气力输送系统中影响系统性能的因素

发布时间:2022-05-29 来源:http://www.sddyfd.com/

气力输送是清洁生产的一个重要环节,它是利用空气(或者其它气体)流作为输送动力,在管道中进行搬运粉粒状固体物料.物料在管道中的流动状态很复杂,根据物料在管道中的固气比都密相输送系统.气力输送系统广泛应用于石油,化工,冶金,建材,粮油,制药等工厂的一些原料,粉粒料的输送.那具体影响系统性能的因素有哪些,您知道嘛?接下来跟着小编一起去了解下吧!
Pneumatic conveying is an important part of cleaner production. It uses air (or other gas) flow as the conveying power to carry powdery and granular solid materials in the pipeline The flow state of the material in the pipeline is very complex. According to the solid gas ratio of the material in the pipeline, it is a dense phase conveying system Pneumatic conveying system is widely used in the transportation of raw materials, powder and granular materials in petroleum, chemical industry, metallurgy, building materials, grain and oil, pharmaceutical and other factories Do you know the specific factors that affect the system performance? Next, follow Xiaobian to learn about it!
一、侵蚀损耗
1、 Erosion loss
坚硬的砂砾状物料可以迅速地磨损气力输送系统部件,特别是在弯头供料的管道。磨损是通过撞击发生的,特别是在高速时,而磨损是通过粒子在表面滑动时的摩擦发生的。这在稀相气力输送和密相气力输送中都会发生的。旋转阀的转子顶端特别容易受到磨损,磨损严重时,会导致空气泄漏。当空气泄漏时,到达输送管道的空气就会减少,从而造成气力输送系统堵塞。如果气力输送过滤系统不定期清洗和维护,物料会进入风机,使其寿命减少。
The hard gravel like materials can quickly wear the components of pneumatic conveying system, especially in the elbow feeding pipeline. Wear occurs through impact, especially at high speeds, and wear occurs through the friction of particles sliding on the surface. This happens in both dilute phase pneumatic conveying and dense phase pneumatic conveying. The top of the rotor of the rotary valve is particularly vulnerable to wear, which will lead to air leakage in case of serious wear. When the air leaks, the air reaching the conveying pipeline will be reduced, resulting in the blockage of the pneumatic conveying system. If the pneumatic conveying filtration system is not cleaned and maintained regularly, the materials will enter the fan, reducing its service life.
二、物料受损
2、 Material damage
气力输送过程中产生了大量的能量,可以分解超过必要或所需的物料。与管道等物料的碰撞和摩擦会使物料受损,尤其是当物料易碎时。这不仅会降低材料的质量,而且还会产生气力输送系统无法使用的细粉。由于稀相气力输送中物料速度较高,物料悬浮在空气中,不经过管道表面,故向密相输送可解决部分物料降解问题。如果稀相输送是可行的选择,减少管道中弯角的数量将减少冲击,并可减少物料受损。
A large amount of energy is generated in the process of pneumatic conveying, which can decompose more than necessary or required materials. Collision and friction with pipes and other materials will damage the materials, especially when the materials are fragile. This will not only reduce the quality of the material, but also produce fine powder that cannot be used by the pneumatic conveying system. Due to the high speed of materials in dilute phase pneumatic conveying, the materials are suspended in the air and do not pass through the pipe surface, so conveying to dense phase can solve the problem of degradation of some materials. If dilute phase transportation is a feasible option, reducing the number of bends in the pipeline will reduce impact and reduce material damage.
三、冷凝
3、 Condensation
在气力输送系统中,许多物料在吸收水分后会结块或粘在管道上。冷凝是常见的原因。在某些情况下,当工厂运行时,温度在白天明显升高,在晚上下降。这些温度变化会导致凝结,物质会吸收,导致凝结或粘住。管道的微量加热或绝缘部分可以帮助防止这个问题。或者,由于这个问题通常发生在启动过程中,在使用前向气力输送管道中吹一段短时间的空气可以使管道干燥。如果这些解决方案都不适用,那需要一个空气干燥系统。
In pneumatic conveying system, many materials will agglomerate or stick to the pipeline after absorbing water. Condensation is a common cause. In some cases, when the plant is operating, the temperature increases significantly during the day and decreases at night. These temperature changes will cause condensation, and substances will absorb, causing condensation or adhesion. Trace heating or insulation of the pipe can help prevent this problem. Or, since this problem usually occurs during startup, blowing air into the pneumatic conveying pipe for a short time before use can dry the pipe. If these solutions are not applicable, an air drying system is required.
