背景技术Background technique
在当今社会经济大发展的时代，工业发展给人类带来进步的同时，也给社会带来了诸多的负面影响，大气污染就是其中之一，它不仅给国民经济带来巨大的损失，同时也给人们的生活带来严重的危害。工业废气中含有的大量污染物是造成我国大气污染的重要原因。 In today's era of great social and economic development, while industrial development has brought progress to mankind, it has also brought many negative impacts to society. Air pollution is one of them. It not only brings huge losses to the national economy, but also Serious harm to people's lives. The large amount of pollutants contained in industrial waste gas is an important cause of air pollution in our country. the
目前工业废气的处理设备类型主要有吸收设备、吸附设备、催化净化设备、低温等离子体治理设备等，这些废气处理设备在一定程度上减少了废气的排放，但仍然存在诸多问题，例如，对呼吸性粉尘吸收率不高、消耗燃料、处理成本高、易形成二次污染、净化率低等缺点。近些年来我国出现了许多“雾霾事件”，就是由于工业废气处理设备对直径小于2.5微米的污染物颗粒的处理效果不好，造成了严重的大气污染。因此，开发一种新型废气处理设备成为目前该领域亟待解决的问题。 At present, the types of industrial waste gas treatment equipment mainly include absorption equipment, adsorption equipment, catalytic purification equipment, low-temperature plasma treatment equipment, etc. These waste gas treatment equipment have reduced the emission of waste gas to a certain extent, but there are still many problems, for example, for breathing It has the disadvantages of low absorption rate of permanent dust, fuel consumption, high processing cost, easy to form secondary pollution, and low purification rate. In recent years, there have been many "smog incidents" in my country, because industrial waste gas treatment equipment is not effective in treating pollutant particles with a diameter of less than 2.5 microns, resulting in serious air pollution. Therefore, developing a new type of exhaust gas treatment equipment has become an urgent problem in this field. the
