Abstract
The present invention is the technological process of selecting iron oxide from sulfuric acid sludge, which is produced while producing acid. Sulfuric acid sludge from sulfuric acid boiling furnace is introduced to jigger directly or after properly cooling and separated in flowing water state, so that concentrated sulfuric acid sludge is obtained in settling tank. The present invention can utilize waste sludge fully and reduce environmental pollution.
Description
The present invention relates to from technology with the oxide of selected iron the sulfate slag of relieving haperacidity such as troilite, pyrite concentrate or non-ferro metals floatation tailings.
Sulfuric acid slag washing iron oxide generally adopts equipment such as shaking table, magnetic separator, and adopts corresponding technological process, and its separate unit is of poor benefits, and compound investment is big, iron content instability in the sulfate slag after selected, and the magnetic separation sulfur content is higher, is unfavorable for utilizing again.
The objective of the invention is to be intended to overcome above-mentioned shortcoming, a kind of selected technology with the sulfate slag that is produced in the relieving haperacidity processes such as troilite, pyrite concentrate or non-ferro metals floatation tailings of jigging machine that adopts is provided, this jigger sulfuric acid sludge selecting process can make the waste material waste residue be fully utilized, can be selected and adjust the grade of sulfate slag, can not cause environmental pollution, and small investment, cost is low, remarkable in economical benefits.
The object of the present invention is achieved like this:
The invention is characterized in: the sulfate slag that roasting is come out in the sulphuric acid fluidized bed roaster directly or is suitably feeding sorting under the flowing water state through jigging machine after the cooling, and natural subsidence obtains the smart slag of sulfuric acid in settling tank.
The flow process that the present invention includes open type and enclosed is respectively:
(A) open type: the sulfate slag that roasting is come out in the sulphuric acid fluidized bed roaster directly or is suitably feeding sorting under the flowing water state through jigging machine after the cooling, and natural subsidence obtains the smart slag of sulfuric acid in settling tank, the recrement of being taken out of by water obtains recrement through the settling tank natural subsidence more simultaneously, two sewage process water treatment station processing that settling tank comes out.
(B) enclosed: the sulfate slag that roasting is come out in the sulphuric acid fluidized bed roaster directly or is suitably feeding sorting under the flowing water state through jigging machine after the cooling, and natural subsidence obtains the smart slag of sulfuric acid in settling tank, simultaneously the recrement of being taken out of by water obtains recrement through the settling tank natural subsidence again, and the sewage that two settling tanks come out is handled the back by circulating slot and sent jigging machine back to by circulating pump and utilize.
The course of work of jigging machine operation of the present invention is: at the solid material of jigging machine screening online shop one deck and the close proportion of sulfate slag, regulate the bulging stroke of eliminating of jigging machine, open the water intaking valve at jigging machine middle part, treat the top water outlet, open top part water intaking valve again, charging simultaneously starts the motor of jigging machine, and according to circumstances regulates inflow and inlet amount.
Jigging machine used in the present invention is existing pyrite concentrate and cleaned coal washing common apparatus.
Sulfate slag iron content after the present invention is selected is at 50.0-65.0%.
The present invention designs ingenious, makes full use of the function of existing equipment jigging machine, has expanded the purposes field of jigging machine, the waste material waste residue is fully utilized, selected and adjust the grade of sulfate slag, can not cause environmental pollution, and small investment, cost is low, remarkable in economical benefits.
Provide accompanying drawing of the present invention below.

Below in conjunction with drawings and Examples, the invention will be further described.
The invention is characterized in: the sulfate slag that roasting is come out in the sulphuric acid fluidized bed roaster directly or is suitably feeding sorting under the flowing water state through jigging machine after the cooling, and natural subsidence obtains the smart slag of sulfuric acid in settling tank.
The flow process that the present invention includes open type and enclosed is respectively:
(A) open type: the sulfate slag that roasting is come out in the sulphuric acid fluidized bed roaster directly or is suitably feeding sorting under the flowing water state through jigging machine after the cooling, and natural subsidence obtains the smart slag of sulfuric acid in settling tank, the recrement of being taken out of by water obtains recrement through the settling tank natural subsidence more simultaneously, two sewage process water treatment station processing that settling tank comes out.
(B) enclosed: the sulfate slag that roasting is come out in the sulphuric acid fluidized bed roaster directly or is suitably feeding sorting under the flowing water state through jigging machine after the cooling, and natural subsidence obtains the smart slag of sulfuric acid in settling tank, simultaneously the recrement of being taken out of by water obtains recrement through the settling tank natural subsidence again, and the sewage that two settling tanks come out is handled the back by circulating slot and sent jigging machine back to by circulating pump and utilize.
The course of work of jigging machine operation of the present invention is: at the solid material of jigging machine screening online shop one deck and the close proportion of sulfate slag, as troilite; Regulate the bulging stroke of eliminating of jigging machine, open the water intaking valve at jigging machine middle part, treat the top water outlet, open top part water intaking valve again, charging simultaneously starts the motor of jigging machine, and according to circumstances regulates inflow and inlet amount.
Jigging machine used in the present invention is existing pyrite concentrate and cleaned coal washing common apparatus.As " bringing up tooth ripple jigging machine " that benficiation machinery factory in Xichang produces, model LTA-600 * 1200/2.
Sulfate slag iron content after the present invention is selected can be regulated arbitrarily in 50.0-65.0%.The present invention designs ingenious, makes full use of the function of existing equipment jigging machine, has expanded the purposes field of jigging machine, the waste material waste residue is fully utilized, selected and adjust the grade of sulfate slag, can not cause environmental pollution, and small investment, cost is low, remarkable in economical benefits.
