一．電袋復(fù)合除塵器概述

1.A summary of electricity composite filter bag
電袋復(fù)合式除塵器是有機(jī)結(jié)合了靜電除塵和布袋除塵的特點(diǎn)，通過(guò)前級(jí)電場(chǎng)的預(yù)收塵、荷電作用和后級(jí)濾袋區(qū)過(guò)濾除塵的一種高效除塵器，它充分發(fā)揮電除塵器和布袋除塵器各自的除塵優(yōu)勢(shì)，以及兩者相結(jié)合產(chǎn)生新的性能優(yōu)點(diǎn)，彌補(bǔ)了電除塵器和布袋除塵器的除塵缺點(diǎn)。該復(fù)合型除塵器具有效率高，穩(wěn)定，濾袋阻力低，壽命長(zhǎng)，占地面積小等優(yōu)點(diǎn)，是未來(lái)控制細(xì)微顆粒粉塵、PM2.5以及重金屬汞等多污染物協(xié)同處理的主要技術(shù)手段。

Electricity compound bag precipitator is organic combination of the characteristics of the electrostatic dust collection and bag dust removal, dust deposit by level before the electric field, the function and level after charged area filter bag filter dust removal of a highly efficient dust catcher, it give full play to the electric dust collector and dust advantages of bag dust collector, as well as the combination of both to create new performance advantages, make up for the shortcomings of electrostatic precipitator and cloth dust collector. The composite filter with high efficiency, stable, filter bag low resistance, long service life, cover an area of an area small, etc, will be the future control of tiny particles of dust, PM2.5 and more pollutants such as heavy metal mercury together to deal with the main technical means.

二．結(jié)構(gòu)形式

2. Structure form
前級(jí)電除塵區(qū)秉承了電除塵器電場(chǎng)的除塵優(yōu)勢(shì)，其除塵效率與極板有效面積呈指數(shù)曲線變化，能收集煙塵中大部分粉塵，收塵效率達(dá)70-80%，并使流經(jīng)電除塵區(qū)未被收集下的微細(xì)粉塵電離荷電。一方面大大降低進(jìn)入布袋除塵器區(qū)含塵濃度，另一方面荷電后的粉塵在濾袋沉積的粉餅呈低阻特性，從而既達(dá)到排放濃度小于30mg/Nm3的環(huán)保要求，又提高了除塵器整體性能的功效。

Level before the electric area receives the first electric field of electrostatic precipitators, its dust removal efficiency and the effective area of exponential curve plate, can collect most of the smoke dust, dust collecting efficiency of 70-80%, and flows through the electric area has not been collected under the fine dust of ionization charged. On the one hand, greatly reduce the dust concentration of entering bag dust collector area, on the other hａnd charged dust in the filter bag after the deposition of powdery cake is of low resistance, thus achieves emission concentration is less than 30 mg/Nm3 requirements of environmental protection, and increase the effectiveness of the overall performance of the filter.

三.技術(shù)特點(diǎn)

3. Technical characteristics
（1）除塵機(jī)理：由于在電袋復(fù)合式除塵器中，煙氣先通過(guò)電除塵區(qū)后再緩慢進(jìn)入后級(jí)布袋除塵區(qū)，布袋除塵區(qū)捕集的粉塵量?jī)H有入口的1/4。這樣濾袋的粉塵負(fù)荷量大大降低，清灰周期得以大幅度延長(zhǎng)；粉塵經(jīng)過(guò)電除塵區(qū)電離荷電，粉塵的荷電提高了粉塵在濾袋上的過(guò)濾特性，即濾袋的透氣性能、清灰性能方面得到大大的改善。合理運(yùn)用電除塵器和布袋除塵器各自的除塵優(yōu)點(diǎn)，以及兩者相結(jié)合產(chǎn)生新的功能，能充分克服電除塵和布袋除塵的除塵缺點(diǎn)。根據(jù)目前的試驗(yàn)研究和在電力鍋爐煙塵的工業(yè)應(yīng)用，證明該技術(shù)是一種科學(xué)、可靠、*的技術(shù)。綜合了二種除塵方式的優(yōu)點(diǎn)。

(1) the dust removal mechanism in electricity compound bag dust collector, the flue gas through electric precipitation area and then slowly into the first grade bag dust removal after area, cloth bag dust control area, the amount of dust catcher is only a quarter of entry. The filter bag dust load is reduced greatly, soot cleaning cycle can be greatly extended; Ionization charged dust after the electric area, dust charged improve the dust on the filter bag filter characteristics, namely, the permeability of filter bag, ash removal performance have been improved greatly. Their reasonable using electrostatic precipitators and bag filter dust removal, and the combination creates new functions, can overcome the disadvantages of the electric and bag dust removal. According to the present experimental study and industrial application in power boiler soot, proved that the technology is a scientific, reliable and advanced technology. Taking advantages of the two kinds of schemes.
（2）保證長(zhǎng)期高效穩(wěn)定運(yùn)行：電袋復(fù)合式除塵器的除塵效率不受煤種、煙氣特性、飛灰比電阻影響，可以長(zhǎng)期保持高效、穩(wěn)定、可靠地運(yùn)行，保證排放濃度低于30mg/Nm3。
