Definitions
- the invention relates to the technical field of dust removing devices, in particular to a fabric, a pole plate and a flue gas synergistic purification device.
- the wet electrostatic precipitator is generally treated with wet-saturated flue gas after wet desulfurization.
- the particulate matter in the outlet flue gas reaches an "ultra-low" or even lower index.
- the wet electrostatic precipitator of the flexible plate has the advantages of less flushing water consumption and no alkali consumption compared with the rigid electrode plate (glass fiber reinforced plastic or stainless steel) wet electrostatic precipitator.
- the flexible plate is generally made of acid-resistant organic fiber material, and is usually woven by pure short wire, and the surface has a developed fluff structure.
- the surface of the plate In the wet saturated flue gas environment, the surface of the plate is due to capillary wicking.
- There is a layer of water film so that the plate has a certain self-cleaning function; at the same time, due to the water storage and water retention function of the fiber material, it keeps the wet state in the wet saturated flue gas environment for a long time, thus eliminating the need for continuous water supply conditions. Underneath, meet and maintain the necessary electrical conductivity requirements of the plates.
- the organic fiber material is used for the anode cloth mentioned in the patent 201610819283.1.
- the wet electrostatic precipitator is a new dust removal device for treating trace dust and micro particles. It is mainly used to remove harmful substances such as dust, acid mist, water droplets, aerosols, odor and PM2.5 in wet gas. It is the ideal equipment for controlling atmospheric dust pollution.
- the wet type electrostatic precipitator is usually referred to as WESP. It is basically the same as the dust removal method of the dry type electrostatic precipitator. The dust is charged by the high voltage corona discharge, and the charged dust reaches the dust collecting plate/tube under the action of the electric field force. It has to go through three stages of charging, collecting and cleaning.
- the wet electrostatic precipitator uses liquid to flush the surface of the dust collecting surface for cleaning, which can effectively collect fine particles (PM2.5 dust, SO3 acid mist, aerosol), heavy metals (Hg, As, Se, Pb, Cr) and organic pollution. (polycyclic aromatic hydrocarbons, dioxins) and the like.

In the lower part of the plate, the water film is biased to the side of the plate, as shown in Fig. 1. It is difficult to form a water film covering the entire surface of the electrode plate, and the area covered by the waterless film forms dust accumulation, which affects the dust removal efficiency.
- the surface of the plates is smoother and has no such texture.
- water tends to form a "twig"-like channel on the surface of the plates, and it is also difficult to form a full surface of the plate. Water film.

- the anode column of the flexible wet dust collector has certain incompatibility during use, has a long manufacturing cycle, consumes a large amount of manpower and material resources during installation, and considers transportation costs, resulting in an increase in economic costs.
- the anode column occupies a small portion of the dust collecting plate space, and increases the cross-sectional area of the wet dust collector shell under the condition that the dust collecting pole area is constant, and the weight thereof is heavy, and the supporting frame and the supporting beam model are large, resulting in wet dust removal.

