Abstract
The invention belongs to a harmless treatment technology for aluminum phosphide fumigation residues, wherein the technology is applicable for harmless treatment of aluminum phosphide fumigation residues in the industry. According to the harmless treatment method for aluminum phosphide fumigation residues, aluminum phosphide fumigation powder residues and excess water are mixed in a closed container; a protection gas is introduced, and a stirring treatment is performed under a certain state, wherein the state is assurance of no air; the generated PH3 gas and the protection gas enter a tail gas absorption device; an oxidizing agent spraying treatment is performed two times to carry out a tail gas absorption treatment, wherein a slight negative pressure state inside a spraying tower is ensured during the spraying process, and the PH3 gas is subjected to a completely harmless treatment; and the treated residues are adopted as a cement production raw material to be conveyed to a cement plant to be comprehensively utilized. The method of the present invention has the following advantages that: the aluminum phosphide fumigation residues are subjected to the harmless treatment while the risk coefficient of the operation is reduced, and the PH3 gas produced in the process is further subjected to the harmless treatment at the same time so as to avoid secondary pollution generation, and completely solve the pollution problem of the aluminum phosphide fumigation residues.
Description
Technical field
The present invention relates to the method for a kind of aluminum phosphide fumigation residue harmless treatment.
Background technology
Aluminum phosphate is present domestic and international widely used fumigant; Do not decompose fully and utilize and contain aluminum phosphate 3% or more in its residue after stifling, aluminum phosphate runs into water in air branch production phosphine gas, and hydrogen phosphide belongs to extremely toxic substance; So it is very important that science is handled the aluminum phosphate residue.Two kinds of forms are generally taked in the processing of aluminum phosphate residue at present: the one, handle through chemical treatments; The 2nd, look for place far away, dried up source to dig pit buried.This dual mode all can't be avoided the volatilization of residual hydrogen phosphide fully, and phosphine gas has inflammable and explosive characteristic, in processing procedure, has greatly potential safety hazard, deals with improperly and can cause combustion explosion, causes second environmental pollution simultaneously.
Summary of the invention
The objective of the invention is to overcome above-mentioned not enough problem, the method for a kind of aluminum phosphide fumigation residue harmless treatment is provided, the aluminum phosphate residue is carried out nontoxic, harmless treatment, accomplish safety, environmental protection, thoroughly solved the pollution problem of aluminum phosphide fumigation residue.
The present invention for realizing the technical scheme that above-mentioned purpose adopted is: in closed container with aluminum phosphide fumigation powder residue with after excessive water mixes, the feeding protective gas guarantees under air-free state, to stir the PH of generation
3Gas gets into the tail gas absorption treating device together with protective gas, absorbs through twice oxidant spray tail gas and handles, and the spray process guarantees that in the spray column be micro-vacuum state, PH
3Gas harmless treatment fully; Handle the back residue and advance the cement plant comprehensive utilization as cement producting material.
The method of described aluminum phosphide fumigation residue harmless treatment, wherein said protective gas is: nitrogen, carbon dioxide.
The method of described aluminum phosphide fumigation residue harmless treatment, wherein said same PH
3The oxidant of reaction is: copper sulphate, clorox or hydrogen peroxide solution etc.
The copper sulphate that said oxidant employing mass percentage concentration is 5%-20%, the mass percentage concentration of effective chlorine are that clorox or the mass percentage concentration of 5%-13% is the hydrogen peroxide solution of 5%-40%.
It is that the mass percentage concentration of 20% copper sulphate, effective chlorine is that 10% clorox or mass percentage concentration are 30% hydrogen peroxide solution that said oxidant adopts mass percentage concentration.
The method of described aluminum phosphide fumigation residue harmless treatment, wherein said tail gas are absorbed as twice spray of two kinds of identical or different oxidants for twice, and wherein spray process maintenance spray column is a negative pressure state.
Described spray column micro-vacuum state, wherein said little range of negative pressure be controlled at 0MPa---0.02MPa.
Described spray column micro-vacuum state, the optimal value of wherein said little negative pressure control is-0.005MPa.
