Description
技术领域 technical field
本发明涉及一种烟气污染治理技术，尤其是一种应用于湿式静电除尘器的外布水移动式柔性集尘极装置。The invention relates to a flue gas pollution control technology, in particular to a water-distributed mobile flexible dust collecting electrode device applied to a wet electrostatic precipitator.
背景技术 Background technique
目前，随着《火电厂污染物排放标准》（GB 13223 2011）正式实施以及《环境空气质量标准》（GB 3095 2012）正式发布，对于超细颗粒物的排放控制正式展开。作为大气中颗粒物质的重要排放源的燃煤电厂，虽然都安装有除尘器，但普遍采用的是干式静电除尘器（ESP），这种除尘器集尘极在干态下运行，不但对于容易形成反电晕的高比电阻粉尘颗粒收集效率低，而且对于10μm（特别是2.5μm）以下微细颗粒，由于微细粒子难以荷电，而且电极振打产生二次扬尘容易使已捕集的微细粒子逸出，导致脱除效率急剧下降。大量微细粉尘颗粒的逃逸造成烟尘浓度排放过大，不但难以满足新的标准要求，而且由于对人体有毒有害的主要污染物大多富集在10μm以下的微细粉尘颗粒中，大量微细粉尘颗粒的逃逸也严重影响了人们的身体健康，造成巨大的经济损失。At present, with the official implementation of the "Pollutant Emission Standards for Thermal Power Plants" (GB 13223 2011) and the official release of the "Ambient Air Quality Standards" (GB 3095 2012), the emission control of ultrafine particles has been officially launched. As an important emission source of particulate matter in the atmosphere, coal-fired power plants are all equipped with dust collectors, but dry electrostatic precipitators (ESP) are commonly used. The dust collectors of this kind of dust collectors operate in a dry state. The collection efficiency of dust particles with high specific resistance that is easy to form back corona is low, and for fine particles below 10 μm (especially 2.5 μm), it is difficult to charge the fine particles, and the secondary dust generated by electrode vibration is easy to make the collected fine particles Particles escape, resulting in a sharp drop in removal efficiency. The escape of a large number of fine dust particles causes excessive smoke concentration, which is not only difficult to meet the new standard requirements, but also because most of the main pollutants that are toxic and harmful to the human body are concentrated in fine dust particles below 10 μm, the escape of a large number of fine dust particles is also difficult. It has seriously affected people's health and caused huge economic losses.
采用湿式集尘极能够有效克服干式集尘极的反电晕问题并能防止微细颗粒二次扬尘，因此能够有效提高静电除尘特别是脱除微细粉尘的效率。但目前工业应用的湿式集尘极一般都是由金属等硬性材料组成，由于表面张力及机加工平面度偏差等问题，冲洗水不可能在整个集尘极表面完全均布，容易在集尘极表面形成“沟流”，这样水流冲洗不到的地方容易导致尘粒的累积与结垢，如不及时拆卸清理，最终会导致集尘极失效；烟气中含有的酸雾等成分较易腐蚀普通材料的金属集尘极，因此大部分金属集尘极采用成本较高的合金材料制成。上述问题已使得采用湿式集尘极的静电除尘器设备运行稳定性、安全可靠性、经济性等方面受到了严重影响。The use of wet dust collecting poles can effectively overcome the back corona problem of dry dust collecting poles and prevent secondary dusting of fine particles, so it can effectively improve the efficiency of electrostatic dust removal, especially the removal of fine dust. However, the wet dust collecting poles currently used in industrial applications are generally composed of hard materials such as metals. Due to problems such as surface tension and machining flatness deviations, it is impossible for the flushing water to be completely evenly distributed on the entire surface of the dust collecting poles, and it is easy to flow on the dust collecting poles. The surface forms a "channel flow", so that the place where the water flow cannot wash is easy to cause the accumulation and scaling of dust particles. If it is not disassembled and cleaned in time, it will eventually lead to the failure of the dust collection; the acid mist and other components contained in the flue gas are more likely to corrode Metal dust collecting poles of common materials, so most metal dust collecting poles are made of alloy materials with higher cost. The above problems have seriously affected the operational stability, safety, reliability, and economy of electrostatic precipitators using wet dust collectors.
