锅炉布袋除尘器烟尘处理工艺流程及其说明
Process flow and description of flue dust treatment for bag filter of boiler
1). 工艺选择
1. Process selection
锅炉烟气是锅炉燃料遇热挥发、分解、燃烧时产生的微粒.这些微粒分散在空气中形成飘浮烟型气溶尘,微粒中大部分为细微粒,粒径在0.01-10μm之间,比重:3-10g/cm3.根据其重度、颗粒度,可采用喷淋沉降、旋风分离、袋式过滤等常规方法去除.根据厂方的要求和具体工艺参数,此方案设计为旋风除尘器为初级除尘,布袋除尘器为二级除尘的综合治理.
Boiler flue gas is a kind of particulate matter produced by the volatilization, decomposition and combustion of boiler fuel when heated. These particulates disperse in the air to form floating flue gas-soluble dust. Most of them are fine particulates with particle size ranging from 0.01 to 10 micron and specific gravity ranging from 3 to 10 g/cm3. According to their gravity and particle size, spray sedimentation, cyclone separation and bag filter can be used. According to the requirements of the factory and the specific technological parameters, the scheme is designed as the comprehensive treatment of cyclone dust collector as primary dust collector and bag dust collector as secondary dust collector.
①旋风除尘器专用于收集粒径较大、比重较大的粉尘,除尘效率也较低,属于初级除尘设备,XLP/B型除尘器是一种带有旁路通道的高效旋风除尘器,用于清除工业废气中含有非纤维性及黏结性的灰尘,能有效地分离烟草灰、滑石粉、石英粉、石灰粉、矿渣水泥、水泥生料等,具有结构简单、操作方便、耐高温、阻力低而除尘效率高的碳、化工及电力工业部的气体净化.
(1) Cyclone dust collector is specially used to collect dust with larger particle size and larger specific gravity, and its dust removal efficiency is low. It belongs to primary dust removal equipment. XLP/B type dust collector is an efficient cyclone dust collector with bypass passage. It is used to remove non-fibrous and cohesive dust from industrial waste gas, and can effectively separate tobacco ash, talcum powder and stone. British powder, lime powder, slag cement, raw cement, etc. have simple structure, easy operation, high temperature resistance, low resistance and high dust removal efficiency of the Ministry of Carbon, Chemical Industry and Power Industry gas purification.
②锅炉布袋除尘器是厂在总结国内外先进单机脉冲阀技术的优点研制开发的一种小型高效脉冲布袋除尘器,它次用高压(0.5-0.7MPa) 、大流量脉冲阀逐排滤袋喷吹清灰,具有结构紧凑、体积小、清灰能力大、清灰效果高、收尘效率高的特点.
(2) Boiler bag filter is a small high-efficiency pulse bag filter developed by the factory in summarizing the advantages of advanced single-machine pulse valve technology at home and abroad. It uses high pressure (0.5-0.7 MPa) and large flow pulse valve to blow the filter bag one by one. It has compact structure, small volume, large dust removal capacity, high dust removal effect and high dust collection efficiency. Characteristic.
锅炉布袋除尘器排放标准20毫克
Boiler bag filter discharge standard 20 mg
1.设计烟气量
1. Design Flue Gas Volume
根据常规生物质锅炉燃烧是产生烟气量理论数据,确定该1T生物质锅炉运行时将产生约为3000m3/h的烟气量.
According to the theoretical data of flue gas generated by conventional biomass boiler combustion, it is determined that the flue gas generated by the 1T biomass boiler will be about 3000 m3/h when it runs.
2.排放标准
2. Emission standards
经处理后所要求的指标达到《大气污染物排放标准》 (GB13223-2003)第二时段标准,具体如下表:
After treatment, the required indicators meet the second time period standard of the Air Pollutant Discharge Standard (GB13223-2003), as follows:
污染物 烟尘排放浓度 mg/m3 SO2排放浓度 mg/m3 NOx排放浓度(mg/m3) 烟气黑度(林格曼黑度,级)
Emission Concentration of Pollutant Smoke and Dust mg/m3 SO2 Emission Concentration mg/m3 NOx Emission Concentration (mg/m3) Smoke Blackness (Ringman Blackness, Grade)
