Description
Technical field
The utility model relates to the reaction unit that a kind of magnesium method is produced titanium sponge, especially relates to a kind of reaction unit that uses volume pump to produce titanium sponge as the magnesium method of feeding device.
Background technology
The reaction unit that existing magnesium method is produced titanium sponge generally comprises feeding device and inverted U reduction and distillation furnace.The process of reaction mainly comprises reduction process and still-process.From influencing the factor of reduction process, feed rate is a principal element that influences the titanium sponge structure.It influences speed of response, titanium sponge producer to the structure of, titanium sponge and porosity etc.
Experiment showed, that feed rate is excessive, local intense reaction easily takes place, temperature of reaction is too high, the titanium sponge easy-sintering, and residual chlorine is many in the product, influences quality product; Material speed is too small, reaction not exclusively, speed of response reduces, and generates thin titanium grain filling sponge titanium hole, is unfavorable for distillating of magnesium chloride in the still-process.Therefore, in the reduction process, normally carry out,, must stablize feed rate, have only the adding speed of titanium tetrachloride accurately controlled well, could guarantee to obtain helping distillatory titanium sponge structure to guarantee titanium sponge product structure and quality in order to make reduction reaction.
Existing feeding device adopts titanium tetrachloride header tank acquisition pressure reduction for the conveying of titanium tetrachloride provides power, relies on traditional glass rotameter and variable valve to carry out flow control.Along with the innovation of flowmeter technology, adopt more advanced turbo flow meter and Coriolis mass flowmeter to carry out flow metering subsequently again and carry out flow control.But there is several aspects problem in existing feeding device:
At first, from the angle of power is provided, the rising of titanium tetrachloride header tank material level can make upwards skew of feed rate, if untimely adjustment also can cause feed rate excessive, thereby influence the titanium sponge product structure.
Secondly, from the angle of flow control, there is following problems in various under meters.
To adopt glass rotameter to carry out flow control is example, if glass rotameter is demarcated again, directly reads, and data error is very big, and factors such as environment, medium also can influence the measuring accuracy of glass rotameter.For example, in actual production, the spinner-type flowmeter direct reading shows that feed rate is 260kg/h, and actual feed rate may arrive 300kg/h.
Use comparatively advanced turbo flow meter and mass flowmeter to carry out flow control and also have following problem: the turbo flow meter flow control accuracy can reach 0.5～1 grade, but this flow is counted volumetric flow and is detected, and belong to rotary-type equipment, lengthening along with duration of service, precision can decrease, and can not keep calibration characteristics, for a long time, in case clamping stagnation or turbine damage occur, then must change, and physical properties of fluids has considerable influence to flow characteristic.
Functional quality under meter, especially Ke Liaoli mass flowmeter be the highest under meter of tolerance range in the under meter with regard to its equipment, but also there are following problem in mass flowmeter:
1) its flow sensor installs and fixes and has relatively high expectations, and does not reach as setting accuracy, and is very big to the flow control accuracy influence;
2) mass flowmeter can not be used for big caliber at present, still is confined to the measuring tube caliber at present below 150 (200) mm, has so just limited the caliber of titanium tetrachloride pipeline, thus remote effect the titanium tetrachloride flow rate of fluid.
3) if corrosion of measuring tube inner wall abrasion or deposition fouling meeting influence measuring accuracy, especially the thin-walled tube measuring tube is more being shown.
4) pressure-losses is bigger, and most of model mass flowmeter weight and volume is bigger.
Except that the above, turbo flow meter and mass flowmeter price are very expensive, mass flowmeter especially, and its price is more than 2 times of turbo flow meter, cost of investment and maintenance cost height.
The utility model content
In view of this, the purpose of this utility model provides a kind of reaction unit that uses volume pump as the magnesium method production titanium sponge of feeding device, and it can address the above problem.
Above-mentioned purpose realizes by following proposal:
A kind of magnesium method is produced the reaction unit of titanium sponge, and it comprises feeding device and reduction and distillation furnace, and described feeding device inserts described reduction and distillation furnace by pipeline, it is characterized in that, described feeding device is a volume pump.
Reaction unit according to above-mentioned is characterized in that, described reduction and distillation furnace is the inverted U reduction and distillation furnace, and this inverted U reduction and distillation furnace comprises reduction reactor and distilling furnace.
The utility model has overcome in the prior art owing to the rising of titanium tetrachloride header tank material level produces the upwards phenomenon of skew of feed rate; Overcome the inaccurate phenomenon of metering of glass rotameter; Overcome turbo flow meter, the common shortcoming of mass flowmeter, and can stablize the feed rate of titanium tetrachloride, saved investment and maintenance cost.