另外，中国专利ZL200910019222.7公开了一种纤维织物集尘极表面水膜均匀化装置及工艺，该工艺通过在集尘极上端密布Ф1-Ф2mm的布水孔，水在重力作用下向下流动，利用纤维毛细作用，实现水膜的均布。但是这种工艺装置由于仅在集尘极上端安装布水装置，水膜只能由上端向下延伸，对于面积较大的集尘极，容易形成集尘极上端水膜厚度过大而下端水膜厚度不够的问题，影响水膜的均匀分布；另外，上述专利中集尘极为固定布置，仅靠灰糕层与集尘极表面张力和收缩比不同实现集尘极的清灰，容易导致清灰不彻底，影响后续除尘效率。In addition, Chinese patent ZL200910019222.7 discloses a device and process for homogenizing the water film on the surface of the fiber fabric dust collecting pole. In this process, water holes of Ф1-Ф2 mm are densely distributed on the upper end of the dust collecting pole, and the water flows downward under the action of gravity. , using fiber capillary action to achieve uniform distribution of water film. However, because this kind of process device only installs the water distribution device on the upper end of the dust collecting pole, the water film can only extend downward from the upper end. The problem of insufficient film thickness affects the uniform distribution of the water film; in addition, the dust collector in the above-mentioned patents is extremely fixed, and the dust removal of the dust collector is achieved only by the difference in surface tension and shrinkage ratio between the dust cake layer and the dust collector, which may easily lead to cleaning. The ash is not thorough, which will affect the follow-up dust removal efficiency.

The flexible dust collecting pole 4 is a plate-shaped body made of flexible fabric. The water distribution device 2 is a steel pipe with small holes or grooves. There are two kinds of spraying angles of small holes or grooves on the steel pipe: tangential angle and normal angle close to the tangent point.
随着电压升高，电极3端放电使空气电离，产生大量负离子；烟气中的粉尘颗粒与负离子结合后，向柔性集尘极2运动。布有均匀水膜的柔性集尘极捕获运动到集尘极的粉尘颗粒，由于水的粘滞力，颗粒特别是微细颗粒不会发生二次返混问题，实现微细颗粒的高效捕集；柔性集尘极在沿气流方向前后运动过程中，布水装置从接近切点切向、法向角度向集尘极喷水，实现水膜的持续均匀分布与清灰，另外，也可通过集尘极与布水装置2的摩擦，实现集尘极的自动清灰。As the voltage rises, the terminal 3 of the electrode discharges to ionize the air and generate a large amount of negative ions; the dust particles in the flue gas combine with the negative ions and move towards the flexible dust collecting electrode 2.

此时柔性集尘极在垂直于气流方向上下运动过程中，布水装置从接近切点切向、法向角度向集尘极喷水，实现水膜的持续均匀分布与清灰。为保证集尘极上下运动过程中不跑偏，转动轴两端均安装有限位装置。集尘极2可通过喷水清灰，也可通过集尘极与布水装置2的摩擦，实现集尘极的自动清灰。At this time, when the flexible dust collecting pole is moving up and down perpendicular to the airflow direction, the water distribution device sprays water to the dust collecting pole from the tangential and normal angles close to the tangential point, so as to realize the continuous and uniform distribution of the water film and the cleaning of dust. In order to ensure that the dust collector does not deviate during its up and down movement, limit devices are installed at both ends of the rotating shaft. The dust collecting pole 2 can be cleaned by spraying water, or by the friction between the dust collecting pole and the water distributing device 2, so as to realize the automatic dust removal of the dust collecting pole.
