钛制冷凝器在冶金工业中应用有如下优势

人气:164 评论:0 日期:2018-05-23 08:33:06

冶金工业中用钛设备能延长设备的使用寿命,提高劳动生产率,改善产品品质,延长设备检修周期,节省维修费用,减少对环境的污染,并能简化设备,方便操作,以及提高工艺的机械化和自动化程度。 钛在冶金行业中,主要用于有色金属的湿法冶金设备。湿法冶金过程一般是在一定温度、压力下,用酸、碱及各种化学溶剂溶浸矿料。所使用设备(如浸出过程的浸出槽、高压釜、搅拌装置,过滤过程的过滤筛板、泵、阀门、管道,电解过程的电解极板、热交换器及排烟机、收尘设备、烟道等),都要长期接触酸、碱、药剂和各种腐蚀性气体、烟尘,因而在一定温度下易受腐蚀与机械磨损,所以这些设备中常使用不锈钢或耐酸搪瓷、铅板、衬胶和耐酸涂层材料。没有使用钛材前设备腐蚀严重,事故多,溶液烟气的跑、冒、滴、漏严重,造成金属损失大,成本髙,劳动条件差,产品品质下降。
The use of titanium equipment in metallurgical industry can prolong the service life of equipment, improve labor productivity, improve product quality, prolong equipment maintenance cycle, save maintenance cost, reduce environmental pollution, simplify equipment, convenient operation, and improve the mechanization and automatization of process. Titanium in metallurgical industry is mainly used for hydrometallurgical equipment of non-ferrous metals. Hydrometallurgical processes usually use acid, alkali and various chemical solvents to dissolve mineral materials at a certain temperature and pressure. The equipment used (such as leaching tank, autoclave, stirring device, filtration sieve plate of filtration process, pump, valve, pipe, electrolysis plate, heat exchanger and smoke exhauster, dust collecting equipment, flue, etc.) should be exposed to acid, alkali, medicament and various corrosive gases and soot for a long time. Temperature is susceptible to corrosion and mechanical wear, so stainless steel or acid enamel, lead plate, lining and acid resistant coating materials are often used in these devices. The corrosion of the equipment before the use of titanium is serious, the accident is much, the running, running, dropping and leakage of the flue gas are serious, which causes the heavy metal loss, the cost, the poor working conditions and the quality of the product.

钛制冷凝器在冶金工业中应用,有如下优势。

①提高耐蚀性和使用寿命。钛对海水和蒸汽中氨的耐蚀性能好,因而使用寿命长,钛优于铜合金,钛制冷凝管的寿命可达20年。

②热交换性好。钛的优异的耐蚀性,可使钛管比铜管薄很多。虽然钛的热导率比铜低,但热交换能力却可提髙3%

③不需要防漏附属设备。使用钛冷凝器管后,泄漏率大幅度降低,节省处理时间和资金。

④能提高冷却水的流动速度。由于钛的耐蚀性好,泥沙和污垢等沉积物不易黏附在钛的表面,有助于提高水的流动速度。

⑤节省动力。由于钛管比铜管薄,在外径一定时,钛管的内径较大,可以节省泵的动力。

⑥钛制冷凝器的使用,可提高原子能发电站的运转率和安全性。

Titanium condenser has the following advantages in metallurgical industry.

(1) improve corrosion resistance and service life. Titanium has good corrosion resistance to ammonia in seawater and steam, and therefore has long service life. Titanium is superior to copper alloy, and the life of titanium refrigeration condensing tube can last up to 20 years.

(2) the heat exchange is good. Titanium has excellent corrosion resistance, making titanium tubes much thinner than copper tubes. Although the thermal conductivity of titanium is lower than that of copper, the heat exchange capacity of titanium can be increased by 3%.

There is no need to prevent leakage of auxiliary equipment. After using the titanium condenser tube, the leakage rate will be greatly reduced, and the processing time and capital will be saved.

(4) can improve the flow speed of cooling water. Because of the good corrosion resistance of titanium, sediments such as silt and dirt are not easily adhered to the surface of titanium, which helps to improve the flow velocity of water.

Save power. Because the titanium tube is thinner than the copper tube, when the outer diameter is constant, the inner diameter of the titanium tube is large, so that the power of the pump can be saved.

The use of titanium condenser can improve the operation rate and safety of the nuclear power station.

钛在冶金工业中用于铜、镍、钴、铅、锌等冶炼设备的电解阴极种板、加热器、冷却器、反应器、阴极辊筒,钼冶炼的高压釜,铜矿湍动冷却塔,焦化厂捕尘器以及泵、阀、风机、管道等。另外干电池原料的二氧化锰电解,也采用金属钛阳极。实践表明,钛材在这些领域中的应用,生产上是可行的,技术上是先进的,经济效果显著。

Titanium is used in metallurgical industry for electrolytic cathode type plate, heater, cooler, cooler, cooler, reactor, cathode roller, molybdenum smelting autoclave, copper mine turbulent cooling tower, coking plant dust collector, pump, valve, fan, pipe and so on. In addition, the manganese dioxide used for dry battery is also electrolyzed by metal titanium. Practice shows that the application of titanium in these fields is feasible, technically advanced and economically effective.
