Abstract
A kind of method of producing Tai-Ace S 150 with coal gangue is carried out roasting with coal gangue, is ground into powdery, is 1 to 2.5 by the vitriol oil than colliery powder, and diluting concentrated sulfuric acid becomes the diluted acid of 16-18Be to add in the colliery powder, at 120-140 ℃, and 2-3kg/cm
2Reaction is 1.5-2 hour under the condition, removes slag through precipitation, and quality product meets the rough secondary standard requirement of HG1-32-77, and especially essentially no free acid and arsenic exist in the product.
Description
The invention belongs to a kind of production method of Tai-Ace S 150, is the method for producing Tai-Ace S 150 with coal gangue.
The production method of known Tai-Ace S 150 generally is to be raw material with bauxitic clay, and its resource and energy consumption are all big, needs a large amount of fat coals during roasting, compares the production cost height with the depleted coal gangue.Waste residue is handled difficulty.
The purpose of this invention is to provide a kind of is the method for raw material production Tai-Ace S 150 with the coal gangue.
For achieving the above object, coal gangue is being carried out roasting more than 1200 ℃, remove organic substance, pulverize after aluminum oxide in the coal gangue is fully activated, fineness is a 100-120 purpose screen underflow, the colliery powder after the pulverizing, is 1 to 2.5 by the vitriol oil than colliery powder, diluting concentrated sulfuric acid becomes the dilute sulphuric acid of 16-18Be ' to add in the colliery powder, under 120-140 ℃ of temperature, and 2.5-3Kg/cm
2Pressure reacted 1.5-2 hour down, and reaction solution precipitates and removes slag, and gets its clear liquid to neutralize at normal temperatures with bauxitic clay, regulate PH in the 3-4 scope, and then the precipitation remove slag, with the clear liquid evaporation concentration to 50-55Be ' cool off, crystallization, promptly get industrial aluminum sulphate.
Advantage of the present invention and positively effect are: coal gangue is the discarded thing in colliery, and pile up like a mountain in each mining area, appropriation of land, and contaminate environment becomes society's one big public hazards.According to assay, contain 20-35%(weight % in the various coal gangues) aluminum oxide, can process the Tai-Ace S 150 product, contain a large amount of silicon-dioxide and other element in the waste residue after the processing, can process lagging material, material of construction such as non-burning brick or hollow brick are if adopt waste reside comprehensive utilization, waste water recycles, and then can eliminate environmental pollution.Because the coal gangue naturality is strong,, do not need the coal roasting, so the present invention has remarkable economic efficiency and social benefit except that lighting a fire with the fuel.The present invention's grasp simple to operate, easy, be specially adapted to township and village enterprises and use.Its quality product meets the rough secondary standard requirement of HG1-32-77, does not especially have free acid and arsenic in the product substantially and exists.
The product analysis result of laboratory test is as follows:
The rough secondary standard of this sample of project
Aluminum oxide (AL
