耐火材料適用的除塵設備有哪些?

來源:/   发布时间:2019-06-28 14:00:05
  在耐火資料消費車間的型磚加工設備作業時,會有大量的粉塵産生,所以耐火資料加工車間應當裝置除塵器來管理環境,這樣耐火資料廠才會到達環保部門的請求,當然除塵器分爲多種,那麽可適用于耐火資料廠的除塵設備有哪些呢?
  There will be a lot of dust in the brick processing equipment operation of the refractory material consumption workshop, so the refractory material processing workshop should install a dust collector to manage the environment, so that the refractory material factory can reach the request of the environmental protection department. Of course, there are many kinds of dust collectors, so what dust removal equipment can be applied to the refractory material factory?
  1、袋式除塵器
  1. Bag filter
  袋式除塵器是一種較大型的除塵設備,近年來這種除塵器在耐火資料廠運用越來越多。本設備的優點就是除塵效率高,可達99.98%以上;可處置含塵氣體濃度範圍大,由數毫克/米3至數千毫克/米3;最小除塵粒度可達0.1微米。因而它是目前耐火資料消費中較爲理想的除塵設備。
  Bag dust collector is a large-scale dust removal equipment. In recent years, this kind of dust collector has been used more and more in refractory reference plants. The advantages of this equipment are high dust removal efficiency, up to 99.98%, large range of disposable dust-containing gas concentration, from several milligrams/m 3 to thousands of milligrams/m 3, and minimum dust removal particle size up to 0.1 micron. Therefore, it is an ideal dust removal equipment in the consumption of refractory materials.
  袋式除塵器工作原理:含塵氣體從進氣口進入除塵器,經過除塵布袋將粉塵殘留在除塵布袋表面面,淨氣則從排氣口排出。
  The working principle of bag filter: Dust-containing gas enters the dust collector from the intake port, and the dust remains on the surface of the bag through the bag, while the clean air is discharged from the exhaust port.
  袋式除尘器开端工作时,除尘布袋表面面附着粉尘少,所以气体透过除尘布袋很容易。但随着附着在除尘布袋表面面粉尘增加,使气体经过除尘布袋阻力增加,到达一定水平后就会影响除尘效果,因而需求采取各种办法抖落除尘布袋上的粉尘,以保证气体正常经过。目前运用较多采用电磁控制器或者机械控制器,使紧缩空气经过文氏管向除尘布袋内部作瞬时(普通为0.1 秒)喷吹(称之为脉冲),形成除尘布袋向外剧烈扩张使粉尘零落。通常将采用电磁阀控制称为电磁脉冲阀;用机械控制器控制称为机械脉冲。这两种脉冲袋式除尘器在我国耐火资料厂中均被采用。
光氧催化設備
  When the bag filter starts to work, there is less dust on the surface of the bag, so it is easy for the gas to pass through the bag. However, with the increase of dust attached to the surface of the bag, the resistance of the gas passing through the bag increases, which will affect the dust removal effect after reaching a certain level. Therefore, various methods are needed to shake off the dust on the bag in order to ensure the normal passage of the gas. At present, electromagnetic or mechanical controllers are mostly used to make the compressed air pass through the Venturi tube to inject instantaneously (usually 0.1 seconds) into the dust bag (called pulse), forming a dust bag to expand outward and scatter dust. Generally, electromagnetic valve control is called electromagnetic pulse valve, and mechanical controller control is called mechanical pulse. These two kinds of pulse bag filter have been used in our country's refractory data factory.
  2、旋風除塵器
  2. Cyclone Precipitator
  旋風除塵器是一種應用向心力作用的除塵器。其工作原理:含塵氣體在旋風除塵內作旋轉運動,其粉塵在向心力作用下與氣體別離並從出料口排出。
  Cyclone dust collector is a kind of dust collector using centripetal force. Its working principle: Dusty gas rotates in cyclone dust removal, and its dust separates from the gas under centripetal force and is discharged from the outlet.
  旋風除塵器主要優點設備結構簡單,價錢廉價,除塵效率高(可達70~80%)。特別對粉塵粒度大、含塵濃度高含塵氣體,有良好除塵效果。因此在耐火資料消費中被普遍運用。但這種除塵器缺陷對粒度在5微米以下粉塵別離效果不佳。
  The main advantages of cyclone dust collector are simple structure, low price and high dust removal efficiency (up to 70-80%). Especially for dust with large particle size and high dust concentration, it has good dust removal effect. Therefore, it is widely used in the consumption of refractory materials. But the defect of this kind of dust collector is not good for separating dust with particle size less than 5 micron.
