Description
Technical field
The technology of the present invention relates to take anthracene as raw material, through air oxidation, makes the process units technical field of anthraquinone.
Background technology
Take anthracene as raw material, through air oxidation, the dyestuff intermediate anthraquinone making (is commonly called as: oxidation anthraquinone, to be different from synthetic anthraquinone) production, in China, existing many decades is historical, technical process is: the anthracene of content >=90% is dropped into molten anthracene still heating and melting, with submerged pump, squeeze into vaporization still, in vaporization still, pass into 0.03Mpa superheated steam again, make anthracene gasification, enter blender, after mixing with >=250 ℃ of hot-airs, enter the fixed bed oxidator that phosphorus/vanadium catalyst is housed, make anthracene be oxidized to anthraquinone, due to the empty ratio of anthracene, catalyst activity, the isoparametric impact of oxidizing reaction temperature, the certain side reaction of association simultaneously, oxidized byproduct is phthalic anhydride or until carbon dioxide and water, the number of side reaction, directly affect the consumption of quality and the raw material anthracene of product anthraquinone.
The means of controlling oxidation reaction state in this device are: 1, adopt the method for the flow of controlling superheated steam to control the anthracene vaporization amount that enters oxidator.2, adopt the emptying method of roots blower air cushioning tank atmospheric valve is regulated and enters oxidator air capacity.3, adopt the fused salt circulatory system to function of environment heat emission, take away reaction heat, to maintain the relatively stable of reaction temperature.
The defect that above-mentioned three kinds of control methods exist is: 1, in manual operation regulation process, be difficult to precisely control, reaction temperature is the result of many constitutive equations such as heat of being removed by anthracene quantity of steam, air capacity, reaction speed (reaction speed is subject to again the variation of reaction temperature and changes), reaction heat, salt bath, the particularly variation of reaction temperature, bring the variation of oxidation reaction speed, bring the variation of reaction heat, if side reaction is risen, reaction heat discharges in a large number, the more difficult grasp of reaction temperature.While 2, activating because of catalyst cycle, need be compared with Wind Volume, therefore the configuration of roots blower air quantity is higher, and wind supply quantity while normally producing is about 2/3 of nominal air delivery, all the other air quantity of 1/3 are emptying by surge tank, cause electric weight to waste in a large number.3, oxidation reaction thermal recovery fused salt circulation,, is reacted in a large number heat energy and is not utilized to function of environment heat emission by pipeline fused salt storage tank.
Summary of the invention
The present invention seeks to propose to overcome the energy-saving oxidation anthraquinone process units that existing production industry exists above problem.
The present invention includes blower fan, also comprise the molten anthracene still, anthracene vaporization still, blender, oxidator, spark arrester and the cooling cylinder that by pipeline, are connected in series successively, entrance point at described blender also connects hot-blast stove, also comprises the fused salt circulatory system of carrying out heat exchange with described oxidator; It is characterized in that: material-air heat exchanger is set in spark arrester, in the pipeline of the described fused salt circulatory system, is connected in series fused salt-air heat exchanger; The delivery outlet of blower fan connects air cushioning tank, three air outlet slits is set on air cushioning tank: primary outlet is connected to the air intlet of hot-blast stove by the first air flow rate adjustment valve; Second outlet is connected to the air intlet of material-air heat exchanger by the secondth air flow rate adjustment valve, the air outlet slit of material-air heat exchanger is connected to the air intlet of hot-blast stove again; The 3rd outlet connects the air intlet of fused salt-air heat exchanger by the 3rd air flow rate adjustment valve, the air outlet slit of described fused salt-air heat exchanger is also connected to the air intlet end of hot-blast stove again.
Operation principle of the present invention is: the cold air that adopts air cushioning tank that blower fan is supplied with is divided into three tunnels: first via cold air can directly enter the airduct that supplies of hot-blast stove; The second road cold air enters the material-air heat exchanger in spark arrester, the high-temperature material entering after reacting with oxidator in spark arrester carries out heat exchange, can make the material cooling in spark arrester, make to enter the cold air in material-air heat exchanger in spark arrester simultaneously and heated up, by the air outlet slit end of the material-air heat exchanger in spark arrester, entered the airduct that supplies of hot-blast stove; Third Road cold air enters and fused salt-air heat exchanger carries out heat exchange with heat from the fused salt circulatory system, and this air after heating enters hot-blast stove for airduct by the port of export of the air of fused salt-air heat exchanger.
The present invention takes full advantage of the oxidation reaction heat that high-temperature molten salt and high-temperature material are taken out of, by material-air heat exchanger preheating normal temperature air in fused salt-air heat exchanger and spark arrester, for hot-blast stove provides preheated air, after heat exchanger reclaims oxidation reaction heat energy, the EAT of hot-blast stove becomes 180 ℃～200 ℃ hot blasts from the normal temperature temperature of original device, greatly reduce the coal consumption of hot-blast stove, there is energy-conservation effect.
Separately, blower fan of the present invention, for adopting the roots blower of converter technique, can regulate air quantity according to technological requirement, produces anthraquinone per ton and can save power consumption 35% than original device.
