文章发布: 发表时间: 2017-05-16 10:27:33

除尘滤袋的面料规划应尽量寻求高效过滤、易于粉尘剥离及经久耐用作用。除尘滤袋是美高梅在线登录网址除尘设备里的主要配件,美高梅在线登录网址除尘设备一般依据含尘气体的性质、粉尘的性质和除尘器的清灰方法的不一样而挑选所需除尘滤袋,所以挑选除尘滤袋的留意重点也是不一样的。
Dust filter bag fabric planning should be as far as possible to seek efficient filtration, easy to dust stripping and durable role. Dust bag is the main parts in environmental protection equipment, cleaning method of nature environmental protection equipment based on the general nature of the gas containing dust and dust and dust are not the same as the selected required dust bag dust filter bag, so the selection of the focus of attention is not the same.
一,依据工况条件的请求挑选性价比适合的除尘滤袋。
First, according to the requirements of working conditions, choose the filter bag which is suitable for cost performance.
1,气体温度。气体温度低于130℃挑选常温除尘滤袋,温度在130℃-260℃之间挑选高温除尘滤袋。
1, gas temperature. When the gas temperature is lower than 130 DEG C, the dust filter bag is selected at normal temperature. The high temperature dust filter bag is selected at the temperature between 130 and -260 degrees centigrade.
2,气体湿度。含尘气体按相对湿度分为三种状况:枯燥气体(相对湿度在30%以下),一般状况(相对湿度在30%-80%之间)和高湿气体(相对湿度80%以上)。当气体湿度高就应当挑选覆膜防水布袋。
2, gas humidity. Dust gas is divided into three states according to relative humidity: dry gas (relative humidity below 30%), general conditions (relative humidity between 30%-80%) and high humidity gas (relative humidity above 80%). When the gas humidity high should choose waterproof film bag.

3,气体的化学性。在各种炉窑烟气和化工废气中,常富含酸、碱、氧化剂、有机溶剂等化学成分。地点以挑选滤袋时应依据烟气中所富含化学成分进行合理挑选耐酸耐碱抗氧化的除尘滤袋。
3, the chemistry of gases. In all kinds of kiln flue gas and chemical waste gas, it is often rich in acids, alkalis, oxidants, organic solvents and other chemical components. When selecting filter bags, the filter bag with acid, alkali and oxidation resistance should be selected according to the chemical composition contained in the smoke.
二、依据粉尘的特别性质选用除尘布袋。
Two, according to the special nature of dust, choose dust bag.
1,粉尘的湿润性和黏着性。假如粉尘是吸湿性的并且黏着性强,就挑选防水覆膜滤料的除尘滤袋。
1, the wettability and adhesion of dust. If the dust is hygroscopic, and adhesion is strong, select waterproof membrane filter bag filter bag.
2,粉尘的可燃性和荷电性。某些粉尘具有可燃性这时就应挑选阻燃性能的除尘布袋。防静电除尘滤袋专门用于具有荷电性的粉尘。
2, the flammability and charge of dust. Some dusts are flammable, and flame retardant bags should be selected. Antistatic dust filter bag is specially used for charged dust.
三、按美高梅在线登录网址除尘设备的清灰方法挑选除尘滤袋。
Three. Dust filter bags are selected according to the dust cleaning method of environmental protection dust removal equipment.
1,机械振动类。请求挑选滤料薄而光滑,质地柔软,有利于传递振动波的除尘滤袋。
1, mechanical vibration. Ask for a filter bag with thin, smooth, soft texture and good for transmitting vibration waves.
2,反吹类。应当挑选质地柔软,结构稳定,耐磨性好的滤袋。
2, anti blowing. A filter bag with a soft texture, a stable structure and good abrasion resistance shall be selected.
3,脉冲式。一般选用带结构的外滤圆袋。请求选用扎实,耐磨,抗张力强的。
3, pulse type. Generally, the outer filter bag with the structure is used. Request to use solid, wear-resistant, anti tensile strong.
