PM2.5 monitoring instrument market will expand

From the end of last year to the beginning of this year, haze weather continued to occur in the central and eastern regions of North China, Huanghuai, Jianghuai, and Jiangnan, and the PM2.5 concentration in many areas continued to be extreme and suffered severe air pollution. In the face of "having a long-lasting" haze, the Ministry of Environmental Protection requires strict inspections in all parts of China, focusing on the prevention and control of fine particles, and strictly controlling air pollution.

In recent days, a large wave of air pollution caused by straw burning has swept across major agricultural production provinces, causing serious harm and impact to the people's health and travel. The PM2.5 monitor in Anhui Province has even appeared close to the explosion. Numerical value. Then we can not distinguish the PM2.5, the relevant departments of the monitoring staff is how to get valid data? Taking a monitoring point in an area as an example, let everyone understand the detection process.

Several sampling tubes for collecting air samples are erected on the roof of the EPA monitoring station in a certain area of ​​China. The collection tube is connected to the monitoring equipment of the monitoring station. After the air enters the pipeline, particles in the air will be “screened”. The particles settle out and particles smaller than or equal to 2.5 microns in diameter will enter the instrument. This is the PM2.5 that has recently attracted attention.

The PM2.5 monitoring principle is similar to that of PM10, which is an inhalable particulate matter. It is analyzed and monitored through a sample on a filter paper. After a period of operation, the white filter paper in the monitoring instrument is closely packed with coin-sized black dots. PM2.5 and other information will be printed on the tape in the form of black spots. The black spots on the tape are formed once per hour and finally converted into data through automatic analysis. This data is the concentration of PM2.5 in the air during a specific period of time.

PM2.5 monitoring market will expand

"PM2.5 is actually an indicator of comprehensive performance of air quality. In addition to monitoring equipment, it is even more noteworthy for industrial pollution control industries. To reduce PM2.5 emissions, it is necessary to upgrade existing dust removal, desulfurization and denitrification equipment and strengthen supervision. It will also further propose new standards for governance, which in effect means the formation of new markets,” industry experts pointed out.

Previously, Wuhan Environmental Protection Bureau had introduced that before and after the test, equipment investment in desulfurization and denitrification of power plants, and additional waste gas treatment devices, etc., need to be invested. The market will reach trillions of grades.

Industry analysis pointed out that the promotion of PM2.5 monitoring in batches in phases will bring about the expansion of the PM2.5 monitoring instrument market. According to the estimation of Minsheng Securities, the procurement budget for the first batch of 74 urban monitoring equipments in 2012 reached 660 million yuan. The promotion of 116 cities in the second phase of this time will surely bring about a larger space for equipment procurement.

It is worth noting that the "Indicators and Requirements" issued by the Central Environmental Monitoring Station are regarded as "passes for equipment procurement." All cities must purchase models that meet the requirements of the terminus, and the final monitored PM2.5 concentration data will be able to obtain environmental protection. Ministry accreditation. This means that with the expansion of the PM2.5 monitoring market, Environmental Protection and Concentration Technology will get more purchase orders from them, which will further increase the market share of the two companies in the national PM2.5 surveillance market.

Domestic equipment cost advantages obvious

The industry believes that the most important feature of domestic equipment is that the price is more reasonable, and maintenance costs also have advantages over imported products. Compared with the previous batch of selected equipment companies, the number of selected companies this year has increased, it can be seen that the country seems more inclined to domestic equipment, and more and more foreign instrument companies began to pay attention to China's PM2.5 monitoring equipment market . The Chinese government pointed out in the Implementation Plan for Monitoring the Second Phase of the New Air Quality Standard that, under the same conditions, priority should be given to equipment and equipment that are cost-effective and that domestic equipment be purchased in accordance with the relevant requirements of government procurement. This is undoubtedly a little more competitive advantage for local companies.

China has a vast area and there is a large gap between temperature, humidity, atmospheric pressure, and particulate matter characteristics in different regions. There are also great differences in the concentrations of PM2.5 and chemical compositions, especially in large differences in conditions and high concentrations of pollution. When the atmospheric pressure is low, there is a big difference between the foreign equipment monitoring data and the manual reference method. Under certain environmental conditions, the instrument cannot work normally and can not meet the requirements of different regions and specific conditions for the equipment.

The market layout of big cities has basically been completed. It is hoped that in the soon-to-be-started prefecture-level city and county-level market, the country can advocate for preferential procurement of domestically produced equipment and give more support to independent brands, providing a fair and open environment for domestic enterprises to participate in competition. . The market space for future air quality monitoring equipment is very broad. To monitor urban air, we must also monitor industrial sources such as thermal power and iron and steel. The market for monitoring equipment should be more occupied by domestically-made equipment rather than buying expensive equipment and services at high prices.
