Description

一种PM2.5综合处理装置 技术领域
本实用新型涉及污染空气处理技术领域，尤其涉及一种PM2.5综合处理装置。
背景技术
PM2.5是指大气中直径≤2.5微米的颗粒物，也称可入肺颗粒物，2013年2月，全国科学技术名词审定委员会将PM2.5的中文名称命名为“细颗粒物”，它的直径不到人头发丝粗细的1/20。虽然PM2.5只是地球大气成分中含量很少的组成部分，但它对空气质量和能见度等有重要的影响。与较粗的大气颗粒物相比，PM2.5粒径小，富含大量的有毒、有害物质，且在大气中的停留时间长、输送距离远，因而对人体健康和大气环境质量的影响更大。
并且，随着现代化社会的不断发展，PM2.5指数的国际标准也在不断提高，十几年前制定的PM2.5的指数标准是65微克每立方米，十年后又将标准制定在35微克每立方米。而现在中国的PM2.5指数的标准是75微克每立方米，这主要是参考我国发展的水平以及技术条件来决定的。
PM2.5颗粒产生的主要来源，是日常发电、工业生产、汽车尾气排放等过程中经过燃烧而排放的残留物，大多含有重金属等有毒物质。一般而言，粒径2.5-10微米的粗颗粒物主要来自道路扬尘、风沙、工农业活动等机械过程；PM2.5中一次颗粒物(直接排放到大气中的颗粒物)主要来自化石燃料燃烧和生物质燃烧产生的飞灰以及多种无机和有机化合物，如机动车尾气、燃煤、挥发性有机物、森林野火等；PM2.5中二次颗粒物(间接生成的颗粒物)主要来源是大气中的气态物质(二氧化硫、氮氧化物、气态氨以及挥发性有机物等)通过发生化学反应而形成的颗粒物(如硫酸铵颗粒、硝酸铵颗粒、有机化合物颗粒等)。在世界上大多数地区，PM2.5的二次来源比例往往高于一次来源。
随着我国工业的蓬勃发展，环境污染对人们身体健康的危害日益凸现，环境整治已经到了刻不容缓的地步。空气污染指标PM2.5成为现在热门的话题，PM2.5之所以被高度重视，源于PM2.5形成的复杂性，顽固性，长期性，以及对其整治的高难度性。现在市场上的PM2.5静电除尘装置要么就臭氧量过大，要么就出来带静电，不是理想的除尘设备。因此，本领域的技术人员致力于开发一种PM2.5综合处理装置，解决现有技术的不足。
实用新型内容
有鉴于现有技术的上述缺陷，本实用新型所要解决的技术问题是提供一种PM2.5综合处理装置，其结构简单，实用性强，成本较低，除尘效果好，不会残留大量臭氧和静电，有效解决了现有技术的不足。
为实现上述目的，本实用新型提供了一种PM2.5综合处理装置，其特征在于：包括用于产生高频脉冲的高频震荡驱动电路、用于吸收被污染空气的风机、用于实现将污染空气中颗粒物带上负电的第一级空气处理网、用于吸引第一级空气处理网处理后的颗粒物的第二级空气处理网、用于将带静电的空气中静电释放到大地的第三级空气处理网，所述高频震荡驱动电路输出端与升压变压器初级连接，所述升压变压器次级与桥堆整流器的两个交流输入端连接，桥堆整流器的负直流输出端与第一级空气处理网连接，桥堆整流器的正直流输出端与第二级空气处理网连接，所述第三级空气处理网一端接地。

本实用新型的有益效果是：
本实用新型结构简单，实用性强，成本较低，除尘效果好，不会残留大量臭氧和静电，有效解决了现有技术的不足。
以下将结合附图对本实用新型的构思、具体结构及产生的技术效果作进一步说明，以充分地了解本实用新型的目的、特征和效果。
附图说明
图1是本实用新型的整体结构示意图。
图2是本实用新型的高频震荡驱动电路原理图。
具体实施方式
如图1所示，一种PM2.5综合处理装置，其特征在于：包括用于产生高频脉冲的高频震荡驱动电路1、用于吸收被污染空气的风机2、用于实现将污染空气中颗粒物带上负电的第一级空气处理网3、用于吸引第一级空气处理网3处理后的颗粒物的第二级空气处理网4、用于将带静电的空气中静电释放到大地的第三级空气处理网5，所述高频震荡驱动电路1输出端与升压变压器6初级连接，所述升压变压器6次级与 桥堆整流器的两个交流输入端连接，桥堆整流器的负直流输出端与第一级空气处理网3连接，桥堆整流器的正直流输出端与第二级空气处理网4连接，所述第三级空气处理网5一端接地。
本实施例中，所述桥堆整流器的正直流输出端与负直流输出端之间连接有隔直电容。
本实施例中，所述所述桥堆整流器的正直流输出端与第二级空气处理网4之间还连接有扼流圈，用于滤除直流电压的杂波。
本实施例中，所述第一级空气处理网3、第一级空气处理网4、第一级空气处理网4均为金属网。
本实用新型的工作原理是：
高频震荡驱动电路产生高频脉冲电压，经过升压变压器的升压在升压变压器的次级形成高压脉冲，高压脉冲经过整流桥堆整流输出负直流高压和正直流高压，其中桥堆整流器的负直流输出端与第一级空气处理网连接，利用空气处理网的尖端直流高压产生高电晕，高速地放出大量的电子(e-)，而电子无法长久存在于空气中(存在的电子寿命只有nS级)，立刻会被空气中的氧分子(02)捕捉，从而生成空气负离子，这时由风机吸入的污染空气的颗粒物都会带上负电荷；桥堆整流器的正直流输出端与第二级空气处理网连接，第二级空气处理网上会带正电荷，然后第一级空气处理网处理后的带负电荷的污染颗粒物被第二级空气处理网上带正电荷的高频脉冲吸引沾到金属网上，然后空气中基本没有PM2.5了；最后把带静电的空气经过接地的第三级空气处理网把静电引到大地，这样就出来安全的清新空气了。经过以上工序处理过后的空气不会残留大量臭氧和静电，不会带来附加的麻烦，有效解决了现有技术的不足。
以上详细描述了本实用新型的较佳具体实施例。应当理解，本领域的普通技术人员无需创造性劳动就可以根据本实用新型的构思做出诸多修改和变化。因此，凡本技术领域中技术人员依本实用新型的构思在现有技术的基础上通过逻辑分析、推理或者有限的实验可以得到的技术方案，皆应在由权利要求书所确定的保护范围内。
