Description
Technical field
It is that a kind of being used for processes the equipment, particularly a kind of titanium white waste acid membrane distillation concentration device that are hydrolyzed the titanium white waste acid of link in titanium white production that the utility model relates to.
Background technology
Recycling of water resource is the indispensable important natural resources of developing national economy, and at present, many local shortage of water resources in the world, the problem such as Appropriate application and water pollutions of this and water resource is closely related, and the water pollutions that industrial waste acid causes occupies very large ratio.Along with Environmental is administered and the input of protection, the attention that the process of industrial waste acid waste water is more and more subject to.Meanwhile, be the important channel solving shortage of water resources to the maximum utilization of water resource with reclaiming.
White powder of admiring is one of the most frequently used Chinese white, and the white powder industry of admiring of China obtains swift and violent development in the past between more than ten years, and exceedes Japan and leap to Asia maximum admire white powder country of consumption and producing country.Following under the drive of infrastructure construction, the demand of China to white powder of admiring still will keep strong growth.The industrial process of white powder has sulfuric acid process and chloridising two kinds by the emperor himself, and wherein sulfuric acid process is that current China produces one of main method of white powder of admiring, and Titanium White Production By Sulfuric Acid Process hydrolytic process can produce a large amount of spent acid (containing H
2sO
4about 20%, Fe
2+about 3%), namely 1 ton of white powder of admiring often is produced, the Waste Sulfuric Acid of 7-8 ton 20% and a large amount of acid waste water can be produced, these accessory substances are not as dealt carefully with, not only can cause the waste of resource, and serious environmental pollution can be caused, administering and recycle these spent acid, is solve environmental protection and sulfuric acid process to admire the important topic of white industrial development.
The processing method of current titanium white waste acid has: directly neutralisation, as with lime, and ammonia or caustic soda neutralization, but the method is cured the symptoms, not the disease, and fundamentally can not remove pollution, not only wastes resource but also easily cause secondary pollution, is not suitable for large-scale industrial production; In addition spent acid can be used for producing atlapulgite, aluminum sulfate, magnesium sulfate, manganese sulfate, ammonium sulfate, manganese acetate, bodied ferric sulfate NEW TYPE OF COMPOSITE poly-silicon iron aluminium sulphate etc.From these control measures, because produced spent acid quantity is larger, no matter be which kind of processing mode, all fundamentally can not solve the outlet of spent acid, waste acid concentration is only had to be only the most effective administering method, both can reclaim the sulfuric acid in hydrolysis spent acid, reduce environmental pollution, the sulfuric acid of recovery can have been reused again the production hydrolysis link of titanium dioxide.
Membrane Materials method is a kind of membrane contactor isolation technics based on physical process.This technology is the membrane separating process combined with evaporation process by membrane technology, its membrane material used for not the hydrophobic microporous membrane that soaks by pending feed liquid.It utilizes microporous barrier by different two-phases separately, and wherein one is hot side feed liquid mutually, directly contacts with hydrophobic film, and product side and film cold side are liquid phase or (gas) vapour phase, directly or indirectly contact with low-temperature aqueous solution.During system works, in the solution of hot side, volatile substances is that gas (vapour) state enters opposite side through film, realizes being separated.Its tool has the following advantages: the evaporating area in Membrane Materials process and the distance of condensing zone are only the thickness of film, and thus relatively traditional still-process has higher distillation efficiency; Process operation temperature is low, and the temperature of high-temperature feeding side is generally 50 ~ 60 DEG C, and low-temperature heat source thus can be utilized as the used heat in solar energy, underground heat and industrial production; Owing to only there being vapor-permeable fenestra, being therefore 100% to the theoretical interception capacity of some nonvolatile matters (as inorganic salts), very pure product can be obtained.Lack corresponding process equipment at present.
