布袋式除尘器的除灰高效率是与它的除灰原理离不开的.烟尘汽体由除尘设备下边进气歧管道,经挡水板板进到料仓时,因为挡水板板的撞击和汽体速率的减少等功效,粗粒烟尘将掉入料仓中,其他细微颗粒物烟尘随汽体进到除尘布袋室,因为,清洁后的汽体逸出袋外,经排汽管排出来.除尘布袋上的积尘用汽体逆洗法除去,消除出来的烟尘放到料仓,经两层星型卸料器排在输灰设备.除尘布袋上的积尘还可以选用煤气发生炉单脉冲气旋的方式除去,进而超过除灰的目地,消除出来的烟尘由排袋式除尘器的除尘效率高也是与滤料分不开的,滤料性能和质量的好坏,直接关系到袋式除尘器性能的好坏和使用寿命的长短.而过滤材料是制作滤袋的主要材料,它的性能和质量是促进袋式除尘技术进步,影响其应用范围和使用寿命.

The dust removal efficiency of a bag filter is inseparable from its principle of ash removal. When the smoke and dust body enters the bin through the baffle plate and enters the bin under the lower side of the dust removal device, the coarse particles will fall into the silo due to the impact of the baffle plate and the reduction of the steam rate, and other fine particles will enter the dust bag room with the steam as the steam comes out of the bag. Steam pipe discharges. Dust deposited on the bag is removed by reverse washing of the vapor body. The dust removed is placed in the bin and discharged into the ash conveying equipment by two-layer star discharger. Dust deposited on the bag can also be removed by single pulse cyclone of the gas generator, which exceeds the purpose of dust removal. The dust removed by the bag filter has high dust removal efficiency and is inseparable from the filter material. The filter material is also inseparable from the filter material. The performance and quality of bag filter are directly related to the performance and service life of bag filter. The filter material is the main material for making filter bag. Its performance and quality promote the technological progress of bag filter and affect its application scope and service life. [2]

过虑式除灰设备包含布袋除尘器和颗粒物层除尘设备,前面一种一般 运用有机纤维或无机物纤维材料制成的除尘布袋作过虑层,而后面一种的过虑层多选用不一样粒度的颗粒物,如石英沙、河沙、陶粒砂、粉煤灰等构成.伴着粉末状反复的粘附于除尘布袋外表层;脉冲阀膜片发出指令,左右淹没时脉冲阀开启,高压气包内的压缩空气通了,如果没有灰尘了或是小到一定的程度了,机械清灰工作会停止工作.

The former one is made of organic or inorganic fibers, while the latter one is made of particles of different sizes, such as quartz sand, River sand, ceramsite sand, fly ash and so on. When the diaphragm gives instructions, the pulse valve opens and the compressed air in the high-pressure air chamber opens. If there is no dust or small enough, the mechanical cleaning will stop working.

底压单脉冲布袋除尘器的净化气体方法为外滤式,烟尘汽体由挡水板管进到各模块过虑室,因为设计方案中除尘布袋底离进气口上口垂直距离有充足、有效的气旋根据适度挡水板和大自然流入遍布,超过全部过虑室内空气质量遍布匀称,烟尘汽体中的,随气流进入中箱体过滤区,吸附在滤袋外表面.过滤后的洁净气体透过滤袋经上箱体、排风管排出.

The method of purifying gas of bottom pressure single pulse bag filter is external filter type. The smoke and dust vapor body enters into each module's mistake chamber from the baffle tube. Because in the design scheme, there are sufficient and effective cyclones flowing into the middle chamber according to the appropriate baffle and nature, which are more uniform than all the excessive indoor air quality. The smoke and dust vapor body enters into the middle chamber with the airflow. The filter area is adsorbed on the outside surface of the filter bag. The filtered clean gas is discharged through the upper box and exhaust duct through the filter bag.

除尘布袋选用空气压缩开展煤气发生炉除灰,除灰组织由气包、喷锅炉吹管和电磁脉冲调压阀等构成.过虑房间内每行除尘布袋出入口顶端装配线有一条喷锅炉吹管,喷锅炉吹管下侧正对除尘布袋管理中心下设喷吹口,每根喷锅炉吹管上均下设1个脉冲电磁阀并与空气压缩气包互通.清灰时,电磁阀打开脉冲阀,压缩空气经喷由清灰控制装置(差压或定时、手动控制)按设定程序打开电磁脉冲喷吹,压缩气体以极短促的时间按次序通过各个脉冲阀经喷吹管上的喷嘴诱导数倍于喷射气量的空气进入滤袋,形成空气波,使滤袋由袋口至底部产生急剧的膨胀和冲击振动,造成很强的清灰作用,抖落滤袋上的粉尘. [3]

The dust bag is compressed by air to carry out the ash removal from the gas producer. The ash removal structure is made up of air bag, spray boiler blowpipe and electromagnetic pulse regulating valve. There is a blowpipe boiler on the top assembly line of every dedusting cloth bag inlet and outlet in the room. The lower side of the spraying boiler tube is blowing the blowhole on the bottom of the dust bag management center, and there are 1 pulse electromagnetic valves and air pressure on each boiler blowpipe. When cleaning, the solenoid valve opens the pulse valve, and the compressed air is sprayed by the dust cleaning control device (differential pressure or timing, manual control) to open the electromagnetic pulse injection according to the set procedure. The compressed gas is induced into the filter bag by the nozzles on the injection tube through each pulse valve in a very short time sequence, forming air wave, which causes the filter bag to be generated from the bag mouth to the bottom. Rapid expansion and shock vibration, resulting in a strong dust removal effect, shake off the dust on the filter bag. [3]

优点

Advantage

⑴除灰高效率,通常在99%左右,除尘设备出入口汽体烟尘浓度值在十余mg/m3以内,对亚μm粒度的细尘有较高的等级分类高效率.

(1) ash removal efficiency is usually about 99%, and the concentration of smoke and dust in the inlet and outlet of the dust removal equipment is less than 10 mg/m3, which has a high grade classification efficiency for sub micron m fine dust.

⑵处理风量的范围广,小的仅1min数m3,大的可达1min数万m3,既可用于工业炉窑的烟气除尘,减少大气污染物的排放.

(2) The range of air handling capacity is wide, the small number of M3 is only 1 minute, and the large one can reach tens of thousands of m3 in one minute. It can be used for flue gas dust removal of industrial furnaces and kilns to reduce the emission of atmospheric pollutants.

⑶结构简单,维护操作方便.

_The structure is simple and easy to maintain and operate.

⑷在确保一样高除灰高效率的前提条件下,工程造价小于静电除尘器.
