除塵器的作用分類特點(diǎn)
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、濕式除塵器依靠水力親潤(rùn)來(lái)分離、捕集粉塵顆粒的除塵裝置，如噴淋塔、洗滌器、沖擊式除塵器、文氏管等，在處理生產(chǎn)過(guò)程中發(fā)生的高濃度、大風(fēng)量的含塵氣體場(chǎng)合采用較多。對(duì)較粗的，親水性粉塵的分離效率比干式機(jī)械除塵器要高。
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、顆粒層除塵器以不同粒度的顆粒材料堆積層為濾料來(lái)阻隔過(guò)濾氣溶中所含粉塵的設(shè)備。主要用在建材、冶金等生產(chǎn)過(guò)程中的排塵點(diǎn)，經(jīng)常是過(guò)濾濃度高、顆粒粗、溫度較高的含塵煙氣。
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、袋式除塵器，該過(guò)濾器是以纖維織造物或填充層為過(guò)濾介質(zhì)的除塵裝置，他的用途、形式、除塵風(fēng)量規(guī)模和作用效率各方面都有寬闊的范圍，主要用在捕集微細(xì)粉塵的場(chǎng)所，即在排氣除塵系統(tǒng)上應(yīng)用，又在進(jìn)風(fēng)系統(tǒng)上應(yīng)用。近年來(lái)，由于新型濾材的不斷開(kāi)發(fā)，纖維過(guò)濾技術(shù)的發(fā)展也隨之加速，新產(chǎn)品的不斷出現(xiàn)，應(yīng)用領(lǐng)域也日益的擴(kuò)寬。
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、電除塵器該除塵器是把含塵氣流導(dǎo)入靜電場(chǎng)，在高壓電場(chǎng)的作用下，氣體發(fā)生電離，產(chǎn)生電子和正離子，他們分別向正負(fù)兩極移動(dòng)，當(dāng)粉塵顆粒在流經(jīng)工作電場(chǎng)時(shí)負(fù)上電荷，以固定的速度向與它們所負(fù)電荷符號(hào)相反的沉降極板移去，并在那里沉降下來(lái)，從而脫離開(kāi)氣流，被收集于電除塵器中。這種除塵器的除塵效率高，阻力低，維護(hù)和管理方便。它在捕集細(xì)小的粉塵顆粒方面與袋式除塵器有異曲同工之效。
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.
