Abstract
The invention discloses a power-saving type oxyanthraquinone production device, and relates to the technical field of production device for producing anthraquinone by adopting anthracene as raw material and through air oxidation. The production device comprises an anthracene melting kettle, an anthracene vaporization kettle, a mixer, an oxygenizer, a flame arrester and a condensation box which are successively in series connection through pipelines; an inlet end of the mixer is further connected with a hot blast furnace, and the inlet end of an air heat exchanger of the hot blast furnace is connected on an air outlet of a Roots blower which adopts a frequency converter and a variable frequency motor as power sources. The power-saving type oxyanthraquinone production device aims at the defects existing in a conventional industry oxyanthraquinone device, adopts the frequency converter and the variable frequency motor to drive the Roots blower, can adjust air quantity according to technological requirements, saves electric energy, and allows the power consumption to be saved by 35% than the original device when the power-saving type oxidization anthraquinone device is used for producing each ton of anthraquinone.
Description
Technical field
The present invention relates to anthracene is raw material, produces the production equipment technical field of anthraquinone through atmospheric oxidation.
Background technology
Take anthracene as raw material, through atmospheric oxidation, obtained dyestuff intermediate anthraquinone (is commonly called as: oxidation anthraquinone, with be different from synthesis anthraquinone) production, many decades history is had in China, technical process is: the anthracene of content >=90% is dropped into molten anthracene still heating and melting, vaporization still is squeezed into submerged pump, the insulation of liquid anthracene will to be vaporized in still at 260 ~ 270 DEG C, 0.03Mpa superheated vapour is passed into again in vaporization still, anthracene is gasified, enter mixing tank, the fixed bed oxidizer that phosphorus/vanadium catalyst is housed is entered after mixing with >=250 DEG C of warm airs, anthracene is made to be oxidized to anthraquinone, due to anthracene sky ratio, catalyst activity, the isoparametric impact of oxidizing reaction temperature, the side reaction that association is simultaneously certain, oxidized byproduct is Tetra hydro Phthalic anhydride or until carbonic acid gas and water, the number of side reaction, directly affect the quality of resultant anthraquinone and the consumption of raw material anthracene.
In this device, the means of controlled oxidization response behaviour are: 1, adopt the method for the flow controlling superheated vapour to control the anthracene vaporization amount entering oxidizer.2, adopt the method emptying to roots blower air cushioning tank blow-off valve to regulate and enter oxidizer air capacity.3, adopt the fused salt recycle system to function of environment heat emission, take away reaction heat, to maintain the relatively stable of temperature of reaction.
The defect that above-mentioned three kinds of control methods exist is: 1, in manual operation regulation process, be difficult to precisely control, temperature of reaction is the result of many constitutive equations such as the heat removed by anthracene quantity of steam, air capacity, speed of response (speed of response changes by the change of temperature of reaction again), reaction heat, salt bath, the particularly change of temperature of reaction, bring the change of oxidizing reaction speed, bring the change of reaction heat, if side reaction is risen, reaction heat discharges in a large number, the more difficult grasp of temperature of reaction.2, because of catalyst cycle activate time, need comparatively Wind Volume, therefore the configuration of roots blower air quantity is higher, and wind supply quantity when normally producing is about 2/3 of nominal air delivery, all the other air quantity of 1/3 are namely emptying by surge tank, cause electricity to waste in a large number.3, oxidation reaction heat adopts fused salt circulation, and by pipeline fused salt storage tank to function of environment heat emission, a large amount of reaction heat energy is not utilized.
Summary of the invention
The present invention seeks to propose to overcome the electricity-saving type oxidation anthraquinone production equipment that existing production industry exists above problem.
The present invention includes be connected in series successively by pipeline molten anthracene still, anthracene vaporization still, mixing tank, oxidizer, spark arrester and cooling cylinder, also connect hotblast stove at the entrance end of described mixing tank; It is characterized in that the entrance end of described hotblast stove air heat exchanger is connected to one by frequency transformer and variable-frequency motor on the air outlet as the roots blower of propulsion source.
The present invention is directed to the defect that existing industry oxidation anthraquinone device exists, adopt frequency transformer and variable-frequency motor to drive roots blower, air quantity can be regulated according to processing requirement, save electric energy, produce anthraquinone per ton and can save power consumption 35% than original device.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention is serially connected with molten anthracene still 1, anthracene vaporization still 2, mixing tank 3, oxidizer 4, spark arrester 5 and multi-stage condensing case 6 successively by pipeline, also connects the outlet of hotblast stove air heat exchanger 7 at the entrance end of mixing tank 3.
The entrance end of hotblast stove air heat exchanger 7 is connected on the air outlet of the roots blower 8 that drives with frequency transformer and variable-frequency motor.
Claims (1)
1. an electricity-saving type oxidation anthraquinone production equipment, comprise be connected in series successively by pipeline molten anthracene still, anthracene vaporization still, mixing tank, oxidizer, spark arrester and cooling cylinder, be also connected with the exit end of hotblast stove air heat exchanger at the entrance end of described mixing tank; It is characterized in that the entrance end of described hotblast stove air heat exchanger is connected to one by frequency transformer and variable-frequency motor is on the air outlet of the roots blower of propulsion source.
