Abstract
The utility model discloses a power-saving type Oxyanthraquinone production device, which relates to the technical field of production devices for producing anthraquinone by adopting anthracene as raw materials through air oxidation, and comprises an anthracene melting kettle, an anthracene vaporizing kettle, a mixer, an oxygenizer, a flame arrester and a condensation box which are orderly connected through a pipeline, an inlet end of the mixer is further connected with a hot blast heater, and the inlet end of an air heat exchanger of the hot blast heater is connected on an air outlet of a Roots blower which uses a frequency converter and a variable frequency motor as a power source. The power-saving type oxidation anthraquinone production device aims at the defects in existing industry Oxyanthraquinone devices, uses the frequency converter and the variable frequency motor to drive the Roots blower, can adjust air quantity according to technological requirements, saves power, and the power can be saved by 35% than an original device when the power-saving type oxyanthraquinoneproduction device is used for producing every tons of anthraquinone.
Description
Technical field
The utility model relates to take anthracene as raw material, produces the production equipment technical field of anthraquinone through atmospheric oxidation.
Background technology
Take anthracene as raw material, through atmospheric oxidation, the dyestuff intermediate anthraquinone that makes (is commonly called as: the oxidation anthraquinone, to be different from synthetic anthraquinone) production, existing many decades is historical in China, technical process is: the anthracene of content 〉=90% is dropped into molten anthracene still heating and melting, squeeze into the vaporization still with submerged pump, to vaporize, the insulation of liquid anthracene passes into the 0.03Mpa superheated vapour again at 260～270 ℃ in the vaporization still in the still, and anthracene is gasified, enter mixing tank, with enter the fixed bed oxidizer that phosphorus/vanadium catalyst is housed after 〉=250 ℃ of warm airs mix, make anthracene be oxidized to anthraquinone, because the empty ratio of anthracene, catalyst activity, the isoparametric impact of oxidizing reaction temperature, the certain side reaction of simultaneously association, oxidized byproduct is Tetra hydro Phthalic anhydride or until carbonic acid gas and water, and what of side reaction directly affect the consumption of quality and the raw material anthracene of resultant anthraquinone.
The means of control oxidizing reaction state are in this device: 1, adopt the method for the flow of control superheated vapour to control the anthracene vaporization amount that enters oxidizer.2, employing is regulated the emptying method of roots blower air cushioning tank blow-off valve and is entered the oxidizer air capacity.3, adopt the fused salt recycle system to function of environment heat emission, take away reaction heat, to keep the relatively stable of temperature of reaction.
The defective that above-mentioned three kinds of control methods exist is: 1, in the manual operation regulation process, be difficult to precisely control, temperature of reaction is the result of many constitutive equations such as heat of being removed by anthracene quantity of steam, air capacity, speed of response (speed of response is subjected to again the variation of temperature of reaction and changes), reaction heat, salt bath, the particularly variation of temperature of reaction, bring the variation of oxidizing 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 temperature of reaction.During 2, because of the catalyst cycle activation, need than Wind Volume, so the configuration of roots blower air quantity is higher, and the wind supply quantity when normally producing is about 2/3 of nominal air delivery, and all the other air quantity of 1/3 are namely emptying by surge tank, cause electric weight to waste in a large number.3, oxidizing 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 utility model purpose is to propose to overcome the electricity-saving type oxidation anthraquinone production equipment that there is above problem in existing production industry.
The utility model comprises the molten anthracene still that is connected in series successively by pipeline, anthracene vaporization still, mixing tank, oxidizer, spark arrester and cooling cylinder, also connects hotblast stove at the entrance end of described mixing tank; The entrance end that it is characterized in that 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 defective that the utility model exists for existing industry oxidation anthraquinone device adopts frequency transformer and variable-frequency motor to drive roots blower, can regulate air quantity according to processing requirement, saves electric energy, produces anthraquinone per ton and can save power consumption 35% than original device.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model 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 a roots blower 8 that drives with frequency transformer and variable-frequency motor.
