Abstract
Acid residuum formed in the process of chemical purification is heated to flow, and then, is additionally provided with ammonia water of certain consistence; a certain temperature is kept; oil and ammonium sulfate solution, which are formed by reaction, are naturally layered and can be separately poured into a storage tank.
Description
The present invention is the treatment method of acid residuum in the chemical industry highly industry.
Acid sludge in Japan's J49-126701 patent is handled and is: in addition an amount of waste oil or light oil in the acid sludge, most of H
2SO
4Water-soluble, in the oil a spot of residual sulfuric acid with in the lime and after, can make heavy oil or be light oil through catalysis.This method neutralizes with lime, must have precipitation to become waste residue.
Acid sludge in the Japan J76-002919 patent is handled, with the H in the acid sludge
2SO
4Concentration adjust best 65-90%, be heated to 150-190 ℃ while stirring, make organism dehydrogenation and carbonization, filtration can get carbonized polymers and sulphuric acid soln, carbonized polymers can be used as activated carbon adsorbent, and this method also will add sulfuric acid when handling acid sludge, has sour gas to overflow with water vapor to cause environmental pollution being heated to 150-190 ℃, last sulphuric acid soln corrosion is also comparatively serious, the requirement for anticorrosion height.
Japan J53-144875 handles sulfur acid waste residue method: add Mg(OH)
2Slurries, refuel burns, and absorbs the SO that burning produces with aqueous suspension
2The MgSO that generates
4The aqueous solution be disposed to rivers, fuel that this method consumption is a large amount of and Mg(OH)
2, do not produce useful matter, and also generate MgSO at last
4The discharging rivers, still unfavorable in environmental protection.
Purpose of the present invention is exactly the problem that will solve above existence, makes the acid sludge after the processing all become available material.
Solution of the present invention:
But acid sludge is heated to flow state, after stopping heating, add ammoniacal liquor, the limit edged stirs, stop adding ammoniacal liquor during to PH=7, reaction is violent and rapid, is static layering after the reaction, and the division is clearly demarcated, the upper strata is an oil, lower floor is the sulphur aqueous ammonium, and the lower pipeline of reacting in the actual production should add transparent sight glass, and oil and ammonium sulfate solution are put into separately storage tank respectively.
The present invention compares with above-mentioned several method, does not produce MgSO
4Aqueous solution discharge does not need refuel to burn.
Do not produce lime and so on precipitation, decompose the oil that comes out to use at once, without catalytic decomposition.
Not existing to re-use sulfuric acid concentration adjusting problem, without filtration process, do not have throw out, is simple oil water separation process.
The novel substance that present method produces all is an available, does not waste material and does not also produce new pollutent.
