The invention discloses a system for manufacturing medical sulfuric acid. The system comprises a boiling furnace, a contacting chamber, and an absorbing tower, which are orderly communicated, a heat-exchanger and a plurality of catalytic releasing devices are arranged in the contacting chamber, and the heat exchanger is arranged between the catalytic releasing devices. The system carries out a series of chemical reactions by utilizing ores as the raw material so as to obtain concentrated sulfuric acid, obtains medical sulfuric acid by diluting the concentrated sulfuric acid, and has the advantages of simple process, high utilization rate of raw materials, and satisfaction of bulk requirement.
Description
Technical field
The present invention relates to a kind of system manufacturing medical sulfuric acid, belong to medicine, chemical field.
Background technology
Sulfuric acid, chemical formula is H2SO4.Being a kind of colorless and odorless oily liquids, is the strong acid of a kind of high boiling point difficulty volatilization, soluble in water, can with arbitrarily than miscible with water.Sulfuric acid is one of staple product in basic chemical industry.It not only as the raw material of many Chemicals, but also is widely used in other sector of the national economy.Sulfuric acid is chemistry six large inorganic acid (sulfuric acid, nitric acid (HNO3), hydrochloric acid (HCl, formal name used at school spirit of salt), one of Hydrogen bromide (HBr), hydroiodic acid HI (HI), perchloric acid (HClO4), be also one of modal strong acid in all acid.A large amount of heat is released during concentrated sulfuric acid dissolution, therefore should " acid enters water, along wall, slowly falls, constantly stirs during diluting concentrated sulfuric acid.If " water is poured in the vitriol oil, temperature will reach 173 DEG C, cause acid solution to be splashed, cause potential safety hazard.
Sulfuric acid is a kind of colourless sticky oily liquids, is the strong acid of a kind of high boiling point difficulty volatilization, soluble in water, can with arbitrarily than miscible with water.Bright sulfur acid is colourless oil liquid, solidifies during 10.4 ° of C.During the acid of heating bright sulfur, boiling point 290 ° of C, and decomposition releasing part sulphur trioxide drops to till 98.3% until the concentration of acid, at this moment sulfuric acid is constant boiling solution, boiling point 338 ° of C.It is the ability providing proton that anhydrous slufuric acid embodies acidity, and bright sulfur acid still has very strong acidity, and the acidity of 98% sulfuric acid and bright sulfur acid there is no difference, and the oleum dissolving sulphur trioxide has been exactly a kind of super acid system, and acidity is better than bright sulfur acid.
Bright sulfur acid is colourless, thickness, and the oily liquids that conductivity is high is not volatile, but can produce a large amount of white vaporific sulfuric acid mists before ebuillition of heated.Bright sulfur acid is a kind of liquid of very polarity, and its dielectric coefficient is approximately 100.Because can mutual protonated the other side between its molecule and molecule, cause the electroconductibility that it is high, this is that this process is called as autoprotolysis because its occurs caused by two kinds of ions generating from even ionization.This reaction mechanism and pure phosphoric acid and pure hydrofluoric acid of an identical nature.But time required for this molecular balance is reached in bright sulfur acid, and then both are faster than above, are almost instantaneities.Medically usually need to use sulfuric acid, use field as various medical science, need by gas washing in SA production out.
Summary of the invention
The object of the invention is to the shortcoming and defect overcoming above-mentioned prior art, a kind of system manufacturing medical sulfuric acid is provided, this system utilizes ore to carry out a series of chemical reaction for raw material, finally obtain the vitriol oil, medical sulfuric acid is obtained after dilution, process is simple, high to the utilization ratio of raw material, meets batch demand.
Object of the present invention is achieved through the following technical solutions: a kind of system manufacturing medical sulfuric acid, comprise be communicated with successively fluidizing furnace, exposure chamber and absorption tower, be provided with heat exchanger and some catalyzer releasing devices in described exposure chamber, and heat exchanger is arranged between catalyzer releasing device.
Described fluidizing furnace is provided with opening for feed, slag notch, Primordial Qi outlet and inlet mouth, and described inlet mouth is arranged on the bottom of fluidizing furnace; Described Primordial Qi outlet is arranged on the top of fluidizing furnace, and Primordial Qi outlet is communicated with exposure chamber.