Description
本发明涉及除尘装置技术领域,具体而言,涉及一种织物、极板及烟气协同净化装置。
湿式静电除尘器的处理对象一般为经过湿法脱硫后湿饱和烟气,通过降低烟气中的酸雾滴、细颗粒物含量,使出口烟气中颗粒物达到“超低”、甚至更低指标。
柔性极板的湿式静电除尘器与刚性极板(玻璃钢或不锈钢)湿式静电除尘器相比,具有冲洗水耗量少,无碱耗等突出优势。原因在于柔性极板一般为耐酸有机纤维材料制成,且通常采用纯短丝机织而成,其表面具有发达的绒毛结构,在湿饱和烟气环境中,由于毛细芯吸作用,极板表面有一层水膜,从而使极板具备一定的自清洁功能;同时,由于纤维材料的蓄水、保水功能,使其在湿饱和烟气环境中长时间保持潮湿状态,从而无需持续布水的条件下,达到并保持极板必需的一定的导电性的要求。专利201610819283.1提及的阳极布采用的就是此种有机纤维材料。
然而,由于传统柔性纤维均采用纯短丝机织,表面较粗糙,颗粒物或粉尘与极板的粘附力较强,颗粒物或粉尘需要较大的水量、较快的水速方可以冲洗下来,随着国家对燃煤电站颗粒物排放指标日益严格,以及为了适应更加复杂的工业烟气净化要求,同时减少冲洗水耗水量,柔性极板的自清洁功能及导电功能需要进一步提升,以防止有积灰及其进而引发的反电晕现象的产生,从而影响除尘效率。
此外,近年来,随着污染物“超低排放”改造在全国的开展,湿式电除尘器被广泛推广和应用。湿式电除尘器是一种用来处理含微量粉尘和微颗粒的新除尘设备,主要用来除去含湿气体中的尘、酸雾、水滴、气溶胶、臭味、PM2.5等有害物质,是治理大气粉尘污染的理想设备。湿式电除尘器通常简称WESP,与干式电除尘器的除尘基本原理相同,都是靠高压电晕放电使得粉尘荷电,荷电后的粉尘在电场力的作用下到达集尘板/管,要经历荷电、收集和清灰三个阶段。湿式电除尘器采用液体冲刷集尘极表面来进行清灰,可有效收集微细颗粒物(PM2.5粉尘、SO3酸雾、气溶胶)、重金属(Hg、As、Se、Pb、Cr)、有机污染物(多环芳烃、二噁英)等。使用湿式电除尘器后含湿烟气中的烟尘排放可达10mg/m3甚至5mg/m3以下,收尘性能与粉尘特性无关,适用于含湿烟气的处理,尤其适用在电厂、钢厂湿法脱硫之后含尘烟气的处理上,但设备投资费用较高,且需与其它除尘设备配套使用,其投资技术经济性和运行成本要从整体进行评价。
湿式静电除尘器(以下简称“湿电”)的处理对象一般为经过湿法脱硫后湿饱和烟气,通过降低烟气中的酸雾滴、细颗粒物含量,使出口烟气中颗粒物达到“超低”、甚至更低指标。 按照阳极收尘极板的形式不同,湿电可分为柔性极板湿电与刚性极板湿电。极板作为湿电集尘极,其上水膜是否高效均布直接影响湿电对颗粒物的去除效率。
对于柔性极板而言,极板一般选用纤维织物,纤维织物由纱线机织而成,且多采用斜纹织,织物表面呈现具有一定斜纹角度的纹理。这产生的不利影响为:在工程应用过程中,极板表面的水流在纹理的导流作用下按照一定的角度流动,在极板下半部分,水膜偏向极板一侧,如图1所示,较难形成覆盖极板全表面的水膜,无水膜覆盖的区域形成积灰,影响除尘效率。
对于刚性极板而言,极板表面较光滑,无上述纹理结构,然而,由于缺乏导流作用,水在极板表面易形成“枝丫”状的沟流,同样较难形成覆盖极板全表面的水膜。
由于上述两种极板存在的表面物理特性,在实际工程中均需要较大的冲洗水量方可以形成覆盖全表面的水膜以完成清灰,这增加了湿电的耗水量及其相关的电耗、碱耗等。为了适应更加复杂的、颗粒物进口浓度变化大的烟气净化要求,亟需一种极板,来减少冲洗水耗水量,实现小水量布水条件下水膜均布,进而确保高效除尘效率。
湿式电除尘器是一种用来去除湿烟气中携带的液滴、气溶胶、PM2.5等有害物质的环保设备,是治理烟气粉尘污染的理想设备。随着火电厂、炼钢厂等达到超低排放标准及节能改造,湿式电除尘器应用日益广泛。湿式电除尘器按收尘极板分为刚性极板、柔性极板及玻璃钢湿式电除尘器。其中,柔性湿式电除尘器采用优良的有机纤维作为阳极收尘极板,在处理脱硫后湿烟气过程中“近零水耗”、“零碱耗”水膜整体均布性好、运行费用低、检修维护方便等诸多优势,应用广泛。
目前,柔性湿式电除尘器主要由阴极系统、阳极系统组成,而阳极系统又主要由阳极上下花板、立柱、收尘极板(柔性极板)等组成。阳极上下花板起限位支撑立柱的作用,立柱是用来固定柔性极板的,如发明专利201610819283.1提供的柔性湿式电除尘器收尘极板固定装置及柔性湿式除尘器。然而,该类柔性湿式除尘器的阳极立柱在使用过程中存在一定的不适应性,加工制造周期长,安装时消耗大量的人力、物力,并考虑运输费用,导致经济成本增加。
同时,阳极立柱占用小部分收尘极板的空间,在收尘极面积不变的情况下增加湿式除尘器壳体横截面积,且自身重量重,支撑框架及支撑梁型号大,致使湿式除尘器设备所需材料量增加,造成材料的浪费,加工制造及安装费用增加,造成总体建设不经济等现象。
综上,目前的柔性湿式电除尘器阳极立柱占用小部分收尘极板空间,加工制造、安装、运输费用高,支撑框架及支撑梁材料量增加等造成总体建设不经济,阳极系统结构急需改进。

