電熱水鍋爐電動除塵器介紹

要了解電熱水鍋爐http://www.nys3.com/電動除塵器的特點,除塵器的作用是將煙氣中攜帶的飛灰進行分離并除去,以防止對引風機的磨損,減輕對大氣和環境的污染。

1、電熱水鍋爐電除塵器的除塵效率高達99%左右,處理氣體量大,煙氣流速低,阻力小,運行費用也低。
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、電熱水鍋爐電除塵器由集塵極、電暈極、振打裝置、氣流分布裝置、殼體以及排灰裝置等組成,電除塵器的工作過程大致可分為塵粒荷電、收集灰塵粒、清除捕集的塵粒三個階段。
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、把電熱水鍋爐針電板和平板電極相對放置,并在針電板側加以高壓直流電壓,當電場超過游離場強時,在電極針尖附近就發生急劇的火花放電,此時針電極針尖附近的氣體被電離,電暈板是除塵器中使氣體產生電暈放電的電極,它主要包括電暈線、電暈框架、框架吊桿和支撐絕緣管等。因此對它的要求是電暈放電效果好,電暈線機械強度高但又要盡量細,電暈線上的積灰要容易振落,方便安裝和維修。
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、在電熱水鍋爐http://www.nys3.com/電暈極和集塵極組成的不均勻電場中,以放電極為負極,集塵極為正極,并以60kV的高壓直流電源來充電。當這一電場強度提高到某一值時,電暈極周圍形成負電暈,氣體分子的電離作用加強,產生了大量的正、負離子。正離子被電暈極中和,負離子和自由電子則向集塵極轉移,當帶有粉塵的氣體通過時,這些帶負電荷的粒子就會在運動中不斷碰到并被吸附在塵粒上,使塵粒荷電,在電場力的作用下,很快運動到達集塵極氣陽極板,放出負電荷,本身沉積在集塵板上。在正離子的運行中,電暈區里的粉塵帶正電荷,移向電暈極,因此電暈極也會不斷積灰,只不過量較小。
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.
