Description
本发明属于环保领域，涉及一种除尘除雾器，具体涉及一种嵌入式静电除尘除雾器。The invention belongs to the field of environmental protection, and relates to a dust eliminator and mist eliminator, in particular to an embedded electrostatic dust eliminator and mist eliminator.
随着《煤电节能减排升级与改造行动计划(2014—2020年)》的实施以及各地方政府对于超低排放要求严格，燃煤机组烟囱入口烟尘排放浓度须达到超低排放水平(≤5mg/m
3)，目前常用的技术路线为低低温电除尘器+脱硫协同除尘及新增湿式电除尘器。
With the implementation of the "Coal Power Energy Saving and Emission Reduction Upgrading and Retrofit Action Plan (2014-2020)" and the strict requirements of local governments for ultra-low emissions, the concentration of smoke and dust at the inlet of the chimney of coal-fired units must reach an ultra-low emission level (≤5mg /m 3 ), the current common technical route is low-temperature electric precipitator + desulfurization cooperative dust removal and newly-added wet electric precipitator.
低低温电除尘器+脱硫协同除尘是静电除尘器前设置烟气冷却器并对静电除尘器进行相应改造同时优化设计脱硫塔喷淋层和除雾器，其主要原理是使大部分SO
3在烟气降温过程中凝结并被烟尘(烟气冷却器出口烟气温度低于酸露点温度并工作在高灰区域)充分的吸附和捕集，导致烟尘粒径增大和比电阻降低，大大提高静电除尘器除尘效率；通过后部湿法脱硫系统优化设计，如增加除雾器级数或增设高效除雾器等，提高烟气治理系统的除尘效率，确保达到超低排放要求。其缺点在于为了确保脱硫系统除尘效率需增设高效除雾器，必然会增大设备阻力，且对于前级除尘设备要求较高，运行效果影响因素较多。
Low and low temperature electrostatic precipitator + desulfurization cooperative dust removal is to set up a flue gas cooler before the electrostatic precipitator and carry out corresponding transformations to the electrostatic precipitator while optimizing the design of the spray layer of the desulfurization tower and the demister. The main principle is to make most of the SO 3 in The flue gas is condensed during the cooling process and is fully absorbed and trapped by the flue gas (the flue gas temperature at the outlet of the flue gas cooler is lower than the acid dew point temperature and works in the high ash area), resulting in an increase in the particle size of the smoke and a decrease in the specific resistance, which greatly improves the static electricity Dust removal efficiency of the dust collector; through the optimization design of the rear wet desulfurization system, such as increasing the number of demister stages or adding a high-efficiency demister, etc., the dust removal efficiency of the flue gas treatment system is improved to ensure that the ultra-low emission requirements are met. The disadvantage is that in order to ensure the dust removal efficiency of the desulfurization system, it is necessary to add a high-efficiency demister, which will inevitably increase the resistance of the equipment, and the requirements for the front-stage dust removal equipment are relatively high, and there are many factors affecting the operation effect.
湿式电除尘器除尘是向电场空间输送直流负高压，通过空间气体电离，烟气中粉尘颗粒和雾滴颗粒荷电后在电场力的作用下，收集在收尘极表面，利用在收尘极表面形成的连续不断的水膜及定时喷淋冲洗将粉 尘冲洗去除。由于处于饱和湿烟气环境下工作，改善了电晕放电条件；同时由于液滴的存在及烟气温度较低，降低了粉尘比电阻；另外湿式电除尘器没有振打装置，没有二次扬尘对除尘效果带来的负面影响，可以确保达到超低排放要求。其缺点在于需新增一套设备，不论何种布置方式均需较大的布置空间，增加阻力较大。The dust removal of wet electrostatic precipitator is to deliver DC negative high voltage to the electric field space. Through the ionization of space gas, dust particles and fog drop particles in the flue gas are charged and collected on the surface of the dust collector under the action of the electric field force. The continuous water film formed on the surface and regular spray flushing will flush and remove the dust. Because it works in a saturated wet flue gas environment, the corona discharge conditions are improved; at the same time, due to the presence of droplets and the lower flue gas temperature, the specific resistance of dust is reduced; in addition, the wet electrostatic precipitator has no rapping device and no secondary dust The negative impact on the dust removal effect can ensure that the ultra-low emission requirements are met. The disadvantage is that a new set of equipment needs to be added, which requires a larger layout space regardless of the layout method, and the increase in resistance is relatively large.

