Description
Technical field
The utility model relates to technical field of chemical, is specially a kind of bittern absorption unit.
Background technology
Bromine is one of important industrial chemicals, is the Main Branches of thalassochemistry industry, and miscellaneous inorganic bromide, bromate and the brominated organic compound derivative by it have special value in national economy and development in science and technology.Along with the development of national economy and the continuous developing of bromine series product, the importance of bromine is more and more outstanding, and its output constantly enlarges, always the state of development in being growing on and on.Especially in recent years, apply domestic and international modern technique, in the technology of obtaining through refining bromine aspect subsurface brine, concentrated seawater, obtained fast development.
In the bromine production process, need to extract bittern with brine pump, diluted acid and chlorine are successively added from the brine pump outlet pipe, bromide anion in pipe in bittern becomes simple substance bromine through acid with chlorine oxidation, through pipeline, the bittern after oxidation (oxidation solution) is sent into to the stripping tower top, then flow into splitter box, flow into two along the overflow groove with indention through splitter box, the oxidation solution flowed out by overflow groove is waterfall shape and flows down, with air (being blown into from the stripping tower bottom by gas blower) from bottom to top, contact, blow out free bromine, and blow out from tower top, flow into absorption tower, in absorption tower, brominated air and dioxide peroxide carry out reduction reaction, and water is absorbed.
The absorption unit that above-mentioned air acidifying blows out the standby bromine of legal system mainly has the following disadvantages: 1, absorption tower spray water xi Surface absorption area is little, the time is short, assimilation effect is poor, can not meet production requirement, and total recovery is on the low side, in 65% left and right, blow out the every side 105g of the brominated amount of waste liquid left and right; 2, the bittern at stripping tower top falls with the form of water column, and the contact area of air and bittern is little, the time is short, causes the output of later stage bromine lower, if strengthen wind speed, and the wind speed increasing will inevitably make bromine other impurity that adulterate, and causes quality product poor; 3, the oxidation solution flowed out from stripping tower's overflow groove is inhomogeneous, and impact blows out effect, cause bromine output lower, and the quality product of bromine is also poor.
The utility model content
Technical problem to be solved in the utility model is: a kind of efficient bittern absorption unit is provided, improves assimilation effect, more abundant in the raw brine reaction, improve the quality of products with yield in, reduce bromine exhaust emissions amount.
For solving the problems of the technologies described above, the utility model provides following technical scheme:
The bittern absorption unit, comprise the pipeline reactor, stripping tower and the absorption tower that are communicated with successively, and described pipeline reactor is provided with chlorine inlet, raw brine import and acid inlet, and described absorption tower and stripping tower are packing tower; Described absorption tower tower top is provided with cooling and reflux device, described absorption tower tower top with at the bottom of tower, by a circulation line, be communicated with, described circulation line is provided with recycle pump; The outlet of described stripping tower bittern inlet pipe is connected with a plurality of shower nozzles that fall.
Preferably, the described shower nozzle that falls has a shower nozzle nut be connected with stripping tower bittern inlet pipe, the bottom of described shower nozzle nut is a shower nozzle support body, on described shower nozzle support body, described fall shower nozzle ingress below be provided with a part flow arrangement, described part flow arrangement comprises a plurality of upper and lower tapered shunting plates that be arranged in parallel, the base diameter of described a plurality of spreader plates from top to bottom diminishes gradually, except a bottom spreader plate, the centre of each described spreader plate all has a through hole, and the diameter of described through hole from top to bottom diminishes gradually.
Preferably, the described ingress of falling shower nozzle also is provided with a back taper drainage tube and a hollow sleeved, and described sleeved, described shower nozzle nut and the described drainage tube that falls shower nozzle are set in the described ingress of falling shower nozzle from outside to inside successively.
Preferably, described stripping tower packed height is 10～15 meters.
Preferably, described absorption tower packed height is 3～8 meters.
After having adopted technique scheme, the beneficial effects of the utility model are: at first, because stripping tower and the absorption tower of this absorption unit is packing tower, absorb and become the absorption of filling surface moisture film by original spray water xi, increased simple substance bromine and water contact area and, slow down the falling velocity of bittern, extended the duration of contact of air-flow and bittern, increased assimilation effect; Secondly, described absorption tower tower top is provided with cooling and reflux device, is provided with circulation line between at the bottom of tower top and tower, this make raw material reaction carry out more fully, thoroughly, improve the quality of products with yield in, reduce bromine exhaust emissions amount; Finally, the part flow arrangement that falls shower nozzle adopts the form of successively falling shunting, strengthened the contact area of bittern and blow out air, therefore, not only improve the homogeneity of water distribution, can not form the water column phenomenon, avoided in tower forming Biased flow phenomenon, also reduced the falling velocity of current, improved and blown out effect.After testing, after adopting this absorption unit, blow out waste liquid by original 105g/m
3drop to 75-80g/m
3left and right, total recovery is brought up to the 73-75% left and right by original 70%, has absorbed liquid concentration by 70-80Kg/m
3carry to 90-100Kg/m
