Abstract
The invention provides a novel production technology of medicinal sodium chloride which comprises the following steps of dissolution, purifying, recrystallization, separation and drying. Refined halides solution is treated with the recrystallization in a double-effect evaporation system and forced circulation is adopted as a circulating power of the system, which leads to the balance and the stability of liquid phase of the system. The invention has the effects that after the double-effect forced circulation evaporation technology is adopted, the unit consumption of products is saved by 1.8 tons of steam and the hardening time is delayed for one month while the hardening breaking force drops by 80 percent; at the same time the intact rate of inner packing of products is improved and the production cost is reduced.
Description
Technical field
The present invention relates to a kind of industrial crude product sodium-chlor that utilizes,, make product reach the medicinal natrium chloratum double-effect forced circulation evaporation technique of medicinal standard through process for refining.
Background technology
It is single-effect evaporation that our factory originally prepared medicinal sodium chloride, and liquid phase adopts natural circulation.Such production, energy consumption height on the one hand; Heat power instability on the other hand, liquid phase is inhomogeneous, and product crystalline particle irregularity hardens easily; Energy consumption height so not only, product market competitiveness descends and product hardens has brought a lot of inconvenience to the user.Especially granularity is had the user of specific demand, the product that hardens can not use.When single-action was produced, it was 5.5 tons that product per ton consumes quantity of steam, and plate just hardens in 1 week of product.Sometimes will use very big external force for broken hardening, also because damaged need of external force changed, this has also increased cost to internal packing virtually.
Summary of the invention
For solving the problem that exists in the above-mentioned technology, the purpose of this invention is to provide a kind of medicinal natrium chloratum double-effect forced circulation evaporation technique, this technology becomes single-effect evaporation and imitates evaporation into two, and liquid phase is a pump circulation.Like this, both saved the usage quantity of steam in the production, and reduced production costs again and solved the defective that product easily hardens simultaneously.
For achieving the above object, the technical solution adopted in the present invention provides a kind of technology of medicinal natrium chloratum double-effect forced circulation evaporation, and this technology may further comprise the steps:
1., dissolving, raw material salt is dissolved in the water, when brinish concentration arrives 22 degree Beaume～24 degree Beaume, deliver to retort;
2., removal of impurities, after the above-mentioned feed liquid that enters retort reaches the regulation liquid level, open to stir, and feed steam and be warming up to 70 ℃～95 ℃, steam regulation feeding amount, keep feed temperature at 70 ℃～95 ℃, add bariumchloride, reacted 40 minutes, soda ash is added in the above-mentioned retort again, keep whipped state, continue reaction 20 minutes, keep temperature of reaction therebetween at 70 ℃～95 ℃, after reaction residual liquor sent into precipitation apparatus and leave standstill 24 hours, get supernatant liquor and send into one, two and imitate evaporating pots;
3., recrystallization, the supernatant liquor of above-mentioned steps in 2. delivered to one, two and imitated evaporating pots, reach and feed steam when specifying liquid level, the one steam admission pressure of imitating evaporating pot is controlled at 0.2MPa～0.28MPa, so both can guarantee that one imitated the water evaporates of jar, can guarantee again that two imitated the steam supply of evaporating pots; Imitate jar steam that produces by the secondary steam passage with one and send into two effect evaporating pots, two imitate the vacuum degree control of evaporating pot at 0.06MPa～0.09MPa, evaporation along with one, two effect evaporating pot moisture, the sodium-chlor crystallization is separated out, this one, two vapo(u)rization system of imitating the evaporating pot composition adopts pump circulation, make that system's liquid phase is even, the sodium-chlor crystalline particle is regular, and the situation of hardening obtains changing;
4., separate, through 3. constantly heavy the combining in the salt case of crystallization sodium-chlor of gained of step, again wet stock being sent into whizzer separates, salt behind the dehalogenation, with the purified water washing, once more the centrifuge dehydration of crystalline sodium-chlor is dried after the washing, simultaneously, for the mother liquor that will improve after yield will dry promptly gets rid of back liquid recovery, deliver to step 1.;
5., drying, the above-mentioned crystallization sodium-chlor that 4. forms is sent into moisture eliminator, 115 ℃～120 ℃ dry 15 minutes down, make product.
Effect of the present invention is to adopt after this two effect forced circulation evaporation technique, makes unit consumption of product save 1.8 tons of steam, the time dilation one month of hardening, and the broken external force that hardens descends 80%.Improve the internal packing serviceability rate of product simultaneously, reduced production cost.
