要了解电热水锅炉http://www.jnshengxin.cn/电动除尘器的特点,除尘器的作用是将烟气中携带的飞灰进行分离并除去,以防止对引风机的磨损,减轻对大气和环境的污染。
1、电热水锅炉电除尘器的除尘效率高达99%左右,处理气体量大,烟气流速低,阻力小,运行费用也低。
Collection efficiency electric water boiler ESP up to about 99%, handling a large amount of gas, flue gas flow rate is low, low resistance, low running costs.
2、电热水锅炉电除尘器由集尘极、电晕极、振打装置、气流分布装置、壳体以及排灰装置等组成,电除尘器的工作过程大致可分为尘粒荷电、收集灰尘粒、清除捕集的尘粒三个阶段。
Electric water boiler electrostatic precipitator dust from pole, corona electrode, rapping device, air distribution system, housing and ash devices and other components, the working process can be divided into ESP charged dust collecting dust grains , remove the dusts collected in three stages.
3、把电热水锅炉针电板和平板电极相对放置,并在针电板侧加以高压直流电压,当电场超过游离场强时,在电极针尖附近就发生急剧的火花放电,此时针电极针尖附近的气体被电离,电晕板是除尘器中使气体产生电晕放电的电极,它主要包括电晕线、电晕框架、框架吊杆和支撑绝缘管等。因此对它的要求是电晕放电效果好,电晕线机械强度高但又要尽量细,电晕线上的积灰要容易振落,方便安装和维修。
The electric water boiler plate and needle plate electrodes placed opposite, and make high-voltage direct current voltage side of the needle plate, when the electric field strength over free when in the vicinity of the electrode tip is sharp spark discharge occurs, this time near the tip of the needle electrode gas is ionized gas corona manipulation plate is precipitator corona discharge generating electrode, which includes a corona wire, corona frame, frame insulation tube and the support boom. So its effect corona discharge requirements, high mechanical strength, but also the corona wire as small as possible, fouling Corona fall line-up to be easy, easy installation and maintenance.
4、在电热水锅炉http://www.jnshengxin.cn/电晕极和集尘极组成的不均匀电场中,以放电极为负极,集尘极为正极,并以60kV的高压直流电源来充电。当这一电场强度提高到某一值时,电晕极周围形成负电晕,气体分子的电离作用加强,产生了大量的正、负离子。正离子被电晕极中和,负离子和自由电子则向集尘极转移,当带有粉尘的气体通过时,这些带负电荷的粒子就会在运动中不断碰到并被吸附在尘粒上,使尘粒荷电,在电场力的作用下,很快运动到达集尘极气阳极板,放出负电荷,本身沉积在集尘板上。在正离子的运行中,电晕区里的粉尘带正电荷,移向电晕极,因此电晕极也会不断积灰,只不过量较小。
The electric water boiler plate and needle plate electrodes placed opposite, and make high-voltage direct current voltage side of the needle plate, when the electric field strength over free when in the vicinity of the electrode tip is sharp spark discharge occurs, this time near the tip of the needle electrode gas is ionized gas corona manipulation plate is precipitator corona discharge generating electrode, which includes a corona wire, corona frame, frame insulation tube and the support boom. So its effect corona discharge requirements, high mechanical strength, but also the corona wire as small as possible, fouling Corona fall line-up to be easy, easy installation and maintenance.
