过滤风速会影响美高梅在线登录网址除尘设备的哪些方面

文章发布: 发表时间: 2017-01-09 10:41:45

1、啥是过滤风速:过滤风速是反映美高梅在线登录网址除尘设备处理气体才能的主要技能经济指标,它对美高梅在线登录网址除尘设备的作业和功能都有很大影响。
1, what is the filtering wind speed: filtration wind speed is to reflect the environmental protection dust removal equipment to deal with gas ability of the main economic indicators, it has a great impact on the operation and function of environmental protection dust removal equipment.
2、风速对设备的影响:过滤风速偏高时,可以减小过滤面积和体积,下降占地面积,下降出资。可是,过滤风速挑选偏高,会影响除尘功率,添加清灰难度,过滤阻力增大,下降除尘滤袋使用寿命,带来运转和维护费用添加的疑问。实际上,挑选风速是一项较杂乱的作业,孤登时看待上述长处和缺陷是不够的,处理这个问题才是最主要。风速对除尘配件的难题:这些年,在环境保护要求愈来愈严厉的情况下,规划美高梅在线登录网址除尘设备作业中,合理地选定过滤风速也变得十分重要。
2, the impact of wind speed on the device: when the filtration speed is high, can reduce the filtration area and volume, decreased area, decreased investment. However, selection of high filtration velocity, dust will affect the power, adding cleaning difficulty, filtration resistance increased, decreased filter service life, bring the operation and maintenance costs add questions. In fact, selection of wind speed is a relatively messy job, look at the strengths and weaknesses in isolation is not enough, this problem is the most important. Wind speed on dust removal parts of the problem: over the years, in the case of environmental protection requirements more and more severe, the planning of environmental protection dust removal equipment, reasonable selection of filtration speed has become very important.
3、提高风速的影响:在处理风量不变的前提下,提高过滤速度可节约滤料,提高了过滤料的处理才能。但过滤速度进步后设备阻力添加,能耗增大,运转费用进步,现时过滤速度过高会把积聚在滤袋上的粉尘层压实,使过滤阻力添加。因为滤袋两边压差大,会使微细粉尘进入到滤料内部,乃至透过滤料,使出口含尘浓度添加。过滤风速高还会致使滤料上敏捷构成粉尘层,导致过于频频的清灰,添加清灰能耗,缩短滤袋的使用寿命。
3, improve the influence of wind speed: in the premise of the same air flow rate, improve the filtering speed can save the filter material, improve the processing ability of the filter material. But the filtration rate of progress after the resistance of the equipment is added, energy consumption increases, the operation cost is too high will progress, the filtration rate of the dust accumulation layer compaction in the filter bag, the filtration resistance added. Because of the large pressure difference on both sides of the bag, will make the fine dust into the internal filter, and through the filter, the outlet dust concentration. High speed filter will cause the filter on a layer of dust to agile, too frequently cleaning cleaning, add energy consumption, shorten the service life of the filter bag.
4、风速低影响哪些方面:在低过滤速度下,压力丢失少,功率高,但需求的滤袋面积也添加了,则美高梅在线登录网址除尘设备的体积、占地面积、出资费用也要增大。一般来说,处理较细或难于捕集的粉尘,含尘气体温度高,含尘浓度大和烟气含湿量大时宜取较低的过滤速度。
What 4, low wind speed effects: at low filtration velocity, pressure loss, high power, but the bag area requirements also added, is environmental protection equipment volume, area, investment cost will be increased. In general, the dust treatment is fine or difficult to capture the gas containing dust, high temperature, dust concentration in flue gas and the filtration rate of moisture content should take low.
