportation of the aluminum phosphide residues and high operation difficulty due to the fact that the amount of aluminum phosphide residues generated in each area is small.

Disclosure of Invention

In order to treat the aluminum phosphide residue more safely and effectively and scientifically realize the non-toxic and harmless treatment of the residue, the inventor of the application prepares the water filtering type aluminum phosphide residue water decomposition cylinder, and effectively ensures the safety of the treatment of the aluminum phosphide residue.

The utility model aims to realize the purpose, which comprises a decomposition cylinder, wherein the top of the decomposition cylinder is provided with an isolation cover, and a high-pressure water gun is arranged on the isolation cover.

Compared with the prior art, the utility model has the following advantages and effects:

adopt high-pressure squirt stirring to dilute and replace traditional stick and the stirring of electric hammer, electric hammer puddler that charges and dilute. The setting of decomposition jar and isolation lid for the treatment personnel and mixed liquid surface contactless have increased factor of safety, also make the water that flows constantly pour into the in-process that decomposes the jar through the high-pressure squirt and constantly stir and dilute the aluminium phosphide that is not decomposed completely in the residue, make the stirring more even, dilute more completely, effectively ensured the processing safety of aluminium phosphide residue. Phosphine gas generated in the decomposition process is collected by the phosphine filtering and absorbing device and then treated, so that the pollution to the external environment caused by direct discharge to the air is avoided.
