Abstract
The invention discloses a kind of intelligent reactor and the recoverying and utilizing method of hydrofluoric acid and hydrochloric acid nitration mixture, reactor is redesigned so that the reactor that the present invention is used is capable of the recycling of perfect cooperation nitration mixture, time saving and energy saving.Recovery method of the invention is, to witherite powder (barium carbonate) is continuously added in the reactor equipped with nitration mixture, controls pH value and reaction end, and reaction terminates rear suction filtration, and residue washing drying obtains barium fluoride product；It is barium chloride solution product after filtrate impurity removal and purification, the external direct marketing of fluid product can be made, it is also possible to be condensed into solid product for sale.Nitration mixture is processed into two products of barium fluoride and barium chloride by above-mentioned recoverying and utilizing method, is fully used nitration mixture, is turned waste into wealth, while again free from environmental pollution.
Description
Technical field
The present invention relates to chemical field, more particularly, to the recovery of a kind of intelligent reactor and hydrofluoric acid and hydrochloric acid nitration mixture
Application way.
Background technology
Hydrofluoric acid is the aqueous solution of hydrogen fluoride gas, limpid, colourless, smoke corrosive liquids, there is severe irritation gas
Taste.- 83.3 DEG C of fusing point, 112.2 DEG C of boiling point, density 0.888g/cm3.Soluble in water, ethanol, is slightly soluble in ether.Because hydrogen atom
The ability combined and between fluorine atom is relatively strong so that hydrofluoric acid can not be ionized completely in water, so low concentration in theory
Hydrofluoric acid is a kind of weak acid (actually belonging to middle strong acid by its dissociation constant).With extremely strong corrosivity, can consumingly corrode
Metal, glass and siliceous object.Such as suck steam or contact skin can cause to be difficult to cure burns.Due to hydrofluoric acid dissolution
The ability of oxide, it plays an important role in the purification of aluminium and uranium.Hydrofluoric acid is also used for etching glass, can carve figure
Case, mark scale and word；Semi-conductor industry uses it to remove the oxide of silicon face, and it can serve as different in oil plant
The catalyst of the alkylated reaction of butane and n-butene, can also use during " pickling " of the oxygenate impurity for removing stainless steel surfaces
To hydrofluoric acid.Hydrofluoric acid is also used for the synthesis of various organic fluorocompounds, such as Teflon (polytetrafluoroethylene (PTFE)) also has freon one
The refrigerant of class.
Hydrochloric acid, is the aqueous solution of hydrogen chloride, belongs to unitary inorganic strong acid, and industrial use is extensive.The proterties of hydrochloric acid is colourless
Transparent liquid, there is strong sharp aroma, with corrosivity higher.Concentrated hydrochloric acid (mass fraction is about 37%) is with extremely strong
Volatility, therefore fill concentrated hydrochloric acid container open afterchlorinate hydrogen can volatilize, combined generation with the vapor in air
Hydrochloric acid droplet, makes bottleneck top acid mist occur.Hydrochloric acid is the main component of hydrochloric acid in gastric juice, and it can promote food digestion, resist micro-
Biological infection.Hydrochloric acid is colourless liquid (industrial hydrochloric acid can show slightly yellow because there is impurity trivalent iron salt), is corrosive, and is chlorine
Change the aqueous solution of hydrogen, with penetrating odor, concentrated hydrochloric acid is dissolved in water has heat to release.It is dissolved in alkali lye and occurs to neutralize instead with alkali lye
Should.Because concentrated hydrochloric acid has volatility, the hydrogen chloride gas for volatilizing act on forming hydrochloric acid droplet with the vapor in air,
So can be appreciated that white haze.Hydrochloric acid is a kind of inorganic acid, is had a wide range of applications in industrial processes, the refining of such as metal.
Recently as continuing to develop for fluorine chemical industry, the yield of the fluorine product such as fluorinated refrigerant fluoroplastics is increasing.
In its production process, because technique needs, the mixed acid for generating substantial amounts of hydrofluoric acid containing and hydrochloric acid (hereinafter referred to as mixes
Acid).The composition of the mixed acid be hydrofluoric acid 10~40%, hydrochloric acid 3~20%, remaining be water, also a small amount of other impurities.Should
Mixed acid cannot direct marketing, need to by treatment.The current use producer of the nitration mixture is mostly without card underground factory, these producers
Gone to process metal surface with nitration mixture, acid-bearing wastewater is directly discharged in production process, and environmental pollution is extremely serious.Even accredited
Manufacturer discharges after can only also being neutralized to the hydrochloric acid in nitration mixture.
From from the point of view of recycling economy, mixed acid is recycled, with the Acid of Hydrofluoric Acid Production in mixed acid, other are fluorinated
Chemical product, so as to be separated with hydrochloric acid, makes Fluorine contained chemicals and each self-sales of Related product formed by hydrochloric acid.So can both reduce
Substantial amounts of fluorine-containing industrial waste, improves environment, and maximum resource utilization rate can be realized again, production cost is reduced, with obvious society
Can benefit and economic benefit.
The content of the invention
It is an object of the invention to provide a kind of intelligent reactor and the recoverying and utilizing method of hydrofluoric acid and hydrochloric acid nitration mixture,
Using witherite powder (barium carbonate) respectively with nitration mixture in hydrofluoric acid and hydrochloric acid reaction, so as to obtain barium fluoride product and barium chloride
Aqueous products, nitration mixture is utilized completely, is turned waste into wealth, and realizes no pollution, zero-emission.
In order to solve the above-mentioned technical problem, adopt the following technical scheme that：
