【Chemical machinery and equipment network Industry dynamics】Cold air has arrived, and recently, all parts of the country are preparing for the autumn and winter air pollution prevention and control battle
.
At the regular press conference of the Ministry of Ecology and Environment in October, the spokesperson revealed that the atmospheric pollution meteorological conditions in key areas such as Beijing-Tianjin-Hebei and surrounding areas, the Fenwei Plain, and the Yangtze River Delta in the winter of 2022 are relatively unfavorable and prone to highly polluted weather, which needs attention
.

For a long time, under the influence of low pressure, high humidity, strong temperature inversion, heating demand and other factors, autumn and winter are the key periods
for the high incidence of air pollution in China.
In response to this situation, since 2017, the Ministry of Ecology and Environment has continuously carried out prevention and control actions in key areas and achieved obvious results
.
During the Winter Olympics at the beginning of this year, "Beijing Blue" once brushed the screen, and the average concentration of PM2.
5 was controlled at 36 micrograms / cubic meter, which was a world of difference from 90 micrograms / cubic meter ten years ago
.

The blue sky has visibly increased, and the international community has also highly praised it, even calling it the "Beijing miracle"
.
On November 13, according to South Korean media reports, the Beijing-Tianjin-Hebei region, which has a large impact on South Korea's meteorology, has achieved remarkable results in atmospheric environment control, and South Korea's smog responsibility should no longer be "dumped" to China
.

Of course, as the prevention and control of air pollution in autumn and winter moves in depth, the space available for emission reduction is narrowing day by day, and the current difficulty of governance is no longer an order of magnitude from before, and problems frequently arise when local governments promote precise control, including clean heating transformation
that is closely related to people's livelihood issues.

For the "one-size-fits-all" method of sealing stoves and furnaces, the Ministry of Ecology and Environment reiterated at its regular press conference in October that it must "ensure that the people are warm through the winter", and continue to use the original heating method for those who have not completed the transformation after entering the heating season; If the new renovation this year does not have the conditions for safe and stable ventilation and has not yet undergone one year's actual operation test, the original coal-fired heating facilities will not be demolished; In mountainous areas that do not have the conditions for transformation for the time being, clean coal and other methods can be used for heating
.

In terms of funds, at the end of October 2021, the Ministry of Finance has issued subsidies for clean heating operations this year amounting to 5.
35 billion yuan
.
In terms of implementation, various places are also actively seeking more economical and practical clean heating solutions, and "golden ideas" are frequently produced:

In Haiyan, Zhejiang, the first nuclear energy heating demonstration project in southern China, CNNC Qinshan Nuclear Power Nuclear Energy Heating Demonstration Project, is under construction, which is expected to meet the local heating demand of about 4 million square meters and reduce the annual consumption of standard coal by about 24,600 tons.

In Ezhou, Hubei Province, a project adopts biomass pyrolysis multi-generation production, which can comprehensively utilize 53,000 tons of agricultural and forestry waste every year for 6,000 surrounding farmers to use gas and excess gas for power generation;

In Tongzhou, Beijing, the geothermal heating pilot demonstration project of the 0701 block of the sub-center of the city will start at the end of the year, and it is planned to build 5 new geothermal wells, 1 heat source station, with 68% of the geothermal installed capacity, and municipal heat as the peak shaving heat source, with a total energy supply area of 353,000 square meters
.

The above-mentioned spokesperson said that the Ministry of Ecology and Environment will further strengthen dispatch spot checks, timely dispatch relevant local government departments for on-site verification of complaints involving clean heating, urge the first time to solve problems, and ensure that the people are clean and warm for the winter
.
