Description
Technical field:
The utility model relates to a kind of Resorcinol neutralization reaction device.
Background technology:
Resorcinol is a kind of important fine chemistry industry organic raw material, is widely used in rubber, plastics, medicine, agricultural chemicals, dye well electron chemistry product.Wherein be mainly used in tire fabric impregnation, use for synthetic rubber tacky resin, wood gluing plate with high performance tackiness agent, organic intermediate amino phenol and benzophenone UV light absorber.The technology of at present the most traditional in the world production Resorcinol is sulfonated alkali fusion method, the most of enterprises that comprise states such as China, the U.S., India, Russia all adopt this method production, the production technique of Resorcinol: the sulfonation under the effect of catalyzer of benzene and oleum, neutralization, alkali fusion, acidifying, distill finished product.Its technical process is followed successively by: sulfonation, neutralization, alkali fusion, acidifying, distillation, finished product.At present, sulfonated alkali fusion method is produced the problem that the technology of Resorcinol mainly exists: old-fashioned sulfonation, neutralization reaction technology are that the oleum with benzene and 65% carries out sulfonation, sulfonation material and 25% sodium hydroxide solution carry out neutralization reaction, introduce a large amount of sulfuric acid in the reaction system, just had a large amount of H in the sulfonated products
2SO
4, during neutralization reaction, need a large amount of NaOH, produce a large amount of inorganic salt Na simultaneously
2SO
4Gu useless and waste liquid have increased raw materials cost and useless admittedly processing costs; Solid Na
2SO
4Also to from system, filter out.Between the neutralization reaction of benzene disulfonic acid and NaOH, produce a large amount of heat owing to be 25% sodium hydroxide solution of usefulness, have a large amount of water in the reaction system, though temperature of reaction system has raise, the quality of heat is very low, heat can not reclaim.
During next step alkali fusion, contain sodium 1,3-benzenedisulfate salt in and mother liquor, be added drop-wise to in the coal combustion direct-fired alkali-melting vessel, a large amount of moisture content vaporization of need absorbing heat in the mother liquor is evaporated with the form of water vapor, this needs a large amount of heats again.The stove of coal combustion, floor space is big, and thermo-efficiency is low.
The shortcoming of old-fashioned neutralization reaction is:
1, owing to there is vitriolic to exist, the neutralization back generates sodium sulfate, after the filtration, produces a large amount of solid wastes.
2, go neutralization with 30% NaOH, contain a large amount of water in the liquid, next step reaction does not need water, owing to introduced water in the system, water is evaporated, and consume a large amount of heat, causes energy dissipation.
3, the acid-base neutralisation reaction produces a large amount of heat, and after the neutralization, system is the aqueous solution, and the bad recovery of heat causes calorific loss.
4, neutralization reaction is carried out in alkali-melting vessel, periodical operation, and labour intensity is big, and efficient is low.
5, the cost height of alkali-melting vessel and coal furnace, cost of investment is big.Because alkali-melting vessel is directly to heat on fire, the high seriously corroded of local temperature, will change again every half a year, the running cost height.
The utility model content:
The utility model provides the reaction unit in a kind of Resorcinol neutralization reaction process, and it can solve huge, the challenge of reaction unit equipment in the neutralization reaction.
The utility model can also solve in the neutralization reaction process discontinuous, and efficient is low, energy consumption is big, raw material consumption is many, produce the many problems of solid waste.
A kind of Resorcinol neutralization reaction device, this device comprises static mixer, feed end at static mixer is provided with a distribution head, and described distribution head has two feed cavity, respectively connects an opening for feed on the cavity, a mouth is connected with sulfonation material storage tank, another mouthful is connected with liquid alkali storage tank, and the other end of static mixer links to each other with the material collection groove, is provided with mixed cell in the static mixer, outer setting has isulating jacket, and static mixer seals.
The mixed cell of described static mixer is the SK type, SV, SX or SL.
Described static mixer is two sections and is in series, or multistage is in series.
Described static mixer outer setting heating jacket.
Described distribution head has two feed cavity, and the centre separates with dividing plate, makes material not contact in distribution head.
Described storage tank links to each other with volume pump, volume pump outlet with an opening for feed link to each other, adorn a deoscillator on the sulfonation material pipeline; Described storage tank links to each other with volume pump, and the volume pump outlet links to each other with an opening for feed of distribution head, adorns a deoscillator on the liquid alkali pipeline.Distribution head links to each other with static mixer; Static mixer links to each other with receiving tank, and receiving tank links to each other with fly-ash separator again.
Described volume pump is the high-pressure corrosion-resistant pump.
Static mixer is a kind of high-efficiency mixing device that does not have moving parts, extrudes at oil, chemical industry, plastics, environmental protection industry (epi) is used widely.Compare with whipping device, have that flow process is simple, advantages such as compact construction, energy consumption are little, less investment, good mixing property.In the process of a lot of mixing, reaction, enhancement of heat transfer, can replace traditional relevant device.
The mixed cell of the static mixer that the utility model is used is the SK type, is made up of the spiral plate of a plurality of positive and negative alternates.Static mixer generally is not suitable for the reaction system that a large amount of solid phases are arranged, and the utility model has made full use of the characteristics of this neutralization reaction, the feeding temperature height, the a large amount of again heat releases of reaction, heat makes the instant water in the system become steam, high-temperature steam makes salt become powder, and the pressure of system rises very highly again, and the mobile power that provides of material is provided.React the characteristics of self just because of this, a kind of static mixer is used in the serialization of Resorcinol neutralization reaction workshop section, is achieved.
The mixing process of static mixer is to be undertaken by the hybrid element that is fixed in the pipe, because the effect of hybrid element, when making fluid and when left-handed and dextrorotation, when material flows in the static mixer high speed, constantly cut apart-mix-cut apart-mix by its inner mixed cell, make that material is constantly disperseed, shears, reaction is able to moment, fully finishes.
