Abstract
The utility model relates to a naphthalene and air mixing device which comprises a venturi tube and a static mixer, wherein the venturi tube and the static mixer are connected. Compared with the prior art, the naphthalene and air mixing device has the advantages of being safe, reliable, good in sealing performance, convenient to maintain, high in efficiency and the like.
Description
Technical field
The utility model relates to the mixing arrangement of a kind of naphthalene and air, especially relates to the naphthalene that uses in a kind of technological process of naphthalene legal system phthalic anhydride and the mixing arrangement of air.
Background technology
At present, in the technological process of naphthalene legal system phthalic anhydride, the naphthalene gasified and air are after spraying through Venturi tube, directly enter reactor, so direct charging is because two bursts of mixing of materials insufficient, can increase load and the energy consumption of reactor, reduce catalyst life, cause certain financial burden.May there is the liquid be not gasified totally to enter reactor, cause temperature of reactor too high, can cause damage to catalyst simultaneously.
Summary of the invention
The purpose of this utility model is exactly that a kind of safe and reliable, airtight performance good, maintenance is convenient, efficiency is high naphthalene and the mixing arrangement of air are provided in order to overcome the defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions: the mixing arrangement of a kind of naphthalene and air, it is characterized in that, and this mixing arrangement comprises Venturi tube and static mixer, described Venturi tube is connected with static mixer.
Described Venturi tube comprises air intake, mixing chamber, diffuser and the gaseous mixture outlet set gradually, and described mixing chamber side is provided with the gas bleeding entrance.
Described static mixer comprises housing, is arranged on left-handed unit sheet and the dextrorotation unit sheet of inner walls.
The entrance of described static mixer is connected with Venturi tube by adpting flange.
Spacing between described static mixer and Venturi tube is less than 1m.
The mixed process of static mixer is that the hybrid element by being fixed in pipe carries out, effect due to hybrid element, while making fluid and when left-handed and dextrorotation, constantly change flow direction, not only push central liquid stream to periphery, and push peripheral fluid to center, thereby cause good radially mixed effect.With advancing, the turning effort of fluid self also can occur on the interface of adjacent elements junction therewith.This perfect radial circular flow immixture, obviously reduce thermograde, velocity gradient and the quality gradient of fluid on pipe section.The operation principle of static mixer, allow exactly fluid impact flow all kinds panel element in pipeline, increase the velocity gradient of fluid laminar motion or form turbulent flow, during laminar flow, be " cut apart-position is moved-again converged ", during turbulent flow, fluid is except above-mentioned three kinds of situations, also can produce violent eddy current in the section direction, there is very strong shearing force to act on fluid, make fluid further cut apart mixing, finally be mixed to form needed fluid.
Hybrid element in static mixer also can make in naphthalene drop adsorpting aggregation for not being gasified totally mixing on original paper simultaneously, makes liquid can't enter reactor, in order to avoid cause temperature of reactor too high, causes the infringement to catalyst.
Compared with prior art, the utlity model has following advantage:
One, safe and reliable: operating flexibility is large, and stable operation can not increase technological process dangerous.
Two, airtight performance is good: static mixer generally has seal preferably.
Three, maintenance is convenient: as static mixer loses efficacy, can from two Pressure gauges, embody fast.
Four, improve reaction efficiency: good mixing property, efficiency is high, easily realizes serialization production, reduces labour intensity, enhances productivity;
Five, economical and practical: simple in structure, equipment volume is little, floor space is little, not fragile, and cost of equipment is low, energy consumption is low, and operating cost is little.
The accompanying drawing explanation
The structural representation that Fig. 1 is static mixer of the present invention;
The charging flow chart formed with venturi in this device that Fig. 2 is static mixer of the present invention.
Below in conjunction with the accompanying drawings and the specific embodiments, the invention will be further described.
In Fig. 1 shown in label:
11 adpting flanges, 7 housings, 8 left-handed blade units, 9 dextrorotation blade units;
In Fig. 2 shown in label:
1 air intake, 2 suction gas accesses, 3 mixing chambers, 4 diffusers, 5 mist outlets, 6 mixer entrances, 7 housings, 8 left-handed unit sheets, 9 dextrorotation unit sheets, 10 mixed gas outlets.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1-2, the mixing arrangement of a kind of naphthalene and air, this mixing arrangement comprises Venturi tube and static mixer, described Venturi tube is connected with static mixer.
Described Venturi tube comprises air intake 1, mixing chamber 3, diffuser 4 and the gaseous mixture outlet 5 set gradually, and described mixing chamber 3 sides are provided with gas bleeding entrance 2.
Described static mixer comprises housing 7, is arranged on left-handed unit sheet 8 and the dextrorotation unit sheet 9 of inner walls, and the mixer entrance 6 be connected with gaseous mixture outlet 5, also has mixed gas outlet 10.The entrance of described static mixer is connected with Venturi tube by adpting flange 11.
In the charging flow process of Venturi tube and static mixer composition, air with certain pressure enters Venturi tube from air intake 1, during at a high speed by nozzle, pressure changes the speed energy into, by the gas in system from the suction gas access 2 suction mixing chambers 3, mixed gas enters diffuser 4 with certain speed, speed can change again pressure energy into, after the deceleration supercharging, from mist outlet 5, discharge, after enter static mixer from mixer entrance 6.In static mixer, mist is due to the effect of hybrid element, the time and when left-handed and dextrorotation constantly changes flow direction, not only core flow pushed to periphery, and is pushed peripheral fluid to center, thereby cause good radially mixed effect.Hybrid element also can make in naphthalene drop adsorpting aggregation for not being gasified totally mixing on original paper simultaneously, make liquid can't enter reactor, in order to avoid cause temperature of reactor too high, cause the infringement to catalyst.Gas after mixing is finally discharged from mixed gas outlet 10, enters reactor.
Hybrid element in static mixer also can make in naphthalene drop adsorpting aggregation for not being gasified totally mixing on original paper simultaneously, makes liquid can't enter reactor, in order to avoid cause temperature of reactor too high, causes the infringement to catalyst.
Distance between static mixer and Venturi tube should not surpass 1 meter, if distance is long, mixing can not reach required effect.
