Description

A kind of acetylene cleaning Waste Sulfuric Acid processing equipment
Technical field
The utility model belongs to the processing technology field of acetylene cleaning Waste Sulfuric Acid, and in particular to a kind of acetylene cleaning Waste Sulfuric Acid Processing equipment.
Background technology
Production of PVC system acetylene cleaning device is miscellaneous using hydrogen sulfide, the hydrogen phosphide in the concentrated sulfuric acid and thick acetylene gas etc. Matter gas carries out redox reaction and removes, and a large amount of Waste Sulfuric Acids are produced in process of production.Because of the sulfur waste that acetylene section is produced Acid cannot also be recycled containing the impurity such as a large amount of carbide and S, P, gas washing in SA production producer, and these spent acid are such as without treatment It is discharged into environment, can not only makes water body or soil acidification, ecological environment is caused harm, and wastes ample resources, so Treatment to acetylene cleaning Waste Sulfuric Acid is most important.
Being related to the main method of acetylene cleaning sulfur waste acid treatment both at home and abroad at present has:
1st, phosphate fertilizer is manufactured, producing phosphate fertilizer using acetylene cleaning Waste Sulfuric Acid can not only solve Waste Sulfuric Acid process problem, may be used also Production cost is reduced, but due to phosphate rock resource skewness, this method is only suitable for the enterprise for locally having phosphate fertilizer plant.
2nd, Waste Sulfuric Acid pyrolysis recycle method, the method is to carry out sulfur waste acid cleavage at a lower temperature, in low sulfur dioxide furnace gas Conversion reaction steadily is carried out under conditions of concentration, the concentrated sulfuric acid that mass concentration is 98% is produced.The plant running conversion ratio is low, Exhaust emissions is exceeded, it is impossible to reach national environmental standard.
3rd, high temperature concentration method, the method is during thickened waste dilute sulfuric acid is heated, aoxidize organic matter generation therein, The reaction such as polymerization, is filtered to remove after being changed into dark gum or suspension, so as to reach the removal of impurity, concentrate the double of dilute sulfuric acid Harm of the severe corrosive and acid mist of purpose, but this method sulfuric acid again to equipment and operating personnel is very big.
4th, vapor-liquid separation type non-volatile solution concentration method, the method is that useless dilute sulfuric acid is squeezed into circulation by storage tank acid-proof pump Concentration tower is concentrated, and mist device is entered after then being heated through heat exchanger and diffuser forces atomization simultaneously further forced boiling, is separated Gas afterwards enters gas purifier after height demisting, is discharged after purification.Acid solution after separation returns to circulation concentration tower once again, Concentrated through iterative cycles and distilled, after reaching concentration requirement, recycled as raw materials for production, this method operating temperature receives main body material The limitation of material, it is impossible to more than 80 DEG C, if there is solids to separate out in concentration process, can influence the separation of heat-transfer effect and spent acid to imitate Really.
5th, oxidizing process, the method is, under suitable condition by the organic impurities oxidation Decomposition in Waste Sulfuric Acid, to make with oxidant It is changed into carbon dioxide, water, nitrogen oxide etc. and is separated from sulfuric acid, so that Waste Sulfuric Acid Recovery Purifying.This side Method is too high due to sulfuric acid concentration and temperature, has substantial amounts of acid mist to produce, and environmental pollution can be caused, while also to consume a certain amount of Sulfuric acid, makes the reduction of sulfuric acid yield, it is difficult to production application.
