1、干式机械除尘器，主要指应用粉尘惯性作用、重力作用而设计的除尘设备，如沉降室、惰性除尘器、旋风除尘器等高浓度的除尘器等，主要针对高浓度粗颗粒径粉尘的分离或浓集而采用。
1. Dry mechanical dust collector mainly refers to the dust removal equipment designed by the application of dust inertia and gravity, such as settling chamber, inert dust collector, cyclone dust collector and other high concentration dust collectors. It is mainly used for the separation or concentration of high concentration coarse particle size dust.
2、湿式除尘器依靠水力亲润来分离、捕集粉尘颗粒的除尘装置，如喷淋塔、洗涤器、冲击式除尘器、文氏管等，在处理生产过程中发生的高浓度、大风量的含尘气体场合采用较多。对较粗的，亲水性粉尘的分离效率比干式机械除尘器要高。
2. Wet dust collectors rely on hydraulic lubrication to separate and capture dust particles, such as spray tower, scrubber, impact dust collector, venturi, etc., which are widely used in the treatment of high concentration and large air volume dust gas in the production process. The separation efficiency of coarse and hydrophilic dust is higher than that of dry mechanical dust collector.
3、颗粒层除尘器以不同粒度的颗粒材料堆积层为滤料来阻隔过滤气溶中所含粉尘的设备。主要用在建材、冶金等生产过程中的排尘点，经常是过滤浓度高、颗粒粗、温度较高的含尘烟气。
3. Granular layer dust collector is a kind of equipment which uses granular material accumulation layer with different particle size as filter material to block and filter the dust contained in air solution. Mainly used in building materials, metallurgy and other production process of dust discharge point, often filter high concentration, coarse particles, high temperature dust flue gas.

4、袋式除尘器，该过滤器是以纤维织造物或填充层为过滤介质的除尘装置，他的用途、形式、除尘风量规模和作用效率各方面都有宽阔的范围，主要用在捕集微细粉尘的场所，即在排气除尘系统上应用，又在进风系统上应用。近年来，由于新型滤材的不断开发，纤维过滤技术的发展也随之加速，新产品的不断出现，应用领域也日益的扩宽。
4. Bag filter is a dust removal device with fiber fabric or filling layer as filtering medium. It has a wide range of uses, forms, dust removal air volume scale and efficiency. It is mainly used in places where fine dust is collected, that is, in the exhaust dust removal system and in the air inlet system. In recent years, due to the continuous development of new filter materials, the development of fiber filtration technology is also accelerated, the continuous emergence of new products, the application field is also expanding.
5、电除尘器该除尘器是把含尘气流导入静电场，在高压电场的作用下，气体发生电离，产生电子和正离子，他们分别向正负两极移动，当粉尘颗粒在流经工作电场时负上电荷，以固定的速度向与它们所负电荷符号相反的沉降极板移去，并在那里沉降下来，从而脱离开气流，被收集于电除尘器中。这种除尘器的除尘效率高，阻力低，维护和管理方便。它在捕集细小的粉尘颗粒方面与袋式除尘器有异曲同工之效。
5. Electrostatic precipitator the precipitator is to introduce the dust laden air flow into the electrostatic field. Under the action of the high voltage electric field, the gas ionizes and produces electrons and positive ions. They move to the positive and negative poles respectively. When the dust particles flow through the working electric field, they are negatively charged and move to the settling plate with the opposite sign of their negative charges at a fixed speed, and they settle down there, Thus, the air flow is separated and collected in the electrostatic precipitator. The dust collector has the advantages of high dust removal efficiency, low resistance and convenient maintenance and management. It has the same effect as bag filter in catching fine dust particles.
