Abstract
The invention discloses a detoxification treatment method of trace nickel carbonyl and iron carbonyl. The detoxification treatment method is characterized by comprising the following steps of: generating ozonization gas via an ozone generator, wherein the content of ozone is 100-120mg/L; mixing the ozonization gas with recycled carbon monoxide gas containing trace nickel carbonyl and iron carbonyl in a flow ratio of 1:180-200, wherein the nickel carbonyl and the iron carbonyl react with ozone; and recycling the recycled carbon monoxide gas in a next purification process.
Description
Technical field
The present invention relates generally to a kind of detoxifcation processing method, relates in particular to the detoxifcation processing method of a kind of micro-carbonyl nickel, carbonyl iron.
Background technology
In the life of carbonyl nickel powder, carbonyl iron dust, carbonyl nickel, carbonyl iron decompose the back and produce CO gas, inevitably contain undecomposed carbonyl nickel, carbonyl iron in the gas, because gas need adsorb recycle and reuse by transformation, to remove impurity wherein, carry out duplication of production.When recycling, carbonyl nickel, carbonyl iron impurity can influence the activity of adsorbent in the transformation absorption, adsorbent is poisoned, ineffective, therefore before recycling, to remove CO gas micro-carbonyl nickel, carbonyl iron in the CO gas as much as possible.
Summary of the invention
The object of the invention is exactly in order to remedy the defective of prior art, the detoxifcation processing method of a kind of micro-carbonyl nickel, carbonyl iron to be provided.
The present invention is achieved by the following technical solutions:
The detoxifcation processing method of a kind of micro-carbonyl nickel, carbonyl iron may further comprise the steps:
Produce ozonisation gas by ozone generator, wherein ozone content is 100-120mg/L, ozonisation gas is that 1:180-200 ratio mixes with the recovery CO gas that contains micro-carbonyl nickel, carbonyl iron in flow-rate ratio, carbonyl nickel wherein and carbonyl iron and ozone react, generate nickel oxide and iron oxide, reaction equation is as follows:
Ni(CO)
4 ＋ 4O＝NiO＋4CO
2
2Fe(CO)
5 ＋13O＝Fe
