Industrial dust pollution becomes a new hot spot for atmospheric environmental management

On the 5th, the Ministry of Environmental Protection issued the "Twelfth Five-Year Plan for Air Pollution Prevention and Control in Key Areas", in which the prevention and control of atmospheric pollution during the "Twelfth Five-Year Plan" period includes sulfur dioxide treatment, oil and gas recovery, yellow label vehicle elimination, dust comprehensive improvement, and capacity building. For key projects, the total investment demand is as high as 350 billion yuan.

Respond to PM2.5 monitoring and management

According to the "Planning", one of the key tasks of air pollution control during the "Twelfth Five-Year Plan" period is to implement coordinated control of multiple pollutants. The emission control of sulfur dioxide and nitrogen oxides has been fully promoted before, especially since the “Eleventh Five-Year Plan”, the flue gas desulfurization market in key industrial fields has been fully infiltrated, and the flue gas denitration market in the power industry is also opening.

It is worth noting that the planning of industrial smoke dust control will be a separate chapter, suggesting that during the “Twelfth Five-Year Plan” period, industrial smoke dust control will be strengthened and particulate emissions will be greatly reduced.

In fact, this also echoes the country’s vigorous promotion of national PM2.5 monitoring and management since last year. According to experts, in view of the future work of PM2.5, in addition to the “four steps” proposed by the Ministry of Environmental Protection, the monitoring is carried out nationwide. On the other hand, the more important task is to control PM2.5 from the source. Emissions from sources of pollution. These sources of pollution mainly come from soot emissions from the industrial sector.

In view of this, the "Planning" highlights the need to fully implement dust and particulate matter treatment in key areas such as thermal power, cement and steel. Among the eight key projects for the prevention and control of atmospheric pollutants listed in the “12th Five-Year Plan”, there are as many as 10,000 industrial smoke dust control projects involving an investment of 47 billion yuan.

Standard improvement

According to experts, as the country's emission standards for major pollutants in the industry are becoming more stringent, the field of industrial smoke dust control will gradually phase out the dust-removing technology with weaker control effects and turn into a comprehensive replacement period for bag-type dust removal technology.

Take the power industry as an example. Assume that during the “Twelfth Five-Year Plan” period, the market share of bag dust removal will increase to 50%, and the market demand for high-performance high-temperature filter materials will reach 40 million cubic meters. The average annual compound growth rate of market demand will reach 47. %, by 2013, the high-performance high-temperature filter material market formed by dust removal in the power industry can reach nearly 10 billion yuan.