本发明通过控制经纬线的粗细、织法、织物的克重、厚度、纹理角度等因素保证其强度、表面张力、水膜均布等要求,能够更好的消除表面纹理造成织物表面水膜偏流,提高强度、维持表面的张力与平整。

在具体实施例中,相邻的两个极板区域表面上斜纹纹理的角度相等。
在该实施例中,相邻的两个极板区域表面上斜纹纹理的角度设置为相等的角度,能够保证水膜在各个极板区域表面流速以及方向相同,有利于水膜在各个极板区域表面的均匀分布。
在具体实施例中,在每个极板区域内,斜纹纹理的角度越大,沿经线方向的距离越大,斜纹纹理之间水平距离越小,水膜偏流越严重。
(一)当极板为柔性极板时,该极板采用上述的柔性纤维织物制作而成:
对于柔性极板而言,极板由经线1、纬线2斜纹机织而成,在经向,斜纹纹理以左、右斜或右、左斜交替方式呈现。
而且述柔性极板由具有相应斜纹纹理的极板区域拼接而成,或所述柔性极板表面上的斜纹纹理由织机制成。
需要说明的是,当极板为柔性极板时,斜纹纹理在极板区域左右方向交替,可通过设置织机参数实现,或对织物进行裁剪、拼接等后处理方式实现。
如图1所示,在第一极板区域表面内,经向距离极板上顶端一段距离d
11内,斜纹向左/右斜,斜纹与纬向的夹角为α
11(锐角方向);
在第二极板区域表面内,沿经线方向的长度距离d
12内,斜纹又改为向右/左斜,斜纹与纬向的夹角为α

本发明针对柔性极板,条纹纹理以左/右或右/左交替方式呈现,避免了纹理方向单一进而带来的偏流现象;
本发明通过湿电极板表面结构的改变,实现了较少量布水情况下,水膜在极板上的均匀分布,一方面可以提高清灰的效果,另一方面避免了大水量冲洗,较大程度上减少了废水产生量。
(二)当极板为刚性极板时:
刚性极板表面上的斜纹纹理由机床加工或模具拉挤成型。
在本实施例中,刚性极板可采用玻璃钢或不锈钢来实现。当为不锈钢时,斜纹纹理在极板区域左右方向交替,可通过数控机床如铣床加工而成;当为玻璃钢时,斜纹纹理在极板区域左右方向交替,可通过设置模具参数拉挤成型实现。

22=1m内,斜纹又改为向右斜,斜纹与纬向的夹角为α
22=60°(锐角方向),在极板长度方向上述左、右斜均重复出现2次。基于烟气 的性质及烟气协同净化装置出口颗粒物的浓度要求,上述单块极板的长度d
24=6m;所述纹理之间的距离d
23=为0.3mm,斜纹凸起的高度d
25=0.05mm。
上述刚性极板的参数,基于烟气的性质及烟气协同净化装置出口颗粒物的浓度要求,能够最大程度上减缓水膜偏流发生,保证刚性极板表面90%以上面积均有水膜存在,从而保障水膜对极板上积灰的清除效果。
对于刚性极板,在其表面增加左、右方向交替的条纹,同样可对表面的水膜起到导流作用,有效避免了“枝丫”状偏流的发生。
