Description
Technical Field
The utility model relates to a filter bag, concretely relates to compound glass fiber woven filter bag.
Background
The domestic environment protection situation is getting more severe, and the serious situation of haze surrounding city continuously appears in recent years. The industrial dust is the main cause of haze, and the treatment work is not slow at all. The state has issued policies for controlling smoke emission and controlling air pollution, and the policies and measures specifically include policies and measures such as 'twelve five' energy-saving and environment-friendly industry development plan, 'ten measures for air pollution prevention and control,' action plan for air pollution prevention and control, 'GB 4915-2013 emission standard of cement industry air pollutants', and the like. The pollutants of industrial production mainly comprise smoke dust and SO2、SO3、NOx、CO2、N2And other harmful substances, heavy metals and the like, and the characteristics of the substances are different due to different working conditions.
Along with the frequent appearance of the haze weather, the society draws increasing attention to emission reduction of the industrial smoke and dust, and the industrial smoke and dust serving as the haze weather mainly serves as an emission-limiting and emission-reducing object. The power industry supports the rapid development of national economy, brings serious environmental pollution, is one of main emission sources of industrial smoke dust, and is a key field of domestic pollution emission reduction. In the power industry, main pollutants in the coal-fired power generation process are carbon dioxide, sulfur dioxide, nitrogen oxides, fluorides, dust and the like, and the coal-fired power generation process is characterized in that waste gas has certain corrosivity and the dust is light and fine and has high harmfulness. Therefore, the smoke control in the power industry is important.
At present, high-temperature filter materials used by a bag type dust collector in the power industry mainly comprise a glass fiber needled felt filter material, a glass fiber/PTFE (polytetrafluoroethylene) composite felt filter material, a glass fiber laminated filter material and the like. The glass fiber needled felt filter material and the glass fiber/PTFE composite filter material both belong to non-woven filter materials, and are needled felt filter materials prepared by a needling processing technology, so that firstly, the strength of a needled felt filter material base cloth layer is reduced due to needling damage, the tensile strength of the filter material is low, the dimensional stability is poor, and the filter material is easy to damage after long-term use; secondly, after the filter material is used for a long time, dust is easy to accumulate in the filter material, so that the filter material is blocked, the system resistance is directly increased, and the normal operation of a dust removal system is influenced.