为达到上述目的，本发明所述的嵌入式静电除尘除雾器包括壳体、高压电源以及设置于壳体内的若干除尘除雾组件，各除雾除尘组件均包括放电极及收尘除雾装置，壳体的一侧设置有进气口，壳体的另一侧设置有出气口；In order to achieve the above purpose, the embedded electrostatic dust and mist eliminator of the present invention includes a housing, a high-voltage power supply, and a number of dust and mist eliminators arranged in the housing, and each defog and dust eliminator includes a discharge electrode and a dust collecting and defogging device. , One side of the housing is provided with an air inlet, and the other side of the housing is provided with an air outlet;
从进气口至出气口的方向，各除雾除尘组件依次分布，各除雾除尘组件中的放电极与收尘除雾装置依次分布；From the air inlet to the air outlet, the defogging and dust removal components are distributed in sequence, and the discharge electrode and dust collecting and defogging devices in each defogging and dust removal component are distributed in sequence;
高压电源与各除雾除尘组件中的放电极相连接。The high-voltage power supply is connected with the discharge electrode in each defogging and dust removal assembly.
还包括用于对各除雾除尘组件中的收尘除雾装置进行冲洗的捕集水滴自流及定时冲洗装置。It also includes a self-flow and timing washing device for catching water droplets for washing the dust collecting and defogging devices in each defogging and dust removal assembly.
同一除尘除雾组件中放电极与收尘除雾装置之间的间距为500mm-700mm。The distance between the discharge electrode and the dust collecting and defogging device in the same dust removing and defogging assembly is 500mm-700mm.
高压电源为恒流电源或者高效电源。The high-voltage power supply is a constant current power supply or a high-efficiency power supply.
本发明具有以下有益效果：The present invention has the following beneficial effects:
本发明所述的嵌入式静电除尘除雾器在具体操作时，放电极对烟气 中的粉尘及雾滴进行预荷电，并对微细粉尘及雾滴进行电凝并，之后在电场力、惯性撞击及离心力的作用下，将粉尘及雾滴铺集到收尘除雾装置表面，除尘除雾效果好，需要说明的是，本发明通过电场力的作用对微细粉尘及雾滴进行电凝并且改变粉尘及雾滴运动轨迹，大大提高惯性撞击除尘除雾效果。另外本发明仅需布置于原脱硫除雾器位置处，利用原有空间采用一级或多级布置，对原有结构不产生大的影响，相对于湿式电除尘器不需新的布置空间，相对于常规除雾器可至少节省一级除雾器布置空间。相对于湿式电除尘器由于不用新增一套除尘设备，阻力可降低约250Pa；相对于常规除雾器由于减少了收尘装置布置级数，阻力可降低约100Pa。During the specific operation of the embedded electrostatic precipitator and mist eliminator of the present invention, the discharge electrode precharges the dust and mist in the flue gas, and performs electrocoagulation on the fine dust and mist. Under the action of inertial impact and centrifugal force, the dust and mist droplets are collected on the surface of the dust collecting and defogging device, and the effect of dust removal and mist removal is good. It should be noted that the present invention performs electrocoagulation on fine dust and mist droplets through the action of electric field force. And change the movement trajectory of dust and fog drop, greatly improving the effect of inertial impact dust removal and mist removal. In addition, the present invention only needs to be arranged at the position of the original desulfurization and demister, using the original space to adopt one-level or multi-level layout, which does not have a large impact on the original structure, and does not require new layout space compared with wet electrostatic precipitators. Compared with conventional demisters, at least one level of demister arrangement space can be saved. Compared with the wet electrostatic precipitator, because there is no need to add a new set of dust removal equipment, the resistance can be reduced by about 250Pa; compared with the conventional mist eliminator, the resistance can be reduced by about 100Pa due to the reduction of the number of dust collection devices.
