布袋除尘器正压除尘和负压除尘的使用

袋除尘器正压除尘和负压除尘的优缺点:(1)正压除尘系统,布袋除尘器 正压式(又称压入式)除尘器内部气体压力高于大气压力,正压式 布袋 除尘器引风机安装在除尘器含尘烟气进口端,在除尘器墙体内产生正压力,易将含尘或腐蚀物烟气导入除尘器,不易安装在室内,也不易处理毒性大的含尘烟气 。
The advantages and disadvantages of positive pressure dust removal and negative pressure dust removal of bag dust collectors: (1) positive pressure dust removal system. The positive pressure (also known as pressure in type) dust collector has an internal gas pressure higher than atmospheric pressure, and the positive pressure bag dust collector's induced draft fan is installed at the inlet end of the dust containing flue gas in the dust collector, which generates positive pressure inside the dust collector wall, making it easy to introduce dust or corrosive flue gas into the dust collector and difficult to install indoors, It is also difficult to handle highly toxic dust containing smoke.
但含尘或腐蚀物烟气通过风机内部,容易对风机造成损伤及磨损;正压式袋式除尘器的特点是外壳结构简单轻便,密封性要求不高,造价低,且布置紧凑。
However, smoke containing dust or corrosive substances passing through the interior of the fan can easily cause damage and wear to the fan; The characteristics of positive pressure bag filter are simple and lightweight shell structure, low sealing requirements, low cost, and compact layout.
正压除尘系统中的除尘器应设置在通风机之后。其特点如下。
The dust collector in the positive pressure dust removal system should be installed after the ventilation fan. Its characteristics are as follows.
除尘器
①由于除尘器设置在通风机后,含尘气体未经除尘器净化先流过通风机,通风机的叶轮和机壳极易遭粉尘磨损。因此正压除尘系统只适用于气体含尘浓度小于3g/m3,粉尘磨损性弱、力度小的情况。
① Due to the dust collector being installed behind the ventilator, the dusty gas flows through the ventilator before being purified by the dust collector, making the impeller and casing of the ventilator highly susceptible to dust wear and tear. Therefore, the positive pressure dust removal system is only suitable for situations where the dust concentration in the gas is less than 3g/m3, the dust wear resistance is weak, and the force is small.
②由于除尘器处于通风机的正压段,不必考虑除尘器的漏风率,通风机电耗较低。
② Due to the fact that the dust collector is located in the positive pressure section of the ventilator, there is no need to consider the air leakage rate of the dust collector, and the mechanical and electrical consumption of the ventilator is relatively low.
③除尘器的维护结构简单,如正压袋式除尘器的维护结构不需要密封,只需采取防雨措施即可;设备制造与安装简便,造价低。
③ The maintenance structure of the dust collector is simple, for example, the maintenance structure of the positive pressure bag filter does not need to be sealed, only rainproof measures need to be taken; The equipment manufacturing and installation are simple and low in cost.
④除尘器有一定的消声作用,通风机出口侧可不设消声器;有利节约除尘系统占地,减少初始投资。
④ The dust collector has a certain noise reduction effect, and there may not be a silencer installed on the outlet side of the fan; Beneficial for saving dust removal system land and reducing initial investment.
